Chapter 408 Designing a Nuclear Submarine

Capital, Huanglou.

“President Qin, you have made great contributions this time, so the navy has decided to reward you.” A leader said to Qin Tao.

Qin Tao glanced at the other party: "This leader, how does the Navy plan to reward me? Millions are nothing to me, and tens of millions are just drizzle..."

Before he finished speaking, the other party took out a small red book and said, "There is nothing else but this."

"What is this?" Qin Tao took it and looked at it, and was immediately surprised: "Qualification certificate for equipment manufacturing unit? Don't we already have it?"

 At the beginning, when the 051C was being built, Wu Shengli went there in person and issued this kind of certificate to them. Now, the certificate has not expired yet, so there is no need to replace it now, right?

This thing is worthless, so the navy is using this to fool itself?

In fact, Qin Tao was just joking. If he can make money, he still makes money from foreigners. Therefore, even if the navy rewards him with millions or tens of millions, he will not take it seriously at all. There is no need. But, take this thing Isn't it wrong to come here to deal with people?

“Taozi, don’t act like a good guy even if you get an advantage.” Wu Shengli said, “You guys, Mingzhou Group, are no longer the same as before.”

 “What’s the difference?”

“After restructuring, you have become a private enterprise. Our navy has never issued an equipment contracting unit qualification certificate to a private enterprise. You are the first, and probably the last!”

  Qin Tao just reacted.

Taking advantage of the financial crisis, Qin Tao restructured the Mingzhou Group. After the transformation was completed, the Mingzhou Group became a completely private enterprise. Qin Tao alone had the final say and no one could shake him. No one in the Mingzhou Group can dictate Qin Tao's status.

 This is a new beginning.

 However, we are also facing new problems.

 Mingzhou Group is a private enterprise, can it build warships for the navy?

 Forget past orders, what about future orders?

 This certificate in front of me completely solved the problem of Mingzhou Group. Mingzhou Group has helped the Navy a lot, so the Navy has to express that everything else has to cost money, but this is the only one that doesn't cost money.

 So, both sides get what they need.

Qin Tao smiled helplessly: "Okay, since the leaders value it so much, what else can we say? Leaders, please rest assured that we will continue to overcome obstacles in the Navy's ship project, move forward indomitably, and surpass the Other fellow submarines are brought to the Navy."

Hearing Qin Tao's words, Wu Shengli smiled: "Taozi, you don't have to express your position in a hurry. Please read this certificate carefully first."

 Look carefully?

Qin Tao looked at the certificate as if it was no big deal, and then looked at the copy. There, there was a dense form with the scope of the contract written on it.

 When Qin Tao scanned the writing on it, he was immediately surprised.

“Submarine? Are we qualified to undertake the manufacture of submarines for the Navy?”

The previous certificate did not include submarines, but this time, it included submarines, not only conventional submarines, but also nuclear submarines!

Looking at this copy, Qin Tao felt happy. This shows that Mingzhou Group can manufacture all naval equipment!

"That's right, you and the Pyramid State have almost reached discussions on the diesel-electric submarine project. The Navy is very concerned about this. After the diesel-electric submarine is manufactured, the Navy will send people to test it with the submarine. If the performance can meet our needs, Then the Navy will also order related submarines. As for the number, it will be called 039B as you said. As for nuclear submarines, the Navy plans to hold a hearing recently. Isn’t your Mingzhou Group’s Third Design Office very awesome? Is it suitable? You can tell us about the nuclear submarine project."

 Nuclear submarine!

 Finally going to build a nuclear submarine!

Qin Tao was also full of excitement. He looked at Wu Shengli: "Don't worry, we will definitely complete this project within a month. Is it okay to hold this hearing in a month?"

Wu Shengli nodded.

“So, can some information about related parts be given to us for review? If not, then we can only assume it for the time being.”

As for surface ships, all kinds of advanced weapons and equipment are inseparable from Qin Tao, so Mingzhou Group is naturally qualified to obtain these technical materials.

  However, underwater submarines are different.

 So far, they have not had access to relevant domestic information. Even if they have excellent submarine designers, they are not omnipotent. They must have relevant supporting weapons information.

 Submarine designers can only carry out overall design. Even if there is no relevant data, the overall design will not work. Without the design data of nuclear reactors, sonar, torpedoes, etc., how can we design a submarine?

During this period of time, even though Krasnopolski has attended nuclear reactor-related meetings many times, introduced his experience, and inspected the domestic nuclear reactor industry, however, that was only superficial. Nuclear submarine reactors have never been touched.

“Then you must ensure that everyone in your third design department will stay in the country and never leave again, just like Mao Gengxin and others.”

Of course, the Navy welcomes these old and excellent submarine designers, but if they are to be exposed to more secrets, their loyalty and reliability must be ensured.

Qin Tao nodded: "Of course, their term at Celestite Design Bureau has ended for several months, and they have not left. They have long been accustomed to life here, and even if we drive them away, they will not leave. "

Qin Tao has already laid the groundwork for this, and now everything will naturally fall into place.

 One day later, the Third Design Office of Mingzhou Shipbuilding Industry Group.

"Everyone, we are holding this meeting today and there are important things to be announced." Qin Tao looked at the dozens of old men present. These are all from the Celestite Design Bureau, Kvasa and Krasnopol. Ski, sat on the rostrum with Qin Tao.

"Our current project has come to an end. We asked you to come here originally for our deep-submersible lifeboat project. Currently, this project is going very successfully, and we are very satisfied with the experimental results. In addition to this project, we also We have designed a special diesel-electric submarine for export." Qin Tao said: "There is no such thing as a banquet in the world, and today's meeting can be regarded as a farewell party."

"Oh no."

 “Yes, we want to stay here.”

 There was a burst of noise immediately below.

 Just kidding, why are you going back now?

Red Solmovo Shipyard has given up the submarine business, and their Celestite Design Bureau is about to close down. Are they going back to driving taxis?

They have food, drink and wages here. It is simply heaven.

 No one wants to go back.

 “Everyone, don’t want to go back?”

Countless people nodded, who wants to go back and suffer hardship now? Isn't that a fool?

“If you don’t want to go back, then you need to stay here and abide by the laws here. You cannot go abroad without the permission of the group, and you cannot reveal any secrets.”

This condition is very harsh. They are all free people. If they want to stay now, they must be bound by the group?

“If you don’t want to, you can leave now. The group will give you an extra bonus, and you can go back with this bonus. If you stay, you have to sign such a confidentiality agreement.”

“Excuse me, if we can’t go abroad, what will happen to our families?”

“Your family can take over and settle here together. I believe you have seen that life here is much more comfortable than life in Damao.”

“If I could bring my family over, I would choose to settle here.”

 “Yes, I do too.”

Many people decided to stay, but only a few people, after much deliberation, still felt that it was hard to leave their homeland and left the conference room. Someone immediately outside gave them severance packages and sent them to the plane.

“Since everyone is willing to stay, I can say something that you have often heard but rarely heard now.” Qin Tao looked at the people present and said, “From now on, we are comrades!”

Hearing this title, some people immediately burst into tears, and some people sighed deeply. It has indeed been a long time since they heard this title!

“We all come from all over the world and come together for the same goal. We are like-minded.” Qin Tao said: “Now, we will continue to work hard for the same goal!”

Monetary benefits alone are not enough, you must have ideals. Now, Qin Tao's deception is quite successful.

“Mr. Qin, do we have any new projects?” someone asked.

“This project is very familiar to everyone, that is.” Qin Tao looked at everyone present: “Design a nuclear submarine!”

 Design a nuclear submarine!

 Everyone is excited.

 This is what they do! If they return to China, they will definitely not have this opportunity. Now, they can continue to use their strengths!

“In addition to everyone present, our colleagues who worked together before will also join us. We need to design a modern nuclear submarine and submit it to the capital for bidding!”

 “That’s great, that’s great!”

“That’s right, I will stay here even if I can’t pick up my family!”

The faces of these people were full of excitement.

“Next, I will introduce the overall idea, and I will leave it to you to refine the specific plan.”

Qin Tao used to build aircraft carriers. He is very familiar with surface ships, but he has never been exposed to underwater ones.

 Therefore, professional matters are left to professionals, and Qin Tao is only responsible for providing ideas.

“First of all, the underwater displacement of this submarine needs to be limited to 7,000 tons, and it is best to compress it to 6,000 tons.”

For any ship, displacement is a crucial data. It directly determines the size of the ship, the volume of its contents, etc.

At this time, Krasnopolski finally couldn't help it anymore: "Qin, for a multi-functional nuclear submarine, the displacement of seven thousand tons is a bit small. If it can be enlarged to eight thousand tons, the internal space will be If it is greatly increased, the layout will be more convenient."

There was embarrassment on Qin Tao's face: "Yes, it would be better if the displacement could be larger. However, our current domestic mature nuclear reactors only have a maximum power of ten megawatts. The new generation of nuclear reactors currently under development A nuclear reactor can only reach 28 megawatts. Even if this kind of power drives a 7,000-ton submarine, it can only reach a maximum speed of 25 knots. If it is an 8,000-ton submarine, the maximum speed can only be 20 knots. .”

There is nothing we can do about it. Any military equipment will be restricted by the heart. Without an advanced power system, it will be restricted by others.

Taking this nuclear submarine as an example, if the nuclear reactor is not powerful, then everything is in vain.

“Then why don’t you increase the power of the nuclear reactor?” Krasnopolski asked.

improve? Of course I want to improve, but the problem is, this thing is not that easy to improve!

Qin Tao looked at Krasnopolski: "What do you think?"

“We can transplant the VM-5 pressurized water reactor used on the 945 nuclear submarine. This reactor has a power of 170 megawatts. It can also reach a speed of 35 knots by pushing an eight-thousand-ton nuclear submarine.”

 170 megawatts! The power of this nuclear reactor is equivalent to the current 17 nuclear reactors. In this way, the displacement of the nuclear submarine increases and the speed also increases!

An underwater speed of 35 knots is a figure that domestic submarine designers cannot even imagine!

  After all, this kind of nuclear reactor is considered the most advanced nuclear reactor in the Lao Maozi era. Even the Typhoon-class nuclear submarine with a displacement of tens of thousands of tons uses two such nuclear reactors, but the power is further increased to 200 megawatts.

Qin Tao swallowed and said, "Comrade, are you sure?"

 Krasnopolski is Lao Maozi’s excellent nuclear reactor designer. However, an excellent nuclear reactor is definitely not the work of one person, but the work of a large group of designers! Can Krasnopolsky replicate this nuclear reactor with his existing personnel?

"The equipment here is too advanced, so after I came here, although I had the opportunity to participate in various activities, I was still relatively lonely. When I had nothing to do, I took a few people to input this reactor model. Get a computer and then simulate it on the computer..."

Qin Tao swallowed, his eyes widened, and he looked at the old submarine designer.

 In the past, all kinds of research required experiments. For example, nuclear bombs and nuclear reactors had to conduct experiments to find rules. However, later, with the continuous development of computer technology, these can all be simulated by computers.

It can be found that the United States has not conducted any nuclear tests for a long time. Are they not developing nuclear weapons? Of course not, it's just that they entered the virtual world and simulated various nuclear weapons experiments on the computer.

 As for some poor and weak countries, they have no other choice but to continue to use dangerous nuclear tests to verify.

 The same is true for nuclear reactors.

If it is a brand-new nuclear reactor, you may need to build an actual reactor to find data and build a model. However, the existing nuclear reactors and the rules have been mastered, which can be input into the computer and simulated in the computer.

This requires a powerful computer system. Qin Tao has never been stingy in this regard. The computers equipped for each design office will be updated every one or two years, and they are still the most advanced models available on the market. .

Krasnopolsky was bored, so he input the VM-5 pressurized water reactor into the computer. It was impossible for him to remember all the data, but he could completely transfer a lot of data during the computer simulation. After calculation, even after computer simulation, the resulting model will be more complete!

Although relying solely on computer simulations will still be very risky, Qin Tao has always been adventurous. If he has to wait until he is 8% sure to do anything, it will be too late.

“Okay, let’s make a design based on this VM-5 nuclear reactor and increase the displacement to 8,000 tons.”

Although Wu Shengli did not say anything, Qin Tao also knew that the country was not satisfied with the performance of 091. Subsequent research and development is continuing, and the 093 project may have begun.

 They cannot stick to the rules. If the project they produce cannot be different from 093, what is the point? What they are going to do must be ahead of its time!

With a displacement of more than 8,000 tons and a speed of 35 knots, this kind of submarine can shock those people if it is planned to be sent to Huanglou!

Thinking of this, Qin Tao felt a little carried away. Of course, he did not forget his mission.

“There is no problem in reducing the power of the reactor slightly, but we must pay attention to the noise level. This kind of reactor must achieve natural circulation at low power.” Qin Tao made the request.

The reactor is the same as the boiler. It boils water. The steam will go out, enter the heat exchange device, or directly drive the turbine, and then return to the reactor. In this cycle, a water pump is needed, and this water pump is a big noise maker. .

 In order to make the submarine quieter, you need to find a way to turn off the water pump.

 When running at full power, it may not be possible to turn it off directly, but at low power, if the circulating water pump can be turned off, it will be of great benefit.

“We have experimented that at low speed, the main circulation water pump can be turned off without any impact. If possible, we can also build a land experimental reactor.”

 Simulating on a computer only costs a little electricity. If you build an experimental reactor on land, it will cost a lot more.

  However, it is absolutely necessary to spend this money. If it succeeds, it will not only be a submarine, but it may also be used for nuclear-powered aircraft carriers in the future if it is modified based on it!

 (The power seems to be quite different, but we can improve it. It won’t be a useless thing like the Charles de Gaulle aircraft carrier.)

Qin Tao nodded. This nuclear reactor should be designed according to this design for the time being. After all, the technology is available. It would be a pity to throw it away. If it is not suitable, then we can continue to modify it.

  Anyway, their project must attract the navy's attention.

“We will report to our superiors.” Qin Tao said: “Then let’s talk about the power system. Is it difficult for us to use a pump-jet propeller for this submarine?”

 Pump-jet propulsion system!

 Hearing Qin Tao's words, everyone was surprised.

For a long time, the propulsion system of ships has been the most common propeller. However, with the advancement of processing technology, the propulsion system of submarines has also continued to develop, from the initial three-blade propeller to the five-blade propeller, and then to the widely used seven-blade propeller. The leaves are large and oblique.

 At most it can develop to nine leaves, but it has reached its limit and no further progress is possible.

In order to further improve the propulsion efficiency of submarines, the British first made an attempt to equip the "Trafalgar"-class attack nuclear submarines built in the 1980s with a new type of pump-jet propeller. , and has since then led the world.

I have to say that a skinny camel is bigger than a horse, and the old industrial countries still have a few tricks up their sleeves. Things like all-electric propulsion were first developed by the British. Regardless of whether they are mature or not, their innovative spirit is worthy of recognition.

To put it simply, it is like adding a sleeve to the previous propeller to wrap it up. In this way, it changes from an ordinary propeller to a water pump. (Of course, this is just an analogy. In fact, the propeller inside has two parts, the rotor and the stator.)

 What are the benefits of it?

Just like the tail nozzle of a jet engine that can concentrate exhaust gas, the efficiency of this pump jet propeller is very high, even reaching 0.85.

 Of course, efficiency is not the most important thing. What is important is that its silent performance has been further improved.

  No matter how the propeller is designed, it always makes noise and is covered with a cover. The scientific name of this thing is called an annular duct, which gradually shrinks backwards. It can not only gather the water flow, but also shield the noise. In this way, the silent ability of the submarine will be further improved.

Of course, there are also disadvantages. After such a toss, its weight is two or three times that of the original propeller. With such a big thing hanging on the back of the butt, it will be too strong a test for the submarine's trimming and other capabilities.

 Without excellent designers, this kind of thruster would simply not be possible.

At this time, Qin Tao has already proposed that if we want to do something, we must do the most advanced things in the world!

“Mr. Qin, we have tried this before, Petrov has tried this kind of thing before, Petrov!”

The next person stood up: "Mr. Qin, I am willing to take on this design task! However, in order to verify its efficiency, I need to do a lot of experiments and also need advanced processing equipment."

Although this thing is wrapped, there are also blades inside, and it also requires advanced multi-axis CNC machine tools.

"Of course there is no problem. After you design it, you can hand it over to our machinery factory in Huating for production. In the future, you can meet old acquaintances there."

 It was inconvenient to say it before, but now that we are all gay, of course we can say it openly.

Has that melancholy technician become a game master now?

 Life is like a play, and play is like life.

I have been feeling dizzy for more than a week, and my ears occasionally buzz. I almost fell back when I got up in the middle of the night. I went to the hospital, and the doctor said it was because I was tired. Alas, I am too old to withstand the wind and waves. This month I will keep updating twice a day, please forgive me, but I personally feel that the content is exciting enough recently. After finishing the nuclear submarine project, we will go to Ermao's house to drive Varyag back.
