Tests of N.A.C.A. airfoils in the variable-density wind tunnel Series 43 and 63
This is a 1931 NACA technical report from the NASA Technical Reports Server, presenting wind tunnel test results for airfoil series 43 and 63 for aeronautical engineers and researchers. Its pictures are plain engineering charts of lift and drag coefficients plotted against angle of attack, alongside line drawings of airfoil cross-section profiles, offering a designer clean curves and thin symmetrical-to-cambered wing outlines to study.
