Chapter 747095 Start of Construction

“Comrades, thank you for your hard work!” Wu Shengli’s voice sounded.

 “Serve the people!” the sailors shouted.

Among all arms, submariners are a special existence. They live in a silent underwater world and face various emergencies at any time. They are under tremendous pressure, especially those who participate in submarine test missions. The pressure on officers and soldiers is even greater. If there are design flaws or production flaws, they may be buried in the sea at any time.

 But they don’t care, for the sake of the strength of the motherland, they are willing to take all kinds of risks!

 Now that they have finally completed all the test tasks, they submariners will also become the first batch of official officers and soldiers of the 093 submarine. They are still very proud to operate this underwater dragon.

 Now, facing the review by naval leaders, they are even more energetic and radiant.

Kvasa stood aside, also looking at the submarine.

The construction of the 095 submarine is about to begin. The only 093 submarine is also an eye-opener for him. He wants to see the construction level of his brother units.

From his point of view, 093 is still good. At least during the test, the silencer tiles did not fall off. However, the appearance of the submarine is outdated, especially the submarine's control tower, which still uses an old design.

"Now, on behalf of the Navy, I announce that the 093 nuclear submarine has officially passed the sea test, joined the People's Navy, and has since become one of our important underwater weapons!" Wu Shengli continued to deliver a speech for about ten minutes, and the nuclear submarine finally It landed firmly on the berth.

"Now, let's go up and have a look." Mr. Peng couldn't wait.

 Kwasha followed.

The sailors were a little curious when they saw that Lao Maozi was also at the scene. However, they all knew that there were a large number of Lao Maozi experts in the country. Since the Lao Maozi in front of them was qualified to come here, he was naturally qualified to go up and observe.

“The air inside is pretty good. It seems that our new purification device is working well.” After going up, Mr. Peng was first impressed by the freshness of the air inside.

 When a submarine sails underwater for a long time, it must have enough fresh air, especially enough oxygen. Otherwise, all members of the submarine may be killed.

Therefore, all kinds of submarines will always have oxygen regeneration tablets and oxygen bottles. However, these are used in critical situations. Under normal circumstances, nuclear submarines will use electrolysis of water to produce oxygen, while conventional submarines use snorkels. .

 In addition to oxygen, there are other gases in the air, such as carbon dioxide exhaled by people, such as hydrogen and carbon monoxide, etc. If these are not eliminated, they will still pose a threat, and they are usually achieved through special air purification devices.

Even so, after the submarine returns from the sea, the smell inside will be quite unpleasant.

Now, this nuclear submarine has always been in a submersible state, and only floated inside the cave. The internal air quality is maintained well. This is of course due to the effect of the brand-new air purification device. This thing does not look very eye-catching, but it is very effective. The air quality plays a very good filtering role, which can improve the living comfort of submariners and enable them to work better.

"Yes, this air purification device is very good." said the submarine captain who participated in the test: "After a month underwater, the air quality can still be maintained similar to that outside. No matter how long it takes, we will have the opportunity in the future Test again.”

“How is the side sonar array going?” asked Kvasa, who could already speak fluent Oriental.

Facing this old man's question, the captain still had some doubts. Mr. Peng said: "This is the designer of the next generation submarine. The side sonar array used on your submarine was originally assembled for the next generation submarine. "

 Designer of the next generation of submarines? The captain was immediately in awe: "Report, the side sonar array is so powerful! In our tests, we can detect the noise emitted by surface ships hundreds of nautical miles away, and it can also have good accuracy, and can even detect Our anti-ship missiles are capable of shooting Zhuyuan, but it is a pity that the range of the anti-ship missiles we carry is not far enough."

With their torpedo tubes, they can only launch YJ-83 anti-ship missiles at most, with a range of less than 200 kilometers. To attack potential target surface fleets, they need a range of at least 500 kilometers.

“The problem of anti-ship missiles will be solved by our next generation of submarines.” Kvasa said: “The performance of the side sonar array has reached the standard, and we will be confident in our subsequent research and development.”

“The performance is definitely up to standard, and it is also equipped with a sound-generating device that can simulate the sound of the 091 submarine. This idea is really good.” The captain said with emotion.

The West has always believed that Eastern submarines have poor performance and are underwater tractors. Therefore, they pretend to be tractors for them to see. When the time comes for real underwater confrontation, they suddenly reduce the noise to completely dumbfound the potential enemies.

"How is the noise of our 093? Is it up to standard?" Qin Tao, who was following behind, spoke.

"The noise is at least 20 decibels lower than our 091." The captain said: "It is quieter, but it is still incomparable to the noise of our domestic conventional diesel-electric submarines."

The first generation 091 was very noisy. The noise of the 093 has been reduced, but it is not particularly good. After all, the noise of nuclear submarines mainly comes from the nuclear reactor, and its reactor still uses an improved version of the 091.

 The quietness will not improve much. A reduction of 20 decibels is already great.

Qin Tao nodded. This is the significance of the 095 submarine. The noise can be reduced by another 20 decibels, reaching a level more advanced than the mainstream in the West. Especially since our own nuclear reactor has self-circulation capability. Without turning on the main circulation pump at low speed, the noise can be reduced to The level of oceanic black holes. At the Dalieshan nuclear power plant, this low-speed self-circulation capability has been verified extensively, and there is no problem at all.

The biggest advantage of 095 is the nuclear reactor. Compared with the 091 nuclear reactor, the power is much greater and the quietness is also improved.

“Let’s go to the back and have a look.” Krasnopolski also came up. What he was most concerned about was the nuclear reactor.

 A few hours later, everyone got off the 093 nuclear submarine. They were positive about this submarine, but also had many shortcomings.

"The technology of this submarine is still relatively mature. Although it uses a lot of advanced electronic technology to greatly improve its combat capabilities, its nuclear power system and so on are still improved from the 091, and its reliability Not bad, but it has not yet reached the first-class level." As Lao Maozi's famous submarine designer, Kvasa's evaluation is very fair: "After the verification of this submarine, the construction of our 095 submarine will be smoother."

“Yes, the further improvement of our underwater technology depends on the emergence of the 095 nuclear submarine.” Wu Shengli sighed: “This submarine will reach the level of the Sea Wolf class and keep pace with the world.”

The Navy no longer looks down on the 093 nuclear submarine, and everyone's attention is focused on the 095 submarine.

 This world-class nuclear submarine is finally going to start construction!

In fact, construction should have started long ago. However, the Navy has been short of funds in recent years. The Aegis warship will cost a lot of money, not to mention the 002 aircraft carrier project. Therefore, the only way to have funds is to complete the 093 submarine and put it into service. Support project 095.

On the way to Mingzhou Group, Kvasa introduced the 095 submarine project to everyone again.

"After repeated studies, we finally set the submarine at 115 meters in length, 12 meters in width, 11 meters in draft, and 7,900 tons of underwater displacement. This way, driven by our 150-megawatt nuclear reactor, we can achieve the maximum underwater The speed is 32 knots." Kvasa said: "Without turning on the circulating water pump, it can have a maximum silent speed of 20 knots."

The maximum speed is only a theoretical value. Few submarine captains dare to reach the maximum speed underwater when commanding. In this case, any submarine will become an underwater tractor and completely lose its concealment. For submarines For one, losing concealment means death.

 So, the maximum speed is not the goal to pursue. 30 knots is already very high. The domestic 091 and 093 can only run to about 25 knots and still ride underwater.

Although nuclear submarines need to provide underwater **** for aircraft carrier formations, in addition to taking off and landing carrier-based aircraft, aircraft carrier formations rarely reach 30 knots, which consumes too much fuel.

“The displacement of this attack nuclear submarine has reached the displacement of our 092 ballistic missile nuclear submarine.” Wu Shengli said: “Our navy’s equipment is also gradually developing towards large-scale.”

“This nuclear submarine also adds a special compartment for the 850mm vertical launcher. It is also possible to classify it as a ballistic missile nuclear submarine.” Qin Tao said.

During the design, Qin Tao proposed to add such a cabin. No one understood it at the time. Now, with the continuous implementation of the anti-ship ballistic missile project, everyone can finally understand that the vertical missile has a diameter of 850 mm and a length of nine meters. It is specially prepared for anti-ship ballistic missiles. This thing is a big killer against aircraft carriers.

 What is the mission of attacking a nuclear submarine? In addition to the enemy's submarines, there are also the enemy's surface aircraft carrier formations. In the future, whether on the surface or underwater, our own side will have powerful attack capabilities to make the enemy frightened.

"Our 093 can reduce it to 110 decibels, which is already very good, but for our 095, the goal is to reduce it to about 90 decibels. We will use pump-jet propellers to drive the submarine forward. At the same time, the entire ship's integrated power system , and motor-driven pumps are our basic equipment, and now these technologies are mature."

Kvasa is a submarine designer, but he is not omnipotent. His performance requires the cooperation of various departments. He is now very satisfied. In the East, all necessary conditions are met.

If it were in the Soviet Union, there would be no comprehensive power system to even think about. The weakest part of Lao Maozi is the electronic system.

"Currently, the highest strength steel produced by the Mingzhou Steel Plant is 1,200 MPa. We plan to use this steel for the pressure-resistant shell of the submarine, which will allow our submarine to have a diving depth of 600 meters. Kvasa said: "If you encounter special circumstances, you should be able to withstand it even if you dive to a depth of one thousand meters."

The deck steel currently used is already one thousand megapascals. The pressure hull used on nuclear submarines must of course be of higher quality. Of course, it must not only have high enough strength, but also must be easy to process and weld. At the same time, it must be easy to process and weld. , the price should not be too expensive, otherwise it cannot be used.

 Across the world, the number of companies that can produce nuclear submarine steel of this level can be counted on one hand, which fully illustrates how difficult the technology is.

Even if Mingzhou Group does not participate in the construction of nuclear submarines, just selling steel can play a great role in promoting the nuclear submarine industry.

At this time, when Kvasa said this, everyone present was shocked. In the past, nuclear submarines could dive to three hundred meters, but now, the depth has doubled!

“When we go to Mingzhou Group to participate in the groundbreaking ceremony of the nuclear submarine, we must see how the steel is processed.” Wu Shengli said.

“Everyone, there is still a problem that needs to be solved in the current construction of this nuclear submarine.” Kvasa said: “That is where the reactor of this nuclear submarine should be assembled.”

 At that time, in order to develop the nuclear industry, the country established a large number of nuclear industrial plants, the more famous of which was Plant 272, which was responsible for the arduous task of refining uranium dioxide from uranium ore and uranium concentrate. Plant 202 is responsible for uranium chemical conversion, uranium metallurgical processing, and nuclear fuel element manufacturing, in other words, making raw materials for nuclear reactors. Plant 504 is responsible for enriching uranium.

Plant 404, built in 58 years, is a comprehensive scientific research and production base for the nuclear industry standing on the northwest Gobi Desert. It has created "ten firsts in the nuclear industry" including the first reactor and the first nuclear material production line. In other words, normal nuclear reactor assembly takes place in Factory 404.

 However, Factory 404 is too old after all. Is it suitable for assembling such an advanced nuclear reactor?

“Where was the Mingzhou Group nuclear power plant assembled?” Wu Shengli asked.

"It is assembled on-site in Dalieshan." Qin Tao said: "I think Dalieshan can be used as our nuclear reactor assembly base. We are not afraid of others talking about nuclear discoloration. Including nuclear reactors of floating nuclear power plants at sea. It’s assembled there.”

For the people of Mingzhou, they have long been used to it. When the nuclear submarine was dragged from Lao Maozi and converted into a floating nuclear power plant at the Mingzhou Group, no one dared to object. After all, what the Mingzhou Group did was , but for the entire Mingzhou, and even the entire China.

Now, Dalieshan is completely under the control of Mingzhou Group, and the open space in Dalieshan has long been capable of assembling nuclear reactors.

“This needs to be reported to superiors, and experts from all fields can make a decision after joint research.” Wu Shengli said.

This matter is of great importance and cannot be decided by him alone. It must be done in accordance with scientific laws. Although generally speaking, the suggestions given by the son-in-law are correct, but he also has to follow some objective rules.

 Qin Tao nodded.

A few days later.

The busyness of Mingzhou Shipyard has become a habit. Even foreigners who come here will be infected by the enthusiasm of work here. The concept of working days and rest days has long been gone. For them, every day follows the daily routine. Going to work and getting off work at fixed times has become a part of life. However, they have no complaints about overtime work and overtime pay. Their normal work is already three times the salary of similar workers outside. What else is there to complain about? satisfied.

 Generally, the groundbreaking ceremony of a new ship will be very lively and everyone in the factory knows about it. However, the groundbreaking ceremony of a nuclear submarine is quiet.

 The entire submarine construction workshop is located in a corner of the shipyard and is very secluded. Since it is all built indoors, as long as the workers responsible for the shipbuilding task do not talk nonsense, the outside world will not know what is being built here.

As submarine export tasks gradually increase, the submarine construction workshop here is also constantly expanding. A newly built workshop is two hundred meters long and forty meters high. The entire submarine construction workshop is so wide that it is very impressive. Feeling.

"If our original nuclear submarine production plant wants to continue to produce modern submarines, it will also need to build new factories and workshops, which will cost a huge amount of money. Now, it is handed over to the Mingzhou Group to build, and these preparations will be completed by them. It is the most A good choice." A naval leader said with emotion.

  If the original production plant had to pay for these renovation costs, the navy would have to pay for it. Now it is the Mingzhou Group that pays for it, which is of course the best.

“However, this factory is really big. I guess it can even produce large submarines like the Typhoon class, right?” Another leader said.

"Our factory is designed according to the size of our ballistic missile nuclear submarines in the future." Qin Tao said: "After our 095 is launched, the construction of 096 or 094 should be put on the agenda. According to our largest With a diameter of 13.5 meters, the nuclear submarine can remove its turtle back and put all the Julang-2 missiles inside our hull, but the size of the submarine will also increase."

In the past, I have introduced the size of this kind of submarine to the Navy. The length is expected to reach 170 meters, and the underwater displacement will exceed 20,000 tons. A large submarine of this level must have a large enough factory to build it.

“Well, the length and height are enough, and the width is not small. It seems that two nuclear submarines can be built at the same time.” Wu Shengli said.

"That's right. Whenever the navy needs it in the future, we will build two ships together." Qin Tao nodded and looked towards the innermost part of the huge production workshop, where banners had already been hung.

 Warmly celebrate the start of construction of the 095 nuclear submarine!

After waiting for so long, the 095 nuclear submarine is finally going to start construction. Compared with previous nuclear submarines, its performance has been greatly improved, even a qualitative leap!

“Leader Wu, please give us a speech.” Qin Tao said.

Wu Shengli walked up to the rostrum in front and began to speak to the people gathered below.

 Part is the navy, part is the engineer, and part is the worker who specializes in building submarines.

"Comrades, I am very happy to stand here today. The 095 nuclear submarine is a submarine that has reached the highest level in the world. At the time of the 091 submarine, we only solved the problem of having or not having it, and the performance was low. By the 093, the performance began to improve a lot. A big improvement, but what really makes us satisfied is this 095. Our underwater power will be on par with the world, or even higher!"

"Over the years, Mingzhou Group has been developing rapidly and has become a good helper for our navy. From 022 missile boats, to 054 frigates, to 052C, to 002 aircraft carriers, Mingzhou Group has built a large number of advanced surface ships and achieved the goal of the navy. Modernization. Now, Mingzhou Group will help us modernize our underwater power!"

“Now, I announce that the construction of the 095 submarine has officially started!”

Following his command, the plasma cutting machine started, and the first submarine steel plate began to be cut. In fact, when it left the factory, it had already been rolled into the corresponding size. Now it is just the corners. After cutting, , the huge steel plate is sent to the three-roller plate bending machine.

As the name suggests, the main body of the three-roller plate bending machine is three rollers, which are divided into upper and lower structures. There is one roller on the top and two on the bottom. The length is the same. The steel plate that needs to be processed is sandwiched between the upper and lower parts. Among them, the upper roller can move up and down. By lowering, it can provide downward pressure on the steel plate. The steel plate is pressed during the movement, so that it can bend. The two lower rollers mainly rotate to allow the steel plate to bend evenly. , However, if you want to press an asymmetric structure, the two lower rollers must also be able to move and move horizontally to provide different support forces for the steel plate, so that steel plate materials with different curvatures can be obtained.

Plate bending machines have many uses in the domestic metal processing industry. For example, factories such as boilers, chemicals, steel structures, etc. all need this equipment. They can also be produced domestically, but for a long time, the ones produced are ordinary ones. The symmetrical three-roller plate rolling machine does not have high pressure and cannot curl high-strength steel at all.

 After all, the greater the yield of the steel, the harder it is to roll it.

At this time, I watched the five-meter-wide steel being stuffed into the plate rolling machine. Under the action of the plate rolling machine, the steel was bent during the back and forth movement. Every time it moved, the bending arc increased. Everyone was Tsk-tsk.

"For a long time, foreign countries have imposed an embargo on us in the field of high-performance plate rolling machines." Qin Tao introduced to everyone on the side: "Without plate rolling machines, advanced submarines cannot be manufactured. Even Lao Maozi does not have advanced plate bending machines, which makes them constrained in the production of nuclear submarines. Although their Typhoon-class nuclear submarines are large, they are not integrated. They use two separate pressure-resistant shells. Therefore, regardless of the Typhoon-class There’s a lot of displacement and there’s not really a lot of space inside.”

 Lao Maozi doesn’t have a high-performance bending machine. How can he build one with such a large underwater typhoon-level displacement? The answer is separation!

A large number of missile vertical launchers are arranged in the center of the huge hull. Ordinary nuclear submarines stuff these missile launchers directly into the pressure hull, with at most a section exposed on top to make a turtle back. What about the Typhoon class? Simply place it directly in the middle of the pressure shell!

On both sides of its huge hull are two independent pressure-resistant cabins, arranged in parallel on the left and right. Each cabin is 7.2 meters in diameter, with a total of 5 living cabins and 19 compartments. In the middle of these two pressure-resistant shells is the missile vertical launch device. This eliminates the need to open a hole in the pressure-resistant shell and has good strength. It can be regarded as an idea of ​​Lao Maozi.

(To be honest, the Hero of East China really doesn’t understand. Lao Maozi has the largest hydraulic press in the world. The Airbus landing gear has to be sent to Lao Maozi for forging. The plate bending machine is mainly a hydraulic press. Lao Maozi is What you can’t make yourself.)
