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 under Mach 1.






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






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






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






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






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






7. 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.






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






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






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






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






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






13. 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.






14. Robotic aircraft - used extensively by the military.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






35. 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.






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






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






38. Design machines that fly.






39. Aircraft speeds between Mach 1 and 5.






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






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






42. Aircraft speeds between Mach 10 and 25.






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






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






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






46. To set or thrust in motion.






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






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






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






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