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. Design machines that fly.






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






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






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






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






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






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






8. 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.






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






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






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






12. 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.






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






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






15. Robotic aircraft - used extensively by the military.






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






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






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






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






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






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






22. Aircraft speeds between Mach 1 and 5.






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






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






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






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






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






28. Aircraft speeds between Mach 5 and 10.






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






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






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






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






33. Aircraft speeds between Mach 10 and 25.






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






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






36. Aircraft speeds under Mach 1.






37. To set or thrust in motion.






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






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






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






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






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






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






44. 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.






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






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






47. The ratio of inertial forces to viscous forces.






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






49. 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.






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