Newport News Shipbuilding, USA.

This is the only shipyard for U.S. Navy aircraft carriers. It is not only building aircraft carriers, but also renovating them.

For an aircraft carrier that can easily have a lifespan of more than 40 years, it needs to enter the dock for modifications in about fifteen to twenty years, and upgrade many of the backward equipment on the aircraft carrier. If it is nuclear powered,

You still have to cut the deck and replace the fuel for the nuclear reactor inside, which can easily take a year or two.

Currently, the only aircraft carrier under construction at Newport News Shipyard is the USS Ford, while there are two or three aircraft carriers being refitted. Among them, the USS Kennedy is the most conspicuous because there is a row of long work sheds on its deck, as long as

A full one hundred and fifty sixty meters!

The USS Kennedy aircraft carrier started construction in 1964, was launched in 1967, and entered service in 1968. It has been nearly forty years now. When it was being built, it was originally planned to use nuclear power, but later it was felt that nuclear power was not mature yet, so it was switched to

Heavy oil boiler.

Therefore, it is the last conventionally powered aircraft carrier. Some say it is a Kitty Hawk class, while others attribute it to an improved Kitty Hawk class. In short, this aircraft carrier is already very old and should be retired.

No one thought that the U.S. Navy would actually use this aircraft carrier as an experimental ship modified with electromagnetic catapults. When they received the news, people at General Atomics suddenly felt bursts of nervousness.

They have been testing at the Navy's Lakehurst Aviation Engineering Station for several years, but there have always been problems. There are still so many problems that have not been solved, and now they actually have to move the electromagnetic catapult onto the aircraft carrier!

This is simply a rush!

"Sulich, you must speed up the time. The Navy can't wait." George Sulich, the person in charge of the electromagnetic catapult system, was busy in the long iron house on the deck, and then heard a voice.

He raised his head and saw Rolf Bartz, the project manager of the Ford aircraft carrier, walking in with a heavy heart: "The Navy hopes to use this aircraft carrier to conduct experiments first and complete the electromagnetic catapult experiment as soon as possible, so that when we can

When outfitting an aircraft carrier, we will have successful experience to draw from."

It was originally planned to equip the Ford, but unfortunately the progress was too slow, so the Navy decided to use old ships to modify and test them.

"Installation on an aircraft carrier is a big project, and you are unwilling to allow us to use the dock. We can only moor at this pier. A slight shaking of the deck may cause serious errors." Sulich said: "Even a millimeter.

Installation errors will cause the catapult to be scrapped, so we must be cautious."

Sulich soon found the reason.

Once the seawater is emptied from the dock, the aircraft carrier will become stationary. On the dock, even a 100,000-ton aircraft carrier will sway slightly. This is inevitable and usually doesn't matter, but if a catapult is installed, then

It will cause serious interference.

The accuracy required for electromagnetic catapults is very high.

"In other words, the electromagnetic catapult on our USS Ford needs to be installed before it is launched into the water?" Bartz asked.

"No, after you have welded the hull, you must first launch it into the water and outfit it for a period of time to allow the stress on the hull to be released, and then drive it back to the dock and hand it over to us for installation."

This is no joke. The welded hull will have residual stress. After it is launched into the water, the hull will deform, which has no impact on normal use. For electromagnetic catapults that require excellence, they were originally installed, but after launching into the water, they found that

The original straight line turned into a twist, and we had to start over again!

"That's impossible. Once you hit the water, you can't go back to the dock. Our dock is very precious."

For any shipyard, the dock is a precious resource. Asan's aircraft carrier was launched into the water many times just to free up the precious dock. But Barthes asked to be launched into the water before returning to the dock?

When the last aircraft carrier goes off, it’s time for the next aircraft carrier to come in!

"That's absolutely not possible. When the Oriental people installed the catapult, they drove back to install it without seeing it."

"Only those who go to the ground will know how the Orientals did it." Speaking of this, Suliqi was very helpless. He didn't know at all that his own research and development was earlier, but in the end he got up early and stayed late.

The progress is far behind that of the East!

"By the way, I heard that electromagnetic catapult technology suddenly appeared in Da Mao's hands. This technology should be from the East. Our intelligence personnel should have obtained the technology."

"Really? Where?"

"Here." At this moment, a voice came from outside.

Michael Rand from a certain department of the Naval Aviation System walked in, holding a USB flash drive in his hand: "We have obtained some of the technical content, which can be handed over to you, but..."

The intelligence was obtained by relevant departments, and General Atomics is a private company. Normally, this kind of information should not be handed over to the other party. However, now this is the only company in the United States that is researching electromagnetic catapults. In order to make our own electromagnetic catapults

If the catapult matures as quickly as possible, it must be handed over to the person in front of you.

"but what?"

"You must ensure that the electromagnetic catapult is installed and tested within one month!"

A month? Are you kidding? A year is enough!

But...if he doesn't agree, then Rand is likely to hand over the information to other companies and start a competition again.

"Okay, just one month." Sulich nodded: "Give me the information."

Before Rand handed over the information to Sulich, Barthez on the side spoke: "You have been installing for three months and have only installed about 20 meters in length. Next, how can you ensure that the remaining parts are installed within a month?"

More than a hundred meters?”

You can't just talk nonsense. You just said you wanted a dock, but now? It will take another month to install it. In short, the dock will not be given to you. Don't pass the responsibility to us then!

You can't just use the dock if you want! The shipbuilding company's dock arrangements are often finalized a year or two ago. If he uses it, everything will be messed up later.

This chapter is not finished yet, please click on the next page to continue reading the exciting content! "We will use half a month to install all the modules. After they are installed in place, we will make precise adjustments at once." Sulich said

.

They are now installing and debugging one piece at a time, taking their time. In fact, the main reason is because they know that the technology is not mature and they have to test it after it is installed. And they have no confidence that problems will definitely occur when they are installed and tested.

It's better to just work here.

Now, with the technology from the East, it’s easy to say! Get the technology first, then use the technology from the East to conduct research, compare it with your own to find problems, and soon your own electromagnetic catapult will mature!

Therefore, in order to obtain technology, he is willing to make any commitment.

"Okay, as long as you can do it!" Rand handed the information to the other party.

Butetzi understood: These guys have been dawdling before, but now they have hope and are starting to work seriously. It's shameful, pitiful, and pathetic!

After receiving the information, Sulich quickly inserted it into his laptop and opened it.

"Hey, why can't I open this file?"

"What format is this?"

"You need to use a Loongson computer. The instruction set of our computer is different from theirs." His subordinates quickly reacted.

Nowadays, computers are divided into different camps. Loongson computers rely on their ultra-high performance to outperform other products and have become the mainstream products in the world. However, in order to avoid leaks and accidents, the United States continues to use Intel computers, and the instruction set is not the same.

Compatible, but the program is not compatible and has now been marginalized.

Even in the United States, most people like to use Loongson. Only special departments use Intel computers to avoid leaks.

"Change the computer!"

Soon, the USB flash drive was inserted into a Loongson computer used for entertainment, and the file was finally opened, and Sulich studied it carefully.

The technical principle of the electromagnetic catapult is not complicated and is mainly composed of a linear motor, an energy storage system, a frequency conversion control system and a power supply system.

The first thing to look at is the linear motor part, which is to spread out a motor directly and turn rotation into translation.

The technical route adopted by the Easterners was exactly the same as ours, but why did they succeed while ours repeatedly encountered problems?

Sulich continued to read, and then saw the frequency conversion control system part.

Outsiders always think that linear motors are the key. After all, the power of this linear motor is tens of megawatts, and the instantaneous power can even reach hundreds of megawatts. The temperature can jump to hundreds of degrees when power is turned on.

However, the frequency conversion and control system are more important!

The Yankees use a medium-voltage AC system, and linear motors are also AC motors. But if you want a linear motor to work, you need high-frequency AC, so you need an inverter. If you want to power a motor with tens of megawatts, you can

Not a simple matter.

The working time of the inverter is only a dozen seconds, but the power when working is extremely powerful. Even the power consumed by the cooling system alone is as high as more than 500 kilowatts.

For the Americans, this system is very important. They have always kept it secret. Even if other systems took photos and showed them to the outside world, they never showed this system.

For Sulich and others, this system is also the most difficult, but I don’t know how the Orientals solve it?

Sulich opened it, and there were dense circuits inside, some of which he had never seen before.

"Bring this USB flash drive back to our company, then translate it, and let everyone in the company study it." Suliqi knew that he could only take a rough look to determine whether the technology inside was true or false. In the end, he had to ask people from the company to come and study it.

look.

They definitely can't use Loongson computers and have to use their own Intel computers. Although they are not compatible now, it's just that they haven't done it. In fact, Intel has invented special translation software to facilitate the transfer of data between the two computers. It's just that

It just takes time.

"Yes." The subordinate took the USB flash drive and got busy.

He didn't know that the moment this USB flash drive was plugged into their own computer, their technology would no longer be a secret.

East.

"Mr. Qin, everything went very smoothly." Xu Zhengyang said: "They attach great importance to our technology, brought the technical information back to their company, and then started translating it. Before their computers had finished running the translating program, they

All the data in the computer has been sent to our designated server."

"Well, they didn't notice anything?"

"Yes, our electronic technology has far surpassed theirs. It is too easy to do this. If it weren't for the fact that they are using an intranet and we need to build a bridge, we would have obtained their technology long ago.
