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

Software
xfoil.tar.gz (435936 bytes)
Xfoil 6.94 for Unix and Win32. Gzipped directory tar image.
All source code, plain text version of User Guide, sample Xfoil session inputs.
Requires Fortran 77, C compilers, windowing support.
xfoilP4.zip (531947 bytes)
Xfoil 6.94 executable for Win32, optimized for Pentium 4.
Note: The source code for Xfoil itself is the same for Unix and Win32. The plot library directory (plotlib) has a separate win32 subdirectory. See all the README files for more info.
Win32 Notes: Interaction with Win32 XFOIL is through a DOS-type text console window. Some of Microsoft's Win32 OS'es (Win95/98/ME) have limitations on # of lines in a console window and cannot fully display XFOIL menus or output. Win95/98/ME also have other shortcomings with regard to resource usage and stability although XFOIL runs under these OS'es. Windows NT, Win2000 and Windows XP are the recommended Win32 platforms.
Win32 Exe Notes: The executables for Win32 were compiled using the Intel Fortran Compiler 5.01-15 and Visual C++6.0. The Intel compiler (thanks to Tom Clarkson at Intel) was used to optimize executables for P3 and P4 Pentium architectures. The XFOIL executables should run on any Win32 Pentium-class machine as compiler options were used to include both optimized code and generic Pentium or AMD processor code for portability.

天狼行空

Widows下不能使用，因为他的图像必须在UNIX环境下使用，所以一般爱好者使用用不了，这个软件是麻省理工大学航空系编写的一个计算低雷诺数翼型气动性能的软件，能使用的话功能还是很强的。
