The airship is a romantic form of transport, which flourished in the 30s of the last century. But even at that time in the USSR there were much fewer such aircraft than in the countries of Europe and America.
It is all the more interesting to learn that the development of new models is still being carried out by a group of engineers and scientists. The research center has been based in Dolgoprudny for many years.
The principle of operation is based on the law of Archimedes. The lifting force is provided by the gas in the shell, which is lighter than air. The ratio of fuel consumption and payload for airships is the most economical. Even if you turn off the engine, nothing bad will happen.
In the Russian Federation, 11 aircraft of this type are used. The construction is reminiscent of tailoring a suit - according to the design of the designers, shell elements are cut out and welded, thanks to high-tech equipment, the seams are stronger than the material itself. And if earlier the dome was filled with explosive hydrogen, now safe helium is used.
To learn more about the new Russian airships and their characteristics, watch the video of the Strana TV channel. There is a lot of information for everyone who is interested in air transport.
