Aerodynamic Forces and Moments of a Seaplane on the Water
A 1933 NACA technical memorandum from the NASA Technical Reports Server, issued by the National Advisory Committee for Aeronautics for aeronautical engineers and researchers studying seaplane behaviour on water. Its pages are graphs of moment coefficients plotted against angle, alongside a diagram of a biplane seaplane with force axes and a rig for a rotating-disk test setup. Designers can take from it the sparse engineering-grid look, with plain black line plots, dashed and solid curve sets, and schematic axis drawings.
