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






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






3. 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.






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






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






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






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






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






9. 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.






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






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






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






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






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






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






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






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






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






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






20. Aircraft speeds under Mach 1.






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






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






23. Robotic aircraft - used extensively by the military.






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






25. Aircraft speeds between Mach 5 and 10.






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






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






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






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






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






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






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






33. 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.






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






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






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






37. A glider designed for sustained flight.






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






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






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






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






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






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






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






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






46. Aircraft speeds between Mach 10 and 25.






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






48. 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.






49. Design machines that fly.






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