After hearing Gao Hongming's question, Xu Chuan knew what his superiors wanted to do.
Installing a controllable nuclear fusion reactor on an aircraft carrier, a nuclear fusion aircraft carrier?
It has to be said that this idea is relatively easier than installing a fusion reactor on the space shuttle.
The size of an aircraft carrier is much larger than a space shuttle or a space station. Regardless of length, width and height, theoretically speaking, it should be enough to house a fusion reactor.
The only problem is that today's fusion reactors and supporting equipment are too bloated.
It's okay to put it on the ground, but put it on an aircraft carrier, even if it redesigns it and tries its best to reduce the size of the fusion reactor, it will probably occupy at least one-fifth or even more than one-third of the space of an aircraft carrier.
This is a limitation of the fusion reactor itself, otherwise he would not want to start miniaturizing nuclear fusion and would need to start from other fields.
To miniaturize the nuclear fusion device, it is not enough to just make the reactor smaller.
According to the Lawson criterion of self-sustained fusion reaction and ignition conditions, the plasma number density, temperature, and confinement time must satisfy a certain relationship.
This relationship requires that the plasma density and temperature cannot be too low, which actually requires that the tokamak or other magnetic confinement devices cannot be too small.
Because being too small means requiring extremely large temperature and density gradients, which will cause a lot of instability.
Of course, even if it occupies more than one-fifth of the space of an aircraft carrier, a fusion reactor can bring huge changes to the aircraft carrier.
The first is power and battery life.
With the powerful energy supply of controllable nuclear fusion, the aircraft carrier's endurance can be said to be nearly unlimited, and its power system can be enhanced to the extreme.
As long as the supporting engine can provide powerful power, with the support of the fusion reactor, it does not seem impossible that the speed of the aircraft carrier will soar to the level of a speedboat?
This situation is quite touching when I think about it.
An aircraft carrier weighing more than 100,000 tons can sail so fast that it can fly. Don’t worry about battery life. The picture is a bit too beautiful.
"Interesting, who came up with this idea?"
Xu Chuan thought for a moment and asked curiously.
Although after the emergence of a certain advanced technology, the first field of application will definitely be the military. But it seems that he has not really thought much about packaging and installing controllable nuclear fusion on an aircraft carrier.
Of course, he was thinking of something more advanced, such as miniaturizing a fusion reactor and stuffing it into a space shuttle or spacecraft.
However, miniaturization of controllable nuclear fusion and aerospace engines are two major problems.
If we want to build a space carrier similar to an aircraft carrier, we simply cannot find an engine that can provide such a large thrust.
Maybe it can be done in the vacuum of space. After all, there is almost no resistance, and you can fly forward with just a little push.
But if it is placed in the atmosphere, it will not be able to fly at all due to the influence of gravity.
Now the superiors want to put the nuclear fusion stack on the aircraft carrier to provide power for it. This seems to be a good idea for him. After all, he can collect some data and make preparations for the subsequent launch of the fusion reactor into space.
Gao Hongming coughed lightly and said, "I don't know who came up with this idea. After all, before the advent of controllable nuclear fusion, fission reactor-powered aircraft carriers already existed."
"As for the fusion reactor aircraft carrier, countries have actually had plans a long time ago, but they have always been on paper."
"Now that we have done it, we will naturally think about putting fusion stacks on aircraft carriers to provide power and energy for the aircraft carriers."
"It just so happens that our aircraft carrier No. 003 is still being renovated, so the above thought of something in this regard. I have consulted with relevant experts and professors from the Academy of Sciences, but the senior management still wants to ask for your opinion."
Xu Chuan nodded, thought for a moment, and said, "Theoretically, this should be feasible."
"The fusion power of a controllable fusion reactor under the magnetic confinement route is proportional to the fourth power of the magnetic field intensity and proportional to the first power of the cavity volume."
"Therefore, under the same fusion output power conditions, exponentially increasing the magnetic field intensity can significantly reduce the size of the fusion reactor."
"The Daybreak Demonstration Reactor is a medium-to-large demonstration reactor built to provide power to Sujiang Province. Its external field coil uses copper-carbon-silver composite superconducting material with high magnetic field strength. It can be made smaller within the limit of magnetic confinement.
Arrived."
"Of course, this reduction will not be too small. According to my previous calculations, theoretically speaking, a hybrid fusion reactor made of copper-carbon-silver composite superconducting material as an external field coil must stably maintain sub-confinement capabilities and fusion capabilities.
And if the output power is five million kilowatts, the minimum diameter needs to be stable at 8.4 meters."
"If you include other supporting equipment, according to preliminary calculations, the floor space, apart from the generator set, needs to be at least 20 meters long, 15 meters wide, and about 10 meters high."
"I don't know if the current aircraft carrier can provide such a large area for the use of fusion reactors, but if it can be done, it is theoretically feasible to stuff the fusion reactor into the aircraft carrier."
After a pause, Xu Chuan continued: "If fusion can be stacked on an aircraft carrier, then there will be no problem in using electromagnetic acceleration orbits to provide energy for carrier-based aircraft, electromagnetic weapons and other equipment."
"If I remember correctly, the power provided by the nuclear fission reactors of the US Nimitz and Ford-class aircraft carriers seems to be less than 300,000 kilowatts."
"Of course, the space occupied by the fission reactors on the Nimitz and Ford-class aircraft carriers should not be as large as the fusion reactors."
Xu Chuan simply stated some of his calculations regarding the fusion reactor.
Opposite me, Gao Hongming took out a small notebook out of nowhere and was happily recording the key points.
Although he didn't quite understand what Xu Chuan said, just the output power of 5 million kilowatts compared to the output power of 300,000 kilowatts was enough to excite him.
Sure enough, compared to nuclear fusion technology, nuclear fission is dregs.
This chapter is not finished yet, please click on the next page to continue reading the exciting content! If we build a fusion reactor aircraft carrier fleet and equip it with corresponding electromagnetic weapons, in this vast world, where can we not go?
After happily jotting down the knowledge points mentioned by the big man in front of him, Gao Hongming closed his notebook and said with a smile: "Thank you very much, Academician Xu, for your valuable opinions. I will pass them back in full."
Xu Chuan smiled and said: "It is also my dream to see the motherland become strong."
...
Gao Hongming didn't stay in Jinling for long. He met with Xu Chuan and chatted for a while before returning to the capital with some information.
But the newly arrived Wen Yuanhang is based here in Jinling.
After taking him to familiarize himself with the environment and core personnel, Xu Chuan left the reorganization and transformation of the Qixia Controlled Nuclear Fusion Research Institute to Manager Wen.
He is not good at administrative work and has no time to spend on it.
After arranging these things, Xu Chuan came to Sichuan-Hai Materials Research Institute.
In two years, with sufficient funding, the Sichuan-Hai Materials Research Institute has expanded into a medium-to-large research institution.
If Xu Chuan hadn't deliberately controlled its scale, it would have expanded even faster.
"Regarding the KL-66 room temperature superconducting material in South Korea, what are the results of the model verification?"
In the research institute, Xu Chuan found his senior brother Fan Pengyue and asked.
Yesterday, he sent the news about the paper he saw on the arxiv preprint website to the Sichuan Hai Materials Research Institute and arranged a replica experiment.
Although it takes about three days to replicate the experiment, the Sichuan-Hai Materials Research Institute also has a mathematical model for materials calculation that took two years to develop.
Through this mathematical model, when there are both synthesis steps and experimental data, there is no problem in using a computer to do a simulation test first.
"The first round of simulation synthesis testing was done, and the results were not very good."
Fan Pengyue shook his head and continued: "I have sent the relevant data to your email. Judging from the simulation test results of the model, there is no problem in synthesizing this KL-66 material according to the method provided in the paper."
"However, the synthesized KL-66 material, after verification by the CNC model, did not simulate the complete superconducting performance."
Hearing this, Xu Chuan was a little curious: "What happens if the complete superconducting performance is not simulated?"
Fan Pengyue: "It may be that the functions of the temporarily added modules are not very perfect. When doing simulation tests on this KL-66 material, we found that some of its superconducting phenomena are sometimes absent."
"For example, if it is completely diamagnetic, during multiple tests, there will occasionally be one or two results that cannot verify the diamagnetism."
"Or zero resistance, which is even weirder. In many simulated synthetic material tests, it has never appeared at room temperature, but if the temperature is lowered to about minus 160 degrees Celsius, it can appear."
"Under this strange simulation situation, it is difficult to judge whether this KL-66 room temperature superconducting material is really superconducting."
