Open an aircraft carrier to fight against Japan

Zhang Shouen was taken aback for a moment, and asked, "Shuai Lin, why do you need to dismantle such good shells?"

Lin Yuan smiled and said: "We need to replace the charge inside, that's why I asked you to use black powder charge shells, black powder can be poured out, and black ladder mixed explosives are put in after heating and melting , it is solidified inside, and we have no way to replace it."

Several soldiers took out disassembly tools, and it took a lot of effort to disassemble the warhead, revealing a lot of black powder inside.

Lin Yuan said: "Pour out three quarters of the black powder inside." Then he said to Liu Yufeng and his subordinates: "You guys, go and grind these graphite into powder."

Everyone didn't know what Lin Yuan wanted to do, but they knew that they couldn't understand even if Lin Shuai explained the reason to them, so they simply stopped asking and went to work separately.

At this moment, Fade Chen came to look for Lin Yuan, saw the bustling labor scene, so he asked with a smile, "What are you doing?"

Lin Yuan smiled and said, "I'm making new weapons."

Fade Chen gave a "hmm" and said, "I'm here to tell you that Xu Feng has already returned to Hunchun City."

Lin Yuan asked in surprise: "What is he going back for? Why is he leaving in such a hurry?"

Fade Chen said: "He said that there are still people in the city, and he wants to go back and cooperate with us inside and outside. He heard that the Russian army is going to seal the city, so he left in such a hurry."

At this time Zhang Shouen came over and asked, "Shuai Lin, according to your request, three-quarters of the black powder has been poured out, what should we do next?"

Lin Yuan saw that Liu Yufeng and the others hadn't finished, so he said, "Wait until Liu Yufeng finishes grinding the graphite." Fade Chen looked at Zhang Shouen and Liu Yufeng, and said with a smile: "I know what new weapons you are going to do, you want to make carbon fiber Bomb, right?"

Lin Yuan smiled and said, "Do you still know about carbon fiber bombs? It's really not easy!"

Fade Chen said: "Although I don't know as much as you, I have heard of this kind of bomb. This kind of bomb is specially used to deal with power generation systems, but..."

Speaking of this, Fade Chen frowned slightly, and Lin Yuan asked, "What did you think of?"

Fade Chen said: "Isn't your approach too rough? Will it work?"

Lin Yuan smiled and said: "Compared with ordinary bombs, carbon fiber bombs mainly need to consider three issues, the manufacture of carbon fibers, the opening of the warhead and the throwing of carbon fiber clusters. I have solved these three problems with local methods."

At this time, Liu Yufeng came to Lin Yuan with a box of ground graphite powder, and asked, "Do you think this will work?"

Lin Yuan said, "Grind it finer."

Liu Yufeng then went back to grind it again, and it took a while to finish it. Lin Yuan said: "Put all these graphite powders into the warhead of the shell."

Zhang Shouen led the soldiers to put the graphite powder into the warhead. Lin Yuan waved to everyone and said, "Come on, let's try this shell."

When everyone came to the shooting range, Zhang Shouen ordered his subordinates to bring an 82mm mortar, dug a shallow hole in the ground, then put the mortar seat plate into the shallow hole, opened the bipod on the gun body, and asked Lin Yuan Said: "Shuai Lin, where should we aim to fight?"

Lin Yuan smiled and said, "You don't need to aim at the target, just shoot out at will."

Zhang Shouen operated the cannon himself, put the projectile into the cannon body, and with a "boom", the cannonball flew out from the muzzle and landed on the ground with a "bang". After the sound, the cannonball poked straight on the ground without exploding!

Zhang Shouen frowned, and said, "This may be a bad bomb!"

Lin Yuan got up and walked towards the shell, Zhang Shouen hurriedly stopped him and said, "Shuai Lin, this bad shell may explode at any time, you can't go there, it's too dangerous."

Lin Yuan smiled and said: "It's okay, the shell has already exploded, if you don't believe me, come and see with me."

Zhang Shouen walked up to the cannonball suspiciously. Lin Yuan pointed at the cannonball and said, "Look at the cracks on the cannonball. The reason the cannonball didn't explode was because the amount of black powder inside was too small. Go back and make another cannonball. This time Change the amount of black powder in the shells to one-third."

Zhang Shouen went back to follow suit, and soon made a new cannonball, and tested it again. This time, the cannonball was blown to pieces after it hit the ground. Although some graphite powder was ignited, a lot of graphite powder still drifted out.

Lin Yuan smiled and said, "Very well, according to this ratio, make more shells of this kind, and we will call them graphite shells in the future."

Chen Fei said: "If our shells can blow up the transformer, what else do we use graphite powder for?"

Lin Yuan said: "Our shells don't have enough range, so we must use graphite powder."

Fade Chen looked bewildered, and thought: "Could it be that the range of the shells will increase after adding graphite powder?" He wanted to ask again, but Lin Yuan said to him: "Okay, you will understand tomorrow, we Go back and deploy a method to break through the wire."

The next day, when everything was deployed, Lin Yuan led a battalion to the outskirts of the transformer. The Russian army also saw the Chinese army, so they were heavily guarded.Lin Yuan said to Zhang Shouen: "Replace the instant fuze on the projectile body, this time we will use the time fuze."

Zhang Shouen asked: "Shuai Lin, how long is our time fuze set for?"

The time fuze produced by the arsenal under Lin Yuan’s command uses a clock and clock timing structure, that is, the primer is ignited after the gear rotates a certain number of times. When using it, different times can be set according to the nature of the target. Lin Yuan laughed. , Said: "Set the time at five seconds."

Zhang Shouen fixed the time fuze of the cannonball and put it into the cannon body. The cannonball slid down the barrel and made a "cracking" sound. Rush to the sky.

When the shell flew to the highest point, it did not continue to fall, but exploded in the air with a "bang", and the graphite powder inside was blown by the wind, fluttering and falling on the Russian army's position.

Lin Yuan turned his head and said to Fade Chen: "My intention is not to let the cannonball blow up the transformer, but to let it explode in the air. I just calculated the time for the fuze to be set according to the ballistic performance of the cannonball and the direction of the wind. , the graphite powder after the shell exploded was just blown by the wind and landed on the Russian army's position."

Fade Chen nodded. It turned out to be the case. After speaking, he pointed to the transformer and said, "Look, their transformers haven't changed a bit!" Lin Yuan smiled helplessly: "Things made with earthen methods are not good. It appears that there was not enough carbon fiber falling on the transformers of the Russian army."

Chen Fei rushed to ask: "Then what should I do!"

Lin Yuan couldn't help laughing out loud, and said, "How come you have forgotten such a simple truth, wouldn't it be enough to fire a few more shells?" Fade Chen also laughed, and Zhang Shouen fired more than a dozen shells, falling to the ground. There is more and more graphite powder on the transformer. The graphite powder enters through the heat dissipation holes outside the iron box, and the light graphite powder is adsorbed on the coil of the transformer. Graphite is a good conductor, and it immediately forms a The loop generated a huge current in an instant, and the huge heat generated by the current actually melted the steel coil.

When the transformer is working, it will generate a lot of heat, which is dissipated by the cooling oil inside, but the huge heat directly ignites the cooling oil, and flames burst out from the iron box of the transformer.
