Karman-Tsien rule Calculator

The Karman-Tsien rule, with respect to the pressure coefficient (Cp), relates to the behavior of the pressure distribution on an airfoil (or wing) as it experiences compressible flow at high speeds, particularly at transonic and supersonic speeds. It provides insights into how the pressure coefficient varies with the freestream Mach number (M∞) and helps identify critical Mach numbers and drag divergence Mach numbers.
