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 glider designed for sustained flight.






2. Aircraft speeds between Mach 10 and 25.






3. Aircraft speeds between Mach 5 and 10.






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






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






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






7. Design machines that fly.






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






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






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






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






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






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






14. 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.






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






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






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






18. To set or thrust in motion.






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






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






21. 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.






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






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






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






25. Robotic aircraft - used extensively by the military.






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






27. 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.






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






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






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






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






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






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






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






35. Aircraft speeds between Mach 1 and 5.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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