Maximum lift coefficient with respect to stall velocity Calculator

The maximum coefficient of lift (CLmax) is the highest or peak value of the coefficient of lift (CL) that an aerodynamic object, such as an airfoil or wing, can generate under specific conditions. It represents the maximum lift force that the object can produce relative to its properties and the flow conditions. CLmax is achieved when the aerodynamic object operates at a specific angle of attack (the angle between the chord line of the airfoil and the direction of the relative wind). At this particular angle, the airflow over the lifting surfaces remains attached, and the lift generated is maximized. 

  • CLmax: Maximum coefficient of lift
  • W: Weight of the  aircraft
  • ρ∞: Freestream density
  • Vstall: Stall speed
  • S: Reference area
