Upset! The 095 shaftless pump-jet propulsion has become a legend, and China's nuclear submarines have completely shaken off mockery! A major breakthrough in China's 095 attack nuclear submarine! Equipped with the world-leading shaftless pump-jet technology, its quiet performance is close to the US Virginia class!
Finally bid farewell to the label of "underwater tractor" that was mocked by foreign countries for half a century, becoming a "deep-sea black hole", which shocked all countries.
Who could have imagined that half a century ago, China's nuclear submarines were in an embarrassing situation of "having but not strong". On August 1, 1974, the first unit of China's first nuclear submarine, the 091 type, Changzheng No. 1, was commissioned, achieving China's "zero breakthrough" in nuclear submarines!
Breaking the technological blockade of Western countries, allowing China to join the ranks of nuclear submarine powers. However, due to the level of national defense industry at that time, the 091 type only solved the "existence" problem, and the most fatal weakness was its noise level of up to 160 decibels, comparable to a heavy truck underwater.
It should be noted that the noise of British, French, and Russian nuclear submarines is about 100 decibels, while the US Sea Wolf class and Virginia class are as low as 95 decibels, almost matching the background noise of the ocean.
The huge noise made the 091 type easily exposed, and it was mocked abroad as "sailing out from the port, it can be monitored in Japan". Noise is the "fatal weakness" of nuclear submarines, not only making them easy to be locked by enemy anti-submarine weapons, but also interfering with their own sonar systems, falling into a "passive beating" situation.
Now, the emergence of the 095 nuclear submarine has completely changed this situation. Thanks to the breakthrough in the electric propulsion field by Academician Ma Weimin, the 095 is equipped with the shaftless pump-jet technology, skipping the bottleneck of the shafted pump-jet and directly achieving world-leading standards.
This technology completely eliminates the shaft, integrating the motor inside the casing, similar to the hub motor of a chainless electric bicycle, completely eliminating shaft noise, and also avoiding entanglement of underwater foreign objects, suitable for complex sea areas.
Currently, although the nuclear submarines of the US, UK, France, and Russia have adopted pump-jet technology, they still mainly use the shafted type, and have not yet widely applied the shaftless pump-jet. The breakthrough of the 095;
Not only has it brought the quiet performance of China's nuclear submarines to the top level of the world, but it also demonstrates the rise of China's national defense industry. From "underwater tractor" to "oceanic black hole", after more than 50 years of seclusion, China's nuclear submarines have finally regained their dignity, becoming a "submerged blade" to safeguard the country's maritime rights and interests.
