Great Country Academician

Hearing Gao Hongming's question, Xu Chuan knew what the higher-ups wanted to do.

Install a controllable nuclear fusion reactor on an aircraft carrier, 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 that of a space shuttle or a space station. In theory, it should be enough to accommodate a fusion reactor in terms of length, width and height.

The only problem is that today's fusion reactors and associated equipment are too bloated.

It’s okay to put it on the ground, but on the aircraft carrier, even if he redesigns it and tries his best to reduce the size of the fusion reactor, I’m afraid it will take up at least one-fifth or even more than one-third of the space of an aircraft carrier.

This is the limitation of the fusion reactor itself, otherwise he would not have thought that miniaturized nuclear fusion would need to start from other fields.

For miniaturized nuclear fusion devices, it is not enough to simply make the reactor smaller.

According to the self-sustaining Lawson's criterion of fusion reaction and ignition conditions, the plasma number density, temperature, and confinement time must satisfy a certain relationship.

And 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 too small means that a huge temperature and density gradient is required, which will cause many instabilities.

Of course, even if it occupies more than one-fifth of the space of the aircraft carrier, a fusion reactor can bring great changes to the aircraft carrier.

The first is power and battery life.

Under the powerful energy supply of controllable nuclear fusion, the endurance of the aircraft carrier can be said to be almost unlimited, and its power system can be strengthened to the extreme.

As long as the supporting engine can provide powerful power, it seems impossible for the aircraft carrier to soar to the speedboat level with the support of the fusion reactor?

This situation is quite touching when you think about it.

An aircraft carrier with a capacity of more than 100,000 tons can sail so fast that it can take off, so don’t worry about battery life, the picture is a bit too beautiful.

"Interesting, who came up with this idea?"

Xu Chuan thought about it, and asked curiously.

Although after the emergence of a certain advanced technology, the first field of application will definitely be the military. But he didn't seem to have thought much about packaging and installing controllable nuclear fusion on the aircraft carrier.

Of course, he was thinking of more advanced things, such as miniaturizing the fusion reactor and stuffing it on the space shuttle or spacecraft.

However, the miniaturization of controllable nuclear fusion and aerospace engines are two major problems.

If you want to build a space carrier similar to an aircraft carrier, you can't find an engine that can provide such a large thrust now.

Perhaps it is possible in the vacuum of the universe. After all, there is almost no resistance, and you can fly forward with just a little thrust.

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 higher authorities want to put the nuclear fusion pile on the aircraft carrier to provide power for it, which seems good to him, after all, it can collect some data and make some preparations for the subsequent fusion pile to go to the sky.

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, in fact, a long time ago, countries have plans, but it has always been something on paper."

"Now that we have done it, we will naturally think about putting the fusion stack on the aircraft carrier to provide power and energy for the aircraft carrier."

"It just so happens that our No. 003 aircraft carrier is still being remodeled, so the higher-ups have thought of this. I have asked relevant experts and professors from the Academy of Sciences to learn about it, but the higher-ups still want to ask for your opinion."

Xu Chuan nodded, thought for a while, and said, "In theory, this should be feasible."

"The fusion power of the controllable fusion reactor under the magnetic confinement route is proportional to the fourth power of the magnetic field strength, and proportional to the first power of the cavity volume."

"Therefore, under the same fusion output power conditions, doubling the magnetic field strength can greatly reduce the volume of the fusion reactor."

"The Lixiao Demonstration Reactor is a medium-to-large demonstration reactor based on the power supply for Jiangsu Province. Its external field coil uses a copper-carbon-silver composite superconducting material with high magnetic field strength. It is possible to shrink it in 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 the external field coil should stably maintain secondary confinement and fusion capabilities. And the output power of five million kilowatts, the smallest diameter also needs to be stable at 8.4 meters in diameter."

"If other supporting equipment is included, according to preliminary calculations, its footprint needs to be at least 20 meters long, 15 meters wide, and 10 meters high, regardless of the generator set."

"I don't know if the current aircraft carrier can provide such a large area for the fusion reactor, but if it can be done, it is theoretically feasible to cram the fusion reactor into the aircraft carrier."

After a pause, Xu Chuan continued: "If fusion can be stacked on the aircraft carrier, then there is no problem in using the electromagnetic acceleration track to provide energy for carrier-based aircraft, electromagnetic weapons and other equipment."

"If I remember correctly, the nuclear fission reactors of the Nimitz and Ford-class aircraft carriers in the United States seem to provide less than 300,000 kilowatts of power."

"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 calculations in his mind for the fusion reactor.

On the opposite side, Gao Hongming took out a small notebook at some point, and was happily recording the core points.

Although he didn't quite understand what Xu Chuan said, just the output power of 5 million kilowatts compared to 300,000 kilowatts was enough to make him excited.

Sure enough, compared with nuclear fusion technology, nuclear fission is a slag.

If you build a fusion reactor aircraft carrier fleet, coupled with corresponding electromagnetic weapons, the world is so big, where can't you go?

After jovially jotting down the knowledge points of the big guy in front of him, Gao Hongming closed the notebook and said with a smile, "Thank you, Academician Xu, for your valuable opinions. I will pass them all back."

Xu Chuan smiled and said, "It is also my dream to see the strength of the motherland."

Gao Hongming didn't stay here for long in Jinling. He met Xu Chuan, chatted about some things, and returned to the capital with some information.

But the newcomer, Wen Yuanhang, is now based in Jinling.

After taking him to get acquainted with the environment and core personnel, Xu Chuan left the reorganization and transformation of Qixia Controllable Nuclear Fusion Research Institute to this 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 Chuanhai Materials Research Institute.

In two years, the Chuanhai Materials Research Institute has expanded into a medium-to-large research institution with sufficient funds.

If Xu Chuan hadn't intentionally controlled its scale, its expansion would have been faster.

"About South Korea's KL-66 room temperature superconducting material, what's the result of the model checking?"

In the research institute, Xu Chuan found his elder brother Fan Pengyue and asked.

Yesterday he sent the news of the paper he saw on the arxiv preprint website to the Chuanhai Materials Research Institute, and arranged for a replica experiment.

Although it takes about three days to reproduce the experiment, Chuanhai Materials Research Institute also has a mathematical model for material calculation that has been developed for two years.

Through this mathematical model, in the case of synthesis steps and experimental data, it is no problem to use a computer to do a simulation test first.

"The first round of simulated synthetic tests were 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 has not simulated the complete superconducting properties after checking the numerical control model."

Hearing this, Xu Chuan was a little curious: "What is the situation that the complete superconducting performance has not been 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, it is found that some of its superconducting phenomena sometimes do not exist."

"For example, complete diamagnetism. During multiple tests, there will occasionally be one or two results that cannot be verified for diamagnetism."

"Or zero resistance, this is even more weird. In the material tests of many times of simulated synthesis, 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."

PS: There is another chapter in the evening, asking for a monthly pass.
