I recently found this reference to profile redesign in this forum. There the process of manually fairing the Selig coordinates of a wing profile is documented in order to end up with a perfect curvature profile.
I then made a pilot study to compute such curvature perfect profiles using automatic nurbs approximation using degree 5 nurbs with the same accuracy as in the article, replacing the manual conversion. This proved to be quite sucessful. The example from the article above
I then used the same technique on RG15 and Wortman FX-63-126 and constructed a wing section between the two optimized profiles. I know this combination is aerodynamically nonsense. Its only for illustration of the technique.
the 3dm file can be downloaded for inspection from here:strak from RG15 to FX-63-126
Do you think there is a need for such sophisticated curve smoothing in Rhino?
