Downwash measurements behind wings with detached float
A 1931 NASA technical report, published in the NACA technical memorandum series, that presents downwash measurements behind wings carrying a detached float, aimed at aeronautical engineers. The pictures are line plots of flow angles and pressure profiles, with sketched wing and float outlines and dash-dot curves at labelled angles of 15, 20, 30, 45 and 60 degrees, plus dense technical graphs of total and static pressure.
