The advantage of the scheme Kilo 636 is a very low noise level, making the ship almost become "invisible" before the scout weapons acoustics (sonar) enemy.
New Year 2014, good news came with the Vietnam People's Navy: The Kilo improved scheme named first 636 Hanoi, number HQ-182 was about to Cam Ranh Bay. For the first time, Vietnam Navy have in hand a brigade of the most modern submarines in the world, willing to do the task of protecting the sovereignty of the islands of the country.
Kilo 's first Vietnam - Korea bearing number 182 .The advantage of the scheme Kilo 636 is a very low noise level , making the ship almost become " invisible " before the scout weapons acoustics ( sonar ) enemy . Therefore, the Kilo is the Western military expert nicknamed " Black Holes in the ocean " . So thanks Kilo Where can achieve the same degree of smoothness ?This ability may be , firstly by rounded hull design , rubber coated layer is thick , the sound absorption including infrasound and low-frequency eddies , while reducing drag. Rubber coated layer scheme Kilo Vietnam's 636 simulated leather texture dolphins , including laminated woven into each tooth comb . Outside the rubber layer billion cubic light to reduce sonar signal reflections , inner rubber layer is the larger mass ratio to absorb sound .
636 Kilo dubbed " black hole in the ocean ."The second is due to the engine . The removal of low frequency infrasound submarine very difficult , but the sound down so far this transmission , and to expose the submarine position . Scheme Kilo 636 diesel and used generators , so it should be possible to completely shutdown , the sea lying in ambush enemy , minimizing the infrasound emitted . Improved Kilo not use actuators with gear noise , which co- designed motor with propeller shaft speed ; the engine applies new techniques to minimize noise .Third, to limit the whirlpool, improved Kilo 7 wing propeller uses large diameter , cupped the fish effigy . Front propeller concentric grooves are sawn , minimizing water swirling .Thanks to the three specifications , Kilo 636 scheme has very low noise level . For comparison , we can provide the representative submarine attack America's most modern Virginia .
Although very modern , but American submarines Virginia " noisy " than Kilo so many times .Virginia Submarine water displacement of 7,800 tons , twice the amount of water relaxation Kilo is 3950 tons ( submerged ) submarine Virginia but using nuclear reactors with a capacity of up to 30MW , more than 7.5 times the capacity of 4MW Kilo . When running the same speed 20 knots / h , Virginia submarine used 6 times capacity improvement Kilo . Therefore, revealing the level of infrasound , whirlpool and 6 times higher , serious threat to the ship's secrets .In addition, the improved Kilo class submarines can dive up to 300m deep infrasound to reduce reflections , while Virginia submarine can dive 240m deep .When you turn off the engine , Kilo totally quiet , which can lie dormant in the sea ambush the enemy without being detected , while Virginia submarines in any given moment to run nuclear reactors staff , large noise . In turn , improved Kilo class submarines will have periodically surfaced for air , and to expose the ship location . However, this is not so important , because Vietnam used 636 submarines scheme for sovereign duty to protect islands , submarine operations not too far from shore .It can be said , in the hands of the Vietnam People's Navy , 636 Kilo scheme is a weapon , a " black hole " in the sea causing terror to the enemy . Kilo submarines with surface ships and shore missiles will be three main sets of the Vietnam People's Navy in the protection of national sovereignty over islands .
