In aerodynamics, the lift coefficient (cl) is a dimensionless quantity that represents the efficiency of an airfoil or wing in generating lift. It quantifies the relationship between the lift force generated by the wing and certain aerodynamic parameters, such as the wing’s shape, angle of attack, and the properties of the fluid (usually air) it is moving through. The lift coefficient is a fundamental parameter used in aerodynamic analysis and design, particularly for aircraft, to predict and control the amount of lift that can be generated under different conditions. It is especially important for determining an aircraft’s performance during takeoff, landing, and various flight maneuvers.Â
