Some experiments on the slipstream effect
This is a 1937 aeronautical technical report from NASA's Technical Reports Server, presenting experimental results on slipstream effects over propellers and wings for engineers and researchers. The pictures are plotted graphs of propeller and tail performance curves, a bar-style lift chart, and a test apparatus sketch with figure captions, giving a designer a sparse, mechanical vocabulary of dashed and solid curves, grid paper, and labelled diagrams.
