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. Aircraft speeds under Mach 1.






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






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






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






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






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






8. 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.






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






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






11. 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.






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






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






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






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






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






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






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






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






21. A glider designed for sustained flight.






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






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






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






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






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






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






28. Aircraft speeds between Mach 1 and 5.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






43. Robotic aircraft - used extensively by the military.






44. Aircraft speeds between Mach 5 and 10.






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






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






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






48. To set or thrust in motion.






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






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