A Comparison of the Results from General Tank Tests of 1/6- and 1/12-full-size Models of the British Singapore IIC Flying Boat
A 1942 NACA technical note reporting general tank tests of scale models of the British Singapore IIC flying boat, issued by the NASA Technical Reports Server collection for aeronautical engineers and researchers. The pages are dense line graphs of trimming moment, resistance and drag plotted against speed in feet per second, with curves labelled by load on water and model scale. A designer could take from them the clean grid layouts, tidy black line charts and technical labelling typical of mid-century engineering reports.
