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. The lift coefficient allows engineers and aerodynamicists to evaluate and compare the lift performance of different objects, aiding in the design and analysis of aircraft and other aerodynamic structures. The formula to calculate lift coefficient as follows:
Where:
- W is the weight in N.
- S is the wing area in m2.
- g is the gravity in m/s2.
- R is the Turn Radius in m.
- CL is the Lift Coefficient.
