Calculation of the aerodynamic characteristics of tapered wings with partial-span flaps
This is a 1939 NACA report from the National Advisory Committee for Aeronautics, issued by the NASA Technical Reports Server collection, presenting calculated aerodynamic data for tapered wings fitted with partial-span flaps, aimed at aircraft wing designers and engineers. The pictures are dense engineering graphs of lift, drag and moment coefficients plotted against angle of attack and flap deflection, with curves labelled by wing shape and flap position, and dimensional sketches of airfoil sections; a designer might take from them only the graphic conventions of technical charts, such as ruled grids, labelled curve families and schematic wing outlines.
