The Dornier Delphin (en: Dolphin) was a 1920s German single-engine commercial flying boat built by Dornier Flugzeugwerke. As well as commercial users single examples were acquired by the United States Navy and the British Royal Navy for evaluation. ==Development== The Delphin I was developed in 1920. It was an all-metal single-engine high-wing monoplane flying boat. It had an enclosed cabin for four-passengers with the wing mounted above and the nacelle-mounted engine above that. It was powered by a 138 kW (185 hp) BMW IIIa inline engine. The pilot had an open cockpit on the upper surface of the hull behind the engine which gave him a limited view forward. It first flew on the 24 November 1920. Dornier first tested the design concept and spontoons in place of wing tip floats with a small three seater named the Dragon Fly〔("The Dornier Dragon Fly Flying Boat" ) ''FLIGHT'', October 20, 1921〕 An improved version, the Delphin II first flew on 15 February 1924 and was powered by either a 186 kW (250 hp) BMW engine or a 194 kW (260 hp) Rolls-Royce Falcon III engine. The enclosed cabin now had room for two crew and five passengers. Following the success of the Delphin II a larger version the Delphin III was developed from 1927. It was powered by a 447 kW (600 hp) BMW VI engine and had a separate flight deck for the two-man crew and a cabin for 10 passengers. A Delphin I was acquired by the United States Navy and a Delphin III by the Royal Navy both of whom were interested in evaluating the metal construction. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Dornier Delphin」の詳細全文を読む スポンサード リンク
