Chapter 788: Monkey Version? See Chief Engineer Gao
If we don't bring this up, it will affect our own equipment. We should try to avoid this kind of thing if possible.

"Comrade Gao Zhendong? Do you want to develop a simplified version?" a leader asked with interest.

"Yes, it was him. He pointed out that the production capacity of the missile's seeker was too limited, which was not conducive to mass production. So he made this request to the research and development team at that time. Now it seems that his concerns were justified."

"He is worthy of being the actual leader. Although he is not in name only, he has not neglected anything. He is thinking ahead, so what about the situation of the research and development team?" If this kind of thing is brought up at the last minute, it will inevitably sound like shirking responsibility. However, if it is brought up in advance and coordinated with the actual difficulties encountered later, it would be foresight.

To be honest, the Defense Work Committee had no idea about the response of the research and development team. They were not interested in this kind of reverse behavior. They did not expect that this reverse movement would be impossible.

However, although he did not understand the situation, it did not hinder him from solving the problem at hand, because he remembered that when Gao Zhendong was first developing this missile, he had a plan that had low performance but also low price. However, the situation later developed very well and that plan was thrown to Java. Now he wanted to pick it up again, which should be no problem at all.

"The research and development team has selected and compared the early plans and picked a backup plan, but has not put it into follow-up work. If you want to use this backup plan as a model, there should be no problem." There is actually nothing wrong with this statement. In the early days, the Institute of Research and Development did do related work.

"Okay, then go back and organize some people to support this backup plan and do your best to support the struggle of Comrade Jiaozhi."

When Mr. Li, who was working on portable air defense missiles, received a call from the Defense Working Committee, he was confused. They had received the simplified version of the proposal, but had not had time to develop it yet. They also thought that this thing seemed unnecessary.
I didn't expect that we really need to do it now. Chief Engineer Gao's brain is really amazing. He always thinks ahead.

He took Lin Lianwei and went straight to the third factory. This matter seemed to be related to the guidance system, so he didn't bring anyone else.

When Gao Zhendong heard them talking about the need to develop a monkey version of an individual anti-aircraft missile, he almost died of laughter.

In fact, for Mr. Li and his team, making a monkey version is a piece of cake, but there is one thing they are not sure about, that is, how monkey should it be? Thinking that Chief Engineer Gao had already put forward this request, he probably has a scale in his mind, so they might as well ask him directly.

To be honest, Mr. Li and his colleagues are not unwilling to get equipment for others, but it requires them to spend a lot of energy on it, so they are not as enthusiastic as when they get it for their own people. So they just copy homework if they can.

"... Chief Engineer Gao, the problem is what I just said. We are not sure about it. Let me ask you to set the tone. How simplified should this simplified version be?"

Gao Zhendong shook his head: "No, no, we have to go in two directions. One is to simplify the materials of the seeker, and the other is to increase the complexity, which is the identification of friend or foe that I mentioned, so that the comrades outside will not be insufficiently trained and shoot down their own planes."

Look, Chief Engineer Gao is thoughtful. He simplified what needs to be simplified and focused on the core contradiction of the seeker material for simplification. However, for other places, what needs to be complicated remains complicated, fully considering the recipient countries.

"You talk, I remember." There's nothing much to discuss about this. Chief Engineer Gao can set the tone and the plan, and they can just implement it. It's simple and direct, and doesn't take that much time.

"The guidance head uses refrigerated lead sulfide. With refrigeration, lead sulfide can be used."

"But the head-on attack capability of refrigeration lead sulfide is very limited, right? And its anti-interference ability is also weak."

Gao Zhendong smiled and said, "Why do we need head-on attack capability to fight guerrilla warfare? Attack head-on, and then be discovered by the target or the target's friendly aircraft and get beaten up? Having tail-chasing attack capability, being able to ambush the enemy and threaten the enemy's retreat route after the attack, so that the enemy dare not launch an attack easily, is enough. As for anti-interference, give it an infrared filter and select the band that it transmits, which can more or less improve the anti-interference capability."

What he said made sense, but it was also somewhat specious. However, General Li and Lin Lianwei felt that it was true. For guerrilla warfare, carrying missiles and confronting head-on is undoubtedly not a good choice. Launching an attack from the side or rear is the most reasonable choice. Moreover, these two attack directions are enough to arrange tactics. Whether or not there is the ability to launch a counterattack is actually not a big problem.

As for the infrared filter, it is a stroke of genius. It is the lowest-cost and most convenient means of improving anti-interference capabilities. Although the effect is not particularly good, just say it, the cost is so limited, and this is already the best choice.

"As for guidance, cancel the single-chip microcomputer, remove the orthogonal four-element detector, and use a four-quadrant detector instead. Instead of using digital signals to control the missile, use analog circuits to simply compare the signal amplitude to control the direction of the missile. This way the cost can be reduced." The orthogonal four-element is a good thing, but it should not be leaked out for the time being. This thing is too good, so good that anyone can understand it at a glance.

Although to maximize its function, such as anti-interference ability, it needs the cooperation of single-chip microcomputer, Gao Zhendong does not even want to leak the incomplete version. If this thing falls into the hands of Jiaozhi people, it means it will fall into the hands of the Russians.

Moreover, portable air defense missiles have just been invented and there is no countermeasure against them yet. It is estimated that they will be enough to deal with the Citigroup helicopters within a few years.

Lin Lianwei writes very fast, and Lao Gao is reliable. They are very thoughtful about what should be simplified and what should be retained. "As for IFF, you can add it as you like. If you want to add it, the output of IFF should be mixed with the input of seeker demodulation. The former should have the effect of adjusting the parameters of the latter." It is equivalent to that without the output of IFF, the basic parameters of seeker demodulation will be problematic. In this way, IFF will be difficult to overcome. It can be said that the effect of forced IFF has been achieved without the control computer.

"This is a bit difficult." Lin Lianwei said with a smile.

Gao Zhendong nodded: "Yes, a little bit, so I said you can add more as you see fit. It's okay if there are none in the early stage. Comrade Jiaozhi doesn't have any planes for the time being anyway."

He hadn't said anything else. After being castrated like this, the performance of this thing would basically be unusable in ten or twenty years, so it didn't really matter whether to add it or not.

As for what Jiaozhi used in the later period to deal with the Citigroup helicopters equipped with infrared jammers, in fact, the performance of this thing is almost the same as that of the Russian Arrow-2B, and it is barely enough. The Arrow-2B also has some anti-interference capabilities, but not much.

Mr. Li evaluated it and said, "If we change it this way, the hit rate will probably drop a lot."

Gao Zhendong smiled and said, "The last time we attacked the helicopters on the plateau, the hit rate was only 33%. Do you think the comrades in the army have any objections?"

Huh? You can still compare them like this?
The three people present all know that there are special reasons for that hit rate. In fact, after the portable air defense bombs have been improved to adapt to the plateau, their hit rate far exceeds this number and is at the same level as in the lowlands.

But if you say that Gao Zhendong was wrong in saying this, that’s not true. The comrades in the army were extremely satisfied with the hit rate.

Seeing their entangled look, Gao Zhendong smiled secretly in his heart. The first thing the army would solve is whether it has it or not. You don't know how good they think the 33% hit rate is after being bullied. Besides, this thing is not for them to use, so they won't care much about it.

Moreover, when there were no jamming bombs, the hit rate of this plan was actually not bad at all. Gao Zhendong was very confident that it could reach over 60%, which was very good. It would definitely not damage the reputation of domestic weapons, and it would definitely be enough to make the Citigroup companies suffer. As for the later impact of jamming bombs, that was an inevitable result of technological development. Who would care?
In any case, General Manager Li and Lin Lianwei went back happily with the plan. Anyway, the plan proposed by Chief Engineer Gao gave them a backbone.

It’s not that advanced, but the effect looks good at first glance.

After seeing them off, Tang Shaohui arrived and his first step of work was completed.

He sat in Gao Zhendong's office, like an elementary school student who had just finished an exam and was waiting for the teacher to mark his paper.

What Gao Zhendong was holding in his hand was the test report for single-crystal silicon wafers that he had made according to Gao Zhendong's requirements. Oh, and there was also the test report for polycrystalline silicon.

Since it had been decided to develop monocrystalline silicon and polycrystalline silicon in two ways, the two were developed simultaneously.

"Well, not bad. These monocrystalline silicon wafers meet the requirements. We can move on to the next step. You have reduced the thickness to less than 0.2 mm, which is beyond my expectation."

"I happen to be working in this field and have some experience in this area." Tang Shaohui was very humble, but his tone was very confident.

Gao Zhendong nodded with satisfaction. As for polysilicon, that thing is a by-product in this step. As long as the single crystal silicon wafer meets the requirements, what needs to be done with polysilicon is to use the cutting technology of single crystal silicon to cut it into thin slices of the same size and thickness.

"We are going to make N+/P-type solar cells. You have already done the doping of the P-type substrate by doping boron in the single crystal furnace during the crystal pulling process, and the parameters such as doping concentration and substrate resistance also meet the requirements."

In fact, Tang Shaohui was very confused about how Gao Zhendong knew that the substrate resistance parameter had to be 10 ohms*cm to meet the radiation resistance requirements for space use, but Gao Zhendong didn't tell him about it, and he didn't dare to ask.

Gao Zhendong actually had no way to explain it. If asked, he would definitely copy it.
