What Causes an Airplane to Fly?
3
Test Your Knowledge ! Match term with letter. Weight Drag Lift Thrust A_______ B________ C________ D________
4
Newton’s Third Law FFFFor every action there is an equal and opposite reaction. WWWWhat does this have to do with flight?
5
Thrust The goal of a jet engine is to produce thrust. The engine pushes air molecules out the exhaust end of the turbine to generate a high speed jet of exhaust gas. THRUST!
6
Thrust from the engine moves the airplane forward.
7
Drag As the plane moves forward the air around it creates a force called Drag. Drag resists the movement of the airplane.
8
Lift How does an airplane create lift? We can look to our fine feathered friends for the answer
9
Lift Air moves faster over the wing than underneath it. Because faster air exerts less pressure than slower moving air………………………..
10
Lift ……………....The pressure underneath the wings lifts the plane off the ground
11
Flight To stay in level flight the following relationships must be true; A) Lift = C) Weight B) Thrust = D) Drag
