After a thousand years of trading, start a million barrels of oil

Chapter 200 Pirates

And following Shi Yang's gaze, on the 055A, on the side of the main gun, there were 3 people standing there.

In the middle is Jiang Fan. Standing on his left is Academician Ma Weiming, a top expert in electromagnetic technology and all-electric drive technology.

And the person standing on his right is also an academician, and he is also the chief designer of the 055 drive, Academician Xu Qing.

Xu Qing successively served as the chief designer of my country's first open-sea stealth frigate, the third-generation frigate, and the first [-]-ton destroyer, and made significant contributions to the navy's strategic transformation from offshore defense to open-sea defense.

And these two national treasure-level academicians accompanied Jiang Fan and stood on both sides of him at this moment.

"I didn't expect the electromagnetic gun to be on the ship so soon." Jiang Fan gently touched the gun pipe.

After listening to Jiang Fan's words, Ma Weiming also laughed and said, "That's not because your materials were delivered in time, and I didn't expect that the high-temperature resistant materials have been developed just a few months after I put forward the demand.

I'm faster in scientific research. I didn't expect you to be faster than me. The waves behind the Yangtze River push the waves ahead. "

Jiang Fan's tungsten-carbon alloy material has been applied to the gun barrel, which solves the problem of the influence of thermal erosion and current erosion on the gun barrel during the charging and firing process of the electromagnetic gun.

Jiang Fan also laughed, and at the same time waved his hand and said, "Mr. Ma, you are overrated. I just provided a high-temperature-resistant material. Compared with your contribution, it is really nothing."

Ma Weiming's eyes shifted from the barrel to the position of the gun body, and said: "It's not just high-temperature resistant materials. You think, this is two or three years earlier than we expected to board the ship. Just a high-temperature resistant material can't do it." so long in advance."

"That's...?" Jiang Fan was also a little puzzled.

"It's a battery." Ma Weiming answered Jiang Fan's words: "The principle of the electromagnetic gun is to accumulate a large enough charge in a short period of time to charge the capacitor, and then the Lorentz force generated by the capacitor will strongly accelerate the shell placed in it. .

Then it is launched at ultra-high speed, using the huge kinetic energy generated by its ultra-high speed, as well as the stability and no time difference brought about by high-speed movement, to achieve the effect of accurately striking the target.

However, in order to charge such a large amount of electricity in a short time, it is definitely unrealistic to rely on fuel to generate electricity. Batteries must be used, which places great demands on the battery energy storage capabilities of electromagnetic guns and ships.

At least one hundred megajoules is required, which is already the energy storage scale of the electromagnetic ejection device of a large aircraft carrier.

But a destroyer does not have so much space to install so many batteries, even if this model has been equipped with an all-electric propulsion system, the mechanical transmission shaft across the bottom of the ship is canceled, and the usable space inside the hull has been greatly improved.

But if all of them are used to install batteries, many other advanced functions will be limited, and even if this is done, the management efficiency will decrease due to the increase in the number of batteries, and the best results will still not be achieved.

Therefore, the best choice is not to expand the number of batteries, but to greatly increase the energy density of a single battery.

But I thought that this could not be completed overnight, so 055A is already considering the second option for construction.

But your success in the field of new energy batteries has given us hope again.

The 1000Wh/kg ultra-high energy density power battery you developed not only enables new energy vehicles to achieve a 2000-kilometer ultra-high battery life, but also solves the problem that electromagnetic guns need a large reserve of electricity to complete instant charging.

Therefore, you helped us solve the two most critical technologies for the electromagnetic gun to be able to board the ship today.

On behalf of the entire electromagnetic gun research and development team, thank you! "

Jiang Fan waved his hand to show that it was nothing, he didn't dare to take credit in front of this person.

But before he finished his humility, Academician Xu Qing beside him also spoke, looked at Ma Weiming and said, "Old Ma, don't bother talking about your electromagnetic gun.

The overall performance of this new type of 055A can be so much improved compared to the previous generation. In addition to your all-electric system modification and electromagnetic gun, don't forget Comrade Jiang's high-end CNC machine tools.

Ships are the key application fields of high-end CNC machine tools, including warships, CNC gantry boring and milling machines for hulls, gantry machining centers, and crankshaft machining of diesel engines that require crankshaft lathes. , Also need CNC crank vertical lathes for these.

It can be said that almost every part of the hull, especially the precision parts, is inseparable from Comrade Jiang's high-end CNC machine tools.

If it weren't for him to improve our domestic precision to an order of magnitude higher than that of foreign countries, the performance of 055A would not have been improved so much. The improvement of this piece of technology has solved many of my design problems. "

"You have to thank him for the hull." Ma Weiming also joked.

Xu Qing also smiled and said: "Of course, I came this time to thank Comrade Jiang. And don't tell me, old horse, if you don't have the ultra-high-end chip designed by Comrade Jiang to speed you up, your all-electric drive transformation Can it achieve the effect like it is now?"

"Hahahaha~" The two of them looked at each other and smiled after finishing speaking.

Jiang Fan can only laugh with these two bosses, the latest model of the 055 Big Drive has a military medal as big as mine? !
"Three experts, stand closer and I'll take a picture for you." At this time, an assistant came over and said.

With a click of the shutter, the Polaroid photo was delivered to them.

Above, two elderly but still handsome academicians enclose a young man in the middle. The three of them together contributed to the birth of 055A, the strongest steel guard at sea, and this photo will also be recorded in the annals of history forever.

The warship traveled all the way and passed many islands. Ma Weiming pointed out these islands and introduced them to Jiang Fan. These are our Nansha Seven Sons, seven artificial islands created by our technology of blowing sand and reclamation.

Including Meiji Island, Zhubi Island, Yongshu Island, Huayang Island, Chigua Island, Nanxun Island and Dongmen Island.

The most famous of these is Yongshu Island, the destination this time, which is the government residence of Nansha District, Sansha City.

It has a large area of ​​atoll, strong scalability, and excellent geographical location, so it was chosen for the initial construction of the marine observatory and many other advantages.

But this is not the most important thing. The most important thing is that this island has fresh water due to its unique coral structure, which is extremely rare in the entire Nansha Islands.

You know, how precious fresh water is in these islands far from the land. If you want to station people on it, you need to transport fresh water over thousands of miles by plane and freighter. It is hard to say whether this transportation process is risky at certain special times.

This is also why when we reclaimed the island, others laughed at us as stupid, and the loss outweighed the gain. As a result, the appearance of such abundant fresh water resources directly made them dumbfounded.

So this also established its leading position among the seven sons.

The warship sailed into Yongshu Island at last.

The overall shape of Yongshu Island is like a bullet, but the tail of the bullet is missing a piece, which extends to the abdomen. This is a specially built military port.

After parking, a group of people went to the island to rest and resupply. This is basically a small city with residential buildings, hospitals, supermarkets, entertainment facilities, and even a 3000-meter runway that can take off and land any large aircraft.

Jiang Fan made some visits and experiences, and finally came to the Yongshu Island Memorial Room.

There are some iron sheets, sunshades and other objects stored in it. Jiang Fan didn't know why these things were put there. He didn't understand the meaning until he read the introduction of the seat on the TV on the wall and the photos at that time.

At the beginning, Yongshu Island was just a small rock outcropping, and three people couldn't turn away from it. But decades ago, everyone's point of view was to get the land economy right first. What kind of ocean do we need?
The navy had no choice but to send a few soldiers to stand guard on the reef, live in stilt houses like shacks, and plant a red flag.

The average temperature is 40 degrees Celsius, high temperature, high humidity and high salinity all year round, and there are many typhoons, and a wave can knock people down.

And the feeling of endless loneliness after falling asleep, except for the waves, is even more difficult to describe in words.

But they held on, only because of the red flag behind them.

It is precisely because of their perseverance that the small reef with only a place to stand on it has become Yongshu Reef where planes can fly and park warships today.

Jiang Fan's eyes were a little moist looking at the picture, the soldiers are so cute.

And the moment he turned his head, he saw the old red flag kept in the glass cabinet, although it looked very worn out after being exposed to rain and sun.

But it is just a seed, and when it is buried, the most brilliant flowers will bloom.

Jiang Fan was even a little hesitant to take it away, but after thinking about it, he was relieved. This red flag has long been transformed into a spirit, engraved in the hearts of everyone who has participated in and witnessed this process, and it has long been immortal .

After Jiang Fan took the flag and had a meal at the restaurant on the island, he was ready to go back.

055A has also completed this patrol and supply mission and is preparing to return.

But at this moment, the captain received an instruction that pirates hijacked a Cambodian merchant ship in a certain area of ​​the high seas, and Cambodia asked me for help.

055A was the closest to that sea area, and was dispatched to rescue.
