![]() ![]() 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: Corrected NACA coordinates from Theory of Airfoil Sections (Abbott and.NACA Report 93 (1921) includes coordinates and wind tunnel data on. ![]()
