Chapter 557 039's first boat

"Mr. Qin, these ship models you designed are really advanced and revolutionary." Here, Zheng Ming said to Qin Tao with emotion: "When I saw these ship models you designed, I thought They are all blank. I never expected that future warships would look like this."

"Of course it's to fool others." Qin Tao said with a smile: "If they take it seriously and follow this path, they will spend tens of billions and find out that it is a big pit."

The Littoral Combat Ship sounds very high-end, but after burning tens of billions, it was found that this thing was useless at all. The first one was decommissioned after ten years of service. It is said that the aluminum alloy shell cracked. There are plans to retire all the ships in 2023. It took a long time to develop a lot of new concepts, but it turned out to be a trap! It's better to just play destroyer and frigate honestly.

As for the DDG-1000, this thing is indeed good, but it is too expensive. The Americans cannot afford such a high cost. They only equipped three ships and ended up hastily.

At first, the Americans used Star Wars to bring down the Red Empire. Now, Qin Tao is following the same pattern and constantly digging holes for them. As long as the opponent jumps down, they can spend a lot of money. The military expenditure is certain. Here After spending money, you have to save money elsewhere.

 Big hole?

Zheng Ming looked at Qin Tao in surprise. He didn't expect that Mr. Qin was actually trying to trick others!

“When we have nothing to do, let’s fool others. Moreover, those are all external. How the shell changes is secondary. The important thing is the internal things.”

 “Inner things?”

"Yes, for example, the warship's power distribution plan, which is the comprehensive power system we are currently developing, and the warship's detection, data processing and other information combat capabilities, these are the most critical." Qin Tao said : “In these aspects, we are currently catching up and even overtaking in corners.”

Qin Tao couldn't stop talking about this, but before he could tell his rich knowledge, Xu Zhengyang had already walked in.

“Mr. Qin, someone from Wuchang Shipyard came to our door and asked us for help.”

Wuchang Shipyard? What does this shipyard located in the inland want to do with us? Qin Tao felt a little strange, but he was idle anyway: "Okay, let's invite them in."

Zheng Ming on the side seemed to have thought of something and frowned: "Mr. Qin, should I avoid it?"

“No, Lao Zheng, maybe you can help me too.”

Two people walked in from the door. When they saw Zheng Ming, they were stunned.

“Old Li, Old Zhao, it is indeed you.” Zheng Ming said: “Are you here about the 039 submarine?”

Both of them looked a little embarrassed.

“Do you know each other?” Qin Tao was slightly surprised.

“Yes, Mr. Qin, come, let me introduce you. This is Li Lianyou, the designer of the 035 and 039 submarines. This is Zhao Heping, who is responsible for the construction of the submarine project at Wuchang Shipyard.” Zheng Ming said to Qin Tao.

“You two came to see me about the 039 submarine?”

Although Qin Tao shamelessly calls his own foreign trade submarines 039B, in fact, the Navy has never ordered a submarine from the Mingzhou Group. The main source of the Navy's submarines is the Wuchang Shipyard.

 From the original 033 to the current 039, they were all built by this shipyard.

For a long time, the Navy relied on the old 033 to dominate the world. Later, it modified the 035, but there was no radical change. Therefore, in the 1980s, the Navy decided to develop a new generation of conventional submarines, which were still Key projects.

The Navy has put forward many requirements: water drop shape, seven-bladed large canted propeller, digital display equipment, advanced weapon systems, etc.

Wuchong attaches great importance to this requirement and began development in the mid-1980s. At that time, it happened to be in contact with the West, so it also visited the West to broaden its horizons. However, it was still too difficult for them, so it was not until 1994 that the submarine was launched. Sea trials began in 1996 and continued until 1999.

 In this process, the Navy purchased a large number of Kilo-class submarines, indicating that it was not satisfied with the performance of this submarine.

However, Qin Tao didn't know where he was dissatisfied. He had to wait for the people in front of him to explain. After all, since they were here, it must be about this submarine.

Sure enough, after hearing Qin Tao's question, Li Lianyou and Zhao Heping looked at each other with a wry smile.

"Actually, we are peers, that is, competitors. Ordinarily we should not come here for help. However, we are all for the construction and development of the navy. Now we have encountered problems and want to come to you for help. I also hope that you can lend a hand. Come help."

 “What’s the problem? Just stop talking about it.” Qin Tao is not used to these people continuing to go around, and his time is also precious.

"The biggest problem with our submarine is that the silent performance is not up to standard." Li Lianyou said: "According to the original plan, the noise of our submarine is 20 decibels smaller than the previous one, reaching about 120 decibels. However, during the test, But it’s as high as 130 decibels.”

The original 033 submarine in China had a noise as high as 160 decibels, which was definitely an underwater tractor. Later, when it was improved to the 035, the noise was reduced by 20 decibels to about 140 decibels. Although there has been great progress, it is still not as advanced as the world's advanced level. There is a big gap, so the 039 submarine continues to work hard and wants to reduce it to 120 decibels, but this indicator cannot be achieved!

(Readers, please don’t complain. Isn’t our 039 very advanced? Why is it so noisy? There are many models of our 039, especially the subsequent models. They can be named with new numbers, but we are not so Damn, I always add the suffix after 039. This is a way to confuse others. The ship in the book now is the first ship in the entire 039 series, and its performance is indeed not very good.)

They made great efforts to solve the noise problem of submarines, but they still couldn't solve it. Thinking of the excellent performance of the submarines produced by Mingzhou Group, they were tempted, gritted their teeth, and decided to come to Mingzhou Group for help, even if it was It would be embarrassing to do so, and they couldn't care less. They just didn't know if Mr. Qin could help them?

 After all, colleagues are enemies!

"There are many causes of noise." Qin Tao said after thinking: "For example, whether the surface of the submarine is smooth, the shape design of the entire hull, the matching of the propeller, etc., these will all cause noise, so now if If you come to ask me yourself, I won't be able to give you an answer right away. I'm not a magician." Qin Tao said with a smile.

Zheng Ming nodded beside him. It was nonsense to solve the noise problem of submarines with just a few words.

"Yes, so we will show you the design drawings. If necessary, you can board our submarine, but this requires approval from your superiors. Lao Zheng, you should be okay with it, right?"

Zheng Ming was also speechless. He was not the one doing the soy sauce yet, he still had to take responsibility for them.

"Of course there is no problem. The performance of the diesel-electric submarines produced by the Mingzhou Group is more advanced, which does not involve the issue of leaking secrets. Moreover, the Mingzhou Group is also producing warships in large quantities. They have always done a good job in keeping secrets. This is also to let The 039 submarine can be put into service as soon as possible, which is the most important project of the navy."

“Okay, let’s show the design drawing to Mr. Qin.” Li Lianyou said, taking out a large-scale design drawing and laying it directly on the table in front of Qin Tao.

 Qin Tao couldn't help but lament that the level of domestic design departments still needs to be improved. It's already the 1990s, and they still use manual drawing.

However, considering that the design of the 039 submarine started ten years ago, it is understandable that this design drawing may also be ten years ago.

“Overall, there are too many bulges on the surface of the submarine, which greatly affects the smoothness of the surface of the submarine. Especially the command tower, why is it still trapezoidal on top? What is the idea behind this design?”

Qin Tao was a little speechless. Although he knew about this weird design of domestic submarines, when he actually saw it, he still had an unspeakable complaint. He couldn't come up with such a design until his brain was full of water. !

There is a thick command tower below, and a thin one above. From the side, it looks like a step. The connection between the thick and thin ones is a huge source of noise!

“Our command tower needs to install a lot of things, but we also want to reduce the size of the command tower, so we made it in this shape.” Li Lianyou explained.

“So it’s made into this shape? Even if the front is wrapped, the noise will be less than it is now.” Qin Tao said: “This kind of design should not exist.”

“Well, Mr. Qin is right, we shouldn’t have this kind of design anymore, it’s still the old thinking that’s causing trouble.” Li Lianyou nodded.

"Mr. Qin, how do we modify it? Do we need to cut it off here? This is equivalent to a major surgery, and we have to go back to the shipyard to modify it."

“If I modify it here, what should I do with the stuff there?” Qin Tao asked in return.

 “Yes, there is no place to put the things inside, which is a big problem.”

“Now that it has been designed, there is no other way but to think of other ways. By the way, have you installed silencer tiles on this submarine?”

 The two shook their heads.

“Then lay down a layer of sound-absorbing tiles, which should improve the quietness.”

 No other changes can be made, and the only option is to lay silencer tiles outside.

Li Lianyou and Zhao Heping looked at each other, and then continued to smile bitterly: "Yes, if a layer of silencer tiles can be laid, the silence of our submarine can be improved, but the submarine has already been launched into the sea for testing. If we drive back to our factory, we have to go upstream and have to walk a long way. And, more importantly, we don’t have the relevant technical reserves to lay silencer tiles.”

Of course, the later 039s began to fully lay out silencer tiles, but the first ship of the original 039 did not have this means.

“Then you need our help? That’s no problem. We’ll give you a quotation. If it’s suitable, you can bring the submarine to our dock and we’ll help put up the silencer tiles.”

The two of them were immediately overjoyed: "Thank you so much, Mr. Qin."

"Don't be too early, we are also doing business. Polishing aircraft carriers and tiling submarines are all the business of our Mingzhou Group, but you must be mentally prepared. Even if you put on silencing tiles, it may not be able to reduce the noise to ten decibels. , it should be no problem to reduce it by two to three bel. We can study other improvement plans together after the submarine enters the dock."

“Okay, then let’s contact the submarine. Can we enter the dock tomorrow?”

"So fast?"

“Yes, it’s currently in a nearby submarine base.”

After seeing the two people off, Zheng Ming said with emotion: "Mr. Qin, your selfless and noble character is so touching."

 Selfless?

 Qin Tao was a little puzzled.

"If they can perfect the 039 submarine, it will pose a threat to your Mingzhou Group. After all, you also produce submarines. The navy does not need many submarines. If you continue to order from them, your orders will be fewer. ”

What did Qin Tao think it was? It turned out to be this kind of concern. Qin Tao smiled: "I believe that what the Navy values ​​​​is the actual performance of the submarine. Our performance is the most advanced. The Navy should be able to keep its eyes open and see clearly. Which one is the best? Besides, even if the Navy doesn’t want it, we can still make money by selling it.”

Qin Tao didn't think too much about competition when he came to help. He had confidence in himself, and the reason why he agreed without any hesitation was of course because he saw Li Lianyou's white hair.

This is an old man who has quietly dedicated himself to the motherland's conventionally powered submarines. How could Qin Tao let him down?

 Besides, if they can’t solve the problem, they turn to Mingzhou Group for help. Isn’t it obvious who has the stronger technology?

the next day.

A submarine appeared in the No. 2 dock of the Mingzhou Group. This dock is an old piece of equipment from the Mingzhou Shipyard, but it still plays an important role. Whether it is shipbuilding or ship repair, the construction schedule is fully booked. of. It just so happens that yesterday afternoon, a ship repaired in the dock had just been completed, and today, it was replaced with a submarine!

A row of drainage holes are opened along the direction of the hull. As the seawater in the dock is pumped out, the seawater between the inner and outer shells of the submarine also flows out gurglingly.

Looking at the trapezoidal control tower, Kvasa shook his head repeatedly: "I didn't expect that in the 1990s, you actually still have this design! Inherited from 033, right?"

 The original 033 submarine had this kind of control tower, with a thick one at the bottom and a thin one at the top. This design was originally Lao Maozi's, but due to flaws, Lao Maozi gave it up long ago. Unexpectedly, Dongfang still uses it.

Since the Mingzhou Group is asked to help, the elite soldiers and generals of the Mingzhou Group will naturally come to follow the staff. Kvasa has been working on submarines all his life and is absolutely authoritative in this regard.

Hearing Kvasa's words, Li Lianyou was also a little embarrassed. Yes, they have never been able to get rid of the influence of the former 033 submarine. Even when this submarine was designed, many Western submarine designs were inspected, but they still couldn't get rid of it. Dare to make truly drastic changes.

The seven-blade large inclined propeller at the tail is wrapped. When you see the shape of this propeller, it is easy to infer the characteristics of water sound. After all, this dock is in the open air and cannot be detected by the reconnaissance satellites overhead.

“This kind of control tower is too high and will affect the stability of navigation.” Kvasa continued to point.

"Yes, Mr. Kvasa, your opinion is correct. However, if you want to lower this place, you must replace it with more advanced devices. In the era when we designed it, we still felt that the reliability of photoelectric masts was Probably not high.”

The extra length was filled with something like a periscope snorkel, which could be extended more easily. Now, they felt a little embarrassed after being belittled by Kvasa, but if When it comes to design ideas, there is also helplessness.

"No, no, it's all a design issue. Even if it's an ordinary mast, you can expand the space below and push the lifting mechanism directly to the bottom of the submarine. There's no need to make this kind of trapezoidal layout." Kvasa didn't criticize at all. Show no mercy.

“Mr. Kvasa, if it’s convenient, can we see how your submarine is designed and built?” Li Lianyou asked.

This involves business secrets. Kvasa did not answer, but looked at Qin Tao with questioning eyes.

“Of course it’s no problem, we can go now. I’ll take you there to have a look.”

This thing can't be learned just by looking at it. Li Lianyou has been working on submarines for half his life, and it's time for him to experience world-class submarine manufacturing technology.

So, under the leadership of Qin Tao and accompanied by Kvasa, Li Lianyou, Zhao Heping and others stepped into the submarine production workshop of the Mingzhou Group for the first time.

When he walked in, Zhao Heping sighed: "Your factory is so clean!"

The ground is spotless, there is no possibility of oil stains, and all the equipment is neat and tidy. When you walk in from this corner of the workshop, you will start with the plate rolling machine. At this time, the plate rolling machine is running, and the huge steel plate is slowly moving into a curved shape.

“Of course, we are a modern enterprise and of course we must have strict environmental requirements.”

"This diameter is a bit large. How big a pressure shell are you going to build?" Li Lianyou stared at the steel plate, his surprise growing in his heart.

 “There are sections that have been built over there, you can take a look.”

So, they walked over, and their eyes were even more surprised: "Is this a single-shell?"

"Yes, according to our plan, the submarine produced is a mixture of single and double hulls. This is also one of our characteristics and gives full play to the advantages of the two structures." Kvasa is very proud.

 This is the opinion put forward by Mr. Qin, and it turns out to be the most successful design!

"Compared with your submarines, our 039 is already outdated." The expression on Li Lianyou's face became lonely.

 They come here to ask for help because they can't solve the problem. At the same time, they also have expectations. They hope that their submarines can solve all the problems and be purchased by the navy in large quantities, even compared to the submarines of the Mingzhou Group.

 After all, they are the big brothers in the submarine industry.

 But now, looking at the modern indoor factories and the advanced submarine production, he has given up hope.

“The safety of a single shell is not high.” Zhao Heping also wanted to save something.

“So we’re using eight hundred megapascals of high-strength steel.”

 Eight hundred megapascals!

"How is this possible? Our domestic submarine construction currently uses the newly developed 921A high-strength steel, with a yield strength of only about 590 MPa. How could this kind of steel exist?" Zhao Heping didn't believe it.

Qin Tao smiled: "The strongest deck steel we can currently produce can already reach one thousand megapascals. The steel used on submarines has undergone some changes. Even if it is reduced to eight hundred megapascals, The intensity is enough."

Mingzhou Group is different from them. Mingzhou Group has its own steelmaking plant. They also have the most advanced steel research and development institutions. They have developed many advanced steel materials! Now even their Mingzhou Group purchases iron ore directly from abroad, and other steel plants simply cannot compare.

 After visiting the submarine production here, Li Lianyou had an extremely complicated mood. On the one hand, he was proud of having such advanced submarine production in the country, but on the other hand, he felt uncomfortable that his submarine technology was outdated.

Back at the dock, looking at his own submarine that was about to start laying silencer tiles, he felt that there was no need to waste time. All future submarine manufacturing would be left to the Mingzhou Group.

"Old Li, you don't have to be sad." Zhao Heping seemed to have figured out something and said to his old partner: "Although their submarines are advanced, they have begun to be exported. According to the requirements of our navy, their own performance must be kept secret, so , their submarine navy may not like it, but our submarines continue to improve, and they will definitely reach or even surpass the submarines of the Mingzhou Group!"

Submarines are underwater killers and the most important secret force of the navy, so they must be kept secret. Mingzhou Group originally obtained the submarine production equipment from Lao Maozi, but the navy had no money on the one hand, and was not very trusting on the other. Therefore, Mingzhou Group deceived foreign customers.

 In this way, the advanced submarines produced will first be handed over to foreign customers for use.

Now the various technical parameters of the submarine will be exposed. Will the navy like it?

If you don’t want the navy, you have to rely on military ships!

 Zhao Heping is still confident.

Li Lianyou looked at the old man: "Brother, your idea is too simple. How could Mr. Qin not leave a backup plan? If such advanced submarines are to be exported, the ones for personal use will only be more advanced. We, I think we will have to If we break up, maybe I’ll have to work at Mingzhou Group.”

 Li Lianyou had a wry smile on his face when he said this.

 The first thing the navy values ​​​​is performance! Why else buy a Kilo class? The parameters of this kind of submarine are also known to the outside world, and Ah San is also using it. Isn’t the reason why we bought it because domestic products are not good enough?

"Old Li, cheer up. You are the most famous conventional submarine designer in China. Both 035 and 039 are from your hands. How can you be discouraged? If we see the gap, then we will rise to the challenge and catch up and surpass. .”

Li Lianyou continued to smile bitterly: "Catching up and surpassing? I guess the gap between us may become wider and wider. Forget it, don't count on it."
