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 10 and 25.






2. Design machines that fly.






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






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






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






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






7. 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.






8. 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.






9. Aircraft speeds under Mach 1.






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






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






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






13. To set or thrust in motion.






14. 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.






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






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






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






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






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






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






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






22. 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.






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






24. A glider designed for sustained flight.






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






26. Robotic aircraft - used extensively by the military.






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






28. Aircraft speeds between Mach 5 and 10.






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






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






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






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






33. 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.






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






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






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






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






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






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






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






41. The ratio of inertial forces to viscous forces.






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






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






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






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






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






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






48. Aircraft speeds between Mach 1 and 5.






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






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