Complete information and Analysis on "Sindhu" class Submarine

[sherkhan]

Most diesel-electric submarine (type "B"). Development of the project started on the tactical and technical assignment approved by the Soviet Navy in 1974. Design was conducted CDB "Ruby" (CDB-18) together with the Research Institute. Academician Krylov, the chief designer of the project - Yu.N.Kormilitsyn. Technical project approved by boat commander in chief of the Navy of the USSR December 20, 1976 Pre-production project at the head of the boat Shipyard №199 "They. Lenin Komsomol" (Komsomolsk-on-Amur) started in 1979. Bookmark the head of the boat B-248 held March 16, 1980 The boat launched on September 12, 1980 and commissioned to the Navy of the USSR December 31, 1980

In 1981, after the discovery of a new type of submarines in the NATO boat he was given the nickname KILO. According to unconfirmed reports headache pr.877 boat B-248 went into service in September 1982 is possible at this time to achieve a complete test head naval submarine. Serial production of boats pr.877 lasted from 1979 to 1994. Total built at different factories:


- Factory №199 "They. Lenin Komsomol" (Komsomolsk-on-Amur) - from 1979 to 1994 built 15 boats;
- the plant "Red Sormovo" (g.Gorky - Nizhny Novgorod) - from 1982 to 1995 built 17 boats including and for export;


- Plant Leningrad Admiralty Association (Leningrad) - 1983 and 1991 7 boats built for export;
- FSUE "Admiralty Shipyards" (St. Petersburg) - 1992 to 2000 4 boats built for export and from 1997 to 1998 2 pr.636 boats, and from 2002 to 2006- 5 boats pr.636M. One boat pr.877 completed in 2005 pr.636M (B-340 = Yuan Zhend 73 Hao, China). Some time ago (1997) in the Western media of specialized boats KILO class as referred GRANAY, probably referring to the boats upgrade projects 636. By default, these boats are pr.877. In 2010 FSUE "Admiralty Shipyards" (Mr. .Sankt Petersburg) resumed the construction of submarines for the Russian Navy pr.06363 ( sm.Reestr below ) - in the construction of a series of six submarines for the Black Sea Fleet of the Russian Navy.

Design PL - double-hulled. Widely used damping platform and other sound-absorbing technology (eg protivogidroakusticheskoe cover housing). The shape of the body is adapted to the PL maximum resistance and noise reduction. Nasal hydroplanes retracted into the housing. Submarine pr.877M differ in appearance from pr.877 chopped off at the stern superstructure instead of blending smoothly into the body. Material hull - Steel AK-25. At least for PL pr.06363 steel cabinet designed "Prometey" and performed at "Izhora Works".

Propulsion : the underwater and surface course of submarine propulsion motors is provided
2 x diesel generators 4DL-42MH capacity of 1500 kW (at dr.dannym and the first two submarines pr.877 - 4DL-42M power of 1000 kW) with a system of RDP (pr.877). On pr.877M - 30DG capacity of 1500 kW, as well works with RDP.

1 x main propulsion motor power of 5500 hp PG141 (Including pr.877V / 877EKM at dr.dannym on pr.877EKM engine produces 4050 horsepower), since the submarine B-800 (1989) set a new low speed engine capacity of 5500 hp PG165 . (6800 hp by Western sources).

1 x motor of economic progress PG142 power 130-150 hp (The first version), since the submarine B-800 (1989) / pr.877V set a new low speed engine output of 190 hp PG166 ..

2 x redundant motor PG168 (apparently, since the B-800?) With a capacity of 102 hp

Mechanics - one shaft, one screw:
- 6-bladed fixed pitch propeller low noise (B-470? and B-800)
- 7-blade scimitar-shaped blades with alloy "Aurora" (B-470 - 1986 B-800 - 1989).
- 7-blade propeller-type B-800 (Improved KILO Submarine).
- water-jet nozzle turbine type (pr.877V previously was shorter tip - perhaps the difference early on pr.877V pr.877VD - is supposedly).
The speed of rotation of the screw top - 250 rev / min .. On submarines all projects in the stern of the hull on the sides thrusters water cannon.Processes diving and surfacing submarine automated.

Noise submarine pr.877 when driving on an auxiliary propulsion ustanovlke (water cannon) at the rate of progress of low noise (MSHH) 5-6 bonds is estimated by experts below or equal to the noise class submarines Improved Los-Angeles. When using the progress under the main propulsion motor noise performance is particularly limited regardless of the speed. Based on reviews of Indian sailors on submarines pr.877EKM total noise is considered quieter German submarine pr.209. In the natural background in the 40-45 dB noise submarines calm pr.877 was 52-56 dB (SP series and measuring conditions are not known). The Chinese media reported on submarines pr.636 noise level 117 dB.

The project is based on a special submarine pr.877 - in 2002 on the advertising leaflet CDB "Ruby" is a side cutting projections on the basis of a special submarine pr.877 probably designed to work on laying pipelines on the seabed. Perhaps after such equipment can be used for submarine wide range of activities on the seabed. There is also a likelihood that these technologies and components have already been tested on other types of submarines. No other data. pr.06361 - Improved KILO - modification of the submarine pr.636M or another name for the project pr.636M submarines.
