Chapter 399 Professor Luo’s confusion (only 4k today)
Seeing that Gao Zhendong knew what was going on, Lou’s father stopped mentioning the matter and instead talked about Lou Shouxing’s whereabouts.
"Your eldest brother contacted your family not long ago. The Bailing Electronics Exhibition you mentioned opens on September 2nd. He has already led the team there. After participating in this exhibition, he will come back. You go up Didn’t I say that I wanted him to come back once?”
Gao Zhendong nodded: “Well, that’s fine. This exhibition is quite effective for revitalizing the electronic industry.”
This. The publicity effect of large-scale international exhibitions at that time was much stronger than that of the future. Unlike Gao Zhendong's previous life, some large-scale video game exhibitions that were once popular had reached the point where they had no successors and had to be discontinued.
——
On Monday, when Gao Zhendong went to work, the first thing he did was to receive people. There were two batches of people.
A group of three people came from his alma mater, Wudaokou College, two boys and one girl. They were all his junior brothers and sisters. Their relationship was in the third mill of the third rolling mill.
The other group was sent over by the National Defense Working Committee. There were also three people, all of whom were male. They graduated from different schools, and the personnel relationship was also with the National Defense Working Committee. Gao Zhendong Responsible for use only.
The majors of the students are also very interesting. Those from Wudaokou all graduated with automation majors. After all, Gao Zhendong was born in automation, and his teacher also chose this major.
It's different for those from the National Defense Work Committee. None of the three people graduated from the automation major. It seems that the National Defense Work Committee is relatively familiar with Gao Zhendong's recruitment situation. From a professional point of view, there is no group. On the other hand, it focuses on differentiation.
In this year, once a child goes to work in other places, it is difficult to go home in a short time. Therefore, this time after graduation, basically the time for registration is relatively sufficient, so that you can spend time with them when you go back. Spend time with your family.
See you next time. If you are lucky, it will take half a year or a year. If you are far away, I am afraid that apart from getting married and having children, it will be difficult to see each other again in a short time.
Spring Festival travel rush? How can we afford this these days, let alone the kind of transportation capacity that will transport hundreds of millions of people back and forth within ten days in the future? Even if there are not so many people at this time, even if we give a discount, tens of millions of people are still unthinkable. Don't think about it.
A centralized migration of this magnitude, even if it were placed in Gao Zhendong’s previous life, in any country other than us, the result would be immediate traffic paralysis, and there is no second possibility.
Therefore, when Gao Zhendong graduates, the time given to him is the same. Registration is on August 15th, and it is concentrated on this day. Gao Zhendong is so lazy that he can eat a spoonful of it in one day.
As the chief engineer of the third factory, he still had to meet these talented people in person. In addition to the usual welcome and encouragement, Gao Zhendong only arranged one thing.
——First, Liang Fafa took them around the technical department to get familiar with the situation, and then they all went to various workshops for rotation and stayed for a month.
Although what they will do in the future may not necessarily have much to do with a specific workshop of the No. 3 Factory, the necessary front-line experience will be good for them.
They are not necessarily required to learn the labor and production skills of these workshops. After all, the things they will do in the future will probably not have much to do with these workshops, but it is still very important to go to the front line first, feel the atmosphere, and get to know the masses. It is necessary.
For those engaged in applied research, the word "down-to-earth" is very necessary. It is not uncommon for comrades who have just joined the work to only think about theory without considering reality, and make jokes.
It will be difficult to think about it from an ideological point of view if you are high-minded as soon as you start. If you want to sink down in the future, it will be more expensive to correct it later if the foundation is not laid well.
The students had no objections and accepted the arrangement with high spirits.
These days, you are not allowed to work anywhere you go to work. Many factories and mines are in the start-up stage. It is common for you to put your major aside and live in a tent to build the factory brick by brick.
The conditions when they came to the No. 3 Factory were complete. They had dormitories to live in, a canteen to eat, and complete production factors. They could directly participate in actual production work. This was already a very good working condition.
As for them not being able to participate in specific work this month, Gao Zhendong can still afford to wait. He is still in military training for the first two weeks of high school and the first month or so of college. It is not necessary to delay his studies. Sharpening the knife will not delay the woodchopping. .
The big event in the morning was this one. This time, Gao Zhendong’s technical strength became more and more powerful. After all, the people in the third factory originally had a narrow professional field.
In the afternoon, Gao Zhendong received a group of people from Beijing University of Technology.
There are mainly two people, one is Dean Dai and the other is Professor Luo.
The former came to communicate with Gao Zhendong about class matters. It was almost September and the school was about to start. Being able to accept graduates also meant that school had started and new students were about to enroll.
However, the class Gao Zhendong took was obviously not something that freshmen could learn. He had never studied advanced mathematics before. He was just learning Mao’s automatic control principles. Have you heard of the Book of Heaven?
Similarly, the same applies to data structures. If you have never learned C language, theoretically it will not delay the learning of data structures, but the practice of data structures is more troublesome.
"Mr. Gao, this is how we have decided on this course schedule. If you have any temporary work that prevents you from attending class, don't worry. Just give us a notification and we will make corresponding adjustments. We are very concerned about this. Plans and arrangements have been made.”
Dean Dai knows that in Gao Zhendong’s case, it is very likely that important work will suddenly have an impact on the curriculum. In order not to delay students’ learning, but also reduce the number of students. Xiao Gao Zhendong's pressure made corresponding arrangements in advance.
Gao Zhendong smiled and said: "I will try not to affect it. If there is nothing I can do, I will notify you in time."
Dean Dai took out another paper book: "General Engineer Gao, this is your work permit in our school. Firstly, it is convenient for you to work and enter and leave the school. Secondly, don't you want to browse our library freely? With this That’s it.”
Gao Zhendong had a bunch of similar things, but this one was different, so he took it happily.
For professions such as teachers and doctors, even though there was a lot of controversy in Gao Zhendong's previous life due to some reasons, fundamentally speaking, Chinese people still generally have a good impression and high evaluation of these professions.
Teachers preach and teach.
Doctors treat illnesses and save lives.
They are all very beautiful jobs. The reason why I sometimes scold them fiercely is probably because of the most simple expectations.
So he is quite proud to be a teacher at a school like Beijing University of Technology, even if he is only a specially appointed one.
Dean Dai finished his own affairs and said goodbye to Gao Zhendong.
He and Professor Luo actually didn’t know that the other party was looking for Gao Zhendong today, and they met at the No. 3 Factory. He also knew that it was probably inconvenient for him to listen to what Professor Luo was going to say to Gao Zhendong. .
Their school is special. Even if one of the following graduates is doing graduation project, the principal may not be able to listen to the specific work he is doing, so he will run away after finishing his own work.
After watching the exchange between Dean Dai and Gao Zhendong, Professor Luo was very happy to know that Gao Zhendong was going to their school.
If we can introduce this person to the school, it will be more convenient for anything in the future. The school leaders have ideas.
Kill two birds with one stone. Not only did he get the golden egg, but he also got back the hen that laid the golden egg.
He also enthusiastically inquired about the specific courses that Gao Zhendong would take, and said that if he had time, he would definitely take his students to Gao Zhendong's classes. Professor Luo knew clearly that aside from practical matters, Gao Zhendong's theoretical knowledge must be better than his own, and it would be good for him to listen to his class.
This is not because he has no ability, but because of the limitations of the times.
After saying this, Professor Luo talked about the main purpose of his coming here this time.
"Mr. Gao, this is the situation. According to your instructions, we designed a gun-mounted grenade launcher based on the high and low voltage principle. Now it has reached the stage of live ammunition testing."
Gao Zhendong was very surprised when he heard this. The last time Professor Luo communicated with him, not too long ago, they had already entered the live ammunition test.
Among them, the simple principle of high and low voltage and Gao Zhendong’s thorough explanation are certainly indispensable, but the unremitting efforts of Professor Luo and his students are also a very important part.
Since they entered the live-fire test and came to find themselves, there must be some problem that they cannot solve.
"So fast? The progress of Professor Luo's work is gratifying." Gao Zhendong gave him a hat first, and besides, the other party's progress really deserves this praise.
Professor Luo shook his head: "I don't deserve the praise from Mr. Gao. I have done pretty well in the aspects you have pointed out, but I am ashamed of myself in other aspects. There are still some problems."
To put it bluntly, those who have not been taught by Gao Zhendong are blind, which makes Professor Luo a little embarrassed.
Gao Zhendong smiled and said: “Let’s talk about the specific situation.”
"We have completed the formal design of the launcher and high- and low-pressure grenades, and have also conducted live-fire tests. The situation is okay. The weight, structure, range, and accuracy are all within the range approved by the army. Even they deliberately There is no problem with the deflection function. "
Speaking of these aspects, Professor Luo is still very proud. After the sample of the grenade launcher was tested, the representatives from the army were full of praise. It fits their needs very well and fills the gap in firepower perfectly.
Thanks to Gao Zhendong’s detailed guidance, these aspects have been done well. After all, Gao Zhendong only had to mark the dimensions on the design drawing. Professor Luo’s team is not a fool. They took these materials Well done too.
"That's good. The main advantages and requirements of gun-mounted grenades are in these places. It would be great if they can fill the firepower gap between squad firearms and attack firepower. As for the grenade itself, it is It's relatively simple. "
Grenade, it can explode.
What Gao Zhendong didn't expect was that Professor Luo would be even more embarrassed when he said this.
"Mr. Gao, you may think grenades are very simple, but maybe our level is limited and the problem lies in grenades." Professor Luo's face turned a little red.
Gao Zhendong is a little surprised. He can't even handle a grenade, right?
However, he remembered the mistake he made when he introduced the principles of high and low voltage launch to Professor Luo last time. He didn't say more, but waited for Professor Luo to say it himself.
After all, the "I thought you understood, but you didn't understand" situation last time was a bit hurtful to say.
Professor Luo did not hide anything and directly stated the problem: "According to your idea at the time, it was to develop a multi-functional grenade that could not only resist light armor but also deal a sufficient blow to enemy infantry. We tried to design a type. The results of the live ammunition shooting are not very satisfactory.”
“Then what’s the problem after you tested it?”
“It’s no problem to hit people. The effective damage range of the fragments is ten meters, but it can’t hit armor. Just like scratching, the depth of the nail penetration is less than 20 millimeters. "
In these days, there is no such thing as "gua sha".
Gao Zhendong frowned, no, grenades are very simple, and this is Professor Luo's specialty.
So I didn't show off last time, and I didn't go overboard and draw the grenade warhead, mainly because I was afraid of making myself laugh.
"Professor Luo, can you show me your warhead design drawing?"
Professor Luo nodded, took out a drawing and handed it to Gao Zhendong.
Gao Zhendong understood at a glance that the root of this problem was the same as when he designed a disposable rocket launcher for anti-infantry purposes, which would cause the penetration to drop from more than 600 to 550.
But he really didn’t think of this. Professor Luo and the others had no relevant research.
Once the problem is found, things will be easier to solve.
"Professor Luo, in your design, you want to use concentrated energy armor-breaking to complete the anti-light armor mission, and at the same time, the prefabricated fragments or steel balls around the projectile can also kill and injure personnel, right?"
"Yes, we think that the requirement for concentrated energy armor breaking is to squeeze inward. The outward shock wave will just push the prefabricated fragments to cause damage to personnel. We can take care of both sides."
Gao Zhendong smiled: " This idea is correct, but there is actually a problem here. The prefabricated fragments will have a great impact on the depth of armor penetration."
Professor Luo was confused: "One is inward and the other is outward. Can this have an impact without interfering with each other? ”
This is where Focused Armor Breaking is a bit counterintuitive. These two shock waves going in completely different directions can really affect each other.
"Professor Luo, the acoustic impedance of metal fragments is higher than the acoustic impedance of explosives, so the shock wave of the explosion will be reflected at the fragments, acting on the crushing and closing of the explosive cover. This will The fragments superimpose and influence each other with the original shock wave to increase the crushing speed of the charge cover, thereby increasing the jet velocity. At the same time, the fragments will increase the charge boundary constraints and charge filling ratio, further increasing the jet velocity. ”
This. Suddenly, Professor Luo and the others could not be punished.
"Mr. Gao, isn't it good that the jet speed has increased? The higher the jet speed, the stronger the armor-breaking ability?"
Although I don't know that fragmentation will cause the jet speed to increase, but Now that I know it, I think it’s a good thing.
But since Mr. Gao mentioned this issue, it might not be that simple. One of Professor Luo's students "acted stupid" in time to avoid Professor Luo's embarrassment.
