Wind tunnel research comparing lateral control devices, particularly at high angles of attack VIII : straight and skewed ailerons on wings with rounded tips
This is a 1933 NACA technical report by the National Advisory Committee for Aeronautics on wind tunnel tests of aileron designs for aircraft wings, aimed at aeronautical engineers. Its plan-view drawings show wing tips with straight and skewed ailerons, with dimensioned sections and tables of station and ordinate values. A designer could take from them the clean, labelled technical line style of early engineering drawings, with measured outlines and dimension lines.
