Hi Guys (and Ms. Young) For anyone interested in the performance of various wing sections, the following software is really neat and easy to download and use. It has info on thousands of sections, I was amazed to find even the AS sections developed for the KR's included in the library.
http://www.profili2.com/eng/default.htm The basic program is shareware, and that is probably enough. I opted to send him $15 (he actually asked for a donation of something less) - in return he provided a key to use the full version 2.14. The software has its origins in aero modeling but I find it extremely useful for comparing sections and drawing out sections. Caters for Polars Cl; Cd; Cl/Cd; Cm; Alpha (Reynolds Number is a variable) Animated drawing of the Cp distribution of any airfoil (your choice of RN) through a range of Alpha (-8 to +13) proved interesting on the AS5046 - particularly with the exaggerated aft high point (bulge) at the bottom. I am curious as to how this will effects aileron control at high AofA - the 18% section could be even more interesting in this regard. Steve J
