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






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






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






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






5. Aircraft speeds between Mach 10 and 25.






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






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






8. 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.






9. Aircraft speeds between Mach 1 and 5.






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






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






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






13. A glider designed for sustained flight.






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






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






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






17. Aircraft speeds under Mach 1.






18. 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.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






33. The ratio of inertial forces to viscous forces.






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






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






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






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






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. Design machines that fly.






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






41. 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.






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






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






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






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






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






47. Robotic aircraft - used extensively by the military.






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






49. Aircraft speeds between Mach 5 and 10.






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