The lift coefficient (“CL”) is a dimensionless quantity used in aerodynamics to describe the lift generated by an aircraft’s wings or airfoil. It relates the lift force produced by the wings to the dynamic pressure of the airflow and the wing’s geometric characteristics. The lift coefficient is a fundamental parameter that helps aerodynamicists and engineers understand and analyze an aircraft’s lift performance.Â
- CL is the lift coefficient.
- AR is the aspect ratio of the wing.
- CD,i is the drag coefficient associated with the wing’s induced drag.
- δ is the induced drag factor.
