1.) True statements regarding the four forces of flight;
- The four forces are in equilibrium during unaccelerated flight.
2.) Refer to the following illustration and identify the aerodynamic terms associated with the airfoil.
A - Upwash
B - Leading Edge
C - Trailing Edge
D - Downwash
E - Flight Path
F - Relative Wind
G - Camber
H - Chord Line
I - Angle of Attack
3.) Describe how Newton's laws of motion and Bernoulli's principle explain the generation of lift by an airfoil.
- Bernoulli; increase in speed of air on the top on an airfoil produces a drop in pressure and the lowered pressure is a component of total lift.
- Newton; how the action of downwash and the airstream striking the lower surface of the wing results in a reaction of positive lift.
4.) As airspeed increases, the angle of attack at which an airfoil stalls also increases.
- False.
