Rebirth of science and technology academic master

The higher the technical content of something, the higher the requirements for engineers, the more meticulous the pursuit of details, and there will be no mistakes.

The aerospace aircraft can almost be said to be the most advanced collection of technologies on the earth today. It is the flower of the earth's industry and the brightest pearl in the crown of the earth's industry. This is especially true.

Qin Yuanqing stayed at the aerospace aircraft manufacturing base for three days before leaving, and then came to another base. This base was specifically designed to serve the 'Double Ring Space Station', that is, the 'Double Ring Space Station' modular construction planning and design institute. Study how to modularize the construction of a 'double-ring space station'.

It is doomed to be impossible to build a big thing like the 'Double Ring Space Station' like this on the ground. Through modular construction and automated assembly, just like the 'Tiangong' space station, it is built one cabin by one and is launched into space. , and then connect the modules with each other, so as to promote the construction of the 'double-ring space station'.

Here, a special laboratory was established. The laboratory is in a weightless state to simulate space conditions. Then the R\u0026D personnel conduct module assembly through experiments one after another to determine the modularity of the 'Double Ring Space Station' and the assembly sequence to ensure The 'double-ring space station' finally realizes the designed function.

What's more, this modular construction planning and design institute can also mobilize supercomputers to conduct simulations, simulations, modeling, and tests again and again.

"Commander-in-Chief, you are welcome to inspect the work." Feng Rufeng, director of the "Double Ring Space Station" Modular Construction Planning and Design Institute, personally greeted Qin Yuanqing.

Although it is located in Tsinghua Park, the design office does not even have a signboard. The entire design office simply uses a dilapidated old building.

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

In another two years, the 'Double Ring Space Station' project will move from the research and development stage to the substantial construction stage. All other aspects are almost ready. Now the only thing missing is modularization. According to the given time limit, modular 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. Now we just have to work on the connection between the small ring and the big ring. There are always connection problems in this connection corridor. The automated connection ended in failure under supercomputer simulations." Feng Rufeng said.

All the 100 people in the design institute have been assigned orders. In the past eight years, they have all invested in modular research and development. They have overcome difficulties one by one and created technological breakthroughs one after another. In order to complete the research and development, they have We also independently developed engineering software suitable for our work.

Although there are only one hundred people in the design institute, there are eighteen universities behind them. The research and development tasks are divided and handed over to the universities to tackle key problems.

"Let's go take a look!" Qin Yuanqing was interested. According to his assumption, the modular construction and design work should go smoothly, but now it is stuck and cannot move forward.

Feng Rufeng brought Qin Yuanqing to the conference room, and then asked the technicians to open the LCD screen. The LCD screen was connected to the computer. He immediately saw the rocket transporting the modules built in various factories, into space, and came to the setting A good orbit is 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 formed at a speed discernible to the naked eye.

In the early days, modular capsules were launched into orbit through rocket launches. However, this changed in 2035, and the mode of transport aerospace aircraft was adopted to send modular capsules to space and then be spliced ​​together, just like stacking. Like a tree, the first small ring space station was finally built in 2040.

Subsequently, from 2040 to 2050, a large ring of space stations was continuously spliced ​​and formed. As a result, in the last part, there was a problem with the connection between the center cabin and the large ring!

"Commander in chief, this is the problem. We have tried various methods, but we can't solve this problem." Feng Rufeng pressed pause and pointed to a fragment of the construction of this link.

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

Qin Yuanqing pondered for a moment, looking at the enlarged part on the LCD screen, his mind began to work quickly.

For the 'Double Ring Space Station', the two slightly larger places in the middle are the energy core of the Big and Small Ring Space Station. They house the two 'Golden Crow Devices' and the required magnetic fluid generators. These two places It is the energy core of the entire 'Double Ring Space Station' and bears the energy requirements for the operation of the entire 'Double Ring Space Station'.

The other cabins at the front, back, and middle look like axes, rotation axes, but are actually experimental cabins, responsible for various experiments and scientific research tasks in space in the future. There is complete weightlessness in space.

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

Each of these ports is reserved for future connection with the aerospace aircraft.

The corridor is the channel for astronauts to go to the energy cabin and 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 astronauts for construction.

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

"Director Feng, please demonstrate this. How about building the corridor and the connection between the front and back first, and then constructing the middle?" Qin Yuanqing pointed to the place marked in red.

"Commander-in-Chief, we have tried this plan before. Yang Gong, please bring out plan No. 3 here!" Feng Rufeng said, and then asked an engineer to bring out the corresponding plan.

Qin Yuanqing saw that the video of the construction section began to change. It became connected from the two ends first, then built from the two ends to the middle, and finally connected in the middle. As a result, he encountered a new trouble, that is, the middle construction could not be completed. stand up.

Qin Yuanqing couldn't help but look thoughtful. This problem didn't occur elsewhere, so why did it appear here?

He asked someone to bring the paper and began to analyze it step by step. He saw random scrawls on the paper, like ghost drawings, with symbols marked on it.

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

But now that modular construction is being carried out, many forces or speeds that were previously negligible are now no longer possible.

Sure enough, after some calculations, Qin Yuanqing discovered that when the front and rear ends are connected, the speed is different, and the modular construction is one piece. This makes it impossible to proceed due to the different speeds and different forces when entering. construction.

In this case, it must be controlled through external force, such as a robotic arm, or astronauts to manually connect.

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

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

Qin Yuanqing next asked Feng Rufeng to simulate the robotic arm and astronaut to see how the simulation went.

"You guys should try this issue during this period, and notify me of the results as soon as possible." Qin Yuanqing said.

Although it is said that this corridor problem, even for the small ring part, will not be encountered until a few years later, these discovered problems must be solved during the development stage, 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 an altitude of about 400 kilometers from the ground, under the conditions of the space environment, it is destined to encounter various problems during construction, and these problems They all need to rely on the wisdom of engineers to solve them.

Qin Yuanqing never thought that if there was no problem in theory or with supercomputer calculations, then there would really be no problem in actual construction. That would be too naive.

"Okay, I'll notify you as soon as there are results!" Feng Rufeng nodded.

Then, the person in charge of this part was asked to start working on the plan. These people were engaged in this job. Their superficial identity was to be researchers at the university. Even to their relatives, they said they were doing research at Shuimu University. As for What kind of research are you doing? Sorry, I can’t tell you, and you can’t ask.

Everyone knows that Shuimu University is involved in a lot of confidential research, so their families can understand it more.

Leaving the 'Double Ring Space Station' Modular Construction Design Institute, Qin Yuanqing was walking 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 outstanding students. Most of the scientific research institutions have moved to the Shahe campus.

Walking on the path of Tsinghua Garden, Qin Yuanqing looked at the boys and girls holding hands and chatting in low voices, and couldn't help but show envy. In his heart, he also longed for such a pure and beautiful campus love, but unfortunately he was killed by a tree early. The tree hanged and a forest was lost.

When passing by a villa, Qin Yuanqing paused for a moment, showing a nostalgic look. A great master of physical science once lived here, and he was also a senior he admired.

It's 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 time, people will eventually become powerless and unable to defeat the years. No matter how unwilling they are, it will be useless 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 running.

Many people think that as long as there are breakthroughs in life technology and terminal diseases are overcome, humans can live for a long time. However, in fact, in life science research, we are always faced with a huge difficulty or something that makes life scientists painful - Theoretically, even if a person has no illness or injury throughout his life and enjoys a good medical environment, he can theoretically only live to be 150 years old at most.
