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






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






4. 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.






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






6. Robotic aircraft - used extensively by the military.






7. Aircraft speeds under Mach 1.






8. The common reference point for the three axes of the aircraft.






9. A straight line parallel to the length of the fuselage but that runs through the aircraft's center of gravity.






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






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






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






13. Forces and moments on the body caused by a disturbance tend initially to return the body toward its equilibrium position.






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






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






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






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






18. 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.






19. Aircraft stability is the characteristic of an airplane in flight that causes it to return to a condition of equilibrium - or steady flight - after it is disturbed.






20. To set or thrust in motion.






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






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






23. A rear horizontal stabilizer that controls up and down or pitching motion of the aircraft nose.






24. 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.






25. 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.






26. Aircraft speeds between Mach 10 and 25.






27. The written text of a play - film - or broadcast.






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






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






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






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






32. Design machines that fly.






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






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






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






36. The mounting of wings so that the wingtips and higher than the wingroot.






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






38. Branch of technology and industry concerned with aviation and space flight.






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






40. The force that created by the effect of airflow as it passes over and under the wing.






41. Aircraft speeds between Mach 5 and 10.






42. A short - easily- remembered slogan - verse - or tune.






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






44. Out of its own accord - an aircraft eventually returns to and remains at its equilibrium position over a period of time.






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






46. Caused by the separation of airflow from the wing's upper surface resulting in a rapid decrease in lift.






47. Forward- acting force which opposes drag and propels the aircraft through the air.






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






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






50. An aircraft that is designed to fly without an engine.
