Chapter 168 Journey to the Grassland [2] (4k)
Then he raised another question that he was very concerned about: "Director Zhendong, since digital circuits are used, the control core cannot continue to use analog circuits. OK, how do we solve this now?"
The two of them had been in contact for a long time, and he still used to call him "Director Zhendong."
Gao Zhendong thought for a while: "I suggest that it be a principle prototype. You can first test it on the DJS-59 and use the DJS-59 as the control computer. It is not only the bi-stable artillery, but also the fire control related to it. You can also connect it to DJS-59.”
When Mr. He heard this, hey, this is a good idea.
Numbers, numbers, what is the best at processing numbers, of course it is a computer.
And in this way, gun stabilization and fire control can be cross-linked to form an integrated fire control system. These two things are born from the same family. When cross-linked, there is no better way to greatly improve fire response. Speed, accuracy, and reduce the number of operations of the crew, simplifying the sighting and firing process.
“Okay, let’s do it! But”
Gao Zhendong smiled: “But what?”
“But isn’t DJS-59 too big? Point? And the price is not cheap, and the production volume may not keep up. Once the tank is finalized, it is not a matter of hundreds, but thousands.”
In fact, the production quantity of all improved models of 5DL is as high as more than 10,000 units. With the current size and price of DJS-59, it is obviously inappropriate.
Gao Zhendong smiled mysteriously: "You study like this first, it will take a long time."
After that, he put forward the bistable suggestion: "Mr. He, the bistable configuration In terms of selection, my suggestion is to walk on two legs in the pre-research stage."
"Walking on two legs?"
"Yes, both full fluid and full electric. It has many disadvantages, but it is simple and very reliable. The technical risk is low, and the cost is relatively low. It is not difficult to build. It can be used as a backup. All-electric has many benefits, but the technology is immature and the technical risk is high. It can be used as a backup. To study the target system. If managed properly, the overall cost of walking on two legs is not much higher than that of all-electricity alone.”
"Moreover, it is not a waste to make the whole liquid, and it has potential value for civilian use. As for the electro-hydraulic, I want to dip both ends, but both ends are not relied on, so it is not recommended."
This suggestion, in fact, is From the situation of aircraft carrier catapults that Gao Zhendong saw in his previous life, both steam and electromagnetism were really being worked on at that time. Electromagnetism was the target and steam was the backup. In other words, conversely, electromagnetism was just a possibility that we were striving to pursue, and steam was the realistic choice. .
But everyone knows what happened later. Our "Magnetic King" made a breakthrough in electromagnetic catapult technology and put it into practical use. The electromagnetic catapult was finally put on the ship.
Mr. He thought for a moment: "Well, Director Zhendong, what you said makes sense. This matter can be discussed in a meeting. You are the deputy chief engineer and I am the artillery commander. It should be okay for us to raise this matter together. There will be a meeting soon."
Gao Zhendong nodded: "Well, that's okay."
After talking about this, Gao Zhendong remembered about digital circuits, so he promoted his book.
"Mr. He, regarding the basic issues of digital circuits, you can find someone in Beijing to find a book, "Logic Operations and Design of Digital Circuits", published by Machinery Press. It contains numbers. You can learn some basic knowledge about circuits first.”
Mr. He was very happy to hear that there were basic books on digital circuits available for purchase, and he quickly agreed to call someone to arrange them.
While asking someone to arrange it, he smiled and said: "Hey, Director Zhendong, why didn't you tell me earlier that you had this book, or bring it to me by the way, so I wouldn't be laughed at by Lao Luo? "
Gao Zhendong said with a smile: "This is a book compiled from the training content I received when I was working on computer design at the Computing Institute. If I recommend my own book to others, there is always something wrong with it. Sorry.”
When Mr. He heard that this book was also written by Gao Zhendong, he didn't know how to praise it for a moment. He opened his mouth and simply laughed together with Gao Zhendong.
The two of them, together with other researchers from Cannon Shuangstable, had this meeting until the evening, and they all had dinner in the conference room.
After final discussion, a set of artillery bi-stable research plans were formed.
Mr. He looked at the dense meeting minutes and said with a smile: "Today is a great harvest. Director Zhendong, I asked the boys to sort out today's meeting minutes and form a preliminary plan. I will bring you tomorrow Take a look at our actual situation. After you finish reading it, I guess the boys will have a rough draft of the plan. You can revise the plan based on the inspection, and then we will put it forward."
The arrangement was very compact and organized, and Gao Zhendong agreed.
So the people who had been busy for most of the day separated, and Mr. He personally sent Gao Zhendong to the guest house of the Grassland Tractor Factory before returning.
The next day, Mr. He took Gao Zhendong to inspect the situation at the Prairie Tractor Factory. When they arrived at the shooting range, they saw people preparing to do armor-related tests. Gao Zhendong's eyes lit up. A man's romance is an explosion.
He turned his head and smiled at Mr. He: "Well, Mr. He, if it's convenient, can you let me fire two cannons during the test? Hehe, I fired a lot of guns on the battlefield. I’ve never played before.”
When Mr. He heard this, he couldn’t help but laugh. At this time, Gao Zhendong made him feel like a young man.
"Haha, of course there is no problem. These armors and bullets are basically your achievements. It is perfect for you to test them yourself."
So Gao Zhendong spent half an hour and had a good time. Well, this was getting familiar with the operation of the equipment, and it could be considered part of the inspection.
It took a day for Gao Zhendong to have a basic understanding of the Prairie Tractor Factory and the related technical conditions. Then what he did was not to rush to modify the materials for the meeting, but to work with Mr. He to pull together all the The dual-stable comrade took his own manuscript on artillery stabilization and taught the comrades a lesson.
Although time is limited, the content and core key points can still be explained to comrades, especially the large number of formulas and theories in it, which really need Gao Zhendong to explain.
This book uses mathematical modeling from the bottom up to guide design methods and theories, which is a completely new field for the research group that currently mainly relies on experience for design. Fortunately, Gao Zhendong has a good mind. During the process of copying the book, he first integrated the entire book and studied it himself. Otherwise, he would never be able to explain it now.
Overall, everyone’s feeling is: it’s very professional, difficult, but very rewarding.
Different from the previous designs where the design was quite confusing and relied heavily on guesswork. When there was a problem, the pain started to be solved. This theory at least starts from the most basic mechanical analysis. Based on physical knowledge, a complete set of mathematical models was established.
To put it awkwardly, I used to rely on copying, and then in the process of copying, I would see if I could make some changes and come up with something suitable.
A lot of the development of early equipment is like this. If there is a prototype, it can basically be produced. After all, our scientific and technical personnel are very hardworking and diligent, and they are not stupid. But if there is no prototype, then it is probably It's going to take a long time.
As important as Big Mushroom, it can gather the top bosses in the country, and of course the effect is very good.
But now there are many industries waiting to flourish. With so many projects, where can so many top tycoons use them? They still have to rely on grassroots scientific and technological workers, and what grassroots workers lack most is theoretical guidance.
Now for bistable designers, they can calculate first, calculate the theory clearly, establish a good model, and then start the actual design.
Based on the design parameters and related indicators, first establish a model, and then determine the working parameters and related equipment selection based on the model results. If you determine any problems encountered during the design process, you can also get a certain degree of guidance based on the model< br>
In the past, it was not even possible to "know what is happening", but through this set of theories, it is possible to "know what is happening" to a certain extent. This is undoubtedly useful for the design of bistable systems. A huge leap forward.
For Mr. He, whether to choose full liquid or all electric, he doesn’t care for the moment. He has to get through this set of things quickly. After all, whether it is full liquid or full electric, he can get it first. With the support of this theory, it would be much easier to do.
After the first day of class, Mr. He sighed to Gao Zhendong: "Director Gao, it would be great if you could stay in our factory. This theory is still a bit difficult. In just these few days, I can't even do some mathematics." We can’t even master the tools.”
But he also knew that Gao Zhendong had tried his best. Gao Zhendong was also very busy with his own work, and it was impossible to stay at the Prairie Tractor Factory for this matter. The root of the matter was still there. The existing technical strength is weak, and there is no advanced theory, but it cannot be mastered in a short time.
Gao Zhendong thought for a while and said: "Mr. He, may I make a suggestion?"
Mr. He was overjoyed: "Okay, Vice President Gao, please tell me." In his opinion, this At that time, Gao Zhendong was the deputy chief engineer of the tank research project.
"Can you select a few people with excellent mathematical skills to stay in the capital for a period of time, live in the guest house of our steel rolling mill, and eat in our canteen. They usually study by themselves, and I will take some money every week Give them time to answer their questions and solve the problems they encounter in their studies. The cost of food and accommodation in our factory is not high and it is close to me. In this way, their learning progress will be faster. ”
< br>
Mr. He thought, yes, if the mountain doesn't come, just let me come. If I come, it will be fine if the mountain doesn't come: "Hey, that's right, Director Gao, why didn't I think of this idea? During their study period, our side I also learned, and at the same time, I used my original experience to do pre-research on the full-liquid drive. After everyone has digested it, I combined the full-liquid experience with this theory and the examples in it, and then I went back to the all-electric drive, which is just right. "
Gao Zhendong has been taking classes at Shuangstable for several days in a row. Basically, he can spend all his time in the conference room. Everyone is very tired, but they are also very passionate. Learning makes them happy. hapiness.
People from other subsystems also came to see Gao Zhendong. Seeing how busy they were, they didn’t want to bother them. They all knew that Vice President Gao came here this time mainly for the artillery crew. Fortunately, they There's nothing urgent.
However, Mr. Luo quit. With such continuous work, if there was any problem with his body, he would not be able to explain it to the National Defense Work Committee and the 12th Machinery Department, not to mention stopping work. It would be good to at least change the direction of work and relax your mind.
So, Mr. Guan, who had been waiting for a long time, received Mr. Luo’s instruction and ran over to announce to Vice President Gao that he should change his mind and take a rest. He took Gao Zhendong and ran away. Mr. He didn’t have any objections. , it is indeed not good for Gao Zhendong to focus on one thing continuously like this.
And they can use this time to digest the knowledge they have learned, and by the way, they can revise the preliminary plan for the bistable system preparation meeting.
Mr. Guan is responsible for protection, and the core of protection, the armor, has already met or even exceeded the expected needs of the next generation of tanks with the help of Gao Zhendong.
So now, he is very comfortable focusing on things like soft protection and after-effect protection instead of armor.
So he just took Gao Zhendong and looked around. It was obvious that he really wanted Gao Zhendong to rest.
However, Gao Zhendong couldn't sit still. Looking at these things, he suddenly asked: "Mr. Guan, do our tanks have smoke protection now?"
Aren't you engaged in soft protection? It's just right. I'll find something for you to do.
"Smoke protection? No, during the assault, we rely on artillery smoke bombs."
At this point, he suddenly reacted: "Mr. Gao, you mean the tank automatically With smoke bombs?”
Gao Zhendong really didn’t expect that the current tanks were not equipped with smoke protection. In fact, what he didn’t know was that until he sold both ends of the tank to Liangyi, our tanks Just installed these things.
He nodded after hearing this: "Well, yes, the support of artillery smoke bombs can only be coordinated in a planned manner. It is not easy to support during the battle."
Mr. Guan's eyes lit up: "Hey, this is an idea. In this way, the flexibility of use is much better."
Gao Zhendong shook his head: "Not only the flexibility of use, I estimate that in the future, individual anti-tank weapons will be greatly developed. On the battlefield, tanks need a means to conceal themselves and interfere with the enemy at any time, and weapons that use infrared sighting and guidance may appear on the battlefield in large numbers."
Mr. Guan thought about the infrared search and sight system that even we can make ourselves, and suddenly felt that this matter was really not Gao Zhendong’s whim, but a real threat that tanks will encounter on the future battlefield. .
I thought about it for a while, but I couldn’t figure it out for the time being. Since Vice President Gao has raised this issue, it must not be without purpose. He should have his own thoughts.
I called out to the comrades in my group and asked them to come over and listen. I thought a little guiltily that talking and chatting should not be considered too tiring for Vice President Gao. According to Mr. Luo’s explanation, I didn't violate it.
While everyone gathered around, Gao Zhendong also recalled some things from his previous life. Fortunately, this thing is just an idea and there is no technical difficulty.
