Hydrodynamic and Aerodynamic Tests of a Family of Models of Seaplane Floats with Varying Angles of Dead Rise - N.A.C.A. Models 57-A, 57-B, and 57-C
This is an N.A.C.A. technical report from 1939 testing seaplane float hull models with varying deadrise angles, issued by the National Advisory Committee for Aeronautics for aircraft engineers. The four pictures are dense engineering charts with plotted curves of resistance, trim and load coefficients against speed and wave conditions, arranged on gridded white pages with fine labelled lines, which a designer might take as a study in layered technical graph layout and restrained monochrome data plotting.
