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






3. To set or thrust in motion.






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






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






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






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






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






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






10. The ratio of inertial forces to viscous forces.






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






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






13. 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.






14. Aircraft speeds between Mach 10 and 25.






15. A glider designed for sustained flight.






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






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






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






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






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






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






22. Design machines that fly.






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






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






25. Robotic aircraft - used extensively by the military.






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






27. Aircraft speeds between Mach 1 and 5.






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






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






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






31. 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.






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






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






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






35. 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.






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






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






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






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






40. 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.






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






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






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






44. Aircraft speeds between Mach 5 and 10.






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






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






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






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






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






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