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. Robotic aircraft - used extensively by the military.






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






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






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






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






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






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






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






9. 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.






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






11. 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.






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






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






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






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






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






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






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






19. Aircraft speeds between Mach 1 and 5.






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






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






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






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






24. 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.






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






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






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






28. A glider designed for sustained flight.






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






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






31. Aircraft speeds between Mach 10 and 25.






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






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






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






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






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






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






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






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






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






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






42. Aircraft speeds under Mach 1.






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






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






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






46. Design machines that fly.






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






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






49. 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.






50. To set or thrust in motion.
