KármánTsien
The Kármán–Tsien method is a technique used in aerodynamics to estimate the lift and drag of airfoils at transonic speeds. It was developed by Theodore von Kármán and Hsue-Shen Tsien in the late 1930s and early 1940s. The method is based on the idea of transforming a known airfoil's properties to predict the behavior of a different airfoil.
Essentially, the Kármán–Tsien method applies a compressibility correction to the incompressible flow solution. It uses a
The method's accuracy is generally good for thin airfoils and moderate transonic Mach numbers. However, its
