Chapter 468 Give them a graduation project
On December 12th, Tuesday, after finishing his class, Gao Zhendong turned around and went to find Dean Dai.

"Chief Engineer Gao, please take a seat. Every time you come to class, apart from your work with Professor Luo and others, you are basically in a hurry. It's difficult to see you even if I want to chat with you." Dean Dai said with a smile.

"Not only Professor Luo, I also go to Professor Liu's place occasionally, haha." Professor Liu's prototype gun was almost finished when Gao Zhendong came to teach on his first day in mid-September. In the meantime, Gao Zhendong would go there occasionally to offer some minor suggestions for improvement.

The most important thing is that Gao Zhendong recommended General Xiang to Professor Liu. Don’t forget that the ABS shell and optical plastic of the disposable rocket launcher were all made by General Xiang, and introducing him to Professor Liu was mainly to solve a "simple" problem: the handguard and buttstock of the new gun.

Those who know the business know that wooden stocks and handguards cost much more than plastic ones.

What’s different this time is that Gao Zhendong’s suggestion to Professor Liu and others is to replace the steel folding support with an adjustable folding support. The steel support is too torturous in winter, and the handguard part also has a herringbone guide.

It is definitely impossible to make a herringbone guide rail with wood. Let’s not talk about whether it can be made. Even if it can be made, the price will be sky-high.

As for the adjustable folding rest, although Gao Zhendong did not suggest an adjustable cheek rest, he still proposed adjustable length. Gao Zhendong's suggestion is an adjustable steel tube frame + plastic outer covering.

This requires suitable plastics. Mr. Xiang has experience in disposable bobbin ABS and a twin-screw extruder. Whether it is the material itself or the processing technology, it is the most trustworthy.

As a result, the test time of the prototype gun was pushed back a bit, and it was estimated that it would not be ready until early 61. Fortunately, even so, there was still plenty of time and it could be completed earlier than originally planned.

Dean Dai also knew that Gao Zhendong was very busy over there, so he smiled and said, "Then I have to thank you for your support to them first, haha. You came all the way to see me today, is there something good you want to take care of for me?"

Gao Zhendong sat down and took things out of his bag.

"I don't dare to take care of you, but I do have something I want to discuss with Dean Dai to see if it can be moved forward. If not, I will look for someone else."

He had a reason to look for Dean Dai. The job of integrated circuit design was most closely related to the various departments and majors in Dean Dai's college, and he was born to be here.

Seeing that Gao Zhendong really had something good, Dean Dai immediately became interested. He also brought information, and it was such a thick stack, it must be good stuff!

"Wow, there's quite a lot of content. I guess I'll have to eat my fill today." Dean Dai joked.

Gao Zhendong took out the materials but did not hand them over. He asked for their intentions first. If there were no intentions, he would put them back.

"Dean Dai, you should know about integrated circuits, right?"

Dean Dai's eyes sparkled: "I know a little bit, but I don't know the details. How come this is related to integrated circuits?"

Integrated circuits were just born at that time, so it was normal that most people in China did not understand them, but they had heard of them. China was not completely isolated and was still trying to get knowledge from outside, but it was just relatively difficult.

Dean Dai knew that this was the latest technology, which played a very important role in electronics, automatic control, and electromechanical engineering, and had a very broad prospect.

I originally wanted to offer some courses in this area, but there is no source of knowledge. No one understands and is still groping in the dark.

When he heard that what Gao Zhendong had in his hand was related to integrated circuits, he became very excited, what a great fortune, what a great fortune!
Gao Zhendong nodded: "Yes, the core of integrated circuits is divided into two parts, one is design, and the other is manufacturing. On the manufacturing side, there are related projects to promote it, and the other problem now is the design problem."

Dean Dai had no idea that there was such a thing. Manufacturing was being promoted, and the design was a problem. Doesn't that mean that manufacturing was on the way? And this matter was definitely related to the young man in front of him.

Gao Zhendong didn't tell him the specific details, so he couldn't ask, but that didn't prevent him from making his own judgment in his head.

"Then what you have in your hand, Chief Engineer Gao, is something related to integrated circuit design?" Dean Dai asked, resisting the urge to grab it.

Gao Zhendong nodded: "Yes. I spent a lot of time exploring it, and I have some design ideas and experience for the current integrated circuit technology. And now I have a lot of integrated circuits that need to be designed in my plan, but I am short of manpower."

Dean Dai no longer knew how far this young man had progressed in various fields. Anyway, when he talked about this emerging technology that was still a blank in the country, his tone was as simple as drinking a sip of water.

"Chief Engineer Gao, you want to bring out a group of integrated circuit design talents, right? That's no problem. We have many suitable majors in our school, and there are probably many students who are interested. You can choose any one you want. We will definitely support and cooperate with you."

Dean Dai jumped in without waiting for Gao Zhendong to make a request. What a great opportunity! This person's alma mater is not simple either. If he hadn't had the affection for the classes he took here, he would have gone back to his alma mater to call people.

Wow, Dean Dai can answer the questions quickly.

This blocked many of Gao Zhendong's arguments and disrupted his train of thought.

"Oh, right. Originally, I was going to wait until I finished Data Structures this semester and had a batch of seeds in school, then switch to this course. But I didn't expect that plans are not as good as changes, and the situation develops faster, haha."

Gao Zhendong was definitely not going to teach the same course twice, including "Principles of Automatic Control", not to mention "Data Structure", which was a course that could be completed in one semester. Many young teachers from Beijing University of Technology came to listen to his class. These were the seeds planted by Gao Zhendong. He planned to teach a course only once, and leave the rest to these people.

He is short on time and has a lot of useful information, so instead of repeating himself, he might as well turn to new courses and continue to cultivate seeds.

Later, a widely circulated internal proverb at Beijing University of Technology was "Professor Gao teaches - just once". This is how it came about. It became a secret code for people from Beijing University of Technology to contact each other after graduation.

Dean Dai was delighted when he heard this.

The first piece of joy is that the progress of integrated circuits is encouraging. Although Gao Zhendong did not explicitly state the specific situation of the "development of the situation", we can tell from his words that the integrated circuit manufacturing project is progressing at an absolutely rapid pace, so much so that Gao Zhendong could not keep up with the design course that he had originally planned to start in the next semester.

Second, judging from Gao Zhendong's arrangement of changing courses after each one, he definitely has a lot of new things, and he can probably teach new things every semester.

The third joy is that it seems that Chief Engineer Gao is planning to teach at Beijing University of Technology for a long time. This will bring so many new things to Beijing University of Technology and cultivate a lot of teaching talents. Moreover, they are all unique skills. It will be a huge profit.

"Okay, Mr. Gao, just tell me what you need. I will fully support you. If I can't support you here, I will ask the school for support. No matter what, I will arrange your affairs." Dean Dai patted his chest.

While handing over the integrated circuit design information, Gao Zhendong introduced his ideas.

Dean Dai listened and read, nodded repeatedly, and was very happy. Just this book of materials, plus Gao Zhendong's class, basically established the leading position of Beijing University of Technology in this direction for some time to come.

"Chief Engineer Gao, I have a preliminary idea. Do you think it will work? We will teach this course to senior students in the Department of Electrical Engineering. They have the most comprehensive knowledge structure and the strongest learning ability. When they have learned enough, if they are willing, we will arrange this as their graduation project topic. If there are students who learn quickly, we will start their graduation project in advance."

I took classes for a while, and then when the next semester started, I started my graduation project, so it was a seamless transition.

This arrangement is very reasonable, and it will not disrupt the course schedules of students from freshman to junior year. There is relatively more room for adjustment in the senior year courses.

Gao Zhendong also knew that if they started from their freshman year, not to mention whether they could master the basic knowledge, he didn’t know how many years they would be able to work after graduation.

Gao Zhendong smiled and said, "Well, Dean Dai's arrangement is very thoughtful. Let's just push forward with this for the time being."

As for the preparation of teaching materials and other work, it will definitely be left to Dean Dai and others, and Gao Zhendong just needs to wait for class.

Gao Zhendong also informed Dean Dai that he was about to go on a business trip, asked for leave, and asked Dean Dai to arrange course adjustments in advance.

As for substitute teaching, no one can do it now, and no one dares to do it.

After finishing his talk with Dean Dai, Gao Zhendong turned around and went to Professor Liu. It was almost time for lunch.

"Professor Liu, you have to treat me to lunch today, haha." Gao Zhendong banged the bamboo stick as soon as he entered the door.

Professor Liu was also unambiguous: "Oh, it seems that the thing you mentioned has produced results? Bring it here, bring it here first and we'll talk later."

Gao Zhendong laughed, took out two round tin boxes and handed them over: "Try it, try it."

This thing is none other than a quick-loading drum magazine with a capacity of 75 rounds.

The cause of the incident was that when Gao Zhendong was communicating with Professor Liu, he was really unhappy with the 80-round drum magazine they designed.

They did remember Gao Zhendong's suggestion that the drum magazine could be used for both rifles and machine guns, but the drum magazine they designed was a bit weak.

It is basically designed according to the drum structure of PPsh41, except that the pistol bullet is replaced with an intermediate power bullet, and the size is modified accordingly. In order to be compatible with the magazine, a small socket is made for insertion into the gun. It is not unusable, but there are a few problems.

One, like the PPsh41, the bullet is facing upwards when loading. The problem is that the taper and aspect ratio of the rifle bullet are much larger than those of the pistol bullet. The original structure shook violently, resulting in a high feeding failure rate.

Secondly, it is rather troublesome to wind and unwind this thing. If it is tightened, you don't want to loosen it, and if it is loosened, it is difficult to tighten. Once the bullet is fully loaded, the spring is basically compressed.

The third is the problem of the socket. In the PPsh structure drum, the bullets are arranged in a single row inside the drum, but the socket part is in a double row. Moreover, the corner from the single row to the double row is quite large, which further causes poor ammunition supply.

Gao Zhendong played a few times and was really fed up with it, so he directly blackmailed Professor Liu: "Professor Liu, how about this, I will make you a drum, and you just need to treat me to a meal."
