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 5 and 10.






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






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






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






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






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






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






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






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






11. 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.






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






13. 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.






14. A glider designed for sustained flight.






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






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






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






18. The space in the fuselage of a small airplane containing seats for the pilot - copilot - and sometimes passengers.






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






20. 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.






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






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






23. Robotic aircraft - used extensively by the military.






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






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






26. Design machines that fly.






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






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






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






30. 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.






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






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






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






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






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






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






37. 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.






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






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






40. To set or thrust in motion.






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






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






43. Aircraft speeds under Mach 1.






44. Aircraft speeds between Mach 10 and 25.






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






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






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






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






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






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