When he came out of the office, it was already dark, he walked out of the office first, and walked around the factory, and now except for the staff on night duty, the rest of the employees have basically left. Pen % fun % Pavilion www.biquge.info

And after he took a turn, he also walked out of his factory, got in the car and prepared to go home.

The car was on the way home, and he leaned against the car seat. You can still faintly hear the screeching sound of the ion engine.

Hearing the screaming sound of the ion engine, Zhu Lei was very excited, after all, this was the first aero engine produced by their factory.

As long as this engine is successful, then there will be a solid foundation for the transformation of the factory to the aerospace side in the future.

After starting the engine of the car, a person slowly drove out of the factory area, driving alone on the way home, looking at the starry lights in the dark sky in the distance, as long as there is an engine, if you want to send people to space in the future, everything else has become much simpler.

Although manned space technology has various technical difficulties. But at least a solid step has been taken.

Manned space technology is the use of advanced scientific and technological means to send human beings into space. Engaged in various explorations, research, experiments, production in space. and technology for military applications.

The purpose of manned space technology is to expand the scope of human life from the scope of the home star to the infinite universe, so that human beings can have a broader and deeper understanding of the universe. And it can also develop the universe, rich resources, of course, with the current level of science and technology on the earth, it can only be in low-earth orbit, even so, on the current earth capable of space activities, there are only three superpowers: the United States, the polar bear and the Ming Empire.

And in his previous life, there were only a few countries in the world that could have independent space capabilities, and if the others were also counted, then Europe, Argentina and Japan should be counted.

In order to realize manned space technology, it is necessary to break through three major technical problems, the first is the high-thrust carrier rocket technology, of course, because he now has plasma thrusters, so he now has the ability to directly send dozens or hundreds of tons of objects into space.

The second is the safe return technology of satellites, which has been very mature in the Ming Empire, and has rented a plasma thruster, which can even travel directly between space and the ground.

The last technology is good environmental control and life support system technology, which is also the biggest problem he faces. It is also a problem faced by all countries in the world that have the ability to conduct manned spaceflight.

The environment in space is extremely harsh, high vacuum, high lack of oxygen, cosmic radiation, temperature differences, and all kinds of unfavorable factors will cause great harm to the human body. Therefore, human beings cannot directly survive in space, and in the face of extremely harsh conditions in the universe, a safe and reliable environmental control and life support system is extremely necessary.

In addition to environmental control and life support systems, if humans want to operate in space, they must have corresponding spacesuits to protect astronauts.

All kinds of spacesuits in his previous life were very bulky and bloated, so he didn't want to use such spacesuits.

After thinking for a while, he suddenly thought of the exoskeleton armor technology that various countries had been testing in his previous life, and it had appeared in various movies, television, and games, and exoskeleton armor technology was also a kind of robot technology.

Of course, exoskeleton armor involves a lot of high-end technology, and in his previous life, countries began to develop this kind of equipment very early, but before Zhu Lei crossed over, there was still a country that had a practical launch.

In fact, in the previous life, the progress of research in various countries was actually about the same, and the most important thing was that it was similar to the electromagnetic railgun, and the most important thing was the issue of energy, and other countries were almost stuck in this technology.

Thinking about it, Zhu Lei arrived home after a while, he got out of the car and walked into the living room, only to see his sister and Zhang Rou already waiting for him in the living room, Zhu Lei quickly walked over to them and said, "Yali, Xiaorou, let's eat!" You've all been waiting for a long time! ”

"Brother, you're back." Seeing Zhu Lei walk in, her sister Zhu Yali stood up, walked to Zhu's side and said.

"yes, you're all starving! Let's go eat! As he spoke, he took Zhu Yali and Zhang Rou, who had already walked to his side, and walked towards the restaurant.

"Brother Lei, my mother called me today and said she wanted to come and see you." When he walked to the restaurant, Zhang Rou on the side suddenly spoke.

Hearing Zhang Rou's words, he was stunned for a moment, then slowly turned his head, then he slowly turned his head to look at Zhang Rou, and then turned back, and after waiting like this for a while, he suddenly reacted and said, "Xiaorou! What did you say? Your mom she's coming to see me! What you say can't be true, don't scare me. ”

"I'm telling the truth, but I don't know when he's coming, and he didn't tell me when he's going to come, he just said he's going to come over for a while." Zhang Rou replied softly to Zhu Lei's words.

Zhu Lei stood there and thought for a while, and then said to her: "Okay, if he comes over when, you notify me one day earlier, and I can pick her up." Anyway, you can't hide from it. The ugly daughter-in-law always wants to see her in-laws. ”

He thought about it for a while, but he didn't think of any good way, after all, his mother-in-law wanted to come to see his son-in-law, which must be unstoppable, and he had been with Zhang Rou for so long, and he also asked his parents in the morning to propose to Zhang Rou's family, and his parents had already agreed, so there was nothing to be afraid of.

With that, he pulled the two of them and continued towards the restaurant.

After eating, my sister and Zhang Rou went back to their own rooms, since the last drunken incident, Zhang Rou resolutely did not sleep with him until he got married, so there was no way, he could only sleep alone during this time.

After returning to the room to take a shower and brush his teeth, he looked at the time, it was less than nine o'clock in the evening, so he simply came to the plane mall, during this time, basically every night, he would stay in the plane mall for a while, by the way, in the market of the plane mall to see what technology suited him, but in fact, during this period of time, in addition to titanium alloy technology, there is really no good technology, then the price is too high, then it is not suitable for humans, or there are a lot of ancillary conditions, so during this time, He didn't buy any good technology, but he insisted on coming every night.

After coming to the mall, he first carefully searched for some information about the technology that Xiao Lori had left behind today, but he didn't find that it was suitable for the technology of the earthlings, so he chatted with Xiao Lori for a while and then returned to the room, after all, if it disappeared for too long, it would inevitably attract the attention of others.
