Great warships

Chapter 207

Northern Fleet!

During the period of Tsarist Russia, it was only a small-scale Arctic Ocean Fleet. After the establishment of the Red Empire, the Arctic Ocean Fleet was rapidly expanded and renamed the Red Navy Northern Fleet, and gradually expanded.

By the time the Red Empire collapsed, the Northern Fleet had already become the largest and most powerful naval fleet among Lao Maozi and Lao Maozi's five fleets!
How big is it?Just look at a set of data.The Northern Fleet has two-thirds of Lao Maozi's nuclear submarines and more than half of its surface ships. Moreover, after various advanced warships are manufactured, they will be equipped with the Northern Fleet first!

Therefore, up to now, the Northern Fleet has retired a lot of warships that have reached their end of life, but not many of them can be disposed of. Most of them have entered the warship cemetery, that is, an abandoned dock. Sun and rain.

After the collapse of the Red Empire, the size of the Northern Fleet shrank rapidly, and more warships had to be decommissioned. There were even more abandoned warships in Lao Maozi's warship cemetery.

Therefore, if we can catch up with the Northern Fleet line, then Mingzhou Shipyard will have more ship breaking business in the future, and even a specially opened ship breaking yard will be enough. As for the benefits of ship breaking, there will be more Well, as long as you do something, you can still get back more good things. After the collapse of the empire, the degree of chaos is unimaginable. Even some big killers can be obtained from the bottom officers guarding the warship cemetery. The lower you are, the more courageous you are.

At this time, Qin Tao was very excited when he heard Boris say this.

The Pacific Fleet has Nikolai, and the Northern Fleet has Boris' relationship. In the future, my career will be improved to a higher level!
Although Boris is an ambitious man, he still wants to express his gratitude to the person who saved his daughter twice. Moreover, Qin Tao also said that he also has connections in China, and he may be able to use Qin Tao in the future.

Now, Boris was very happy to see Qin Tao, so he also smiled: "Qin, I hope we can have a happy cooperation in the future."

"Well, I will dump enough light industrial products. Mr. Boris, you can also get a share of it. By the way, have you dumped an off-road vehicle?" Qin Tao suddenly thought of something.

In the past, Qin Tao had already promised the navy to help them get a batch of off-road vehicles back. However, Lao Maozi's automobile industry is not developed, so it is okay to go back and transport cars. There is no such off-road vehicle for the time being. Get it right.

At this time, I happened to meet Boris, who was specialized in the car business.

"Mercedes-Benz has a G-class off-road vehicle, but it's very expensive. I'm afraid it's unacceptable in your country. There is also Mitsubishi's Pajero, which is also very popular in Europe." Boris is indeed an expert, and he immediately introduced it.

Qin Tao nodded: "Well, a few G-class cars can come, mainly Pajero, I need a batch, I can get it to the port of the Northern Fleet, put it on an abandoned ship, and we will take it back directly."

Hearing what Qin Tao said, Boris' eyes sparkled: "You don't need to declare at the customs? Qin, you are indeed a powerful person. In the future, we may have many opportunities to cooperate."

In his eyes, he already regarded Qin Tao as a smuggler.

Qin Tao smiled, but did not answer. There is an essential difference between himself and those people. He is not here to make money, but to help the construction of the navy.The army needs a large number of off-road vehicles, neither 212 nor Cherokee, and the most popular in the army is Pajero.

However, the army has no money, and imports cost precious foreign exchange. Therefore, Qin Tao can only help the army find a way, and get a batch of them back for the army. For the sake of the country and the army, he is very noble. .

As for the Mercedes-Benz G-Class, it is good for Qin Tao to use it for himself or give it away as a gift.

Qin Tao made a decision.

Boris had the same smile on his face, as if to say, we are in the same business.

"At present, our country is still in chaos. I will pay attention to this matter. I will contact you when there is a result." Boris said.

When the two of them said this, it was supposed to be almost over.Qin Tao obviously didn't intend to let Boris go. This is a good opportunity to see if he can get some information from Boris.

"Yes, your country is really in chaos, but you will definitely settle down in the future, and you will also live a free life like the West, which is the same as the main purpose of the Freedom News you founded." Qin Tao said.

Boris nodded: "Yes, we believe that the light will come soon."

"It's just that it's not easy to distribute the country's property equally to individuals, right?" Qin Tao said to Boris.

Boris nodded: "Yeah, everyone is having a headache right now."

The so-called big guys are of course those who are united around the conspirators. They are busy seizing power and thinking about the future. It is not so easy to divide up the wealth of the huge empire. You can't get it directly in your own hands, it's too ugly to eat.

"I have an idea." Seeing Boris' perplexed look, Qin Tao said slowly.

"any solution?"

Boris' eyes widened.

So, in this ordinary German hotel room, in this silent late night, Qin Tao helped Lao Maozi make a plan.

Because of his suggestion, he completely won the goodwill of Boris and more people, so that in the next few years, he would collect trash everywhere in the old man's land with ease.

"The wealth of a country must be evenly distributed, including so many factories, enterprises, mines, etc., which cannot be separated." Qin Tao said: "So, we can only first evaluate and identify these countries. The specific value of wealth, and then, calculate the specific value of all state-owned assets, and then divide them equally according to the number of people in the country, and give each person a bond."

First evaluate, then average, and finally send to everyone's hands. In this way, even if all the wealth is divided equally, it is fair and reasonable.

Boris frowned, splitting a bond, isn't that just a piece of waste paper?

Sure enough, Boris, a car dealer, is very familiar with economics.

"However, these enterprises must be contracted by someone to operate them. Then, those who are capable and rich can buy this bond from ordinary people, so that they can obtain the shares of a certain enterprise and complete the privatization process. For example, if you are engaged in automobiles, you can use your own funds to purchase the average bonds of the automobile factory, and then obtain the shares of the automobile factory.”

"But, what's the point?" Boris finally asked the key question: "That is equivalent to buying a car factory with the money I have accumulated over the years?"

Isn't this equivalent to giving his money to ordinary people, how can he be willing?To paraphrase He Shen's famous saying, it's a crime to distribute the vain money to the poor!
Seeing Boris' unwilling expression, Qin Tao smiled: "Let me give you an example, take the Gorky Automobile Factory as an example."

Boris listened carefully.

"Because you were originally engaged in importing cars, you can invite European auto experts to give an appraisal of Gorky's car, for example, the price is 20 billion." Qin Tao is very casual, as if chatting with family, and doesn't care about this kind of thing at all. The operation will make Da Mao miserable after the collapse.

Anyway, if Qin Tao doesn't make suggestions, others will do the same. Now he proposes that the old Maozi's senior management must always think of him.

"Then, at the price of 20 billion, it was distributed to the people. After all the distribution is over and everything is settled, you can ask an auto expert to evaluate it. Then, the auto expert will say, no, I was wrong at the beginning, at most Worth [-] million."

Boris' eyes immediately lit up, he already understood the rules of this game!

Boris' breathing became short of breath, he looked at Qin Tao, and took over the words: "In this case, I will definitely not spend 20 billion to buy this kind of bond, I will spend at most [-] million, or even less, because those Bonds in the hands of ordinary people are just waste paper, and if they want to exchange money, they have to come to me, and I can buy it at a quarter of the face price, or even lower, and those people have to sell it!"

Genius, definitely a genius idea!He knew that his daughter was right, this Qin was too powerful!To be able to do business everywhere in the Red Empire is definitely a genius.

"I'll go back tomorrow and tell everyone about your suggestion," Boris said.

"By the way, don't say my name, I don't want to..."

"No, you made the suggestion, and I can't take your credit." Boris was very firm at this time, just like Qin Tao didn't want all the compensation just now.

"Qin, what are you afraid of? I will tell everyone about you, so that it will be convenient for you to do business in the Soviet Union in the future."

"Well, can I use my identity as a reporter?" Qin Tao asked.

What are you afraid of?Afraid of being scolded!This idea has cheated so many people of Lao Maozi, if he knew what Qin Tao did, why not make a scarecrow in the style of Lao Maozi and stab him with a fork every day?
"Okay, Qin, I can make your identity seamless for you. In the future, you can use this identity to act in our Soviet land, and Zhao."

Nima, this guy is really awesome, Qin Tao is secretly happy in his heart, if he has such an identity, it will be too convenient to move around in the future!

Therefore, Qin Tao had to reciprocate. He continued to suggest to Boris: "In the future, you can establish an All-Russian Automobile Union and monopolize it to bring benefits."

Boris listened attentively.

In the middle of the night, Boris finally walked out of the room. Zhao Ling was so sleepy that she couldn't keep her eyes open. After returning, she fell asleep.

When I got up the next day, I went shopping with Vitalia, of course, because all my personal belongings fell into the sea, so I had to buy some. Until that night, Christian called and Helmut sat in the evening. After returning from the plane, Christian will take Qin Tao and the others to Lübeck Engineering Design Institute tomorrow.

This morning, when Qin Tao and his group arrived at their destination, they discovered that this design office was actually established in a university!

The surrounding environment is very elegant, the buildings are very simple, and it is already late autumn, so the leaves of the big trees on both sides of the road have fallen down, forming a thick layer on the ground, but there is no cleaner to sweep, so people like this Walking on it, it seems full of emotion.

An ordinary-looking small building turned out to be a German submarine design agency. It was unbelievable. Helmut stood at the door of the building and watched the car drive over.

"I heard from Christian that you came here on a private yacht, and there was a collision at sea. It's really bad news, but fortunately, you were not injured, thank God. By the way, you also went to see it in the submarine, right? How do you feel?"

Thank God?When we fell into the water, we didn't see a guy called God come swimming to save us.

Qin Tao felt a little slanderous in his heart, but he could only nod when he heard what Helmut said: "Yes, we escaped from death, but after we went up, we just dried our clothes in the power cabin at the back. I was in a bad mood at the time, so where else can I see the interior of the cabin. My friend, if you say that, are you going to take us up to have a look, anyway, it’s just an export-oriented submarine.”

Helmut nodded: "Yes."

Qin Tao is really right. The 209 submarine is a submarine designed and built by the Germans in the 70s. It has been exported to many countries, and some countries are even allowed to build it themselves. The German Navy has no equipment, so it is not at all. What a secret.

Now that the words have been said to this extent, it seems that there is nothing wrong with taking it to take a look.

Christian didn't object either. The two of them unified their opinions in this way. It would be no problem for Qin Tao to go to 209 for inspection, but he didn't know how those Smectas would feel.

It is estimated that the ship that has been built and is allowed to visit is the one in Kimchi Country.

"Let's go, let's go to the meeting room." Helmut said: "Qin, your plan is really a genius idea. I passed your plan back that night. We have a design team here , specifically study the plan you mentioned, and preliminarily think it is feasible.”

Sure enough, the lithium battery plan fooled them!
Qin Tao took Zhao Ling and Vitalia into the meeting room, and sure enough, there were already several people waiting there.

"This is the person in charge of our submarine power system design department. Stephen, this is Miller, an expert in our submarine power supply design." Helmut introduced several people to Qin Tao. It seems that what Qin Tao said , really moved them.

In fact, the current lithium battery has just appeared, and its performance cannot be compared with that of later generations of lithium batteries. The current 18650 battery has a capacity of only 800 mAh, which is really worthless compared to the capacity of 3000 mAh in later generations. carry.

But even that has one huge advantage over batteries: weight.

Ordinary storage batteries are called lead-acid batteries, which are made by soaking pure lead and lead dioxide in dilute sulfuric acid solution. The density of these two types is not small, so lead-acid batteries are very heavy. (You can try to move the lead-acid battery on the electric car.)
In order to have a long enough battery life underwater, diesel-electric submarines use a large number of lead-acid batteries, which are similar to the size of a car starter battery. There are at least hundreds or even thousands of dollars, all of which are stuffed in the bottom of the submarine. Down below, this allows the center of gravity to be lowered to facilitate the balance of the submarine. Therefore, despite the round appearance of the submarine, there is even a conning tower on it, but the submarine will never overturn, because the heaviest battery is pressed underneath. !
If 18650 batteries are used instead of lead-acid batteries, their submarines will save considerable weight!

Inserting an 18650 battery of the same volume saves at least two-thirds of the weight, and at least half the capacity.

So, they were really tempted, but after careful study, they found a big problem: how to stuff it in?
A lead-acid battery for submarines is about the size of a brick of the Great Wall, so it can be easily arranged and combined. However, a single 18650 battery is about the same size as a human finger. ?

So, after sitting down, Miller couldn't wait to ask: "Excuse me, how do we install these batteries?"

"Series and parallel connection." Qin Tao answered very simply: "These batteries can be put together vertically, for example, fifty or one hundred batteries as a group, to make a rectangular battery box, and then put these battery boxes put together."

How to install, needless to say?It must be series and parallel.

"There will be a big problem here. If the consistency of these batteries is not good enough and the internal resistance is different, after series-parallel connection, there may be accidents during charging and discharging. Some batteries may be overcharged and overheated. , and even catch fire and explode.”

Although lead-acid batteries are heavy, they are safe anyway.

"This requires a complete battery management system." Qin Tao said: "To monitor the charging and discharging of each battery, safety devices are also required. For example, each battery must be welded with a fuse. Once charging and discharging If the current is too high, it will blow."

This is the same as the electric vehicles of later generations. If you want to be able to use them stably, the most important thing is the management system of the battery.

But just thinking about the level of complexity involved makes one's scalp tingle.

Qin Tao looked at the people present. This system has to wait for the people who make electric cars to mature it. But now, it's okay to publicize it to them.

"The development of lead-acid batteries has reached the limit so far. It is difficult to continue to improve performance. However, lithium batteries are different. This kind of battery has just begun to be commercialized. In the future, this kind of battery will gradually improve and develop. , The capacity will be doubled several times, so it must be very promising." Qin Tao said: "It's just that I'm not an expert in this field, so I can only think of so much."

Qin Tao's current identity is just an ordinary reporter, and he is not a specialized battery expert, so there is no need to answer too many questions. If he answered too many questions, wouldn't it appear that he is too powerful?
"Can you talk about your 209 submarine? I plan to write a special report, and now I just want to interview you." Qin Tao came here to obtain their information, so now, he will soon start to turn against customers.

"What do you want to know?" Helmut asked.

"You have always used a single-hull structure. This structure will be very dangerous when encountering accidents such as collisions. What methods do you use to ensure the reliability of the submarine during collisions?" Qin Tao asked Helmut Said: "Let's start with the incident where we were hit. If we were not on a small yacht, but a large warship of several thousand tons, such as the Hyundai class, I am afraid that the 209 submarine would not be able to drive back. gone."

The question Qin Tao raised was very sharp, and it was also the first question that almost all submarine designers would encounter.

Lao Maozi’s submarines are all double-hulled, with pressure-resistant hulls inside, personnel and the like inside, and a layer of non-pressure-resistant hulls on the outside, so that once an impact occurs, the outer shell will be damaged, even if it is hit by a torpedo The attack is also that the outer shell is attacked first, and the inside is likely to survive.

After entering the Cold War period, Western submarines used a single shell, that is, an outer shell. In this way, with the same weaponry and equipment, Western submarines have smaller displacement and better silent performance.

"I have read a lot of information, saying that the Western rolling and welding technology is superb, and the pressure shell can be made to have a large diameter, so it is a single shell, especially the large-scale plate rolling machine from Sweden is used, while the Soviet Union's technology is backward. It is impossible to weld a large-diameter pressure-resistant shell, so a small-diameter pressure-resistant shell has to be made, and a non-pressure-resistant shell is wrapped outside, what do you think?"

There are always some people who will belittle the Soviet Union's military technology, saying that the Soviet Union can't make a pressure-resistant shell with a large diameter. Qin Tao doesn't think so. Lao Maozi's double-shell structure is to push open the Arctic ice cover to launch missiles. , If you say that the old man is not good at precision machining, what's the problem with welding a submarine pressure hull?

"The submarine we built is not for collision." Helmut said with some embarrassment.

What should I do if I hit it?It depends on your luck. If you are lucky, you will go back to accept the trial of the military court. If you are not lucky, you will be buried in the sea directly.

This is the same as some people drive a car. The car is used for driving, not for hitting. The problem is, how can you not get your shoes wet when you often walk by the river, and the submarine is the same. What if it really hits?
Ships on the sea, reefs on the seabed, etc.

"What if we bump into each other?" Qin Tao continued to ask.

"Then... do you have any good ideas?"

"You said, would it be better if a single-hull structure was made in the middle of the submarine and double-hulls were made in the front and rear?"

Helmut's eyes lit up, it was indeed a plan!The person in front of him really has a very open mind.

"How is this designed?" Some people also began to doubt.

The single hull is cheap and saves displacement, but it is not crashworthy. The front and rear are made into a double hull structure, thus becoming a single and double hull hybrid structure, which is definitely a revolution in submarine technology.

But how?
"I just had such an idea just now. How about you take out the large-scale design drawings of the 209 submarine and let us study it together?"

Helmut frowned, hesitated for a moment, then nodded: "Okay, let's study together!"
