The Breguet 270 General-Purpose Military Airplane (French) : A Two-Seat All-Steel Sesquiplane
A 1930 NACA aircraft circular from the NASA Technical Reports Server, prepared for engineers and aviation specialists, describing the Breguet 270 French two-seat all-steel sesquiplane for general military use. The pictures are black-and-white photographs of the aircraft, plus plan and elevation line drawings showing the wing layout and fuselage profile, with close detail views of the undercarriage, wheels, struts and cockpit fittings. A designer could take from them the clean geometry of biplane wing bracing, the steel truss framework and the engineering line-drawing style.
