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






2. 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.






3. 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.






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






5. Aircraft speeds between Mach 5 and 10.






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






7. Aircraft speeds under Mach 1.






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






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






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






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






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






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






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






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






16. Aircraft speeds between Mach 10 and 25.






17. 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.






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






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






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






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






22. To set or thrust in motion.






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






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






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






26. 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.






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






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






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






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






31. A glider designed for sustained flight.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






49. Aircraft speeds between Mach 1 and 5.






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