Pressure-distribution measurements on a tapered wing with a partial-span split flap in curved flight
A 1939 NASA technical report, a pressure-distribution study of a tapered wing with a partial-span split flap in curved flight, issued for aeronautical engineers and researchers. The pages are dense sets of plotted graphs showing pressure coefficient against chord position for numbered wing chords, with separate outer-span and inner-span panels marking upper and lower surface readings as open circles and crosses. A designer could take from them the plain grid-and-curve vocabulary of engineering data plots, with paired upper and lower traces, dotted measurement points, and stacked small multiples.
