Began construction of the first submarine of Russia
Almost 300 years ago a carpenter Efim Nikonov began construction 1 Russian submarine, which was made of wood. Days.Ru will tell about how illiterate peasant surprised ruler of the Russian Empire, Peter the great's own invention and what came of it.
The construction of submarines in the Russian Federation started with the petition to Peter the great in 1719. Peter received it from an illiterate peasant Efim Nikonov, who reported that he had invented a special vessel, which is able to sink a large number of enemy ships, and most importantly - it will go in the water secret".
Intriguing wording was intrigued by the ruler, and he called Nikonov long dialogue. Peter believed in the promise of the project and was ordered to urgently study. 1st submarine called "Secret ship" and even its very creation was carried out in absolute secrecy, as if saying, "openly the eyes of a stranger". In the decree of Peter was told to send the peasant "in the office of major-General Golovin to tell exemplary vessel to do...".
The creation of the vessel were held for a long time, a couple of years it was built by a carpenter, although Peter and gave him the best experts and almost unlimited resources. 1st test was 4 years after the start of the design, but the ship suddenly for all, the ship just sank into the deep, and from hitting the ground sharply beginning to fill with water. Inside were a Nikonov. Got him as a vessel, and the carpenter went on to finish his own submarine.
The system itself is meant the operation using the oars, and sank it, filling specialized bags with water. In order to float, the water had to be pumped out of these bags pump. The vessel according to one version resembled a barrel, and on other flat-bottomed boat with a roof". It even existed airlock to exit diver for the destruction of the bottom of the ship opponent.
Happened a few tests, but they were all unsuccessful. The boat did not want to be sealed. After the death of Peter the great, Catherine I gave the order to continue work on "hidden ship." As a result, after 8 years after the start of the project it was decided to collapse, and Nikonov demoted from masters in ordinary Admiralty staff".
Despite closed the project, the engineer E. Kolosov reports that Nikonov in action proved the possibility of diving: in the summer of 1721 Efim own "ship models" still made 2 good dives and surfacing on the Neva". And at the moment the model of the vessel is installed in Sestroretsk in the memory of the talented farmer-inventor.
