Across
  1. 2. Smaller and lighter than longerons, these rigid components serve to fill in as stiffeners when riveted to fuselage and wing skin
  2. 5. Angle that the wing's imaginary line makes with the longitudinal axis of the aircraft
  3. 7. Airfoil sections may be tapered, twisted, or _____
  4. 8. Number of stresses an aircraft may succomb to
  5. 9. Controlled by elevator, providing longitudinal stability
  6. 12. The three axes of rotation act through this concentrated point (abreviated)
  7. 14. Imaginary straight line that passes through wing or airfoil from leading edge to trailing edge
  8. 17. What happens to lift as the AOA increases
  9. 18. Cause of some unsafe airport & shop environments and aviation catastrophes, like the Concorde Crash
  10. 19. If the control stick of an aircraft with properly rigged flight controls is moved to the left, the right aileron will move
  11. 21. Structural partitions placed throughout the fuselage and wings, separating aircraft and wing sections
  12. 23. If the control stick of an aircraft with properly rigged flight controls is moved rearward, the elevator will move
  13. 24. Angle formed by chord line and a line indicating direction of the relative airstream
  14. 26. Aerodynamic part of airfoil that determines the amount of turbulence or skin friction produced
  15. 29. An aircraft must have sufficient ____ to maintain a uniform flightpath and recover from the various upsetting forces
  16. 31. Structural partitions placed to prevent fire from crossing into the cabin
  17. 32. Ratio comparing wingspan to chord line, perhaps as a measurement of obtaining greater lift
  18. 34. Provides primary fuselage and wing structure, running longitudinally
  19. 35. Controlled by airlerons, providing lateral stability
Down
  1. 1. Term for a wing, or any aerodynamic surface that creates lift
  2. 3. A part of a wing's measurement of area, taken from wing root to tip
  3. 4. Its structure types include monocoque, semi-monocoque, and truss
  4. 6. Lift to drag ratio (L/D) is the measurement of a wing's _____
  5. 10. Shape of an airfoil or cambered surface
  6. 11. Flight control surfaces that helpt to streamline stability of movement of the aircraft
  7. 13. Part of airplane that provides lift
  8. 15. Pressure needed below the wing for lift to occur, as opposed to the pressure above the wing
  9. 16. Stress that resists squeezing force
  10. 20. Structural crosspieces that give the wing its cambered shape
  11. 22. Stress that resists tearing force
  12. 25. Stress that resists "pulling apart" force
  13. 27. Controlled by rudder, providing directional stability
  14. 28. Movement from leading edge to trailing edge, nose to tail, etc.
  15. 30. Stress that resists twisting force
  16. 33. Part of airplane that provides thrust, which is not considered a part of the airframe
