Chapter 322: Lao Yu, Let’s Do Our Old Business First

The words were so urgent and the tone so certain, it was as if he was afraid that the 17th Ministry of Machine Building might mishear a word.

There's no way, this thing is just too tempting.

As we all know, we were able to push 17 countries back to the 38th parallel a few years ago. In addition to command and organization, our traditional close combat and night combat tactics also played an indispensable role.

At that time, the Citibank guys had almost reached the point where they would get headaches every night and would get cramps when they heard the charge.

The Citigroup guys later even equip themselves with individual night vision goggles that cost $70 a pair. This should be attributed to the psychological trauma caused by the beating at that time. Of course, the "Specialist Smith" and others also played a significant role in this.

It hurts so much, brother!
The leaders of the Defense Work Committee are very clear that the advantages gained from hard training and excellent organization are being slowly offset by the development of technology. One day, if we do not catch up in technology, this will undoubtedly become a disadvantage for us.

The sentence "initially intended for line-scan thermal imager imaging sensors" in this thing is enough to make people excited. He has never heard of a thermal imager, but the meaning of this term is so clear that even if he has never heard of it, he can understand what it is when he hears it for the first time.

This is the beauty of the Chinese language. Even if it is a new thing, I can give it a name that is easy to understand using simple and beautiful language.

In addition to the advantages such as multi-band coverage, operation in strong radiation environments, etc., you’d be a fool not to want this thing.

The other party sighed and said, "Okay, I'll approve it right away."

Hmm? Something is wrong! Hearing this sigh, the leader of the Defense Work Committee immediately realized that there seemed to be something extra in it.

Coming out of his excitement and thinking deeply, he immediately realized that something was wrong.

Although the 17th Ministry of Machine Building is not responsible for equipment, it must be able to see the significance of this material. In this case, it still needs confirmation from its side before approving the plan. This is interesting.

By the way, what he said earlier was very interesting, “If you think you can slow down a bit,” then “I’ll just suppress it.”

This illustrates two problems.

First of all, he was sure that the Defense Work Committee needed it, it was just a matter of sooner or later.

Secondly, he will definitely approve this plan, the only difference is the time.

It seems that there is something. The Defense Work Committee couldn't help but ask: "Old Y, what's the problem? From what you said, it seems that things are not going smoothly?"

The 17th Ministry of Machinery did not hide anything: "Nothing, this thing was proposed by Gao Zhendong. The reason why we wanted to slow down at first was that we felt that he had too many things to do and wanted to give him some time to rest. But you can see that this thing is really important, so we'll arrange it according to work needs first."

The defense committee suddenly realized what was going on and immediately changed their minds: "Then let's just slow down."

Having said that, I can’t go on.

Is slowing down useful? No!
Given Gao Zhendong's personality, if you don't approve this matter, he will definitely be able to find another job to fill it.

The Seventeenth Ministry of Machinery heard this and laughed: "How is it? You know my difficulties, haha."

“It’s difficult!”

Upon hearing this, the 17th Ministry of Machinery comforted him: "Don't worry too much. I've seen that the specific implementation of this project is in charge of another unit of ours, and Gao Zhendong is only responsible for leading it. Judging from his habit of working on previous achievements, he has probably finished the principle design part at this point in time. It doesn't make much difference to him whether he takes it slow or not."

This is true. This is how single crystal furnaces work. According to the information obtained by the 17th Ministry of Machine Building, after the project was launched, except for the most important principles and original design parts which Gao Zhendong had already come up with at the very beginning, most of the other specific matters were done by other comrades led by him. Unless there were problems, Gao Zhendong did not intervene much.

In other words, apart from temporary topics such as anti-tank missiles, Gao Zhendong was tinkering with things like single crystal furnaces and tungsten-molybdenum alloys. When Gao Zhendong proposed this project, things were actually almost completed for him.

The two laughed on the phone and thought, forget it, there's no point worrying about it. At least Comrade Gao Zhendong looks healthy and can eat three big bowls of rice in one meal in the cafeteria.

His wife is going to take the medical exam, so they will be more relieved when she graduates. These two old comrades have already started to place their hopes on things to happen four or five years later.

No matter what, this matter was approved very quickly - agreed.

Holding the department's documents, a key member led by Yu Yuncheng laughed and said, "People are different. Director Gao's application is simple. He didn't even explain the process. It's almost the same as just writing a name and an introduction. He approved it. I admire you."

Yu Yuncheng laughed: "If you have the achievements that Director Gao has, don't worry, even if you just write a few words on a piece of paper, they will still approve it."

"I don't have it, so it looks rare, hehe."

"You know there is no solution, but you still don't get to work! Notify your family so they can make preparations." As for himself, he still needs to communicate with Gao Zhendong about the next step of work. Up to now, he himself doesn't know how to do it.

Seeing him coming over with the report on mercury cadmium telluride, Gao Zhendong smiled and said, "Approved? Then let's do our old job for a few days, pulling crystals."

Yu Yuncheng was a little surprised: "Isn't this thing difficult to handle? Can it be pulled directly?"

Gao Zhendong smiled and said, "That's great. First, pull out a batch of quartz tubes to use as test containers."

The production of HgCdTe bulk crystals basically cannot be separated from this step. First, seal the whole material and make HgCdTe polycrystals. If it is not sealed, you can't even make HgCdTe polycrystals.

The method chosen by Gao Zhendong is more extreme. All subsequent operations, before qualified crystals are formed, are performed on this sealed tube.

What could withstand the high temperatures and mercury vapor pressure during the manufacturing process? Without introducing other strange impurities? And what would be better, transparent for easy observation?
After looking around, it's you.

——Silicon dioxide.

So the first step in making mercury cadmium telluride is to get some high-purity silicon dioxide crystals to make quartz tubes.

Can it be bypassed? Maybe. Is it costly? Is it effective? That's hard to say. Why do people choose this method on this technical route? There is a reason for that.

As for the specific crystal pulling process of mercury cadmium telluride crystals, the single crystal furnace is of no use. The main reason is that the current single crystal furnace uses the CZ direct pulling method and cannot pull mercury cadmium telluride single crystals.

Institute 1761 does not have a single crystal furnace yet, so this matter naturally has to be done at the Third Rolling Mill for the time being. Fortunately, pulling this thing is easy for Yu Yuncheng and it doesn't take much time.

Yu Yuncheng didn't ask about what happened next. He took the specifications of the quartz tube, called his people, and went to pull SiO2.

This familiar feeling came back again. When Director Gao gave instructions, he was always clear about the goal and cut out the details, as if he knew that this path would definitely succeed.

After seeing off the happy Yu Yuncheng, Gao Zhendong started to busy himself with his own affairs.

Now that the single board computer is done, you can put it aside. This thing is very useful. Just find ways to increase production capacity and reduce costs. You don't need to worry about it for now.

The rest of the software improvements will naturally be taken care of by our colleagues at the Computing Institute. As for the capacity expansion itself, we are working on it with Factory 1274. Fortunately, although the Gallic Roosters were weakened by the war, they are still doing solid business.

Crying Country: What did you say? Really? All five missiles were detained.

This requires us to point out that the gap between countries is sometimes even greater than the gap between people.

I have been writing an operating system at home. It is multi-user, multi-tasking and network-based, which is quite time-consuming.

So at this time, what Gao Zhendong was actually doing at work was dealing with missiles and barrels.

Fortunately, the missile engine drawing has been almost completed. After the Changjian Factory verifies the propellant, Gao Zhendong will be able to determine what the grain in the engine will look like.

The main thing is that although we know the formula and the approximate performance, no one knows whether there is any difference in performance between the X12 we make and the X12 made by Citigroup. This thing is also closely related to the process.

Different combustion temperatures, burning rates, and explosion heats make a big difference in engine design and charge shape design.

The current hair fixation is determined according to the performance of the original X12 on hand. Maybe when the homemade X12 is developed, these things will be modified to a certain extent.

So Gao Zhendong turned to something else - the warhead of the tube.

He did not make any modifications to this, but directly copied the shape and size of the 89 barrel. Although there was no clear size, he did have the total length data of the 89 bullet and the front and side section photos, which allowed him to infer the size of the warhead to be almost accurate.

Gao Zhendong only drew the warhead itself. As for some connecting parts and fixing pins, he did not draw them. Although these things may look simple, they are closely related to actual production and use. His own design is not as good as that of Changjian Factory.

His idea was simple. He would just make this thing. If its power met expectations, he would leave the above-mentioned miscellaneous matters to the Long Sword Factory. It was estimated that the Long Sword Factory would be more than happy to have such a thing.

Developing an anti-tank missile and giving birth to a baby at the same time, who wouldn't be happy about that?

The drawing was done very quickly, and then Gao Zhendong called Liu Rongguo. He had already burned the electrodes of the double platinum-rhodium thermocouple, and Lao Liang was doing the assembly and testing of the thermocouple, so Liu Rongguo had some time.
