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. Aircraft speeds under Mach 1.






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






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






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






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






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






7. 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.






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






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






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






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






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






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






14. Aircraft speeds between Mach 1 and 5.






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






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






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






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






20. Aircraft speeds between Mach 10 and 25.






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






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






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






24. Robotic aircraft - used extensively by the military.






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






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






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






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






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






30. The ratio of inertial forces to viscous forces.






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






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






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






34. 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.






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






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






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






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






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






41. 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.






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






43. A glider designed for sustained flight.






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






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






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






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






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






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






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