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. Aircraft speeds between Mach 10 and 25.






2. 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.






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






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






5. Aircraft speeds under Mach 1.






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






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






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






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






10. Robotic aircraft - used extensively by the military.






11. Aircraft speeds between Mach 1 and 5.






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






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






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






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






16. Aircraft speeds between Mach 5 and 10.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






32. To set or thrust in motion.






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






34. The ratio of inertial forces to viscous forces.






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






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






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






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






39. Design machines that fly.






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






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






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






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






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






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






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






47. 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.






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






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






50. A glider designed for sustained flight.
