Hi, in some cases it is hard to get the exact position of the leading edge of a NACA profile, because the t-parameter (curve parameter) is not at 0.5 anymore. That is why I wrote a small feature which finds the t-parameter for the point which has the longest distance to the trailing edge. Furthermore I included a few lines in the feature to measure the elapsed time. This can be helpful to optimize your feature. (Thanks Stefan for this.) regards Carsten FindNacaStart.fdb FindProfileLeadingEdge.fdf -
Hello, I was wondering if there's a connection between LCF, area of WL, etc., in order to find out a proper distance from the transom (let's say) to the tangent point, from which the half entrance angle iE is measured. Sadly, I can't find any reference for this matter. See the attached image. Thank very much, Stefan
