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






2. A glider designed for sustained flight.






3. Aircraft speeds between Mach 1 and 5.






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






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






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






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






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






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






10. 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.






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






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






13. Aircraft speeds under Mach 1.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






28. Aircraft speeds between Mach 10 and 25.






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






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






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






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






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






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






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






36. The ratio of inertial forces to viscous forces.






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






38. 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.






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






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






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






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






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






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






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






46. Aircraft speeds between Mach 5 and 10.






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






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






49. 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.






50. To set or thrust in motion.
