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 layout of the country has remained unchanged for hundreds of years. The city's buildings have not been updated, the railways have not even been electrified, and the power grid has not changed. They are still using the ancient method.

 For the world of capital, nothing can be done without profit, and what is available can be used as much as possible.

 The railways are old and make do. 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.

  Europe is a big place anyway, so there is no need for long-distance power transmission, 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 1989, 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 must do it yourself, because it is not available abroad.

After the success of this project, Dongfang continued its efforts to build 500 kV, 800 kV, and finally 1,000 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 13,500 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 we have to specially design a reducer suitable for 40 megawatt power, and we are not responsible for how to match it with other generators after reduction.”

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.

 Hence, even if it is matched with a reducer, it is not convenient to connect to the grid for power generation.

 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.

DiCena frowned: This means they have another expense!

what to do?

This time I will definitely lose money!

"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, Boris heard that he has been sentenced to decades, but they are just unlucky people. What old man is not greedy? It's just greed for more and greed for less.

DiCena nodded: "It seems that we have to pay more. If we spend 10 million US dollars, can we ask him to increase the price by 100 million US dollars?"

“The key is to give the money quietly so that 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 try it."

Diquena returned to the banquet hall with a sad face. The banquet here was still going on. He forced 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 1982, which needed to be tasted. This Nicola drank it all in one gulp. What a waste. He couldn't say anything, so he could only drink it. You can drink along, otherwise you may be considered dishonest.

　　After finishing the wine, Duquesne turned away the others with his eyes, and then whispered to Nicholas: "Your Excellency Nicholas, I just heard some good news. Do you want to know?"

"explain."

"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."

 Nicola shook his head: “I have no money.”

"You only need to come up with a small part of the money, and the rest can be financed through institutions, with up to ten times the leverage. For example, if you come up with $100,000, you can leverage $1 million in capital to invest in the stock market. If the stock price rises sharply, you can make millions of dollars from it. If you take out one million dollars, you can make tens of millions."

 The scariest thing about stock trading is this. 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 two hundred thousand. If I had invested one million, wouldn't I have made twenty million?

Under this kind of thinking, people who speculate 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 this." Nicholas said: "I am a duty-bound person. As long as I do my job well, that's it."

Nicolas didn’t take the bait?

Decaina 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.

 So, this business will be a normal business, without any crooked ways.

what to do?

 Comply with the contract? Then wouldn’t we have suffered a loss?

 Dicana'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 Nikola.” Nikola had a smile on his face: “I heard that your Golden Sun Automobile and Volkswagen have reached a cooperation agreement?”

"Really? I'm not sure either. I'll ask you and I'll 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?”

“Your shares of Golden Sun Auto will also rise? Okay, then I will buy some shares of Golden Sun Auto. Is the price high? Don’t be afraid of high prices, just 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, of course, Qin Tao's automobile company's stocks must 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 have 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 is not something you can see every time. It is already very difficult to have a video chat with Secretary Xu.

 “Well, what can I do?”

“Do you have AC and DC transformer equipment?”

"Yes."

“Can it switch any frequency? For example, change more than 100 Hz into 60 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 Hz. Now, what they have to solve is the last step: turning more than 100 Hz into Over sixty hertz.

"This requires first converting the alternating current of more than 100 hertz into direct current, and then turning it into an alternating current of 60 hertz through our equipment."      The frequency can be changed to any high. As long as it is converted into direct current first, there is no such thing as frequency. .

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

 “About thirty million US dollars.”

 Another 30 million, two sets of 60 million!

 If you buy a generator from Dongfang, the price is also the same, and if you buy an inverter from Dongfang, the price is also the same!

etc!

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

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

"How much?"

“The combination of generator and inverter has a package price of US$40 million, with a starting price of two sets.”

Lucas on the side frowned. This was obviously a trap for the Easterners, but it was a pity that he stepped into it!

 They planned to purchase a generator from Alstom, which cost about 10 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 30 million yuan. The total price is 40 million.

If you purchase a combination of generator and inverter from an Oriental, it will cost RMB 40 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 of them knocked on Brod's door, Brod was wearing pajamas and looked impatient.

“Hey, Duquesne, Lucas, what do you want to do? Is there anything you can’t talk about until you get to work tomorrow?”

 “We can’t wait any longer.”

"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, just tell me.”

 “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 ships. 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. 2 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$100 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 buy them from the UK. Our navy will never use Eastern goods.”

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.

Qin Tao, who is far away in the east, of course does not know the French's choice, but he knows that the French have 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.

Furthermore, it is best for the Mingzhou Group to ask for 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 completely automated. The design office will send the drawings and it will be automated like a production assembly line."

This is really not a joke. The robotic arm automatically cuts the steel plate, sends it to the bending machine, and then automatically transports it to the dock. The robotic arm places 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 the various work stations, and we still have to rely on people to transport them.”

“This is not necessarily the case. 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.”

Autonomous 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 use the road as their own parking lot...

Automatic driving cannot adapt to so many situations. However, it is already possible to take fixed routes within factories. 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%. At the same time, for warships, it can also fit inside Install bow 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 terms of 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."
