The oceans await our "Lada"
Vladimir GUNDAROV, the "Red Star".
Already during October at the plant "admiralty shipyards" in the northern capital will pass the solemn ceremony of descent to the water of a new Russian diesel-electric submarine (SSK)"Saint Petersburg" of project 677 "Lada". On this reported the design project leader OF TSKB MT. "Rubin" Igor Spasskiy, association of which developed the design of this submarine.
"Saint Petersburg" - the first submarine is not only of a new project. It opens the line SSK of the fourth generation. Its generation, in the essence, breakthrough in the technical and economic characteristics and technology. In it are realized more than hundred new scientific and design solutions. Radio-electronic armament, boat equipment and materials - last word of science and technology. In the opinion of the creators of submarine, it is the pilot project of all SSK, which will be constructed in the new century.
Basic difference in the energy-armament of submarine - the so-called"hydrogen small batteries". This is main power plant (GEU) of the locked type, because of which in comparison with the traditional storage batteriesof diesel-electric submarines several times is increased theindependence.
However, Russian designers thirty a (!) years ago proposed GEU with the electrochemical generator (EKHG). Hydrogen and oxygen were used as the fuel cells in it. The submarine S -273 of project 613 they re-equipped on to project 6133 "Katran". If usual boats at binodal speed without the booster charge could befound under water not more than four days, that with the use EKHG period increased to the month. The creation of diesels became the second direction in the designdevelopments, working on the closed cycle. Project 615 (Quebec) with the united engine, personified in the metal even in the middle of past century, it became unique in entire peace. But because of the frequent fires this submarine submariners themselves called it "cigarette lighter".
The project originators of "Saint Petersburg" guarantee, what safety of operation by their GEU - by an order is higher. Head developer of propulsive systems with EKHG - special design bureauof boiler construction. Drawing on experience of Ural electrochemical combine and NPO "energy"on the creation EKHG for the automatic spacecraft, SKB developed engine for the submarines "crystal -20", in which is used oxygen and hydrogen.
New submarine possesses tactical-technical elements, which, on the assertion of draftees, they will allow into two, and that three times to exceed on the combat effectiveness of thesubmarine of the third generation. New construction distinguishes the high degree of the automation ofthe processes of centralized control of all boat systems and weaponfrom the operator panels, located in primary command post. The power of rocket- torpedo complex is increased. "Saint Petersburg" they will arm with new antiship missile complex KLUB- S with the new automated information system for control ofweapon. New inertial navigation complex will be established. Hydroacoustic complex is also built on the new element base and withthe newest software. In the nose extremity highly sensitive hydrophone antenna is placed. Fundamentally new universal multifunctional periscope is established, not penetrating into the durable housing. Is inculcated the new system of the method of radio-information fromthe coast in the underwater position.
The level of underwater noise is reduced by more than 30 decibels, and the level of the radiated acoustic power - is more than into thousands of times! Thus, the noisiness of new boat will be practically approximating the background values of sea. Consequently, on the reticence it must exceed all submarines, built thus far not only, but also somewhere abroad.
