New Application of Principle of Variable-camber Airfoil : Lachassagne System
A 1924 NASA Technical Reports Server report on a variable-camber airfoil design, apparently prepared for aeronautical engineers and researchers. The single plate shows an airfoil profile drawn with ordinate scale, a table of angle-of-attack coefficients, and a dense grid of lift and drag curves with multiple axes, suggesting a technical chart for designers of wing shapes to reference.
