Greetings,

I am trying to create standard airfoil sections in AutoBlade (e.g. C-Series parabolic arc camberline and NACA 65-Series). I realize the code does not have these definitions explicitly. However, I was wondering if anybody out there has created these (or other standard airfoils) using the parameters available so I don't have to reinvent the proverbial wheel.

u'd better use the Desing3D module of NUMECA, it can design a parameter airfoil sections, then u can import a target file which is contact your NACA 65-Series to fitting the parameter airfoil !

Thank you Joe, good thought. This one has actually been suggested to me earlier. My hesitation with this is that it requires redundant definition of the problem, i.e., · find airfoil geometry generation tool that can provide surface coordinates given camber, thickness distribution, and LE & TE radius · convert this to .geomTurbo format · import to AutoBlade · perform fitting to recover parameters · export back to .geomTurbo format

This would be a good approach if I know that I was going to go through substantial parametric design effort via AutoBlade and Fine/Turbo. However, in this case, my blades are loaded well within typical range of the 65-series airfoils (in cascade) and I am more interested in quantifying off-design performance.

I have thought about trying this approach to recover some "base" parameters to then use for a family of airfoils. However, the control of camber and thickness distributions is touchy enough already that I fear it would not be generally applicable to obtain expected shapes.

What do you think – have you tried this?
