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






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






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






6. Robotic aircraft - used extensively by the military.






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






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






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






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






11. Design machines that fly.






12. Aircraft speeds between Mach 5 and 10.






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






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






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






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






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






18. Aircraft speeds between Mach 1 and 5.






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






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






21. A glider designed for sustained flight.






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






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






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






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






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






27. 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.






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






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






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






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






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






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






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






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






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






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






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






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






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






41. 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.






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






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






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






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






46. 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.






47. To set or thrust in motion.






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






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






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