Experimental verification of Theodorsen's theoretical jet-boundary correction factors
This is a 1934 NASA technical report, published in the United States, testing Theodorsen's theoretical jet-boundary correction factors against wind-tunnel measurements for aeronautical engineers. The plots show absolute lift coefficient against angle of attack, correction factor against tunnel-to-model width ratio, and drag and lift in grams against angle of attack. A designer might take from them the clean engineering plot style: fine grids, plain black linework, small open-marker data points with fitted curves, and labelled legends in a restrained technical hand.
