Chapter 165 Which one should I choose? (4k)

Lou Xiao'e hung on Gao Zhendong's neck and nodded repeatedly, causing Gao Zhendong to nod his head as well: "Yes, yes, yes, you do your work and I'll learn mine, hehe."

Lou's mother looked at her with both anger and amusement: "Shame on you."

Lou Xiao'e curled her lips, a smug look on her face, and then she giggled.

When Mr. and Mrs. Lou saw her expression, they also laughed.

The Lou family is very satisfied with Gao Zhendong. He has good conditions in all aspects, and his personality and ability to handle things are also very good. There is nothing to say about him to Lou Xiao'e and the Lou family.

The only thing is that I feel a little pitiful, being alone.

Putting aside this sad thing, this is not just half a son-in-law, he is a whole one.

After the matter was settled, Gao Zhendong and Lou Xiao'e stayed together for a while and then left Lou's house.

Lou Xiao'e chased out, stood on tiptoe, held Gao Zhendong's face, stamped a few big seals on it, then ran home giggling.

The next day, Gao Zhendong, feeling cheerful and happy, ran to the confidential room and sent out a confidential document.

As for the wedding, Gao Zhendong did what he said and left it to the Lou family to arrange.

Some equipment has already begun to be assembled and debugged in the single crystal furnace test laboratory, such as the power supply and part of the furnace body.

Some electric actuating mechanisms have also been delivered, but this part can only be assembled and debugged after the main furnace body is installed.

Yu Yuncheng, another silicon single crystal boss in the group, is also working very hard. There are many conditions here that he wants but does not have, and there is also a lot of new knowledge and theories, which is also a huge improvement for him.

The atmosphere of the entire research group is very good. Whenever a project progresses extremely smoothly, has a bright prospect, and everyone is looking forward to it, it is hard to find a few with a bad atmosphere.

Now Gao Zhendong is basically responsible for the principles, routes, initial design, and detailed design of some subsystems of his major. Other things will naturally be done properly by others. If they are stuck, they will come to Gao Zhendong to solve the problem.

This greatly freed up Gao Zhendong himself, allowing him to do other things.

In fact, this situation is very common. It is the operating mode of a normal and healthy scientific research team. From top to bottom, everyone performs their duties and contributes their own strength to a common direction.

Otherwise, how could Gao Zhendong have achieved so many results when he saw those scientific research giants in his previous life? Even though they may not have been in the project team for a long time and did not do much personally, the importance of their work may be much greater than those who are busy in the laboratory every day.

At the Grassland Tractor Factory, Mr. He quickly received Gao Zhendong's confidential documents.

In addition to being confidential, confidential channels are also extremely fast, which cannot be matched by ordinary communication channels.

When Mr. He opened it and saw that it was the Third Steel Rolling Mill, he was overjoyed. He had been looking forward to this thing for a long time.

It’s not that Mr. He relies on “waiting, relying on and asking” to get his work done, but since there is a clear and effective solution to a problem, wasting time and manpower on it is obviously a sign of mental illness.

The country is still very poor, and the little resources it has should not be wasted like this.

Mr. He excitedly opened the materials and read them carefully.

Although he had seen the table of contents of this book before, when he saw the actual content, he was still excited and shocked.

So complete!

I quickly flipped through the manuscript. The whole book starts with basic indicators and requirements. These indicators and requirements alone are what Mr. He and his colleagues did not fully consider when they considered the bismability of artillery in the past.

Director Gao is so talented!
When it comes to the theoretical analysis of the perturbation chain and then the determination of the model, parameters, identification, analysis, optimization and other contents of the drive chain based on the perturbation chain, Mr. He feels a little overwhelmed.

It’s not that I can’t accept it, but Director Gao really gave too much.

The whole book is full of various theories and formulas, which made Mr. He realize that he should not read the later part for the time being because he really couldn’t understand it for the time being. He should start with the simplest indicators and requirements at the front.

Fortunately, the second-generation tank has not yet been demonstrated, and there is still ample time for the entire research and development work. Otherwise, it would be a big hassle if we got the secret manual but couldn't produce any results because we couldn't understand it.

After reading the first part, Mr. He was already in a dilemma. Which of the three bistable systems should he use?
Hydraulic? Electro-hydraulic? Fully electric?
The three methods each have their own advantages and disadvantages, which made him feel conflicted.

However, he was open-minded and rough by nature, so he stopped hesitating after a while. I asked someone to let the boss worry about it.

It's not that he is unwilling to face the problem, but this thing is related to the route of the entire system, and it really needs the people above to confirm it.

To give a simple example, if I choose full electric drive, will there be any problem with the engine power?

I choose full liquid, will the car body be able to accommodate it?

Thinking of this, Mr. He collected Gao Zhendong's manuscript on the stabilization of the artillery system and went straight to find Mr. Luo.

"Boss Luo, I received the Shuangshuang book from Director Gao, but there is a problem."

In the circle of 5DL bosses at the Grassland Tractor Factory, when it comes to Director Gao, there is only one person: Director Gao Zhendong of the Beijing No. Rolling Mill.

Mr. Luo raised his eyebrows: "Why? Can't you solve the problem?"

"Yes! Of course I can. But there are so many ways to solve the problem, and it's hard for me to choose."

After that, he talked about the problems he encountered. After listening to Mr. He’s questions, Mr. Luo looked at the manuscript, waved his hand, and called for a meeting!
It’s not that they relied entirely on Gao Zhendong’s book without any accumulation. The 5DL originally had a vertical monostable, but after seeing more possibilities in the book, the original driving principle of the vertical monostable was not so attractive.

Soon, several subsystem managers gathered in Mr. Luo’s office.

Knowing that this small meeting was held for Mr. He's matter, the general manager in charge of mobility said with a smile: "Mr. He, you have recently received foreign aid, and you are very proud of yourself. This is not good for you." Mr. He laughed: "Yes, yes, I mainly have too many things to choose from, so please help me."

If he behaved like this a few decades later, I guess everyone would start scolding him, saying, "You are so Versailles, Lao He."

After everyone arrived, General He repeated his question and finally said, "Comrades, this is the situation. My question now is, when conducting preliminary research on the bistable system of the next generation of tanks, which one should be selected: all-hydraulic, electro-hydraulic, or all-electric."

The man in charge of mobility laughed and scolded when he heard this: "Fuck, I don't have any idea of ​​getting full liquid here, but you are still dissatisfied with getting full liquid here."

The travel and suspension system is different from the bistable system. The "three-liquid" system composed of hydro-pneumatic suspension, hydraulic transmission and hydraulic control is the highest goal of the current travel and suspension system. It is a top technical problem that can only be thought about but is difficult to achieve. Even after 20 or 30 years, it has not been completely solved.

Fortunately, these "three liquids" are essentially the icing on the cake. Without them, several core elements of the tank can be achieved.

Mr. He smiled and said, "My requirements here are low."

The CEO in charge of mobility thought about it and started talking about business: "To be honest, power is not a problem for my engine. It uses hydraulic drive and still needs a power pack to provide power. No matter which system is used, the power difference is not that big. It's just that the output means are different."

Mr. Guan didn't say anything. This matter had little to do with his protection here for the time being.

The boss in charge of the vehicle body had something to say: "If it is all hydraulic, it will indeed have some impact on the layout of the space inside the vehicle. The advantage of all hydraulic is that the technology is simple and reliable, but there are certain problems with noise, efficiency, heat dissipation, maintainability and maintenance costs. Leaving enough maintenance space for the hydraulic device in the vehicle body is actually a hassle in itself."

Speaking of this, General Guan is no longer sleepy: "Another problem with full liquid is that it is easy to catch fire after battle damage, and the secondary effect is not low. Although with the help of Director Gao, there has been a breakthrough in the fire extinguishing and explosion suppression system, we can't rely entirely on this thing."

Well, they also helped with fire extinguishing and explosion suppression, but the issue that everyone is discussing here is that they helped a little too thoroughly.

Mr. Luo thought for a moment and asked Mr. He, "What do you think?"

Mr. He smiled broadly: "Of course, my own idea is to make full electric drive, and Director Gao's manuscript also contains a lot of design principles and schematic diagrams of full electric drive components."

Mr. Luo smiled and said, "Director Gao's major is automation, and he is more inclined to electrical automation, so it's not surprising that the examples use electricity."

The CEO of the mobile phone company sighed: "They even designed a practical example for you? In my opinion, Lao He, you should just go all the way and make a fully electric drive."

Mr. Guan also nodded: "I have the same idea. With full electric drive, there is no secondary effect. It will be much simpler for me to protect myself. I don't have to consider the secondary effect problem caused by the hydraulic drive of the bistable system."

The body also thinks this direction is good: "If it is all-electric, the size of the motor and the actuator should be much smaller, the overall layout will be much simpler, and the efficiency of all-electric drive is much higher than hydraulic."

When Mr. Luo heard that everyone had the same opinion, he wondered what was there to worry about.
He turned to Mr. He and said, "Everyone agrees with this. You may also be inclined to this. So what are you worried about?"

Mr. He did not hesitate: "The technology of full electric drive is difficult and the reliability is low. According to my existing technical means, I can only use analog acquisition and control for full electric drive. However, in harsh environments, the analog system has serious temperature drift, component performance is inherently inconsistent, and acquisition and transmission are difficult, which will cause a lot of trouble."

"For example, the accuracy of adjustment control is poor, the consistency between vehicles is poor, which makes production and debugging complicated, and slightly more complex control methods are difficult to implement, etc."

Hearing this, Mr. Luo was curious: "Since there are so many problems, why does Director Gao's book still tend to favor full electric drive?"

"Because Director Gao's entire set of technical routes can be more accurately implemented using electronic control, unlike my derivation and design based on empirical methods, Director Gao's work uses mathematical formulas for modeling, derivation, and design. Therefore, his results can guide both full hydraulics and electro-hydraulics, but they are naturally more compatible with electronic control."

After Mr. He finished speaking, he added: "To be honest, there are many things in the back of this book that I cannot understand for the time being. It requires a certain level of advanced mathematics."

Mr. Luo sighed: "He is a genius, but too genius."

Just when everyone was hesitating, Mr. Guan, who had first dealt with Gao Zhendong, asked a question: "Old He, do you think that with Director Gao's style, he would come up with a technical route that you cannot implement or is full of flaws?"

When Mr. He heard this, his eyes lit up. It had to be Lao Guan. He was the first one to come into contact with Director Gao, and he was also the one who was most familiar with Director Gao's style.

Mr. Luo nodded. "Yes, Director Gao's style is usually to try to be simple and direct, to solve problems in principle, and he has never proposed a completely unrealistic approach without a practical basis."

The mobile boss also agreed: "That makes sense. Even though he is the least familiar with the power part, the power package concept he proposed is based on existing technical conditions."

Mr. He thought for a moment and said, "Actually, the entire route has been explained very clearly here. It's just that my own technical ability is limited. I'm ashamed of myself."

Mr. Luo shook his head: "Maybe it's because, in his opinion, what you lack is not just the category of tank gun stability, so he didn't mention it here. Or, he thought you knew it."

After saying this, the others couldn't help but burst into laughter.

When Mr. He heard this, he thought it made sense, so he decided to cut off the source of the problem: "Look, why am I hesitating here? Why don't we just ask Director Gao to come over? Mr. Luo, what do you think?"

"Yeah, that makes sense. If possible, you should ask him to come over and take a look at the situation, and then give you some suggestions or solutions based on the conditions you have. That would be the best. Besides, since you have troubled him so much, you should also ask Director Gao to come over as a guest, haha."

When Mr. He heard this, he immediately took action: "Then I'll call him and ask him to come over."

Mr. Luo stopped him: "I'm afraid you can't invite him. It's not that he's arrogant, but I'm afraid he has important work that never stops. If you invite him, it will be difficult for Director Gao to coordinate and handle the work he has on hand."

"Ah, what should I do?"

Mr. Luo stretched out a finger and pointed to the top of his head: "We will ask the Defense Work Committee to coordinate and invite him, and the Defense Work Committee will contact the 17th Ministry of Machine Building. In this way, once the trip is made, Director Gao will not have to coordinate his time with all parties related to his work, and it will also show that we value him."

Several people thought that Mr. Luo’s idea was good, and the matter was decided.

The leader of the Defense Work Committee was not surprised when he received the call for help from the Grassland Tractor Factory. He was also aware of Gao Zhendong's achievements and accomplishments in this area. After all, he had attended more than one meeting related to Gao Zhendong recently.

Not to mention the infantry fighting vehicle that he and Gao Zhendong worked together to promote.

"Well, your idea is good. Comrade Gao Zhendong may be young, but you can put aside your pride and age issues and take the initiative to ask for advice. That's great. This is the attitude of seeking truth from facts to solve problems. I will handle this matter."
