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






2. 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.






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






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






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






6. 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.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






27. Design machines that fly.






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






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






30. Robotic aircraft - used extensively by the military.






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






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






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






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






35. 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.






36. A glider designed for sustained flight.






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






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






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






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






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






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






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






44. To set or thrust in motion.






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






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






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






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






49. 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.






50. The ratio of inertial forces to viscous forces.
