McCarthy Machine Shop

Changes are coming to the McCarthy shop

You will need to have a TA with you to work in the machine shop area of McCarthy.

I’ve hired Manrique Rivas to work with Hong

They will make a schedule

Safety

In the assignments you will need to refine the safety documents from last semester.

Then you must follow your safety protocols and all University rules

The reason is that I really don’t want to see anyone injured, machinery is dangerous.

Hong, Manrique and I will cut a new sacrificial table and secure it to the mobile table

Material must be screwed down to the sacrificial table

If you have a prescription you must work with me to find something that work for you

Propeller Safety

You MUST wear leather work gloves

You MUST use at servo for the throttle control

You MUST wear safety glasses

You MUST NOT stand in the plane of the spinning prop

You MUST NOT run any engine inside a building

23

Most Important Things

There is not much time



Math is a must. But math and theory will get your plane off the ground.

You absolutely must make design decisions based on theory and be able to talk and write about that theory in a sophisticated wayThe plane you build be the plane in your design

24

Most Important Things

There is not much time



Engineering requirements and constraints are a must.

The SAE Judges will be looking for it

25

DesignPlease talk to Don, Ken, Hong, Manrique and me about fabrication

Show sketches of ideas and be able to explain that you are trying to do


26



Try to simplify your design for construction


27




Be sure you have thought through: Payload issuesMass distributionAssembly Servos

Van DriversEach team must have at least one CUA certified driver.

30

SyllabusThe syllabus is on the class webpage

http://faculty.cua.edu/vignola/Vignola_CUA/main_page.html

31

ThursdayThursday I will meet with each group

I will ask you to show me with drawings 1) How your subsystems are held together2) How your payload system works3) That you are ready to start building4) If you have a plan for purchasing components

32

Who is your driver?

33

Who is your driver?

Travis Bickly?

34

Who is your driver?

Each team will have their paperwork submitted before end of class

Van CertificationTo get van certified you need to email Andrew Wolfe

You have to re-certify if your were certified last year.

You have to fill out this formhttp://ehs.cua.edu/res/docs/CUA-Driver-Application-Summary-of-FCRA-rights-for-end-user.pdf

Everything is explained at http://pryzbyla.cua.edu/eventplanning/requests/Vancert.cfm

37

Duct tape and rubber bandsWork to simplify your designs

Your plane doesn’t need a door with hinges and a latch It doesn't need solid walls and shouldn’t be bigger that the stuff its carrying.

38

Duct tape and rubber bandsWork to simplify your designs

Think about how difficult it will be to build

Resolve Issues Between Subsystems

Whatever it takes

ServosPlease resolve all issues related to servos

41

ServosPlease resolve all issues related to servos. These include

46



Additional questions:Who is your van driver and have they started the process? Have you started making purchases? If not why not?

47




48




Don’t leave until we have had a chance to talk

Lets start with group 1

49

Assignment 1 Design Support 1) Gantt chart 2) Weight and drag budget 3) Cost budget 4) Parts inventory5) Toolbox inventory 6) Safety protocols

A timeline with milestones, component delivery dates, estimated dates of the completions of sub-tasks and dead line dates imposed by SAE and the syllabus.

50



A document that lists target, design and as-build weight and location for all components on the plane.

51




A list of all money spent by your group related to the project.

52




A list of all money spent by your group related to the project. There should be summary in the Word document and a separate Excel spread sheet. Include all items you plan to purchase and estimates of their cost.

53


A list of all purchased parts, and hyperlinks to data sheets. Be very specific.

54


A list of all purchased parts, and hyperlinks to data sheets. Be very specific.

Don’t say “motor”, “prop”. Choose the specific part that is needed and give the part number or exact name, determine how much monokote you need and be sure to include that.

55


A specific list of all tools, bolts and any other hardware with sizes.

56


A specific list of all tools, bolts and any other hardware with sizes.

Please don’t include anything general. For example “Allen wrench set” or “several screw drivers”. Separate out what you might need from what you do need for each specific bolt, screw or any other particular component.

57


List of all safety rules including the university’s new rules

This document must be signed by all team members.

58

Past Tenths / Future TenthsTask statements should be future tenths statement of what you will do.

The draft final report should only have past tenths statements of what you completed.

And be sure you do not include any speculation

Maybe, should be finished, likelihood

59

No Late SubmissionsI will not be giving extensions on the design support documents

Please plan ahead and submit on time

60

Writing Issues I have posted my document on writing “Writing issues for engineers”. I consider this a work in progress. Over the course of the semester I will add items to this document.

61


Use the “Writing issues for engineers” document as a checklist. Please use after you finish your first draft is assembled for all documents to be turned in for this class.

62


Use the “Writing issues for engineers” document as a checklist. Please use after you finish your first draft is assembled for all documents to be turned in for this class.

These ideas can and should be used for both PowerPoint presentations and written documents.

My Version

Plan what you need to say

Be clear

Be precise

Be specific, not abstract

Get to the point quickly

Focus on the most important things (aerodynamics, structure…)

Skip the little stuff (nuts and bolts,…)

63

64

Writing Check ListIssue 1: Use a template

65

Writing Check ListIssue 2: Use the spell check.

66

Writing Check ListIssue 3: Will the reader or recipient know what it is?

Identify your document with a descriptive title and an introductory sentence.

Assignment 2, Due ThursdayWork as a group and discuss safety issues with Ken and me.

Adapt your safety documents from last semester and get it approved on the spot.


69

First PresentationsWe will have the first set of presentations the second week of class.

Aim for 10 minutes and focus on fabrication

You should have no less that 10 PowerPoint slides

There should be figures and all slides


70

First PresentationsWe will have the first set of presentations the second week of class.

Talk about: How you are making the landing gearHow you are making the fuselageHow you are making the tailHow you are making the wingsWhat you need to purchase for each of these subsystemsWhat tools or machinery you needWhat you need from the machine shopWhat you need from the department

Please do not include discussion of safety issues
