If compared with the tanks of Han, the T-72 is enough. The 96 tanks developed back then were based on the T-72. They were light weight and seemed to be a good choice.

However, in Qin Guan's mind, he is more inclined to use Leopard-2 for development, which can carry more weight, which means that there is a greater development prospect.

However, this is definitely not just a few words from Qin Guan. The selection of tanks is of great importance and must be cautious. Even the 125mm gun that Qin Guan has insisted on is no longer insisted, only after comparison. After that, it can be determined!

Therefore, Qin Guan started to get a Leopard-2 prototype, and this suggestion made Old Zhu frown again.

My side hopes to get a sample car, but the people from Hans Country are unwilling. If you want to buy it, you can buy a few hundred cars.

"I wish, the people from Hansi are here again, and I hope to meet with us immediately." Just then, an assistant hurried over and said.

The people from Hans Kingdom are here again. It must have been when they returned, and found that they couldn't make the ceramic armor anyway. This time, they came to find fault.

Both sides have left behind. According to the agreement, the people of Hansland should export their engine equipment to their own. But until now, some key equipment is still in the foreseeable future. For example, for an engine, the most The key high-pressure oil pump requires high-precision processing equipment, and these equipment have not been seen.

Therefore, the company wants to mass-produce the most critical 1500 horsepower engine, and it has become a bubble. Hans has promised to temporarily export to its own high-pressure oil pumps, but in this case, it will be stuck by Hans.

Now, the Hans people come to find the fault.

"Okay, we'll go right away." Zhu Lao said, after finishing speaking, he looked at Qin Guan again, and stopped talking.

"I'll go with you, if possible," Qin Guan said.

This is what I mean by Zhu Lao. People from Hans are more difficult to deal with than people from Niu, especially Heinz.

The group of people came to the meeting room, and the Hans nationals who had been waiting there had already begun to attack.

"Liar, you are all liars." Heinz roared: "The products we make using the technical information you provide can not achieve the effect of samples anyway!"

Nonsense, of course it can't be achieved. As long as the process inside is slightly changed, such as a slight increase in temperature and an increase in the content of a certain substance, the properties of the finished product will change greatly.

If you succeed in doing it once, then the equipment that we have already paid for precious foreign exchange will probably never come. This is how the merchants are, and all they make are black-hearted money.

"Really?" Qin Guan asked, sitting next to Zhu Lao, "Then you are really stupid. With the craftsmanship and technical information, you still can't produce it."

"What?" Heinz was immediately angry: "Who are you? Come here to ridicule us?"

During the negotiations a few days ago, I have never met this young man. Seeing him sitting next to Zhu Lao, is it Zhu Lao’s deputy? So young, it's not like it!

"My name is Qin Guan, an armor development expert." Qin Guan said without shame: "Our country is at the world's advanced level in armor development."

"That can't fool us, there must be a problem with that craft!" Hans is not a fool, and soon realized the problem, which is probably the problem with the craft.

"There is a problem with our craftsmanship? Then what do you say is the problem?" Qin Guan confronted **** for tat.

What is the problem? I want to know, we will improve ourselves! It must be your hands and feet!

Wait, could it be the hands and feet of Niu people?

Heinz suddenly thought of another possibility.

"Huh, in short, if we don't make things clear today, we have to suspend the introduction of our high-horsepower diesel engine equipment!" Heinz said, this is where their confidence lies.

The Han state urgently needs high-horsepower engine technology, which is exchanged for armor technology. Since the armor technology is fake, the introduction of high-horsepower engine technology will end here.

Anyway, Han Guo has already paid the full amount of the equipment, but it will not refund then.

"Really?" Qin Guan continued: "Is this a plan to unilaterally tear up the agreement? It's a pity. Originally, we had two new tank armor technologies and planned to provide them to you. Now, forget it. "

New armor technology? Heinz's heart was overjoyed, the Han people actually have good things? Although he was very happy in his heart, he showed disbelief on his face: "Don't want to continue fooling us, we will not be fooled!"

"Yeah, what new armor technology, are you talking about it?" said a Hans State technician next to it.

"We all know that by simply relying on head-to-head, tank armor protection is always limited. If we want to continue to improve armor protection capabilities, we must start with new principles." Qin Guan said: "Now, we have two new ones. Theory of armor protection."

Qin watched the eyes of the guys opposite, knowing that he was attracted to them again. Yes, now that he wants to improve his protection, he must improve on the principle.

"The first one is to restrain the armor." Qin Guan took out a piece of paper and gestured on it: "Our composite armor is not a single piece. It is made of metal materials such as hexagons and octagons. A constraining ring divides the armored ceramics into one small grid and one small grid. The grids are next to each other, just like our hexagonal public toilet floor tiles."

Qin Guan quickly drew this pattern. The biggest feature of restrained armor is that it can restrain, there are so-called restraining rings.

"What's the benefit of this?" someone on the other side asked.

"In this way, when the armor-piercing projectile and the armor-piercing jet hit the ceramic, the fragmented ceramic pieces and powder will be squeezed inward by the confinement ring and fly out in the opposite direction of the armor-piercing projectile or jet, hitting the core or jet, improving Protection ability."

The current first-generation Chobham armor does not have such a restraining ring, which is directly stacked together.

"After this improvement, on the original basis, at least 10% additional protection can be provided." Qin Guan continued.

With the gradual maturity of the material application, the key to improving the protective power in the next step is to start with the structure. The use of aluminum confinement rings, a small modification, can make the protective power a new improvement.

Sure enough, Qin Guan's proposal attracted the Hans people on the opposite side, and the armor experts who accompanied him immediately muttered quietly.

Qin Guan smiled, even if he didn't use the system, he still had an advantage.
