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. The study or practice of travel through the air.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






23. 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.






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






25. The ratio of inertial forces to viscous forces.






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






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






28. 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.






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






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






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






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






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






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






35. Robotic aircraft - used extensively by the military.






36. 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.






37. 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.






38. Aircraft speeds between Mach 1 and 5.






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






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






41. To set or thrust in motion.






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






43. Aircraft speeds between Mach 5 and 10.






44. Aircraft speeds between Mach 10 and 25.






45. A glider designed for sustained flight.






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






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






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






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






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