The Aereon Dynairship is a conceptual large hybrid airship developed by the Aereon Corporation for civilian and military cargo transport. It is one of Aereon's lifting body airship concepts, where a craft without a conventional "wing" generates lift by itself. It would have also have been filled with rising gas such as hydrogen, making it a truly hybrid craft. This kind of configuration was researched by Aereon during the 1980s. However, a patent was filed in 1969. ==Design and development== The Dynairship was to be a very large ship, the conceptual designs showing it to form a large triangle, with small finlets at the back of either end.〔 The proof-of-concept aircraft for the Dynairship was the Aereon 26. Following the apparent success of this project, Aereon's board voted unanimously to proceed with the Dynairship for civilian and commercial purposes. Three proposed versions of the Dynairship were put forward:〔Miller, pp. 455–6.〕 * A "small patrol aircraft" long, with a gross weight of * A "medium-size cargo aircraft" long, with a gross weight of * A "logistic carrier" long, with a gross weight of . Original propulsion was stated in the patent to be four externally mounted propellers on the top of the body, with engine nacelles. In the 1991 patent, a glass cockpit can be seen at the front.〔(Google patents - Patent 5,034,751 )〕 However, the Aereon corporation state that the design can be either manned or un-manned.〔 A lack of funding ended the project. According to Aereon, the Department of Defense told Miller in 2003, "You were 30 years ahead of your time"! 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「Aereon Dynairship」の詳細全文を読む スポンサード リンク
