The Dewoitine D 33 commercial airplane (French) : a low-wing cantilever monoplane
This 1931 NASA Technical Reports Server record is a technical report on the Dewoitine D 33, a French commercial airliner, presented as a low-wing cantilever monoplane for aeronautical engineers and researchers. The pictures are black-and-white plates of aircraft structure: wind-tunnel and hangar views of a fuselage and wing, numbered photographs of struts and framing, plus line drawings and an engine. A designer could take from them the dense, utilitarian look of early interwar aviation engineering documentation, with its grid layouts, numbered figure captions and industrial detail.
