Chapter 751: Which star does one star do?
Although the personnel adjustment is a big move, for Gao Zhendong himself, there has not been much change. The third factory is still the third factory, and the daily production and administrative management are all undertaken by others. It’s just that it was Yan Chengde before, and now it is Just Zheng Liangshu.
Gao Zhendong's main work recently is still reading chemistry books. That expensive paper is a completely new field for him. The paper is relatively in-depth and the results are new, but it is not based on a completely new theory. He can't always do it on his own. I just threw it out without even understanding it.
This is different from the previous groundbreaking things. Those things can be made up as he likes. At most, they are just what he got in a dream, and they can also become a good story.
But this doesn't work. If you take it out rashly and you don't understand it, it's going to be a joke.
"...Using malononitrile as the initial raw material..."
"...the first intermediate is monoclinic..."
"...The third intermediate is in the triclinic system after recrystallization from ethanol..."
"...The synthesis route is..."
For Gao Zhendong, whose mind is full of electronics, metal materials, computers, and software, this is a big challenge, especially when he cannot extract relevant teaching materials from the system and wants to understand it. This thing still requires a lot of effort.
There is no way to extract textbooks from the system. First, because they are too expensive. Even if he looks at such things, they don’t exist. Secondly, chemistry is really far away from his major. Those such as inorganic chemistry, organic chemistry, etc. He has never read most of the professional basic textbooks on chemistry, electrochemistry, analytical chemistry, physical chemistry, structural chemistry, etc., and cannot mention them at all.
Fortunately, in chemistry, the basic theory has not developed much. With these days' college chemistry textbooks, you can still more or less verify and absorb some. As long as it reaches a certain level, you can fool people.
At least it can be deceived, so I can take it out to Mr. Xiang and others who are engaged in urea technology and engineering plastics to take the next step. Otherwise, if this thing is thought up out of thin air, absolutely no one will believe it.
As for whether Mr. Xiang is familiar with this branch, that is another question. He is not familiar with it, but he can find someone who is.
The paper is divided into several parts. Another part is another thing, another synthesis route, and Gao Zhendong still needs to gnaw on it.
While Gao Zhendong was resting, the phone rang.
The call came from the National Defense Working Committee: "Comrade Zhendong, please come to the National Defense Working Committee immediately. There is an important temporary meeting that you need to attend together."
Gao Zhendong put away his papers, got in the car and rushed to the National Defense Work Committee.
While Gao Zhendong was still on the road, in a conference room, the leader of the National Defense Work Committee, the chief engineer, and several comrades were discussing things.
"Leader, Gao Zhendong has never been exposed to this direction before, right? Doesn't it make sense to invite him?" the chief engineer asked.
"At least he knows something about the Rockets, and he has a good mind. If it's a question of whether to do it or not, it's not necessary to ask him to come. But to discuss the issue of what to do, inviting him to come may bring some different gains. .”
When Gao Zhendong rushed to the National Defense Work Committee without stopping, he saw this scene. Everyone had several reports in front of them. They seemed to be similar things. They should be making some arguments or discussions.
Seeing Gao Zhendong's arrival, the leader pointed to an empty chair: "Zhendong, sit down and look at this."
After saying that, he handed a set of materials in his hand to Gao Zhendong. It seemed that he didn't expect that he would need to participate in the meeting, but for some reason, he still called him over.
Gao Zhendong turned his attention to the material in his hand, and his eyes widened when he saw it.
"Preliminary Thoughts on the Development of Artificial Satellites"
"Recommendations for Starting the Artificial Satellite Project in Advance"
"..."
These are several proposals for the development of artificial satellites. Although the names of the reports are different from those known in previous lives, the names above are still very familiar to Gao Zhendong. They are familiar and famous.
The reason why Gao Zhendong's eyes widened was because this matter was brought forward too early. Originally, we proposed the satellite very early and had the idea in 1958. However, due to economic, technical and other reasons, it was not officially launched until 1965. , it took 70 years to launch. However, our satellites are not developed one after another. In fact, the research on the second satellite has been started long before the first satellite was launched into space, so the second satellite was launched into space relatively quickly. And the structure and mission are very different from the first one.
It’s only 62 years now! But Gao Zhendong thought about it carefully, and it seems to be similar. What he knew in his previous life was that he only started working on satellites after Miss Qiu left the cabinet. If calculated according to this node, it seems that it is not too outrageous to start considering it now?
Gao Zhendong quickly browsed through the materials. The leaders and comrades on the side were still discussing this topic.
He put down the material and listened for a while.
The leader took advantage of a gap in his speech and turned to ask him: "Zhendong, what do you think after reading this?"
Gao Zhendong shook his head: "Not yet, but now it's decided to do it?"
The leader also shook his head: "Not yet. We are discussing various aspects now. Other things such as rockets, launches, telemetry support, etc. are all being discussed. Today's discussion is about the function of the satellite itself. You have a bright mind and a lot of ideas. It’s a coincidence, so I called you over and listened together.”
Only then did Gao Zhendong understand that this was part of the preliminary planning work. He didn't rush to speak, but listened to what others were saying.
"I think that the first satellite should not be responsible for scientific research tasks. The main purpose is to prove that we can launch satellites into the sky and maintain normal operations for a period of time."
"Proof? How to prove it?"
"I'm thinking about summarizing it into a few points. It can be fought, heard, and observed."
Hearing this comrade's idea, Gao Zhendong almost laughed out loud. This idea was really similar to the later requirements of the first man-made satellite to "can be climbed up, grasped, heard, and seen." It was just that the satellite The "catch" aspect of telemetry has been put aside for now.
"Spending so much money just to hear a sound?" Some comrades still have some doubts.
"If you can hear the sound, it proves that the technology is effective."
"I think we still need to carry some mission payload up there, as resources are limited."
"..."
Seeing that Gao Zhendong had been listening for a long time and was slowly getting into the mood, the leader turned around and asked Gao Zhendong: "Comrade Zhendong, what do you think?"
Gao Zhendong thought for a while, and he knew a little about satellites, which are closely related to the military.
Read the error-free version at 69 Book Bar! 6=9+Book_Bar debuts this novel.
"If it's a long-term plan and a series of satellites are planned, everything can be done, but the first one... probably can't do much. Communication satellites are usually in synchronous orbits, and that orbit is too high. The first It’s unrealistic to shoot it that high.”
The height of the synchronous orbit is tens of thousands of kilometers. It doesn’t take a lot of thinking to figure out that it is impossible for the first rocket to hit that high.
Although Gao Zhendong said this, other comrades knew as soon as they heard that this comrade knew about satellites. If he could tell about the synchronous orbit in one sentence at this time, he could definitely be regarded as having a good understanding of satellites.
Gao Zhendong continued to express his thoughts: "For the same reason, broadcasting satellites and the like are actually not suitable."
Although our first satellite broadcast music in space, it is not considered a broadcast satellite in terms of type. Broadcasting music is just a way for it to prove its existence. In fact, the satellite does not have the actual function of a broadcast satellite.
At this point, Gao Zhendong knew what he should do.
"Dear leaders and experts, if you want to say what function the first satellite will undertake, I can't say. Sometimes the first satellite is not entirely due to technical considerations. But I have some ideas about what the second satellite will do."
The leader was amused by Gao Zhendong's cunning statement: "Then let's talk about the second one."
Gao Zhendong said: "For the second one, I suggest it be turned into a test satellite to test the power supply system, basic outer space environment detection, telemetry system, etc. Starting from the third one, we can consider returnable satellites or camera satellites At the same time, we can also start to consider placing satellites in geosynchronous orbit.”
Regarding the idea of building a geosynchronous orbit satellite, Gao Zhendong has not considered the big task of installing a global satellite positioning system for the time being. Our satellite positioning system covers far more orbits than geosynchronous orbit. This thing is really not something we can handle now, but with communication satellites, it is possible. The geostationary orbit that communication satellites stay in is a type of synchronous orbit.
Even if geostationary orbits cannot be launched, it does not seem impossible to launch several photographic reconnaissance satellites in low orbits.
Although it took a total of five years from 1965 to 1970 to put the satellite into the sky, in fact, our satellite really entered into detailed design in 1968, and the speed was still very fast.
If you're lucky, maybe you can still use it? Gao Zhendong thought in his heart.
"Taking photos?"
"Yes, photography, whether it is a return film compartment or remote transmission, as long as the camera resolution and transmission speed reach a certain threshold, photography is useful, such as for crop yield estimation, disaster prevention and mitigation, land and resources survey and evaluation, etc."
Gao Zhendong said it seriously. This is not what I said. I heard it said so on TV in my previous life.
The leader of the National Defense Work Committee almost laughed when he heard this. This kid is quite tricky. He knows that he is telling lies with open eyes, but it is not all lies. These aspects can really be used.
"To buy such an expensive thing, just read these contents? To estimate the yield of crops, comrades who rely on agricultural exports can do it."
"Then make it a transmission type. Then you can do more things." Gao Zhendong was still serious.
"Can our communications technology hold up?"
"Sometimes, even if you can only upload one photo a day, it can play a big role, such as disaster assessment..." Gao Zhendong came up with disaster prevention and reduction.
“And when it comes to transmitting photos, it’s not just the communications technology that can affect performance.”
