Open an aircraft carrier to fight against Japan

When the milling cutter walked around the projectile body, the young man stopped the machine, put on a pair of gloves, grabbed the loose shell of the projectile body and lifted it vigorously, the shell was lifted, revealing a gray-white solid substance inside. , Lin Yuan pointed to them and asked: "That should be explosives, right?"

Luo Chaoying came over and took a look, then turned around and said, "Lao Li, come and have a look, what kind of explosive is this?"

An old man came over, this person is the old Li in Luo Chaoying's mouth, named Li Mingguo, an expert in pyrotechnics chemistry, he glanced at it and said: "I think the main ingredient should be Hexogen, other additives can't be seen yet ,What do you think?"

Luo Chaoying said with a smile: "Not all explosives can produce a jet effect. This requires explosives with a high detonation velocity. Explosives such as TNT cannot be used in armor-piercing projectiles. The detonation velocity is too low, so I think this should be black. Sorkin."

Lin Yuan said in surprise, "Has the Japanese also produced black sorkin?"

Li Mingguo smiled and said: "As long as there is investment, it will be a matter of time to get these things out. Don't be surprised. I will have these explosives removed, and I will measure them with a spectrum analyzer to see if there are other things added to them. "After Li Mingguo finished speaking, he asked his assistant to remove the explosives inside. This kind of explosives is installed under pressure, so it is pressed tightly inside the projectile body. It took a lot of effort for several people to remove the explosives. .

After the explosives were removed, there was only an awl-shaped cover left inside. Lin Yuan knew that the conical cover was the core component of the armor-piercing projectile, and the metal jet was formed after it was melted by the explosives. The material and shape of the conical cover Size directly affects penetration depth.Luo Chaoying took out the conical cover and said to Lin Yuan: "Let's analyze this conical cover, and then combine it with the performance of explosives to calculate the penetration depth of the Japanese armor-piercing bullets, and then we can design defensive measures!"

Lin Yuan asked, "How long will it take?"

Luo Chaoying said: "Two days, we will hold a meeting at this time the day after tomorrow. At the meeting, we will announce the results of the research, and then we will discuss what defensive measures to adopt."

Lin Yuan said: "Then as soon as possible." Lin Yuan returned to the headquarters and received a letter from Yuan Shikai requesting the return of Masamune Tada. Returning Masamune Tada was simply Lin Yuan's plan to get the rockets, and now he has the rockets , Tada Zhengnan is useless logically, but in order to confuse Yuan Shikai, Lin Yuan still acted like he wanted to withdraw his troops and wanted to return the people, and replied to Yuan Shikai's letter seriously.

Two days later, Lin Yuan invited the experts to a meeting. At the meeting, Luo Chaoying said: "After the analysis of our expert group, the explosives used by the enemy's armor-piercing bombs are passivated Hexogen, but there are still some impurities in them; The material used for the shape cover is copper, that is, copper with relatively high purity. This material has relatively good armor-piercing performance. Through a series of calculations, we have come to a conclusion: the armor-piercing depth of the enemy’s armor-piercing projectiles, when the angle of impact is zero degrees It is about [-]mm, and we have listed the table for the armor penetration depth at other angles."

As Luo Chaoying spoke, he handed a document to Lin Yuan. Lin Yuan took it over and looked it over, and said, "Our tank armor is very flat, and when the armor-piercing projectile hits it, the angle of attack is relatively small, so it will be destroyed by the enemy." Armor bullets penetrated!"

Ge Wenliang, a tank expert, said: "But if the armor angle of the tanks is improved, all these tanks will be returned to the factory, and our entire Seventh Division will have no tanks to use."

Xiao Yingwu, the commander of the Seventh Division, became anxious when he heard this, and said, "Old Ge, how can our tanks be returned to the factory? We should return all of them to the factory! Now that the war is imminent, our division does not have tanks, what can we use to fight?"

At this time, Lin Yuan smiled and said, "Old Xiao, don't worry, I've already thought about adding reactive armor to our tanks!"

Xiao Yingwu said: "Reactive armor? Do we have this thing now?"

Luo Chaoying said with a smile: "Why not? As soon as Comrade Xiaolin told me that the enemy used armor-piercing shells, I thought of reactive armor. This armor has explosives inside. When the armor-piercing shell hits it, it will detonate the explosives inside. The explosion would seriously disrupt the direction of the metal jet, weakening the jet and leaving the tank's armor intact."

"Thinking of the reactive armor, we started to actively prepare, and soon designed the preliminary data. We came this time to see what the armor-piercing level of the enemy's armor-piercing shells is, and then we can determine the amount of explosives. and types, and then produce and manufacture."

Xiao Yingwu said: "I hope these armors can be equipped with us as soon as possible."

Luo Chaoying said: "Don't worry, we have notified the Beijing ship, and now the first batch of reactive armor has started to be manufactured, and it will be shipped soon! Not only the reactive armor, but we have another good thing to give you .”

Xiao Yingwu hurriedly asked: "What good thing?"

Luo Chaoying took out a document and said: "This is the ballistic table we calculated based on the shape data of the rocket. From this table, we can see that if the enemy's rocket wants to achieve a hit rate of more than 80.00%, it must be at 200% or more. Shooting from a distance of about meters."

Xiao Yingwu said excitedly: "So that means, as long as we improve the coordination between infantry and tanks, it will be difficult for the enemy to have a chance to hit our tanks?"

Luo Chaoying smiled and said, "I'm not sure about this, you can ask Comrade Xiaolin."

Xiao Yingwu looked at Lin Yuan, who smiled and said, "You can say that."

Xiao Yingwu said: "Since we have reactive armor, we don't have to worry about heavy casualties. When can we launch an attack?"

Lin Yuan said: "Don't worry, just wait a moment, our army still needs to improve a lot, the first is the communication problem, we should increase communication channels between the superior and the superior, so that the situation that the superior and inferior cannot be communicated that night will not happen again , and to improve the exhaust pipes and cooling windows of the tanks, we will attack the Huaihe River Basin after crossing the Yellow River, there are many rivers in these places, our tanks cannot be turned off frequently.”

Ge Wenliang heard Lin Yuan's words and said: "We already have improvement plans for these. The communication aspect is easier to improve, and the exhaust pipe aspect is more time-consuming to improve, so we decided to adopt the method of batch improvement. 55 Didn’t the regiment and the 56th regiment have damaged tanks? We’ll take out the battalions with more damaged tanks and replace them with improved tanks. When the Yellow River is conquered, I guess the tanks will be replaced and we can use new tanks to fight gone."

Lin Yuan said: "Okay, let's go get busy." A few days later, on September 28, Lin Yuan received the news: the first batch of reactive armors had all arrived, and they are now preparing for the test at the test site. Yuan hurried to the test site, and heard a voice roaring from a distance: "Didn't I tell you to bring that thing? How did you forget?"

Lin Yuan was very surprised to hear this voice, because it was the voice of material expert Su Zhengming!Lin Yuan thought to himself: "Why is Mr. Su here? Why is he angry?" When Lin Yuan came up to see the person who was reprimanded by Su Zhengming, he was stunned in surprise.
