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. 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.






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






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






4. The ratio of inertial forces to viscous forces.






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






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






7. Aircraft speeds under Mach 1.






8. Aircraft speeds between Mach 5 and 10.






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






10. 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.






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






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






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






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






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






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






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






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






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






20. A glider designed for sustained flight.






21. Aircraft speeds between Mach 10 and 25.






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






23. 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.






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






25. Robotic aircraft - used extensively by the military.






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






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






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






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






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






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






32. 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.






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






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






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






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






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






38. 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.






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






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






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






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






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






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






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






46. Aircraft speeds between Mach 1 and 5.






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






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






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






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