Since power plants and users are not in the same place, power needs to be transported there, and transmission lines also consume energy, so the transmission company must choose the most appropriate transmission method.
Conventional AC power for civilian use has two types: 110 volts and 220 volts. However, if this voltage is also used for power transmission, it would be too wasteful. A large amount of energy will be consumed on the transmission lines, and the main loss is heat.
Heating is related to current. The greater the current, the more heat is generated. When the transmitted electric power remains unchanged, the higher the voltage, the smaller the current. Therefore, with the development of technology, the transmission voltage is getting higher and higher. Generally speaking, if
If you want to transmit electrical energy to a distance of 800 kilometers, you need a voltage of 110 kV to 330 kV, which is also the highest transmission voltage currently available in the West.
For the West, this technology is enough, but for the East, it is far from enough. After all, the energy is in the west and the users are in the east. The transportation from west to east often takes two to three thousand kilometers.
This requires ultra-high voltage transmission technology. The transmission voltage of more than 800 kilovolts is eight times higher than the voltage of 110 kilovolts, the current is reduced to one-eighth of the original, and the transmission loss is reduced to the original
Sixty-four.
However, the design and manufacture of UHV transmission equipment is difficult. After all, with such a high voltage, insulation is a big problem. Dongfang has perfectly solved these problems and has become the standard setter in this field.
How awesome is it? In later generations, the United States will need to import power equipment from the East. For example, in 2017, the amount of imports reached 21.8 billion U.S. dollars. Americans have to use what they import. Therefore, everyone in the power company has to learn Chinese, because
Equipment exported by Dongfang never provides English instructions!
The Americans are very bitter, but there is nothing they can do about it. After all, the technical standards are Eastern.
The equipment produced by Dongfang is not only used in UHV power transmission, but many ultra-high-power components can also be used on warships and catapults. Without these components, it would be impossible to build advanced electromagnetic catapults!
Dongfang can be the first to complete the practical use of electromagnetic catapults because Dongfang has this technical foundation. Other countries are not envious of it, because they do not have such a foundation at all!
At this time, Alex felt a sense of despair after hearing Raja's words.
"In other words, we can't build an electromagnetic catapult at all?"
"Yes, but if we can't build it, France may be able to build it. Maybe we can see how the French solve the problem." Raja said: "Of course, if there is no other way, we may still be able to build it.
Find ways to purchase from the East through Da Mao.”
"No, no, we will never purchase from the East. This is our bottom line!" Alex's voice almost roared. Are you kidding, purchasing from the East? Ah San will never spend his money.
On the Orientals!
It seems that we can only rely on the French.
Is France OK?
France, TT company.
"How about it? Such an important project has been handed over to your company. We don't want to hear bad news. We just want to know when the prototype of the electromagnetic catapult can be handed over to us." Chapelon said: "Our navy's first prototype
The two nuclear-powered aircraft carriers are just waiting for the good news about the electromagnetic catapult."
France is anxious. There are aircraft carriers coming one after another from the East. That's okay. The United Kingdom next door has two, which is tolerable. However, in Africa and the Middle East, aircraft carriers are also starting to appear one after another. If France
If the navy doesn't work hard, it may be surpassed by a small African country!
The 40,000-ton Charles de Gaulle is definitely not enough. They also need a new aircraft carrier. This aircraft carrier must be able to compete with the Eastern 003 aircraft carrier!
Relevant departments have begun demonstrations. It has a full load displacement of more than 80,000 tons, a total length of 304 meters, and a width of 90 meters. It has a rear island. Various advanced phased array radars must be installed on the island, and a nuclear power system must be used.
But this nuclear power system cannot be too useless. The aircraft carrier must reach a speed of thirty knots.
The aircraft carrier as a whole is almost comparable to the aircraft carriers in the East.
These are all hard targets, and at the same time, the electromagnetic catapult is also a hard target!
Anyway, France does not have steam catapult technology at all, and the Charles de Gaulle was imported from the United States at a large cost. Once this electromagnetic catapult technology breaks through, they will no longer be controlled by others.
However, when faced with his questions, the engineers of TT Company all lowered their heads, looking a little embarrassed.
"What's wrong, everyone? Do you still have any questions?" Chapelon said: "We have obtained most of the drawings, and the remaining drawings can be supplemented. Our French technology is world-class, is it not as good as Asan?"
"Even if we get all the drawings, we can't make them. There are some special parts, especially high-power parts, that we in the West can't produce at all."
"How is it possible? There are still parts that we can't produce?"
"Yes, only the East in the world can produce it, we..."
"Then let's buy it from the East!" Chapelon said: "We are not short of money!"
In order to develop electromagnetic catapults, they are willing to spend more money. Compared with the harvest, no matter how much they pay, it is worth it!
"Orientals don't sell it."
"Not selling? Why?"
"Because the technology is too advanced, it is a prohibited product for export."
Even if the French wanted to buy it, they couldn’t!
"Yes, it's quite funny. There are many technologies and products they prohibit exporting, such as their nuclear power plants."
This is even more ironic. Seventy percent of France's electricity comes from nuclear power. France's nuclear power technology is the most advanced. In the 1990s, Dongfang exported its technology to build the Daya Bay Nuclear Power Station. Now, Dongfang's nuclear power technology
It has left the whole world behind and reached world-class status.
Just hearing the name of a high-temperature gas-cooled nuclear reactor, you can feel how advanced it is! This is the world's first commercial fourth-generation nuclear reactor. Orientals actually list this reactor as a technology prohibited from export.
Here, can this thing still be used on an aircraft carrier?
"Huh, if they can do it, we can do it too!" Chapelon said: "I don't believe our technical staff don't have the strength."
"Of course there is, but we have estimated that it will cost about 500 million euros to make these parts."
Chapelon felt his head grow bigger at that moment. No matter what they do, they have to spend money, and they have to spend a lot of money! They are not afraid of spending money, but is this necessary?
"Can we find a way to purchase from Orientals through Lao Maozi? We can't buy it, but Lao Maozi can."
"Then we need to contact Tomsk State University."
The technology was spread from there, which means that there is a connection with the Orientals. If you want to buy things now, you must go there.
After receiving the instruction, Messager quickly came to Tomsk and met Volkov, the dean of the School of Mechanical and Electrical Engineering.
"Mr. Volkov, our TT company is currently developing some projects that require high-power components. I wonder if you have suitable parts to sell to us."
"Of course, our Da Mao technology is very advanced. As long as you ask for it, we can make it."
"Okay, this is what we need."
Volkov took the document, opened the first page, and his face darkened. He flipped through three pages and then closed the document: "What are these parts used for?"
"It is used in an advanced motor customized by our company for customers."
"Linear motor? Or super powerful one?"
"You can say that, however, these are customer secrets and we are not in a position to disclose them," Messager said. "We just want to know if you can provide this component."
"Of course you can, but these components are very expensive. All the parts on your document cost $200 million."
This time it was Messag's turn to be surprised. He almost jumped up from his chair: "What, two hundred million? You are too..."
Isn’t it too dark? How can you use so much money? You purchase it from the East, the maximum is 20 million, and when it comes to you, it becomes 200 million, and you can make ten times the profit by reselling it?
"Isn't it too easy for us? Not to mention anything else, just for this super power inductor component, we need to invest huge funds in research and development. We failed thousands of times before we succeeded. Isn't this money?"
"Also, for this IGBT, the power you need is a hundred times that of the commonly used parts on the market, but the heat cannot exceed the standard. If you make a hundred of this thing, maybe only one will be qualified. You have to spend a lot of money.
The money does not belong to this one, but to hundreds including this one."
"Look at this again..."
What Volkov said was reasonable, and Messag couldn't object. After all, they really couldn't produce these things. Now they need to invest at least 500 million in research and development, and they only spend 200 million, which is still acceptable.
"Okay, then I will go back to the customer to discuss it. If the customer agrees, we will pay half of the deposit first, and then pay the other half after we get the goods."
"sure."
After seeing Mesag off, Volkov excitedly picked up the phone and called Nikolai, and then Nikolai excitedly called Qin Tao via video call.
"Mr. Qin, as expected, the French also came to us and wanted to buy parts. We asked for 200 million, and they accepted it. We made a lot of money again!"
Qin Tao's smiling face appeared on the video: "This is just the beginning. Next, Ah San will come to you and we can make another 200 million! Congratulations to you, Nicholas."
"Qin, these are all your contributions, I have to thank you! On behalf of the navy, I thank you!"
"That's right. We are all friends. It's too foreign to say this. By the way, in order to better fool them, your navy should also introduce its aircraft carrier project."
"I know, we'll hold a press conference right away."
At the end of the video call, Qin Tao showed a smile on his face: "One trick can be eaten all over the world. From now on, our Mingzhou Group will rely on world-leading technology to make money!"
Xu Zhengyang on the side was a little worried: "Mr. Qin, what if Asan and the French find out that the parts they bought from us still can't be used, what should they do?"
"What else can we do? Just think of a way on your own. They are not as good as others. What does it have to do with us?" Qin Tao was very calm.
Money has been made, but the technology is not provided to them. The money of Asan and France is really easy to make! Especially the French, do they think they got the technology for free and took a huge advantage?
The advantage can only be taken by our Mingzhou Group!
Lao Maozi used to be able to build aircraft carriers. If it were later, the nuclear-powered Ulyanovsk could be built, and Lao Maozi's surface ship force would become the second in the world. Although Lao Maozi still stubbornly insists on
That kind of warship is called a heavy aircraft-carrying cruiser, and it cannot hinder the expansion of Lao Maozi's navy.
Now, with the repair of the Kuznetsov, the addition of two amphibious assault ships, and the renovation of other cruisers, the strength of the Lao Maozi Navy has begun to continuously recover, and they are also looking forward to returning to
peak.
Every once in a while, the Lao Maozi Navy will publicly display its aircraft carrier plans, ranging from light to heavy, from conventional power to nuclear power, which reflects their pursuit of aircraft carriers. Although it is a PPT project, it still has to be enjoyable.
!
However, no matter what the previous models were, they all had one thing in common: the bow jumped over the deck, and a catapult was installed on the oblique angle.
For Lao Maozi, choosing this option is not only a nostalgia for the nuclear-powered aircraft carrier of the past, but also a choice forced by reality.
Lao Maozi is located in the north, and their navy's military port even has a long freezing period. It has an inherent disadvantage in using steam catapults: the overflowing steam can easily be frozen on the deck, causing the deck to freeze.
The consequences of this are quite dire. The aircraft carrier will soon lose the ability to take off and land fighter jets.
Although there are many arguments that catapults can also be used in high latitudes, just add a little salt and it will be enough. If you think about it for a while, you will realize how ignorant these statements are.
I won’t be fooled. If I add salt, it won’t freeze, won’t it corrode? Are you still dissatisfied that the salt content in the sea is not high enough?
The catapult can be used to allow carrier-based aircraft to have more efficient dispatch capabilities, but the bow of the ship must be a jump deck. In case the catapult is frozen, there is still a jump deck on the bow of the ship that can be used.
Although the jump deck cannot dock aircraft, which greatly reduces the number of fighter jets on board, it can play a key role at critical times!
But this time, Lao Maozi's latest aircraft carrier plan has eliminated the jump deck, and the entire warship deck is flat!
Facing a large number of journalists, Nicholas introduced it personally.
"This is our latest Manatee-class nuclear-powered aircraft carrier. This aircraft carrier has now entered the detailed design stage and is expected to begin formal construction next year. This aircraft carrier will become the most advanced aircraft carrier of our Dalai Lama Navy!"
"This aircraft carrier has a full load displacement of 90,000 tons and uses two nuclear reactors with a thermal power of 700 megawatts. All the energy is used to generate electricity, using the most advanced ship-wide integrated power and ship-wide electric propulsion solutions..."
The design of this aircraft carrier is quite satisfactory, and it looks like a replica of the Dongfang 003 aircraft carrier!
"We plan to install two electromagnetic catapults on the bow of the ship and one on the angled deck. We will carry advanced carrier-based stealth fighters..."
What Nicholas said has noses and eyes, the outside world has to believe: Da Mao has indeed launched a new aircraft carrier plan! Da Mao's navy has passed the lowest point and has begun to move towards a new era.
The Mao Navy will soon have a modern aircraft carrier! With a weight of 90,000 tons, it will rank third in the world!
Faced with Mao's propaganda, the French could no longer sit still and immediately announced their latest aircraft carrier plan.
"We in France plan to build a brand new aircraft carrier. We call it PANG. This aircraft carrier has a full load displacement of 80,000 tons and will have two electromagnetic catapults!" Chapelon's face was filled with pride: "This will be the largest aircraft carrier in Europe.
Advanced aircraft carrier!"
In fact, the full-load displacement of their planned aircraft carrier is only 75,000 tons, but if you round up, wouldn’t it be 80,000 tons? It will not be much worse than the 90,000-ton super aircraft carrier promoted by Mao, and at the same time, it will overwhelm the British aircraft carrier.
"After years of research, our navy believes that two catapults are enough. Although American aircraft carriers have four catapults, two of them are almost always idle..."
This is of course due to poverty. Two catapults are extremely expensive, and one more catapult will feel painful. Of course, the French have long been accustomed to this kind of catapult layout.
There is one for the bow and one for the beveled deck. They used to be laid out like this because the deck area was small, but they are still laid out like this now to save money!
Take the bow of the ship as an example. If the catapult is placed on the right, a row of parking areas can be left on the left. This row of parking areas can accommodate at least ten fighters!
A catapult can also be placed on the left angled deck and arranged to the left, so that the take-off point will be away from the main runway on the angled deck and will not interfere with runway operations. This is how this Oriental was designed.
"At the same time, we will continue to use nuclear power. We will use a newly developed nuclear reactor to drive the aircraft carrier so that it can run at a high speed of more than 30 knots!"
The Charles de Gaulle aircraft carrier has been known as the slowest nuclear-powered aircraft carrier in the world for many years. Now that we are building a brand new aircraft carrier, we must get rid of this hat!
"Excuse me, does France have these technologies? For example, electromagnetic catapults?" a reporter asked below.
"Of course, we are developing relevant technologies and will conduct ejection tests next year at the latest!"
