The Effect of a Flap and Ailerons on the N.A.C.A. M-6 Airfoil Section
This is a 1928 NASA technical report on aerodynamic testing of the N.A.C.A. M-6 airfoil, a wing cross-section, with flap and aileron settings; it was issued by the National Advisory Committee for Aeronautics for aircraft engineers and researchers. The pictures are line graphs of lift, drag, and rolling and yawing moment coefficients plotted against angle of attack and control deflection, offering a designer a clear grid-and-curve vocabulary for technical charts.
