Rolling Moments Due to Rolling and Yaw for Four Wing Models in Rotation
This NASA technical report from 1932 presents wind-tunnel test results on rolling moments for several wing models in rotation, written for aeronautical engineers and researchers. Its pages are dense line graphs plotting rolling-moment coefficients against a rotation parameter, with several curves per chart and symbol keys in the corners, plus one cutaway technical drawing of a streamlined fuselage-like body with internal mechanisms. A designer might take from these the clean, sparse plotting style, with thin black curves, labelled axes and small legend boxes that suggest a restrained scientific graphic language.
