Thanks for this, it is very interesting and I'll carefully study your report and learn all I can from it.
In another thread
, we were discussing what an airfoil might look like if it was designed to produce maximum Cl at an Re of 35000, and if you really didn't care about Cd at all.
Would it be easy to to run an optimisation and see what it comes out with? The best we've seen so far is a Cl of 1.8 (or course the drag was terrible, but it's not important for this question).
