Use the potential flow, boundary layer, and other types of analysis methods to get main characteristics from scanned data of an airfoil. Obtain airfoil coordinates, perform calculations of the local, inviscid flow velocity on the surface of the airfoil, and have differential equations solved.

From the developer:
JavaFoil is a free program that enables you to perform airfoil analysis. the program takes a set of airfoil coordinates, it calculates the local, inviscid flow velocity along the surface of the airfoil for any desired angle of attack. It also solves a set of differential equations to find the various boundary layer parameters.
