Flight Tests on U.S.S. Los Angeles. Part I : Full Scale Pressure Distribution Investigation
A 1930 NASA technical report, Flight Tests on U.S.S. Los Angeles Part I, issued for engineers and aeronautical researchers, documenting full-scale pressure measurements on the airship's hull. The pictures are engineering charts: pressure curves plotted along the length and polar diagrams of hull cross-sections at frames 145 and 175, with shaded regions marking positive pressure against the contour. A designer might borrow the clean plotted line work, the grid paper and the labelled circular diagrams as a sober technical graphic.
