Experimental Verification of the Theory of Wind-Tunnel Boundary Interference
This is a 1935 NASA technical report, published by NACA-era aeronautical researchers, presenting experimental checks of wind-tunnel boundary interference theory for aircraft engineers and wind-tunnel testers. The three plates are engineering drawings: a longitudinal section and plan of a wind tunnel with its flow, control and propeller arrangement, and a chart of pilot-head pressure ratios against angle of attack for several aircraft positions. A designer might borrow the crisp technical line drawings, dimension callouts and the grid-based plan layouts as austere diagram motifs.
