Eyes back home.

Liaodong Province, Dalian City.

At present, there are two shipyards that can build 100,000-ton nuclear-powered ships, the Dalian shipyard is here, and the other is the Jiangnan shipyard.

Inside the huge dock, the first domestic aircraft carrier is under construction.

But today's events have nothing to do with domestic aircraft carriers.

Inside the dock on one side, the debris inside has been cleaned up, which is a super-large dock that can build 200,000-ton oil tankers.

Of course, this kind of dock can only be said to be general in China, after all, there are dozens of shipyards in China that can build ships of 300,000 tons ~ 500,000 tons.

Inside the dock, the keel of a ship is being built, and with the assistance of a large gantry crane, workers are busy splicing and assembling it.

Ship designer Zhao Dian and others are discussing details with shipbuilding engineer Wang Jianshe and others.

"Designer Zhao, we really want to build this kind of thing," Wang Jianjian, who was holding the design sketch, asked again.

Zhao Dian raised his eyebrows and replied: "It's from above, what do you say?"

Wang Jianjian, who smiled bitterly, complained: "But what is this thing made and put in a museum, it takes up space." ”

Zhao Dian spread his hands and replied: "Don't worry about it, this ship is not useless, first, it can verify some new materials, and second, it can accumulate some armor technology." ”

"Okay!"

Wang Jianshe looked at the design sketch in his hand, and then looked at the aircraft carrier in the dock next door, not to mention how depressed he was.

Others build aircraft carriers, he builds antiques.

"Lao Wang, don't be perfunctory, this is one of the key tasks above." Zhao Dian reminded.

"Yes."

Zhao Dian also vomited bitterness: "I was also confused at the time, in order to design this ship, I ran for a few months, went to find a lot of Yamato-class restoration design drawings, and used the simulation space and a large group of people for more than half a year to complete the ship." ”

"But what's the use of this kind of iron coffin, and people don't fight against your battle line, isn't it right to put the museum for tourists to see! This is an enlarged version of yours, and it's not really Yamato-level. ”

"Hell knows."

The two of them complained while watching the keel laying.

The keel is laid very quickly, and in the modern shipbuilding industry, most shipyards, especially large shipyards, use the sectional shipbuilding method.

The so-called sectional shipbuilding method is to design the ship as modules similar to building blocks, which are then manufactured from other supporting factories and transported to the shipyard for assembly.

And the ship on the dock is a partial segmented shipbuilding scheme.

Why partially, because this ship will adopt a completely new shipbuilding method to complete the purpose of rapid shipbuilding.

The laying of the keel and the high-strength alloy frame was very fast and took less than a week.

Today, Wang Jianjian, Zhao Dian and others are waiting for the 24 important modules coming from Lingnan. Seven or eight Chinese fastest ^ mobile terminal:://

Zhang Qinghai, chairman of the Lingnan Nuclear Industry Equipment Group, personally escorted two pieces of equipment over here, which was the Jinwu II nuclear fusion reactor that had just been successfully developed.

After modularization, the Jinwu II is composed of 12 small modules.

"Chairman Zhang, is your equipment here?" Wang Jianshe hurriedly asked.

"Already at the port, our engineers have arrived." Zhang Qinghai handed the list to the other party.

In order to keep secrets, the names of nuclear fusion reactors are all labeled as nuclear fission reactors, and the secrecy is very tight.

Over the next few days, under the guidance of engineers from Lingnan Nuclear Engineering, the shipyard quickly assembled the 24 modules of the fusion reactor.

Then there was the installation of electric motors and propellers, which was also the first attempt by the Dalian shipyard to convert the steam turbine into an electric motor.

In fact, the electric motor also has the advantage that it can be started very quickly and can be accelerated in a few minutes, unlike a steam turbine that needs to be warmed up for a while.

In addition, it is also to support the Jinwu nuclear fusion reactor, because the Jinwu nuclear fusion reactor is directly used to generate electricity, and if a steam turbine is used, it will be redundant.

Moreover, the volume and weight of the motor are only about 30~40% of the steam turbine, which can greatly save the space and payload of the ship.

The ship is an enhanced version of the Yamato-class, with a total displacement of 167,000 tons, and is equipped with two Jinwu-2 nuclear fusion reactors.

However, a lot of data and equipment modules are unknown to the Dalian shipyard, especially the electrification equipment, weapon modules, etc., which are confidential parts.

For example, Zhao Dian, the chief designer, only knows the general shape and weight of the modules that the ship needs to be equipped with, and he doesn't know the function.

After the installation of the two Jinwu II nuclear fusion reactors, security personnel stood guard 24 hours a day.

Time flies.

By September 15, the ship's keel and high-strength alloy frame, energy system, and power system had been arranged.

A layer of formwork similar to that used to build a building has been installed around the frame of the ship.

Zhao Dian, Wang Jianshe and others once again came to gather on the tower.

"Start pouring." Wang Jianshe commanded with a walkie-talkie.

"Roger."

Six special pumping trucks continuously pump up the seawater source, filter the sand and debris, and directly inject it into the formwork.

The rock-forming agent at the bottom of the ship was placed in advance, and it quickly expanded up, filling the entire formwork without leaving any gaps.

In less than an hour, the hull of the hull and the watertight bulkhead inside were formed in one piece.

"Report, hull pouring complete."

"Prepare to disassemble the formwork." Wang Jianshe commanded.

"Roger."

With the assistance of gantry cranes and boom cranes, pieces of formwork were dismantled, revealing off-white shells.

Unlike the texture of metal, the texture of artificial rock and stone is similar.

Wang Jianjian's heart is also up and down, using this artificial rock to build ships, they are trying for the first time, and there is always not much bottom in their hearts.

Obviously, this kind of artificial rock is the same as the artificial rock used in the South China Sea to build islands, but there are some differences between the rockmaking agent used in shipbuilding and the rock building used in island building, similar to FRP.

Not only is it stronger, but the density and hardness are also very suitable.

Generally, the strength of shipbuilding steel is between 300~700MPa, while the strength of shipbuilding steel in rice and Lucia can reach more than 1000MPa, and the strongest in China is 690MPa.

The strength of special artificial rock can reach 950MPa, and the overall strength of the internal high-strength alloy frame can reach about 1200MPa.

In addition, the toughness and density of the ship are not bad, the density of special artificial rock is only about 71% of the ship steel, and the toughness can reach about 127% of the general military ship with the blessing of the alloy frame and keel.

Of course, these data are simulated and calculated in the simulation space, and the ship is still being built for the first time, whether it is a mule or a horse, and it is only known when it is pulled out and yo-yo.

With the removal of the formwork piece by piece, more than half of the hull was exposed, and now the island and deck were left unpoured.

They needed to remove the formwork of the internal compartments before they could pour the deck and ship island.

The removal of the outer formwork is relatively simple, and the trouble is the internal cabin, and the dismantling work took three days to complete the cleaning of all the formwork.

However, before pouring the deck and the island, they had to carry out another task, which was to test the tightness of the hull and watertight compartment.
