The lift coefficient is a dimensionless parameter in aerodynamics that quantifies an object’s efficiency in generating lift as it moves through a fluid, such as air. It is used to describe the relationship between the lift force produced by the object and factors like its shape, angle of attack, and airspeed. A higher lift coefficient is associated with an increased turn rate in aircraft. This is because the additional lift generated during a turn provides the necessary centripetal force for the curved flight path. The formula to calculate lift coefficient as follows:
- is the lift coefficient,
- is the weight in N,
- is the Turn Rate in rad/s,
- is the gravity in m/s,
- is the air density in kg/m3,
- is a load factor, and
- is the Wing area in m2.
