Now that we’ve talked about the power system at the back, let’s move on to the things at the front.
"Next, let's talk about other layouts, the location of the control tower, the layout of the torpedo room, etc. I won't go into details. I will just make a few requirements."
Kvasa nodded.
The displacement of 8,000 tons and the VM-5 reactor are almost the same as their 945 nuclear submarine. Therefore, there is almost no need to make any changes later. Various shock-absorbing and noise-reducing technologies can also be used, including the pump-jet propeller at the tail.
It was a difficult problem, but it was left to Petrov to solve.
Now, what they focus on is the front layout.
"In the middle of the hull, there need to be 12 vertical launch units with a caliber of about 850 mm, directly from the top to the bottom. I think it should be better to be next to the power cabin."
His words confused everyone.
"President Qin, are we going to build a multifunctional attack nuclear submarine or a ballistic missile nuclear submarine?"
"Of course it's an attack on a nuclear submarine."
"Then why carry a vertical launch unit?"
In everyone's impression, attack nuclear submarines only need torpedo launch tubes, while only ballistic missile nuclear submarines need vertical launch devices.
"Could it be a cruise missile attacking a nuclear submarine?"
When hearing this question, Qin Tao nodded with satisfaction: "Yes, that's it! Since the displacement has been enlarged to 8,000 tons, of course we need to add some of our unique cabin sections. These twelve launchers
Yes, 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, Lao Maozi also has a third type, which is cruise missile nuclear submarines, which are similar to Oscar-class big guys, 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 enemy aircraft carrier formations? What anti-ship missiles are planned to be stuffed in it?"
Qin Tao smiled: "I don't know."
have no idea?
That's right, Qin Tao really doesn't know yet. Because various advanced anti-ship missiles, cruise missiles, and even anti-ship ballistic missiles haven't come out yet!
Qin Tao is just preparing for a rainy day. It is useless now, but it will definitely be useful in the future. They are designing it now. When they get approval and start construction, it will probably be a few years later. It will be in service for 20 to 30 years, at least it will be 2020. That
At that time, all kinds of advanced weapons came out, but 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 later, with brand new missiles, you will find that the torpedo tube is not thick enough!
The diameter of 850 mm mentioned by Qin Tao is also well-founded. Later generations of 055 used this kind of launch tube, which can stuff a lot of things. Qin Tao tentatively set the diameter at 850 mm. In the future, even Dongfeng 21
My younger brother can also fit in. This thing is a real aircraft carrier killer!
The original Dongfeng 21 has a diameter of 1.4 meters. Later, in order to be used on the 055, it was made thinner and the range was reduced to about a thousand kilometers. But it doesn't matter. This kind of big killer can be used as a deterrent.
Enemy aircraft carrier formation.
It is used on 055, and of course it must be used on submarines.
Get it ready now so you don't have to modify it later when it's time to use it.
(I saw a statement saying that the turtle-back shape of the 093 is not a hanging hair or a towed sonar, but an integrated nuclear reactor that cannot fit inside. I was shocked. I visually inspected the position and it should be one-fifth of the hull.
Second, the three-fifths of the volume at the back are all nuclear reactors and power systems? Or do the crew members live on the butt of the submarine?)
Countless people were 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 had said it, they had designed it according to this plan.
"Mr. Qin, do you have any other requests?" Kvasa asked. In the last action, Kvasa had completely admired Qin Tao. Now, he will listen to whatever Qin Tao says. Maybe now
I don’t understand it, 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 your superiors see the strength of our third design department!"
Qin Tao is full of expectations.
As for the hat on the conning tower, it can be changed 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 become proficient in using computers to draw, which is convenient for design and modification. However, their workload is still very heavy.
Kvasa has long had a plan to modify the already mature Type 945, so the final appearance of this submarine will still be very similar to the Type 945.
In the first two days, Qin Tao helped coordinate in the design office, 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!"
Nowadays, the steel from Mingzhou Steel Plant has been used in many aspects. Not only Mingzhou Group uses it itself, but also its brother units will order it. However, when it comes to exporting, it has never happened before.
Although Qin Tao plans to open a new shipyard in Rainbow Kingdom, this matter is still being promoted, the process has not been completed, and they have not officially taken over. The export of steel has not yet started.
Of course, the batch of melting and remaking the steel of the submarine's pressure hull, and then using it on the Novorossiysk, which was being refitted, does not count. This project is secret and cannot be announced to the outside world, otherwise Ah San will not be too impatient.
This chapter is not finished yet, please click on the next page to continue reading the exciting content! "Okay, congratulations." Qin Tao didn't pay much attention to it at first. This kind of trivial matter was just to announce the good news to him, and his subordinates could handle it themselves.
.
"Yes, we are also very happy that our steel plant can also directly export and earn foreign exchange. They asked us if we have 921A grade high-strength steel."
When he heard this sentence, Qin Tao immediately became vigilant.
921A is a special code name. This steel is only used on domestically produced nuclear submarines! Most people have no idea how powerful its performance is.
It seems that the last action made some people nervous. They wanted to find out more information, so they decided to come here!
After all, the steelmaking technology of Mingzhou Steel Plant is already far ahead in the country, so they are being targeted.
This customer is here to buy steel, but it is true that he wants to get information!
"Then how did you answer?"
"I said, what does 921A steel mean? The steel we produce now is much more advanced than that kind of steel!"
"Well, hold them still, don't say anything, and wait for me to come over."
Putting down Big Brother, Qin Tao had a smile on his face: "Zhengyang, let's go and fool people!"
Xu Zhengyang's eyes also lit up.
When you go out with Qin Tao, no matter what you do, you will be rich and colorful. However, if you stay in the design office, Xu Zhengyang will be depressed. Although he also knows some technical knowledge, it is only superficial. Now he watches these all day long.
The technician was working on the design, and he felt like his head was going to explode.
Fooling people, fooling whom?
You will naturally 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, I am very honored to be recognized by you. Our President Qin will be here soon. When the time comes, I will ask him to communicate with you in person."
"We at Irving Shipyard are also looking forward to cooperating with you. This time, we need the strongest steel plate. We are here because of your reputation, and we hope to get what we want from here." A middle-aged man named Leske
said.
"Yes, thank you for your trust."
Just when Zhang Jinxi was patiently going around in circles with the other party, Qin Tao finally came over.
"Mr. Qin? It's a pleasure to meet you. You are well-known in the shipbuilding industry. Especially, you have begun to expand globally and have also acquired shipyards in Rainbow Country. Our Irving Shipyard may one day be owned by you.
acquisition.”
Irving Shipyard?
Qin Tao understood immediately. On the surface, this shipyard belongs to the Maple Leaf Kingdom, but in fact, the Maple Leaf Kingdom has to listen to the United States in the south no matter what matters. This is also their consistent policy.
This time, when they came over, the mastermind behind it was about to emerge.
"Really? Then I also look forward to such a day." Qin Tao's words made the whole conversation go away. They were just being polite, so why should Qin Tao take it seriously?
"Mr. Qin, this is Leske, an engineer from Maple Leaf Country's Owen Shipyard. 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. We hope that the strength of this steel is as high as possible." Lesk said: "You can even produce Invar steel and build warships. We believe that you must have the most advanced
of steel.”
"Yeah, of course we have advanced steel, such as 921A steel, it's just child's play in front of us, but it's very expensive!"
"Really? How expensive is it?" Lesk asked Qin Tao.
"Five million dollars a ton."
What Qin Tao said almost made Zhang Jinxi scream out in fright, five million dollars a ton?
Ordinary marine steel plates cost 3,000 to 5,000 RMB per ton, and warship-grade steel plates cost about 10,000 to 20,000 RMB per ton. Not counting Yinwa Steel, the most expensive high-strength steel plate they produce costs 200,000 RMB per ton.
tons, even if it is sold to a brother unit, it will not exceed 500,000 tons per ton.
What now?
Now it actually costs five million, or US dollars?
Isn't Mr. Qin too brave to ask for it?
Sure enough, when Qin Tao said this, Leske was a little nervous: "Mr. Qin, isn't the price of this kind of steel plate too expensive?"
"Expensive? Then you buy American steel, HY80. It seems that there is also HY100 now. 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 place another order."
Qin Tao shook his head: "Of course not. We will issue a quality report for the steel. We can guarantee that the steel we produce can fully meet your requirements. However, we do not provide samples, and the minimum price is ten tons."
No samples are provided, but sales start at ten tons?
If Mr. Qin said this, the other party should just stand up and leave, right? Zhang Jinxi is a little worried. If this spreads out, the reputation will not be good, right?
But we can’t discredit the group. We will have to compete in the international market in the future!
Sure enough, Lesk stood up and said: "We cannot agree to your conditions. The price is too expensive and you haven't given us samples for testing."
"Then please, after all, two thousand megapascal steel cannot be bought just anywhere."
What, two gigaPascals?
Zhang Jinxi felt his heart beating faster. After all, he had been working hard and down-to-earth since he became the head of the Mingzhou Steel Plant. He had never gone out with Qin Tao. Therefore, his understanding of Qin Tao was limited to the occasional visit.
During a meeting at the Mingzhou Shipyard, I have never heard of Qin Tao talking about trains.
Does a 2 GigaPa steel plate exist in this world?
Zhang Jinxi, a master of steelmaking, thought it was impossible.
After all, even the deck steel currently used on aircraft carriers in the United States is only 800 MPa. The one currently being studied is said to be 1,000 MPa. And the most advanced steel currently produced by their Mingzhou Steel Plant is also
At about 700 MPa, the output is still very low, and they are still continuing to study it.
Who would have thought that Mr. Qin actually said two thousand megapascals?
(I checked some information and said that we have developed 2200 MPa ourselves. It feels like bragging.)
Lesk was also moved.
Two thousand MPa of steel? His subconscious reaction was that it was impossible. But without this high-strength steel, how could the submarine being pursued at sea dive to a depth of 600 meters?
Moreover, there is obviously still room for that depth. To be able to dive to such a depth, one must either use titanium alloy or super steel.
Could it be that the steel technology here is already more advanced than that in the United States?
If it is of this level, then five million US dollars per ton is acceptable. After all, the performance is comparable to titanium alloy!
"This level of steel is also very important to our country and is absolutely not allowed to be exported. However, we are a private enterprise and must consider survival and make money, so I came here in person.
"Qin Tao said: "However, if we want to complete this business, we have to make several transfers to make it safer. If we sign an agreement with you, it will be under the name of another company."
"Mr. Qin, I would like to ask you to do a test for me. As long as I can see the test results, we are willing to buy ten tons."
Anyway, it was the employer behind the scenes who provided the money, he was just an errand boy.
Qin Tao nodded: "Of course, but please be mentally prepared. Once the deal is concluded, we will never admit that we have done such a deal."
Lesk nodded: "Okay."
Mingzhou Iron and Steel Plant, Inspection Department.
Any steel plant will set up a special inspection department to inspect various raw materials and also to test various finished products.
Of course, the testing equipment does not need to be large. For example, this yield strength testing machine. The small machine is a desktop computer with a column on the left and two clamps to clamp the object and then test it. There is an operating device and an operating device on the right.
The display interface displays various measurement data.
The equipment at the Mingzhou Steel Plant is all large. This yield strength testing machine is directly stuck on the ground. It is as tall as a person and can sandwich a desktop-sized steel plate in the middle for experiments.
Xu Zhengyang pushed the trolley, with the steel plates for testing on it, all the way to the testing machine.
"The surface of this steel plate..." Lesk looked at the shiny surface with some curiosity.
"Galvanized steel plate." Qin Tao simply introduced.
Zhang Jinxi opened his eyes wide.
What galvanized steel plate? This is obviously a titanium alloy plate, okay?
This thing was originally curved, but after being placed on the rolling machine and operated back and forth a few times, it was flattened.
Because it has been left for a long time, a layer of oxide has appeared on the surface of the board, which looks similar to a galvanized board. As for the edges, I don’t know how they were treated, but they look a bit like ordinary steel plates.
Lesk was about to step forward and touch it with his hands, but was stopped by Qin Tao: "I'm sorry, you can only look at it, not touch it."
Keske could only give up.
The steel plate was clamped up and the experiment officially began.
Lesk's eyes were fixed on the screen, the numbers on it were beating rapidly.
Seven hundred, eight hundred, one thousand!
One thousand megapascals, this is already the most advanced steel that the United States can produce!
And this special steel plate in front of us 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 are actually the most advanced in technology!
One thousand six, 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 running.
"I'm very sorry. The quality of our current batch of steel plates is not very stable." Qin Tao said, "However, this piece should be a defective product. Other steel plates, even if they do not reach 2,000 MPa, can still
Reaching 1890 MPa.”
Qin Tao was also a little embarrassed when he said this.
The cowhide is not blown, the train is not pushed, there is no steel plate with 2000 MPa, and there is no titanium alloy plate with 2000 MPa. This old Maozi’s titanium alloy plate specially used for nuclear submarines can only support the current situation.
degree.
"Forget it, the quality is unstable. You'd better not buy it. Let's just pretend that nothing happened." Qin Tao shook his head.
Who would have thought that Leske insisted at this time: "No, Mr. Qin, we are willing to buy it!"
Even if it doesn't reach two thousand megapascals, it's just over one thousand six hundred megapascals, that's still powerful enough! After they buy it back, they can study it and maybe it can promote the progress of their own steelmaking technology?
It is normal for the quality of this kind of advanced steel to be unstable. If the test really reached two thousand megapascals, then Leske really suspected that there was something wrong with the machine. Now, the fact that the data did not meet the standard made him convinced!
"No, no, we can't sell substandard steel. Wouldn't this damage our own brand?" Qin Tao continued to shake his head.
"No, no, you can sell it. Didn't we say, sign under another name? I will never come to trouble you. No matter what kind of steel we purchase, we can accept it."
"Why is this so embarrassing? Our prices will not change again. After all, the cost of this kind of steel is not low."
Zhang Jinxi was a little confused.
He had never seen such a scene before, and his outlook on life and world were completely overturned.
The test is not up to standard and the data is unqualified. This kind of fraud will be strongly despised by customers. Now, the other party actually keeps asking to buy it?
This is really Zhou Yu's fault.
"In the contract, this kind of clause must be added. If the test fails to meet the requirements, the claim will be waived." Qin Tao said.
"Yes, you can! Don't worry, 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 filing lawsuits to make money in this way. At this time, Leske immediately thought of Qin Tao's concerns and patted his chest and promised: "However, I hope
You can buy these ten tons of steel immediately."
This chapter is not finished yet, please click on the next page to continue reading the exciting content! "Of course, no problem, as long as the funds are transferred to our designated third-party account, you can take the steel away immediately. You can handle the import and export procedures yourself.
."
"Okay, I'll contact you now."
Lesk left with his men, leaving Zhang Jinxi who continued to be confused.
"Mr. Qin, where did we get this kind of steel?"
"What steel material is similar to this sample in the warehouse?" Qin Tao asked.
"We don't produce many galvanized sheets. It seems that only a batch of civil 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 let's take this batch."
"However, the yield of this batch is probably only about 200."
"Two hundred is two hundred, it's not low. They have promised that even if it does not meet the requirements, they will not make any claims. However, the appearance must be similar. Let's go and 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.
Seeing Zhang Jinxi's coquettish look, Qin Tao smiled: "What's wrong? Can't stand it on conscience? Do you know the real purpose of their coming?"
Zhang Jinxi shook his head. He just felt strange that icebreakers don't need this level of steel. What else did they say about 921A steel? Wait, could it be?
"They want to pry into our domestic R&D and production capabilities of advanced special steels by purchasing steel, and then pry into the performance of our military products." Qin Tao said: "We cannot be lenient against such opponents."
"I just received news that at present, in various large steel plants in our country, foreign customers have purchased high-strength steel." Xu Zhengyang added at the side.
Zhang Jinxi nodded, and he finally stopped hesitating: "Mr. Qin, I thought wrongly."
"Mr. Qin, after they get it, what if they find another place to test it and find that there is something wrong with this batch of steel?"
"They will definitely find a way to transport it out as soon as they get it. Don't worry."
Five million ton, ten tons equals fifty million. Two hours later, the money arrived. Then, Leske asked to see the steel, transported it to the port by truck overnight, and went through the export procedures.
