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. To set or thrust in motion.






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






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






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






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






6. Aircraft speeds under Mach 1.






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






8. A glider designed for sustained flight.






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






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






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






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






13. Robotic aircraft - used extensively by the military.






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






15. The last point on an airfoil that interacts with the airflow around the wing.






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






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






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






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






20. 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.






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






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






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






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






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






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






27. Aircraft speeds between Mach 1 and 5.






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






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






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






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






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






33. Aircraft speeds between Mach 10 and 25.






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






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






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






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






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






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






40. 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.






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






42. 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.






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






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






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






46. Aircraft speeds between Mach 5 and 10.






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






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






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






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