Chapter 399 Professor Luo's Confusion (only 4k today)

Seeing that Gao Zhendong knew what was going on, Lou's father stopped talking about it and started talking about Lou Shouxing's whereabouts.

"Your eldest brother contacted our family not long ago. The Bailing Electronics Exhibition you mentioned will open on September 9nd. He has already led a team there. After attending the exhibition, he will come back. Didn't you ask him to come back last time?"

Gao Zhendong nodded: "Well, that's fine. This exhibition is quite effective for the revitalization of electric production."

The publicity effect of large-scale international exhibitions at this time was much stronger than in the future. Unlike Gao Zhendong's previous life, some large-scale electronic game exhibitions that were once in their heyday had reached the point where there was no successor and had to be discontinued.

On Monday, when Gao Zhendong got to work, the first thing he did was to receive the personnel. There were two batches of personnel.

A group of people came from his alma mater, Wudaokou College, a total of three people, two men and one woman, all of whom were his juniors. They were related to the third branch of the third rolling mill.

The other group was sent by the Defense Work Committee. There were also three people, all men. They graduated from different universities and their personnel relationships were also with the Defense Work Committee. Gao Zhendong was only responsible for their use.

The students’ majors are also very interesting. All of them graduated from the Automation major at Wudaokou. After all, Gao Zhendong majored in Automation, and his teacher also majored in this field.

But it's different for those from the Defense Working Committee. None of the three people graduated from the automation major. It seems that the Defense Working Committee is quite familiar with Gao Zhendong's recruitment situation. From a professional perspective, there is no crowding, but the focus is on differentiation.

Nowadays, once children go to work in other places, it is difficult for them to return home in a short period of time. Therefore, this time when they graduate, they are basically given enough time to report back so that they can go back and spend time with their families.

See you next time. If you are lucky, it will be half a year or a year. If you are far away, it will be difficult to see each other again in a short period of time except for getting married and having children.

Spring Festival travel? How can we afford this these days? Not to mention the future transportation volume of transporting hundreds of millions of people back and forth within ten days. Even if there are not so many people at this time, and we give a 10% discount, it is still impossible to transport tens of millions of people.

This scale of concentrated migration, even if it happened in Gao Zhendong's previous life, would have resulted in immediate traffic paralysis in any other country except ours. There is no other possibility.

Therefore, Gao Zhendong gave a unified time for students to report when they graduated, August 8th. Gao Zhendong was lazy and he finished everything in one day.

As the chief engineer of the third factory, he had to meet these talented young people in person first. Apart from the usual welcome and encouragement, Gao Zhendong only arranged one thing for them.

——First, Liang Faming will take them to visit the technical department to familiarize themselves with the situation, and then they will all go to various workshops to take turns and stay for a month.

Although what they will do in the future may not necessarily be closely related to a specific workshop in the Third Branch Factory, the necessary front-line experience will be beneficial to them.

It is not necessary for them to learn the labor production skills of these workshops. After all, what they do in the future will probably not have much to do with these workshops. However, it is still necessary for them to go to the front line first, feel the atmosphere, and get close to the masses.

For those who engage in applied research, the word "down-to-earth" is very necessary. It is not uncommon for comrades who have just started working to think about theory without considering the reality and make jokes.

If you start out in a high and mighty manner, it will be difficult mentally to humble yourself later. If you don't lay a solid foundation, it will be costly to correct it later.

The students had no objections and accepted the arrangement with high morale.

These days, you can't go anywhere to work without working. Many factories and mines are still in their start-up stages. It's common for people to put their professional skills aside, live in tents, and build the factory brick by brick.

Coming to the Third Factory, where conditions are complete, with dormitories to live in, a canteen to eat in, all production factors complete, and the ability to directly participate in actual production work, is already very good working condition.

As for the fact that they cannot participate in specific work for this month, Gao Zhendong can still wait. They have military training in the first two weeks of high school and the first month of college. It doesn't necessarily affect their studies. After all, sharpening the knife does not delay the chopping of wood.

This was the only big thing that happened this morning. This time, Gao Zhendong's technical force became even stronger. After all, the people in the original third factory had relatively narrow professional directions.

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 classes. September is approaching and school is about to start. Accepting graduates also means that school has started and new students will enroll.

However, the classes taught by Gao Zhendong are obviously not something that freshmen can learn. He has not even learned advanced mathematics, so how can he learn the principles of automatic control? Have you ever heard of the "Book of Heaven"?
Similarly, the same goes for data structures. If you have not learned C language, theoretically it will not hinder your learning of data structures, but it will be more troublesome for the practice of data structures.

"Mr. Gao, let's finalize the course schedule. If you have work that prevents you from attending class, don't worry. Just let us know and we'll make the corresponding adjustments. We already have plans and arrangements for this."

Dean Dai knew that given Gao Zhendong's situation, it was very likely that he would suddenly have important work that would affect his courses. In order not to delay students' studies and at the same time reduce Gao Zhendong's pressure, he made corresponding arrangements in advance.

Gao Zhendong smiled and said, "I will try not to affect you. If there is no other way, I will notify you in time."

Dean Dai took out another paper shell and said, "Chief Engineer Gao, this is your work permit at our school. First, it will make it easier for you to work and enter and leave the school. Second, you want to freely read our library. This will be enough for you."

Gao Zhendong had a lot of similar things, but this one was a little different. He happily took it.

As for professions such as teachers and doctors, even though there were many controversies for some reasons in Gao Zhendong's previous life, deep down, Chinese people still generally have a good impression and high evaluation of these professions.

A teacher is one who teaches and imparts knowledge.

A doctor cures illnesses and saves lives.

These are all wonderful jobs, and the reason why they are sometimes criticized so harshly is probably because of the most sincere expectations.

Therefore, he was quite proud of being able to become a teacher at a school like Beijing University of Technology, even if he was only a specially hired one.

After Dean Dai finished his own business, he said goodbye to Gao Zhendong.

He and Professor Luo actually didn't know that the other party was going to look for Gao Zhendong today, and they met at the Third Branch Factory. He also knew that it was probably inconvenient for him to hear what Professor Luo wanted to say to Gao Zhendong.

Their school is special. Even if a graduate is working on his graduation project, the principal may not listen to his specific work, so he will just leave after finishing his work.

Professor Luo watched the conversation between Dean Dai and Gao Zhendong and learned that Gao Zhendong was going to teach at their school. He was very happy.

If we can bring this person into the school, it will be much more convenient to handle any issues in the future. The school leaders have some ideas.

Killing two birds with one stone, not only did he get the golden eggs, but he also brought back the hen that laid the golden eggs.

He also inquired with great interest about the specific courses Gao Zhendong was going to take, and said frankly that if he had time, he would definitely bring his students to listen to Gao Zhendong's class.

Professor Luo knew that, apart from practical aspects, Gao Zhendong's theoretical knowledge was definitely better than his own, and it would be beneficial for him to listen to his lectures.

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 visit this time.

"Boss Gao, this is the situation. We have designed a high-low pressure grenade launcher based on your instructions, and it has now reached the stage of live ammunition testing."

Gao Zhendong was still very surprised when he heard this. It had not been too long since Professor Luo last communicated with him, and they had already started the live-fire test.

Among them, the simple principle of high and low voltage and Gao Zhendong's thorough explanation are certainly the reasons, but the unremitting efforts of Professor Luo and his students are also a very important part.

Since they have entered the live-fire test and have come to me, there must be some problem that they cannot solve.

"So fast? Professor Luo's work progress is encouraging." Gao Zhendong complimented him first. Besides, the other party's progress was indeed worthy of the praise.

Professor Luo shook his head and said, "I don't deserve Mr. Gao's praise. I have done well in the areas you have pointed out, but I am ashamed of the other areas. There are still some problems."

To put it bluntly, only those who have been taught by Gao Zhendong can understand, but those who have not been taught are at a loss, which makes Professor Luo a little embarrassed.

Gao Zhendong smiled and said, "Tell me the details of the situation."

"We have completed the design of the launcher and the high- and low-pressure grenades, and have also conducted live-fire tests. The results are pretty good. The weight, structure, range, and accuracy are all within the range approved by the military. Even the indirect fire function they specifically requested is no problem."

Talking about these aspects, Professor Luo is still very proud. After the sample of the rifle-mounted grenade launcher was test-fired, the representatives from the army praised it highly, saying that it met their needs very well and filled the gap in firepower.

Thanks to Gao Zhendong's detailed guidance, these aspects were done well. After all, Gao Zhendong only needed to mark the dimensions on the design drawing. Professor Luo's team was not stupid either, and they did a good job with these materials.

"That's great. The main advantages and requirements of rifle-mounted grenades are in these areas. It would be great if they can fill the gap in firepower between squad firearms and assault firepower. As for the grenade itself, it's actually relatively simple."

As for a grenade, as long as it can explode, it's fine.

What Gao Zhendong didn't expect was that after he said this, Professor Luo became even more embarrassed.

"Mr. Gao, you may think that grenades are simple, but maybe our level is limited, the problem lies with the grenades." Professor Luo blushed a little.

Gao Zhendong was a little surprised. Could it be that he couldn't even throw a grenade?

However, he remembered the mistake he made last time when he introduced the principles of high and low pressure transmission to Professor Luo, so he didn't say much, but waited for Professor Luo to speak himself.

After all, the situation last time where “I thought you understood, but it turns out you didn’t” was really hurtful.

Professor Luo did not hide anything and directly stated the problem: "According to your idea at the time, you wanted to develop a multifunctional grenade that could both attack light armor and deal enough damage to enemy infantry. We tried to design one, but the results of live-fire shooting were not ideal."

"So after your test, where is the problem?"

"It's fine for hitting people. The effective killing range of the fragments is up to ten meters. But hitting armor is like tickling. The penetration depth is less than twenty millimeters."

In those days, there was no concept of "gua sha".

Gao Zhendong frowned. That’s not necessary. Grenades are very simple and are also Professor Luo’s and their expertise.

So I didn't show off last time and didn't take the initiative to draw the grenade warhead, mainly because I was afraid of making a fool of myself.

"Professor Luo, can you show me your warhead design?"

Professor Luo nodded, took out a drawing and handed it to Gao Zhendong.

Gao Zhendong understood the root of the problem at a glance. It was the same as when he designed the disposable rocket launcher to take anti-infantry into consideration, which caused the penetration to drop from over 600 to 550.

But he really didn't think about this, and Professor Luo and his team had no relevant research.

Once the problem is found, things will be easier to solve.

"Professor Luo, your design is to use shaped-energy armor-piercing to complete the task of anti-light armor, while the prefabricated fragments or steel balls around the projectile body can also take into account the killing of personnel, right?"

"Yes, we thought that the armor-piercing technique requires inward compression, and the outward shock wave would just push the prefabricated fragments to kill the personnel, so we can take care of both sides."

Gao Zhendong smiled: "This idea is correct, but there is actually a problem here. Prefabricated fragments will have a great impact on the armor penetration depth."

Professor Luo was confused: "One is inward-looking, the other is outward-looking, and they don't interfere with each other. How can this have an impact?"

This is where the energy-piercing armor-piercing technique goes against common sense. These two shock waves heading in completely different directions can actually affect each other.

"Professor Luo, the acoustic impedance of metal fragments is higher than that of explosives, so the shock wave of the explosion will be reflected at the fragments, affecting the collapse and closure of the liner. This will overlap and affect the original shock wave, increasing the collapse speed of the liner and thus the jet speed. At the same time, the fragments will increase the boundary constraints of the charge and the charge filling ratio, further increasing the jet speed."

This time, Professor Luo and his team are at a loss.

"Boss Gao, isn't it good to increase the jet speed? The higher the jet speed, the stronger the armor-piercing ability, right?"

Although I didn't know that fragments would increase the jet speed, now that I know it, I think it's a good thing.

But since Mr. Gao has raised this issue, it may not be that simple. One of Professor Luo’s students “acted stupid” in time to avoid embarrassment for Professor Luo.

　Well, I encountered the situation I mentioned at the beginning, "maybe 4K occasionally", the traffic jam was too serious.

　　Can you believe that it took more than 2 hours to walk 2 kilometers into the scenic area? And it wasn't blocked, it was always moving slowly, and I couldn't do anything else.

　　After going uphill for a long time with half clutch, the clutch plate started to smell.

　　I will resume writing two chapters of 6k tomorrow.
