The next day, when Lu Yi appeared alone in the nuclear fusion laboratory, Rupert and Hu Feng, who were studying a little guy in front of him, looked at him with some concern, among which Hu Feng asked cautiously: "Boss, are you okay?" ”

"What's the matter, you just think that something happened to your boss?"

Lu Yi took a pair of gloves and put them on, picked up a piece of metal scraps in front of him, looked at it curiously and asked, "This is the metal hydrogen of more than 30 times the TNT explosive?" ”

Saying that, Lu Yi also lightly padded it with his hand, which is heavier than ordinary metal, which is more expensive than any gold and platinum, and it cost 3 billion US dollars to make less than 600 kilograms, which is just enough to meet the use of superconducting coils for a small nuclear fusion reactor and the corresponding thermal expansion engine.

"A total of 587.3 kilograms of metallic hydrogen were prepared, of which 197 kilograms were needed for small nuclear fusion reactors, and the rest was sent to the space industry base to make thermal expansion engines."

Hu Feng talked about the use of metal hydrogen, although this thing is so expensive, but no one cares, after all, it can't be sold like gold, and people don't know how to take it back to play will not necessarily explode.

"This little guy is fine."

Lu Yi put down the metal hydrogen block in his hand, looked at Rupert who was commissioning the ultra-small stellar that was only the size of a 7-kilogram washing machine, and asked: "The schedule of the project has changed, our spacecraft will be completed in about March, but we need to complete the construction of the fusion reactor with the energy core by mid-February, and provide the physical and technical parameters to the aerospace industry." ”

After greeting the leader, Lu Yi's small spaceship became an administrative task, and the aerospace industry would work overtime to design and manufacture and assemble, which originally took more than 7 months or almost 8 months according to the normal design and manufacturing cycle, but it became more than 3 months to complete.

After all, with the nuclear fusion reactor and space engine all handled by Lu Yi, the design and construction of the entire spacecraft can be said to be half complete.

"No problem, this little guy will be able to complete the commissioning in a few days, and the other functional areas of the reactor I have improved the scheme according to the modular design idea on the basis of the first fusion reactor."

Rupert touched his bare head and said confidently: "I have already given the technical requirements and parameters of the relevant plan to your nuclear industry group, and when they finish manufacturing the other functional areas of the reactor, we will put this little guy in it like a Lego toy." ”

The small fusion reactor used on the spacecraft does not use ferrofluid to generate electricity, and the high-temperature exhaust gas from the fusion reactor is directly directed to the thermal expansion engine as a power source.

The power source for the spacecraft's other equipment and instruments will be provided by the PWR generator set, and the latest heat pump module will be used on it, which will be activated to draw energy and send it back to the PWR when the heat accumulated inside the spacecraft is too high.

"By the way, Lu, don't forget to add a small liquid helium circulation machine when you ask them to design the spacecraft, this little guy's external magnetic field coil uses liquid helium cooling."

"Liquid helium?"

Lu Yi asked with some doubts: "If I remember correctly, the superconducting temperature of metallic hydrogen is as high as minus 73 degrees Celsius, and it is enough to use solid carbon dioxide, and there is no need to use liquid helium for cooling, right?" ”

The critical temperature of metallic hydrogen superconductivity is minus 73 degrees Celsius, while the temperature of solid carbon dioxide, commonly known as dry ice, is minus 78 degrees Celsius.

"Stability, helium is the most stable element of all elemental gases that is not easy to react, and the use of helium can reduce the abnormal reaction that may occur between metallic hydrogen and external substances when the spacecraft is subjected to collision impact or ultra-high loads."

Rupert explains: "But the unexpected in space is unpredictable, and the fusion reactor is the core of the entire spacecraft, so this time I used dry ice and liquid helium together.

Ensure that in the event of a problem with the spacecraft's liquid helium cooling circulation system, the dry ice can continue to maintain the superconducting temperature of metallic hydrogen to ensure the stable operation of the nuclear fusion reactor. ”

"Yes." Lu Yi nodded, the cost of the entire spacecraft is as high as 6 billion US dollars, and it is okay to have a little more insurance measures like this.

After all, now high-energy light weapons and ray weapons are still in preliminary research and have not yet entered practical use, and they do not have much resistance and defense against various meteorites and other things in space.

If you really want to be hit by a high-speed meteorite in space and cause problems with the liquid helium cooling system, and the nuclear fusion reactor shutdown spacecraft becomes a living coffin in space, then there is really no place to cry.

After chatting with Rupert for a while, and paying attention to the situation in the materials laboratory, Lu Yi turned around and walked out of the laboratory building and went back to his residence.

Pouring himself a glass of water, Lu Yi approached Zhang Qing and Professor Lin, who were studying and analyzing gravitational wave data, and asked in a tone that was almost grinning: "The spacecraft will be completed in about mid-March, how is the production of our large laser interferometric gravitational-wave observatory?" ”

"Look at the mailbox yourself, the relevant progress will be sent to your mailbox every day by the tracking team on Senior Sister Xu Ying's side."

Zhang Qing raised his head and glanced at him, but did not give a good face, and then lowered his head and pointed to a problem found on the data to discuss with Professor Lin.

"Okay."

Lu Yi smacked his lips helplessly, of course he knew the manufacturing and production progress of the Gravitational Wave Observatory, but he just wanted to find a reason to talk.

Although the several kilometers of vacuum tubes were cut off into spacecraft that could be transported into space, technical difficulties were encountered in the process of assembling and restoring the original vacuum performance in space.

However, under the stimulus of banknotes, the technical problems involved were quickly solved by the manufacturer, probably less than 3 months, from the order before and after 7 months to get it.

"That's right."

Sitting on the sofa a little helplessly, Lu Yi seemed to remember something, and said to Zhang Qing and Lin Meng: "After the spacecraft is completed, I plan to let it fly to Mars first, and send some exploration equipment to Mars for relevant exploration."

This time in the northwest, they gave me a copy of NASA's Mars exploration data, and the data showed that the InSight probe that landed last year proved that there were traces of civilization on Mars. ”

Are there traces of civilization on Mars?

At this moment, Zhang Qing and Lin Meng couldn't stay calm anymore, raised their heads and asked a little seriously: "Is this thing confirmed?" ”

"When did I lie to you." Lu Yi said angrily.

Zhang Qing rolled her eyes and didn't want to pay attention to Lu Yi's words, and instead said seriously: "We don't have high-precision planet exploration equipment, and we have no experience in planet exploration. ”

The science and technology tree of a civilization involves immeasurable technologies and instruments.

No matter how awesome Lu Yi is, no matter how powerful Zhang Qing is, and no matter how abundant the capital resources provided by Li Yashan's Tomorrow Group are, the entire laboratory can only participate in research is only a small part of the entire civilized science and technology system.

Perhaps this part of their research represents the future of civilization, but this does not mean that they can take out any scientific and technological equipment in the laboratory, nor does it mean that they understand all the knowledge in any field.

Even if Lu Yi has a system, the existence of the point limit can't let him do whatever he wants, but he needs to read and study hard every day to really improve himself.

"It is said that our spacecraft landed on Mars, but in fact we delivered the goods, and the specific exploration instruments and exploration plans will be dealt with, which is a cooperation and we don't need to worry so much."

Lu Yi explained the situation slightly, stood up and asked, "What do you want to eat at noon?" Today, your Chef Lu will cook, and wait for Yashan to come over and eat together......"
