Chapter 2328: a hand

Cheng Rulong smiled bitterly and said, "Young man, although I am in charge of the rocket system, I have a good understanding of the space station system. Your question... how do you say it? In fact, it is not difficult to simulate the gravity environment in space, you You should have seen some sci-fi movies, right? The long-distance spaceships or near-Earth space stations in it all use the continuously rotating annular structure to simulate the gravitational environment. In fact, centrifugal force is used to simulate gravity. Technically, it can be said that No difficulty at all, but the problem is..."
Speaking of this, Cheng Rulong couldn't help but sighed and said, "Speaking of which, those of us who are involved in rockets are incompetent! If we want to build such a simulated gravity environment, the annular structure is bound to be very large. With our current rockets The thrust can only be sent into space little by little like ants moving, and then docked and assembled in orbit, which will take a lot of time, and more importantly, the ring structure must be large enough to stably simulate similar The effect of gravity, but the cost of launching rockets is extremely high now, and the funds needed to build such a circular space station are beyond the reach of any country in the world..."
At this time, Song Lao said from the side: "Old Cheng, don't take everything on your own. What does this have to do with you guys doing rockets? I want to say that this is the result of weighing the pros and cons. On the one hand, it costs the whole country. Zhili builds such a ring-shaped space station; on the other hand, it is launched every six months to allow astronauts to rotate, and the effect is the same as long-term residence! And... the significance of the existence of the space station is largely because of that microgravity There are many scientific experiments that need such an environment. After simulating gravity, what is the difference between it and the earth? Did you go to the space station just to watch the scenery at a height of hundreds of kilometers?"
Cheng Rulong said with a smile: "Actually, we have imagined, and even have a rough plan, that the space station that simulates the gravity environment will be composed of two parts, one part is a traditional cylindrical module, and there is a microgravity environment, which is used to undertake scientific research. The other part is the annular cabin, which is mainly the area where astronauts rest and live. The cylindrical cabin is located in the center of the circle, and the annular cabin rotates continuously around the cylindrical cabin. We even designed the junction The plan uses a similar nesting plan, which can not only ensure the sealing of the interface, but also connect the two modules, so that the astronauts can travel freely."
"Have you really done research in this area?" Song Lao was also a little surprised.
Cheng Rulong smiled and said: "It's mainly theoretical research, which can be considered groundbreaking and conceptual! With the current situation, it is naturally unrealistic to build such a complex space station, but our plan may be able to give later What about some references and inspirations? With the current speed of technological development, I think our vision may be truly realized in a few decades. It's a pity...you and I can't see it..."
Xia Ruofei couldn't help asking: "Academician Cheng, so this space station that simulates the gravity environment is actually very important. If it can be realized, it will be of great significance?"
"Of course!" Cheng Rulong said without hesitation, "Let's not say that if it can be successful, then we will be the first country in the world to realize the construction of a simulated gravity environment in space. In terms of practicality, it is also very important, because the future of mankind is bound to move towards In deep space, and in the case of long-term navigation, it is essential to simulate the gravity environment. If we can build such a simulated gravity environment space station in low-Earth orbit as soon as possible, we will take the first step in deep space navigation. A lot of preliminary research can be carried out…

Speaking of this, Cheng Rulong couldn't help but chuckle: "But this is just an assumption, the reality is... In the next 50 years, not only China, but also any country in the world may not be able to realize this grand vision. If five It is quite remarkable that it can be achieved in about ten years. I think that in the future, it is likely that many countries will jointly complete this work. Only in this way can we hope to achieve the goal within a hundred years!"
Xia Ruofei nodded with a smile and said, "It seems that this is really difficult, but we are just chatting, and we are not responsible for the law, haha..."
Although Xia Ruofei said something lightly, but Song Lao moved in his heart and couldn't help but glance at him.
Then, Song Lao asked calmly: "Old Cheng, I have a question that I'm curious about. If... I mean, if we don't consider the launch cost, we can build such a ring structure in a short period of time. A simulated gravity space station with a cylindrical structure?"
"It's not difficult to just build the structure on Earth." Cheng Rulong said, "Although the cost is also very high, after all, this composite structure is very large, and the construction running in space requires safety and stability. They are all very high, and the cost of materials alone is very high, but... Compared with the cost of splitting and launching this construction, it is simply a drop in the bucket!"
"Hmm! That is to say, without considering the launch factor and cost, with our country's financial resources, we can build this combination. I mean, there is absolutely no problem with the combination that can actually run in space?" Song Lao asked. road.
"Of course!" Cheng Rulong said with great certainty, "but this assumption is meaningless. The combination will eventually run in space. If the launch factor is not considered, is it built to eat ashes in the warehouse?"
"I'm just chatting casually..." Song Lao said with a smile.
Then he quickly changed the subject and did not continue to talk deeply, and Xia Ruofei naturally would not ask this question on his own initiative.
The three sat and chatted for more than two hours. Of course, it was mainly the two old people who were talking. Xia Ruofei's main task was to make tea.
Then, Cheng Rulong stood up a little bit still, and said, "Old Song! I have to go! There are two projects in hand to catch up with the progress, and today I'm just here to steal some free time, I... I'm just working hard!"
Song Lao and Xia Ruofei naturally also stood up.
Song Lao asked: "You don't have to eat before you leave? It's almost time for dinner, so don't you have to eat when you go back?"
"No!" Cheng Rulong said, "I'll just make do with it in the lab!"
The two had been friends for many years, and Lao Song naturally knew Cheng Rulong very well, so he did not continue to keep him, but called Director Lu and asked him to send Cheng Rulong out.
Cheng Rulong smiled again and said to Xia Ruofei: "Xiao Xia, I didn't expect you to be so interested in aerospace. I heard Lao Song say that you are a very successful entrepreneur. If there is a chance in the future, I hope you will give more support to the aerospace industry! "
Xia Ruofei nodded with a smile: "Sure! Certainly!"
Cheng Rulong then nodded to Song Lao again, and then left with Director Lu.
After Cheng Rulong left, Xia Ruofei and Song Lao did not speak at first, Song Lao sat there thoughtfully, while Xia Ruofei was still concentrating on making tea.
He picked up the justice cup and filled the tea cup in front of Song Lao.
At this time, Song Lao suddenly asked: "Ruofei, if the combination that Lao Cheng said just now is built on earth, you have a way to send it into space, right?"
Xia Ruofei didn't hide it either, nodded lightly, and said, "To tell you the truth, I can indeed do it!"
Song Lao nodded approvingly and said, "I guess that's it! Otherwise you wouldn't ask that... Ruofei! I know you have many abilities that ordinary people can't imagine, and I was able to come into contact with some of them because of my work. As for the internal information, I know that there have always been some strange people, their methods are superb and their skills are beyond the imagination of ordinary people. If Fei, you should be the same as them, right?"
Xia Ruofei was silent for a while, and said, "Grandpa Song, I don't know if the strange people you are talking about are the same as me, but... Some people think that they are the so-called fairy methods of legends, and I have indeed mastered some..."
After all, Song Lao is not a person in the cultivation world, so it is not convenient for Xia Ruofei to reveal too many things about cultivation to him.
However, Song Lao's grasp of the situation is obviously more than Xia Ruofei imagined. Maybe he has already guessed in his heart, so he is not very surprised.
He just took a deep breath and said, "Ruofei, if I want to ask you to help the comrades in the aerospace industry to send such a combination into space, would you like it?"
Xia Ruofei didn't hesitate, nodded and said, "Yes! Didn't you just teach me to be loyal to the country? It's my honor to make a little contribution to the country's aerospace industry! But..."
When Xia Ruofei said this, he couldn't help but change the conversation and said: "Grandpa Song, there are actually many hidden dangers in doing this. If you propose to spend a lot of money on the earth to build such a combination, I am afraid there will be a lot of doubts. .In addition... it is not too difficult to send it into space, but how to deal with public opinion at home and abroad? A normal launch cannot be concealed. If we don't have any launch activities, we have built such a huge one in space out of thin air. With a space station that simulates a gravity environment, the voices of various speculations may flood our country at once, and it is not easy to deal with."
Song Lao nodded slightly and said, "I have also considered what you said, so I just asked for your opinion first. Whether to do it or not, and how to do it, it is up to the upper-level decision."
Xia Ruofei nodded when he heard the words: "Understood! Grandpa Song, I also express my position: If you need me to do this, I will not turn back!"
"My good boy! What I want is your words!" Song Lao laughed and said, "If Feifei, I'll tell you what you said, my grandfather should have a few drinks at noon today!"
"Are you sure you're not just looking for a reason to drink?" Xia Ruofei couldn't help asking.
"You kid!" Song Lao smiled and said, "I have regular checkups, and now my physical indicators are similar to those of people in their 50s or 60s, and they are still getting better! What is a drink? Even the health doctor has not restricted me!"
"Yes! You said so, then I have to sacrifice my life to accompany the gentleman!" Xia Ruofei said with a smile.
He thought about it for a while, and then said: "By the way, Grandpa Song, there is one more thing... that's it! I have to work hard, because I still have some more important things to complete. If I wait too long, I'm afraid It won't be... This will test the reliability of the plan that Academician Cheng just said, and the production speed of our aerospace industry enterprises..."
Song Lao nodded and said, "When is the slowest time to complete it?"
Xia Ruofei thought about it and said, "One year! If it is more than a year, I'm afraid I won't be able to wait any longer..."
One year is the limit that Xia Ruofei can wait for. If he stays on Earth for more than a year, even if Daoist Qingxuan won't say anything, he can't make it through himself. After all, the cultivation world in Shenzhou is always facing a crisis.
"One year, right? Okay! I see!" Song Lao nodded and said, "I believe that our scientific and technological workers will be able to complete this task within one year!"
"Then I'll wait for the good news!" Xia Ruofei smiled.
"Any more requests? You can put them together!" Song Lao said with a smile, "If you pass this village, you won't have this store!"
Xia Ruofei thought about it and said: "Request... Then I will mention a little more! I don't care how the assembly is produced. As long as it is completed within a year, I will definitely fulfill this promise. But... The assembly needs to be assembled at the location I designated. , After the assembly and testing are all completed, all personnel must be evacuated, and monitoring equipment is not allowed to be left, and then leave all the rest to me, I will send it into the designated orbit as required, and give the combination An initial velocity sufficient to maintain it in orbit."
Song Lao was not surprised by Xia Ruofei's request.
In fact, when Song Lao proposed to the above, he didn't even say Xia Ruofei's name. The purpose was the same as what Xia Ruofei just asked, that is, he didn't want Xia Ruofei's identity to be exposed and avoid some troubles.
Therefore, Song Lao immediately said: "Yes! You can choose the location of the assembly test slowly, and just tell me after you have chosen it!"
"Okay!" Xia Ruofei said with a smile, "I'll go back to research and find a place with sparse population and strong confidentiality. But in general, I tend to prefer the western part of China."
"Okay, you can contact me directly and tell me the latitude and longitude coordinates!" Song Lao said very readily.
After saying this, Song Lao's happiness was beyond words. During lunch, he actually opened a limited edition bottle of good wine, the Drunk Eight Immortals.
This wine is naturally Xia Ruofei's filial piety to Song Lao, and now it is used by Song Lao to borrow flowers to offer Buddha.
