Chapter 315: It is not recommended to use it rashly, but it does not mean that it cannot be used

Judging from his record and performance on the battlefield, he has always been known for his fearlessness of death. Now it seems that even at the local level, this style remains the same.

After a moment of silence, the leader said, "Your report is too complicated and too professional. It's hard to digest it all at once. Tell me briefly what you think."

Once these words were spoken, it was like a relief.

Gao Zhendong quickly expressed his idea. When the leader heard that Gao Zhendong wanted to test many kinds of propellants, even completely different propellants, he immediately grasped the key to the matter: "One! Only one! One for your anti-tank missiles!"

The key to the matter is the key matter! When a leader is in charge, he must be first-rate in grasping the core of the problem.

Gao Zhendong wanted to struggle a bit more: "Leader, look, we've already done it, so it's okay to do something else while we're at it."

The leader said in a serious tone: "No, it's just this one. Do you think that no one else can do it except you? We still have so many comrades. We should trust our comrades. And I tell you, your kind must also be handed over to a professional factory like Changjian Factory to cooperate with you to do the specific work. You can only do the theory and design, and you can't do it yourself. Your Third Rolling Mill is not mature in this regard, so don't do it yourself."

The leader himself is a great man, and he understands the character of these great men too well.

When I see others are having trouble, I get anxious and immediately chase them away in a panic, saying, "Go away, I'll do it myself!"

Many people who are outstanding in their fields are like this.

Therefore, in order to prevent Gao Zhendong from acting rashly, he specifically reminded him of this matter.

Gao Zhendong believed in his comrades 100%, but he just wanted to have fun. After hearing what his leader said, he knew there was no room for maneuver, so he had to give up: "I believe it. Okay, leader, I'll listen to you."

The leader smiled and said, "That's right, hurry up and revise your crappy report. What the hell is this? Even nitroglycerin has been brought up."

Gao Zhendong was not happy with this: "No, boss, I need this. It's necessary and I need a lot of it. You have to keep it for me."

"Well, you have a lot of things to do. Just figure out the principles and designs and get busy with other work. Leave the specific tests and verifications to the comrades at the Changjian Factory. They're eager to learn more. Besides, you still owe me a book on grey system theory. Give me eight or ten chapters first."

In order to discourage Gao Zhendong from taking the initiative, the leader even half-jokingly started to ask for debt. Just this opening was almost like Sun Wukong asking Taishang Laojun for a thousand pills of Nine-Transformation Golden Elixir.

Gao Zhendong had no choice but to say, "It's almost done. I'm writing the first two chapters."

The tone was exactly the same as when some up masters in the previous life just created a new folder.

The leader then hung up the phone with satisfaction, while Gao Zhendong began to delete and modify the application for the research and development of the propellant with great difficulty. This was mainly because he was too ambitious and there were too many things used that even the Changjian Factory could not handle, so he had to submit a special report to the committee for this matter. Unexpectedly, after this report was submitted, only a small half of it remained after it went around the Defense Work Committee.

Then let's just stick to X-12. Use nitrocellulose, nitroglycerin, and vaseline to delete all the materials in the article and reduce them to less than ten types. What a pity, we can't set off fireworks.

In fact, to be honest, at this stage, HTPB is the best choice in terms of performance. It has many advantages and a wide range of adjustable burning speed.

To give a simple example, the MX intercontinental missile that was canceled by the Americans in the 90s was said to have used this thing. The reason for canceling it was not because of technology, but because of the Russians. Damn!

However, at that time, HTPB was unheard of in China. It would take time to make HTPB itself, not to mention the ratio of the fuel, oxidizer and other components. That would be even more time-consuming. So let's use the ready-made one from Citigroup to make an individual anti-tank bomb first.

Because HTPB is used as a binder in propellant, this is the beauty of technology, the binder can affect the performance of the propellant.

Not long after work started in the afternoon, the report was revised. Gao Zhendong asked the comrades in the confidential office to resubmit it to the Defense Work Committee. Fortunately, Gao Zhendong worked on a computer, otherwise it would have taken a lot of time to revise the report.

Just after I sent the report away, Su Weihua and his team arrived, which was a good opportunity to meet them. Fortunately, they were old acquaintances, otherwise it would be unknown whether I could meet them today.

Gao Zhendong was very happy to see Su Weihua. These days, it was rare for old classmates to see each other.

Su Weihua introduced the chief model designer and Engineer Qi to Gao Zhendong, and Gao Zhendong welcomed them with both hands.

"Hello, Mr. Qiu! Hello, Mr. Qi!"

Qi Gong shook hands and said with a smile, "Director Gao, Advisor Gao, I have long heard of your great name and have known you for a long time. I am glad to meet you in person."

The two talked on the phone when the No. 3 telemetry missile test was successful. Engineer Qi also said that he would come over to communicate with Gao Zhendong, and now it has finally happened.

Gao Zhendong also joked: "Yeah, I haven't thanked Mr. Qi for his blessing on my wedding yet."

When Gao Zhendong got married, Qi Gong specially asked Su Weihua to bring the gift money. He is also a real person. Several people chatted and laughed. Chief Model Designer Qiu looked at this man who was a little too young in front of him and couldn't help but secretly thought that there are talented people in every generation.

In fact, although Gao Zhendong has a delicate appearance, he does not have a baby face. Mr. Qiu feels that he is too young, but this is mostly relative to Gao Zhendong's known achievements.

Several people sat down and exchanged pleasantries. Qi Gong explained his purpose: "Director Gao, this time I came to ask for your advice, just as I said on the phone last time."

Gao Zhendong shook his head: "I don't deserve your advice, if there is anything we can discuss, let's talk about it."

Qi Gong was not polite and told Gao Zhendong about his ideas.

"Are you planning to reinforce the DJS-60D and install it into the imitation anti-ship missile system?"

Gao Zhendong was also happy to hear what Engineer Qi said. Isn't this the significance of developing single-board computers? They have a wide range of uses and can be used in all walks of life.

"Yes, but we are still considering how to use it. You are a researcher of DJS-60D and an automation major. You should be very familiar with computers and guidance. We would like to hear your opinion."

Gao Zhendong listened to Qi Gong's words and fell into deep thought.

While thinking, he asked some questions and Qi Gong answered them one by one.

After a long pause, Gao Zhendong said, "From the perspective of cost and the entire system, I do not recommend hastily putting the DJS-60D on the missile. The functions and performance of other subsystems on the missile cannot provide it with sufficient working conditions and resources. Simply put, it is a waste."

Although this sentence half-negated Engineer Qi's idea, General Manager Qiu and Engineer Qi gave Gao Zhendong a higher evaluation. From a practical point of view, he did not blindly promote it and ignore the reality just because he was a researcher of DJS-60D.

"At the same time, compared to anti-ship missiles, the maneuverability of their targets is extremely limited, and there are not too high requirements for the missile's control law, guidance algorithm, and flight control response speed. From the current situation you just described, the existing subsystems are sufficient. Under the premise that the overall combat technical indicators and subsystems do not change significantly, there is no need for improvement."

Gao Zhendong's words were very objective. General Manager Qiu said, "It seems that Advisor Gao's ideas are consistent with ours. The missile-borne computer is a bit ahead of its time."

Gao Zhendong nodded, then shook his head: "But if it is used, it is not useless. At least it is very beneficial in terms of reducing weight, reducing system complexity, and improving system maintainability."

These aspects immediately aroused the interest of the two CEOs. Although it seemed that there was no improvement in performance, it could actually increase combat effectiveness.

"Counselor Gao, please tell me in detail."

Gao Zhendong said: "Just now I heard that the inertial guidance of the missile uses an inertial platform, right?"

Gao Zhendong remembered seeing a photo in his previous life, in which the guidance system of the 544 missile was quite large.

Qi Gong nodded and said, "Yes, that's right. The platform is indeed rather bulky. Mr. Gao, do you want to replace the inertial platform with a computer?"

This seems unreliable. The computer itself does not have the ability to measure parameters such as angles and accelerations. The inertial platform is used to measure these.

Gao Zhendong smiled and said: "Computers do not replace inertial platforms, but replace inertial platforms with another inertial system. This inertial system is much easier to manufacture and maintain than the inertial platform in terms of size, weight, complexity, and difficulty. However, a real digital computer is necessary for this inertial system."

Qi Gong's interest was piqued immediately. The inertial platform of inertial navigation is a big deal. It is difficult to service, heavy, expensive, and difficult to process.

What Gao Zhendong was talking about is the new inertial navigation technology that began to develop in the 50s - strapdown inertial navigation.

Gao Zhendong introduced the principles and technical ideas of strapdown inertial navigation to the two.

He added: "I only think of these principles. I can't help you with the specific implementation."

Simply put, strapdown inertial navigation uses a set of accelerometers and gyroscopes directly mounted on the missile body to replace the original bulky, complex and expensive inertial platform.

The original function of the inertial platform is realized by a computer that solves the above sensor data in real time to form a virtual "digital inertial platform".

From the principle, we know that digital computers are necessary for strapdown inertial navigation platforms. Fake computers like analog computers cannot perform this function. This is also the reason why there were few ordinary missiles using strapdown inertial navigation before the 70s. They could not calculate.

Of course, strapdown inertial navigation is not without flaws, especially in the current technological environment, but it happens that anti-ship ballistics have terminal guidance, which largely offsets some of the flaws of strapdown inertial navigation.

Mr. Qiu and Engineer Qi are both very familiar with inertial navigation systems. After hearing Gao Zhendong's explanation, they thought about it for a while and became excited.

Really capable!
