Shen Huan continued: "Now I want to analyze the importance of developing AIP-powered submarines from the operational needs of my country's naval submarine force.
Since the water depth in China's eastern waters is not deep enough for submarines to conceal, China's submarine forces in the East China Sea need to go eastward into the sea area with a water depth of more than 2,000 meters before they can obtain a relatively good space for covert operations.
Of course, in order to break through the five or six hundred kilometers and the average depth of only a few dozen meters in the continental shelf of the East China Sea, it is necessary to maintain the state of underwater diving, but whether it is the Type 035 submarine we are equipped with now, or the Kilo class that we have introduced, including the new conventional submarine we launched today, the underwater cruising distance is only three or four hundred nautical miles, and this is a theoretical amount of underwater cruising distance, and in practical use, it is generally about half of the residual power to float up for charging.
Therefore, our submarine forces have always been tracked by the anti-submarine aircraft of the foot basin country when they leave the island chain, and this is because we cannot achieve complete submarine concealment in the continental shelf waters of the East China Sea. ” The naval chiefs listened attentively one by one, and they all recorded them in their notebooks from time to time.
Shen Huan paused and said: "Similarly, although the submarine force of the South China Sea Fleet can sail for a long time under the air cover of our naval aviation, after passing the Dongsha Islands, it is basically out of the cover range of our naval aviation, and there are also many P3C anti-submarine patrol planes, which makes it easy for my submarine force to be discovered and tracked by anti-submarine aircraft when they go out of the island chain."
Therefore, if we develop our own AIP-powered submarines, then it will greatly change the current situation, break the anti-submarine system built by the United States and the foot basin country, and allow our submarine forces to achieve covert access to the island chain. ” "Because fixed-wing anti-submarine patrol aircraft mainly rely on surface search equipment such as airborne radar and forward-looking infrared search sensors to improve their submarine search efficiency and range.
Therefore, when searching for submarines that do not need to be charged with snorkels, its efficiency will be greatly reduced, which is equivalent to losing its radar search capability.
Therefore, after China has AIP submarines, it will be able to break through the blockade circle in some relatively favorable sea areas and freely enter and exit the Pacific Ocean.
Because the surface ships of the United States and the Foot Basin countries have much weaker maneuverability than anti-submarine aircraft, it is impossible to achieve a comprehensive blockade.
Therefore, if we build our own AIP submarine force, then we can seize the weakness of the anti-submarine system built by the anti-submarine patrol organization of the United States and the basin country, and achieve effective strategic countermeasures. ” At this time, the head of the navy couldn't help but stroke his palm and smiled: "Comrade Shen Huan, your analysis just now is indeed very wonderful, and this is something that none of our naval strategic experts has done!"
It seems that our Jiangnan Changxing is indeed Crouching Tiger, Hidden Dragon, hehe, you continue!
” Shen Huan saw Feng Haibo and other leaders showing pride on their faces, which was tantamount to praising the entire Jiangnan Changxing Shipbuilding Group, and of course, praising the leaders of Jiangnan Changxing Shipbuilding Group as Bole.
Shen Huan's heart was very calm, because he knew that he could only throw bricks and lead the way, and to build China's own AIP submarine, it was not possible to rely on him to say a few words, because the technical content in it was too high, and foreign countries would definitely impose a technological blockade on China.
Shen Huan groaned: "To develop our own AIP power, I think we should start with the Stirling engine, I think this technology is relatively easy to implement."
Because the fuel of the Stirling engine is still diesel, and the oxidizer is liquid oxygen, its logistical replenishment is relatively simple.
As long as the oxidant can be effectively replenished, the underwater endurance of the submarine will also be greatly improved, just like the aerial refueling of fighters, if this AIP submarine provides some liquid oxygen supply on the way, its underwater continuous diving ability will also be greatly improved. ” At this time, Li Jie, the chief engineer of the submarine, also laughed and said: "Comrade Shen Huan, you have played this metaphor very well, our submarine can also be replenished in the water, which is indeed similar to refueling in the air."
And I think it should also be able to achieve partner replenishment between submarines and submarines in the same way as partner refueling.
Of course, I think that in addition to being able to dive underwater for a long time, the AIP submarine has a more important point, that is, it uses electric propulsion underwater, so its quietness is also very good, and it is easier to conceal due to its slower speed.
During the operation, the favorable hydrological environment such as the thermocline and the salt cline in different seasons can be used to covertly penetrate into the northeast sea area of T. ” Shen Huan nodded and said, "Yes, Chief Master Li Jie got to the point."
I also analyzed it, this section of the distance is only four or five hundred kilometers, if we have an AIP submarine, its underwater range should not be less than two thousand five hundred kilometers, this distance only accounts for one-fifth of its endurance.
Therefore, our AIP submarine will have more than ten days to continuously dive and conceal underwater for a long time.
In addition, in the Bass Strait between T and the Philippine Green Army, which is greatly affected by the monsoon climate and the complex topography of the seabed, it is very conducive to submarine activities, and it is also a strategic point for China's submarine force, so after having the AIP submarine, it can also make full use of its long-term underwater endurance and operate in the entire eastern and southern waters of T. ” At this time, the head of the navy couldn't help but laugh and said: "This is only to the south, if it is to the north, it should be equally promising."
If our AIP submarine breaks through to the East Sea of T, and then goes north, it can rely on its strong underwater endurance to reach the east side of the Ryukyu Islands island chain, and even reach the Amami Islands north, and on the way also include Naha, an important foot basin on the main island of Okinawa, and the Far East military base of the United States. ” "Of course, in the South China Sea, our AIP submarines are also promising!
In Malacca, a country with a waterway where antisubmarine warfare forces are to be arranged, the ability of AIP submarines to conduct covert submarine operations can completely raise the strike capability of China's submarine forces in the South China Sea to the level of strategic strikes!
That's great!
The chief looked very excited.
It's just that the words of Li Jie, the chief engineer of the submarine, made him calm down immediately.
"It's just that to develop our own AIP submarines, it's too technically difficult.
Foreign countries will definitely impose a strict technical blockade on us, and we can only rely on limited information to make Stirling engines by ourselves.
The Stirling engine is a closed-cycle piston heat engine, and its operating gas is always stored in the cylinder, so this is not easy to achieve.
For example, the reliability technical problems such as ultrafine crystallization, fretting wear, corrosion fatigue and other reliability technical problems of superalloy of key components of the engine, as well as the high-temperature sintering, uniform control of porosity and high-temperature sealing of key components of porous media, as well as how to solve the problems of cavitation, corrosion cracking, short life and high friction power consumption that often occur in Stirling engines.
As well as special welding, special material processing and other technological problems, are all in front of us, real obstacles.
Chief Master Li Jie sighed.
