Full-Scale Wind-Tunnel Tests with a Series of Propellers of Different Diameters on a Single Fuselage
A 1931 technical report from the National Advisory Committee for Aeronautics (NACA, United States), issued for aeronautical engineers and researchers, presenting full-scale wind-tunnel tests of propellers of varying diameters mounted on one fuselage. The pictures are engineering drawings of propeller blade plan forms and airfoil sections, graph plots of thrust and power coefficients against advance ratio, and a photograph of a fuselage-mounted propeller rig in a large wind tunnel. A designer might take from them the stark monochrome line work, tabulated curves and tapered blade silhouettes as period technical graphics.
