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






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






3. Aircraft speeds under Mach 1.






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






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






6. Aircraft speeds between Mach 10 and 25.






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






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






9. Robotic aircraft - used extensively by the military.






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






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






12. The ratio of inertial forces to viscous forces.






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






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






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






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






17. Design machines that fly.






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






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






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






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






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






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






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






25. Aircraft speeds between Mach 5 and 10.






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






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






28. 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.






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






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






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






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






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






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






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






36. 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.






37. 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.






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






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






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






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






42. Aircraft speeds between Mach 1 and 5.






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






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






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






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






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






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






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






50. A glider designed for sustained flight.
