Preface

This book has been a labor of love of mine over the past several years, and I have toacknowledge all of those who have contributed in various ways to its creation. Probably theearliest influence on my artistic talents was my paternal grandmother, Greta. If there is a genefor artistic skill, it was surely passed through her to my father and me. She and her sister weretalented painters. I still have vivid memories of the art lessons she gave me on her visits withmy family. I am also indebted to the many great artists who have inspired me over the years:Robert Taylor, Keith Ferris, R.G. Smith, William Phillips, Fredrick Remington, John SingerSergeant, Winslow Homer, Edward Hopper, Tom Lea, and many more. I can’t count the hoursI have spent pouring over their amazing paintings. Finally, I must thank my parents, family,and friends whose love and support have made me who I am.

Lesson 1: ScaffoldingAs a young, aspiring artist, I spent many happy hours copying pictures of airplanes. I

would practice drawing them over and over until I could do them from memory. With an imageto copy, I didn’t have to think about how to position and foreshorten all the parts of theairplane. The image showed me exactly what it should look like. Something that alwaysfrustrated me was that I didn’t have any way to figure out what the aircraft would look like fromother points of view - points of view for which I didn’t have a picture.

That’s why I developed the method described in this book. It is an intuitive process forrendering an airplane accurately from any point of view. The foundation of this methodinvolves creating something I call a scaffold. The scaffold is made of simple lines and shapesthat show you how to accurately foreshorten and align the parts of an airplane in yourdrawing. The process of using a scaffold to do a drawing is called scaffolding.

Scaffolding Example for Drawing an Airplane

Below is an example of a scaffold I have created to draw a WWII Japanese Zero fighter.You can see that it is made of simple geometric shapes. Though it resembles and airplane, it

doesn’t look like a Zero just yet.

My scaffold shows me how to foreshorten and align the parts of the airplane. By using itas a guide, I am able to refine the shapes of the wings, tail, and other parts of the airplane asyou can see in the image below.

Finally, I erase the scaffold and add details and shading for the finished drawing – thebeautiful Mitsubishi A6M Zero Fighter.

Using your Artist Vision

In this book I use a concept I call artist vision. Artist vision is the artist’s superpower.It may not be quite a cool as x-ray vision, but it comes close. Artist vision is what artists use tovisualize the final drawing on a page. If you’re a new artist, this can be the hardest part ofdoing a drawing. Fortunately with practice it gets easier. A scaffold is something that artistsuse to help their artist vision.

Look in any “how to draw” book and you’ll see some type of scaffolding technique. Theidea is to start with simple geometric shapes like lines, circles, or squares to approximate themajor parts of whatever you’re drawing. Then you fill in details and refine the shapes. Nomatter what you are drawing, and no matter how good of an artist you are, scaffolding is atechnique that makes it easier. Below I’ve used scaffolding to draw a portrait.

Page 11: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

In the first panel (A), I have drawn a simple stick figure to define the head, shoulder, andarms. This is my scaffold. In the second panel (B), I have noted the shape of the hair, thelocation of the eyes, nose, and mouth, and the shape of the torso. In the third panel (C), Ihave refined details like the eyes, lips, and hair. Say, she’s kind of cute!

Starting with a scaffold is important because it is much easier to make corrections to asimple stick figure than it is to a detailed drawing. I can’t tell you how many times I’ve spenthours drawing something only to realize that it was too big or too small or too close to the edgeof the frame. The only thing to do at that point is start over. Ugh!

At first it can be hard to visualize the final drawing based on your simple scaffold.That’s just something that takes practice, so don’t get discouraged if you have trouble at first.I have faith in you because I know that you are no ordinary person. You are an artist, and youhave artist vision. This book will help your artist vision to grow stronger.

Review of Scaffolding

To review, scaffolding has several advantages:

· It helps you to visualize your final picture quickly.

· It enables you to spot errors or adjust your composition before you spend a lot of timeworking on the drawing.

· It provides a step by step approach to drawing so that you will have more consistentresults.

Okay, now that you have an understanding of what I mean by scaffolding, let’s take acloser look at how to apply it to drawing airplanes.

Lesson 2: Seven Steps to Drawing Airplanes

Introduction

So Grasshopper, what I am going to teach you is a seven-step process for drawingairplanes. Although I describe this as a way to draw airplanes, you’ll find that it is just asuseful for drawing cars, boats, buildings, and any other three dimensional object you canimagine.

This lesson will provide you with an overview of the seven steps. It will help you tounderstand what you will do in each step, and the remaining lessons in the book will show youhow to do them.

Step 1: Draw a Scaffold Based on a 3-View Drawing

My process for drawing airplanes starts with the creation of a scaffold using top andside view drawings. These kinds of drawings are widely available and are called 3-viewdrawings.

Below I have drawn a scaffold for the top and side views of the P-40B Warhawk. Thisplane was made famous by the American Volunteer Group, also known as the Flying Tigers. Ihave placed the side and top views on a reference grid and drawn my scaffold around them.The reference grid will help me recreate my scaffold in perspective later on. The scaffold isdrawn with simple geometric shapes like lines and rectangles.

Page 13: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Step 2: Draw a Foreshortened Reference Grid (FRG)

In the second step, I create a three-axis reference grid in perspective. I call this aforeshortened reference grid or FRG. This will help me recreate the scaffold in perspective.The image below is my FRG.

Step 3: Transfer the Scaffold onto the FRG

Once I have drawn the FRG, I use it to recreate the scaffold using locations thatcorrespond to my reference grid drawn in step 1. The drawing below shows what the scaffoldlooks like when transferred to the FRG.

Step 4: Use Projection to Adjust the Scaffold

After I transfer the scaffold to the FRG, I need to adjust the location of some of its parts.Below I have projected the wing scaffold down and horizontal tail up a little.

Step 5: Outline and Shape the Fuselage

With my scaffold drawn in perspective, I draw the outline of the fuselage and then shapeit by drawing some fuselage bulkheads as seen below.

Step 6: Outline and Shape the Wings and Tail

In the image below, I have used my scaffold to draw the outlines of the wings and tailand then shaped them by drawing the airfoils.

Page 15: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Step 7: Clean up and Final Details

The last step involves erasing all the guides and adding final details to the drawing likepanel lines and markings. As you can see below, I have drawn it with the markings of theFlying Tigers.

Summary

I hope you can see that these seven steps will enable you to draw any airplane fromany point of view. All you need is a 3-view drawing of the airplane. Some photographicreferences are also helpful for getting all the details right. With practice, you can accomplishall the steps in a freehand drawing.

Lesson 3: Drawing a Scaffold from a 3-ViewDrawing

The Reference Grid

To create my scaffold, I first create a square reference grid. Since I usually have adigital 3-view drawing of the aircraft I’m going to draw, I make the reference grid in MicrosoftPowerPoint and then size and position the airplane drawing inside the grid. The image belowis an example of a reference grid.

Three-view drawings are widely available in books and on the internet. Be aware that not all3-view drawings are created equal. Some are definitely better than others. Take the time tofind good quality references for your drawing.

Scaffold Example 1: Supermarine Spitfire

Below is a 3-view drawing of a one of the most iconic fighters from WWII, theSupermarine Spitfire. It is not just its beautiful design that makes the Spitfire such a belovedairplane. The Spitfire holds a special place in the hearts of the British because of its role in theBattle of Britain. After the defeat of France in 1939, the German Luftwaffe waged a bombingcampaign against Britain. About 2,500 RAF pilots, flying the Spitfire and other aircraft, held offthe German attackers. This led Winston Churchill to proclaim, “Never in the field of humanconflict was so much owed so many to so few.”

Starting with the top view scaffold, I place the top view drawing in the reference grid asyou can see below. I use a square reference grid because a square is easier to foreshortenlater when I draw the FRG.

Page 18: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Next, I create a scaffold using this top view as you can see in the image below. I’veused rectangles to represent the wings and tail and a line to represent the fuselage. The twodashed lines indicate the widest part of the fuselage.

To help you see the scaffold more clearly, I have removed the top view in the imagebelow. You can also see my estimates of the locations of the scaffold lines relative to thegridlines.

Page 19: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

One thing you will notice about our scaffold is that the wingspan is longer than thelength of the fuselage. This is very typical for propeller driven aircraft. The opposite tends tobe true of fast jet aircraft where the wings can be quite a bit shorter than the fuselage.

How you draw your scaffold is up to you. The purpose of the scaffold is to have asimple structure on which to make your finished drawing. For that reason, your scaffold shouldbe composed of straight lines and simple geometric shapes like rectangles or triangles.

I make my side view scaffold a little bit differently than the top view. That is becausefrom the top, most airplanes are symmetrical around the center line. From the side view,however, they are usually not very symmetrical. Below is the side view of the Spitfire in areference grid. You will want to make sure that the side view drawing is sized the same as thetop view. If you don’t, the side and top view scaffolds won’t line up.

Page 20: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

As you can see in the next image, I draw this side view scaffold using a line for thefuselage and a rectangle for the vertical tail and rudder assembly. I have added dotted lines asa reference for the top and bottom of the fuselage and the canopy. You can add as many or asfew of these reference lines as you like. In most cases, the side view scaffold will only requireone row of grid squares above and/or below the fuselage centerline.

Removing the side view drawing, you can see the scaffold clearly below. Again, youcan see how I have estimated the approximate location of each of the scaffold’s parts usingthe reference grid. I will use these estimates when I transfer the scaffold to the FRG later.

Scaffold Example 2: The F-86 Sabre

The F-86 is an American beauty that became famous during the Korean War. It was thefirst U.S. fighter jet to have swept wings. The look of this plane even inspired the design ofmany automobiles in the 1950s. In a dive the Sabre could exceed Mach 1, and it boasted animpressive 10 to 1 kill ratio over Russian made fighters during the Korean War. Below is a3-view drawing of this famous jet. So, how would you draw a scaffold for an aircraft with sweptwings?

Below is my top view scaffold drawn on the reference grid. Notice that the F-86 fitsneatly inside of a square. Its fuselage length and wingspan are nearly the same.

Below is the scaffold with the top view removed. Use your eyeball to estimate thelocation of key points so that you can reproduce this on a FRG.

And below is my side view scaffold. However you decide to draw your scaffold,remember to keep it simple and base it on straight lines or simple geometric shapes.

Page 23: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

In the next image I have removed the side view drawing. Look at my estimates for thelocations the scaffold parts and see if you would agree.

Transferring the Scaffold onto a FRG

In the next lesson I am going to show you how to draw the foreshortened referencegrid. The FRG is a drawing of the top view and side view reference grids in perspective.Below is an example of a blank FRG.

Page 24: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Using the corresponding lines in the FRG, transferring the scaffold is not too difficult.Just use your artist vision to estimate where the lines of the scaffold should be. Here’s whatthe Spitfire scaffold looks like after transferring it to this FRG.

Below is the F-86 Sabre scaffold transferred onto another FRG. Do these scaffolds helpyou to visualize these planes?

Summary

You may be thinking after seeing these scaffolds that they don’t look very much like theairplanes on which they are based. Remember what I told you about artist vision. The key isbeing able to visualize the final drawing based on your simple scaffold. That is something thatwill get easier as your artist vision grows stronger.

Lesson 4: Drawing the Foreshortened ReferenceGrid

Introduction

In this lesson I’m going to show you how to draw a foreshortened reference gridorthographically, that is, without perspective. In the next lesson I’ll explain how to addperspective. I’m going to use Cartesian axes to explain how to draw the FRG. If you’re notfamiliar with them, the next section will tell you all you need to know.

Cartesian Coordinates: Drawing Three Dimensionally

Way back in 1637, almost 250 years before the first flight of the Wright brothers, a veryintelligent man by the name of René Descartes was laying in bed watching a fly walk acrossthe ceiling. The story goes that as he watched the fly moving about, it occurred to him that hecould describe the fly’s location using three coordinates or numbers. Now, René Descartes,just like some rock stars today, decided he wanted to be called by a different name, and so hesigned his papers Renatus Cartesius. I’ll admit it’s not as cool as Sting or Slash, but back in

the 17th century it probably passed as a cool name. This is why we refer to his fly-inspiredcoordinate system as the Cartesian coordinate system. The three coordinates are knowntoday as X, Y, and Z coordinates.

Two dimensions describe a flat plane like a piece of paper or a photograph. It has awidth (X axis) and height (Y axis), but no depth (Z axis). Look at the image below and you’llsee what I’m talking about. The fly on the graph is described with two coordinates or numbers(3,2) because it is three units over on the X axis and 2 units up on the Y axis (mathematiciansalways list the X axis coordinate first and the Y axis coordinate second).

Let’s consider a point in three-dimensions: width, height, and depth. The picture belowshows a fly in three dimensions. It is three units over on the X axis, two units over on the Y

Page 27: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

axis, and three units up on the Z axis. It is written as (3,2,3) because the coordinates arealways listed in the order of X, Y, then Z.

Something else you should notice in this three dimensional drawing is that the Y axis isdrawn shorter than the X axis. Artists call this foreshortening. Foreshortening refers to theway that lines appear to shorten as they point towards (or away from) our point of view.

Why the geometry lesson? Because these geometric coordinates give us artists auseful way to talk about drawing three dimensional objects. For example, the reference gridcan be thought of as an X-Y coordinate grid as in the image below.

Using an Oval to Foreshorten Lines

We need a tool to help us figure out how to foreshorten lines of equal length. The toolwe are going to use is an ellipse or oval. The image below illustrates what I mean. Imaginethe circle below is a pizza viewed from above. It is sliced into eight pieces. Each slice or line isthe same length. They are all equal to the diameter of the circle. Now imagine viewing thepizza from one side (known as an oblique angle or obliquely). The oval on the right showsyou how the pizza would look from that point of view.

Page 28: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

When viewed obliquely, you can see that the cuts are foreshortened to differentdegrees. Cut C isn’t foreshortened at all. This is because cut C is perpendicular to our pointof view. Cut B is foreshortened a little and A, parallel to our point of view, is foreshortened themost. When we see the oval as a foreshortened circle, any line through its center is theforeshortened diameter of the circle. Next, I’ll show you how to use this principle to draw theFRG.

Using an Oval to Draw the FRG

Below I have added a circle to the reference grid. Notice that the circle just touches themidpoints of the sides of the square. These are called tangent points, and they are alsowhere the X and Y axes intersect the sides of the square. You should also notice that the Xand Y axes both mark the diameter of the circle.

To draw this foreshortened X-Y reference grid, we start by drawing an oval and finding itscenter using its major and minor axes. It might help to imagine drawing a rectangle that is justbig enough to fit the oval inside. In the image below, you can see the major and minor axes areparallel to the sides of the rectangle and intersect at its center.

Page 29: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Next, we will draw the Y axis. I always align the fuselage with the Y axis in this book.This line simply needs to cross the center of the oval. The direction that it is drawn is entirelyup to the artist and should be based on how you want the final drawing of the plane to beoriented. In the image below I have drawn the Y axis, but as you can see, it is not clear howwe should draw the X axis.

Recall that if we draw two lines parallel to the Y axis, we can use the tangent points toget our X axis correctly aligned. The next image shows you what I mean.

Below I’ve added all four sides of our foreshortened square with the X and Y axesdrawn inside. You’ll also notice that I have drawn the Z axis. As it turns out, the minor axis ofthe oval tells us how to orient the Z axis. You can see our oval is getting more useful by theminute!

Page 30: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

All that is left to do is to draw some gridlines which will subdivide each axis into foureven parts. An easy way to do that is to draw diagonals to find the centers of each of the foursmaller squares created by the X and Y axes. Using those intersections, you can draw theminor gridlines as in the image below.

Below is our FRG so far. We have drawn the X-Y reference grid, and we know theorientation of the Z axis. Throughout this book I will use the X-Y reference grid for the top viewscaffold. The next thing we need to do is to add a reference grid for our side view.

As you may have already guessed, I use the Y-Z reference grid for the side view. Wealready have the Y axis properly foreshortened so all that is left to do is to figure out how toforeshorten the Z axis.

Page 31: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

How Long is the Z Axis?

Just like the X and Y axes, the Z axis needs to be foreshortened. The drawing on theleft below is an example of a Z axis that does not need to be foreshortened because it isalmost perpendicular to our point of view. The drawing on the right below shows a Z axiscoming towards the viewer, so it is foreshortened much more.

First, let’s consider a situation where the Z axis does not need to be foreshortened.Remember our pizza example above? The one line that wasn’t foreshortened was drawnalong the major axis of the oval. In other words, the length of the major axis of the oval is theunforeshortened length of each of our three Cartesian axes. The image below illustrates this.You can see that the Z axis is the same length as the major axis of the oval. Once again ouroval comes in very handy!

The good news is that in many cases, you won’t need to foreshorten the Z axis verymuch as long as you are drawing the airplane from a little above or below wing level. If you doneed to foreshorten the Z axis, I have some rules of thumb to help you.

Understanding the Aspect Ratio

My rules of thumb for foreshortening the Z axis are based on something called theaspect ratio of the oval. The aspect ratio describes the ratio of the length of the major axis tothe length of the minor axis. The aspect ratio is written as two numbers separated by a colon.For example an aspect ratio of “3:1” is read “three to one” and it means that three minor axesare equal to one major axis. The oval in figure below has a 3:1 aspect ratio.

A high aspect ratio oval is one in which the major axis is many times the length of theminor axis, like 6:1. A low aspect ratio oval is one in which the minor axis is almost the samelength as the major axis, like 1.25:1. This is illustrated in the figure below.

If you think of the ovals in the image above as oblique circles, you can see that as yourpoint of view moves higher above the circle, the aspect ratio of the oval decreases (When anoval represents a circle drawn in perspective, I will call it an oblique circle in the remainder ofthis book). As the aspect ratio gets smaller (closer to 1:1), the Z axis gets smaller too (moreforeshortened). In the next section I will show you how the aspect ratio and the length of the Zaxis are related.

Aspect Ratio and the Foreshortened Z Axis

Take a look at the figure below and imagine what it would be like to view this object fromthe side and front. Both the “side view” and the “front view” people will see oblique circle A asa straight line (see the thought bubbles in the figure below). Now, imagine how they will seeoblique circle B (containing the Z and Y axes). The side view person will see oblique circle Bas a circle, but the front view person will see it as a straight line. Now imagine that we rotatethis object around the X axis in the direction of the arrow. As we do that, the front view personwill see oblique circle A as an oval with a steadily decreasing aspect ratio and a foreshorteningZ axis. The next several images illustrate what I’m talking about.

In the image below the object was rotated around the X axis in the direction of thearrow. You can see what our side view person would see and what our front view personwould see. In this case, the front view person would see an oval with an aspect ratio of 6:1.Notice that at this aspect ratio, the Z axis is hardly foreshortened.

Page 34: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

If we continue to rotate the object around the X axis till the front view person sees anoval with a 4:1 aspect ratio, the Z axis will have only foreshortened about 5%.

Rotating until the front view person see an oval with a 2:1 aspect ratio, the Z axis is onlyforeshortened about 15% as you can see below.

Page 35: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Rotating till the front view person sees an oval with a 1.5:1 aspect ratio foreshortens ourZ axis by about 25%.

In the final example, with the front view person seeing a circle with a 1.25:1 aspect ratiooval, the Z axis is foreshortened to about half its original length

Page 36: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Three Simple Rules for Foreshortening the Z Axis

My guess is that this section has put your artist vision to the test. Hopefully it all makessense to you. Just try to remember three easy rules of thumb.

1. Most of the time, the Z axis will only need to be foreshortened a little.

2. The Z axis won’t be noticeably foreshortened until the oval is at an aspect ratio of about2:1. Even then, we only need to shorten the Z axis by 15%.

3. The Z axis doesn’t dramatically foreshorten until Oval A is very close to being a circle (e.g.,an aspect ratio of 1.25:1).

Adding the Z Axis to the FRG

Picking up from where we left off, you can see our oval has an aspect ratio of about 3:1in the image below, so we will have to foreshorten the Z axis by about 10%. Recall that theside view reference grid only needs to be one grid square above and below the Y axis.

One quarter of the major axis of the oval is equal to the unforeshortened side of onegrid square. So, I have to measure that distance on my Z axis and then foreshorten it by 10%.I use a square (drawn with dashed lines in the image below) with sides equal to one quarter ofthe major axis to help me measure this. Next, I draw a mark that is about 10% below the topof that square to add the right amount of foreshortening.

Page 37: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

By drawing lines parallel to the Y and Z axes, I can now complete the side viewreference grid as in the image below.

Summary

How you draw the FRG determines the point of view from which your plane will bedrawn. The FRG also insures all the parts of the airplane are properly aligned andforeshortened in the final drawing. If you found this lesson confusing, just practice drawing acouple of FRG’s yourself and it will start to come together.

In the next lesson, we are going to add perspective to our FRG. You will see thateverything I have told you about the FRG in this lesson still holds true when you addperspective.

Lesson 5: Drawing the FRG in Perspective

The Oval in Perspective

The image below is a reference grid drawn in perspective. As you can see, this does notlook like the reference grids we’ve been drawing so far. In this lesson I’m going to show youhow to use the oval to help draw the FRG in perspective. Before I do that, however, I want totalk about how perspective affects the “zoom” level of an image.

What is Perspective?

The picture below is a classic American landscape. Elementary art teachers use thislandscape to illustrate how perspective works. The principle is quite simple. Parallel lines willconverge at a point on the horizon, just as the railroad tracks do.

Another principle of perspective is that things get smaller as they get farther away.Notice the how the railroad ties (the “ladder rungs” that cross the tracks) get shorter and closertogether as they approach the horizon.

Page 39: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Drawing with Perspective Lines

The picture below uses these two principles to draw a grid on the ground. The pointwhere all parallel lines meet is called a vanishing point which is on the horizon. Normally, thehorizon is where the land and the sky meet, but for perspective drawing it is better to think of itas eye level. For example, if you were looking straight up at the sky, the principles ofperspective would work the same way even though you wouldn’t be looking at the horizon ofthe earth’s surface.

We can also use perspective lines to draw three dimensional shapes. The picturebelow shows how you might draw a cube using vanishing points. Because there are twovanishing points, this is called two point perspective. The two vanishing points are 90° apartbecause they align with the sides of a square.

If we were above the cube looking down, you could imagine that all the parallel lines ofthe cube would have different vanishing points. Below you can see that a cube has three setsof parallel lines (corresponding to the X, Y, and Z axes). Because each set has a differentvanishing point, this is called three point perspective.

Page 40: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

You can probably already imagine how we can use vanishing points to add perspectiveto the FRG, and I will get to that shortly. Before we look at how to add perspective to the FRG,however, I want to show you how perspective can affect a drawing.

Using Perspective to Draw an Airplane

Let’s take a look at what a simple airplane scaffold would look like if we drew it using avanishing point and horizon. The wings and tail are parallel to each other, so we know thoselines will go to a single vanishing point. The picture below shows us how it might look.

YIKES! That looks a little strange. It almost looks like the plane is bent in the middle.The wings are going one way and the tail is going another way. So what happened? We usedour principles of perspective correctly, didn’t we?

Page 41: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Even though we did everything right, it looks funny. Take a look at the drawing belowand you’ll see the same issue. Everything looks bent and warped. Why do you think that is?

Human Central and Peripheral Vision

To understand why using perspective lines can make things look bent when they shouldbe straight, you have to understand how we visually perceive the world. Right now, you’refocusing on this page, but you can also see things around you. In fact, you can probably seethings that are way off to the left and right of your head without even moving your eyes. Take aminute to notice the difference between what you “see” when you look directly at something,like the words on this page, and what you “see” to the left and right of your head.

You should have noticed that you see a lot more detail when you look directly atsomething. This part of your visual field is called your central vision, and it is where you haveyour greatest visual acuity. Everything around your central vision is your peripheral vision.

To get an idea of the size of your central vision, try fixing your gaze at the dot in thestring of letters below. Without moving your eye (you’ll have to really concentrate to do that),see how many letters around that single dot you can clearly see.

nmlkjihgfedcba•abcdefghijklmn

At a distance of 18 inches (a normal reading distance), your best acuity is a circle 0.3inches diameter (between the “b” and “c” on either side of the dot). You can see with fairacuity to a circle with a 1.5 inch diameter (out to the “f” on each side of the dot). Beyond that,your acuity drops off dramatically in your peripheral vision. Remember, you can still see what isin your peripheral vision, you just can’t see in much detail.

To give you an idea of the size of your central and peripheral vision, look at the diagrambelow. It shows the visual field for the right eye as seen when looking straight down from thetop of someone’s head (the nose is pointing towards the top of the page). The clearest part of

Page 42: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

your central vision is actually only about 1°, but you can see fairly well out to about 5°. Yourperipheral vision extends 60° towards your nose and 100° towards your ear.

Are you surprised at how small your central vision is? The reason we don’t notice ourcentral vision is so small is that our eyes constantly move around when we look at the world.Most of the time, our eyes move automatically. This is why you had to concentrate to keepyour gaze focused on that dot.

Drawing with Perspective Lines the Right Way

Have you ever seen artists or photographers hold their hands up to make a box in frontof their faces? Now that you understand central and peripheral vision better, you canunderstand what they are doing. They are blocking out some of their peripheral vision. Theydo this because it helps them frame a part of the scene that they want to paint or photograph.

Let’s go back to our perspective drawing and see what this might look like. The framebelow shows you what happens when you block off some of your peripheral field of view.Notice that the perspective lines don’t spread out as much within that frame.

Page 43: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Zoom vs. Wide Angle Views

Most digital cameras have the ability to zoom in and out. Did you also notice that whenthey zoom in, they cut off more of a scene? Now that you understand perspective lines, youknow that this means perspective lines spread out less and less the more you zoom in. Thepicture below shows you what I’m talking about. The zoom frame (the small, inner one) showsyou what your camera would capture if you zoomed in more. The wide angle box shows youwhat your camera captures when zoomed out. Notice that in the wide angle box, theperspective lines converge much more than in the zoom frame.

When we look at the world, even though we perceive a very wide angle, we primarilyfocus on a very small area in the center of our field of view. In other words, we normally don’tsee sharply converging perspective lines. This is partly why it can look strange when we try tocapture really wide angle views in a camera or in a painting - like the drawing of the cockpit

Page 44: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

above. That doesn’t mean that you shouldn’t draw pictures using a wide angle view. Allpictures have some degree of zoom. So, let’s take a look at some drawings to see how zoomand wide angle views differ from each other.

Below is a drawing of an F-16 using a wide angle view. I have added some gridlines sothat you can see how much the perspective lines converge.

The drawing below is a zoomed-in view of an F-16. Notice that the perspective lines inthe reference grid don’t converge as much as in the wide angle view. What differences do yousee between these two drawings? You should notice that in the wide angle view above, the tailis much smaller relative to the nose than in the zoomed-in view below. Although the wideangle view is more distorted, it gives the impression of being much closer to the aircraft.

Here are a couple examples of the A-10 Warthog, one of my favorite aircraft. Youshould be able to tell that the first drawing below is a wide angle view.

Page 45: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Just as with the F-16 drawings, the nose is much larger than the tail. This gives you thesense that the nose is looming in front of you. Contrast that with the zoom view below. In thewide angle view, you feel like you are standing only a few feet in front of the A-10, but in thezoom view, you get the sense that you are standing much farther away.

Zoom views look less distorted and wide angle views can make things look closer to theviewer and more three-dimensional. Which one you choose to use depends on the story orfeeling you’re trying to convey in your picture. When you look at photographs or paintings ofplanes (or anything for that matter) see if you can pick out the perspective lines and notice howthey affect the way the picture looks.

Now that you understand the concept of perspective, and how it relates to the “zoom”level of the image, we can discuss how to draw the FRG in perspective.

Page 46: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

The Oval in Perspective Part II

Let’s look at how we would draw our FRG in perspective. To review, the image below isa FRG drawn using the process I showed you in lesson 4.

Now compare the drawing above to one drawn using a wide angle perspective below.Notice that the tangent points of the square still show us where the X and Y axes intersect theoval.

In the image below I have drawn the major and minor axes of the oval in dashed lines.Notice how the center of the oblique circle is different from the center of the oval. This is one ofthe effects of perspective. As things get farther away from us they get smaller.

Page 47: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Remember the railroad tracks that were drawn in perspective? The ties of the railroadtracks get closer together as they recede into the distance. Below you can see that an oval isstill a useful tool for helping us determine how to draw a FRG in perspective.

Now take a look at the zoomed view of a reference grid in perspective below. As youcan see, the lines converge less. You can also see that this causes the center of the obliquecircle and the center of the oval to be much closer together.

Page 48: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Below you can see how the railroad tracks would look using a zoomed view. Thevanishing point is much farther away, outside of the boundary of the drawing.

Drawing the Reference Grid in Perspective

Below is an example of a FRG drawn using two point perspective. As you can see, thiscreates a very wide angle view. In fact, most of the time when you have all your vanishingpoints within the frame of your picture, you will have a wide angle view.

Page 49: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Because some or all of the vanishing points may not be inside of the frame of a drawing(especially for zoom views), the next section will show you a method for drawing the FRGwithout needing to find vanishing points.

A Method for Drawing the FRG

In the first step, draw an oval and its major and minor axes. Then choose an interceptpoint on the minor axis. The further this is from the major axis, the more you will produce awide angle view. In this example I will draw a zoomed in view. Once you have chosen thatpoint, draw a line through it. This will be the Y axis.

In the second step, draw lines that are tangent where the Y axis intersects the oval.

Page 50: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

In the third step, you will draw the X axis line so that it crosses the Y axis at theintercept point. You will have to use your artist vision to estimate the alignment of the X axisbetween the other two lines.

In the fourth step, draw lines that are tangent where the X axis intersects the oval.

Page 51: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

In step 5, we will add additional gridlines. Just as we did in the previous lesson, we candraw diagonals across the four squares to find their centers.

Diagonal lines are also useful to check that you have everything aligned correctly. If thelong diagonals of the reference grid don’t cross at the same point as your X and Y axes, thenyou need to adjust the alignment of the edges of your FRG. Don’t worry if they don’t coincideperfectly. As long as the diagonals cross close to the X-Y intercept point, you’re final drawingwill look great.

In step 6, we add the minor gridlines, just as we did in the previous lesson. Notice howthey converge a little bit due to perspective.

Page 52: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Drawing the Z axis

In step 7, we draw the unforeshortened Z axis just like we did in lesson 4. The onlydifference is that we have to measure from the center of the oblique circle, not the center of theoval. This is illustrated in the image below. Recall that one grid square is one quarter of thelength of the major axis.

In step 8, foreshorten the Z axis using the rules I showed you in lesson 4. In this casethe oval is about a 3:1 aspect ratio so we will foreshorten about 10% as illustrated below.

Page 53: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

In step 9, I have drawn the top and bottom gridlines of the side view reference grid.Remember, they are parallel to the Y axis. By using the gridlines in the top view FRG, it is easyto estimate convergence of the top and bottom gridlines of the side view FRG.

In the final step, I have added lines to enclose the side view reference grid. These aredrawn parallel to the Z axis. I’m drawing this with two point perspective, so I won’t worry aboutconvergence of these lines. Because this is a zoom view and because the Z axis is nearlyperpendicular to our point of view, there isn’t enough convergence of these lines to make itworth the effort to use three point perspective.

Page 54: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Below is my completed FRG. I have just filled in the minor gridlines on the side view (Y-Z) reference grid.

Convergence of Lines around the Z axis

There are some instances when you will need to account for convergence of the Z axis(i.e., three point perspective). The main reason, as you may have guessed, is when you use awide angle view for your drawing.

One way to visualize convergence of lines parallel to the Z axis is to add smaller ovalsinside of the top view FRG. The minor axes of those ovals will reveal the amount ofconvergence around the Z axis. This is shown in the images below. In the first image below,there is very little convergence of those lines because this is a relatively zoomed in view.

Page 55: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Below is a wide angle view. Notice how much more the lines parallel to the Z axisconverge as compared to the image above.

Below is another example of convergence with a wide angle view below.

Page 56: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

In the zoom view below, convergence of the lines parallel to the Z axis is hardlynoticeable.

The bottom line is that when using a zoom view, there really isn’t enough convergenceof the Z axis to worry about. For those cases you can use two point perspective. When usinga wide angle view, you might need to use three point perspective, especially for lower aspectratio ovals.

Summary

This was a long lesson and I hope it doesn’t seem too overwhelming to you. Although Igave you a lot of steps to follow, don’t feel like you have to memorize them. I have describedall of these steps to make it easier for you to understand. With practice, drawing a FRG willbecome second nature. In the end, it is more important to have an understanding of howperspective works and how it influences your final drawing than it is to memorize a bunch ofsteps.

Now that you can draw a FRG in perspective, we are ready to move on to the next stepwhich is transferring our scaffold to the FRG.

Lesson 6: Transferring the Scaffold andAdjusting it Using Projection

Introduction

In this lesson I am going to show you how to transfer the scaffold to the FRG (step 3)and how to adjust it using projection (step 4). Transferring the scaffold is just a matter of usingthe top and side view scaffolds we created to draw corresponding lines on the FRG.Projection is used to move some parts of the scaffold out of the planes of the top or side viewFRG when necessary. Let’s keep developing our Spitfire and Sabre Jet examples and you willsee what I am talking about.

Review of the Spitfire Scaffold

Take a minute to review the top view scaffold of the Spitfire below and the estimates forthe location of the lines. Though you may be tempted to take out a ruler and actually measurethese distances, you really don’t need to. The final drawing will look great just usingestimates.

Below is the side view scaffold for review.

Page 59: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Step 2: Drawing the Spitfire FRG

I’m going to draw the Spitfire from above looking down with the nose of the airplanepointing to the right. In my FRG below you can see that my oval has an aspect ratio between2:1 and a 1.5:1. Because of this, I need to foreshorten my Z axis by about 20%. This will be arelatively zoomed in view so I have done this using two point perspective.

Step 3: Transfer the Spitfire Scaffold to the FRG

Next, I transfer my scaffold onto the FRG. The image below shows how I haveestimated the locations of its parts. The gridlines in the FRG make it pretty easy. This iswhere a simple scaffold really pays off. The top view is in the X-Y plane and the side view is inthe Y-Z plane. Next, we will project the wings and tail into position.

Step 4: Adjusting the Spitfire Scaffold Using Projection

Although I don’t need to create a front view scaffold, I have drawn one here to make iteasier to see how the wings and horizontal stabilizer will need to be projected. Below is thefront view of the plane on a reference grid.

Below you can see how we will project the center of the wings to the bottom of thefuselage and we will project the scaffold for the horizontal stabilizer up about 1/8 of a square.

Page 61: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Below you can see how I have projected the wings and horizontal stabilizer on myFRG.

Below is the finished scaffold and FRG for the Spitfire.

Review of the F-86 Sabre Scaffold

Next, let’s look at how we would transfer the F-86 Sabre scaffold. Below are the topand side view scaffolds that we created in Lesson 3.

Below is the side view scaffold.

Page 63: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Step 2: Drawing the F-86 FRG

I’m going to draw the F-86 coming towards the viewer using a wide angle perspective.The viewpoint will be slightly above the jet. My top view scaffold is below.

The oval is about a 3:1 aspect ratio so we will foreshorten the Z axis by about 10%.Even though this is a wide angle view, I use two point perspective to draw this FRG since the

Z axis is almost perpendicular to our point of view, as you can see in the image below.

Page 64: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Step 3: Transferring the F-86 Scaffold to the FRG

Below I have drawn the lines of the scaffold using the corresponding gridlines in myFRG. By using straight lines for the scaffold, I can quickly draw it by estimating key locationson the scaffold.

Step 4: Adjusting the F-86 Scaffold Using Projection

Take a look at the front view of the Sabre below. The X-Y plane is above the wings andbelow the tail, so I will need to project the wings down and the tail up a bit.

The image below shows you how much everything needs to be projected. Notice thatthe wings have a little dihedral so the center is projected down more than the wingtips. Thehorizontal stabilizer also has dihedral. I only need to project the ends of the horizontalstabilizer scaffold up.

Page 65: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Below you can see how I have adjusted the scaffold on the FRG.

Below is my finished F-86 Sabre scaffold.

Summary

We have now covered the first four steps of the process for drawing airplanes: creatinga scaffold from a 3-view drawing, drawing a FRG, transferring the scaffold to the FRG, andusing projection to adjust the scaffold.

At this stage, the scaffold should be starting to give you an idea of what the finisheddrawing will look like. In the next step, the final drawing will really begin to take shape (hint,hint).

Lesson 7: Outlining and Shaping

Introduction

In this lesson I am going to show you how to do steps five and six of this seven-stepprocess. These steps entail outlining and shaping the fuselage, wings, and tail of the airplaneresulting in a drawing like the one below.

Step 5: Outlining and Shaping the Spitfire Fuselage

The first thing we need to do is to draw the outline of the fuselage using the scaffold.The drawing below shows what this looks like. You will need to refer to the side view drawingon the reference grid to draw it accurately. You can see that I have used my scaffold referencelines to make sure everything is in the correct position.

Page 68: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

The Spitfire is challenging to draw because it has a lot of curved lines. As your artistvision grows stronger, you will be able to visualize and draw curved lines using the scaffold onthe FRG, but if you are having trouble, there is a simple trick you can use. Draw a grid insidethe part of the scaffold that is giving you trouble then note where the outline of the 3-viewdrawing crosses the lines of the grid.

Look at the image below and you can see how I have done this for the vertical stabilizerin the tail. The dots indicate where the outline of the stabilizer crosses the lines in my grid.

Next, draw the same grid on the scaffold in the FRG then mark the correspondingpoints. You should be able to connect the dots and draw the outline accurately.

Page 69: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Next, I draw an outline of the top view. Since it is drawn with straight lines it isn’t toohard to do.

Shaping the Fuselage: Drawing the Cross-Sections

To shape the fuselage correctly, we have to examine the cross-sections of the fuselage.These cross sections are also called bulkheads. Below are some examples of different typesof bulkheads.

Page 70: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

As you can see, fuselage bulkheads can have many different shapes. To make matterseven more complicated, in most airplanes, no two bulkheads are the same.

Below you can see the bulkheads of the Spitfire. I have not drawn every singlebulkhead in the actual aircraft. For this drawing we just need to draw enough to get an idea ofthe shape of the fuselage.

To help me visualize the bulkheads, I draw crosses that mark the height and width of thefuselage where the bulkheads will be drawn. Each of the crosses is centered on the fuselagescaffold line. They are drawn parallel to the Z and X axes in the figure below.

Use your artist vision to visualize the shape of the bulkheads using the crosses in thefigure above. If you are having trouble, remember you can use the same trick I showed youearlier. Start by drawing a grid around the bulkheads in the 3-view drawing and note where theoutlines cross the grid lines.

Page 71: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Next, add the grids to the FRG using the crosses as a reference.

Then draw the bulkheads using the grids as a reference.

Shaping the Fuselage: Drawing the Silhouette

The final step in shaping the fuselage involves drawing the silhouette of the fuselage.Using the inflection points of the bulkheads, I can visualize the edges of the fuselage frommy point of view. I just have to connect the dots using those points. The inflection points are

Page 72: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

the places where the bulkhead shapes change direction. The arrows below show you theinflection points.

Below I have drawn the silhouette around the nose. You can see how I have connectedthe dots so to speak. You will also notice that I had to use my artist vision to judge thecurvature of the silhouette in some places. A plastic model and/or some referencephotographs are very helpful for getting the silhouette just right.

Below you can see the silhouette for the entire fuselage. In the tail section, the outlineand the silhouette are almost the same. The bottom edge of the fuselage does extend a littlebelow the fuselage outline from our point of view.

Page 73: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Step 6: Shaping the Spitfire Wings and Tail

Once you have shaped the fuselage, shaping the wings and tail is a piece of cake. Youfollow the same steps that you did to shape the fuselage. First draw the outline of the wingsand horizontal stabilizer and then draw the cross-sections or airfoils. From our point of view,the silhouette of the wings and tail will be the same as the outlines.

The Spitfire’s wings and tail are tricky to draw because they are elliptical. This meansyou have to visualize the foreshortening of curved lines. This is a good time to use the gridmethod if you are having trouble transferring this shape to the FRG. Below I have drawn a gridfor the horizontal stabilizer.

And in the image below, I have used this grid to draw the horizontal stabilizer on myFRG. It is definitely easier to do this way.

Page 74: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

If necessary, do the same thing to draw the outline of the wings. Below you can see theoutline of the wings and horizontal stabilizer. Our Spitfire is coming to life.

Shaping the Wings and Tail: Drawing the Airfoils

The cross section of the wing and tail is called the airfoil. There are many differentkinds of airfoils and each one has advantages and disadvantages. Below are examples ofsome different types of airfoils. The first example below is a Flat Bottom airfoil. These havecurved upper surfaces and flat bottoms. You will see these airfoils on many private aircraft.They produce a lot of lift without producing too much drag.

Page 75: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

The second example below is a Deep cambered airfoil. These produce more lift thanflat bottomed airfoils at low speeds, but they produce much more drag. The Wright brothersused this style of wing as did most early airplane designers.

The third example below is a Flat Bottom Airfoil with Flaps. Flaps are most commonon the trailing edge of wings, but they can also be on the leading edge. Swept wing jetsusually have leading edge flaps. When the pilot lowers the flaps, the wing functions like adeep cambered airfoil. This allows it to fly slower without stalling during takeoff and landing.

The fourth example below is a Symmetrical airfoil. These airfoils produce less drag butdon’t produce lift at a zero degree angle of attack as other types do. They do have theadvantage of performing the same when the plane is flying right side up or upside down. Thismakes this airfoil ideal for planes that need a lot of maneuverability and speed, like jet fightersor stunt planes.

The final example below is a Semi-symmetrical airfoil. These are a blend betweensymmetrical and flat-bottomed airfoils.

Shaping the Wing and Tail: Drawing the Spitfire Airfoils

The Spitfire wings have a semi-symmetrical airfoil. Since we are viewing it from above,we only see the upper surface of the wing, but I have drawn the whole airfoil so that you canvisualize what it would look like. First, draw simple reference lines at equal intervals alongeach wing as I have done below.

Page 76: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Next, draw the airfoils along the reference lines as in the image below.

You can do the same for the horizontal and vertical stabilizers. As you can see below,these both have symmetrical airfoils.

Page 77: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

It is important to note that these shaping lines are only to help you visualize the shapeof the wings and fuselage. Most of them are not going to remain in the final drawing. Below Ihave cleaned up my drawing so that only the foreground lines are showing. The airplane hastaken shape.

Step 7: Clean up and Final Details

The true shape of the final aircraft is conveyed by the panel lines, shading, andmarkings on the aircraft. Below is my final sketch showing a Spitfire with markings of no. 118Squadron. It was stationed at Ibsley in the U.K. and was flown by Pilot Officer Alec S.C.

Page 78: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Lumsden. I’ve done a lot in this step, but you can see how it is all built on the shaped drawingthat I completed above.

Step 5: Outlining and Shaping the F-86 Sabre Fuselage

In this section I’ll demonstrate how to outline and shape the F-86 Sabre. I’m going tomove through the steps a little faster since you are now familiar with these techniques. Belowyou can see my side view outline of the F-86 fuselage. By observing my scaffold references, itis not difficult to draw.

Page 79: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Next, I add the top view outline. Below you can see I drew a couple of dashed lines tohelp me draw it to the correct width. Remember you can use the grid technique to help you ifyou need to.

Now we’re ready to add the bulkheads to determine the shape of the fuselage. Theimage below shows you the shape of the bulkheads along the Sabre’s fuselage. The F-86 hada wide body because the engine was housed inside.

Page 80: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Below I have created some reference boxes to help me draw the bulkheads correctlyjust as I did with the Spitfire fuselage.

Below I have drawn the bulkheads. The boxes help me to get the size and shape of thebulkheads right.

Page 81: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Next, I draw the silhouette. The inflection points of the bulkheads are indicated witharrows below. I used reference photographs to help me estimate the curvature of the fuselagebetween the inflection points.

Below I have added the canopy and engine intake. It’s starting to look like a Sabre Jet!

Page 82: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Step 6: Outlining and Shaping the F-86 Wings and Tail

The Sabre’s wings and tail have straight edges making them much easier to draw thanthe Spitfire’s. The wings have semi-symmetrical airfoils, but since we only see the uppersurfaces, I have only drawn the curvature for that surface as you can see in the image below.

Below you can see my fully outlined and shaped drawing of this iconic jet fighter.Remember the bulkhead and airfoil lines are only there to help me visualize the shape of theairplane. They won’t appear in the final drawing.

Step 7: Clean up and Final Details

Adding light, shadow, reflections, and markings are what ultimately convey the trueshape of the airplane we are drawing. In my final sketch below, I have drawn the F-86 flown

by Major James Jabara of the 334th fighter squadron, stationed at Kimpo Airbase during theKorean War. Major Jabara was the first U.S. jet ace. Not only that, he finished the war as atriple Ace!

Summary

Okay Grasshopper, you should now have an understanding of the first six steps I use todraw airplanes. In many ways the first six steps are technical. The last step, adding all thefinal details, is a step that requires all your skills as an artist. The remaining lessons of thisbook focus on teaching you the artistic skills you need to draw realistic airplanes.

Lesson 8: Drawing the Piper Cub

Putting it All Together

In this and the remaining lessons, I will show you worked examples from start to finishwith a focus on the final step. The final step will make or break your drawing. There is more togetting it right than in all of the other steps combined.

In this lesson we’re going to draw the J-3 Piper Cub. The J-3 was first built in 1938 asan affordable private plane. It has a high wing which makes it easy to fly and it is designed toland and take off from grass airstrips. During the Second World War, thousands of Army pilotswere trained in the Cub. The Cub even saw service in WWII as the L-3 observation plane.The Piper Cub is one of the most popular airplanes ever built and many versions are stillproduced today. Below is a 3-view drawing of this famous little airplane.

Page 86: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

A Closer Look

Before we begin to draw the J-3 Cub, we need to do a little homework. Drawing anyairplane correctly requires that you understand its form and function. I always find that themore I study an airplane I am drawing, the better I can “see” it. At first glance, I often overlooksmall details or may even misinterpret the shape of some component of the airplane. After Ispend some time reading about its design and studying drawings and photographs, I amalways much better prepared to do my own drawing.

The Piper J-3 cub is built primarily of welded steel tubing and is covered with canvas.Because of this, there are no rivets or seams as is the case on modern, metal-skinned aircraft.The stretched canvas tends to reveal the underlying framework. In the 3-view drawing, mostof the lines represent places where the frame is visible as a ridge or bump under the canvasskin. For example, in the top view you can see the lines where the wing ribs are visible. Analuminum sheet covers the leading edge of the wing, so the rib lines are only visible behind thesheet.

A system of pulleys and cables transmit the Pilot inputs on the stick and rudder pedalsto the control surfaces. Those control cables can be seen where they pass through openingsin the canvas to connect to the aileron and rudder horns. You can’t see any cables for theelevator because they are concealed inside the vertical stabilizer.

The J-3 Cub is powered by several different engines and almost all of them are in a“flat-four” configuration. That is, four cylinders, two on each side, all in the same plane. In thetop view you can see that the cylinders are actually offset slightly. The left side cylinders areslightly in front of the right side cylinders. That was done so that the pistons can each attach toa different point on the crankshaft. The cylinder heads extend out of the nose cowling giving

Page 87: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

the J-3 one of its most distinguishing characteristics. These engines produced between 40 –65 horsepower.

In the top view above, you can also see the small skylight located between the twowings. In military versions of the Cub, built during WWII, the skylight was enlarged to span theentire space between the wings. It also extended behind the wings, as did the side viewwindows. If you see a Cub with a skylight that covers all the space between the wings, it isprobably a military plane that was converted back into a civilian Cub.

Looking at the front view of the Cub above, you can see that this is an aerodynamically“dirty” plane. By that I mean that it has a number of struts and wires, not to mention its landinggear, all of which create a lot of drag. For this reason, the Cub does not need flaps to slowdown on landing.

If you look carefully at the front view, you can see that there is some wing dihedral.According to the service manual for the Cub, a string stretched between the two wingtipsshould pass about 2 3/8 inches above the center of the fuselage. Admittedly, that’s not a lot ofdihedral. It becomes slightly more pronounced in flight because the wings are notcantilevered. Instead, they attach to the fuselage and are supported by wing struts.

The Cub has a simple suspension system. The main wheel struts are attached to thefuselage by hinges. These are held in position by telescoping struts that are held closed by abungee cord. This allows the wheels to spring outward a little bit when the plane lands,helping to cushion the landing. The bungee cord is covered by black canvas or vinyl covers.Because of the way the suspension works, the wheels are spread apart a little further on theground than they are in the air. In our front view, the wheels are shown in an in-flightconfiguration. On the Cub wheel brakes are optional. The plane lands at about 35 knots andwith a slight headwind, rolls to a stop very quickly. Being a tail-dragger, brakes can be ahazard. Applied too strongly, the plane will flip onto its back. This version is drawn withoutwheel brakes, but in many photos you will see brake lines extending under the fuselage tobrake drums on the wheels.

The Cub has a 9 gallon fuel tank just behind the engine. To counterbalance this weight,the pilot sits in the rear seat. This keeps the center of balance under the wings. Whendrawing the J-3 Cub in flight with only the pilot, make sure you put him in the right place! Laterversions of the Cub, including the military version of the J-3, moved the fuel tanks to the wings

Page 88: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

so that the pilot could sit in the front seat. The fuel gauge is simply a graduated stick thatpokes through a hole in the fuel tank cap. The bottom of the stick has a floater so that as thefuel is used up, the graduated stick moves down. By looking through the windscreen at themarks on the stick, the pilot can determine how much fuel is remaining.

The control cable for the ailerons runs from the bottom of the fuselage through eyeletsalong the back of the forward wing strut. At the top of the strut is a small exposed pulley. Thecable loops around the pulley then goes up through a hole in the canvas on the bottom of thewing and exits on the top of the wing to attach to a control horn on the aileron. There is also acable attached to a horn on the bottom of the aileron. That cable wraps around a pulley insidethe wing and extends all the way across the wing to the opposite aileron. This links theailerons so that they always move in opposite directions.

While most aircraft have trim tabs embedded in control surfaces, pitch trim in the Cub isaccomplished by elevating or lowering the leading edge of the horizontal stabilizer. A smallslot in the fuselage allows for this movement (see side view above). Pitch is adjusted bymeans of a crank in the cockpit. While we’re looking at the tail, you might notice that the wirebraces in the tail are not perpendicular to the fuselage. They attach to the horizontal stabilizerjust in front of the elevator and attach to the vertical stabilizer in front of the rudder. Becausethe elevator hinge is in front of the rudder, the cables are angled forward just a bit.

You may be wondering how the pilot entered the Cub. There is no door in our side viewafter all. As you might have guessed, the door is on the right side of the airplane. Since ourside view is of the left side, we can’t see it. Just something to keep in mind should you decideto draw the Cub from the right side.

At first glance the Cub appears to have a rectangular fuselage. In fact, if you look at thecross-sections below you can see that it is not a simple rectangle. A spar along the uppercenterline forms a ridge that extends from the skylight all the way back to the verticalstabilizer. The side of the fuselage from the wing to the tail is divided into three planes by twospars. This gives the sides of the rear fuselage a slightly convex shape. The bottom of thefuselage is flat. In the nose, the sides and bottom are flat with rounded edges and the top isrounded. The tip of the nose is rounded.

Page 89: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Hopefully this closer look has helped you to “see” the Cub better. Even a simpleairplane like the J-3 Cub requires careful analysis to render it accurately.

If you are like me, you love drawing airplanes because you love everything about theseamazing vehicles. Learning more about them not only helps you to execute a better drawing, itis fascinating in its own right. No matter how many times I have drawn a plane, I often find thatthere is something new to learn about it, so don’t ever get complacent in your knowledge of aplane and its history. Always do a bit of homework before beginning any drawing. After all,what could be more fun than studying and learning more about the airplane you are going todraw?

Okay, with our homework done, we are ready to start our drawing.

Step 1: Draw a Scaffold based on a 3-View Drawing

Below is a scaffold drawn for the top view of the Piper Cub. This top view shows youthat the Cub has a wingspan that is almost twice the length of the fuselage.

Page 90: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Before doing the side view scaffold, take note of the true top of the fuselage.Remember the wings have a little bit of dihedral, that means that the tops of the wings in theside view are just above the top of the fuselage. The drawing below shows you the wing airfoilwhere the wing joins the fuselage.

Below is our side view scaffold.

Step 2: Draw the FRG

Next, I draw my FRG. The Z axis is foreshortened about 10% for this aspect ratio.

Page 91: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Step 3: Transfer the Scaffold to the FRG

Below is the transferred scaffold.

Step 4: Use Projection to Adjust the Scaffold

Below I have projected the wing and horizontal stabilizer into position. I have alsodrawn the wing airfoil to show you that the scaffold shows us where the bottom of the wingshould be – almost.

First, we need to add a little dihedral. This is shown in the image below.

Page 92: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Below is the finished scaffold. It may not look much like a Piper Cub now, but it willwhen we are done.

Step 5: Outline and Shape the Fuselage

Using my side view, I draw the outline for the fuselage on the FRG below. Most of thelines in the Piper Cub are straight, so it is just a matter of finding key reference points and thenconnecting the dots.

Page 93: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Next, I draw the outline of the top view. The outline follows the top view scaffold prettyclosely. The only difference is that the nose section narrows a little more than my scaffold andis rounded at the front as you can see below.

Below I have drawn some cross lines and rectangles to help me visualize the fuselagebulkheads.

Page 94: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Below are the fuselage bulkheads.

Now we are ready to draw the fuselage silhouette. If you study the side view drawing,you will notice that the two spars that form the top corners of the fuselage behind the wing,have a slight bend. To draw them, I start by drawing two straight lines as you can see in theimage below. Next, I make two small dashes to mark where they will bend.

Page 95: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Below I have redrawn the lines, bending them at the dashes.

Below is the complete fuselage silhouette.

Page 96: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Below are the two spars that run along the sides of the tail section of the fuselage.Later I will erase the parts of these that will be hidden by the wing and horizontal stabilizer.

All that is left is the cockpit, and the fuselage will be complete. To help visualize thecockpit, it might help you to draw a cube as I have done below.

Using the cube as a guide, I draw the outline of the cockpit windows as you can seebelow.

Below is the shaped fuselage.

Page 97: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Step 6: Outline and Shape the Wings and Tail

The arrows in the image below indicate where the curve of the wingtip touches thescaffold. This helps me to round off the wingtips accurately. Notice how the curve starts closerto the wingtip on the leading edge of the wing.

Below I drew lines to show me the location of the wing ribs (the ribs are shaped like theairfoil). I have only drawn reference lines for every other rib based on the 3-view drawing(there are 12 ribs on each side – I have drawn only six). I can fill in the missing ones in thefinal drawing.

Page 98: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Below I drew the tops of wing ribs. This gives my wing its shape. Remember we willonly see the tops of the ribs as ridges in the canvas covering.

I drew the vertical tail surface when I outlined the fuselage, so all I have to do is outlinethe horizontal tail surfaces as seen below. Remember you can draw a grid in the scaffold tohelp you get the outlines correct.

Page 99: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

The airfoils of the Cub’s vertical and horizontal stabilizers are flat. That means all Ireally need to do for my drawing is to draw lines where the spars are located. Below are thespars for the horizontal and vertical tail. If you look at photographs, you will notice the sparscan sometimes be seen through the canvas covering.

Step 7: Clean up and Final Details

Now that the wings and fuselage have been drawn and shaped, we need to add thefinal details like the wing struts, landing gear, propeller, and other details. Below I have drawnthe wing struts. Since the wing struts are below the wings, I will only be able to see parts ofthem in the finished drawing. I have drawn the complete struts here to make it easier tovisualize them.

Page 100: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

The struts are stabilized by braces, otherwise they would vibrate in the slipstreamduring flight. Below I have drawn the strut braces.

Next, I focus on the landing gear. I start by drawing some guidelines (see below).Notice how they are aligned with the fuselage bulkhead.

Page 101: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Below I have drawn the wheel struts and suspension.

All that is left is to draw the wheels. See the image below.

Page 102: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Below I have done a lot of clean-up and added details to the fuselage. We’re almostdone with the drawing!

I’ve finished up the details on the wings and tail below. At this point I compare myfinished drawing to photographs and make final adjustments. Depending on the quality of your3-view drawing, you may find that there are aspects of the plane that don’t quite look right.Hopefully, if you have been careful, you will be close enough that you will only need to make afew small changes. We’re not done yet though. We have to add shading and markings.

Sketching the Piper Cub

Below is the finished sketch I did based on my black and white drawing. As you cansee, this is where your homework pays off in helping you to get the shape right.

Page 104: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

In this sketch you can see how the shading provides the viewer with a lot of informationabout the three dimensional shape of the aircraft. If you look at the upper edge of the wing,you will see how shading and light convey the impression of the ridges created by the ribs thatare underneath the stretched canvas. Along the fuselage you will see the shadow created bythe wing and tail and the shape of the fuselage and engine cowling.

Shading, Light, and Reflection

Shading is not just a matter of making upper surfaces lighter than lower surfaces. Toreally get your shading right, you have to understand the way that light reflects off of objects.Take a look at the drawing of a shaded sphere below. The upper surface reflects what iscalled direct light. That is light coming directly from a source like the sun or a light bulb. Inmost cases, direct light will make a surface appear brighter.

On a sunny day or under a bright light, you will see a very bright spot of light calledspecular light (also called the highlight). The glint you see on a shiny surface is specularlight. The glossier or more reflective the surface, the more defined the glint or specular lightwill be. In our drawing above, the specular light is diffuse, so this is not a glossy surface.

Between the highlighted region and the shadow, you will see midtones. The midtonesreveal the true color of an object. They are not washed out by the specular light and they arenot hidden by the shadow. The shadow is not uniformly dark. In the case of our sphere, it hasa diffuse edge and you will also see indirect light reflected in the shadow. In the case of oursphere, the light surface on which it rests reflects off of the bottom of the sphere.

Compare the sphere above to the one below. The sphere below has a glossy (highlyreflective) finish whereas the sphere above has a matte (non-reflective) surface. Most aircrafthave a combination of matte and glossy surfaces so it is important to understand thedifferences in how light reflects off of these two surfaces.

Page 105: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

A matte finish is non-reflective, so the shadows will tend to be deeper and specular lightis diffuse. Military aircraft and vehicles are typically painted with a matte paint to hide thereflection of specular light. This makes them harder to detect. In contrast, a glossy finish hasmore subtle shadows and a bright, well defined specular reflection. In fact, glossy surfaces willalso reflect colors and shapes in the environment, much like a mirror. In the glossy spherebelow, you can see darker shapes and the lighter sky reflected as well as the light surface onwhich the sphere rests.

Glossy surfaces also reflect more color from the environment than matte surfaces. Ifyou look at a good photograph of an airplane painted with glossy paint, you will probably seeblue sky reflecting off of the upper surfaces and the earth below reflecting off of the lowersurfaces. Of course in a black and white pencil sketch you can’t show color, but you shouldstill be aware of how they are represented in a black and white drawing.

Now let’s take another look at the sketch of the Cub. The Cub has what would be calleda semi-gloss finish. That means that the shadows will be visible, but not too dark. Also it willreflect some lights and darks from the environment, but specular lights will be a little diffuse.

If you look at the upper surfaces of the wing in the drawing below, the darker regionsare not shadows, but rather reflections of the blue sky above. I have also tried to keep theshadows under the wing, fuselage, and tail subtle. Finally, if you look at the horizontalstabilizer, I have drawn a reflection of the vertical stabilizer. Without color cues, it is moredifficult to convey the appearance of a glossy finish, but you still have to be aware of how lightreflects off of the subject of your drawing.

The J-3 Grasshopper

Below is a drawing of the military version of the Piper Cub known as the J-3Grasshopper. It was covered with a matte, olive-drab paint. The J-3 was basically the sameaircraft as the civilian version except that it had a large “greenhouse” window which gave theobserver, seated in the back, an excellent field of view. Notice I have made the shadows muchdarker and I have minimized the appearance of specular light.

Below you can see the scaffold I used when doing this drawing. With practice, you willfind that you can keep your scaffold simple.

Drawing a Spinning Propeller

Drawing spinning propellers creates a feeling of action and motion in any drawing of anairplane, but drawing them can be challenging. There are many ways to draw a spinningpropeller and you will want to choose the one that best suits your drawing. Most aviationartists draw spinning propellers as they appear in photographs, which is not at all how theyappear to the naked eye. To the naked eye a spinning propeller is barely visible as a faintdisk. In a photograph the propeller is caught in motion, and so it appears blurry. Thisphenomenon is called motion blur.

To draw this motion blur correctly, it helps to understand why it occurs. A camera worksby exposing the film, or these days a digital sensor, to the image for a very brief period of time.It is so brief that most objects can’t change position, but a spinning propeller is going so fastthat it does.

Making things a little more complicated, the propeller moves further at the tip than at thebase. Take a look at the image below and you will see what I mean. This means that the tip ofthe propeller is moving faster than the base. Because of this, there will be more motion blur atthe tip than at the base.

Page 108: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

To draw this, imagine a wedge shaped area around each blade of the propeller as in theimage below on the left. That is the area within which the motion blur will be apparent.Because the base of the prop is moving slower than the tip, it will appear darker at the base.This darker region will extend out about half the length of the actual propeller blade, fading asit extends away from the propeller hub. In the image below on the right, you can see that theblur appears evenly on both sides of the propeller for both the dark region and the fainterwedge shaped area.

To create a blurred effect with a pencil, start by shading an area in (below left) and thensimply use your index finger to rub the paper (below right). This will spread the graphite moreevenly and give it a blurry appearance.

Page 109: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

When drawing a spinning prop from the side, make sure to account for the pitch of thepropeller blades. In the image below on the left, you can see how the blade above the spinnerappears narrow as compared to the blade below the spinner. This is because from our point ofview, the top blade is seen almost edge on whereas we see the flat side of the bottom blade.The image below on the right shows how this prop appears in motion.

As you study photos of airplanes in flight, you will notice that spinning props can take ona wide range of appearances. Sometimes they are very dark and prominent and other timesthey are barely visible. Sometimes they are quite broad and blurry and other times they

appear to be almost frozen in place. This is because many things affect the way spinningpropellers appear in pictures. The good news for you as an artist is that you have a lot ofoptions when drawing them. Choose the look that works best for your drawing.

Lesson 9: Drawing the P-51D Mustang

A Classic WWII Fighter

The Mustang is one of the most famous aircraft developed during the Second WorldWar. Many of these still fly at airshows today, and others have been modified for air racing. Itis a timeless aircraft that has beautiful curves and lines.

Let’s get started. Take a look at the 3-view drawing below. This is the P-51D Mustang.

A Closer Look at the Mustang

The P-51D Mustang was one of the most advanced fighters developed by the Alliesduring WWII. From its laminar flow wing to its bubble canopy to the mighty Packard-Merlinengine - a 12 cylinder, supercharged monster that could generate 1,720 hp at 25,000 ft - the

Page 112: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Mustang was the state of the art fighter of its day. The design of this plane gave it tremendousrange enabling it to escort heavy bombers deep into Germany and back home again. WhenThe Merlin powered Mustangs (B models) arrived in Europe in September of 1943, it was thebeginning of the end for the German Luftwaffe.

The P-51D is the most recognizable version of the Mustang, and it is the model we willbe drawing. The D model was the first to incorporate a bubble canopy which gave the pilot anunprecedented field of view. This innovation was so successful that almost every fighter todayhas one.

Adding a bubble canopy required the top of the tail section to be lowered. This causedthe fighter to become less stable in the yaw axis, so a dorsal fillet was added in front of thevertical tail to correct this problem.

Looking at the bottom of the fuselage in the side view above, you will notice two air-scoops or inlets. A small one under the nose is the carburetor inlet. This air goes back to thesupercharger which compresses the air. At high altitudes, thin air doesn’t provide enoughoxygen for fuel to combust. Superchargers compress the air at high altitudes so that theengine can perform as though it is at sea level.

The second air scoop, for the radiator, is under the wing as illustrated below. Thedesign of the radiator air scoop was another innovation of the Mustang. The designersreasoned that they could minimize drag by placing the radiator air scoop behind the wing sothat the air could flow out through air vents more easily. In fact, not only did the design reducedrag, but it actually improved performance because as the air heated up over the radiator, itexpanded and left the vents at a higher velocity than the cool air entering. In other words, itadded a little bit of forward thrust!

Page 113: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

The front view of the Mustang below shows these two air scoops clearly. It also showsthe three 50 caliber gun ports on each wing. Earlier versions of the Mustang had only two perwing. In addition to the extra guns, the D model had more rounds of ammo per gun thanearlier models.

I mentioned the laminar flow wing above and you may have been wondering what Imeant by that. Well, it is a type of symmetrical airfoil. You can see the outline of this airfoilbelow.

Laminar flow simply means that the air flows smoothly past a surface. With aconventional airfoil, air flows smoothly around the leading edge of the wing. As it travels

Page 114: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

further back along the wing, it begins to separate from the upper surface and becomesturbulent as seen in the image below. Back in the 1930’s, research at the National AdvisoryCommittee for Aeronautics (NACA) found that moving the chord (the thickest part of the wing)of a symmetrical airfoil closer to its midpoint, reduced the turbulent airflow over the wing. Thisbecame known as a laminar flow airfoil. Because the turbulence creates drag, this wingdesign had lower drag which increased the speed and range of the Mustang.

The top view below reveals another visually distinctive feature of the P-51D: the forwardcant of the inboard leading edge of the wings. This was done to make space for the wheelwells which were slightly larger in the D model.

Page 115: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Now take a look at the various cross-sections of the Mustang below. As you can see,the shape of the fuselage is generally rounded on top. The bottom is flat from the wings back,but in front of the wings it is rounded.

Page 116: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

One last point to make: the dots that are drawn along some of the panel lines are notrivets, but screw heads. Panels that need to be removed for maintenance, for example aroundthe engine, are held in place with screws. Most other panels are held in place by flush rivets.These rivets are small and difficult to see unless you get very close.

There’s much more to this famous fighter than what I have described here, but I think Ihave covered enough for us to do our drawing. As you can see, the Mustang is a trulyremarkable aircraft.

Step 1: Draw a Scaffold Based on a 3 View Drawing

Below is my version of the top scaffold.

Page 117: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Below is the scaffold without the top view of the Mustang. Notice I have added dottedlines to indicate the width of the fuselage.

Below is the side view scaffold. You can see the dihedral of the wings. The dihedral ismore obvious in the front view, but you should notice that in the side view, the wingtip is higherthan the base of the wing where it intersects the fuselage.

Page 118: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Below is the side view scaffold without the Mustang. Notice the reference lines I haveadded for the top of the canopy and fuselage and the bottom of the fuselage and radiatorintake.

Step 2: Draw the FRG

I’m going to draw the P-51 from slightly above, coming towards the viewer. As you cansee below, my intercept point is just above the oval center which gives me the amount ofconvergence that I desire for this drawing.

Page 119: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

In the figure below, I’ve added my remaining grid lines. Because this is a high aspectratio, we don’t need to foreshorten the Z axis at all.

Step 3: Transfer the Scaffold to the FRG

Below I have drawn my top and side view scaffolds on my FRG. You can now see theorientation of the plane.

Page 120: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Step 4: Use Projection to Adjust the Scaffold

The arrows in the figure below show how I have projected the wings and horizontalstabilizer.

Below is the finished scaffold on the FRG.

Page 121: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Step 5: Outline and Shape the Fuselage

Next, I draw the outline of the fuselage using the side view scaffold and reference grid.As you can see in the image below, it looks distorted because it is foreshortened so much.Don’t worry about how it looks at this point in the drawing. The important thing is to carefullystudy the side view scaffold and make sure you draw the outline accurately on the FRG. It willlook much more like a P-51 as we begin to shape it.

Below I have added the outline of the top view of the fuselage. The dotted lines helpme to judge the correct width of the fuselage.

Page 122: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Below I have drawn crosses where I will add bulkheads.

For reference, below are the bulkheads along the length of the fuselage.

Page 123: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Below I have drawn boxes to help me visualize the shape of the bulkheads. Rememberyou can also add gridlines inside the boxes if you are unsure of how to draw them.

Below I have drawn all my bulkheads.

Page 124: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Next, I draw the silhouette of the fuselage using the inflection points of the bulkheads.This is shown in the image below. Some good photographic references are helpful when youdo this. There are almost always bulges and curves that are hard to see with a simple 3-viewdrawing. For example, the upper surface of the Mustang’s nose grows flatter near thepropeller spinner. Pay attention to these extra bulges and curves because they will make allthe difference in getting an accurate “likeness” of the aircraft.

Next, I will focus on the canopy. The canopy is a tricky thing to draw. It has a verydistinctive silhouette that you need to get right. Below I have drawn a simple guide that dividesthe front and rear portions of the canopy.

Page 125: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Next, I added a guide for the central panel of the windscreen in the drawing below.Study photographs and the 3-view drawing and you’ll see that it is shaped like a trapezoid.

The drawing below shows the last part of my guide which is an outline of the base of therear canopy and the frame where the front and rear parts of the canopy join together.

Below is the finished canopy. Once again use your photographs to get this looking justright. Three-view drawings will not have enough detail in most cases.

Page 126: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Step 6: Outline and Shape the Wings and Tail

Straight lines make outlining the wings and tail easy. The wingtips are a little curved asyou can see below.

Remember, the inboard leading edge of the wings is angled forward. Below I’ve addeda guide to help me visualize that portion of the wing.

Below I have drawn the wing ribs. I draw enough ribs to help me visualize the shape ofthe wing. The Mustang is covered in metal so these ribs won’t be visible in the finisheddrawing as they were for the Piper Cub.

Page 127: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Drawing the ribs shows me that the lower edge of the wing extends below the outline Ihave drawn. Notice I have added a guide to help me visualize where the wing intersects withthe fuselage in the image below.

Below are the outlined and shaped wings.

The horizontal stabilizer has a symmetrical airfoil, just like the wings, but it is so thin thatI am not going to bother drawing any ribs. I did draw the elevator hinge line as you can seebelow.

Page 128: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Step 7: Clean up and Final Details

With all the major parts of the Mustang drawn, I am ready to draw the final details andclean up my guides. The first things I will draw are panel lines. Starting with the wings andhorizontal tail, I use the bulkheads and ribs as guides help me draw them. I use my 3-viewdrawing and photos as references. The image below shows these panel lines.

Below I have added panel lines for the fuselage and vertical tail. You can see how theunderlying guides and bulkheads help me to estimate the correct location of the panel lines.Drawing panel lines will test your artist vision, so be patient. Because panel lines are notalways aligned with the underlying bulkheads, you will have to use some trial and error to getthem right.

Page 129: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Below I have cleaned everything up and added some more details. What a beautifulplane!

Sketching the Mustang

Below is the finished sketch of the Mustang based on my black and white drawing. I

chose markings of Captain Robert Schmidt’s “Tar Baby” of the 356th Fighter Group. The Noseand Rudder are painted bright red. A navy blue diamond pattern covers the nose. The rest ofthe aircraft is bare aluminum.

Page 130: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Early in the war, aircraft were completely painted with camouflage paint. This reducedspecular reflections and sometimes made them harder to see. Unfortunately, that much paintalso added weight, increased drag, and added cost. Later in the war, it was seen as better toskip the paint and leave most of the aluminum bare. They did add colorful markings to helppilots find their squadron mates. Unfortunately in a black and white sketch you can’t see allthose wonderful colors.

Probably the biggest challenge in sketching the Mustang is conveying the impression ofbare aluminum. And that leads us to the next topic.

Drawing Bare Aluminum

Bare aluminum can be a bit of a challenge, and even very talented artists can strugglewith how to do it right. The key to drawing aluminum is understanding how light and shadowplay off of this surface. In fact, all we will do is apply the same principles of direct and indirectlight that I explained to you in the previous lesson.

One of the things that makes aluminum difficult to draw is that in some ways it acts likea matte surface and in other ways it acts like a glossy surface. You can think of aluminum as ascuffed up mirror. This means that it tends to reflect light from the environment, but thereflections are very diffuse or hazy.

Because of this, unlike a matte surface, you will not see very distinct shadows on analuminum skinned aircraft. Aluminum reflects a lot of light from the environment, so theshadows will tend to be illuminated by indirect light. If you look at photographs of aluminumaircraft, be aware that photos tend to accentuate shadows. This is because camera film andeven modern digital sensors are less sensitive in dim light than is the human eye. To really getaluminum right, you should minimize the appearance of shadows.

The sphere below has an aluminum finish. This shows a key feature of aluminum: avery bright and diffuse specular light reflection. You can also see a dark reflection along thehorizon line, but it too is very diffuse. In aluminum, reflections should always be diffuse orhazy. Finally, notice that there is not much of a shadow visible. In fact you can see the diffusereflection of the bright surface in the lower half of the sphere. What you might mistake for ashadow at the very bottom of the sphere is actually the reflection of the shadow cast on thesurface.

Page 131: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Now let’s take a look at the polished chrome surface in the image below. To draw achrome finish, use the same approach as for a glossy finish. All reflections are sharp and welldefined and have more contrast than aluminum. Because chrome is so mirror like, you willnever see a shadow except for ones reflected in the polished surface. For example, you cansee the reflection of the shadow cast on the surface at the bottom of the sphere.

Below is an example of chrome and aluminum reflections on a cylinder. This is similarto what you might see on the fuselage of an aircraft. Reflections in a cylinder tend to appearas dark and light bands running the length of the cylinder. By making the bands well definedwith high contrast,

Page 132: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

you will create the appearance of chrome. If they are diffuse with less contrast it willhave the appearance of aluminum.

A very good way to learn how to draw reflective surfaces is to study the way lightreflects off of automobiles. Notice how different surfaces reflect light and color from theenvironment. Pay attention to the way the curvature of different surfaces distort thereflections. The more you understand how surfaces reflect light, the easier it will be to createthose effects in your drawings.

Getting back to our sketch of the P-51, in the image below you can see the uppersurfaces of the wings and horizontal stabilizers are dark because they are reflecting the darkblue sky above. On the left wing, you will also notice some reflections of darker markings onthe fuselage. There are large diffuse specular reflections on the upper surface of the fuselageand along the wing fillet. You can also see the reflection of white clouds around the bottom ofthe nose.

Below I have given the Mustang a “polished” finish. Notice that the reflections on thefuselage and upper surface of the wings are much more distinct and have more contrast thanthe aluminum version.

Checkertail Mustang

In contrast with the subdued gray markings of today’s military aircraft, aircraft of WWIIwere quite colorful. As I mentioned above, the colors and patterns helped the pilots find theirsquadron mates in the air. Below is a mustang with markings that would definitely be easy tospot.

I’ve decided to draw this Mustang just about to takeoff. Below you can see how I drewmy reference grid and scaffold.

Below is the outline of the P-51 drawn on the scaffold. Notice the landing gear areextended.

Below is the final sketch. He’s just about at takeoff speed! This particular P-51

belonged to Captain Harry Parker in the325th Fighter Group. This group was known as the“Checkertails” for obvious reasons. The checkers are black on a yellow background. Thepropeller spinner and the tip of the nose are painted in red and there are yellow stripes on thewings. The rest of the Mustang was bare aluminum.

Lesson 10: Drawing the F-4 Phantom II

Introduction

The Phantom has to be one of the coolest fighter jets ever built. When it enteredservice in 1961, it set altitude and speed records and was so impressive that all three servicesadopted it as their primary fighter. It could land on the deck of an aircraft carrier and couldcarry more bombs than a B-17. Soon after it entered operational service, it became America’spremier fighter in Vietnam and it more than held its own against more nimble adversaries fromthe Soviet Union like the Mig-17, and -21.

It is hard to believe today, but when the Phantom first came out, it was not regarded asa thing of beauty. Lacking the clean, simple lines of earlier jets like the F-86, it was nicknamed“double-ugly.” To me, it is anything but ugly. From the sloped down stabilizers in the tail to thebig rectangular air intakes to the two jet exhaust nozzles tucked up under the tail, the Phantomis simply awesome looking. The variant that we are going to draw is the E model, introducedin 1967. This model incorporated an internal 20mm Gatling gun. The ammo was stored in alarge drum in the nose. Because of this addition, the E had an extra long nose section whencompared to earlier B and C models. This plane flew combat across four decades fromVietnam to the Gulf war.

Below is a 3-view drawing of the F-4E Phantom. Though it has many straight lines, aclose look at the fuselage will reveal a very curvaceous figure. In the top view, you’ll notice ithas a bit of an hourglass shape. This was referred to as a coke-bottle fuselage, a commonfeature of this generation of fighter. This aerodynamic feature reduced drag as the aircraftapproached the speed of sound.

A Closer Look at the F-4E Phantom

We are going to draw the Phantom from the side and slightly behind and below, so weneed to study the side, rear, and bottom views of this plane. Starting with the side view, I wantto point out some unique features. Under the nose you can see the 20mm gun. Because thiswas a Mach 2 fighter, the gun had to be enclosed in a fairing under the nose. Early versions ofthe Phantom had no gun because it was believed that guided missiles had ended the era ofdogfighting. Tactical experience over Vietnam proved this theory to be incorrect, and so the Emodel included a very serious gun.

The Phantom had a 2 person crew that sat in tandem. The pilot sat in front and aweapons officer sat in the rear. You can see both positions in the side view below.

Just in front of each engine intake is very distinctive engine intake vane. Its purposewas to slow a supersonic airstream down to a subsonic speed before it entered the engine.

Page 137: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

The vane worked automatically to narrow the opening in the air scoop as the jet flew faster. Ifthe air wasn’t slowed down, it would literally pile up in front of the compressor blades and theengine would flame out.

Missiles, fuel tanks, and other ordinance were mounted under the wings on pylons or athard points under the fuselage. The pylons could be configured for different weapons. Therewere two pylon mounts under each wing. In addition, there were recessed mounting points forfour AIM-7 Sparrow radar-guided missiles under the fuselage.

The Phantom, like all supersonic fighters, does not have elevators on its horizontalstabilizers. Instead, the entire horizontal stabilizer rotates to control aircraft pitch. This type oftail is called a stabilator (stabilizer + elevator = stabilator) or an all-flying tail. The stabilatorsare “transparent” in this side view so that you can see the shape of the fuselage all the way tothe tip of the tail. Notice that it is not a straight line.

The Phantom had two J-79 General Electric turbojet engines that generated a combined23,810 lbs of thrust dry and 35,800 lbs of thrust in full afterburner. The two engine exhaustnozzles were tucked up under the tail. You will notice in photographs that the nozzles could bepartly closed down or opened up. The nozzles were constricted at cruising speeds to maintaincompression in the engines and increase the thrust. When constricted, they have a conicalshape as shown below. Think about what happens when you put your thumb over the end of awater hose. Pressure increases behind your thumb and the water shoots out of the end of thehose much faster. At full power (afterburners on), the nozzles are opened up all the way,otherwise there would be too much pressure built up inside of the engines.

You can see that there is not much space between the engine nozzles in the rear viewbelow. They are divided by a thin wall. Above the nozzles, the tail is thicker. This part of the

Page 138: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

tail can be very difficult to visualize from 3-view drawings alone, so finding some goodphotographs or a good quality plastic model will help you.

There is also a tail hook situated between the nozzles. The F-4 was originally designedfor the Navy, and as you probably know, landing on an aircraft carrier requires a tail hook. Youwill also notice that Phantoms built for the Air Force had a tail hook. As it turns out, Air forcepilots sometimes needed to use the tail hook in emergencies to stop after landing. ThePhantom also had a drag chute that could deploy from the end of the tail for a little extra helpslowing down.

From the rear, you can see the wing tip dihedral and the anhedral (downward slope) ofthe stabilators in the tail. On the Navy versions of the F-4, the wing tips could be folded up toconserve space aboard an aircraft carrier.

Taking a look at the bottom of the F-4E below, you can clearly see all the mountingpoints for missiles, etc. You can also see the outline of the landing gear doors and the speedbrakes.

Page 139: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

One of the big challenges of flying swept wing aircraft is that they have fairly high stallspeeds. To help improve performance at lower speeds, the Phantom has both leading- andtrailing edge flaps. You can see three actuators for these flaps on the inboard portion of eachwing in the bottom view. On earlier models of the Phantom, the outer wing sections also hadleading edge flaps, but on the E model, the flaps were replaced with leading edge slats. Theleading edge slats also help to prevent high speed stalls during high angle of attackmaneuvers (i.e., sharp turns). The jag (also called a dogtooth) in the leading edge of theoutboard section of the wings was another feature that reduced stalls during high angle ofattack maneuvers.

Finally, take a look at the bulkheads along the fuselage of the Phantom below. You cansee that no two of them look anything alike. This plane has more bulges and bumps than atoad! The top of the fuselage is generally rounded. Under the wings, the fuselage is relativelyflat and then the shape changes again in the tail. The fairings over the engines are flat on topnear the intakes but become increasingly sloped towards the exhaust nozzles. Photographsand/or a good scale model are very helpful in understanding the complex shape of thisfuselage.

Page 140: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

There are many more design features of the Phantom than I can possibly discuss here.I have covered the ones that are most important for our drawing, so let’s get started.

Step 1: Draw a Scaffold Based on a 3 View Drawing

Below is our top view scaffold for the Phantom. It is a line and two triangles - prettysimple.

And below is the side view scaffold. Notice that the tail extends up a distance equal tothe height of the fuselage.

Page 141: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Below is a less obscured view of the side view drawing and scaffold. You should noticethat the canopy bulges slightly above the top scaffold line. You should also notice that thefuselage around the exhaust nozzle extends below the bottom line of the scaffold. This isbecause the Phantom’s engines were actually canted so the nozzles were pointed slightlydown.

Below is the final scaffold drawn inside the side view reference grid.

Page 142: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Step 2: Draw the FRG

Below is a simple technique for drawing an oval. Start with a cross made of the majorand minor axes and then add caps to the ends of each axis.

Next, connect the caps to draw the oval as you can see in the drawing below. I had totweak the lines a bit till I got it looking right. Drawing the major and minor axes helps to keepeverything symmetrical. It’s not a perfect oval, but it will work for our drawing. With an aspectratio of 4:1, we don’t need to foreshorten our Z axis.

Our Phantom is heading to the right and slightly away from the viewer. I’ve drawn the Xand Y axes accordingly and have added the sides of the top view reference grid by drawinglines tangent to the points where those axes intersect the oval. Notice below that the X and Yaxes intersect below the center of the oval. This is because we are looking up from below.

I add the remaining gridlines for the top view reference grid below.

Page 143: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Below I have added the gridlines for the side view reference grid. We only need to addthe grid squares above the top view to complete the FRG.

Step 3: Transfer the Scaffold to the FRG

First, I draw the two triangles for the wing and tail scaffolds as you can see in the imagebelow.

Page 144: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Then I draw the side view scaffold seen below.

Step 4: Use Projection to Adjust the Scaffold

I have drawn some arrows to serve as guides for how much I will project the wings andtail as you can see below. Remember, only the wing tips have dihedral.

In the image below, the wings and stabilators are drawn in their projected positions.

Page 145: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Below I have cleaned things up a bit. This scaffold definitely resembles the Phantom.

Step 5: Outline and Shape the Fuselage

Below I have outlined the fuselage. The outline is primarily done with straight lines so itisn’t too difficult. The nose section is the most challenging, but if you pay attention to thescaffold and side view, you’ll be able to do it. Just be patient.

Page 146: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

To draw the outline of the fuselage top view, I start with some guidelines as shownbelow.

This helps me to draw the outline in the image below.

Page 147: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Below I have added some vertical and horizontal references to help me draw myfuselage bulkheads.

The side view drawing showing the location of each of the bulkheads is displayed belowfor review.

I have drawn the bulkheads using my reference lines as guides in the image below.One main reason the fuselage shape is so complex is because it is formed around the twoGeneral Electric J-79 engines. Near the nose are large rectangular intakes and under the tailare the two round engine exhaust nozzles.

Page 148: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Below I have drawn the silhouette of the intake and the bulge of the fuselage over thoseengines. The dashed lines near the tail indicate that the bulge in the fuselage is formed by asmooth curve rather than a distinct edge.

Below I have drawn the silhouette of the fuselage and I have outlined the tail hook.Because we are close to a side view, the silhouette is not very different from the side viewdrawing.

Page 149: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

The silhouette at the top of the fuselage is slightly raised above the side view outline.Below is a close up. Truthfully, it is such a small change that you could ignore it if you wantedto.

Step 6: Outline and Shape the Wings and Tail

Below I have outlined the wings and tail. The tail is virtually the same as the scaffold,but the wings require some adjustment as you can see below. Because they are drawncompletely with straight lines this isn’t too difficult to do. Notice the dogtooth jag on theoutboard part of the wing. This is a very salient characteristic of the Phantom’s wing, so wewant to make sure we draw it.

High performance jets have very thin wings and control surfaces. From our vantagepoint the wing surface appears almost flat. Therefore in this drawing, I don’t need to worryabout drawing the wing airfoils.

Page 150: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Step 7: Clean up and Final Details

The first details I add are the engine nozzles. Recall that they point down just a littlebit. Most likely this was to counteract a tendency of the nose to pitch up, possibly because thenozzles are below the centerline of the fuselage. Whatever the reason, I start with simplecylinders to help me visualize the size and position of the nozzles as you can see below.

Next, I add more detail to the nozzles and rear part of the fuselage in the image below.As described above, the F-4 has variable geometry nozzles that can partially close like thepupil of your eye (it is actually called an iris nozzle). I have drawn the nozzles in an openposition, as if the engine was at full thrust.

Page 151: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Next, I add details like panel lines around the nose section in the image below.

Below I have created a guide to help me draw the cockpit.

Page 152: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Below I have added some details like the pilot, weapons officer, and the tops of theejection seats.

Below I have drawn details on the wings and stabilators. Notice the leading edge flapactuators on the inboard portion of each wing.

Page 153: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

I’m going to draw this Phantom with a full load of air-to-air weapons as well as under-wing fuel tanks. I start by drawing four AIM-7 Sparrow missiles in the recessed hardpoints.The AIM-7 was a medium-range, radar-guided missile. These recessed mounts helped toreduce wind resistance as well as the radar signature of the Phantom. This is shown in theimage below.

Below I have added the four under-wing pylons. I will draw two AIM-9 “Sidewinder”missiles on each inboard pylon and an under-wing fuel tank on each outboard pylon.

Page 154: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Below are the finished AIM-9 Sidewinders. The Sidewinder was an infrared-guided,short-range missile.

Finally, I add the fuel tanks. The fuel tanks were long and thin and the pylons attachednear the rear of the tanks. The tanks extend forward to about where the leading edge of thewings intersects the fuselage. To help me visualize the location of the under-wing fuel tanks, Idrew some guidelines as you can see below. Notice that they slope down just a little.

Page 155: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Below is the final line drawing.

Sketching the Phantom II

The F-4 Phantom had a variety of paint schemes during the Vietnam War. In the AirForce a green, olive, and tan camouflage pattern was common. The Navy used a light graybase with many colorful markings, especially on the huge vertical stabilizer. Sadly for usartists, this was the last era of such bold, colorful markings. Both services now use a light graypaint scheme and subdued markings on almost all their aircraft.

The sketch below is of an Air Force Phantom flown during the Vietnam War. This

Phantom was flown by COL Grady Morris of the 469th Tactical Fighter Squadron, 388th Tactical

Fighter Wing. In mid 1968, the 388th received new F-4Es which they flew until the end of theconflict. They were stationed at Korat Royal Thai Air Force Base. This Phantom had thetypical Army camouflage pattern. The underside was painted light gray and the squadronmarkings were in white.

Page 156: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

I have placed the light source almost directly above the aircraft. This allows the shapeof the Phantom fuselage to pop out. I’ve deliberately made the upper reflections very bright toconvey a sense of strong sunlight above. Remember that matte paint will not reflect muchindirect light, so the shadows need to be strong. When you do a painting or drawing,increasing the contrast between light and shadow is a technique that helps to create a senseof bright light.

Composition

So far in this book, we have been focused on drawing airplanes. Drawing airplanes,however, is not an end in itself. Because you are an artist, you want to tell a story about thataircraft. You want to convey an idea about the wonder and beauty of flight or about theheroism, courage, or self-sacrifice of the air crew.

Artists use composition to convey these stories, ideas, and feelings in their images.Composition is simply the way the elements of the image are arranged within the frame. Asuccessful composition will lead the viewer to see and experience those feelings, ideas, and/orstories. Okay, enough talk, let’s look at some examples.

Quite often, aviation artists choose to have a single aircraft dominate theircompositions. Below you can see an example of what I mean. A single F-4E is front andcenter, and it looks like its prey is going down in flames! This picture certainly has interest andbalance. To someone who loves the Phantom, this kind of picture might be just what he or sheis looking for.

Page 157: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

There is nothing wrong with this composition, but if every drawing or painting you dorelies on this approach (a single plane dominating the frame), your portfolio of work will be verymonotonous. Let’s see what happens when we expand the frame of our picture.

Below is a very similar composition to the one above, but as you can see, we havemuch more space around the F4-E to tell our story. For example, you can see the whole trailof smoke from the burning MiG all the way back to where it was hit. You should also noticethat by expanding our frame, the sky has become bigger. In other words, this picture conveysa greater sense of depth and space around our subject.

When developing your composition, you want to think about how the viewer’s eye willmove through the image. To do this, we have to identify what are called points of interestwithin our frame. The main points of interest in this image are the F-4E, the MiG, and thesmoke trail. The first thing the viewer will probably pay attention to is the F-4E. This isbecause it is in the foreground and it is centered within the frame. Next, we would expect theviewer to notice the burning MiG (the next most interesting object), and finally the smoke trail.

Page 158: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

This composition results in a nice fluid movement of the viewer’s eye through the image. Isthat how you viewed this composition?

Finally, the background provides some relevant references, but we don’t ever want ourbackground to overtake the points of interest in our painting. The background shows us thehorizon line through the center of the painting. There are some nice puffy clouds to add depthwith the sky above and the ground below.

Having our main subject (the F-4E) centered on the canvas, helps to keep the paintingbalanced, but artists have found that placing the main subject off-center makes it possible tocreate a more interesting composition. Artist sometimes use what is called the rule of thirdswhen developing a composition. The idea is that if you divide your frame into three equalparts, left to right and top to bottom, you will have four points around the center at which youcan place major points of interest. The image below illustrates this rule.

I’m only going to talk about the rule of thirds here, but as you learn more aboutcomposition, you will see that there are many more rules. One thing to keep in mind about allthese “rules” is that it is better to think of them as guidelines. As you look at paintings anddrawings of other artists, you will probably find examples of perfectly successful compositionsthat violate many of these so-called rules.

Suppose we position our F-4E near one of these four points using the rule of thirds. Asyou can see in the image below, this creates a sense of imbalance in our image. There isempty space above and to the right of the Phantom. Your eye probably naturally looks up tothat empty area expecting to see something important. To re-balance the image, we need toplace a point of interest in that space.

Page 159: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Below you can see that I have added a formation of Phantoms doing some aerialrefueling. Notice how this rebalances the image. This composition also illustrates an importantprinciple which is that groups of objects can become a single point of interest. In this case, thetanker and three trailing Phantoms all form a single point of interest. Anytime severalindividual things are grouped together such that no one of them is more interesting orimportant than the others, they will be perceived as a single point of interest. Other examplesare groups of clouds, trees (forest), and houses and buildings (cities).

In the composition above the viewer’s eye will typically start by focusing on the F-4 inthe foreground and then move to the refueling aircraft. This creates a nice flow through thecomposition while maintaining a sense of balance when viewed as a whole. Also, notice that Ihave drawn the horizon line low in my frame. This creates the impression that you are lookingup towards the sky. I have also used high cirrus clouds to create a light background for myrefueling aircraft. This helps them to stand out in my composition.

Page 160: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Let’s look at one final example. In the image below I have placed the foreground F-4Eon the top right point defined by our rule of thirds. I have balanced it by drawing a secondF-4E flying in formation below and to the left. In this drawing the horizon is somewhere abovethe top of our frame. This creates the impression that you are looking down towards theground at these aircraft.

Hopefully you can see that using this rule of thirds helps to create interestingcompositions. Of course there are many other ways to compose a painting and many other“rules” of composition that can help you. This brief section is only meant to give you an ideaof the importance of composition.

As any good artist does, you should spend time studying the work of others. Whetherthey are paintings of airplanes, landscapes, still life, or any other subject, you should try tounderstand how the artist has chosen to compose his or her paintings. Think about how thecomposition leads your eye over the various points of interest. Think about why the artistchose that composition and whether you think he or she was successful in creating that workof art. In this way you can learn from other artists and create more exciting compositions ofyour own.

Using Thumbnail Sketches

Thumbnail sketches are quick, small sketches that can be used to explore alternatecompositions. In this section, I will discuss how I used thumbnail sketches to create acomposition showing a Navy F-4 Phantom landing on a carrier.

The Phantom in the drawing will be from Fighter squadron VF-84, the Jolly Rogers.From 1964 to 1976, this squadron flew the F-4 Phantom. During the Vietnam conflict, theydeployed aboard the U.S.S. Independence. Drawing this jet on final approach for landingmeans that the two most important points of interest in my composition will be the aircraft andthe carrier.

Page 161: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

As in any project, I had to make some decisions about my final composition. First andforemost, I had to think about various points of view that would allow me to include both thePhantom and the carrier. For example, I could do the drawing from the carrier deck looking atthe approaching Phantom. This would show only a limited view of the carrier deck, but it wouldshow the jet coming towards the viewer. On the other hand, it would place the Phantom in thebackground which I felt would diminish the sense of the excitement of a carrier landing.

I could show the landing from a distance off to the side of the carrier. The carrier wouldfit in the frame, but the Phantom would be tiny. This composition would really be a painting ofthe carrier more than of the Phantom. A third possibility would be to place my point of viewclose to the Phantom and behind with the Independence in the distance. In this compositionthe viewer would see the small size of the landing strip which would convey that feeling ofsuspense that all carrier landings must evoke. This was the point of view that I chose.

Just choosing that point of view is only one step in determining the final composition.There are still lots of decisions to make. For example, how far behind the landing Phantomshould the viewer to be positioned? Placing the viewpoint directly behind the aircraft wouldlimit the view of the squadron markings (which are mostly visible from the side). Too far to oneside and it would be difficult to place the carrier in the scene. Also, I had to think about how farfrom the carrier I wanted to place the Phantom. Showing it just as it was landing might createa sense of action, but I would risk having the carrier be so large that it would overwhelm myforeground aircraft. Showing the carrier too far in the distance might diminish the sense ofaction.

As you have probably guessed, this is where thumbnail sketches come in very handy.Below are three examples I used to explore different ideas. The first thumbnail below couldwork. Although this composition has balance, I feel like the Phantom is chasing the carrierrather than landing on it.

In the next thumbnail sketch below, I have positioned my point of view further behind thePhantom. I like this point of view much better since there is no doubt that the Phantom islanding. On the other hand, I worry that the size of the Independence makes it compete as apoint of interest with the Phantom.

Page 162: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

In this final thumbnail I placed the viewpoint closer to the Phantom and I moved thecarrier father away. To me, this was the best solution since it placed the emphasis on thePhantom while maintaining the excitement of a carrier landing. This is how I decided tocompose my final drawing. As you can see below, even with just two points of interest, thereare many ways to vary the composition.

After working out my point of view and the locations of my key points of interest, I wasready to start the final drawing. Below is my scaffold and FRG. Notice that I drew my oval andthen extended my reference grid outward. This was necessary because had I done a full sizedoval, the ends of it would have been off the edges of my frame.

Page 163: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

As you know, the shape of the Phantom’s fuselage is very complex. This is wheresketching the individual bulkheads really helps me visualize its shape. The image below showsthese bulkhead lines along the fuselage.

Below is the drawing of the Phantom with all of the major parts outlined and shaped.

Page 164: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Below is the final drawing. I had assumed that with the plane to the left of center andthe carrier to the right, my composition would be balanced. I was wrong. I found that most ofthe focus was between the Phantom and the Independence, which left the compositionunbalanced to the right. I needed something to rebalance things, so I placed a small ship inthe distance to the left of the Phantom. That simple change worked. Don’t everunderestimate the importance of every point of interest. Put your finger over the ship in the topleft of the image below and you will see how the composition seems unbalanced.

You can see that I have placed the light source low so that the upper surfaces of thewings and fuselage are shaded. Drawing the markings was a little tricky because they were soforeshortened. Having a good understanding of the complex shape of the fuselage was criticalfor getting the shading and markings just right. I’d say our pilot will definitely catch the firstwire!

Lesson 11: Drawing the Sukhoi Su-27

Fourth Generation Fighters

After the Vietnam conflict the United States began producing a new generation offighters exemplified by the F-15 Eagle and the F16 Falcon. These were highly maneuverableaircraft that were equipped with advanced sensors and avionics and smart weapons. Theybecame known as fourth generation fighters, and they gave the United States and its allies adistinct advantage against aircraft used by the former Soviet Union.

To counter these new fighters, the Soviets began development of two of their own fourthgeneration fighters: the Mikoyan MIG-29 and the larger Sukhoi SU-27. Both aircraft enteredproduction in the 1980’s, and it quickly became clear that they were formidable opponents. In1986 the SU-27 broke several flight records previously held by the F-15.

At airshows the SU-27 wows the crowds with a maneuver known as Pugachev’sCobra. In this maneuver the pilot, flying low and slow, pulls the nose just beyond the verticalwithout gaining altitude. For any other jet fighter, this maneuver would result in a stall andcrash. But, the SU-27 practically hovers with its nose pointing up before the pilot drops it backdown and accelerates away. It is an impressive display of the aircraft’s power andmaneuverability. Below is a 3-view drawing of this remarkable jet.

A Closer Look at the SU-27 Flanker B

The SU-27 Flanker (Flanker is the NATO designation) has been a huge success forSukhoi. Many variants of this airframe have been built including versions for the Russian AirForce and Navy and two different two-seat configurations, one tandem and one side-by-side.It has been exported to over a dozen countries. The original production version, that we willdraw, is the SU-27S or Flanker B. It was produced from the mid 1980’s to the early 1990’s. Itunderwent its first modernization in the early 2000’s (SU-27SM), getting better avionics, an allglass cockpit, improved radar, engines, and a host of other changes.

The most advanced iteration of this design (SU-27M2, also known as the SU-35S), iscompletely modernized with thrust-vectoring engines, updated sensors and avionics, and astronger, stealthier airframe. Its NATO designation is the Flanker-E, but some call it the Super-Flanker. It is considered a 4.5 generation fighter because it bridges the gap between fourthand fifth generation stealth fighters like the U.S. Air Force’s F-22 Raptor. Super Flankerproduction began in 2010.

Like other fourth generation fighters, the SU-27S incorporates a design feature knownas relaxed static stability. This means that the plane does not naturally fly straight and level.If you look at the front view of the SU-27 below, you can see one reason for this: there is nowing dihedral.

Relaxed static stability makes aircraft much more maneuverable but also harder tocontrol. This is because constant input is required just to fly straight and level. Fortunately,fourth generation fighters have computerized flight control systems called fly-by-wiresystems. The pilot moves the control stick and the computer determines which controlsurfaces to move. If the pilot holds the stick still, the fly-by-wire system constantly moves thecontrol surfaces to keep the plane flying level.

The Flanker B can carry a wide array of air-to-air and air-to-ground munitions. Theseare mounted on 10 hardpoints: one on each wingtip, two under each wing, one under eachengine and two along the midline between the engines.

Page 168: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

You should notice in the front view that the fuselage and wings blend together. This iscalled a blended wing-fuselage design or a lifting body, and it increases overall lift. Youshould also notice that the Flanker has two vertical stabilizers just like the F-15. That extrarudder control is necessary to counter the asymmetric thrust that would result if one of theengines failed.

The Flanker B is powered by two Saturn-Lyulka AL-31F turbofan engines that generatea combined 33,400 pounds of thrust dry which increases to 55,000 pounds of thrust when theafterburners are engaged. With so much power, it can climb at an astonishing 59,000 feet perminute and it can reach a speed of Mach 2.35.

The intakes of jets produce tremendous suction. Because the SU-27’s intakes areunder the wings, they will suck up small rocks, sticks, and other debris on the ground when theaircraft is taxiing or taking off. Normally, such debris would be carefully removed from taxiwaysand runways, but during a conflict that might not be possible. To protect the engines, screensautomatically deploy over the intakes while the plane is on the ground and retract after takeoff.This unique feature fits with the Soviet design philosophy of building rugged, easy to maintainaircraft.

In both the front and side views, you can see an infrared search and track (IRST) poddirectly in front of the canopy. This pod is linked to the pilot’s helmet so that wherever the pilotlooks, the pod aims. It can be used to lock onto targets by their heat signatures at closeranges. This is a handy tracking device in an era of increasingly stealthy (i.e., low radarsignature) adversaries. In later versions of the Flanker (e.g., SU-27SM, SU-35), the IRST islocated to the right of the centerline to improve forward visibility for the pilot.

The side view below really shows off the unique and beautiful shape of the Flanker. Itsdrooping nose and engines that are set back under the wings give it the appearance of havinga long, graceful neck.

Like the F-15, the Flanker B has a dorsal airbrake that extends up from the top of thefuselage behind the canopy. It is deployed during landings to help slow the plane down but itcan also be deployed in flight. This dorsal airbrake was removed from the design of theSU-35. Instead it uses differential deflection of the rudders to slow down.

Near the rear of the aircraft, under the vertical tail, is something called a strake. Theventral strake is a non-moving airfoil that provides stability, especially at high angles of

Page 169: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

attack. During such maneuvers, airflow across the vertical stabilizers is disrupted whichreduces yaw stability. The ventral strakes help to keep the plane from yawing left or rightduring high angle of attack maneuvers.

Another very distinctive feature of the Flanker is its “stinger”. The stinger, or tail boom,houses a rear-facing radar that allows the pilot to track aircraft behind it. The stinger alsohouses a drag chute which can be deployed to help the plane slow down after landing.

In the top view of the Flanker below, you can see it has cropped delta wings andstabilators. The fuselage behind the canopy appears to widen as it approaches the wings.This region is called a leading edge root extension or LERX. This feature improvesperformance at high angles of attack. During a sharp turn, the LERX on each wing creates aspinning column of air, called a vortex, that keeps the airflow moving over the upper surfacesof the wings and prevents the plane from entering a stall. If you look at photographs ofFlankers (or any jet with a LERX) pulling high G turns, you will see the condensation cloudcaused by the vortex that forms behind each LERX. A 30mm gun is housed in the LERX onthe right side of the cockpit.

The wing of the Flanker has leading edge flaps just like the Phantom II. The leadingedge flaps are used during landings, but they also can deploy during sharp turns and otherhigh angle-of-attack maneuvers to prevent stalls. The wing also incorporates what are calledflaperons (flaps + ailerons). These surfaces function like flaps during landings, but they alsomove with the ailerons to help improve the roll rate of the aircraft at low airspeeds. With somany complex control surfaces on the wings, you could imagine the pilot would be quite busyadjusting them. Fortunately, the fly-by-wire system automatically makes all of those decisionsand adjustments for the pilot. In fact, you will sometimes hear pilots of fourth generationfighters comment that they are easier to fly than a prop trainer which needs constant trimming

Page 170: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

and attention. That’s not to say that a modern fighter pilot’s job is easy. Those fly-by-wiresystems are very necessary. When missiles and bullets are flying, you don’t want anydistractions!

Finally, when we examine the cross-sectional views of the Flanker, you can see that thefuselage does not run the whole length of the plane. The fuselage diminishes in size betweenthe wings. The cross-sections reveal the blended wing-fuselage design as you can see in theimage below.

In fact, what I have drawn as the fuselage cross-section between the wings is not aconventional fuselage. You might think that it is as much wing as fuselage. That’s okay. Youcan divide the wing and fuselage any way you like. If you consider the engines to be part ofthe wings, you will just have to draw the engine cross-sections when you shape the wings.

Well, there’s much more we could discuss about this remarkable aircraft, but we’vecovered enough to do our drawing. In this lesson, I’m going to show you how to do a drawingof the SU-27 coming straight at you. You may not have thought about this yet, but drawing thatview requires us to make a slight modification to the approach we’ve been using to drawairplanes. You’ll see what I mean in step 2 of our process.

Step 1: Draw a Scaffold Based on a 3-View Drawing

Below is the side view scaffold for the SU-27. Despite the drooping nose of this aircraft,a straight horizontal line passes through the tip of the nose and the tip of the tail boom.

Page 171: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

The top view scaffold is not complex as you can see in the image below. Because thewings and horizontal tail surfaces have straight edges, our scaffold will pretty much serve asan outline for them.

Step 2: Draw the FRG

Below is the top view FRG. I want to draw the Flanker from slightly above, comingstraight at the viewer. This means that the axis of my fuselage will be a vertical line. If I try todraw my side view reference grid on that same axis, all my lines will overlap, so what do wedo?

Page 172: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

We just have to improvise a little. Take a look at the drawing below. All I have done isto move my side view scaffold to the left of center. This way, I can see all my side viewgridlines. When developing my drawing, I will just project lines from my side view scaffoldacross the top view scaffold. If you’re confused, read on and you will see it is easy to do.

Step 3: Transfer the Scaffold to the FRG

Below I have drawn the top and side view scaffolds on the FRG.

Page 173: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Step 4: Use Projection to Adjust the Scaffold

Below I have projected the wings up a little and the horizontal tail down a little.

Step 5: Outline and Shape the Fuselage

I used the grid method to help me draw the outline of the top view of the fuselage.Below is the grid on the top view drawing and scaffold

Page 174: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Adding those same gridlines to my FRG enables me to more easily draw theforeshortened top view as you can see in the drawing below.

Drawing the side view wasn’t as difficult. My dashed lines gave me all the additionalreferences I needed. You can project lines between the top view and the side view to makesure that important reference points line up correctly. My side view outline is drawn below.

Page 175: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

With the top and side outlines finished, I can start drawing the fuselage bulkheads. Asbefore, we will use the side view to mark the top and bottom limits of each bulkhead and thetop view to mark the left and right limits of each bulkhead. Since the side view is now offset, wehave to project the top and bottom references over to the top view. The next several imagesillustrate this.

Because the side view is so foreshortened, it can be difficult to see exactly where thebulkhead lines should be drawn in the side view. You might find it easier to locate thebulkhead in the top view and then draw a line from the top view Y axis to the side view Y axisto determine where the first bulkhead will cross the side view Y axis. See the example below.

Page 176: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Next, in the side view draw the line to indicate where the bulkhead would appear. Itshould pass through the point on the Y axis indicated in the previous step. The first bulkheadis not perfectly vertical because the nose points downward a little bit. Once the bulkhead lineis drawn in the side view, you can see where it intersects the side view outline (indicated by thetwo small arrows in the image below).

The points where the bulkhead intersects the side view outline are the top and bottomlimits of the bulkhead. In the image below you can see I have drawn two parallel lines backover to the top view to show the top and bottom limits of the fist bulkhead.

Page 177: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Next, in the top view, note where the first bulkhead intersects the top view outline(indicated by horizontal arrows in the image below). Those two points are the left and rightlimits of the first bulkhead. I draw vertical lines through those points completing the box for thefirst bulkhead.

Below I have drawn the outline of the first bulkhead inside of that box.

Page 178: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Repeating the same process I have drawn the second bulkhead in the image below.

I think you get the idea. Below are the next two bulkheads.

The final bulkhead is in the image below. I’ve added some extra references for theexhaust nozzles and the tail boom. The exhaust nozzles are circular and I estimated theshape of the tail boom bulkheads.

Page 179: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

To help visualize the upper surface of the fuselage, I have highlighted the portion ofeach bulkhead that would be visible from our point of view in the image below.

Page 180: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

To draw the fuselage silhouette, I connect the edges of the bulkheads in the nose usingthe top view outline to get the curvature of the line. In the tail I have followed the top viewoutline and the tops of the bulkheads to determine the silhouette there. This is shown in theimage below.

Next, I draw the cockpit canopy. To help me place this correctly, I draw some referencelines using the top and side view drawings. Using my artist vision, I visualize the cockpit’sshape as you can see below.

To finish the fuselage, I just need to add the engine intakes. Using the side viewscaffold, I project the bottom edge of the engine intakes across to my drawing. I estimate thespacing of the vertical reference lines from the front view. You can see in the drawing below

Page 181: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

that the lower outer corners of the intakes are visible on each side of the LERX from our pointof view.

Below I have drawn the visible corners of the engine intakes.

Step 6: Outline and Shape the Wings and Tail

To draw the vertical tail, I draw some reference lines from the side view. Usingreferences in the top view outline, I draw two narrow triangles. This is shown in the imagebelow.

Page 182: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Outlining the wing and horizontal tail surfaces is very easy because we just have totrace the scaffold. The only thing I have to do is to clip the ends of the stabilators as you cansee below. I don’t really need to shape the wings. The upper surfaces only have a slightcurvature. Any appearance of curvature will be conveyed by a slight curvature of some of thepanel lines and by shading.

Below is my drawing so far. I have left the bulkhead reference lines in place becausethe shape of the upper surface of the fuselage is fairly complex. The reference lines help meto visualize it accurately as I add panel lines and final details.

Page 183: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Step 7: Clean up and Final Details

Below I have added the panel lines and final details. You can see that the panel linesreally help to define the shape of the fuselage. The bulkhead lines helped me to draw themcorrectly. Some good photographic references are also useful for insuring the final drawing isaccurate.

So what do you think? Is this not one of the coolest looking military jets in the world!?

Page 184: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Sketching the Flanker

Below is a sketch based on my black and white drawing. This camouflage patternconsists of a three-tone gray-blue pattern typical of these early generation Flankers. The nosecone is light gray. The stars on the wings are red with no white outline.

Because of the blended wing-fuselage design of this jet, it can be difficult to visualizethe patterns of light and shadow that would result from any particular point of light. This iswhere good reference photographs or plastic models can be invaluable. Using thosereferences, along with your understanding of the shape of the aircraft’s parts, you should beable to visualize how to shade your drawing.

I decided to have the primary light source (the sun) almost directly off of the left wing.Because of this, the upper surface of the wings and tail are shaded a little bit which helps toemphasize the light hitting the left side of the fuselage. The right side of the fuselage isilluminated with indirect light so it is not as bright, but still reveals the shape of the fuselage.With this kind of lighting, the shadows are going to be subtle.

Drawing Glass Canopies

Almost all aircraft have glass canopies or windscreens. Drawing glass can bechallenging for any artist. Because glass is transparent, drawing it can seem like trying todraw a picture of the invisible man! In fact, drawing glass is not that much different fromdrawing any other reflective surface.

To understand how to draw glass, I need to talk a little more about how light reflects offof surfaces. When light hits a reflective surface like glass, some of the light bounces off of that

Page 185: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

surface and some of the light is transmitted through it. The image below illustrates what I amtalking about. If you have ever seen your reflection in a window, you were seeing lightreflected off the surface of the window. The transmitted light goes through the window andilluminates whatever is on the other side.

As it turns out, the amount of light that reflects off of a surface depends on the angle atwhich the light hits the surface. This is illustrated in the next image below. When light hits thesurface at a very low angle, most of it reflects off of the surface and very little of it is transmittedthrough. The more light hits the surface at a perpendicular angle, the more it is transmittedthrough and the less it reflects.

You have probably experienced this phenomenon if you have ever looked out over abody of water. If you look towards the horizon, the water is highly reflective. If the water iscalm, it will act like a mirror reflecting the images of trees, hills, and clouds beyond. If you lookstraight down into the water, however, there is much less reflected light, and you can seethings under the surface of the water. The image below shows you why this is happening.From a single point of view, the more you look towards the horizon, the more you are seeingreflected light.

Page 186: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Now, imagine looking at a curved reflective surface like the canopy of an airplane. Thesame rules apply to curved surfaces as illustrated in the image below. The more the curvedsurface is oblique to your point of view, the more it will reflect light and the less transparent itwill be. The more the surface is perpendicular to your point of view, the less it will reflect lightand the more transparent it will be.

Now I’m going to show you how to apply these principles of reflection to drawing acanopy. Below is a drawing of the canopy of the Flanker. The point of view is slightly in frontand to one side. Let’s think about which parts of the canopy are most oblique (and thereforewill be most reflective) and which parts are most perpendicular to our point of view (andtherefore will be most transparent).

Page 187: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

The image below shows how reflection changes over the canopy from our viewpoint.Starting at the top of the canopy, we know that this will be most oblique to our point of view. Ifthe plane is flying upright, it will reflect the sky above. Next, think about the front part of thecanopy. That surface will be most perpendicular to our point of view and so it will be the mosttransparent part. Finally, the bottom edge of the canopy will also be somewhat oblique to ourpoint of view and so it will be more reflective. If the plane is flying upright, it will tend to reflectthe horizon.

Now that we have an understand about how light will reflect off of the canopy, we haveto understand what kind of environment our canopy and airplane are going to be drawn in sothat we can determine how the reflections will look. I’m going to show you three differentexamples to give you an idea of how this works.

In the first example below, I have drawn the canopy on a bright sunny day with blue skyabove and white clouds below. The Sun is in front of us so we don’t see specular lightreflected off of the canopy. Notice that the top edge of the canopy is dark. That’s because it isreflecting dark blue sky. The bottom edge of the canopy is light because of the reflected whiteclouds towards the horizon. The shapes seen through the canopy show more or less contrastdepending on how transparent the glass appears. Because the near side of the canopy is in ashadow, reflected light is more noticeable.

Page 188: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

The next image below is an example of the canopy on an overcast day. In this case thesky above tends to be light and the horizon is dark, the opposite of what we had in the drawingabove. So, that means that the top of the canopy is going to appear lighter because it reflectsthe lighter sky and bottom of the canopy is going to appear darker because it is reflecting thedarker horizon. Also, overcast days create diffuse light which means that there is generallymore reflected light over the whole canopy. This makes it harder to see details inside thecanopy so they are washed out with less contrast.

In our final example below, I’ve drawn the canopy with the light source behind us. Thiscreates a bright, distinct specular reflection. In this example there is a blue sky above and sothe top of the canopy appears darker but because we have a strong light source behind us,reflected light is less noticeable than in the first example (where the foreground was shaded).This means that the interior of the cockpit is seen in much more detail with good contrast.

Page 189: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Hopefully this section has taken some of the mystery out of drawing glass canopies. Asyou can see, it really just entails applying an understanding of how light, shadow, and reflectionwork. The same principles apply to drawing any reflective surface whether it is transparentglass or a solid surface. The best way to learn about light, shading, and reflection is to payattention to how light reflects off of everything you see. Try to understand what you are seeingin terms of what I’ve taught you. There is no better way to improve your artist vision than bybeing a careful observer of the world around you.

Russian Knights

In this final exercise, I’m going to show you how to draw a formation Su-27s with themarkings of the Russian Knights. The Russian Knights are the aerobatic demonstration teamof the Russian Air Force. They fly both single (SU-27S) and tandem (SU-27UB) seat Flankersthough in my drawing I’m only going to include the single seat version.

To determine where to place all the aircraft, I have created a reference grid for thewhole formation. In the image below, you can see what this looks like. The four aircraft will bein a diamond formation. Each of the individual jets will have a reference grid inside of the largerreference grid.

Page 190: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Each side of the four smaller reference grids is 2 ½ grid squares long. To draw them, Ijust have to estimate the spacing of the outlines of the smaller squares using the gridlines ofthe larger square. This is shown in the image below.

Below you can see how I have constructed this FRG. I am going to show the formationfrom above and slightly behind so the planes will be flying towards the right side of the page.This view really shows off the beautiful shape of the Flanker.

Page 191: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Below are the top view scaffolds. I have added the ovals after drawing the referencegrids. With a little trial and error, I got them properly oriented inside each reference grid. Thisgives me an idea of how much these four Z axes converge (to allow me to do a three pointperspective drawing). Because I am using a zoomed in view, there is not a lot of convergenceof these Z axes, but it is just noticeable. I’m not sure if it is enough to make a difference in thefinal drawing, but I needed to draw the ovals to estimate the foreshortening of my Z axesanyway. You can also see that I have drawn the side view reference grids.

Below is a close-up of one of the completed scaffolds with the wings and tail projectedto their correct locations. It is fairly simple, mostly made up of triangles.

Page 192: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Below is the finished outline of one of the Flankers. Because I have a good idea of theshape of the bulkheads, I don’t need to draw them. I can use my artist vision to see theshape. Once I add the markings and shading, the shape will become much more apparent.

Below is my finished sketch. I have placed the primary source of light above and infront of the viewer. This creates shadows on the near side of the aircraft. I did this because Ifelt that shading would help to more clearly define the shape of the fuselage. With the sun inthat position, sunlight would also be reflected by water (the formation is flying over a riverdelta), so the water is brighter than the ground. If the sun was behind the viewer, the waterwould have a bluer, and therefore darker, appearance. It is important to make sure that yourlight source is consistently applied across the whole drawing.

Page 193: Gregory A. Goodwin A Seven Step Process for Drawing ...dl.booktolearn.com/ebooks2/art/drawing/9781540389084_The...Sketching the Piper Cub Shading, Light, and Reflection The J-3 Grasshopper

Below is a close up of one of the aircraft. The markings of the Russian Knights are quitecolorful, and they have used a variety of paint schemes over the years. In the one I haveselected, the leading edges of the wings and tail have bright red stripes. The upper wingsurfaces have a blue/gray camouflage pattern. The vertical tail banners have a blue andyellow sunburst pattern with a red star in the center. The underside is blue and the nose iswhite. The close-up picture below helps you to see this in more detail (in black and white atleast).

Just like people, aircraft look better from some points of view than others. I think thispoint of view is definitely one of the SU-27’s most flattering. It really show’s off its distinctiveand beautiful shape. As you look at this plane, you should realize that it represents thousandsof innovations, large and small, learned over the last century of flight. It is truly a marvel ofmodern technology.

So Grasshopper, we have come to the end of this book and I will leave you with onefinal thought. The art of drawing airplanes is about portraying all of the emotions that theseflying machines evoke: a sense of awe, excitement, admiration, pride, inspiration, and manyothers. Now, go forth and draw magnificent airplanes!

EpilogueWherever you are in your development as an artist, I hope this book has helped you

out. Writing it has been a wonderful learning experience for me too. As much as I’ve covered,there are still many topics I could discuss and tricks and tips I could share. My hope is thatI’ve given you enough to get you started drawing really great airplanes.

To master this technique, you’ll have to practice it. Find some 3-view drawings ofplanes you love and try to draw them. Don’t get frustrated if your first few efforts don’t workout. Try to figure out what went wrong and try again. The more you practice it, the easier it willget. Don’t be afraid to modify this scaffolding technique to suit your own style. In fact, if youdiscover any great shortcuts, please share them with me. I’d love to learn from you too!

You can find free resources at my website: www.greggoodwinstudio.com to help you asyou learn to draw airplanes. There are videos and workbooks you can check out. Check backperiodically because I am always adding new things. If you have any questions, contact me [email protected].
