"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, my mind went crazy
They are all blank. I never thought that future warships would look like this."
"Of course they are tricking others." Qin Tao said with a smile: "If they take it seriously and follow this path and spend tens of billions, they will 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, and the rear nine
There are plans to retire all the ships in 2023. After a long time of working on them, there were a lot of new concepts, but it turned out to be a trap! It’s better to just play with destroyers and frigates honestly.
As for the ddg1000, this thing is indeed good, but it is too expensive. The Americans simply 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
If you spend 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 some people. Besides, those are all external things. How the shell changes is secondary. What's important is the internal things."
"What's inside?"
"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 ask for help."
Wuchang Shipyard? Why would this shipyard located in the inland come to 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 because of 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 to you. This is Li Lianyou, the designer of the 035,039 submarine, and 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 me about the 039 submarine?"
Although Qin Tao brazenly calls his 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 put forward many requirements: water drop shape, seven-bladed large canted propeller, digital display equipment, advanced weapon systems, etc.
A book-chasing app recommended to me by an old book friend I have known for ten years, the Changyuan app! It is so easy to use, I rely on it to pass the time by reading and listening to books while driving and before going to bed. You can download the anyan app here]
Wuchong attaches great importance to this requirement and started research and development in the mid-1980s. At that time, it happened to be in contact with the West, so they visited the West to broaden their horizons. However, it was still too difficult for them, so they have been
The submarine was launched into the water in 1994, sea trials began in 1996, and sea trials continued until 1999.
During 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 wry smiles.
"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." Qin Tao is not used to these people continuing to go around. 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, reaching 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 don't do that.
, I always add the suffix after 039, which 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 very embarrassing to do this, and they couldn't care less about it. They just didn't know if Mr. Qin could help them?
After all, colleagues are enemies!
"There are many reasons for 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 along beside him, saying that he could solve the submarine's noise problem with just a few words was nonsense.
"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 have no objection, right?"
Zheng Ming was also speechless. He was not the one who was responsible for the situation, so 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 allow
The 039 submarine can be put into service as soon as possible, which is the most important project of the navy."
"Okay, then we will 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 feeling 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 from ten years ago.
"Overall, there are too many bulges on the surface of the submarine, which greatly affects the smoothness of the submarine's surface. 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 there is a thin one above. It looks like a step from the side. 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 was made into this shape? Even if the front is wrapped, the noise will be smaller than 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 from the past that is 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. This is a big problem."
"Now that it has been designed, there is no other way but to think of other ways. By the way, has your submarine been equipped with silencer tiles?"
The two shook their heads.
"Then lay a layer of silencer tiles. This should improve the quietness performance."
Nothing else can be changed, 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, later 039s began to fully lay out silencer tiles, but the first 039 did not yet 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 by ten bel.
, it should be no problem to lower it by two or three bel. We can study other improvement plans together after the submarine enters the dock."
"Okay, then we will contact the submarine. Can we enter the dock tomorrow?"
"So fast?"
"Yes, he is 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 confused.
"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.
Already."
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.”
When he came to help, Qin Tao didn't think too much about competition or anything like that. He had confidence in himself, and the reason why he agreed without any hesitation was of course because he saw Li Lianyou's head full of white hair.
This chapter is not over yet, please click on the next page to continue reading! This is an old man who has silently 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 clear at a glance 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.
. It just so happens that yesterday afternoon, a ship repaired in the dock had just been completed. Today, it was replaced with a submarine!
Along the direction of the hull, there are a row of drainage holes. 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 designed by Lao Maozi, but due to defects, Lao Maozi gave 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 and 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 designing this submarine, they examined many Western submarine designs, but they still couldn't get rid of it.
Dare to make truly drastic changes.
The large seven-blade 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 discovered by the reconnaissance satellites overhead.
"This kind of control tower is too high and will affect the stability of navigation." Kvasa continued to give instructions.
"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 is stuffed with something like a periscope snorkel, which can be extended more easily. Now, they feel a little embarrassed after being belittled by Kvasa, but if
When it comes to design ideas, there is also helplessness.
"No, no, it's entirely 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 involved 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 over 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.
Therefore, 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 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, with even more surprise in their eyes: "Is this a single shell?"
"That's right, 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 was very proud.
This was an opinion put forward by Mr. Qin, and it turned 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 will solve all the problems and be purchased by the navy in large quantities, even comparable 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? Currently, our domestic submarine construction 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 strength 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 products! Now even iron ore is their Mingzhou Group.
Zhou Group purchases directly from abroad, and other steel plants simply cannot compare.
After visiting the submarine production here, Li Lianyou felt extremely complicated. 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 seen 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.
So Mingzhou Group deceived foreign customers.
In this way, the advanced submarines produced will first be handed over to foreign customers for use.
Now all the technical parameters of the submarine will be exposed. Will the Navy like it?
If the navy doesn't want it, then we 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.”
When Li Lianyou said this, he had a wry smile on his face.
The first thing the Navy values is performance! Why else buy the Kilo-class? The parameters of this submarine are also known to the outside world, and Ah San is also using it. The reason why we bought it back is not because the domestic products are not good.
?
"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."
