Calculation of Pressure Distribution on Airship Hulls
A 1930 NACA technical memorandum, number 574, issued by the National Advisory Committee for Aeronautics and preserved through the NASA Technical Reports Server, presenting calculated pressure distributions for airship hulls to engineers and aerodynamicists. The page is a dense technical plate of diagrams: a small airship cross-section with angle labels, a stepped graph of dynamic pressure against angle of flow, a tabulated chart of coefficients, and a source-distribution profile, drawn in fine black line on white with little tonal variation that a designer might borrow for schematic or blueprint-style graphics.
