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






2. The ratio of inertial forces to viscous forces.






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






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






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






6. Robotic aircraft - used extensively by the military.






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






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






9. 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.






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






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






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






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






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






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






16. To set or thrust in motion.






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






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






19. 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.






20. Aircraft speeds between Mach 10 and 25.






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






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






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






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






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






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






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






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






29. 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.






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






31. A glider designed for sustained flight.






32. The force that created by the effect of airflow as it passes over and under the wing.






33. Design machines that fly.






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






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






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






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






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






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






40. 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.






41. Aircraft speeds between Mach 1 and 5.






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






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






44. Aircraft speeds under Mach 1.






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






46. Aircraft speeds between Mach 5 and 10.






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






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






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






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