Deep Space Planet Leader

Zhang Yuan nodded, which means you can understand.

Even lazy people like Li Zhendong have become hurried during this period, wanting to make some achievements.

When I went to spaceship at first, although I had the pain of parting, I also had a sense of anticipation and freshness for the future.

But now, this sense of expectation is slowly passing away, the pace of life in spaceship has become faster and faster, and there are obviously fewer people chatting on the roadside.

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

This sense of security is seriously inadequate.

Although "Earth Era" is huge and warm and comfortable, it still can't compare with Earth, a planet that has stood for 4.6 billion years in the universe.

A medium-sized meteorite, if it collides with it, can completely destroy the spaceship, and no one can survive.

Humans, small and fragile creatures. If an ordinary person is naked in the universe without a spacesuit, his life will not exceed 90 seconds, the air in the lungs will completely escape from the body within a few seconds, and the residual oxygen in the blood can last for about 15 seconds.

In the next 15 seconds, people will fall into a coma, and whether they can survive or not will be left to fate.

Because everyone knows these common sense, as the home planet moves away, involuntarily a strong sense of uneasiness arises.

Even Zhang Yuan himself has such a sense of uneasiness. He often convulsed in his dreams and woke up to find that he had just had a nightmare and fell into a drowsy sleep.

So Zhang Yuan's entertainment gossip turned into a life-saving straw, and he was talked about. Because people want to deliberately create a relaxed environment similar to Earth in their intense work to comfort their fearful subconscious.

Such subconscious changes are normal. There are some psychologists in spaceship who are specifically responsible for this aspect of control. Large-scale group activities are often held in various communities, not only to increase group awareness, but also to treat cosmophobia.

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

"So, to find a life partner, it is best to find a more beautiful girlfriend. Two people can also complain to each other, but one person can only resist. Unless your psychological quality Especially good..."

Here again, here again.

Zhang Yuan turned his head quickly, just as he didn't hear it.

"By the way, after the spaceship is successfully turned, the nuclear power engine will be turned off and will not be turned on again after half a year. If there is any observation experiment, you only have one day today... Or you can Go take a look at the lateral engine."

Zhang Yuan nodded, Senior Brother Zhao is indeed a very good instructor. Even in the case of very poor experimental conditions, it is always possible to make recommendations that fit the timing very well.

In this regard, he is more qualified than Academician Ding. Up to now, except for the regular meeting at the beginning of each month, Zhang Yuan has not seen Ding Zhaodong several times... Sentence.

In the next few minutes, he came to the side-facing engine observation room at a moderate pace, where there were bright display screens, and many workers were focusing on the parameter changes.

From one of the display screens, you can see that a long plasma flame spurts from the flanks, causing the entire spaceship to rotate slowly.

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

Looked towards the second screen again, it shows the plasma turbulence in the reactor. Under extremely high brightness, even if it has been specially processed, it is still a bit dazzling.

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

"Hi, Zhang Yuan!"

"Hi, hello." I greeted a few colleagues, and didn't care about him. Zhang Yuan each minding their own business studied these screens.

The high temperature produced by nuclear fusion will vaporize the sodium metal in the furnace wall. These hot sodium vapors can do external work and generate electricity.

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

The principle is simple to say, but this nuclear engine device is the crystallization of the highest human wisdom. It is so complicated that every component, even the welding method, can write a paper!

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

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

However, mining helium-3 on the moon is actually a big flicker in aviation engineering. Because the abundance of helium-3 in the lunar soil is too low, and the cost of mining is too huge, after calculating, you will find that using helium-3 fusion is not as cost-effective as using the first generation of 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 industrial production. Even if the helium-3 is ignored, the moon still has great development value.

It wasn't until the Jupiter base at the back was developed and the second-generation nuclear engineering helium-3 fusion was truly popularized.

"What you see now is the flow image of plasma turbulence, how beautiful! The control software in it was designed by your father 30 years ago using the general method of wavelet transform, and it is also the most popular Good algorithm."

In the observation room, a Senior Brother named John Wilson spoke.

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

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

John Wilson is a high-tech talent specializing in plasma physics, working day and night. They are all lamenting that human technology is too poor, too naive, and so on.

However, he is actually a very simple person.

"Isn’t the constraint very good now? The current method is quite stable. In theory, there will be no accidents for dozens or hundreds of years." Hearing John questioning his father’s results, Zhang Yuan was a little unconvinced.

"Yes, it is indeed very stable. But in your ancient Xia language, it is to vigorously create miracles and use a very rough way to restrain these plasmas. It is really not wonderful!"

John Wilson said with certainty: "If only 10 T magnetic fields are used for restraint, I can guarantee that these high-temperature plasmas will still splash on the furnace wall and stop the entire device!"

The magnetic field intensity used by humans is 100T, which is 10 times larger.

In addition, supercomputers constantly monitor these plasma turbulences, and use super computing power to maintain the balance of turbulence. It is no wonder that it is called a typical miracle of great power.
