Deep Space Fleet

Zhang Yuan nodded, expressing his understanding.

Even a lazy guy like Li Zhendong has become hasty during this period of time, wanting to make some achievements.

When I first boarded the spaceship, although there was the pain of parting, there was also a sense of anticipation and freshness for the future.

But now, this sense of anticipation is slowly passing, the pace of life in the spacecraft has become faster and faster, and the number of people chatting on the side of the road has obviously decreased.

Because everyone clearly knows that this is in the desolate and vast universe, and this mothership is everyone's everything.

This sense of security is seriously lacking.

Although the "Earth Age" is huge and warm and comfortable, it still cannot compare with the earth, a planet that has stood in the universe for 4.6 billion years.

A medium-sized meteorite, if it collides with it, can completely destroy the spacecraft without anyone surviving.

Humans, small and fragile creatures. An ordinary person, if he is exposed in the universe without a space suit, his life will not exceed 90 seconds, the air in the lungs will completely escape the body within a few seconds, and the residual oxygen in the blood can last for about 15 seconds.

After the next 15 seconds, the person will fall into a coma, and it is up to fate whether they can survive.

Just because everyone is aware of these common senses, with the distance from the home planet, a strong sense of uneasiness can't help but arise.

Even Zhang Yuan himself has such a sense of uneasiness. He often has convulsions in dreams, wakes up, finds that he just had a nightmare, and then falls asleep drowsily.

Therefore, Zhang Yuan's little entertainment gossip became a life-saving straw, and was talked about with great enthusiasm. Because people want to deliberately create a relaxed environment similar to the earth in the intense work to comfort their fearful subconscious mind.

Such subconscious changes are normal, and there are some psychologists in the spaceship who are responsible for this aspect of control. Large group events are often held within various communities, not only to increase group awareness, but also to treat cosmophobia in a small way.

But even so, dozens of patients with depression appeared in half a year.

"So, if you want to find a life partner, it's best to find a more beautiful girlfriend. Two people can complain to each other, and one person can only resist. Unless your psychological quality is particularly good..."

Here we go again, here we go again.

Zhang Yuan quickly turned his head away, pretending he didn't hear it.

"By the way, after the spacecraft turns successfully, the nuclear power engine will be shut down, and it will be turned on again half a year later. If there is any observation experiment, you only have one day today... Or, you can also visit the sideways engine. "

Zhang Yuan nodded, Senior Brother Zhao is indeed a very good instructor. Even when the experimental conditions are very poor, it is always possible to make very well-timed suggestions.

From this point of view, Academician Biding is more qualified. So far, except for the regular meeting at the beginning of each month, Zhang Yuan has not seen Ding Zhaodong a few times... Even if he did, he couldn't say a few words.

In the next few minutes, he walked unhurriedly to the lateral engine observation room, where there were bright display screens, and many staff members were focusing on the parameter changes.

From one of the display screens, it can be seen that long plasma flames are ejected from the flanks, causing the entire spacecraft to slowly rotate.

The angular speed of the spaceship's rotation is very low, and it takes more than 20 hours to complete a 180-degree rotation, so everyone basically didn't notice anything.

Looking at the second screen, it shows the plasma turbulence in the reaction furnace. Under the extremely high brightness, even after special treatment, it is still a bit dazzling.

This infrared spectrum is like a complex water vortex, and the transport of plasma across the magnetic field is mainly driven by low-frequency drift wave turbulence.

"Hi, Zhang Yuan!"

"Hi, hello." He greeted several colleagues, but no one paid any attention to him. Zhang Yuan started studying these screens on his own.

The high temperature generated by nuclear fusion will vaporize the sodium metal in the furnace wall, and the scorching sodium vapor can do work externally to generate electricity.

At the same time, the plasma will be ejected as a working fluid under the action of the magnetic field to provide kinetic energy for the spacecraft.

The principle is very simple to say, but this nuclear engine device is the crystallization of the highest wisdom of mankind. It's so complex that every single part, even the way it's welded, could write a thesis!

It is also the second generation nuclear fusion engine of mankind.

After fusion of a helium-3 nucleus and a deuterium nucleus, a helium-4, a proton and huge energy are produced. Since neutrons are not produced, it is cleaner and more stable than deuterium-tritium fusion, and the maintenance cost is also lower.

However, mining helium-3 on the moon is actually a big trick in aerospace engineering. Because the abundance of helium-3 in the lunar soil is too low, the cost of mining is too high. After calculation, you will find that using helium-3 fusion is not as cost-effective as using the first-generation deuterium-tritium fusion.

However, it is not useless to establish a space base on the moon, because the moon is the most suitable natural base for space industry production. Even if the helium-3 in it is ignored, the moon still has great development value.

It wasn't until the later Jupiter base was developed that the second-generation nuclear engineering helium-3 fusion was really popularized.

"What you see now is the flow image of plasma turbulence, how beautiful it is! The control software in it was designed by your father using the wavelet transform method thirty years ago, and it is also the best algorithm for human beings at present."

In the observation room, a brother named John Wilson spoke up.

"Really? The general method of wavelet transform..." Hearing his father's name, Zhang Yuan was very proud.

"But in essence, the problem of plasma turbulence has not been completely solved yet."

John Wilson is a high-tech talent who specializes in the study of plasma physics. He laments that human technology is too poor and naive all day long.

However, he is actually a very simple person.

"Isn't the restraint very good now? The current method is quite stable. Theoretically speaking, there will be no accidents for dozens or hundreds of years." Zhang Yuan was a little unconvinced when he heard John questioning his father's achievements.

"Yes, it's indeed very stable. But in your ancient Xia language, it's a miracle with great force, and it's really not wonderful to restrain these plasmas in a very rough way!"

John Wilson said very positively: "If only a 10 T magnetic field is used for confinement, I can guarantee that these high-temperature plasmas will still splash onto the furnace wall and stop the entire device from operating!"

The strength of the magnetic field used by humans is 100T, which is 10 times larger.

Coupled with the fact that supercomputers monitor these plasma turbulences all the time, and use super powerful computing power to maintain the balance of turbulence, it is no wonder that it is called a typical miracle of great efforts.
