Xu Chuan didn't know what happened on Fuxing Road.
However, for him, whether Lao Aerospace cooperates or not does not have a big impact.
Just like the development of the field of controllable nuclear fusion, Chen Mingji's existence has not affected his research and development.
The development of science and technology is the eternal pursuit of mankind.
From the past to the present, humans have always been exploring and discovering new technological ideas to improve productivity and living standards.
Whether it is energy, materials, information or other fields, any cutting-edge technology is being developed and applied.
These technologies are leading future developments and will bring profound changes, as well as new economic, social and cultural challenges.
Just like the steam engine was crushed by the internal combustion engine and then disappeared in the process of history, this is the general trend and no one can resist it.
Of course, it would be great if the old aerospace group could form mutual cooperation and support with him.
Electric propulsion systems do have great advantages in the aerospace field, but they are not without their shortcomings.
Although the thrust of 500KN is already very large in the field of electric propulsion, and considering that the entry method and wiring of electric propulsion are different from traditional fossil fuel launch vehicles, it can send up to about fifty to sixty tons of items into the near earth.
In orbit, this is almost its limit.
For traditional fossil fuel rockets, this number is only one-tenth of that.
For example, SpaceX's starship can carry items weighing 550 tons into low-Earth orbit. Even the domestic Long March 9 can carry hundreds of tons of cargo to space.
When it comes to transporting large-mass cargo, traditional fossil fuel rockets have their own unique advantages.
In fact, in Xu Chuan's consideration, fossil fuel rockets also play an important role in this manned spaceflight and moon landing project.
He had previously communicated with scientific researchers and general managers of the Aerospace Science and Industry Corporation, including cooperation and poaching in the field of satellite acquisition technology, partly to prepare for this aspect.
The space shuttle carries people to space, and the fossil fuel launch vehicle transports large-mass cargo into orbit. Then the two dock in low-Earth orbit to complete the transfer of materials, and then the space shuttle goes to the moon to complete the moon landing and subsequent projects.
This method can maximize the combination of the advantages of the new space shuttle and the traditional chemical fuel launch vehicle.
The former can carry far more than fifty tons of materials, but the thrust is not enough to send more materials from the ground into low-Earth orbit, breaking away from the Earth's gravity constraints.
But once it leaves the earth's gravity field and enters low-Earth orbit, if the material transfer is completed in space, the space shuttle can carry hundreds or even thousands of tons of materials to the moon.
This is something that traditional chemical fuel launch vehicles cannot do.
Combining the advantages of the two can not only send more materials to the sky and the moon, but also save more money.
After all, propelling hundreds of tons of materials in space to the moon and carrying hundreds of tons of materials into space are two completely different concepts for the space shuttle.
The former can be said to be a piece of cake, while the latter requires several or even ten launches.
.......
After returning to Jinling from the capital, Xu Chuan's daily work fell on the construction of the space shuttle.
In early November, after almost a year, the miniaturized controllable nuclear fusion reactor modified through the Helix-7X data was finally completed in the core laboratory of the Institute of Energy Research.
Compared with the Huaxing fusion device, which is more than ten meters in diameter, this newly assembled small fusion reactor, or compact fusion reactor, is only three meters in diameter and less than two meters in height.
A reactor of this size looks extremely mini when placed in a laboratory.
"It's incredible that the fusion reactor can be so small. How did you do it?"
In the core laboratory, Yuan Yingcai, who came specially from the Aerospace Science and Industry Corporation to discuss cooperation, stood in the empty laboratory and looked at the small fusion reactor in front of him, which was not much taller than himself. His face was full of shock and surprise.
Although he had guessed that there would be a breakthrough in small-scale controllable nuclear fusion technology before he came, he was still shocked when such a small-scale fusion stack was placed in front of him.
Xu Chuan smiled and explained calmly: "It's not too difficult. The two items of permanent magnet stellarator and superconducting material with high critical magnetic field are the basis. If these two problems are solved, the volume of the fusion reactor must be completed."
Miniaturization is not that difficult.”
Hearing this, Yuan Yingcai recovered from the shock, and the corners of his mouth moved unnaturally.
It's not that difficult...
This is so pretentious...ahem...I really look down on miniaturized and controllable nuclear fusion technology, as if it can be solved easily.
But soon, he was keenly aware of the key point in this sentence, and quickly asked: "Permanent magnet stellarator? Stellarizer? What you are pursuing in miniaturized controllable nuclear fusion technology is stellarator.
The route is not the Tokamak route?”
In fact, it is not only Xinghai Research Institute that is studying the miniaturization of controllable nuclear fusion technology, but the Aerospace Science and Industry also has related projects.
But for now, they are still following the route of miniaturizing the tokamak device.
After all, the composite tokamak device has successfully achieved ignition. When it comes to making the size smaller, we naturally hope to make it larger based on the technology that has been realized.
However, from the establishment of the project to the present, Aerospace Science and Industry has not produced any effective results.
One year is not enough for their expert professors to fully understand the controllable nuclear fusion technology, let alone complete miniaturization on this basis.
What made him even more unexpected was that the miniaturization route taken by the Xinghai Research Institute was not tokamak, but another magnetic confinement path, the stellarator.
I have never heard of this news before.
This chapter is not finished yet, please click on the next page to continue reading the exciting content! And what new technology is the permanent magnet stellarator?
For a while, Yuan Yingcai had too many doubts and questions.
Xu Chuan smiled and nodded, saying: "That's right, this small reactor follows the path of a stellarator rather than a tokamak device."
"Because when the tokamak device is running, it is difficult to solve problems such as tearing of the plasma magnetic surface of the high-temperature plasma in the chamber, distortion, and plasma magnetic islands."
Yuan Yingcai frowned and asked quickly: "But hasn't the Dawn Fusion Device already solved this problem?"
Xu Chuan shook his head and said with a smile: "No, the Dawn Fusion Reactor is only forced down by expanding its volume, enhancing the critical magnetic field, and changing the structure of the outer magnetic field of the fusion reactor."
"This issue has not been fully resolved."
"As the size of the fusion reactor becomes smaller, this type of problem will become more and more serious. On the tokamak device, when the size is as small as about five meters * five meters * five meters, high-temperature plasma-related conflicts and tearing will occur.
The split is irreconcilable."
"So we chose to change a route that does not have problems such as plasma magnetic surface tearing, distortion, magnetic islands, etc., and the stellarator has its own advantages in this regard..."
Xu Chuan briefly explained the miniaturized fusion technology, and then said: "Just in time, the relevant inspections have been completed. Next, we are going to conduct an ignition experiment on this small reactor. Mr. Yuan, do you want to come over and take a look?"
Hearing this, Yuan Yingcai nodded vigorously and said: "Of course, if it is convenient."
Xu Chuan smiled and said: "It's nothing inconvenient, come with me."
With that said, he walked towards the main control room of the core laboratory.
Here, many scientific researchers and staff are busy in an nervous and orderly manner.
"How is the situation? When can the ignition be started?" Xu Chuan asked Liang Qu in the control room.
Although he proposed the route of the miniaturized fusion reactor and solved some of the core problems, he did not have much involvement in the overall design, manufacturing, assembly and other processes. They were all controlled by Liang Qu.
Seeing Xu Chuan, Liang Qu said hello and replied: "The preparation work has been completed. The final inspection is now being carried out. In about half an hour, the test will be completed and the ignition experiment will begin."
Xu Chuan nodded and took Yuan Yingcai to the other side to wait.
Half an hour was not long. Under the auspices of Liang Qu, the first ignition experiment of the miniaturized fusion reactor began.
Despite the experience of Huaxing fusion device, the test experiments of small reactors still started from the hydrogen and helium three simulation experiments.
Compared with the fusion of deuterium and tritium raw materials, although the hydrogen-helium three simulation operation cannot produce a complete fusion reaction, it has more advantages in increasing the temperature and controlling the plasma turbulence.
Of course, the more critical thing is that it can test the overall condition of the fusion reactor without causing widespread damage to the fusion reactor.
After all, if deuterium and tritium are added directly, without proper control, the energy generated by fusion will definitely cause huge impact damage to the reactor and chamber.
Even considering the amount of raw materials used for fusion, the high temperature and plasma created instantly cannot be underestimated.
There is nothing related to nuclear testing that is not dangerous.
.....
[Steady-state magnetic field strength reaches 78.55 Tesla, goal achieved!]
[The fine-tuning magnetic field has been corrected according to the instructions, and the magnetic field in the reaction chamber has reached the target plan!]
【.......】
【Helium III raw material has been injected!】
[The ICRF heating antenna has been started up. The current temperature has reached 47 million degrees Celsius and is expected to reach 80 million degrees Celsius in ten minutes!]
【.......】
In the main control room, Xu Chuan sat quietly on a chair, watching Liang Qu's command of the small reactor simulation experiment, and listening to the various work reports fed back to his ears.
For today's energy research institute, completing a hydrogen-helium three simulation experiment is not something worth paying attention to.
If it weren't for the fact that this was the first time the small reactor had been ignited after assembly and the stakes were so high, Xu Chuan wouldn't even bother to come over and take a look.
After all, he has done relevant experiments countless times. Even for other people at the Energy Research Institute, completing nuclear fusion experiments is not an unusual task.
Everyone is at their posts, steadily and orderly promoting the operation of the small reactor.
Until, in the control room, an exciting report was delivered
【Deuterium-tritium fusion reaction detected!】
A brief report excited everyone in the control room.
The deuterium-tritium ignition experiment of a small reactor was successful!
Looking at the dancing curves and data on the main control screen, Xu Chuan also had a faint smile on his face.
Just as he expected, the small reactor successfully completed the ignition after undergoing countless experimental simulations and data adjustments of the Huaxing Fusion Device.
Although some parameters and experiments still need to be adjusted in the future, they have already passed the most core and critical step!
........
In the control room, Yuan Yingcai, who was invited to participate in the ignition experiment, felt a little dazed after watching the entire simulation experiment and ignition process, feeling the cheers in the control room.
This...is this a success?
Didn’t it say that this was the first ignition experiment of a small reactor?
Is this done?
What's the situation? Is it a little too relaxed and a little too fast?
Didn't he feel any atmosphere of tension and expectation throughout the whole process?
Noticing the movement here, Xu Chuan smiled and said, "How do you feel?"
Hearing this, Yuan Yingcai came back to his senses, swallowed and couldn't help asking: "Why don't I feel anything? It doesn't look like the small reactor test was successful at all."
After a pause, he then added: "An important experiment like a small reactor has been successful. Where are the cheers? Where is the joy? Where is the celebration? Are you a little too calm?"
This chapter is not over yet, please click on the next page to continue reading! Hearing this, Xu Chuan smiled lightly and said: "For Xinghai Research Institute, the technology of small reactors is already quite mature."
"Early before this experiment, Huaxing Fusion Device had conducted countless ignition and operation experiments through simulations. With this experience and data, the ignition of small reactors is not difficult for us."
"As for celebrating with joy and joy, of course there will be, but not now."
"When the celebration banquet comes, they will naturally cheer and celebrate."
"As for now, there is still a lot of work waiting for them."
As he spoke, he pursed his lips, pointed to the researchers who were still working at their posts, and continued: "This time's experiment, in addition to ignition to complete deuterium and tritium fusion, also requires running time and plasma temperature limits.
Test, device flip stability test and other experiments.”
"Because this small reactor is used on the space shuttle, we need to conduct the most detailed experiments and tests under various conditions it may encounter during operation, and obtain relevant data to judge whether it is truly successful.
Already."
Standing in the main control room, the expression on Yuan Yingcai's face was not only shocked, but also a bit complicated, and even a little suspicious.
In fact, even now, he still can't believe that the miniaturized fusion reactor has successfully ignited.
Not only are there doubts about whether the technology itself can be done, but also doubts about the calm behavior of these people in the main control room after the experiment was successful.
Everyone, including Xu Chuan, was so indifferent to the success of the ignition that he had to doubt whether the ignition was really successful this time, rather than fabricating experiments and data to deceive him.
But the facts displayed in front of him at this moment, including the data fed back to the control room, the high-temperature plasma running in the small reactor chamber, and the electrical energy output outward, at this moment, all those things in his mind
