50 Aerodynamics Questions and Answers
1. What is aerodynamics?
Aerodynamics is the study of how air moves around objects, especially things like airplanes,
cars, and rockets.
2. What is airflow?
Airflow is the movement of air around an object when either the object or the air is moving.
3. What is lift?
Lift is the upward force that helps an airplane rise into the sky.
4. What is drag?
Drag is the force that pushes against an object moving through air, slowing it down.
5. What is thrust?
Thrust is the forward force created by engines or propellers that pushes an aircraft ahead.
6. What is weight in aerodynamics?
Weight is the force caused by gravity pulling an aircraft downward.
7. What is an airfoil?
An airfoil is the special shape of a wing that helps produce lift.
8. Why are wings curved on top?
The curved top speeds up the air, lowering pressure and helping create lift.
9. What is the angle of attack?
The angle of attack is the angle between the wing and the direction of the oncoming air.
10. What happens if the angle of attack is too high?
The wing may stall because smooth airflow breaks down.
11. What is a stall?
A stall is when the wing suddenly loses lift due to disrupted airflow.
12. What is Bernoulli’s principle?
, Bernoulli’s principle says that faster-moving air has lower pressure.
13. How does Bernoulli’s principle help wings fly?
Fast air on top of the wing creates low pressure, which helps lift the plane.
14. What is Newton’s third law in flying?
It explains that pushing air downward creates an upward reaction force called lift.
15. Why do planes need engines?
Engines provide thrust to move the plane forward and generate airflow over the wings.
16. What is a streamlined shape?
A shape designed to let air flow smoothly around it, reducing drag.
17. Why do birds fold their wings while diving?
They fold wings to reduce drag and increase speed.
18. What is laminar flow?
Laminar flow is smooth, organized airflow over a surface.
19. What is turbulent flow?
Turbulent flow is chaotic, swirling air that creates more drag.
20. What causes turbulence in flight?
Uneven air movement, weather changes, and obstacles in the atmosphere.
21. What is the purpose of flaps on a wing?
Flaps increase lift at low speeds, like during takeoff and landing.
22. What are slats?
Slats are devices on the front of wings that help create more lift at low speeds.
23. What is aileron?
Ailerons are movable parts on the wing that control roll (tilting side to side).
24. What is the rudder used for?
The rudder controls yaw, which is left or right movement of the nose.
25. What does the elevator control?
