The Effect of Spray Strips on the Take-off Performance of a Model of a Flying-Boat Hull
This is a 1935 NASA technical report, published by NACA-era aeronautical researchers, testing how spray strips on a flying-boat hull model affect take-off performance. Its pictures are engineering charts plotting resistance, trim angle, rise and moment against speed in feet per second for several beam widths and step angles, plus a grid of photographs of the model at different strip angles, useful to a designer for seeing how data curves and test-tank imagery are laid out.
