Stipa Monoplane with Venturi Fuselage
This is a 1934 NACA technical memorandum from the National Advisory Committee for Aeronautics, a government research report prepared for engineers and aircraft designers, describing the Stipa monoplane with its venturi-shaped fuselage. The pictures are plain black-and-white photographs with figure captions, showing the airframe from front, side and rear, the fuselage framework under construction, and wind-tunnel models of engine layouts. A designer could draw on their clean, technical, measured look for industrial or machine-age layouts.
