Seen using the XFOIL GDES command after loading the airfoil. Attempting to analyze thisĪirfoil (file) will create a bogus airfoil shape in XFOIL, e.g. Workable solution to this 'feature'." For instance, the FX 76-120Īirfoil file begins with "FX 76-120". Will be interpreted as logical variables, defeating the Will also choke on airfoil names that begin with T or F. From XFOIL documentation verbatim: "Some Fortran implementations.Many of the airfoils in the database were smoothed by Selig, and these include 'sm' in the name. The code removes bad kinks in the airfoil surface curvature that can give rise to spikes (non-smoothness) in the velocity distributions.Īdded online at PDAS by Ralph Carmichael. For coordinates that are not smooth, the NASA AFSMO smoothing code (airfoil smoothing code) can be used to smooth the points.The original airfoils/coordinates do not, e.g. The coordinates give smooth inviscid velocity distributions, but some of Von Doenhoff) courtesy of Ralph Carmichael, PDAS:
