Chapter 315 It is not recommended to use it rashly, but it is not impossible to use it
Looking at his resume and performance on the battlefield, he has always been known for not being afraid of death. Now it seems that even in the local area, this style is still the same.
After being stunned for a while, the leader said: "Your report is too complicated and too professional, and it is not easy to digest at the moment. Just tell me your specific thoughts."
As soon as he said this, he let go.
Gao Zhendong quickly expressed his thoughts. When he heard that Gao Zhendong wanted to test many kinds of propellants, even completely different propellants, the leader immediately grasped the matter. Key: "One type! Only one type! One type for your anti-tank missiles!"
The crux of the matter is the key thing! As a leader, your ability to get to the core of a problem is second to none.
Gao Zhendong still wanted to struggle: "Leader, look, we have done it all, it is okay to do other things on the way."
The leader said in a serious tone: "No, that's it. One, do you think that no one else can do it except you? We still have so many comrades, so you have to trust comrades. And let me tell you, your kind must be handled by professional factories like Changjian Factory. To do specific work, you can just do the theory and design, but you can’t do it yourself. The conditions in your third rolling mill are not mature, so don’t do it yourself.”
The leader himself is a good person, but he understands these good people very well. of virtue.
Seeing others making trouble, I feel panicked. In desperation, I immediately chase them away and say, "Go away, I'll do it myself!"
Many people who are outstanding in their fields are like this.
So in order to prevent Gao Zhendong from getting mad at him, he specially warned about this matter.
Gao Zhendong believed 100% in Comrade, but he just wanted to have fun. After hearing what the leader said, he knew that there was no room left, so he had to stop and say: "I believe it, OK, leader, I will listen to you." "
The leader smiled and said: "That's right, hurry up and change your bad report. What the hell do you want, even nitroglycerine."
Gao Zhendong doesn’t want to do this anymore: “No, boss, this is what I want to do. This thing is necessary and the amount is quite large. You have to keep it for me.”
"Okay then. You still have a lot to do on your own. After finishing the principles and design, you can quickly get busy with other work. Just leave the specific tests and verifications to the comrades at the Changjian Factory. I'm really looking forward to learning more skills. Besides, Now, you still owe me the book on gray system theory. Give me ten or eight chapters first.”
In order to dispel Gao Zhendong’s idea of going to school on his own, the leader even began to ask half-jokingly. The debt is coming, but this opening is just like Sun Dasheng asking Taishang Laojun to ask for a thousand pills and nine turns of golden elixir.
Gao Zhendong had no choice but to say: "Come on, come on, I'm writing the first two chapters."
The tone was exactly the same as when some up owners in the previous life just created a new folder. .
The leader then hung up the phone with satisfaction, while Gao Zhendong bitterly began to delete the application for research and development of propellants, mainly because he was too ambitious and used too many things, and even the Changjian Factory I couldn't figure it out, so I had to report this matter to the committee. I didn't expect that after this report, only half of it was left after going around the National Defense Working Committee.
Then let's just work on X-12. Nitrocellulose, nitroglycerine, and Vaseline have deleted all the materials in the article to less than ten types. It's a pity that there are no fireworks.
Actually, at this stage, HTPB is the best choice in terms of performance. It has many advantages and has a wide adjustable range of burning rate.
To give a simple example, the MX intercontinental missile that was axed by Citigroup in the 1990s is said to have used this thing. The reason for axing it was not because of technology, but because of the big hair, wow!
However, at this time, HTPB was unheard of in China. It would take time to make HTPB itself, not to mention the ratio of the combustion agent, oxidizer and other components inside, which would be even more difficult. It will take a long time. Let's use Citigroup's ready-made ones to get the individual anti-tank rounds first.
Because HTPB is used as a binder in the propellant, this is the beauty of the technology. The binder can affect the performance of the propellant.
Not long after going to work in the afternoon, the report was revised. Gao Zhendong asked the comrades in the confidential office to resubmit it to the National Defense Work Committee. Fortunately, Gao Zhendong worked with a computer, otherwise it would have taken a lot of time to revise the report.
As soon as the report was sent away, Su Weihua and the others arrived and picked them up just in time. Fortunately, they were old acquaintances, otherwise it was still unknown whether they would be able to see each other today.
Gao Zhendong was very happy to see Su Weihua. These days, it is rare for old classmates to meet him.
Su Weihua introduced the model chief engineer and Qi Gong to Gao Zhendong, and Gao Zhendong extended his hands to welcome them.
"Hello, Mr. Qiu! Hello, Mr. Qi!"
Qi Gong shook hands and said with a smile: "Director Gao, Consultant Gao, I have known you for a long time and have been friends for a long time. Now I can see you."
When the two of them successfully tested the No. 3 telemetry missile Through the phone call, Qi Gong also said that he would come over to communicate with Gao Zhendong, and now the trip has finally taken place.
Gao Zhendong also joked: "Yeah, I haven't thanked Mr. Qi for his blessing when I got married."
When Gao Zhendong got married, Qi Gong specially asked Su Weihua He came here with some money, and he is also a real person. A few people were chatting and laughing. Mr. Qiu, the chief model engineer, looked at the young man in front of him and couldn't help but secretly thought that he was truly the most talented person in his generation.
In fact, although Gao Zhendong looks pretty, he is not a baby face. Mr. Qiu felt that he was too young, more so compared to Gao Zhendong's known achievements.
A few people sat down and chatted for a while. Qi Gong explained the reason for his visit: "Director Gao, I am here to ask for your advice as I said on the last phone call."
< br>Gao Zhendong shook his head: "I don't dare to ask for advice. If there is anything we can exchange, let's talk."
Qi Gong was not polite and talked about his thoughts with Gao Zhendong.
“Are you going to reinforce the DJS-60D and install it into the imitation anti-ship missile system?”
Gao Zhendong was also happy after listening to Qi Gong's words. Isn't this the meaning of building a single-board computer? It has a wide range of uses and can be used in all walks of life.
“Yes, but we are still considering how to use it and how it can be used. You are the researcher of DJS-60D and major in automation. You should be very familiar with computers and guidance. , we want to hear your opinion.”
Gao Zhendong listened to Qi Gong’s words and fell into thinking.
While thinking, he asked some questions, and Qi Gong also answered them one by one.
For a long time, Gao Zhendong said: "From a cost and system-wide perspective, I don't recommend putting the DJS-60D on the missile rashly. The functions and performance of other subsystems on the missile cannot provide enough for it. Working conditions and resources are, simply put, wasted.”
Although this sentence semi-denies Qi Gong's idea, Mr. Qiu and Qi Gong have a higher evaluation of Gao Zhendong. From a practical point of view, they should not blindly promote DJS-60D because they are researchers of DJS-60D. Reality.
"At the same time, compared with anti-ship missiles, the target's maneuverability is extremely limited. The missile's control law, guidance algorithm, and flight control response speed are not in high demand. From what you just introduced Judging from the current situation, the existing subsystems are sufficient. As long as there are no major changes in the overall combat technical indicators and each subsystem, there is no need for improvement. "
Gao Zhendong's words are very objective, Qiu said. The general said: "It seems that Advisor Gao has the same idea as ours. The missile-borne computer is a bit ahead of its time."
Gao Zhendong nodded, then shook his head: "But if you want to use it, it's not impossible. It’s useful, at least in terms of weight reduction, system complexity, and system maintainability.”
These aspects immediately piqued the interest of the two bosses. It seems that there is no improvement in performance, but it can actually increase combat effectiveness.
"Advisor Gao, please explain in detail."
Gao Zhendong said: "I heard just now that the missile's inertial guidance uses an inertial platform, right?"
Gao Zhendong remembers his previous life I have seen a photo. The guidance system of the 544 missile is quite large.
Qi Gong nodded: "Yes, that's right. The platform is indeed cumbersome. Consultant Gao, do you want to use a computer to replace the inertial platform?"
Why don't you feel uncomfortable thinking about this? Damn it, the computer itself does not have the ability to measure parameters such as angle, acceleration, etc. This inertial platform was originally used to measure these.
Gao Zhendong smiled and said: "The computer does not replace the inertial platform, but replaces the inertial platform with another inertial system. This inertial system is much lower in volume, weight, complexity, manufacturing and maintenance difficulty than the inertial platform, but it is really A digital computer is necessary for this kind of inertial system.”
Qi Gong’s interest immediately arose. The inertial navigation platform is a big deal, difficult to maintain, and heavy. Expensive and difficult to process.
What Gao Zhendong is talking about is the new inertial navigation technology that began to develop in the 1950s - strapdown inertial navigation.
Gao Zhendong introduced the principles and technical ideas of strapdown inertial navigation to the two.
After finishing speaking, he added: "I only think of these principles and the specific implementation, and I can't help."
Simply put, strapdown inertial navigation uses a set of acceleration and gyroscopes directly installed on the missile body to replace the original heavy, complex and expensive inertial platform.
The original function of the inertial platform is realized by a set of virtual "digital inertial platforms" formed by computers that calculate the above-mentioned sensor data in real time.
From the principle, we know that digital computers are necessary for strapdown inertial navigation platforms. Fake computers like analog computers cannot complete this function. This is also the case before the 1970s, when it was rarely used. The reason is that ordinary missiles with inertial guidance cannot be calculated.
Of course, strapdown inertial navigation is not without its flaws, especially in the current technical environment. However, anti-ship ballistics happen to be terminally guided, which offsets strapdown to a large extent. Some shortcomings of inertial navigation.
Boss Mr. Qiu and Qi Gong are very familiar with the inertial navigation system. After hearing Gao Zhendong’s explanation, he thought about it for a while and became excited.
It's really possible!
