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 under Mach 1.






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






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






4. 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.






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






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






7. A powered heavier- than - air aircraft with fixed wings from which the aircraft derives most of its lift.






8. To set or thrust in motion.






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






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






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






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






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






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






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






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






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






18. 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.






19. Aircraft speeds between Mach 1 and 5.






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






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






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






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






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






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






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






27. Design machines that fly.






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






29. Robotic aircraft - used extensively by the military.






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






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






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






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






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






35. The art and science of designing - building - and operating manned or unmanned space objects






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






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






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






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






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






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






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






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






44. 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.






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






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






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






48. Aircraft speeds between Mach 10 and 25.






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






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