Across
- 5. a measure of the curvature of the airfoil.
- 7. The rate of change of velocity with respect to time.
- 9. the controlling surface that regulates an aircraft’s roll.
- 10. Principle As the speed of a fluid increases, its pressure decreases.
- 11. control surfaces attached to the trailing edge of the wing extending outward from the fuselage to the midpoint of each wing. Flaps can increase the lifting efficiency of the wing and decrease stall speed.
- 12. A gas or liquid that tends to take the shape of its container.
- 13. The controlling surface that regulates an aircraft’s pitch.
- 15. The central body of an aircraft where wings and stabilizers are attached.
Down
- 1. an airplane with no attached source of thrust.
- 2. Angle The angle between an aircraft wing and a horizontal line.
- 3. The tail assembly of an aircraft, including the horizontal and vertical stabilizers, elevators, and rudder.
- 4. Resistance of the air (technically a fluid) against the forward movement of an airplane.
- 5. the width of an airfoil or wing.
- 6. Of Attack The acute angle between the direction of the relative wind and the chord of an airfoil.
- 8. A part or surface, such as a wing, propeller blade, or rudder, whose shape and orientation control stability, direction, lift, thrust, or propulsion.
- 14. Ratio The ratio between the wingspan and average chord of a wing.
