Pressure Distribution Over a Thick, Tapered and Twisted Monoplane Wing Model-NACA 81-J
This is a 1932 NACA technical report by NASA's Technical Reports Server archive on pressure distribution across a tapered, twisted monoplane wing model tested in a wind tunnel. Its pictures show wing templates, a model mounted in the tunnel, plotted pressure curves, and the test room, all aimed at aerodynamic engineers rather than general readers. A designer might take from them the crisp line-drawn wing plans and the pale, technical chart style typical of 1930s engineering documentation.
