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 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.






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






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






4. Robotic aircraft - used extensively by the military.






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






6. The ratio of inertial forces to viscous forces.






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






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






26. Aircraft speeds between Mach 10 and 25.






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






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






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






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






31. Aircraft speeds under Mach 1.






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






33. To set or thrust in motion.






34. Aircraft speeds between Mach 5 and 10.






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






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






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






38. 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.






39. Design machines that fly.






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






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






42. 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.






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






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






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






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






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






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






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






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