Airfoils and Wings | Panel Methods

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, allowing
    • forced or free transition
    • transitional separation bubbles
    • limited trailing edge separation
    • lift and drag predictions just beyond CLmax
    • Karman-Tsien compressibility correction
    • fixed or varying Reynolds and/or Mach numbers
  • Airfoil design and redesign by interactive modification of surface speed distributions, in two methods:
    • Full-Inverse method, based on a complex-mapping formulation
    • Mixed-Inverse method, an extension of XFOIL's basic panel method
  • Airfoil redesign by interactive modification of geometric parameters such as
    • max thickness and camber, highpoint position
    • LE radius, TE thickness
    • camber line via geometry specification
    • camber line via loading change specification
    • flap deflection
    • explicit contour geometry (via screen cursor)
  • Blending of airfoils
  • Writing and reading of airfoil coordinates and polar save files
  • Plotting of geometry, pressure distributions, and multiple polars
