Tank tests of a model of a flying-boat hull with a fluted bottom
This is a 1935 NACA technical report by the NASA Technical Reports Server records, issued for aeronautical engineers and naval architects, presenting tank test results for a model flying-boat hull with a fluted bottom. The pictures are plain engineering charts and drawings: resistance, trim and speed curves plotted on gridded paper, one sheet of hull lines with half-breadth, body plan and profile views, and small labelled graph lines. A designer might borrow the clean grid layouts, hand-lettered axis labels and thin technical line work as a vintage scientific diagram motif.
