Walking on the road leading to the laboratory building of the Institute of Mathematics, Lu Zhou planned to put the textbooks and lesson plans in the office before returning to the Institute for Advanced Study, and give some guidance to some of his students.
"You are right. Regardless of whether it can be technically realized or not, even if we put aside the aerospace engineering itself, this project is worth a try."
"Ahem, I seem to have missed a few things just now. Whether the thrust can be greater depends on the power of electric propulsion. It is really impossible to do it with traditional nuclear batteries. Power and electricity are both shortcomings, but fusion batteries are really It’s hard to say, it’s hard to say…”
When Mr. Wu said this, the atmosphere in the conference room was a little awkward.
"Where are you now?"
After thinking for a while, he seemed to feel that the strength was not enough, so he added another line above.
Since his number theory class started, the class has been almost full. Not only many undergraduates who have never signed up for this course come to attend the class, but some masters, doctoral students, and even other professors from the School of Mathematics also occasionally come to attend the class.
Otherwise his reaction would not have been so strong.
As far as Lu Zhou is concerned, he still likes to communicate with students.
The silence was eerie.
Mr. Wu looked slightly embarrassed and reached out to pick up the paper again.
"Hello?"
"Approval of the project."
Lecture Room No. 1.
"If this can send satellites from the surface of the earth to the sky, then even qigong can launch satellites!"
"...It was written by Chief Designer Lu."
"I invited him here. Take him to the C1 conference room of the Institute of Physics."
"Can I give you my perspective?"
Yang Xu: "Okay."
Although I know this old scientist's temper is like this.
After hearing these words, the expressions of many people present became serious.
"It's just nonsense!"
The conference room was quiet for a while.
As he said that, he smiled and continued, "A lot of smoke bombs have been set off now. At least we have to let people see it. We have to do something."
After a while, he made a sudden expression, used the controllable fusion miniaturization that he had not commented on before as a step, buried his head and muttered.
The man paused and continued: "I don't know much about aerospace matters, so I won't comment here. But I think that even leaving aside things like Hall thrusters and electric propulsion rockets, this controllable fusion miniaturization Research is also quite necessary.”
It was because they were worried about this happening that they deliberately concealed the name of the author of the paper.
But this thing about qigong...
Lu Zhou took out his phone and took a look at it. He found that it was Yang Xu, so he pressed the connect button, put the phone to his ear and said.
After pondering for a while, the old man nodded.
"About the application prospects and technical feasibility demonstration of controllable fusion miniaturization technology in the aerospace field"
Old man: "Please speak."
At this time, a man with an epaulette on his shoulder who had not spoken before spoke seriously.
There are 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 aerospace field.
Not to mention such an advanced concept...
After hearing this, Ren Changming didn't know what to do.
Jinling University.
Placed at the top of the conference materials is a paper with an eye-catching title.
…
The paper gives a certain professional description of the application of miniaturized controllable fusion reactors in the aerospace field and the associated Hall thrusters, and uses rigorous calculations to demonstrate the possibility of its technical realization.
It seems that we can't go to the laboratory building of this math institute.
Xu Yuanming: "..."
As for the miniaturization of controlled fusion, he didn't know much and didn't want to comment.
However, it is not easy for such academic experts to find people to review their projects.
The earliest nuclear fission battery was as big as a small house. When it was first built, no one expected it to be used in spacecraft.
However, in just a few years, around the 1970s, the problem of miniaturization was properly solved. And now, the smallest one can even be as big as a fifty-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).
Usually after class, if he is not busy, he will leave twenty minutes to half an hour to answer extracurricular questions raised by students.
"Relevant departments are fully cooperating."
Lu Zhou: "Well, pick me up at the lecture theater."
But no one expected that Mr. Wu, who would not even let the former chief designer of the lunar exploration project become an academician in arguments, would not be able to identify the author after hearing that the author of the paper was Professor Lu. own position.
"By the way, let's consult Professor Lu. If he doesn't have any objections, let's find a place to publish this paper."
Go to Beijing, in a certain conference room.
Each person holds a copy of the inch-thick meeting materials and places them on the conference table in front of him.
Can you forget to mention it
"I think the person who wrote this paper is completely out of his mind!"
But judging from his previous reaction, this thing should be really difficult to do.
After a pause, he reached out and picked up the pen, and made notes on the meeting documents unhurriedly.
Any project must be reviewed by a panel of experts, even winners of the Nobel Prize and the Lingyun Medal are no exception.
Wang Peng: "At the school gate. Do you need a car?"
"You have been away from the front line of scientific research for too long. I won't argue with you about this." Academician Wu waved his hand and tapped the paper with his index finger. "Who wrote this paper? Come to him, I will talk to you. He reasoned in person!"
Unfortunately, there will be a meeting on the controllable fusion miniaturization project to be held soon, and I am afraid there is no time for it today.
Yang Xu: "An old man who claims to be Academician Yu Jiannan of the Institute of Engineering Physics of the Chinese Academy of Sciences came to visit you... Do you know him?"
Academician Wu shook his head and said: "It basically can't be solved!"
But at this moment, he suddenly remembered something, so he spoke.
"...I'll think about it some more."
Putting down the paper in his hand, Academician Wu shook his head and criticized unceremoniously, "Looking at the specific impulse alone, electric thrust is indeed much stronger than chemical thrusters, but thrust is a flaw that cannot be solved!"
The class boundaries in domestic academia are very clear. It is taboo to publicly comment on people with higher connections, status, and academic reputation than oneself.
Hearing that this old subordinate dismissed this paper as worthless, Ren Changming looked a little embarrassed, so he tried to smooth things over.
Looking at these two lines of words, the old man nodded with satisfaction.
No one can say what future technology will be like.
“According to the description in this paper, if the controllable fusion miniaturization technology can really be realized, its application areas may not only be installed on spacecrafts, but also maybe installed on our submarines or even aircraft carriers. .”
"The idea proposed in this paper is indeed a bit optimistic. I admit that it is difficult to achieve the level mentioned in this paper, but I think this difficulty is not completely unsolvable, right?"
After exchanging glances with the leader of the Ministry of Science and Technology and the old man sitting next to him, Xu Yuanming coughed lightly and spoke out after receiving the instruction.
However, at this moment, the cell phone in his pocket suddenly rang.
However, demonstrating the feasibility of technologies that have not yet been realized is inherently subjective.
"Not to mention anything else, the VX-200SS ion engine that our Fourth Aerospace Institute completed trial operation last year can reach 200KW in power, and the total thrust is only 5N! Even if it can be increased a hundred times, a thousand Times, can you use this kind of thrust to push a spacecraft into low-Earth orbit? It would be difficult to send an egg up there!"
Lu Zhou looked a little surprised when he heard that Academician Yu had arrived. The meeting only started at five o'clock. He originally thought that the experts he invited would not arrive until after 4:30 p.m., but he did not expect that this meeting in Laozhou would arrive after 4:30 p.m. Sir, you came so early.
Arriving so soon
After hanging up the phone, Lu Zhou opened his address book and dialed Wang Peng.
Everyone in the conference room: "..."
After the get out of class bell rang, Lu Zhou closed the book in his hand, turned around and left the classroom.
The leader of the Ministry of Science and Technology had a confused expression on his face, but the old man sitting next to him didn't pay attention. He just said thoughtfully: "Can't it be solved?"
Occasionally thinking about some simple questions is a unique way of relaxing for him.
However, it has only been a little over three months since the demonstration reactor in Haizhou was successful, and now they are planning to install the reactor on a spacecraft, which is probably the kind of bragging that goes without saying anything.
