"Mr. Qin, good news!" Qin Tao had just finished his trip to the capital and returned to Mingzhou. Zhao Ling, who had come back a step ahead, greeted him with a smile: "The 039b submarine we produced is famous!"
Famous? Qin Tao was also a little curious: "Why are you famous?"
"In a joint military exercise with the US aircraft carrier formation, this submarine successfully broke through the opponent's heavy defenses, rushed to the US aircraft carrier and then surfaced, shocking them!" Zhao Ling said excitedly: "
Now, this matter is being spread internationally, and currently only our submarines can do it, and other submarines simply cannot compete with American aircraft carriers."
"Of course." Qin Tao said: "Every weapon and equipment produced by our Mingzhou Group is the most advanced and can play a huge role in future naval battles! Taking advantage of this opportunity, we will also promote it well
A wave.”
039b was originally a foreign trade submarine. Taking advantage of this east wind, selling it again will definitely continue to increase our orders. It seems that Mingzhou Group’s third domestic shipyard should also be prepared.
In the country, there was originally only a local shipyard in Mingzhou. Later, it jointly established a shipyard with Sanhang Heavy Industry. Now that Sanhang Heavy Industry has withdrawn its shares, the Huating shipyard has become a sole proprietorship of Mingzhou Group. After that, it mainly produces liquefaction products.
air ships, and the slipway here is freed up to build other ships, especially warships.
But now, arc sparks are everywhere on the slipway, and the orders are still fully booked. We will have to accept a large number of foreign trade orders in the future, and we may not be able to produce them here.
"Yes, Mr. Qin, we should publicize it well. We have already made a publicity plan. Can you take a look?" Zhao Ling said.
Now that she has become the secretary of Mr. Qin of Mingzhou Group, she must do her best, especially when Qin Tao is away, she must show her ability.
Now, after hearing what she said, Qin Tao took over the publicity plan with satisfaction.
Newspapers, TV, especially Zhang Zhongshuo's program, as well as the Internet and other media will promote it together, and the specific content has been compiled. However, Qin Tao frowned when he looked at these publicity plans.
"Why, Mr. Qin, this plan is not suitable?" Zhao Ling looked at Qin Tao worriedly.
"True and false, false and true, this is the most appropriate publicity strategy." Qin Tao said: "Anyway, we are not publicly publicizing, it is other people who are promoting. We might as well set these data higher."
When it comes to deceiving people, Zhao Ling is still a little reluctant to do so.
"For example, in terms of the steel used in submarines, we can completely promote that we use advanced steel with a yield strength of 1,500 MPa, which is the best in the world," Qin Tao said.
Yield strength 1,500 MPa? Zhao Ling opened her eyes wide: "Is this too high? After all, the yield strength of the most advanced steel in the United States is less than 1,200 MPa."
"Why is it so high? We are always making progress in the pursuit of advanced materials. We cannot rest on our laurels. In the future, we will be able to have steel materials of more than two thousand megapascals. What does this mean now? We can leave it to military commentators.
Analysis shows that our submarine can get close to the American submarine because it dives to a depth of 600 meters and uses the ocean to cover its own noise. By the way, the sea area where the exercise is conducted is 600 meters deep, right?"
Zhao Ling nodded.
"Also, our steel not only has high yield, but also has excellent welding performance." Qin Tao continued: "It can be welded without preheating, or only requires simple preheating. The strength of the steel and the use of the steel
In all aspects, it has reached the most advanced level in the world.”
A few decades ago, the mainstream steel was still steel, with a yield strength of only three to four hundred MPa. After the 1950s, the United States began to use a large amount of martensite transformation-strengthened heat-treated steel, also known as hy series steel. These steels
It has high strength and good low-temperature toughness, but its welding performance is not very good and needs to be preheated in advance. Large American warships, especially aircraft carriers and submarines, all use hy series steel.
Now, Qin Tao just wants to let the outside world know that when it comes to steel for shipbuilding, he is the number one in the world! The performance of his steel far exceeds that of American steel.
What then? Let the Americans continue to catch up and surpass, and see if they can develop steel with the same performance.
Zhao Ling already understood Qin Tao's thoughts. She nodded: "Okay, I will make arrangements."
"Steel is just one of them. There are many subsystems. For example, we are also very strong in underwater silent performance. We have transitioned from seven-blade large side-inclined propellers to pump-jet propellers. Our underwater noise can
It is reduced to 90 decibels and is completely integrated into the background noise of the ocean. We are also very strong in AIP performance. We already have a new generation of more powerful Stirling engines, and we are also planning to use lithium batteries to replace existing AIP engines.
Some lead-acid batteries.”
Zhao Ling thought seriously: "Lithium batteries have greater energy density. If lithium batteries are really used to replace lead-acid batteries, it is really possible to improve the underwater endurance of submarines a lot."
What Qin Tao meant by these words was to deceive the outside world and make others take the wrong path. Now, the technical route of this lithium battery seems to be correct.
"Yes, if a lead-acid battery can enable a submarine to operate at low speed for four days, then a lithium battery can enable a submarine to operate at low speed for more than fifteen days. However, don't forget that lithium is an element with very active chemical properties."
Now, the energy density of lithium-ion batteries has reached the order of 100wh/kg, which is far more than two or three times that of lead-acid batteries. Under the same weight, lithium-ion batteries have more energy and have good charge and discharge characteristics. Except that they cannot be large
Except for current discharge, other aspects are completely surpassed.
In later generations, this value has reached two to three hundred, which is also the main factor in the continuous improvement of the endurance of electric vehicles. There are also some special batteries that have reached four to five hundred.
This chapter is not over, please click on the next page to continue reading! However, the disadvantages of lithium batteries are also obvious: they are more likely to explode! Once an internal battery is squeezed and damaged, or a battery circuit fails and is short-circuited, etc.
, will cause the lithium battery to burn, and then the entire battery pack will be ignited. Just think about it and you can imagine how magnificent the picture is.
Zhao Ling felt a chill in her heart. Qin Tao's goal was actually to turn the submarines of those deceived submarine manufacturers into useless pieces that could burn at any time.
Xu Zhengyang remained silent. Mr. Qin had already let this news out a long time ago. The islanders had been fooled, and now they were just continuing to cheer for this route.
"Wait a minute, if lithium batteries are so dangerous, then why are you still using lithium batteries in the electric vehicle route you proposed?" Zhao Ling looked at Qin Tao curiously. This is unscientific.
"The greater the number, the greater the danger. The number of lithium batteries carried by a submarine is dozens or even hundreds of times that of electric vehicles." Qin Tao said: "Moreover, we did not launch this product immediately, but
We are constantly researching the management technology of battery packs and developing special chips to monitor the batteries to make the battery packs safer as much as possible. Moreover, we are also developing larger lithium batteries to increase the battery capacity and reduce the energy consumption of the batteries.
The number of cells in the battery pack."
Zhao Ling nodded, Qin Tao's consideration must be very complete, so she doesn't need to worry about things unfounded.
"By the way, some very suspicious people have appeared outside our shipyard recently. They probably want to pry for information. In order to avoid leaks, I have issued orders recently. There is nothing special for our shipbuilding workers.
Try not to go out and only move around the slipway of the shipyard, the canteen and the dormitory of the family home," Zhao Ling said.
Spies have always been there, and they are always infiltrating. This cannot be prevented. The main thing is to improve the quality of the crew. But recently, as 039b has become famous, there are more people operating outside, including foreign intelligence personnel, media, etc., they all
Looking for more information.
"Well, your approach is appropriate. However, the ban cannot last forever and has to be relaxed. It is better to arrange some people to publicize what we just said. After those people get enough information, they can
I will leave." Qin Tao said.
Zhao Ling's eyes lit up. Yes, these false information were passed on, and Mingzhou Group could not be blamed afterwards. After all, these information were disclosed by the media and had nothing to do with their group!
Kill two birds with one stone and solve the problem perfectly.
At this moment, Xu Zhengyang received new news. He waited patiently for Qin Tao and Zhao Ling to finish talking about these things, and then said: "Mr. Qin, I just received the news that Boss wants to come to us to inspect the 039b diesel power plant."
submarine."
"Lao Ba? Of course you are welcome!" Qin Tao said: "Lao Ba is our true friend. If they want to order 039b, we can provide the best price."
"What if Lao Ba asks for more?" Zhao Ling asked.
Qin Tao glanced at his wife approvingly. Her wife's thinking was becoming more and more flexible, and she could immediately think of what might happen: "The most I can do is ask to start construction in their shipyard, and we can agree to it!"
Of course, this is also in line with Lao Ba's style. After all, Lao Ba has limited funds on hand. If he wants to spend less money to do big things, and also improve his industrial strength and employment rate, of course he has to build it himself.
They can all build the Air Force's Xiaolong fighter jets, the Army's Khalid tanks, and the Navy's frigates themselves, including submarines. However, is it appropriate to export this advanced submarine technology directly to Lao Ba?
Zhao Ling and Xu Zhengyang were both surprised. Can they agree to this?
"This is also in line with international practice. Laoba must order a sufficient quantity, at least five or more. The first few ships will be produced here, and the last few ships will be produced by them. By the time they can produce, it will already be five.
Years later, by that time, we will already have more advanced submarines, so even if we leave it to Lao Ba to produce, it will not matter. Moreover, Lao Ba can produce it himself, which can not only improve the industrial level, but also reduce the cost. They
It is also beneficial to us to have more submarines to fight against Ah San. We do not have nuclear submarines to lease to Lao Ba, so we can only improve Lao Ba’s strength in this way.”
After hearing Qin Tao's words, Zhao Ling and Xu Zhengyang nodded. Yes, if they think about it this way, it is really a win-win result.
This is not the first time I have dealt with Lao Ba. Take shipbuilding as an example. When Mingzhou Group developed an advanced frigate, it exported it to Lao Ba. However, the anti-aircraft missiles on it were changed from Hongqi-16 to Shiki.
Li, of course, that was just the first one. The missiles that Lao Ba ordered later were all made in A. The two missiles are completely interchangeable, and the fire control system does not need to be modified.
Now, Lao Ba is coming to order submarines again! This time, the leader of the team is still Mahmoud, whom Qin Tao knew before. An old friend who once led the order of frigates, met Qin Tao again, and Mahmoud also
very happy.
"President Qin, I am very happy to meet you." Mahmoud stretched out his hand: "We are grateful to Dongfang and Mingzhou Group. With your help, we have modernized our warships and our frigates are used very well.
Not bad, now they are the main force of our navy."
】
Ah San on the opposite side is building aircraft carriers one after another, but Lao Ba has no money and cannot support a navy of that level. In their equipment sequence, the frigates built by the Mingzhou Group are already the largest in displacement and the most advanced.
battleships, and the rest are the outdated Perry class. They rely on a small but capable navy to safeguard their maritime rights and interests.
"We are also very happy." Qin Tao said: "We look forward to more cooperation in submarines. Now, please take a look at our submarine production line."
Unlike shipbuilding, submarines are built in a closed workshop. After entering the workshop, Mahmoud and the officers he brought with him were stunned when they looked at the huge factory building.
"Mr. Qin, does building a submarine need to be in such a large closed factory?" Mahmoud asked.
"It can also be built in the open air, but in order to avoid being discovered by aerial reconnaissance and to prevent the steel from rusting, submarines are generally produced in closed workshops," Qin Tao said.
He knew what Lao Ba was worried about. Building submarines in this workshop was too expensive. If you want to build submarines, you have to build a factory first. This is a huge expense!
Seeing their worried eyes, Qin Tao said: "Of course, if you want to save costs, you can also build a simple shed." Qin Tao said: "Currently, our Mingzhou Group has a special construction plan for simple sheds. Compared with steel bars,
Concrete factory buildings save half the investment and half the time, and if they are not used in the future, they can be dismantled and sold for scrap metal.”
Mahmoud's eyes lit up, is there such a way? But what does Mr. Qin mean by this? Has he decided to export the production line to us? I haven't mentioned it yet!
"Mr. Qin, in the past few years, our underwater threats have become more and more serious. The Asan Navy has once again leased nuclear submarines from Damao. We also need advanced submarines to fight against them. Therefore, I learned about the advanced capabilities of your 039b submarine.
After the performance, we finally made the decision to purchase from you." Mahmoud also spoke frankly.
"Well, you didn't come here before. Was it because you were hesitant?"
Mahmoud did not hide anything: "Yes, in the past few years, we imported four Guishushen-class conventional submarines from France, which are also our Hanguo-class submarines. In the third Indo-Pakistan War, this submarine was very powerful
It made a great show, making a surprise attack on the west coast of Asan, sinking an anti-submarine frigate of the Asan Navy, and escaping from the Asan Navy's anti-submarine pursuit. Therefore, we were very satisfied with the French goods. Later, we purchased two more Agostas.
The Type 70 submarine also feels good. In the past few years, we have been inspecting French submarines and want to purchase its further improved model, which is the Agosta Type 90."
There is inertia in weapons sales. Once they get used to it, customers will continue to choose.
The original Guishu Shen-class submarine was purchased by Lao Ba on his own initiative, but this Agosta 70 type had some luck. In 1977, the Rainbow Nation was sanctioned due to domestic policies and ordered this type from France.
The submarine could not be delivered, so Laoba missed it. The two submarines were delivered in 1979 and 1980 respectively.
Lao Ba has always used French submarines, so he is used to French submarines. If there is no accident this time, he will definitely continue to choose French submarines. The French have long considered this to be their own business. After all, this kind of Ago
The Star 90 submarine is tailor-made for Laoba. Although they also actively promote it to other countries, the end user is Laoba.
Unfortunately, things have changed.
Lao Ba fell in love with Dongfang's 054 frigates and ordered a few. As a result, the Navy ran out of money, so it did not purchase such submarines in 1994, and continued to consider this consideration. This consideration will last for several years.
Time passed, and the French waited and waited. When they heard the news that Lao Ba went to the East to purchase submarines, they didn't know what they would think.
"Your choice is correct. Our 039b submarine has better performance than the Agosta 90 submarine in all aspects." Qin Tao said: "When the French are selling to you, they always show off their performance.
AIP system, right? In fact, their system is very dangerous. In addition to using liquid oxygen, they also need special ethanol as fuel. Ethanol is easy to volatilize. Once ethanol appears in the submarine, it is very likely that
leading to fire or even explosion."
Qin Tao will never show mercy when he needs to throw dirty water on others. Moreover, he is not wrong either.
If you want to increase the submarine's underwater endurance, you need a special power system that does not rely on air. The Mingzhou Group uses a Stirling engine, which requires an additional liquid oxygen tank to provide oxidizer, but the fuel only needs to be carried by the submarine.
Diesel is fine. This is already a mature aip system.
However, the French, who have always liked to pursue romance, also want to be unique on submarines. Compared with the Agosta 70, the biggest improvement of the Agosta 90 is the addition of a nine-meter-long AIP cabin.
The cabin is equipped with a closed cycle steam turbine AIP system developed based on the closed "Rankin" cycle engine.
The principle of this system is different from that of the Stirling engine. It is also an external combustion engine, but it uses a steam turbine solution. Specifically, after the liquid oxygen is oxidized, it enters the combustion chamber and burns ethanol. The high-temperature gas passes through the steam generator.
It is cooled and returned to the combustion chamber, and the steam generator turns into high-temperature and high-pressure steam after washing the heat, which drives the steam turbine to do work and drives the generator to generate electricity.
The only advantage of this method is low noise, but the disadvantage is that it is bulky and economical. And, most importantly, it also needs to use ethanol as fuel!
If the user is Lao Maozi, then Qin Tao will definitely say that this thing cannot be used, otherwise after going to sea, all the ethanol will be drunk before it is used. And here in Lao Ba, drinking is impossible, but an accidental fire is
possible.
Of course, what is more dangerous is the German fuel cell, which contains not only liquid oxygen, but also liquid hydrogen. If this thing explodes, it will be no joke.
Hearing what Qin Tao said, Mahmoud nodded: "Yes, carrying extra ethanol is a big problem, but the French are still very sincere. They not only exported the entire submarine to us, but also promised to let us produce it ourselves.
.”
The French are also sparing no effort in marketing. They plan to build three submarines. The first one will be built at the Cherbourg Shipyard of the French DS Company. The second one will be assembled from imported parts. France will provide parts and be assembled at the Karachi Shipyard.
Laoba Navy will build the next three ships by itself. With three ships, Laoba will have the construction capability.
Qin Tao nodded: "The French allow you to build it yourself, and of course we can, too. However, you have to think clearly. If the quantity built is too small, it may not be more cost-effective than purchasing."
"Why?"
"Because you lack relevant equipment." Qin Tao said: "If you want to build a submarine, you must have a plate bending machine. Do you have one?"
Of course this boss is gone!
"Think about it, if you get the design drawings of a submarine from the French, and then start construction in your shipyard, and at that time, you find that you don't have a plate bending machine, do you have to find the French to purchase it?"
Mahmoud nodded, this is natural.
"When the French offer you an absurdly high price, will you buy it or not?"
If you buy it, the price will be too expensive and Lao Ba will suffer a huge loss. If you don’t buy it, how can you produce advanced submarines without a plate bending machine? You will definitely be in a dilemma then.
Mahmoud was suddenly shocked. Fortunately, he had not cooperated with the French in purchasing submarines in the past few years when working on the 054 frigate project. If he had purchased one, he would have definitely fallen into a trap!
When the time comes, the French will definitely have to make a killing!
Thinking of this, sweat broke out on his back. Fortunately, Dongfang's 039b submarine was outstanding. They decided to come to Dongfang for inspection. By the way, they communicated with Mr. Qin to know how deep the water inside was.
"Mr. Qin, if we want to build it ourselves, can you provide a plate rolling machine? What's the price?" Mahmoud asked Qin Tao.
Now, when they come to the East to purchase, they actually have their own Xiaojiujiu. They want to use France's promise to bargain with the East. The French promised that we can build it ourselves. What about you? Will you give us this opportunity?
"Of course. What we can provide is a fully automatic plate bending machine. Its performance is better than that of French products, and its price is only half of theirs. However, are you sure you want it?" Qin Tao began to ask.
