Aerospace Engineering

Subject : engineering
Instructions:
  • Answer 50 questions in 15 minutes.
  • If you are not ready to take this test, you can study here.
  • Match each statement with the correct term.
  • Don't refresh. All questions and answers are randomly picked and ordered every time you load a test.

This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. Aircraft speeds between Mach 1 and 5.






2. Aircraft speeds between Mach 10 and 25.






3. Aircraft speeds between Mach 5 and 10.






4. Mach. A decimal number representing the true airspeed relationship to the local speed of sound.






5. An advertising film which promotes a product in an informative and supposedly objective style.






6. Hinged main surface part that help control banking for a turn






7. Characteristic of the aircraft that permits you to maneuver it easily and allows it to withstand the stress resulting from the maneuver.






8. A built in twist in the wing so that the trailing edge at the wingtip is raised (Wash out) or lowered (Wash in). This significantly affects the slow flight and stall characteristics of the wing.






9. The tail assembly of an aircraft - including the horizontal and vertical stabilizers - elevators and rudder.






10. A force caused by the gravitational attraction of the Earth.






11. The capability of an aircraft to respond to your flight inputs - especially with regard to attitude and flight path.






12. Motion around the lateral axis caused by deflection in the elevator controlled by moving the yoke forward and aft.






13. Robotic aircraft - used extensively by the military.






14. 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.






15. The flat surfaces located behind the center of gravity tend to weathervane with the wind.






16. An aircraft with floats or skis instead of wheels - designed to land on and take off from water.






17. The part of the airfoil that meets the airflow first.






18. A thin layer of air next to the surface of an airfoil which shows a reduction in speed due to the air's viscosity.






19. The outline shape of a wing when viewed from above.






20. A rocket- launched spacecraft able to land like an unpowered aircraft - used for journeys between earth and craft orbiting the earth.






21. A sequence of drawings representing the shots planned for a film or television production.






22. A rear vertical stabilizer that controls side- to- side or yawing motion of the aircraft nose.






23. Generates the lifting force that helps the airplane fly when air flows around it.






24. A type of aircraft deriving both lift and propulsion from one or two sets of horizontally revolving rotors.






25. Rolling motion about the longitudinal axis caused by ailerons deflecting in opposite directions and controlled by twisting the yoke.






26. A short - memorable phrase used in advertising or associated with a political party or group.






27. The horizontal line that passes through the center of gravity of the aircraft - perpendicular to its flight path.






28. A straight line through the center of gravity of the aircraft and at 90






29. The last point on an airfoil that interacts with the airflow around the wing.






30. The movement about the vertical axis produced by the rudder and controlled by pedals.






31. The angle formed by the wing chord line and the relative wind.






32. A large bag filled with hot air or gas to make it rise in the air - with a basket for passengers hanging from it.






33. Consists of both the engine and propeller in a small airplane.






34. Houses the cabin - the cockpit and is a common attachment point for the other major components.






35. The distance from wing tip to wing tip of a wing planform.






36. Design machines that fly.






37. The study or practice of travel through the air.






38. The relationship between the length and width of a wing.






39. Aircraft speeds under Mach 1.






40. The ratio of inertial forces to viscous forces.






41. Any surface - such as a wing - which provides aerodynamic force when it interacts with a moving stream of air.






42. The study of forces and the resulting motion of objects through the air.






43. A power- driven aircraft kept buoyant by a body of gas (usually helium) which is lighter than air.






44. The rate at which temperature decreases with an increase in altitude.






45. A vehicle - missile - or aircraft which obtains thrust by the reaction to the ejection of fast moving exhaust from within a rocket engine.






46. Acts in the opposite direction of flight - opposes the forward- acting force of thrust - and limits the forward speed of the aircraft.






47. A reduction in the chord of a wing as measured from the root to the tip of the wing.






48. A powered - aerial vehicle that does not carry a human operator - uses aerodynamic forces to provide vehicle lift - can fly autonomously or be piloted remotely - can be expendable or recoverable - and can carry a lethal or nonlethal payload.






49. A structure that creates up and down forces at the tail to keep the fuselage aligned in pitch with the relative wind. The structure itself is horizontal while the forces it creates are vertical.






50. To set or thrust in motion.
