Lift
A force that enables an aircraft to rise off the ground.
2
New cards
Lift Formula
A mathematical representation of the lift force that relates various parameters affecting lift.
3
New cards
Mean Camber Line
The precise center of the wing's thickness when sliced in half.
4
New cards
Leading Edge
The point where the mean camber line meets the front end of the wing.
5
New cards
Trailing Edge
The point where the mean camber line meets the rear end of the wing.
6
New cards
Chord Line
A straight line joining the leading edge and trailing edge.
7
New cards
Relative Airflow
The direction of the air movement relative to the wing.
8
New cards
Angle of Attack
The angle between the chord line and relative airflow.
9
New cards
Airspeed
The speed at which the aircraft flies through the air.
10
New cards
Wing Surface Area (S)
The projected area of the wing.
11
New cards
Air Density (Rho aka ρ)
The mass of air molecules within a specific volume; higher density indicates more air molecules present.
12
New cards
Lift Force (L)
The force created by the wing's movement through the air.
13
New cards
Coefficient of Lift (Cl)
Represents how much lift the wing can produce at any position of the angle of attack; determined during wing design.
14
New cards
Key Variables affecting Lift
Angle of Attack
Air Density (ρ)
Airspeed (V)
Wing Surface Area (S)
