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.
