"Although Zheng Yucheng usually likes to mess around, I don't think it's possible in this matter. They have this mind, it is impossible not to be prepared, Pakistanis are not so easy to fool, if they don't figure it out, they will give money?" Long Yaohua shook his head.

They know Zheng Yucheng very well as a person.

If you are not sure, Zheng Yucheng will not fool around, not to mention that it is also related to the diplomatic relations between the two countries.

If something goes wrong, no one can afford the consequences.

"Hopefully, but we can't say too much about it now, let's wait until 617 talks to the Pakistanis. Li Mingshan decided to wait for now.

Zheng Yucheng did not seek them, nor did he ask 404 to talk to the Pakistanis.

"But you have to keep an eye on them, in case he is not honest, he will be in trouble. Long Yaohua said, "He said that he came here for the excavator, and he came too early." ”

Because of understanding, we can connect things that are not originally related.

Long Yaohua did not tell Li Mingshan that the person Zheng Yucheng sent to Xiangjiang was Xie Kai.

Xie Kai was too impressed by Long Yaohua.

He couldn't refute the reasons given by Zheng Yucheng, Xie Kai for the future of the little friends who grew up together, Long Yaohua always felt that things would not be so simple. That kind of thing, with Zheng Yucheng's energy, just find another unit to solve it.

The only thing he couldn't figure out was where Zheng Yucheng knew the information that Pakistanis were transiting through Xiangjiang.

The intelligence officers of the military also learned about it later.

Coincidental?

Long Yaohua doesn't believe in coincidences.

"Director Zheng, didn't you say that you brought experts over?" When Zheng Yucheng arrived at the 201 Institute, he only took Xie Kai, Fang Xianglin and Wang Xingqiao, no matter how they looked, the children around Zheng Yucheng did not look like experts who knew technology.

A kid is a joke if he's an expert.

Zheng Yucheng pointed at Xie Kai and introduced to the two, "Don't underestimate him, he understands the fire control system very clearly." ”

"Director Fang is good, Mr. Wang is good. Xie Kai greeted the two generously.

Zheng Yucheng is bragging more and more now, doesn't he know that his age is a hard injury?

"Director Zheng is joking, the schematic diagram of the fire control system he provided was designed by my father for more than ten years, he is just a theoretical party, and has never experimented, I have been interested in these since I was a child, so I know a little bit. ”

In front of Wang Xingqiao, Xie Kai didn't dare to pretend to be forced.

Who is Wang Xingqiao?

The father of China's fire control, just saw the simple technical principles of foreign countries and a little information without any parameters, and felt that it could be copied. Then I went back to discuss with my daughter-in-law, and the husband and wife worked together to polish the lenses by hand, distribute the light path, and without any foundation and sufficient resources, they came up with a stable image fire control system that is standard on the third-generation tank.

Before being so good, Xie Kai dared to pretend to be forced?

That's definitely not a matter of being struck by lightning.

"The lad was humble. Wang Xingqiao frowned and looked at Xie Kai, Fang Xianglin felt that for the sake of funds, he couldn't offend Zheng Yucheng, and he still had to give face.

It is difficult for them to ask for hundreds of thousands, as soon as Zheng Yucheng comes up, he directly smashes two million, how can he offend such a gold owner.

"Tell me what you're asking for. Wang Xingqiao went straight to the point, as long as it wasn't too much, you could consider it.

An image-stabilized fire control system had to be developed.

"Actually, there are no requirements, I know that Mr. Wang is engaged in a lower anti-stabilized image fire control system without a follow-up system. This kind of system is simple, high reliability, low cost, mechanical synchronization, can work without the use of power supply, can also be downgraded to manual watch work, no need to set up a separate auxiliary sight......" Xie Kai said the advantages of the lower anti-stabilized fire control system.

was interrupted by Wang Xingqiao, "Little comrade, it seems that you have a clear understanding of the advantages of this system, so you should talk about the shortcomings." ”

They know that when the other party talks about the advantages, it must be to pave the way for the sake of talking about the shortcomings.

Zheng Yucheng, an old fox, actually used a child to hit them.

"Mr. Wang, I don't know if the fire control system you are studying now can accurately target the people at high speeds?" Xie Kai nodded.

Just this sentence immediately made Wang Xingqiao's face embarrassed.

Fang Xianglin was even more dumbfounded.

This is the biggest drawback of the system they studied.

It seems that it can be fired during the march, because the mirror assembly is rigidly connected to the gyroscope and there is no stabilization device, so the accuracy is relatively high when the bump amplitude is not large during the tank march.

However, in the process of traveling in the off-road field, the body of the vehicle is bumpy, and the accuracy of the lower anti-stabilized image fire control system with poor anti-interference performance is very poor.

"Why can't you!" Wang Xingqiao looked at Xie Kai and said with a red face.

He did not deny the flaws of his work.

"We need a fire control system that allows third-generation tanks to accurately hit targets during high-speed travel in complex terrain. Xie Kai said.

Since you know Wang Xingqiao, it is naturally clear that Wang Xingqiao is very uninterested in the anti-anti system.

Xie Kai did not know whether it was because of the inability of the follow-up system that made the father of China's fire control uninterested in such a complex system as the anti-Japanese system at first.

It was not until the last Type 99 main battle tank that the optical channel capacity of the upper and lower anti-aircraft systems was small and could not provide conditions for the use of artillery-launched missiles and thermal imagers, so it had to start researching the upper anti-counter.

Mr. Zhu, who served as the chief designer of Type 99, chose the lower anti-stabilized fire control system from the beginning, not considering the problem of stabilizing the image or not, but the fact that the use of this system can be operated without relying on electricity, and the imported British disturbance fire control system is not good.

At present, the project of the third generation tank has been established, and the initial technical scheme demonstration is being carried out.

"The system I studied can provide accurate shooting ...... on the move," Mr. Wang said angrily, very unhappy with a child questioning himself. "Because there is no follow-up system, there are fewer factors that produce errors, and the sight eyepiece follows the barrel swing, which is more suitable for use in potholes. ”

Xie Kai patted his head, and the information he saw on the Internet was actually true.

Mr. Wang is not interested in the upper anti-stabilized image fire control system.

That's a no-brainer.

The question is, how can he convince Mr. Wang now.

"Mr. Wang, can you tell us about the structure of your system?" Xie Kai did not ask a direct question, but decided to take a roundabout route.

It is not easy to convince Mr. Wang.

Only if the technology succeeds, they will be able to take down the fire control system of the three generations of tanks.

It is not only Mr. Wang who needs to be convinced, but also Mr. Zhu, the third-generation tank commander, after all, what Mr. Zhu needs is a system that can run without electricity.

Yesterday, Zheng Yucheng reminded that the 201 Institute was naturally prepared.

Wang Xingqiao pasted the structural principle drawings on the blackboard and introduced the working principle of the system.

This is no different from what Xie Kai understands, Zheng Yucheng is in a fog, he can't figure out these things at all.

"According to Mr. Wang's introduction, when the tank gun is pitched, the scope body is driven to swing synchronously with respect to the turret through the four-link mechanism installed inside, while the shooter cannot move up and down......"

"Mr. Wang, what we need is the most advanced third-generation tank fire control system. Xie Kai reminded, "The mechanical follow-up system, the night vision instruments such as low-light and thermal imaging required for night battles are concentrated in the sight, how to ensure stability?"

Xie Kai raised his own questions about the entire system.

Wang Xingqiao originally thought that Xie Kai was a child and couldn't know too much.

He has always believed that the lower anti-stabilized image fire control system is the most suitable for use.

The questions raised by Xie Kai were all to the point.

"At the moment, the most suitable system for us is this kind of system, which is simple in structure, low cost, can provide high accuracy, and increase the starting hit rate. Fang Xianglin said, "At present, there is no unit research on the follower system, and it cannot be produced in China, and it is impossible to introduce it from abroad." ”

"That's true, on the set of drawings we provided, there is a follow-up system solution. Zheng Yucheng was very satisfied with the shock of 201 to Xie Kai.

He didn't even know what a follow-up system was, but he wasn't questioned.

"The principle of the follower system is simple, but the requirements for the whole system are very high. Not only measurement technology, but also control technology, and even the data computing performance of the computer have strict requirements. Mr. Wang reminded Zheng Yucheng. "There is no need for a follow-up system, although the performance is slightly worse, I think this is in line with the development of China. If you equip the anti-system, just a follow-up system, it will cost hundreds of thousands!"

When Xie Kai heard this, he immediately understood.

It's not that Mr. Wang doesn't want to do it, but he doesn't have money, and it's too difficult.

In addition, the cost of building it is too high for the military to afford it, so it is better to build a lower-cost anti-anti-epidemic system than that.

"We can afford to pay for this research!" Zheng Yucheng said proudly, "You don't have to worry about money." ”

He now has money in his hands, so he naturally speaks hard.

"It's not a question of money, the key issue is the user, without a user, it's a waste to get it out and no one uses it. Wang Xingqiao shook his head, Zheng Yucheng didn't understand the situation at all.

"What if there are users?" Xie Kai was also aware of the other party's concerns.

This is the same idea as Marshal of the Soviet Union Ustinov, very simple.

Weapons and equipment should be developed, easy to manufacture, suitable for mass production, and cheap.

"Advanced performance and low price are not linked at all. This is also a problem that countries around the world are currently facing. The better the performance, the more widely new technologies and materials will be used. The 59 tank is cheap, but it can't compete with the advanced tanks. Otherwise, there would be no need for us to engage in more expensive and advanced tanks. Xie Kai said. "Of course, at the moment we can get the bottom out first, and that's enough for our customers. ”

Pakistanis don't care too much about it anyway.

It's too expensive, and they can't afford it.

"Well, let's improve the research work of the anti-system first, and then talk about it after the test, how about it?" asked Zheng Yucheng.

There is no point in continuing the argument.

"Xie Kai, what if the Pakistanis reach an agreement with 617?" Zheng Yucheng asked Xie Kai on the way back, "I'm a little worried, if it doesn't have our business, it will be troublesome." "Mobile phone users, please browse and read, a better reading experience.
