08/31/2007. Remarks by Johan Visschedijk: "The Do 29 was sponsored by the Bundesministerium der Verteidigung (German Federal Ministry of Defense) to investigate various STOL/VTOL problems, as well as various engine installations. It was developed jointly by Dornier and the Deutsche Versuchsanstalt für Luftfahrt (German Aviation Laboratory).
The Do 29 was based on the Do 27 airframe and powered by two 270 hp Lycomoing GO-480-B1A6 engines under the wing, driving three-bladed pusher-propellers. The rear portion of the engine nacelles could rotate, so that the propeller shaft could be inclined 90º downward to provide a vertical thrust component during take off and landing. The new fuselage nose had a glazed cockpit were the pilot was seated on a Martin Baker ejection seat.
