A Complete Tank Test of a Model of a Flying-Boat Hull - N.A.C.A. Model No.11
This is a 1933 NACA technical report presenting a complete tank test of a flying-boat hull model, published by the National Advisory Committee for Aeronautics for aeronautical engineers and naval designers. The pictures are plain engineering line graphs, with black curves plotting resistance and trim moment against speed in feet per second for several hull trim angles, on squared grids with labelled data points. A designer might take from them the clean, restrained conventions of mid-century technical charting, with dense multi-curve plots, small numeric axis labels and sparse annotation.
