Arbitrary airfoil shape analisys for aeronautics Aeronautic students, engineers, RC hobbist or any one who loves airplanes. Here is the finest implementation of the Vortice Panel Method for arbitrary airfoil analysis available on the net. Calculate aerodynamic coefficients, plot velocity and pressure distributions, plot cl,cd,cm v/s angle of attack, import and export, etc.., all with a very nice graphical interface, never seen in windows.
