.    Chapter 578 Super Submarine

In September, the South has already entered the summer season. The weather in the south has clearly felt the power of summer heat, and in the north, it has just felt the heat of early summer.

Liugong Island, a small island located outside the Shandong Peninsula, has become an important base for Chinese naval construction and stationing due to its unique geographical location. Even half of the island was marked out to become a memorial tourist destination for the Qing Dynasty fleet in the Sino-Japanese War of 1894-1895.

But the other half of the island is tightly separated from the open area with barbed wire, forming an important naval base shared by the Yellow Sea Fleet and the East Sea Fleet.

On the dock, there were about a dozen ships of all sizes that had just finished their patrol missions and were resting on the dock. The sailors who were not on duty were prepared to go to the public open area on the island to eat, drink and relax.

As Japan turned completely to the United States, the East China Sea and Yellow Sea fleets suddenly changed from facing Japan's semi-destroyed navy to facing the strong U.S. Navy at sea. The vacation that could have left the Liugong Island Naval Base and went to the land for a few days was cancelled. All the docking sailors could only rest on the island to deal with the powerful U.S. Navy.

However, many people don’t know that on that night, a conventionally advanced submarine quietly sailed out of the submarine special dock in the Liugong Island Naval Base under the cover of night.

The submarine special dock that has been covered by thick camouflage nets makes it impossible to get a glimpse of the content. Even the special guard soldiers on duty on the dock stopped the curious people who were intending to come over to explore the secrets.

Because if the sailors see this conventionally powered ocean-going attack submarine, they will find that this advanced ocean-going attack submarine is not the kind of traditional submarine they can often use, but has a high ridge on its back that is as protruding as a camel hump.

After entering the diving area, the submarine quickly dived, sneaking through the Bohai Sea to a mysterious island. Here, even if the submarines with only two nations were unable to enter the island, they could only float up and dock far away a few nautical miles outside the island.

After a small fleet of special speedboats and destroyers arrive, we must put down our lifeboats and send a new group of crew members to the submarine, and then pick up and send a group of crew members on the submarine back to the destroyer.

Peng Tao stretched his waist tightly and stood on the deck of the destroyer smoking hard, stretching his sore bones hard, "Oh, I haven't been on the boat for a while to control the wheel rudders and mechanical valves, and when I first returned, I was really uncomfortable."

Shen Tao took the cigarette handed over by the first mate and lit it easily with a cool fire lighter in the sea breeze. While enjoying the smoke of the cigarette and the air with the smell of the sea, he and many seamen like to let his lungs enjoy such double pleasure in his spare time.

"Yes, I've been learning this theory and I've been vomiting when I see the book. I have dense calculation formulas and a lot of conventional theory learning. I didn't expect that I've driven a conventional submarine for a lifetime, from an ordinary submarine of a trainee sailor to an improved Q-type submarine that I had played badly. As a result, I still have to study again with the new sailors. If I knew that such a nuclear-powered submarine could not even be as relaxed as a conventional submarine before, I would rather work the conventional submarine again."

The first mate complained a little unhappy, originally thinking that nuclear-powered submarines were not much different from conventional submarines. It was not until Huludao that everyone knew that although nuclear submarines had the same submarine functions as conventional-powered submarines, the various subjects extended from their core power sources, from the size and their nuclear power were several times more numerous than conventional-powered submarines.

"I sound a little against my will. How can I remember someone who knew his mission and cried and shouted to become a member of the world's first nuclear-powered ship."

Chen Tao ruthlessly exposed the "bad behavior" of the first mate's disagreement. The first mate, whose real thoughts were exposed, laughed, but he didn't smile like this, but pointed at the book in Gonglang's pocket with his finger.

The title of the book is "Nuclear Powered Submarine Operation Manual". It seems that Gongro is now forced to take this thing with him so he can take it out to read and learn. Everyone's mind is the same, and they are working hard to become the first sailor of nuclear submarines in the world.

Both the first mate and Shen Tao belong to the submarine commander. When commanding the original Q-type third-generation submarine No. 098, they advance, retreat, and turn, and use the difference in mutual thrust between two propellers, one forward and one reverse. The two people can even reduce the 2,000-ton qiii submarine by more than ten meters less than the minimum turn-around radius required by textbooks.

Don't just open the gap of more than ten meters. Many submarine commanders have just reached an eighty-tenth level greater than the minimum turn radius of more than ten meters. It can be seen that the two of them have been immersed in submarines for their whole lives to control the submarine as skillfully as their own bodies.

However, after learning about nuclear power submarines, I realized that although the reverse power output of nuclear power can be achieved, this can also be done with the steam turbine blades, unit and bearings, which strictly limit the reversing time. At the same time, the full speed reversing is strictly controlled to the point where it cannot be used in non-emergency situations.

If the auxiliary motor on the submarine is used for power and the additional auxiliary propulsion device of the hull is used for reverse rotation, the reverse speed is not refreshing.

What’s more important is that the nuclear-powered submarine is huge and much larger than conventional-powered submarines. The rudder efficiency is extremely low when sailing slowly. It is difficult to adjust the direction of the nuclear submarine with a rudder at this time. Moreover, the lift of the submarine is reduced, and it is difficult to maintain a fixed depth control, which is easy to cause dangerous trim. Reversing requires great caution.

In addition, due to its own volume characteristics, nuclear submarines have great knowledge of propellers alone. There was no rule in the number of pulp blades in the previous submarines, most of which were five-blade high-speed propellers, because their performance was the most average and the best high-speed.

With the development and innovation of global military technology and the improvement of enemy sonar performance, the silence effect of submarines is becoming more and more important, because high-speed propellers will cause cavitation in seawater, causing great noise.

So the speed is reduced, but the speed is reduced. The speed of the submarine is also reduced. Because the diameter is the same, the speed is the same, and the angle is the same, the larger the wet area of ​​the blade, the more sufficient thrust it has, so the area of ​​the blade is necessary to increase the area. The easiest way to increase the area is to increase the number of blades and increase the diameter of the propeller.

In the end, the propellers used on nuclear submarines were different from the seven-blade large-tilt low-speed propellers of the submarines before.

In addition to these, there are many special scientific theoretical knowledge that Chen Tao and others need to learn and master it bit by bit. Just one nuclear power working principle is enough to make Gonglang dizzy, not to mention other crew members and sailors.

The slogan proposed by Hualian’s Ministry of Defense is the establishment of an army in science and technology, and it is not enough to equip high-tech weapons. It also needs to cultivate commanders who can control these high-tech weapons and soldiers who fully exert their performance.

If we want to achieve this step, there is not enough basic education to cultivate a large number of young people with basic scientific knowledge and cultural level. These high-tech weapons can only lie quietly in the garbage dump like scrap iron and garbage to become decorations and waste products.

"How are those new sailors from the nuclear power group doing the drill?"

The first mate suddenly asked about his new membership in the future, which was another group added to the original submarine composition organization: the nuclear power control team.

The members of this team, regardless of the work of other cabins, are only responsible for monitoring and managing the terrifying and infinitely charming nuclear reactor at any time.

"It's okay. I asked them to go to the patrol boat to get bumpy and bumpy so that they can adapt to the bumpy environment on the sea. Although the submarines spend more smoothly under the sea, a sailor can't be seasick. No matter how awesome they are in their education and we are, first of all, they should still be a qualified sailor!"

Chen Tao pointed to the patrol boat that was flying around the sea not far away. The patrol boat kept slamming the sea, and the bumps and undulations made some people firmly grasp the handrail next to the patrol boat. The sharp-eyed first mate could even see these people vomiting into the sea today's lunch.

"Oh, it's really hard to make for these college students. I was exhausted by being trained in a marching queue on land. I was tossed and killed by folding those tofu pieces under the sea every day. After floating up, I had to be trained on the sea surface." The first mate shook his head, trying not to see these new sailors who were experiencing seasickness and physical adaptation.

If these members of the nuclear power equipment are just scared, many people will be scared. All members have a junior college degree in nuclear physics application in a group of advanced higher education colleges in China, including South China University, which is equivalent to Shen Tao and the first mate.

The two positive and negative team leaders have bachelor's degree and more than three years of practical experience. In terms of education, these prides from the ivory tower are enough to make Chen Tao and others feel proud while feeling deeply stressed.

To recruit such high-education personnel, we have to mention the nuclear physics application major that was opened ten years ago. Unlike nuclear physics theory research, these nuclear physics application majors are not as good as those of senior scientific researchers, but they are considered professional expertise.

What they learned was how to manipulate these enriched uranium with terrible energy, and under manual control, release controllable energy little by little in a special reaction chamber. All of this, without sufficient basic education and popularization, it is impossible to recruit talents so easily now.

"I said, don't relax basic training because the other party is a college student. Although the living conditions on nuclear submarines are n times better than those on conventional submarines, the more advanced the weapon, the more attention they need. They have the life and death of the entire ship."

"If they are the kind of people who are arrogant and arrogant, I will be the first to apply to Commander Xu to replace them. Because the greater the ability, the greater the responsibility! Good guy, the guy they control is an atomic bomb!"

He bounced the cigarette butt in his hand hard into the sea. Chen Tao looked at the new sailors who kept making the patrol boats tilted around, his face was quite serious.

Seeing that Chen Tao had already spoken, the first mate couldn't say anything else. After all, the other party was the captain. In this special large family group on the ship, the captain's words were like the parents' words, which was unquestionable and contrary to the words of the captain.

Perhaps Chen Tao's harsh requirements are a bit nitpicky, but only the officers and soldiers who have lived and worked on the No. 098 submarine know that it is precisely because of Chen Tao's harsh requirements on weekday training that every sailor can perform the greatest effectiveness in working and fighting.

Just as Chen Tao and his team returned from the submarine to continue their next subject training, in the nuclear submarine base on Huludao, the huge factory was transferring submarine modules produced in segments from outside.

In the base assembly room responsible for several core cabin sections, a huge rolling mill is rolling a whole piece of thick and hard special steel plate at a specified arc at a constant speed. Staff members are checking whether the speed and arc of the steel plate outlet meet the requirements at any time.

After the preliminary arc-surface rolling is completed, these steel plates will be lifted by the factory crane to its next assembly area to weld. Here, there are more than 100 special welders drawn from shipyards and factories across the country. These special welders will use their amazing working skills to complete the welding work of various welding areas of nuclear submarines with quality and quantity.

Long-term industrial accumulation and education accumulation have once again exerted its power. It is not very difficult to draw more than 100 special welders from the country at this time, but it was still very difficult to complete such a talent gathering more than ten years ago.

After welding and assembling the inner layer of these nuclear submarines, it is not basically completed. Many inspections are required in the nuclear submarine, and the acceptance review is extremely harsh.

Even though everyone believes that these welders and assemblers at the highest level in the country are at their superb level, the most demanding acceptance standard is not to pick the bones in the eggs, but to ensure the safety of the nuclear submarine after being launched with a serious and responsible attitude.

Here, there are even the latest radioactive equipment for hull flaw detection. Using a small industrial enriched uranium block like a key chain as a radioactive emission source sounds terrifying, but the strong penetration of uranium radiation can just see cracks and scars inside the metal and the cavitation generated during welding through the thick metal.

Under the pressure of hundreds of meters of seabed, any small crack may put the entire submarine in a terrible disaster. The birth of this newer and more stringent equipment is not only a best example of the extension of China's nuclear physics, but also represents the beginning of China's industrial level being improved again.

In the nuclear submarine base on Huludao, in the huge closed workshop, four submarines that started construction at the same time were quietly lying, each with a displacement of more than 6,000 tons.

Compared with the advanced submarines, two have a drip flowing shape and more torpedo launch tubes. The sound silence tiles laid on the submarine bulkheads are the first things that Gonglang and others have heard of. The already quiet and terrible nuclear-powered submarines, coupled with such terrible sound silence equipment, are even more at will to sneak in and sneak attack.

In addition to these two are obviously attack nuclear submarines, the other two have high convex ridges like the advanced submarine with high convex ridges.

However, from the current production progress and its skeleton, we already know that these convex ridges were integrated designs that were considered at the beginning of the design. When we look at this special convex ridge submarine, many people will know that this is a strategic nuclear submarine in the future.

Unlike the ocean-class submarines that modified experimental submarine-launched ballistic missiles, the wider dual-row design of this strategic nuclear submarine that will be launched in the future not only fully utilizes the width of the submarine itself, but also greatly increases the number of submarines carrying submarines.

Judging from the number of launch tubes installed now, each strategic nuclear submarine will be loaded with twelve submarine-launched medium-range ballistic missiles. Of course, the size and size of this strategic nuclear submarine, which is still super confidential, is larger than that of an attack nuclear submarine, so that it can load so many strategic missiles in its lower abdomen.

Looking at the entire assembly area, the slogans on the walls remind the workers from time to time to carefully and meticulously complete each work. In addition, there is also a slogan that deeply inspires every worker and the sailors who come to help and learn on the spot among the helpers.

"Working hard for 100 days, we ensure that the nuclear submarine launch trial mission is completed on time and in quality!"

At this moment, an old worker came over and took off the activity number one zero, hung a zero in front and two nine-character characters behind.

Although it is less than a hundred days before the nuclear submarine is launched for trial sailing, it will take a series of trial sailings before this epoch-making scientific and technological product can be officially installed and put into use.

The reason is very simple. The nuclear reactor on the submarine alone made all senior military generals jump straight. At the same time, because the nuclear submarine can rely on its own power to circulate electrolytic oxygen, the nuclear powered submarine can theoretically stay underwater after sailing.

This design definitely improves the concealment and survival of nuclear submarines. Before the nuclear submarine is truly put into actual combat, relevant scientific research has gradually mastered the laws of the underwater departure time period of nuclear submarines.

Researchers have found that the time for submarines to patrol and train continuously in the ocean depends on the durability of submarine crew members.

In an experiment in Hainan that once scuba dived into the sea for more than 80 days, the experimenters noticed that because the submarine was like a stuffy can, it mostly cruised under the dark water.

The connection between man and nature is isolated, so that the people in this artificial jar cannot enjoy the sun's light, breathe the fresh air of nature, and hear the sound of nature.
