Tank Tests of Models of Flying Boat Hulls Having Longitudinal Steps
This NACA technical report from 1936, issued by the National Advisory Committee for Aeronautics, presents tank test results for scale models of flying boat hulls with longitudinal steps, written for aeronautical engineers and hydrodynamics researchers. The single page shows plotted graphs of resistance and trim against speed, with families of labelled curves for different loads and step configurations, giving a designer a sober, technical example of engineering chart styling: thin black axis lines, dense small-type legends, and clean sparse plotting.
