Bf 108 wing profile
Thanks to Erl Cromie, I have found out that the profile for the 108 was NACA 2416 at the wing root, and NACA 2413 at the wingtip. This I have since confirmed through a manual on the a/c. Interestingly, I am finding that the last 2 letters of the NACA number stand for the wing thickness at that point, ie. 16% and 13%. So, what do the first 2 numbers stand for, simply the curve number?
Additionally, while Messerschmitt said the wing profile was 2R1 14.2 and 2R1 11, its full designation, according to Erl, was probably NACA 2314.2 and NACA 2311.
