3. 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.

5. 3. AERODYNAMIC FORCES
1. 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.

6. 4. How Thurst produce
Thrust 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.

7. 4.2. How Lift produce
1. 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.

8. 5. Axes of motion of Plane

9. 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.

10. 6. Classification based on speed
1. 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)
