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






2. Aircraft speeds between Mach 10 and 25.






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






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






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






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






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






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






9. 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.






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






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






12. Aircraft speeds between Mach 1 and 5.






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






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






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






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






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






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






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






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






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






23. 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.






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






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






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






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






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






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






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






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






32. 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.






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






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






35. 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.






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






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






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






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






40. Design machines that fly.






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






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






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






44. A glider designed for sustained flight.






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






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






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






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






49. Aircraft speeds under Mach 1.






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