Complete tank tests of two flying-boat hulls with pointed steps - N.A.C.A. Models 22-A and 35
This is a 1934 NACA technical note from the NASA Technical Reports Server, reporting complete tank tests of two flying-boat hull models, 22-A and 35, with pointed steps, written for aeronautical engineers. Its four pages are dense engineering plots of resistance, trimming moment, and load on water against speed in feet per second, with parameter curves and labelled axes. A designer might take from them only a loose sense of the rising-then-falling curve families, since the content is technical data rather than imagery.
