Drag measurements of two thin wing sections at different index values
A 1927 NASA technical report, compiled from the NASA Technical Reports Server, presenting aerodynamic drag measurements for two thin wing sections, aimed at aeronautical engineers and researchers. The two pictures are numbered line graphs plotting drag against a Reynolds-number axis, with curves labelled I, II and III and a legend of angle-of-attack markers; a designer could take from them the clean technical plotting style, with fine grid lines, varied marker symbols and labelled curve families.
