Normal pressure tests on unstiffened flat plates
This is a 1944 NACA technical note from the NASA Technical Reports Server, presenting normal pressure test results on unstiffened flat plates for aeronautical engineers and researchers. The pages are engineering graphs and plate diagrams with rotated labels, sheet thickness curves, and deflection profiles. A designer could take from them the stark, schematic look of technical line drawings: grids of fine lines, tapering curves, and small labelled figures on plain white paper.
