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






2. Aircraft speeds under Mach 1.






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






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






5. A glider designed for sustained flight.






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






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






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






9. 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.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






24. Aircraft speeds between Mach 1 and 5.






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






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






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






28. To set or thrust in motion.






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






30. Aircraft speeds between Mach 5 and 10.






31. 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.






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






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






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






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






36. The ratio of inertial forces to viscous forces.






37. Design machines that fly.






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






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






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






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






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






43. Robotic aircraft - used extensively by the military.






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






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






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






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






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






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






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