The lift coefficient (c) is a dimensionless aerodynamic parameter that quantifies the lift-generating efficiency of an airfoil, wing, or other aerodynamic body in a fluid flow. It is a crucial parameter in aerodynamics and is used to describe the relationship between the lift force generated by the body and the various factors that influence lift production.
- is the lift coefficient, which quantifies the lift generated by the airfoil as it interacts with the airflow.
- is the angle of attack, which is the angle between the chord line of the airfoil and the direction of the oncoming airflow.
- is the angle of attack at which the airfoil produces zero lift (i.e., no net upward or downward force).
