Deep Space Fleet

Zhang Yuan nodded, indicating that he could understand.

连 Even lazy goods like Li Zhendong, this time has become hurried, want to make some achievements.

When I first boarded the spacecraft, although I had parting pains, I also had a sense of anticipation and freshness.

But now, this sense of anticipation is slowly passing by, the pace of life in the spaceship is getting faster and faster, and the number of people chatting on the roadside is obviously fewer.

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

This sense of security is seriously inadequate.

虽然 Although large, warm and comfortable, the "Earth Age" is still not comparable to a planet like 4.6 billion years in the universe.

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

Human, small and fragile creature. An ordinary person, if there is no space suit, naked in the universe, 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 another 15 seconds, the person will fall into a coma, and if he can't survive, he will only be left to fate.

Because everyone knows this common sense, as the mother star is far away, he has a sense of uneasiness involuntarily.

Even Zhang Yuan himself had such anxiety. He often convulsed in his dreams, woke up, and found that he had just a nightmare, and fell asleep again.

As a result, Zhang Yuan's entertaining gossip became a life-saving straw, and people talked about it. Because people want to deliberately create a loose environment similar to the earth during the intense work to comfort their fear subconscious.

This kind of subconscious change is normal. There are some psychologists in the spaceship who are responsible for controlling this aspect. Large-scale group events are often held within various communities, not only to increase group awareness, but also to have a little meaning to treat cosmic phobia.

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

所以 "So, to find a life partner, it is best to find a more beautiful girlfriend. Two people can also complain about each other, and one person can only resist it. Unless your mental quality is particularly good ..."

Here I am, again.

Zhang Yuan quickly turned his head, as if he hadn't heard.

"By the way, after the spacecraft has successfully turned, the nuclear-powered engine will be turned off, and it will be turned on again after six months. If there is any observation experiment, you only have one day today ... or you can also visit the lateral engine. "

Zhang Yuanyuan nodded, Brother Zhao is indeed a very good instructor. Even when the experimental conditions are very barren, I can always make suggestions that fit the timing.

In this respect, he is far more qualified than Academician Ding. Until now, apart from the regular meeting at the beginning of each month, Zhang Yuan hasn't seen Ding Zhaodong several times ... even if I saw him, I couldn't say a few words.

In the next few minutes, he hurriedly came to the lateral engine observation room, where there are blocks of bright display screens, and many staff members are focusing on parameter changes.

From one of the display screens, you can see that a long plasma flame sprayed from the wings, causing the entire ship to spin slowly.

的 The angular velocity of the spacecraft's rotation is very low. It can complete 180 degrees of rotation in more than twenty hours, so everyone basically does not notice it.

Look again at the second screen, which shows the plasma turbulence in the reactor. At extremely high brightness, even if it has been specially treated, it is still a bit dazzling.

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

"Hi, Zhang Yuan!"

"Hi, hello." I greeted a few colleagues, and no one came to care about him. Zhang Yuan researched these screens by himself.

The high temperature generated by thorium nuclear fusion will vaporize the metallic sodium in the furnace wall. These hot sodium vapors can perform 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 spacecraft.

The tritium principle is simple to say, but this nuclear engine device is the crystallization of the highest wisdom of mankind. It's so complicated that every part, even the welding method, can write a dissertation!

It is also the second generation of human fusion engine.

After the fusion of a helium 3 nucleus and a deuteron, it produces a helium 4, a proton and huge energy. Since it does not generate neutrons, it is cleaner and more stable than deuterium and tritium fusion, and maintenance costs are lower.

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, the cost of mining is too huge. Calculating it, you will find that fusion with helium-3 is not as cost-effective as using the first generation of deuterium and tritium fusion.

However, establishing a space base on the moon is not useless, because the moon is the most suitable natural base for space industry production. UU reading books www.uukanshu.com Even if the helium-3 is ignored, the moon has great development value.

Until the Jupiter base was developed later, the second-generation nuclear engineering helium-3 fusion did not really gain popularity.

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

In the observation room, a fellow named John Wilson spoke.

"Really? The ordinary method of wavelet transform ..." Zhang Yuan was very proud to hear his father's name.

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

维尔 John Wilson is a high-tech talent who specializes in plasma physics. He sighs that human technology is too bad, too naive and so on.

Alas, he is actually a very simple person.

"Isn't it very constrained now? The current method is quite stable. Theoretically, there will be no accidents for dozens or hundreds of years." Zhang Yuan was slightly unconvinced that John was questioning his father's achievements.

"Yes, it is very stable indeed. But in your ancient Xia language, it is a great miracle to restrain these plasmas in a very rude way. It is really not wonderful!"

维尔 John Wilson said very surely: "If only a magnetic field of 10 T is used to constrain, I can guarantee that these high-temperature plasmas will still splash on the furnace wall and stop the entire device!"

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

Coupled with the supercomputer that constantly monitors these plasma turbulences, and uses super powerful computing power to maintain the balance of turbulence, it is no wonder that it is called a typical miracle.
