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
A lifting body is a fixed-wing aircraft or spacecraft configuration in which the body itself produces lift. In contrast to a flying wing, which is a wing with minimal or no conventional fuselage, a lifting body can be thought of as a fuselage wi ...
airship concepts, where a craft without a conventional "wing" generates lift by itself. It would have also have been filled with buoyant gas such as preferably helium or hydrogen, but possibly heated gases, making it a truly hybrid craft. This kind of configuration was researched by Aereon beginning in the 1960s and continuing until the 1980s. Several patent applications were filed, including a patent application filed in 1969.
The early development of the deltoid pumpkinseed aerobody was described in a John McPhee 1973 book.
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
The AEREON 26 was an experimental aircraft developed to investigate lifting body design with a view to using its shape to create hybrid designs, part airship, part conventional aircraft. It was powered by a piston engine, driving a pusher propel ...
. 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:
* 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.

Navy and Air Force research
When it turned out that building the Dynairship under Aereon at that time was financially impossible, Miller went on to design very similar craft for research in the military field. The job of building a prototype craft was given to Lockheed's L-TAV division, and the resulting craft was named the STOL-340.
