Great warships

Dongfang is known as the infrastructure madman. Various advanced construction equipment come to the fore, creating a series of impressive infrastructure projects. They build roads across mountains and rivers, build bridges hundreds of meters high in mountainous areas, drill thousands of Meters of mountain roads, building cross-sea bridges on the sea, and reclamation of land, each project makes people sigh with emotion.

Looking at the West, the pattern of hundreds of years has remained unchanged. The city's buildings have not been updated, the railways have not even been electrified, and the power grid has not changed. They still use the ancient method.

In the world of capital, if you don’t have profit, you can’t afford it early. Some things can only be used if they are made do.

The railways are aging, so make do with them. If there are occasional vehicle collisions, just get rid of them.The power grid doesn't need to be updated, and they don't have to update it.

Anyway, Europe is a big place and there is no need to transmit power over long distances, and the power loss is within an acceptable range.

It's different in the east. The electricity produced in the west has to be transported across thousands of kilometers to the east. If there is no suitable transmission mode, the electricity lost in the middle may reach half of the power generated. above.

As early as 89, the first high-voltage DC transmission project in the East, that is, the 100kV DC transmission project from the mainland to Zhoushan, was put into operation. The overhead and submarine cable hybrid DC transmission project that transmits power from the mainland to the Zhoushan Island is the first in my country. An industrial pilot project with independent scientific research, design, manufacturing and installation.

You definitely have to do it yourself, because it’s not available abroad.

After the success of this project, Dongfang continued its efforts to build 500 kV, 800 kV, and finally 1000 kV ultra-high voltage transmission projects.

AC is used for power generation, AC is used for users, and DC is used only for power transmission. This involves the conversion of AC to DC and DC to AC. The medium-voltage DC used on warships has a voltage of only 13500 volts, which is 13.5 kilovolts. Such voltage conversion is naturally a piece of cake for Eastern technology, but for the West, it is very difficult to achieve.

Now, the French are faced with a huge problem: they have a gas turbine, but they don’t have a suitable generator because it doesn’t match!
How to deal with it?

"Mr. Ntamac, can we ask you to slightly improve the generator? A generator that can match our gas turbine." Duquesne asked cautiously.

"It's impossible, the speeds don't match, we can't do it."

"Can we add a reducer halfway?"

"Then you have to design a specially designed reducer that is suitable for 40 megawatt power. Moreover, we are not responsible for how to match it with other generators after deceleration."

60 Hz alternating current has a cycle every sixty-tenth of a second. The generator must be synchronized with the power grid, which means that the error cannot exceed one-quarter of one-sixtieth of a second. The higher requirement is more than one-tenth of a second. , Only in this way can we ensure that there are wave peaks and wave crests, and wave troughs and wave troughs. If the wave crest meets the wave trough, the entire ship's power grid will be burned down.

It is already difficult for the engine to directly drive the generator to run synchronously. A reducer is added in the middle. The reduction gear has inertia and a gap. The error of this gap is definitely more than one-sixtieth of a second.

Therefore, even if it is matched with a reducer, it is not convenient to connect to the grid to generate electricity.

Alternators around the world do not dare to do this, with the exception of hydropower and wind power. These power sources are greatly affected by the outside world. In other thermal power stations, etc., the speed of the unit is strictly limited.

Duquesne frowned: This means they have another expense!
How to do?
You will definitely lose money now!
"The key to solving the problem is Mr. Nicholas. We need to get a breakthrough from him." Lucas said: "I don't believe that there are still old people who live in the mud but are not stained. Every old person is very greedy. Yes, the key is to see how much you can impress him."

Although the last bribery failed and Boris heard that he had been sentenced to decades, he was just an unlucky guy. What old man is not greedy?It's just greed for more and greed for less.

Duquesne nodded: "It seems that we have to pay more. If we spend 1000 million US dollars, can we ask him to increase the price by [-] million US dollars?"

"The key is that the money should be given quietly and no one can see it." Lucas said: "How about we ask him to buy a certain stock?"

There are many ways to give gifts. Giving them directly is the simplest and most silly. There are many ways to give gifts quietly.

"Okay." Duquesne said, "I'll give it a try."

Duquesne returned to the banquet hall with a sad face. The banquet here was still going on. He squeezed out a smile again, picked up the wine glass, and walked towards Nicholas.

"Your Excellency Nicholas, I'm very sorry. I just went out for a while. Come, let me toast you and apologize."

Nicholas smiled, raised his glass, raised his neck, and drank it all in one gulp.

Duquesne could only drink the wine in his stomach. This was Lafite from 82, which needed to be tasted. This Nicola drank it all in one gulp. What a waste. He couldn't say anything, he could only drink it. You can drink along, otherwise you may be considered dishonest.

After finishing the drink, Duquesne dismissed the others with his eyes, and then whispered to Nicholas: "Your Excellency Nicholas, I just heard some good news, do you want to know?"

"Say."

"Your Excellency Nikolay, Volkswagen and Dongfang's Golden Sun Automobile Company have reached an agreement. Volkswagen will provide capital, Dongfang will provide technology, and each will hold half of the shares. They will open a brand new electric car factory in Germany. In a few days, This project will be officially announced to the public, and by that time, Volkswagen's stock will definitely rise significantly. If you buy Volkswagen's stock now, you will be able to make a lot of money by then."

Nicholas shook his head: "I have no money."

“You only need to come up with a small amount of money, and the rest can be financed through institutions, with up to ten times the leverage. For example, if you come up with $100, you can leverage $100 million in capital to invest in the stock market. , when the stock price rises sharply, you can make millions of dollars from it, and if you take out $[-] million, you can make tens of millions."

This is the scariest thing about stock trading.If you only rely on your own funds to trade stocks, the most extreme situation is to lose all your principal. However, the essence of stock trading and gamblers are the same. After making a small profit, you will not be satisfied with your principal. I invested One hundred thousand, and I only made 20. If I had invested 100 million, wouldn’t I have made 2000 million?
Under this kind of thinking, people who trade in stocks will borrow money, increase leverage, and even use usury. In the end, their dreams of getting rich are shattered and they are still in debt.

"I don't have money, and I don't do these things." Nicholas said: "I am a duty-bound person. I just need to do my job well."

Nicholas didn't take the bait?

Duquesne was unwilling to give in: "If you don't have the principal, we can lend you the principal. After you make money, you only need to repay our principal."

Nicholas continued to shake his head: "No, I'm here for the Navy's amphibious assault ship. I can't have any financial dealings with you. Otherwise, when I go back, I will end up like Boris."

Duquesne suddenly reacted: No bribery method can impress His Excellency Nicholas. This is not a question of the amount of money, but a question of position.

When the tender was first held, Boris was beaten because he accepted a bribe. Similarly, there will be many eyes watching. If Nikolay accepted a bribe from the French, he would also be found out, and Nikolai would be with him. Boris is going to die.

Therefore, this business will be a normal business, and there will be no evil ways in it.

How to do?
Completely follow the contract?Then wouldn’t we have suffered a loss?
Duquesne's face looked a little ugly.

After the meeting ended, Nicholas walked out of the banquet hall with brisk steps and went straight to the airport. He was not even willing to stay in France for a while. After returning to Moscow, he picked up the phone and dialed the familiar number. .

"Qin, this is Nikolai." Nikolai said with a smile on his face: "I heard that your Golden Sun Motors and Volkswagen have reached a cooperation agreement?"

"Really? I'm not sure either. I'll ask you and call you back later."

Nicholas had a sneer on his face.

A few minutes later, the call came back.

"Qin, how is the situation? What, is this true? Will Volkswagen's stock price rise?"

"Will your Golden Sun Auto's stock rise? Okay, then I'll buy some Golden Sun Auto's stock. Is the price high? Don't be afraid of the high price. Buy a few million shares first!"

A gentleman loves money and gets it wisely. Nikola will not ask for French money. It is too dangerous. However, Qin Tao's automobile company's stocks must of course be bought to support it.

Putting down the phone, he looked at Zaitsev who was driving: "After you go back, set up an investment company in the name of your brother, and then buy some shares of Golden Sun Auto from the East. It will be completed within three days and sold out in a month. .”

"Yes." Zaitsev nodded.

France.

After sending Nicholas away, Duquesne told Lucas the matter. Lucas' face was also extremely ugly: "It seems that I can only ask the Easterners."

He didn't hold out any hope. After all, the price charged by the Easterners would definitely be high.

"Secretary Xu, it's nice to meet you." Ducaina turned on the computer and logged on to ICQ. He saw a familiar person's profile lighted up. He quickly started the video chat and showed a flattering smile.

Mr. Qin can't be seen every time. It's not easy to have a video chat with Secretary Xu.

"Well, what can I do?"

"Do you have AC and DC transformer equipment?"

"Yes."

"Can any frequency be switched? For example, more than 100 Hz can be changed into [-] Hz."

If the generator remains unchanged, then driven by the UGT40000 gas turbine, the speed will increase, and the frequency will also increase, and it will become more than 100 hertz. Now, what they have to solve is the last step: turning more than 100 hertz into more than 60 hertz.

"This requires converting alternating current of more than 100 hertz into direct current, and then converting it into alternating current of [-] hertz through our equipment." The frequency can be changed to any high. As long as it is converted to direct current first, there is no such thing as frequency.

"How much does such a piece of equipment cost? Forty megawatts."

"About $3000 million."

Another 3000 million, two sets of 6000 million!
If you buy a generator from the East, the price is also the same, and if you buy an inverter from the East, the price is also the same!
and many more!

Although Ducaina knew that he had fallen into a trap, he still held on to some illusions. He thought of something and quickly said: "If I purchase a generator from you, can I get this kind of inverter as a gift?"

"Of course not. A generator is a generator and an inverter is an inverter. However, if you purchase them in a package, I can give you a preferential price."

"how much is it?"

"The package price of the combination of generator and frequency converter is US$4000 million, with a starting price of two sets."

Lucas frowned on the side. This was obviously a trap for the Easterners, but it was a pity that he stepped in!
They planned to purchase a generator from Alstom, which cost about 1000 million yuan per unit, but it couldn't be used. They had to purchase this kind of power-swapping equipment. The Oriental offered a price of 3000 million yuan.The total price is 4000 million.

If you purchase a combination of generator and inverter from an Oriental, it will cost 4000 million. In this case, how should you choose?
It must be from the East. What if Alstom's generator doesn't match it?At that time, it will cost more, so it is better to purchase the whole set from the East.

The price is definitely overpriced and the construction will be a loss. What should we do next?
"We need to find Brod." Duquesne said: "They asked us to accept this contract at a very low profit. Now we are about to lose money, and we will lose a lot of money. We must find someone They’re going to fill this hole for us!”

At first, considering that the profit was too low and the risk was too high, they originally did not plan to take on this business, but Brode kept insisting, so they could only bite the bullet and accept it. Now that it has reached this point, they must find DCNS. Got it!
It was already ten o'clock in the evening. When the two knocked on Brod's door, Brod was wearing pajamas and looked impatient.

"Hey, Duquesne, Lucas, what do you want to do? Is there anything we can't talk about until we get to work tomorrow?"

"We can't wait."

"why?"

Of course it’s because we can’t sleep, we can’t sleep, and we can’t let you sleep!

Duquesne said: "Let us go in, we have important things."

"You can't go in!" Brod wanted to stop him, but he didn't. Duquesne had already walked in.

The sofa was messy, and a blonde girl was lying there, lazily. When she saw a few people coming in, she wrapped herself in a blanket: "I'm going to the bedroom first."

The blanket covered the front but not the back, leaving an unobstructed view.

"Is she reliable?" Duquesne asked.

"The people in our bureau are very reliable, you name it."

"Okay." Duquesne said the matter again.

"In other words, you didn't think well at the time and missed the generator?"

"No, this has nothing to do with us. It's all because you pushed too hard." Duquesne's expression changed. This guy actually wanted to pass the blame?We must not let him throw the blame over.

"Then what are you going to do?"

"We need the government to provide us with this money. After all, it was originally meant to provide jobs for a large number of boat workers."

"That's impossible. The government's funds are also very tight. It can't even raise funds for a second aircraft carrier. How can it fill this hole for you? You have to find a way for yourself."

"If we had a way, we wouldn't come to you. Also, don't expect Da Mao to increase the budget, that's impossible."

"If they don't increase their budget, they won't be able to get our boats. This is a necessary price increase."

"Then our credibility will be completely lost." Duquesne said: "Are you sure you want to do this?"

"It's a pity that we have already imported two gas turbines. Otherwise, we can cancel this business." Lucas sighed, and then thought of something: "If our aircraft carrier No. [-] is to start construction, this The two gas turbines can also be reserved for the aircraft carrier, but we will not do this business!"

"The start of aircraft carrier construction is far away, so there's no need to wait," Brod said.

In fact, if they stop now, that would be the most suitable choice. However, the two gas turbines purchased for US$[-] million must have a purpose, and Mingzhou Group will never accept returns.

"Moreover, even if our aircraft carrier starts construction, if we want to purchase gas turbines, we can still buy them from the United Kingdom. Our navy will never use Eastern products."

The British will not allow their gas turbines to be used on Da Mao's warships, but there is no problem if they are used on France's own aircraft carriers. Although British gas turbines are somewhat difficult to produce, in terms of technical indicators, British gas turbines are still very high.

For example, the fuel consumption rate of British gas turbines is very low, which is already comparable to that of diesel engines. Their lifespan is also very long, and their bodies are even more compact.The East only solves the problem of availability, while the British want to solve the problem of performance. They will definitely not use it if it has poor performance.

In this way, the ball kicks around and comes back.

They have no other choice!

"Didn't Da Mao repeatedly increase funding when it refitted Asan's aircraft carrier? We were forced to increase funding for Da Mao, and they would accept it." Broder continued: "By then, they have invested a large amount of money and will not increase the budget. , we will not deliver the ship to them. The warship is in our hands, so what should we be afraid of? You go and build it first."

"Then we don't have the budget to purchase additional generators and frequency converters." Ducaina said: "You have to find a way to advance this money to us, and we will pay you back after Da Mao increases the budget."

"Okay, let's coordinate with the bank and give you a loan, interest-free." Brod said.

Of course, Qin Tao, who was far away in the east, didn't know the French's choice, but he knew that the French had no choice at all. As for wanting to default on the bill and use warships to blackmail Lao Maozi to increase the price?What a joke!Are Lao Maozi and Ah San the same order of magnitude?This is simply seeking skin from a tiger, and I will teach them a lesson.

Moreover, it is best for the Mingzhou Group that the French demand a price increase and threaten with warships, so that Lao Maozi can know who is the most reliable.

Qin Tao has no plans to go out recently. The 003 nuclear-powered aircraft carrier is also a brand new project for Qin Tao. He has never built one in his previous life. Therefore, he has to concentrate on the construction of this aircraft carrier and wear safety helmets every day. Hat, I went to inspect the shipyard with Makarov, feeling full of accomplishment.

The welding arm of the automatic welding machine was moving slowly, and sparks from the arc were flying. Makarov said with emotion: "Mr. Qin, we only thought that as we continue to spread the pie, there will be less and less workers, and the technical school will not be able to train them enough." We have enough talents, but I didn’t expect that the automated equipment would greatly save workers’ labor and improve efficiency.”

"Of course. Our shipbuilding industry was originally a labor-intensive industry, but now it has to become a technology-based enterprise. Even in the future, it will be fully automated. The design office will send the drawings and it will be automated like a production assembly line."

This is really no joke. The robotic arm automatically cuts the steel plate, sends it to the bending machine, and then automatically transports it to the slipway. The robotic arm puts the steel plate in the right position and automatically welds it. It can really achieve full automation.

"Transportation is a big problem." Makarov said: "There is a long distance between each workstation, and we still have to rely on people to transport it."

"This is not necessarily true. We have electric trucks that can walk on their own in the shipyard in the future." Qin Tao said, "It doesn't necessarily have to rely on people."

"Can the truck still walk on its own?"

"Of course, it will come true in the future. By then, trucks won't even need a cab."

Self-driving technology requires very high requirements. At the beginning, it will definitely not be driven on the road outside. After all, the road conditions are too complicated, including pedestrians who run red lights, speeding vehicles, and people who treat the road as their own parking lot...

Autonomous driving cannot adapt to so many situations. However, within the factory area, it is already possible to take fixed routes. Even the vehicles that dump containers in some terminals have removed their cabs and are completely dispatched by the control center.

Of course, our own factory can be built in this way, and it should appear within ten years.

"The bulbous bow of our warship is ready." Nicholas and Qin Tao came to the dock while talking. They could see that the lower part of the first segment of the ship's bow was ready. There is a big nose at the beginning.

The existence of the bulbous bow is mainly to reduce the resistance of traveling waves, increase the speed of the ship, and reduce fuel consumption. Such a big nose can reduce fuel consumption by at least 5.00%. At the same time, for warships, it can also install a boat inside. First sonar.

“Our previous aircraft carrier bulbous bows used a spherical structure, but the drag reduction effect was not good. Now, our bulbous bows use a spindle-shaped bulbous bow, which is completely designed for drag reduction and has better high-speed performance. .”

In appearance, it looks like a big nose that has been flattened.

"However, the processing of this shape is more difficult. We have a three-dimensional CNC bending machine that can bend it into the corresponding shape, but if not, it would be too difficult. Asan's aircraft carrier does not have this technology. Just don’t add a bulbous bow.”

Hearing Makarov's words, Qin Tao smiled: "Really? However, there is nothing that Asan can't do."
