Aerospace Engineering

Subject : engineering
Instructions:
  • Answer 50 questions in 30 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. A straight line through the center of gravity of the aircraft and at 90






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






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






4. 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.






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






6. A glider designed for sustained flight.






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






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






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






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






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






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






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






15. 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.






16. Aircraft speeds between Mach 1 and 5.






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






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






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






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






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






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






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






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






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






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






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






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






29. 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.






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






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






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






33. Aircraft speeds between Mach 10 and 25.






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






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






37. To set or thrust in motion.






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






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






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






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






42. Aircraft speeds between Mach 5 and 10.






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






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






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






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






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






48. 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.






49. Design machines that fly.






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