Chapter 606 The Difficulty of Modular Construction (Subscribe)

The higher the technical content, the higher the requirements for engineers, and the more meticulous the pursuit of details, and there is nothing wrong with it.

Aerospace aircraft can almost be said to be a collection of the highest technology on the earth today, the flower of the earth's industry, the brightest pearl in the crown of the earth's industry, especially so.

Qin Yuanqing stayed at the aerospace aircraft manufacturing base for three days before leaving, and then came to another base, this base is dedicated to the 'Shuanghuan Space Station', that is, the 'Shuanghuan Space Station' modular construction planning and design institute, specializing in Study how to carry out the modular construction of the 'Double Ring Space Station'.

For a big guy like the 'Shuanghuan Space Station', it is doomed to be impossible to construct a project like this on the ground. Through modular construction and automatic assembly, just like the 'Tiangong' space station, each module is built one by one, and after launching into space , and then connect the cabin to the cabin, so as to facilitate the construction of the 'double ring space station'.

Here, a special laboratory has been established. The laboratory is in a state of weightlessness, simulating the space situation, and then the R&D personnel conduct module assembly through experiments one after another, and determine the modularity and assembly sequence of the 'Double Ring Space Station' to ensure The 'Double Ring Space Station' finally realized the design function.

Even, this modular construction planning and design institute can mobilize supercomputers to carry out simulations, simulations, modeling and experiments again and again.

"Commander-in-Chief, you are welcome to inspect the work." Feng Rufeng, Director of the Modular Construction Planning and Design Institute of the 'Shuanghuan Space Station' greeted Qin Yuanqing in person.

Although located in Tsinghua Park, the design office didn't even put up a signboard, and the entire design office directly used a dilapidated old building.

"How is it? Have you completed the modular simulation?" Qin Yuanqing asked.

In two more years, the "Double Ring Space Station" project will enter the substantive construction stage from the research and development stage, and other aspects are almost ready, and now the modularization is missing. According to the given time limit, modularized research and development All design and development work must be completed before the May Day holiday this year.

"Most of them have been drawn up, and now the only thing that needs to be done is the connection between the small ring and the big ring. There are always connection problems in this connecting corridor. The automatic connection is simulated by the supercomputer, and it all ends in failure." Feng Rufeng Said.

The [-] people in the entire design office have been transferred to the present. For eight years, they have all invested in modular research and development. They have overcome difficulties one by one and created technological breakthroughs one by one. In order to complete the research and development, they have We also independently develop engineering software suitable for work.

Although there are only [-] people in the design office, there are [-] colleges and universities behind them, and the research and development tasks are dismembered and handed over to colleges and universities for research.

"Let's go, let's go and see!" Qin Yuanqing was interested. According to his idea, the modular construction design work should be relatively smooth, but now he is stuck and unable to move forward.

Feng Rufeng brought Qin Yuanqing to the meeting room, and then asked the technicians to turn on the LCD screen, which was connected to the computer, and immediately saw the rockets transporting the modules built in various factories, into space, and came to the setting The good orbits are then put together one by one under the control of the ground command center. Under the condition of acceleration, the small rings of the 'double-ring space station' are forming at a speed that can be discerned by the naked eye.

In the early stage, the modular capsules were launched into orbit by rocket launch, but it changed in 2035, and it became a transport-type aerospace plane mode, sending the modular capsules into space, and then splicing them together, just like stacking In general, in 2040, the small ring space station of the first ring was built.

Subsequently, from 2040 to 2050, the space station of the big ring was continuously spliced ​​and formed.As a result, in the last part, there was a problem with the connection between the central cabin and the big ring!
"Commander, this is the problem. We have tried various methods, but there is no way to solve this problem." Feng Rufeng clicked the pause button, pointing to a part of the construction of this link.

Under the supercomputer simulation, if there is a problem here, it means that there is a high probability that this problem will also occur during the construction process.

Qin Yuanqing pondered for a while, looking at the magnified part on the LCD screen, his thoughts started to run quickly.

For the 'double ring space station', the two slightly larger places in the middle are the energy cores of the big and small ring space stations, where two 'Golden Crow Devices' and the required magnetic fluid generators are placed. It is the energy core of the entire 'Double Ring Space Station' and bears the energy required for the operation of the entire 'Double Ring Space Station'.

The other cabins in the front, back and middle seem to be axes and rotation axes, but they are actually experimental cabins, which are responsible for various experiments and scientific research tasks in space in the future, and there is a complete weightlessness in space.

The two large and small rings are the working area, living area, entertainment area, and also where the aerospace plane and the space station are connected.

Those ports are all reserved for connecting with aerospace planes in the future.

The corridor is the channel for the astronauts to go to the energy cabin and the experimental cabin, and it is also the channel for the energy cabin to transmit energy to the large and small rings. Because this part involves the power grid, it needs to rely on the astronauts for construction.

Therefore, once the corridor cannot be completed, it means that the large and small rings have no energy source, and they cannot go to the experimental cabin.

"Director Feng, why don't you demonstrate that the connection between the corridor and the front and back is built first, and then the middle is constructed?" Qin Yuanqing pointed to the place marked in red.

"Commander-in-chief, we have tried this plan before, Mr. Yang, you call out the No. 3 plan here!" Feng Rufeng said, and then asked an engineer to call out the corresponding plan.

Qin Yuanqing saw that the video during the construction began to change. It became connected from both ends first, then built from both ends to the middle, and finally connected in the middle. As a result, he encountered new troubles, that is, the construction in the middle was not enough. stand up.

Qin Yuanqing couldn't help showing a look of contemplation, this problem didn't appear in other places, why did it appear here?

He asked someone to bring the paper, and began to analyze it step by step, only to see random scribbles on the paper, like ghostly drawn symbols, marked with symbols one by one.

The previous supercomputer simulations were all simulations without considering modular construction. At that time, it was completely feasible theoretically.

But now in modular construction, many forces or speeds that were previously negligible are no longer available.

Sure enough, after some calculations, Qin Yuanqing found that when the front and rear ends are connected, because the speed is different, and the modular construction is a whole piece, this leads to the different speed and force when entering, so it cannot be carried out. building.

In such a case, it has to be controlled by external force, such as a robotic arm, or astronauts to manually connect.

The previous space manipulators were mostly used to capture modules and then build them, but they never directly participated in the connection. The connection basically relied on the ground command center for operations.

"It seems that this place will have to be conquered by the cooperation of robotic arms and astronauts! Or the technology will be further improved in the future, and there will be a better way." Qin Yuanqing muttered to himself.

Next, Qin Yuanqing asked Feng Rufeng to simulate in the way of robotic arms and astronauts to see the simulation situation.

"Try this question for a while, and let me know the result as soon as possible." Qin Yuanqing said.

Although it is said that this corridor problem, even the small ring part, will not be encountered until a few years later, but in the development stage, these discovered problems must be solved, so that fewer problems will be encountered during the construction process .

Of course, as we all know, design is one thing, and actual construction is another. At a height of about 400 kilometers from the ground and under the conditions of the space environment, it is destined to encounter various problems during construction, and these problems All need to rely on the wisdom of engineers to solve.

Qin Yuanqing would never think that, theoretically, there would be no problem with supercomputer calculations, but actual construction would be fine, that would be too naive.

"Okay, I'll let you know the result as soon as possible!" Feng Rufeng nodded.

Afterwards, let the person in charge of this part start to invest in the formulation of the plan. These people are engaged in this job, and their superficial identity is to be a researcher in the university. Even to their relatives, they say they are doing research in Shuimu University. What kind of research are you doing? Sorry, you can’t say, and you can’t ask.

And everyone knows that Shuimu University is involved in a lot of confidential research, so their family members can understand it better.

Leaving the 'Shuanghuan Space Station' Modular Construction Design Institute, Qin Yuanqing took a walk in Tsinghua Park. Since the construction of Shahe Campus was completed, Tsinghua Park has only undergraduate students, as well as a very small number of scientific research institutions, graduate students, doctoral students and absolutely Most of the scientific research institutions have moved to the Shahe campus.

Walking on the path of Tsinghua Garden, Qin Yuanqing watched boys and girls holding hands and chatting in low voices, and couldn't help showing envy. In his heart, he also longed for such a pure and beautiful campus love, but it was a pity that he was caught by a tree early on. The tree hangs and a forest is lost.

When passing by a villa, Qin Yuanqing paused for a moment, showing nostalgia. There used to be a master of physical science living here, and he was also a senior whom he admired.

It is a pity that no matter how high the wisdom is, no matter how high the physical achievements are, in the face of the erosion of the years, people will eventually appear powerless, no match for the years, no matter how unwilling, no matter how hard they struggle.

Because time erodes not only the aging of the body, but also the decay of the soul. As people age, their thinking will become slower and slower, and eventually their thinking will stop functioning.

Many people think that as long as life technology breaks through and terminal diseases are overcome, human beings can live for a long time, but in fact, in life science research, they always face a huge difficulty or a painful thing for life scientists—— In theory, even if a person is free from illness and injury all his life and enjoys a good medical environment, he can only live to be 150 years old at most in theory.
