Chapter 409 850 mm vertical launch tube

   Now that the power system at the back is finished, the next thing is the front.

   "Next, let's talk about other layouts, the location of the conning tower, the layout of the torpedo cabin, etc. I won't talk about it, I just want to make a few requests."

  Kwasha nodded.

With a displacement of 8,000 tons, the VM-5 reactor is almost the same as their 945 nuclear submarine, so there is almost no need to change it later, and various anti-shock and noise reduction technologies can also be used. The pump-jet propeller at the rear It was a difficult point, but it was left to Petrov to solve it.

   Now, they are concerned with the previous layout.

   "In the middle of the hull, there need to be 12 vertical launch units with a diameter of about 850 mm, which can be directly connected from the top to the bottom. I think it would be better to be next to the power cabin."

  His words confused everyone.

   "President Qin, are we going to build a multi-functional attack nuclear submarine or a ballistic missile nuclear submarine?"

   "Of course attacking nuclear submarines."

   "Then why carry a vertical launch unit?"

  In everyone's mind, attacking nuclear submarines only need torpedo tubes, and only ballistic missile nuclear submarines need vertical launchers.

   "Could it be a cruise missile attacking a nuclear submarine?"

When hearing this question, Qin Tao nodded with satisfaction: "That's right, that's it! Since the displacement has been enlarged to 8,000 tons, of course we need to add some of our unique cabins. Tube, it is used to launch cruise missiles."

Generally speaking, nuclear submarines are divided into two types: attack nuclear submarines and ballistic missile nuclear submarines. However, there is a third type of old man, which is cruise missile nuclear submarines, which are similar to Oscar-class big guys, and are specially used to carry anti-ship missiles to attack the enemy. aircraft carrier formation.

   "So, is this launch tube used to launch anti-ship cruise missiles to attack the enemy's aircraft carrier formation? What anti-ship missiles are going to be stuffed inside?"

  Qin Tao smiled: "I don't know."

have no idea?

   That's right, Qin Tao really doesn't know now. Because various advanced anti-ship missiles, cruise missiles, and even anti-ship ballistic missiles have not yet come out!

Qin Tao is just planning for a rainy day. It is useless now, but it will definitely be useful in the future. They design it now, wait for approval, and start construction. It is estimated that it will be a few years later, and they will serve for 20 or 30 years. At least they can reach 2020. That At that time, all kinds of advanced weapons came out, and it turned out that submarines could not carry them!

Submarines can also launch anti-ship missiles. Now domestic submarines are trying to launch YJ-81 anti-ship missiles. This missile is small in size and can be launched from a 533mm torpedo tube, so it seems unnecessary. of.

   But when you arrive, with brand new missiles, you will find that the torpedo tubes are not thick enough!

The diameter of 850mm mentioned by Qin Tao is also well-founded. The 055 of later generations uses this kind of launch tube, which can be stuffed with many things. Qin Tao is tentatively set at 850mm. The younger brother can also stuff it in, this thing is a real killer for an aircraft carrier!

The original Dongfeng 21 has a diameter of 1.4 meters. Later, in order to use it on the 055, it made itself thinner abruptly, and the range has also shrunk to about 1,000 kilometers, but it doesn’t matter. This kind of big killer can be used as a deterrent Enemy carrier formations.

   It is used on the 055, and of course it must be used on the submarine.

   Get it ready now, and you don't need to modify it when you use it later.

(I saw a saying that the shape of the 093 turtle's back is not a hanging hair, nor a towed sonar, but an integrated nuclear reactor that can't fit. I was shocked. The position should be one-fifth of the hull by visual inspection. The second place, three-fifths of the volume at the back, is it the nuclear reactor and the power system? Or do you mean the crew lives on the bottom of the submarine?)

  Countless people are shocked, it can't be used, Mr. Qin, it can't be used, so what are you talking about here?

  However, no one dared to question it. Since Qin Tao said everything, they designed it according to this plan.

"Boss Qin, do you have any other requests?" Kwasha asked. In the last action, Kwasha had already completely admired Qin Tao. Now, he listens to whatever Qin Tao says, maybe now I don't understand, but it will definitely be useful in the future.

   "There are no others for the time being. Let's design according to these ideas first. Everyone, show your true skills and let the superiors see the strength of our third design office!"

  Qin Tao is full of expectations.

   As for the hat on the conning tower, you can change it later. These are trivial matters. The key is to design the main body of this submarine first.

  From this day on, everyone has entered into intense work. They have already become proficient in using computers to draw, which is convenient for design and modification. However, their workload is still heavy.

  Kwasha has long planned to make modifications on the basis of the already mature Type 945, so the final shape of this submarine will still be very similar to the Type 945.

  Two days ago, Qin Tao helped coordinate with the design department, but on the third day, something new happened.

   "Mr. Qin, there is a foreign customer who wants to order high-strength steel from us." On the phone, Zhang Jinxi, the person in charge of the steel plant, was a little excited: "This is the first time our steel has gone abroad!"

  Now, the steel of Mingzhou Iron and Steel Works has been used in many ways, not only for Mingzhou Group itself, but also for brother units to order. However, it has never been exported in terms of export.

  Although Qin Tao plans to open a new shipyard in Rainbow Country, this matter is still in progress, the process has not been completed, and they have not officially taken over. Steel exports have not yet started.

  Of course, those who melted the pressure hull of the submarine and then re-steeled it were not counted, and then used it on the Novorossiysk that was undergoing refitting.

   "Okay, congratulations." Qin Tao didn't care much at first, this kind of trivial matter is just to announce the good news to him, and his subordinates can handle it by themselves.

   "Yes, we are also very happy. Our steel plant can also directly export to earn foreign exchange. They asked us if we have 921A grade high-strength steel."

  When Qin Tao heard this sentence, he immediately became vigilant.

  921A is a special code name, this steel is only used on domestic nuclear submarines! Most people don't even know how powerful it is.

   It seems that it was the last action that made some people nervous. They wanted to find out more news, so they turned their ideas to their own side!

   After all, the steelmaking technology of Mingzhou Iron and Steel Works is already far ahead in the country, so they were targeted.

  This customer is fake when he comes to buy steel products, but it’s true that he wants to inquire about information!

   "Then how did you answer?"

   "I said, what is 921A steel? The steel we produce now is much more advanced than that kind of steel!"

   "Well, hold them steady, don't say anything, wait for me to pass."

   Putting down the big brother, Qin Tao had a smile on his face: "Zhengyang, let's go, let's fool people!"

  Xu Zhengyang's eyes also brightened.

Going out with Qin Tao, no matter what you do, will be colorful, but if you stay in the design department, then Xu Zhengyang will be suffocated. Although he also knows some technical knowledge, it is only superficial. Now he looks at these things all day long. When the technician was working on the design, he felt his head was about to explode.

  Fudge people, who are you fooling?

   You will know it when you arrive.

  Mingzhou Iron and Steel Works.

  With a smile on his face, Zhang Jinxi looked at the guests in front of him: "Everyone, it is a great honor to be recognized by you. Our President Qin will come over soon. When the time comes, please ask him to communicate with you in person."

"Our Owen Shipyard is also looking forward to cooperating with you. This time, we need the highest strength steel plate. We came here especially, hoping to get what we want from here." A middle-aged man named Lesk Said.

   "Yes, thank you for your trust."

   While Zhang Jinxi was going around patiently with the other party, Qin Tao finally came over.

"Mr. Qin? Nice to meet you. You are famous in the shipbuilding industry. In particular, you have begun to expand globally, and you have also acquired the shipyard in the Rainbow Country. Our Owen Shipyard may one day be taken over by you." Acquisition."

  Irwin Shipyard?

  Qin Tao understood immediately. On the surface, this shipyard belongs to Maple Leaf Country, but in fact, Maple Leaf Country has to listen to the United States in the south no matter what happens, which is also their consistent policy.

  This time, when they came over, the mastermind behind it was about to come out.

   "Really? Then I also look forward to such a day." Qin Tao's words wiped out the sky. He was just being polite, so why should Qin Tao take it seriously?

   "Boss Qin, this is Leske, an engineer from the Owen Shipyard in Maple Leaf Country. They are currently building a special ship and want to find the strongest steel in the world, so they found us." Zhang Jinxi smoothed things over.

"Yes, we need to build an icebreaker. I hope that the strength of this steel is as high as possible." Lesk said: "You can even produce Invar steel, and you can also build warships. We believe that you must have the most advanced steel."

   "Yes, of course we have advanced steel products, such as 921A steel products, they are all child's play in front of us, but they are very expensive!"

   "Really? How expensive?" Lesk asked Qin Tao.

   "Five million dollars a ton."

   What Qin Tao said made Zhang Jinxi almost cry out in fright, five million dollars a ton?

Ordinary steel plates for ships cost three to five thousand RMB per ton. Warship-grade steel plates cost around ten thousand to twenty thousand, not counting invar steel. The most expensive high-strength steel plates they produce cost 200,000 RMB per ton. Tons, sold to brother units, will not exceed 500,001 tons.

What now?

   Now it costs five million, or US dollars?

   President Qin is too daring to ask for it, right?

   Sure enough, after hearing what Qin Tao said, Lesk was also a little nervous: "Mr. Qin, isn't the price of this steel plate too expensive?"

   "Expensive? Then you buy American steel, HY80. It seems that there is still HY100. These steels are also high-strength steels. Why come to us to buy them?"

  Lesk gritted his teeth: "Then, we hope to get a sample and test the strength. If it meets our needs, we will order again."

  Qin Tao shook his head: "Of course not. We will issue a steel quality report. We can guarantee that the steel produced can fully meet your requirements. However, we do not provide samples, and the minimum price is ten tons."

  Do not provide samples, but sell at ten tons?

  Boss Qin said that, the other party should just stand up and leave, right? Zhang Jinxi was a little worried. If it got out, his reputation might not be good, right?

   You can’t discredit the group, you will have to mess around in the international market in the future!

   Sure enough, Lesk stood up: "We cannot agree to your conditions, the price is too expensive, and we still don't give us samples for testing."

   "Then please, after all, the steel of two gigapascals cannot be bought in any place."

   What, two gigapascals?

Zhang Jinxi felt his heart beating faster. After all, since he became the person in charge of the Mingzhou Iron and Steel Plant, he has been conscientious and down-to-earth, and has never gone out with Qin Tao. Therefore, his understanding of Qin Tao is limited to occasional visits. There was a meeting at the Mingzhou Shipyard. How could I have heard of Qin Tao running the train with his mouth full.

   Does a two-gigapascal steel plate exist in this world?

  Zhang Jinxi, a master steelmaker, thought it was impossible.

   After all, even the deck steel used on aircraft carriers in the United States is only 800 MPa, and the one currently under study is said to be 1 gigaPascal. And the most advanced steel that their Mingzhou Iron and Steel Works can produce at present, that is, about 700 MPa, the output is still very low, and they are still continuing to research.

  Who would have thought that President Qin actually said two gigapascals?

   (I checked some information and said that we have developed a 2200 MPa, which feels like bragging.)

  Lesk was also moved.

  Two gigapascal steel? His subconscious reaction is also impossible. However, if there is no such high-strength steel, how can the submarine being chased at sea dive to a depth of 600 meters?

   Moreover, there is obviously a margin for that depth. To be able to dive to this depth, either titanium alloy or super steel will be used.

   Could it be that the steel technology here is already more advanced than that of the United States?

  If it is of this level, then five million dollars per ton is acceptable, after all, its performance is comparable to that of titanium alloy!

"This level of steel is also very important to our country, and it is absolutely not allowed to be exported, but we are a private enterprise, we must consider survival, we want to make money, so I will come here in person. "Qin Tao said: "However, if we want to complete this business, we have to transfer several times to be safer. If we sign an agreement with you, it will be under the name of another company."

   "Boss Qin, I request a test for me. As long as I can see the test results, we are willing to buy ten tons."

  Anyway, the employer behind him gave the money, he was just running errands.

  Qin Tao nodded: "Of course, but please be mentally prepared. Once the deal is concluded, we will never admit that we have made such a deal."

  Lesk nodded: "Okay."

  Mingzhou Iron and Steel Plant, Inspection Department.

  Any steel factory will set up a special inspection department to test various raw materials and various finished products.

Of course, the testing equipment does not need to be very large, such as this yield strength testing machine, a small machine is a desktop machine, a column on the left, two fixtures, used to clamp the object, and then test, there is an operating device and The display interface displays various measured data.

  Mingzhou Iron and Steel Plant’s equipment is large. This yield strength testing machine is directly poked on the ground. It is as tall as a person, and it can sandwich a table-sized steel plate in the middle for experiments.

  Xu Zhengyang pushed the trolley with the steel plates for testing on it, and pushed it all the way to the testing machine.

   "The surface of this steel plate..." Lesk looked at the shiny surface curiously, a little curiously.

   "Galvanized steel sheet." Qin Tao briefly introduced.

  Zhang Jinxi opened his eyes wide.

   What galvanized steel plate, this is clearly a titanium alloy plate, okay?

   This thing was originally bent, but it was flattened after being placed on the plate rolling machine and operated back and forth a few times.

  Because it was stored for a long time, a layer of oxide appeared on the surface of the board, which looks similar to galvanized sheet. As for the edge, I don’t know how it was treated, but it looks a bit like ordinary steel plate.

  Lesk intends to touch it with his hand, but Qin Tao stops him: "I'm sorry, I can only look at it, not touch it."

  Keske had no choice but to give up.

  The steel plate was clamped up. The experiment officially begins.

  Lesk's gaze was fixed on the screen, and the numbers on it were jumping rapidly.

   Seven hundred, eight hundred, one thousand!

  One gigapascal, this is already the most advanced steel that can be produced in the United States!

  And the special steel plate in front of me is still as stable as Mount Tai!

   One thousand three, one thousand four, one thousand five...

  Lesk's eyes were filled with surprise, he witnessed a miracle!

  The steel plates produced by Dongfang have the most advanced technology!

   One thousand sixteen, one thousand six hundred two, one thousand six hundred three...

   Click!

   At this moment, the test sample made a sound, and a crack appeared on the surface.

  The machine stopped working.

"I'm very sorry, the quality of our batch of steel plates is not very stable." Qin Tao said: "However, this one should be a defective product. Other steel plates, even if they do not reach 2 gigapascals, can still It reaches 1890 MPa."

  Qin Tao felt a little embarrassed when he said this.

The cowhide is not blown, the train is not pushed, there is no two-gigapascal steel plate, and there is no two-gigapascal titanium alloy plate. This kind of titanium alloy plate dedicated to the nuclear submarine of this old man can only support it until now. degree.

   "Forget it, the quality is not stable, you should not buy it, let's just pretend nothing happened." Qin Tao shook his head.

  Who would have thought that at this time, Lesk insisted: "No, Mr. Qin, we are willing to buy!"

  Even if it does not reach 2 gigapascals, it is only more than 1600 megapascals, that is powerful enough! After they buy it back, do some research, maybe it can also promote the progress of their own steelmaking technology?

   It is normal for this kind of advanced steel to be unstable in quality. If it really reaches two gigapascals during the test, then Lesk really suspects that there is something wrong with the machine. Now, the data does not meet the standard, but he is convinced!

   "No, no, we can't sell unqualified steel, isn't this a blow to our brand?" Qin Tao continued to shake his head.

   "No, no, you sell it. Didn't we say, sign another name? I will definitely not come to trouble you. No matter what kind of steel we buy back, we can accept it."

   "How embarrassing is this? Our price will not change again. After all, the cost of this kind of steel is not low."

  Zhang Jinxi is a little messy.

  Where has he seen such a scene, his outlook on life and the world will be completely subverted.

   The test is not up to standard, the data is not up to standard, this kind of fraudulent behavior will be strongly despised by customers, and now, the other party keeps asking to buy it?

  This is really Zhou Yu beating Huang Gai.

   "In the contract, such a clause must be added. If the test fails to meet the requirements, the claim will also be waived." Qin Tao said.

   "Yes, yes! Please rest assured that we are not that kind of rogue company."

  There is a kind of company in this world that specializes in buying fake and shoddy products, and then goes to court to make money in this way. At this time, Lesk immediately thought of Qin Tao's concerns, and patted his chest to promise: "However, I hope to buy these ten tons of steel immediately."

   "Of course no problem, as long as the funds are transferred to our designated third-party account, you can immediately take away the steel. You will handle the import and export procedures yourself."

   "Okay, I'll get in touch now."

  Lesk left with his men, leaving behind Zhang Jinxi who continued to be confused.

   "Boss Qin, where did we get this kind of steel?"

   "In the warehouse, what steel is similar to this sample?" Qin Tao asked.

   "We don't produce many galvanized sheets. It seems that only a batch of civilian steel sheets are galvanized sheets." Zhang Jinxi said.

  Galvanized sheets are not used in shipbuilding. Anyway, after the construction is completed, the outside has to be painted. Galvanized sheets are expensive and rarely used.

   "Then this batch."

   "However, the yield of this batch is probably only about two hundred."

"Two hundred is two hundred, which is not low. They have promised that even if the requirements are not met, they will not claim compensation. However, the appearance must be similar. Come on, let's take a look first. If it doesn't look like it, we will think about it later." Think of ways to."

  Zhang Jinxi felt a chill in his heart.

  Looking at Zhang Jinxi's timid look, Qin Tao smiled: "What's the matter? Conscience? Do you know the real purpose of their visit?"

  Zhang Jinxi shook his head. He just thought it was strange that icebreakers don’t need this level of steel. What are they talking about 921A steel, wait, is it?

   "They want to spy on our domestic advanced special steel R&D and production capabilities by purchasing steel, and then spy on the performance of our military products." Qin Tao said: "We can't be soft on this kind of opponent."

   "I just received news that there are foreign customers purchasing high-strength steel in various large steel plants in our country." Xu Zhengyang added from the side.

  Zhang Jinxi nodded, he finally stopped hesitating: "Boss Qin, I was wrong."

   "Boss Qin, after they get it, what if they go to another place to test and find that there is something wrong with this batch of steel?"

   "When they get it, they must find a way to ship it out as soon as possible. Don't worry."

  Five million a ton, ten tons is 50 million. After two hours, the money arrived in the account. Then, Lesk asked to see the steel, and transported it to the port by car overnight, and went through the export procedures.
