Principles of Aerodynamics - Four Forces on an Aircraft Flashcards
1
Q
What are the four factors that affect aerodynamics?
A
Thrust, Drag, Lift, Weight
2
Q
Define Thrust
A
Thrust is the force that propels the aircraft forward
3
Q
Define Drag
A
The force that slows a plane down. It is the counterpart to thrust
4
Q
Define Lift
A
Lift is the force that sends a plane up into the sky.
5
Q
Define Weight
A
Weight is lifts counterpart and weighs the plane down
6
Q
Define Straight and Level Flight
A
Straight and level flight is also known as a flight that is in equilibrium, or in unaccelerated flight. It is when thrust=Drag, and Lift = Weight
7
Q
Equilibrium
A
Thrust=Drag. Weight=Lift
8
Q
Unaccelerated Flight
A
When the direction of the plane does not change nor does the speed in which the plane is. moving
