Chapter 269 The Space Shuttle's Body Armor

"Uh, hello, Dr. Li."

"Well, hello you guys. Just so happens that the magnetic field generator is about to be inspected, so you can come and have a look. After all, it won't take long to use it, so it's still necessary to understand some of this stuff.

I also saw it. We went to the safe room next to us to observe the inspection process."

The security room is a room completely isolated from the research room here. In the room, the light and shadow of the other side are projected 100% through stereo projection technology. In addition to being safer and illusory, there is no difference in anything else.

In the original laboratory, automated robots have completely replaced human labor.

The test procedure is undergoing the final simulation and the inspection is underway.

"Dr. Li Chunhua, do you have time now? I want to ask about the principle of this magnetic field generation device. He looks like a huge electromagnet." At this time, Liu Haibo asked.

"Okay, there is still some time, I'll talk about it roughly. First of all, what you said is nothing wrong. This is a huge electromagnet; but it is not an electromagnet in the traditional sense. It was established by imitating the core magnetic field of the Earth. The first to build this model was the US Geographic Exploration Agency more than 30 years ago.

We do not deny that electromagnets are easy to make and have strong magnetic force. However, in space, we need not only the strength of magnetic force, but also the range of the magnetic field is large enough. It seems that this is the same, but different. The magnetic field of the electromagnet is only attached to oneself; but the most powerful part of the earth's magnetic field is at a height of thousands of kilometers and extends to space for more than 100,000 kilometers, almost ten times the diameter of the earth.

In space, if we can withstand cosmic radiation such as solar wind, we must have the same powerful magnetic field protection as the earth. Considering that the space shuttle's portable energy is limited, we borrowed from the inventions of the United States to establish an artificial magnetic field generation device.

According to the existing authoritative speculation, the core of the earth is an iron core that still maintains solid approximately colloidal under high temperature and high pressure. Around the core is a large amount of liquid metal flowing, and outside the metal, it is magma, and then the mantle crust, etc.

And the current installation, we imitate the core of the earth.

First of all, its core is an iron pipe you see hanging from outside. We use that instead of the steel core.

Outside, we use liquid metal sodium to replace the melted metal stream to simulate the melted liquid molten iron on the earth.

In fact, sodium is not the metal with the lowest melting point, but it is the largest and lowest-cost low-temperature melted metal that can be obtained by technology at present. Moreover, it is relatively easy to control and has better ionic properties.

Our experiment is that the high-speed rotating liquid sodium rotates around a high-purity pure iron core to create a strange and powerful magnetic field.

Compared with ordinary electromagnets, it has a magnetic field protection layer with a theoretical range of up to 1,000 kilometers and will be able to defend against most of the cosmic radiation. However, its power consumption is extremely low, only one percent of the electromagnetic field strength of the same level. This is an amazing discovery. As for the issue of energy consumption, I think I don’t need to say more about the two best pilots.”

"Yes, energy consumption in space is very important. But I still want to ask, how much energy consumption is about this magnetic field generator?" Liu Haibo was meticulous.

"Uh... it's a bit big..." Li Yuzhang suddenly felt a little embarrassed, "To maintain such a huge magnetic field, it takes almost one million kWh per hour, which is comparable to the S001 model engine. However, if the space shuttle carries more batteries, it is still OK. This is already good.

You know, he can defend against 90% of the sun's radiation."

Liu Haibo's mouth twitched a little. The power of 1 million degrees is really large. This is a bit unbearable for the current space shuttle. Moreover, judging from Li Yuzhang's appearance, it is probably the lowest power consumption!

"Okay OK, I'll introduce the principle of this thing to you. When you are in space, if something goes wrong, you may repair it yourself." Seeing the eyes of the two people, and the suspicious eyes of Zhao Qingyun and Sun Feiyu next to you, Li Yuzhang finally decided to change the topic. "As mentioned above, it is a simulated earth's magnetic field, but because the earth is huge, even if the earth rotates slowly, the sub-magnetic field is still huge.

But our magnetic field generator is different. It is very small. As you can see, it is only 3 meters. Compared with the core of the earth that is thousands of kilometers, it is really pitiful. According to the magnetic field formula, we have to increase the flow rate of liquid metal sodium, and for a sufficient magnetic field, the speed of metal sodium is very fast. In this small space, it contains more than 15 tons of liquid sodium, and is ionized and liquefied under a strong current, maintaining a speed of up to 500 meters in seconds.

So, this thing is actually a bit dangerous.

In addition, the magnetic field that occurs, the magnetic layer with the maximum intensity, will be at a distance of 100 meters from the core, and the impact on the human body will be minimal. Moreover, because the magnetic field range may extend to 1,000 kilometers away, including the magnetic field range with protection capabilities, it can defend against objects within a range of at least 10 kilometers from cosmic radiation. This is definitely the most practical radiation protection technology in technology now, and it will also be the main cosmic radiation protection technology and mainstream protection technology in the next hundred years. It will wear a layer of bulletproof vest for the space shuttle."

"Then why is the iron pillar in the middle rusted?" Li Canglan asked. This thing is very useful, everyone admits it; but it is really ugly!

"This is nothing to do!" Li Yuzhang shrugged, "Only pure iron can meet the current requirements; but the rust-proof ability of pure iron is really limited. But don't worry, the current situation is only for experiments; when the real application stage, it will be corrected. At least, it will spray a plastic rust-proof layer."

"Thank you." Li Canglan nodded. In fact, in the expert company, the researchers are the highest among the same level. Therefore, the two are still very grateful for Li Yuzhang's detailed and inner explanation. In particular, this thing was invented for themselves - at least now.

"Okay, everyone, we will conduct the test next. See if this magnetic field generator is effective; if it is effective, its ability. Because it is a test, we will conduct the test at a minimum power of 50,000 degrees. It cannot be lower than 50,000 degrees, and metal sodium cannot be melted. You must pay attention to one problem when you are in space, that is, you cannot let the sodium cool, otherwise it will take at least five minutes to reheat. Five minutes is enough for the solar storm to sweep you."

"Yes." Liu Haibo and the others nodded. We should pay attention to this. Once this happens, it is necessary to verify it with life.
