Do 231
Role	VTOL transport aircraft Type of aircraft
Manufacturer	Dornier Flugzeugwerke
Status	Cancelled
Primary user	Lufthansa (intended)
Number built	0
Developed from	Dornier Do 31

Design and development

The Do 231 was a result of a design competition, conducted in the early 1970s by the German Federal Ministry of Economics, to create a 100-person VTOL aircraft. Based on the earlier Do 31, the Do 231 was to have shoulder-mounted cantilever swept wings and a T-tail.[1]

The 1973 oil crisis rendered the Do 231 proposal as uneconomical due to the high fuel consumption necessary for vertical takeoff and landing, and the aircraft was cancelled in 1976 without a single prototype being built.[1]

Variants

Do 231C: Commercial variant for Lufthansa with a capacity of 100 passengers.[1][2]
Do 231M: Military variant with a stretched fuselage and a rear loading ramp.[2]

Mit dem Projekt Do 231 V-Jet gewann Dornier Anfang der 1970er-Jahre einen vom deutschen Bundeswirtschaftsministerium ausgeschriebenen Entwurfswettbewerb für ein zukünftiges ziviles und militärisches V/STOL-Transportflugzeug für 100 Passagiere. Die Anforderungskriterien wurden von einem Sachverständigenausschuss unter Beteiligung der Ministerien für Wirtschaft, Verkehr und Verteidigung sowie von Experten der Luftfahrtforschung, der Lufthansa und der Industrie festgelegt.[1] Der von Dornier eingereichte Vorschlag fußte auf den Erfahrungen mit der Dornier Do 31.[2]
