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. Aircraft speeds under Mach 1.






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






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






4. 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.






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






6. Aircraft speeds between Mach 5 and 10.






7. A glider designed for sustained flight.






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






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






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






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






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






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






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






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






17. 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.






18. Design machines that fly.






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






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






21. Robotic aircraft - used extensively by the military.






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






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






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






25. To set or thrust in motion.






26. The ratio of inertial forces to viscous forces.






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






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






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






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






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






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






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






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






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






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






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






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






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






41. 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.






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






43. 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.






44. Aircraft speeds between Mach 10 and 25.






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






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






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






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






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






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