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.{{Cite web | url=http://web.mit.edu/aeroastro/news/magazine/aeroastro-no3/2006drela.html |title = MIT Aero-Astro Magazine - Mark Drela Profile}} 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.{{cite web|url=http://www.aoe.vt.edu/~mason/Mason_f/MRsoft.html |title=Aerodynamics and Aircraft Design Software |access-date=August 3, 2010 |url-status=dead|archive-url=https://web.archive.org/web/20100608184358/http://www.aoe.vt.edu/~mason/Mason_f/MRsoft.html |archive-date=June 8, 2010 }}

XFOIL is written in FORTRAN.
