However, Zakharov was ecstatic and ecstatic, but on the surface he maintained a rare reserve: "It's not good......

"There's nothing bad about it, I'm a person who doesn't like trouble, okay, stop talking nonsense, do you want to know? If you don't want to, I don't have much time right now! ”

Without waiting for Zakharov to finish speaking, Bai Yi waved his hand impatiently, rudely interrupting Zakharov's words, with a very impatient look on his face, as if all the troubles in the world were his fierce enemies, Zakharov dared to say a second sentence when he saw this situation, and quickly said with a sneering face: "Listen to you, listen to you, as long as you can tell me the core technology of the additional armor, you can do whatever you want!" ”

"Okay, you remember, this set of additional armor is actually not complicated......"

So Bai Yi began to talk endlessly about the specific technology in the additional armor on the improved T-34\85 tank, as he said, the principle is actually very simple, nothing more than a steel plate made of a 180mm box, and the front and back sides use 20mm thick steel plates.

The interior is welded into a "Z" frame with several 5mm thin plates, and the remaining space is filled with polyurethane, so that an additional piece of armor with strong defense against armor-piercing bullets is made.

When the high-speed metal jet breaks through the outer 20mm steel plate, the huge impact force will deform or even shatter the Z-shaped steel plate inside, and the high temperature of the metal jet will melt the polyurethane filler at the same time.

It is quickly fused with the deformed and cracked thin steel plate to form a mixture with a sharp change in density, so that the metal jet diverges due to the change of material density during propulsion, and the neutralization of the high-temperature substance by the polyurethane filler finally completes the purpose of preventing the metal jet from invading!

“…… Therefore, the black smoke rising from the tank just now was not the result of the internal damage caused by the tank being penetrated, but the polyurethane filling was melted at high temperature! ”

"I see!"

Zakharov nodded, but then looked at the words he had just written in the small notebook he carried, frowned, and then used the pen in his hand to mark a few phrases, then raised his head again and asked Bai Yi: "I can still understand the structure you just said, but what is this polyurethane filler?" Isn't it hard to obtain? ”

The chemical term polyurethane filler is so lofty that Major Zakharov, who can understand all Bai Yi's descriptions of the structure of the additional armor, is at a loss for this unpopular phrase is the second monk, and subconsciously feels that this is a great substance, otherwise how could he resist the power of the armor-piercing bullet?

Don't say it's him, even Bai Yi in his previous life was also confused when he first heard the teacher say this professional phrase in class.

However, fortunately, Bai Yi was diligent and studious, and finally found the source of such special nouns in the manual of a well-known family planning supplies, so he glanced at Zakharov so calmly: "It's hard to get?" Let me tell you the truth, among the supplies rationed by the Soviet army to you are polyurethane products! ”

"Won't it?"

"If you don't believe it, go back and see if the instructions for the family planning supplies specially provided for your school-level officers are made of polyurethane!"

"Huh?"

Hearing this, Zakharov couldn't help but be shocked, he never expected that that kind of shy little thing could have such a big effect, not only to block the man's strong secretions, but also to resist the invasion of metal jets, it is really a must-have for home travel!

"Don't make a fuss, it's good that you know it yourself, if you really say it, it's worthless!"

Just when Zakharov was stunned, Bai Yi's meaningful words came to his ears lightly, making Zakharov stunned, and then his dark gray eyes gradually deepened.

That's right, such a simple structure, such readily available materials, but can create an unparalleled defensive effect against armor-piercing bullets, it is indeed worthless to say it, but if he doesn't say it......

At this moment, Zakharov seemed to see countless honors surging towards him, and under the agitation of his mood, the corners of his mouth involuntarily pulled frequently, revealing a smile that was difficult to suppress in his heart......

Bai Yi said that Major Zakharov had been completely caught up in the brilliant achievements of the future, so he didn't say anything, and walked away quietly, but when he was about to come to the modified T-34\85 tank, he found his old friend Chen Yaoyang reclining on the tank, looking at him with a smile.

They are all old brothers who were born and died together back then, and they have long been familiar with each other, because of this, as soon as he saw Chen Yaoyang's expression, Bai Yi knew what was going on, so he took out a cigarette and lit it by himself, and threw the seized American cigarettes to Chen Yaoyang: "Is it Zhang Huangxin's mouthy guy chewing the root of your tongue with you again?" ”

"You just burn high incense!" Chen Yaoyang was not polite, took the cigarette and alcohol and took out a cigarette and lit it, and then put the excess into his jacket pocket, and then continued: "Thanks to Zhang Huangxin, if someone else had heard you hand over so many core technologies to outsiders, he would have stabbed you to your superiors a long time ago, and he told me that he also wanted me to persuade you not to take military regulations too seriously!" ”

"Then why don't you persuade?"

"You dig holes for people, do you say that it is useful for me to persuade you?"

"I said Lao Chen, can't you think of me better?" Bai Yi listened to Chen Yaoyang's words, and immediately called out to the sky: "He strongly asked me to give him the technology of additional armor, and I also talked about it exactly according to the technical principle of our current additional armor."

The conscience of heaven and earth, Lao Chen, but technically speaking, I want to have half a lie, and I will suffer a big loss if I don't ask the Soviets for technology transfer, and you still say that I dig a pit? I'm really more wronged than Dou E! ”

"Yes, yes, yes...... You are telling the truth, but it is also a big pit of telling the truth, otherwise why don't you take out the blasting reactive armor that our factory is developing and share it with others, but you just say that a temporary top cylinder of emergency goods is out of the blue, I now have a very strong premonition, the Soviet Union will not get it right, it will go to the black on the special rubber additional armor! ”

Chen Yaoyang was not only not confused by Bai Yi's collision with the sky, but threw Bai Yi a big roll of his eyes without a good voice: "Also, our polyurethane filler obviously uses a doctor's surgical gloves, but you just told people what kind of family planning supplies are used, and you said that you dug this pit without damage?" ”
