Across
  1. 3. A measure of the curvature of the airfoil.
  2. 7. A chemical mixture that is burned to produce thrust.
  3. 8. The central body of an aircraft where wings and stabilizers are attached.
  4. 10. An aircraft of greater weight than the air displaced.
Down
  1. 1. An airfoil mounted on a revolving shaft. It creates low pressure in front of it, thereby moving an aircraft forward because of the high pressure area behind the propeller.
  2. 2. 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.
  3. 4. of Attack The acute angle between the direction of the relative wind and the chord of an airfoil.
  4. 5. The tail assembly of an aircraft, including the horizontal and vertical stabilizers, elevators, and rudder.
  5. 6. A part or surface, such as a wing, propeller blade, or rudder, whose shape and orientation control stability, direction, lift, thrust, or propulsion.
  6. 9. Resistance of the air (technically a fluid) against the forward movement of an airplane.
