A General Tank Test of a Model of the Hull of the British Singapore IIC Flying Boat
A 1936 NACA technical note from the NASA Technical Reports Server reporting tank tests of a scale model of a flying boat hull, the British Singapore IIC, written for aeronautical engineers and researchers. The three pages are engineering graphs: curves of resistance and trimming moment plotted against speed in feet per second, with parameter lines for load and trim angle, drawn on squared grid paper with lettered axis labels and figure captions. A designer could take the restrained grid-and-curve layout, the labelled axes and the clean monochrome line work as a model for technical diagrams.
