General Potential Theory of Arbitrary Wing Section
This is a 1934 NACA technical report by the National Advisory Committee for Aeronautics, issued through the NASA Technical Reports Server, presenting general potential theory for arbitrary wing sections for aeronautical engineers. The pictures are technical graphs and diagrams: line plots of velocity and pressure curves against chord position, a grid of paired theoretical and experimental pressure distribution charts over small airfoil outlines, and a geometric construction drawing of an airfoil with a large circle, labelled angles and a flow direction arrow. A designer could draw on their clean black line work, labelled grid layouts and precise geometric annotations for sparse scientific infographics.
