Aerodynamics Flashcards
Four Forces of Flight
1
Q
What are the four forces of flight?
A
- Lift
- Weight
- Thrust
- Drag
2
Q
What is lift?
A
Upward force created by the wing shape and airflow, counteracting weight.
3
Q
What is weight?
A
Downward force due to gravity
4
Q
What is thrust?
A
Forward force produced by the propeller and engine, overcoming drag.
5
Q
What is drag?
A
Air resistance opposing thrust.
6
Q
What is Bernoulli’s Principle?
A
Faster airflow over the curved top of the wing reduces pressure, creating lift.
7
Q
What is the angle of attack?
A
The angle between the wing’s chord line and the oncoming air. Increasing it increases lift up to a point before causing a stall.
8
Q
When do stalls occur? How do you recover?
A
When the angle of attack exceeds the critical angle, causing a rapid loss of lift. Recovery involves lowering the nose and adding power.
