Chapter 178 Superconducting Magnetic Fluid Propeller
“Tianmin, does Guangshen usually write like this?”
Zhou Jin is Lin Tianmin’s college roommate. He is aiming to go to Yanda University because of the postgraduate entrance examination. It took two exams before landing.
The one who finally came ashore was not the Yanda headquarters, but the Yanda Pengcheng campus. At this time, he had just completed a two-year postdoctoral period and joined Shenhai University as an outstanding young teacher in a three-year program that was either promoted or left.
After Lin Tianmin graduated with a doctorate from Yanjing University of Aeronautics and Astronautics, he joined Guangjia Aerospace. Guangjia Aerospace was first located in Shenhai, and later moved all research and development to Pengcheng.
Because after the normal temperature superconducting incident, everyone moved back to Shenhai from Pengcheng.
Going round and round, their roommates reunited in Shenhai, and the two of them interacted very frequently.
Lin Tianmin didn’t quite understand what the other party meant: “Juan?
Guangshen, of course Juan, the King Juan I saw in college was a salty fish in front of Guangshen.
He The most exaggerated thing is that he not only drew the drawings, but also made the drawings very efficiently." He recalled that Chen Yuanguang spent two weeks drawing the power system of the Pioneer 2.
This incident subverted his worldview in a sense. He had always felt that we were in an era of highly divided labor, and no matter how awesome you were, you had to rely on the power of the organizational structure.
The academic management function of a professor is greater than his research function.
Until Chen Yuanguang appeared, the drawn power system solved all the problems they had encountered before, and even took into account the current supply capacity of China's aerospace industry.
In the internal system, which designs will be optimized in the future as material performance improves, and subsequent optimization ideas are marked.
Lin Tianmin felt that this was not something that humans could do. If it were him, he wouldn't be able to do it in two weeks, let alone two years.
So when Zhou Jin mentioned it, Lin Tianmin quickly thought of this past event.
“Why are you asking this? You don’t want to stay in college, but want to work in Guangjia Aerospace?
Although our threshold has been rising rapidly in the past two years, you shouldn’t have much problem in coming. "
Zhou Jin shook his head: "No, didn't you watch your boss's live broadcast yesterday?"
Lin Tianmin said: "Of course you did, that live broadcast was not about natural fund applications. What?
Some of our colleagues asked Guangshen in the work group whether they could apply for their project? "
Zhou Jin became interested: "What did Guangshen say? "
Lin Tianmin said: "Of course it's not possible. Guangshen said that the company has a high degree of interest entanglement with him, and if he needs funds, he must apply directly internally. Our funds are sufficient. "
Zhou Jin: "Of course, perovskite is a cash cow, constantly creating value for you, not to mention there are a lot of investors waiting to invest money in Guangjia Aerospace. Now I heard that only state-owned assets Can get in. "
" Opponent, didn't Guangshen say something good yesterday? Even the source of the topic was pointed out to everyone. Those major issues were not chosen by him, but by the Science and Technology Committee.
Apart from the excessive personal power in the process of distributing funds, there don’t seem to be many problems. Lin Tianmin said: "Considering that Guangshen is not short of money and there is really no selfishness, this issue can be ignored."
The worst consequence is that money invested has no results, but most of the results of current natural funds are of limited value. "
Zhou Jin said: "You are right, what I want to express is Juan. After I listened from beginning to end yesterday, I heard one word, Juan.
In the group of our colleagues, including some Qingjiao, everyone is discussing this matter. One person said it very well. He said that the God of Light is like One Piece. Yesterday, I told everyone in the live broadcast that my treasure will be put there. Among the major issues of the Association for Science and Technology every year, if you want to go get it.
Let everyone enter the age of navigation and tell everyone that if you win the lottery, you will have an advantage when applying for funds next year and have a stable source of sponsorship funds.
But the problems to be solved are also more difficult than ever. I took a look at the problems related to me.
How to break through the application of carbon fiber composite materials in my country's future ultra-high-speed rail transit vehicle equipment?
How to leverage the advantages of my country’s information and communications industry to quickly achieve breakthroughs in chip technology and industry?
How to develop the high-end technology of petroleum-based carbon materials?
How to realize space-borne lightweight deployable array antenna through flexible film technology?
These all belong to the category of materials science. The question is, can I do it? If I can solve it, let alone a teaching position, I should be given an academician position. "
Lin Tianmin said in confusion: "Didn't it say it can be disassembled? You can choose relevant topics and slowly move towards the final goal, breaking down difficult problems. "
Zhou Jin said: "Yes, it can be dismantled. The problem is, doesn't it mean that everyone enters a five-kilometer runway together, and then checks each fifty-meter level, and then filters them layer by layer. In the end, there may only be that If one or two people can reach the finish line, 99% of people will be eliminated.
The previous Nature Fund was a 100-meter running track. Everyone competed to qualify for the sprint. Once you are qualified, you only need to finish the race within the specified time.
Now it’s a long-distance run, and it’s a long-distance run with one screening every 50 meters, forcing everyone to roll up, which is a bit too rolled up.
And it is obvious that the topics chosen by Guangshen should be understood by himself, and there are only a few topics, and then everyone will start taking these topics from the first year.
The progress is advancing every year. If latecomers want to apply and squeeze in, others have already finished. If you want to apply again from the third year, the difficulty will be further increased. .
In short, Guangshen has turned this into a long-distance race that runs throughout the researcher’s entire academic career.
To put it nicely, it’s called long-distance running, but to put it badly, it’s called cultivating gu.
Sure enough, it’s really good. ”
Lin Tianmin smiled and said: "Didn't Guangshen say at the beginning that this fund is to solve major problems? I think only in this way can we cultivate scholars who can solve major problems."
Zhou Jin : "You are right, but what everyone is complaining about is that after the rules of the game have changed, the threshold has been raised. In the past, you might have been able to relax for a while after applying, but now it has been a test.
I feel that Guangshen Making the subject application more difficult
And I heard that if this mechanism works well, it will be promoted in the future, and the academic environment that is already difficult will be further exacerbated. ”
Lin Tianmin said: "Next time you have a meeting with your boss, I can help you react and ask him what he thinks." Zhou Jin said: "As long as you don't poke me out, just say you are listening to you." A friend said it.”
After this statement reached Chen Yuanguang’s ears, he replied: “Tianmin, I don’t think so, I think this is cultivating a habit.
There is pressure for sure. , but my method will even out the pressure and give you motivation instead of phased.”
Lin Tianmin told his roommate Chen Yuanguang’s reply simultaneously, and Zhou Jin was silent after listening. Said: "Maybe.
I think only time can give us the answer.
I recently went to inquire around again, and it seems that only those who are confident enough that they can win in this long-distance race have applied for Guangshen's fund.
Everyone believes that if we can get long-term funding from this fund, even if there are no results, it will be equivalent to receiving the blessing of the God of Light, and we will have more confidence in the hospital. "
"Others rely on the confidence brought by their papers, do they rely on the confidence brought by the God of Light? Lin Tianmin joked.
“That’s right. ”
At this time, Chen Yuanguang has returned to Mianyang, and a large group of people are waiting for his return.
This is a task assigned to him by the boss, and I hope he can help with some suggestions.
"Mr. Chen, I have long admired you. My name is Hu Xinrui, and I am the person in charge of the superconducting magnetic fluid thruster.
You should also know that the international situation has been turbulent in recent years. We hope that Enhance national defense strength as much as possible
After room temperature superconducting was prepared by you, we quickly realized that we could use room temperature superconducting technology to create superconducting magnetic fluid thrusters and apply superconducting magnetic fluid thrusters to submarines. , which can greatly enhance our strategic deterrence capabilities.
The navy and local research institutions have always had magnetic fluid propeller projects.
Because in the past, superconducting materials required extremely low temperatures to achieve a superconducting state. Then considering that different superconducting materials have different critical temperatures and critical magnetic fields, we also need to screen out superconducting materials suitable for engine needs.
The biggest difficulty is that the efficient superconducting magnetic fluid thruster generator needs to optimize the thermal energy conversion efficiency and ensure the stable production of magnetic fluid. It must avoid magnet quench caused by thermal disturbance, mechanical vibration and other factors. The maintenance of low temperatures makes it very difficult to do.
The energy consumption reduced by superconducting magnetic fluid thrusters is far lower than the energy consumption required to maintain ultra-low temperatures.
So the previous superconducting magnetic fluid thrusters have always stayed in the laboratory stage, and there is a long way to go before practical use
After the emergence of room temperature superconductivity, its practical application became possible , we quickly initiated the project after completing the feasibility study internally, hoping to develop it as soon as possible.
The biggest naval gap between us and our opponents has always been in the underwater fleet. We have always lacked high-quality nuclear submarines.
The level of silence of our nuclear submarines is comparable to that of the Damao submarines of the 1980s.
Superconducting magnetic fluid thrusters will completely reverse this trend.
Furthermore, once superconducting magnetic fluid thrusters are applied to submarines, it means that we will no longer have any interference and can catch all opponents off guard. "
Chen Yuanguang was speechless. Why did you, an old man, start to wutong while talking? Weren't you all fine before? Are you discussing passive defense of strategic deterrence? Why are you suddenly going to launch a strategic attack?
If he knew American's strategy, he would think that this was a two-way journey in another sense.
“But after we established the project, we found that its development was far more difficult than imagined.
Theoretically, although GJ01 is a one-dimensional superconducting material, it can be used in superconducting magnetic fluid propulsion On the machine, at least the cooling system of the superconducting magnetic fluid thruster can be greatly simplified.
Only a simple constant temperature system like that of a Xiaomi car is enough.
Reducing the system. Complexity also means improved stability. The simpler the design, the more stable it is.
Then in the preliminary preparation work, we discovered that although GJ01 is a one-dimensional material, it can generate a uniform and strong magnetic field in a three-dimensional space through a specific arrangement and combination.
Recently we have discovered that there are still a lot of difficulties that cannot be solved.
The shackles of one-dimensional superconducting materials still cannot be broken. Mr. Chen, we need your help. "
After listening, Chen Yuanguang only asked: "Mr. Hu, do you really know how to wutong?" ”
There are so many stories about the boy who cried wolf that Chen Yuanguang really doesn’t believe it.
Chen Yuanguang felt that the other party's answer was directly related to his enthusiasm. If he really did it, he would definitely maximize the efficiency and design a superconducting magnetic fluid thruster for it.
You must know that once it ends, even if it is only a regional low intensity, it will be the most important thing in the first half of the 21st century.
The fate of the whole of Asia will be decided, and it won’t be enough if we don’t work hard.
If you don’t want to do it, you just indulge in lip service, and the strategy is beaten after you come up with the research, then you can only passively slow down the work and research passively.
Hu Xinrui murmured: "I guess, I am doing research alone, how can I know such a thing.
I'm just talking about its possible application scenarios. "
There was no momentum before.
Chen Yuanguang thought to himself, it is indeed the case, "Oh, I thought you had some source of information.
It turns out that the wind direction has not changed yet. ”
