Development of light and small airplanes
A 1926 NASA Technical Reports Server publication on the development of light and small airplanes, issued as a technical report for aeronautical engineers and researchers. Its pictures are plain photographs and line charts of aircraft such as the Junkers, Heinkel and Avro Baby, with a drag breakdown bar chart; a designer might take the clean, documentary style of the period's engineering plates and the simple chart of percentage drag by component.
