Chapter 788 Monkey version? Look at Chief Engineer Gao
If you don't bring this thing up, it will affect your own equipment. This kind of thing should be avoided as much as possible.
"Comrade Gao Zhendong? Do you want to develop a simplified version?" a leader asked with interest.
"Yes, that's him. He pointed out that the missile's seeker production capacity was too limited and was not conducive to mass production, so he made this request to the development team at that time. Now it seems that his worries were justified. ”
"He is worthy of being the actual leader. Although he is not named, things have not fallen behind at all. He is thinking ahead. How is the situation in the development team?" If this kind of thing is raised only when the matter is about to happen, It is inevitable that there is a sense of prevarication, but if it is put forward in advance and it is consistent with the actual difficulties encountered later, it is prescient.
To be honest, the National Defense Work Committee did not understand the response of the development team. They were not interested in this kind of reversing behavior. They did not expect that the reversing now would be impossible.
However, although he did not understand the situation, it did not delay him at all from solving the problem at hand, because he remembered that when he first started working on this bomb, Gao Zhendong had a plan that although the performance was low, the price was also low, but the situation later turned out to be great. , that plan was thrown away in Java, and now I want to pick it up, and I think there will be no problem at all.
"The development team did a selection and comparison among the early plans and selected a backup plan, but did not invest in the follow-up work. If you want to use this backup plan as a model to be corrected, there is no problem." There is actually no problem with this statement. None. In the early days, the Institute of Guidance and Research really did relevant work.
"Okay, then you go back and organize the manpower, support this backup plan, and try your best to support Comrade Jiaozhi in his struggle."
When he received a call from the National Defense Work Committee, Mr. Li, who was engaged in portable anti-aircraft bombs, was confused. They had received the simplified version of the opinion, but they hadn't had time to do it yet, so they thought this thing was unnecessary, right?
I didn't expect that it would really be necessary to do it now. Chief Engineer Gao's brain is really unsatisfactory. He can think ahead.
He took Lin Lianwei and went straight to the third factory. This matter seemed to be related to the guidance system, and he didn't take anyone else with him.
When Gao Zhendong heard them talk about the need to develop a monkey version of individual anti-aircraft missiles, Gao Zhendong almost died laughing.
In fact, for Mr. Li and others, it is easy to make a monkey version, but there is one thing they are not sure about, that is how monkey-like this thing needs to be. Thinking that Mr. Gao has already made this request, Come to think of it, I have a good idea, so I might as well ask him directly.
To be honest, Mr. Li and the others are not unwilling to buy equipment for others, but if they have to spend a lot of energy on it, they are not as enthusiastic as they are to buy equipment for their own people. If you can copy the homework, just copy it.
"...General 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 seeker material, and the other is to increase the complexity, which is the identification of friend or foe that I mentioned, so as to prevent the comrades outside from insufficient training and putting themselves at risk." The plane was shot down.”
Look, Chief Engineer Gao is still thoughtful, simplifying what needs to be simplified, and grasping the core contradiction of the seeker material to simplify. However, for other places, what should be complicated must be complicated, and the recipient countries should be fully considered.
"You say it, and I'll remember it." There's nothing to discuss about this thing. Chief Engineer Gao will set a tone and a plan, and they can just implement it. It's simple and direct and doesn't take so much time.
“The seeker uses refrigerated lead sulfide. With refrigeration, it’s not impossible to use lead sulfide.”
"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: "What kind of head-on attack ability is needed to fight guerrillas? To attack head-on, and then be discovered by the target or the target's friendly aircraft, and beat him up? To have the ability to pursue the enemy, to ambush the enemy, and at the same time threaten the enemy's retreat route after the attack. Just make the enemy afraid to attack easily. As for anti-interference, get an infrared filter for it and choose the band it transmits, which can improve the anti-interference ability to some extent. "
What he said was reasonable and somewhat specious, but after listening to it, Mr. Li and Lin Lianwei felt that this was really the truth. For guerrillas, carrying a missile head-on is undoubtedly not a good choice. It is most reasonable to launch a strike from the side or tail. options, and these two attack directions are enough to arrange tactics. Whether or not you have the ability to attack is not a big problem.
As for the infrared filter, it is even more of a miracle. It is the lowest cost and most convenient way to improve the anti-interference ability. Although the effect is not particularly good, just ask if you have it. The cost is so much, this is already the best. Chosen.
“As for guidance, we can 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, we can use analog circuits to simply compare signal amplitudes to control the direction of the missile. This way, the cost can be reduced. "The orthogonal four-element is a good thing. Don't let it out for the time being. This thing is so good that anyone can understand it at a glance.
Although it needs the cooperation of a microcontroller to exert its maximum effect, such as its anti-interference ability, Gao Zhendong doesn't even want the incomplete version to leak out. If this thing gets into the hands of the Cochin people, it means it will get into the hands of Lao Maozi.
Moreover, the portable air defense missile has just been born, and there is no bonus period for countermeasures against it. It is estimated that within a few years, it will be enough to deal with Citizen's helicopters.
Lin Lianwei's writing skills are as fast as flying, and he is very reliable. What should be simplified and what should be retained? He has considered it extremely thoughtfully. "As for Identification Friend or Foe, you have to add it. If you want to increase it, then the output of Identification Friend or Foe will be mixed with the input of the seeker demodulation. The former will have the effect of adjusting the parameters of the latter." It is equivalent to no Identification Friend or Foe. Output, the basic parameters of the seeker demodulation will have problems. As a result, it will be difficult to overcome the identification of friend or foe. It can be regarded as achieving the effect of forced identification of friend or foe without controlling the computer.
"This is a bit difficult." Lin Lianwei laughed.
Gao Zhendong nodded: "It's a little bit, so what I said is that you can add more if you don't have one in the early stage. Anyway, Comrade Jiaozhi doesn't have any planes for the time being."
He still had something to say. After such a castration, the performance of this thing would be basically useless after more than ten or twenty years. It doesn't really matter if it is added or not.
As for what Jiaozhi will use to deal with the Citi helicopter equipped with infrared interference bombs in the later period, in fact, the performance of this thing is almost the same as Maozi’s Arrow-2B, and it is barely enough. The Arrow-2B is also somewhat anti-jamming. But not much of that.
Mr. Li made an assessment and said: "If we change it this way, the hit rate may drop a lot."
Gao Zhendong smiled: "The last time we used helicopters to fight against Zangsan on the plateau, the hit rate was only 33%. Do you think the comrades in the army have any opinions?"
ah? How can it be compared like this?
The three people here all know that there is a special reason for that hit rate. In fact, after the portable anti-aircraft missiles have been improved for plateau adaptability, the hit rate far exceeds this number and is on the same level as in lowlands.
But if you want to say that Gao Zhendong is wrong, that's not true. The comrades in the army are extremely satisfied with the hit rate.
Seeing their entangled look, Gao Zhendong secretly laughed in his heart. The first thing the troops should solve is whether or not they have it. You don't know if they think the 33% hit rate is so high after being bullied so hard. Besides, this thing is not theirs. If you use it yourself, they won't care much.
Check out the 16-9 book bar and see the correct version!
Moreover, when there are no interference bombs in this plan, the hit rate is actually not ugly at all. Gao Zhendong is still very confident about 60% or more. It is very good. It will definitely not ruin the reputation of domestic weapons, and it will definitely be enough for a Citizen to drink. Damn it. As for being affected by jamming bombs later, that is inevitable due to technological development. Who cares?
In any case, Mr. Li and Lin Lianwei went back happily with this plan. Anyway, they had the backbone of the plan proposed by Chief Engineer Gao.
It's hard to say how advanced this plan is, but the effect looks pretty good at first glance.
After sending them away, Tang Shaohui came, and his first step of work has been completed now.
He was sitting in Gao Zhendong's office, like a primary school student who had just finished an exam and was waiting for the teacher to mark the papers.
What Gao Zhendong is holding is the test report of monocrystalline silicon wafers that he produced according to Gao Zhendong's request. By the way, there are also polycrystalline silicon wafers.
Now that it has been decided that monocrystalline silicon and polycrystalline silicon can walk on two legs, those two things have been developed simultaneously.
"Well, yes, these monocrystalline silicon wafers meet the requirements. We can move on to the next step. You have made the thickness less than 0.2 mm, which is really beyond my expectation."
"I happen to be working in this direction and have some experience in this area." Tang Shaohui was very modest, but his tone was very confident.
Gao Zhendong nodded with satisfaction. As for polycrystalline silicon, that thing is a by-product at this step. As long as the monocrystalline silicon wafers meet the requirements, what polycrystalline silicon has to do is to use monocrystalline silicon cutting technology to cut slices of the same size and thickness. That’s all.
"What we are going to do is an N+/P-type solar cell. The doping of the P-type substrate has been completed by doping the boron element in the single crystal furnace during the crystal pulling process, and the doping concentration, substrate resistance, etc. The parameters also meet the requirements.”
In fact, Tang Shaohui was very confused about how Gao Zhendong knew that the substrate resistance parameter must be 10 ohms*cm to meet the radiation resistance requirements for space. But Gao Zhendong didn't tell him about this, so he didn't dare to ask.
Gao Zhendong actually couldn't tell, so he just copied it if he asked.
