Tests of a Wing-nacelle-Propeller Combination at Several Pitch Settings up to 42 Degrees
This 1937 NASA technical report presents wind-tunnel test results for a wing, nacelle and propeller combination at several blade pitch settings, prepared for aeronautical engineers and researchers. Its single picture is a line graph of thrust coefficient against advance ratio V/nD, with curves labelled by blade angle and a caption identifying a figure from the Langley series. A designer might take from it the clean, dense plotting style: thin black curves, dashed variants, fine tick labels and a dotted reference line, a useful model for technical chart aesthetics.
