Parseval Airships
The Parsevals were 22 airships built between 1909 and 1919 by the Luft-Fahrzeug-Gesellschaft (LFG) following the design of August von Parseval. In the 1920s and 1930s, three more airships were built following the Parseval-Naatz (PN) design. As with the rival Zeppelins, the airships were, in both English and German, referred to by the name of the inventor. (In German, the nouns were masculine, that is, "''der Parseval''", "''der Zeppelin''".) 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. Experimental airship The ''Versuchsluftschiff'' (meaning experimental airship) was Parseval's first model. It was rebuilt several times. *First flight on 26 May 1906 at Berlin's Tegel, a military field *Pilot: Captain von Krogh *Length: 48 m, Diameter: 4.8 m *Power plant: 6 ...

Airship
An airship or dirigible balloon is a type of aerostat or lighter-than-air aircraft that can navigate through the air under its own power. Aerostats gain their lift from a lifting gas that is less dense than the surrounding air. In early dirigibles, the lifting gas used was hydrogen, due to its high lifting capacity and ready availability. Helium gas has almost the same lifting capacity and is not flammable, unlike hydrogen, but is rare and relatively expensive. Significant amounts were first discovered in the United States and for a while helium was only available for airships in that country. Most airships built since the 1960s have used helium, though some have used hot air.A few airships after World War II used hydrogen. The first British airship to use helium was the ''Chitty Bang Bang'' of 1967. The envelope of an airship may form the gasbag, or it may contain a number of gas-filled cells. An airship also has engines, crew, and optionally also payload accommodation ...

Russian Airships
This article outlines some of the non-rigid and semi-rigid airships used in or built in Russia and the Soviet Union. Origins of the Soviet Airship Program Like other nations in the early 20th century, Russia began researching and developing its own airships. Despite heavy investment in industry by the Russians in late 19th and early 20th century, aviation received little in subsidies and relied heavily on foreign technologies. The Imperial Russian Air Service did not come into being until 1912, and though small fixed-wings airplanes were used in World War I, they were limited in their capabilities. Only after the October Revolution in the 1920s did airship enthusiasts begin constructing small non-rigid ships. The first Soviet airship to ever take flight was the Krasnaia Zvezda ('Red Star') which saw its brief maiden voyage on January 3, 1921. Soviet Airships Under Stalin Airships saw further development under Joseph Stalin during the First Five Year Plan. Impressed by ...
