xfoil 6.99 Program for the design and analysis of subsonic airfoils

XFOIL is an interactive program for the design and analysis of subsonic isolated airfoils. It consists of a collection of menu-driven routines which perform various useful functions such as:

  • Viscous (or inviscid) analysis of an existing airfoil

  • Airfoil design and redesign by interactive modification of surface speed distributions

  • Airfoil redesign by interactive modification of geometric parameters

  • Blending of airfoils

  • Writing and reading of airfoil coordinates and polar save files

  • Plotting of geometry, pressure distributions, and multiple polars
