Internal structure of semi-rigid airship. A semi-rigid airship is an airship which has a stiff keel or truss supporting the main envelope along its length. The keel may be partially flexible or articulated and may be located inside or outside the main envelope.
The Giant (Russian: Гигант) was a semi-rigid airship designed by engineers Alexander Kovanko and Athanasius Shabsky. It was the largest dirigible built in Russia. In subsequent years, no airships of this size were created. The largest airship built in Russia, the SSR W-6 (Osoaviakhim), had a volume of only 18 500 m 3.
The airship was built with a semi-rigid structure. The hull acts as a pneumatic support structure supported by rigid elements, today known as Tensegrity. The rigid structural components of the airship are the nose structure, the system shaft, the center shaft, the aft unit cross shaft and the stern pan with engine base.
The main types of airship are non-rigid, semi-rigid and rigid airships. [3] Non-rigid airships, often called "blimps", rely solely on internal gas pressure to maintain the envelope shape. Semi-rigid airships maintain their shape by internal pressure, but have some form of supporting structure, such as a fixed keel, attached to it.
In contrast to the Zeppelins, the Parsevals were non-rigid or semi-rigid airships, with little or no stiffening structure inside the fabric envelope. The Zeppelins had a rigid internal framework made of duralumin. Both types relied on hydrogen gas to provide lift. Diagram of an early Parseval airship.
The Zeppelin NT is a semi-rigid airship. It is unlike both the original Zeppelins that had a rigid skeleton and non-rigid blimps. It has an internal triangular truss made of graphite-reinforced plastic and three longitudinal girders made of welded aluminium which connect the triangular elements along the length of the frame.

Euro Airship is planning an around-the-world, non-stop flight with Solar Airship One. It would be the first flight to make the trip without using fossil fuels.
SSSR-V6 OSOAVIAKhIM (Russian: СССР-В6 Осоавиахим) was a semi-rigid airship designed by Italian engineer and airship designer Umberto Nobile and constructed as a part of the Soviet airship program. The airship was named after the Soviet organisation OSOAVIAKhIM. V6 was the largest airship built in the Soviet Union and one of the ...
