Since the Yuan-class submarine appeared since its original appearance and outstanding performance to lead to military enthusiasts around the world and the concern of national military experts, is that U.S. intelligence unit on more than restless. As China's new Yuan-class conventional submarines level represents the current conventional submarines of the latest technology. Western experts said the unexpected with the speed, unexpected, unexpectedly ... ... Following this, a variety of Fun Da and to an endless stream.
One school of thought that the "meta" level should be the Russian "Kilo-class," the brother, evolved from the Kilo class. There are two main evidence:
First, the element displacement and the Kilo-class submarines, very basic, and has a slightly protruding Kilo-class K-beam, and processes more visible profile, Yuan-class submarines can be determined within the spatial structure of the Kilo-class and basically the same layout. Second, the command station to adjust the location and size. Original Song-class submarine's tower size is too large, underwater stealthed, the resistance on the following difference is too large, we must rely on the first Yang rudder to offset the torque will increase with the submarine submerged into resistance; and the new submarine The tower of sail very close ratio and Kilo-class, shows that the Chinese military has been a conscious designer to compensate for this defect. So, the Russian-made Kilo-class and the Song-class submarines each comprehensive technical expertise, performance must go further and can be called "super Song" submarines.
One school of opinion is also that element belonging to the Russian Amur-class submarines should be improved level. Russia's military is the initiator of such statements. Russian Navy Technical analysts generally believe that on the Yuan-class submarines in the design of reference to the Amur-class concept. No class outline design with a drop of water, and discard the original 039-type submarines, whales, and Kilo-class and the inherited shape of the Amur-class concise. Interpretation of the meta level by elevator and rudder position of the hull, Russian experts also believe that the meta level is equipped with a passive sonar systems, sonar systems, and drag. Moreover, through the "confirmed" the 039-watt and improved sound-absorbing rubber silencer submarine layer technology, Yuan-class submarines, and perhaps the overall use of more advanced technology rubber cover, so that underwater noise down to 100 dB below the noise level so Russian submarines have been considerable.
In fact, the Yuan class submarines sail with the previous comparison of the other submarines, not only a highly significant decrease, and the greatly improved appearance and navigability. This is also a drop-shaped sail, from the whole, more plump and stubby hull sail together, that is beautiful and resistance. Therefore, meta-level should have been serving our country in conventional submarines, airworthiness and seakeeping best submarines.
Weapons systems, the United Kingdom, "Jane's Defense Weekly" claims that, as early as 2000, the Russian innovators had issued the Statistics Office of the 3M-54 "club" submarine-launched missile technology to the Chinese, the missiles from surface ships or Kilo 877EKM / 636-type diesel-electric submarine launched, followed by the introduction of the Kilo-class submarines is to master the advanced submarine-launched missiles and torpedoes, the power of the huge "mass destruction technology", "no doubt" will be used in the meta-level submarines. In addition to Russian-made weapons, Yuan-class submarines equipped with certain will choose a new generation of Chinese self-developed naval equipment. Tokyo at the U.S. Naval Intelligence Officer John Mack in Asia, said China's recent deployment of Raul three yuan-class submarines with "long-range strike capability." They are equipped with C-802 anti-ship missile (from boat bow torpedo tube launch 4). Podium in his escape capsule with the first one export, but also on the deployment of submarine-launched cruise missile type 6 CSS1, the range in the 700-1200 km and, to a large aircraft carrier battle groups to combat, in addition to the missile also uses the Chinese their deep-sea cold launch technology.
Foreign experts are silent on the Yuan-class submarines performance suggested the most "daring." United States, "Washington Post" pointed out that China will definitely upgrade the submarine's propulsion system, such as the motor shaft speed of 500 rev / min to 250 r / min, while using double elastic cushion seat, cushion and other engine installation measures to significantly reduce the noise level in the submarine. Because China has a "buy technology, the introduction of technology is better than" traditional, when China bought from Russia 877EKM, 636 Kilo-class submarines after the type. Is bound to the submarine's propulsion system to digest and absorb. Through the use of these measures will enable the Yuan class submarines quiet the noise down to an astonishing level of 96 dB, almost equal to the "black hole" nickname of the Kilo-class submarines. At present only one view of the U.S. Navy active sonar can capture the reflection echo Kilo-class, so the per-class submarines great concern the noise index is expected.
Conventional submarine underwater in pursuit of maximum range, I do not know how much worry about evil genius of talented designers, and finally evolved relatively well AlP system. The meta-class submarines to China, the foreign public media is one voice, firm and unambiguous AlP that China already has the technology on the grounds that China's ally Pakistan has received from the French Agosta 90B submarines AIP technology, the AIP technology is known as the French MESMA (independent energy model submarine) steam turbine system to ethanol and liquid oxygen as the energy, drive a turbine generator. This technology can increase underwater endurance 3 to 5 times. By lengthening the hull section, can be easily fitted to many active-duty submarines.
Often spy submarine AIP system allows greatly improved ability to sail. But at the same issue also comes into the department. As underwater for long periods, can not use celestial navigation for position correction, it is easy positioning device by the accumulation of gyro error. However, on three Chinese engineers in South Korea in 1999, the international gold medal of the paper "Current database on information fusion method of underwater navigation", China is likely to have been resolved, the precision of underwater navigation problem. Authors on underwater navigation information fusion algorithm to compare creatively put forward the currents through the establishment of comprehensive databases, in order to increase the accuracy of the navigation information from the high, reference sources, and made applicable to information fusion algorithm for underwater navigation . Through a large number of computer simulation experiments and sea trial proved that the method can greatly improve the precision of underwater navigation, and highly practical.
No class submarine electronic system also has been great concern in the United States, the U.S. military that the element level is quite advanced sonar system, installed in the boat has a bow in the frequency passive sonar search and assault case. And a set located at the side of the passive low-frequency sonar array search, will be equipped with domestic passive sonar towed array systems.
In fact, meta-level of basic use of electronic systems is a new song to change <039A>, there are boat hull IF the first active and passive attack sonar, side low-frequency passive listening sonar array, improved from France DUUX- towed array sonar listening type 5 <093 was used for remote French anti-submarine prototype>. The sonar has been changed in the new trial Song mature technology, improved and placed in the meta level is no technical risk. Yuan-class brand-name master computer is a domestic military rugged, fast operation, which can handle various types of data coming from various sub-systems information and command instructions issued by the correct and timely. Has achieved digital command, control, weapons management system, information on boat times and data link system composed of boats on the C4I system. Optronic Mast is the new CCD does not penetrate the hull of a body, a detection radar using imported since the introduction of improved, focusing on the installation of the boat in China developed a submarine underwater Professor precise navigation and positioning system <093,094 nuclear submarines have EQUIPMENT ". The high precision navigation and positioning system, is the world's most advanced, can greatly improve the accuracy of underwater missile attacks.
