The Dewoitine D.332 commercial airplane (French) : a three-engine all-metal low-wing monoplane
This is a 1933 NACA aircraft circular from the NASA Technical Reports Server, written for aeronautical engineers and researchers, describing the Dewoitine D.332, a French three-engine all-metal low-wing airliner. The pictures are plain line drawings of its structure: three-view plans, wing and fuselage cutaway sections, landing gear, and fittings, all in a technical engineering style that a designer could use for mechanical detail, period diagrams, or vintage aviation graphics.
