Xfoil
XFOIL is a widely used interactive program for the design and analysis of subsonic isolated airfoils. Developed by Mark Drela and Harold Youngren at MIT, it is primarily used by aerodynamicists and engineers to predict airfoil performance. The program can calculate the lift and drag coefficients for a given airfoil shape at a specified Reynolds number and Mach number.
XFOIL's core functionality lies in its iterative inverse design method and direct analysis capabilities. The inverse
The program is known for its ability to handle laminar and turbulent boundary layer calculations, including
