Xfoil

XFOIL
Written in Fortran
Website /xfoil/web/Public/drela.edu.mitweb

XFOIL is an interactive program for the design and analysis of subsonic isolated airfoils. Given the coordinates specifying the shape of a 2D airfoil, Reynolds and Mach numbers, XFOIL can calculate the pressure distribution on the airfoil and hence lift and drag characteristics. The program also allows inverse design - it will vary an airfoil shape to achieve the desired parameters. It is released under the GNU GPL.

History

XFOIL was first developed by Mark Drela at MIT as a design tool for the MIT Daedalus project in the 1980s.[1] It was further developed in collaboration with Harold Youngren. The current version is 6.99, released in December 2013. Despite its vintage, it is still widely used.[2]

XFOIL is written in FORTRAN.
