1. INTRODUCTION• In our day to day life ,we are busy in our whole day tight schedule. But

sometimes when we look around to the sky,we see numbers of planes,aircraft,flying machine, helicopter, etc.• At that time we might be in confusion that how they works,what

exactly happening there?

• So this presentation is your answer. Here we will study all important short terminologies regarding to plane and clarification about its parts with corresponding function.

2. Parts of plane

3. AERODYNAMIC FORCES1. Thrust is the force that propels a flying

machine in the direction of motion. Engines produce thrust.

2. Drag is the force that acts opposite to the direction of motion. Drag is caused by friction and differences in air pressure.

3.Lift is the force that acts at a right angle to the direction of motion through the air. Lift is created by differences in air pressure.4.Weight is the force of gravity. It acts in a downward direction—toward the center of the Earth.

4. How Thurst produceThrust is a mechanical force which is generated through the reaction of accelerating a mass of gas, as explained by Newton's third law of motion. A gas or working fluid is accelerated to the rear and the engine and aircraft are accelerated in the opposite direction.

4.2. How Lift produce1. Lift is the force that directly opposes the weight of an airplane and holds the airplane in the air. Lift is generated by every part of the airplane, but most of the lift on a normal airliner is generated by the wings. Lift is a mechanical aerodynamic force produced by the motion of the airplane through the air.

2.The force (called lift) that enables an airplane to fly is produced by the application of a physical principle Called “Bernoulli’s Law of Differential Pressure,” or simply Bernoulli’s Principle, it states that as the speed of a fluid increases, its pressure decreases.

5. Axes of motion of Plane

5.2. Plane parts which lead to directional change

• control surfaces and the resulting motion of the aircraft:

• Elevator controls pitching motion.• Rudder controls yawing motion.• Ailerons control rolling motion.

6. Classification based on speed1. General aviation :-Speed (100-350 MPH)2. Sub –sonic :-Speed (350-750 MPH)3. Super-sonic :-Speed (760-3500 MPH)4. Hyper-sonic:-Speed (3500-7000 MPH)
