wing's airfoil what does it really means?
Interesting translation...not to dispute Mike (he knows more about this than I do), but it reads like the wing airfoil is thicker at the tip than the root (13.5% root, 16% tip) with a more forward peak thickness. That seems odd...why would that be?
For that matter, I can't really find an airfoil that looks like the tip section (16% thickness, 20% position), although I've only poked around a few minutes on the UIUC site...
