In Beijing, in a conference room.

There were many people sitting in this conference room, including officials from the Ministry of Science and Technology, officers with epaulettes on their shoulders, academicians of the Academy of Engineering, and experts in the field of aerospace.

One inch-thick copy of the conference materials was placed on the conference table in front of them.

At the top of the conference materials is a paper with a prominent title.

Application Prospect and Technical Feasibility Demonstration of Controlled Fusion Miniaturization Technology in the Aerospace Field

For the application of miniaturized controllable fusion reactors in the aerospace field and the Hall thrusters associated with them, the paper has made a certain professional description, and demonstrated the possibility of its technical realization with rigorous calculations.

However, the demonstration of the technical feasibility that has not yet been realized is itself subjective.

Not to mention this concept of being ahead of its time......

"It's nonsense!"

Putting down the paper in his hand, Academician Wu shook his head and criticized unceremoniously, "Just looking at the impulse, the electric thrust is indeed much stronger than the chemical thruster, but the thrust is a hard injury that cannot be solved!" ”

"Don't talk about anything else, as far as the VX-200SS ion engine that was completed by the Fourth Academy of Aerospace last year is concerned, the power can be 200K, and the total thrust is only 5N! Even if he can multiply it a hundredfold, a thousandfold, he can use this thrust to push the spacecraft into low-earth orbit? It's enough to send an egg up! ”

"I think the person who wrote this paper simply didn't wake up in his head!"

"If you can send satellites from the surface of the earth to the sky, even Qigong can shoot satellites!"

When Mr. Wu said this, the atmosphere in the conference room was a little awkward.

Although I know that this old scientist's temper is like this.

But this thing is qigong......

Can you stop mentioning it?

The expression on the face of the leader of the Ministry of Science and Technology was a little unbearable, but the old man sitting next to him didn't care, just said thoughtfully: "Can't it be solved?" ”

Academician Wu shook his head and said, "It basically can't be solved!" ”

As for what controlled fusion miniaturization, he doesn't know much and doesn't want to comment.

No one can say what the technology of the future will be.

The earliest nuclear fission batteries had to be the size of a small house, and no one expected it to be used in spacecraft when it was first built.

However, in just a few years, in the 70s, the problem of miniaturization was properly solved. Until now, the smallest can even be the size of a five-cent coin (1.95 centimeters in diameter, 1.55 millimeters thick, and the volumetric energy density is about 1 million times that of ordinary chemical batteries).

However, the success of the demonstration reactor on Haizhou has only been more than three months old, and now they are planning to install the reactor on the spacecraft, and most of them are also bragging.

Hearing this old subordinate devalue this paper as worthless, Ren Changming's expression was also a little embarrassed, so he made a round.

"The ideas put forward in this paper are indeed a little optimistic, and I admit that it is indeed difficult to achieve the level that is stated in this paper, but I don't think this difficulty is completely unsolvable, right?"

"You have been away from the front line of scientific research for too long, I don't reason with you about this," Academician Wu waved his hand and pointed at the paper with his index finger, "Who wrote this paper?" You come to him, and I'll reason with him face to face! ”

Hearing this, Ren Changming was out of line.

exchanged glances with the leader of the Ministry of Science and Technology, as well as the old man sitting next to him, and Xu Yuanming, who was instructed, coughed lightly and said loudly.

“…… It was written by Chief Designer Lu. ”

There was silence in the conference room for a while.

The silence is terrible.

Mr. Wu's expression was a little slightly embarrassed, and he reached out and picked up the paper again.

“…… I'll think about it again. ”

After a while, he made a blank expression and took the steps of controlled fusion miniaturization, which had not been commented on before, and said with his head buried in his thoughts.

"Ahem, I seem to have missed a few places just now. Electric propulsion, whether the thrust can be increased or not depends on the power. It's really impossible to use traditional nuclear batteries, power and power are a hard flaw, but fusion batteries are really hard to say, hard to say......"

Xu Yuanming: "......"

Everyone in the room: "......"

Any project must be reviewed by a panel of experts, even the winners of the Nobel Prize and the Order of Lingyun.

However, it is not easy for such academic giants to find someone to review their projects.

The class boundaries in the domestic academic community are obvious, and it is taboo to openly comment on people with higher connections, status, and academic prestige than themselves.

It was because they were worried that this would happen that they deliberately withheld the name of the author of the paper.

But no one expected that Mr. Wu, who usually argues that even the former chief designer of the lunar exploration project, would not be able to identify his position after hearing that the author of the paper was Professor Lu.

But judging by his previous reactions, this thing should be really difficult to do.

Otherwise, his reaction would not have been so strong.

At this time, a man with epaulettes on his shoulders who had not spoken before spoke with a serious expression.

"Can I share my opinion?"

Old man: "Please speak." ”

The man paused and continued: "I don't know much about aerospace things, so I won't comment here. However, I think that even if we put aside such things as Hall thrusters and electric propulsion rockets, this research on the miniaturization of controlled fusion is quite necessary. ”

"According to the description in this paper, if the controlled fusion miniaturization technology can really be realized, its application field may not only be installed on spacecraft, but also on our submarines and even aircraft carriers."

Hearing this, the expressions of many people present became serious.

After a moment of silence, the old man nodded.

"You're right, whether it can be technically realized or not, even if you put aside the aerospace project itself, this project is worth a try."

After a pause, he reached for his pen and unhurriedly annotated the meeting papers.

"Approve the project."

After thinking for a while, as if he didn't feel strong enough, he added another line to it.

"The relevant departments are fully cooperative."

Looking at these two lines, the old man nodded with satisfaction.

But at this moment, he suddenly remembered something, so he spoke.

"By the way, consult Professor Xia Lu, if he himself has no opinions, let's find a place to put this paper out."

As he spoke, he smiled and continued, "Now that a lot of smoke bombs have been released, we have to let people see it, so we have to make some moves." ”

……

Jinling University.

Lecture hall No. 1.

After the bell rang for the end of class, Lu Zhou closed the book in his hand and turned around and left the classroom.

Since the beginning of his number theory class, it has been almost full. Not only many undergraduates who have never enrolled in this course at all, but also some masters, doctors, and even other professors from the School of Mathematics occasionally come to listen to the lectures.

Personally, Lu Zhou still likes to exchange questions with students.

Thinking about simple questions once in a while is a unique way for him to relax.

Usually, after class, if he is not busy, he will leave 20 minutes to half an hour to answer the students' extracurricular questions.

Unfortunately, there is still a meeting on the miniaturization of controlled fusion projects in a moment, and I am afraid that there is no time for this today.

Walking on the road to the experimental building of the Academy of Mathematics, Lu Zhou planned to put the textbooks and lesson plans in the office before returning to the Institute for Advanced Study, and instructed a few of his students by the way.

However, at this moment, the mobile phone in his pocket suddenly rang.

Lu Zhou took out his mobile phone and looked at it, and found that it was Yang Xu calling, so he pressed the connected button, put the mobile phone to his ear and said.

"Hello?"

Yang Xu: "An old man who claims to be an academician of the Institute of Engineering Physics of the Chinese Academy of Sciences Yu Jiannan came to visit you...... Do you know? ”

Arrived so soon?

Hearing that Academician Yu had arrived, Lu Zhou's expression was a little surprised, the meeting only started at five o'clock, originally he thought that the few experts he invited would have to arrive after half past four in the afternoon, but he didn't expect this old gentleman to come so early.

It seems that the experimental building of this academy can't go there.

"I invited him here, take him to the C1 meeting room of the Institute of Physics."

Yang Xu: "Okay. ”

After hanging up the phone, Lu Zhou opened the address book and dialed the phone to Wang Peng.

"Where are you now?"

Wang Peng: "At the school gate." Need a car? ”

Lu Zhou: "Well, come to the lecture hall to pick me up." ”
