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






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






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






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






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






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






7. 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.






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






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






10. Aircraft speeds between Mach 10 and 25.






11. Design machines that fly.






12. 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.






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






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






15. A glider designed for sustained flight.






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






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






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






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






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






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






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






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






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






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






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






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






28. 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.






29. Aircraft speeds between Mach 1 and 5.






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






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






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






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






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






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






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






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






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






39. To set or thrust in motion.






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






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






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






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






44. Robotic aircraft - used extensively by the military.






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






46. 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.






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






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






49. Aircraft speeds between Mach 5 and 10.






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