Rebirth of science and technology academic master - Chapter 701

c695 Visiting day (asking for monthly ticket)

That night, I don’t know how many people had a sleepless night!

The next day, Qin Yuanqing saw the members of the visiting delegation. Many of them were in low spirits, wondering if they could not sleep well in a strange environment last night.

Qin Yuanqing thought to himself.

After everyone had breakfast, they set off on the bus. Today they visited the ‘Space Station’ modular assembly center. The assembly center directly serves the ‘Double Ring Space Station’ project. Accessories from various production units are finally processed here. It is assembled and then transported directly to space via a 300-ton transport aerospace aircraft.

In the past, it needed to be carried to the Wenchang Space Launch Center by a large transport aircraft, and even the final assembly needed to be done at the Wenchang Space Launch Center. But now there is no need. After being assembled directly here, the 300-ton transport type aerospace vehicle is Planes transport people directly to space, saving countless things.

“Everyone, this is the space station assembly center. The entire assembly center covers an area of ​​10,000 acres and specializes in assembling space station modules. The center adopts the form of engineers + robots. The ratio of the number of engineers to the number of robots reaches 1:1.” Qin Yuanqing personally Serve as a commentator and introduce to everyone.

“Our ‘double-ring space station’ is constructed through modularization. The modules are transported to space one by one, and finally docked and assembled in outer space!” Qin Yuanqing is not afraid of leaks. Even if you see this kind of thing, you won’t learn it. Or you can’t learn it in a short period of time. In order to build the “Double Ring Space Station”, China spent ten years in the development phase alone. This still involved a lot of manpower, material resources, financial resources, and a strong aerospace industry.

The Russian aerospace industry obviously cannot do it. Even after the Russian aerospace industry has been upgraded and transformed, it has become the second largest aerospace industry in the world, not even comparable to the American aerospace industry. But to be honest, it is not enough, not even one-tenth of China’s aerospace industry.

What’s more, there are many technologies involved, which are not easy to overcome. Technology is useless just by looking at it. It may seem simple at first glance, but once you dive in, you will find that it is like entering a quagmire and it will be extremely difficult to move forward.

Russian experts were shocked. Whether it was modular construction or outer space docking and assembly, it was enough to shock them.

Spacecraft docking has always been a difficult point in space technology. The more components that need to be docked, the higher the risk of the entire launch process. Currently, the relatively mature docking technology in the world can only split the spacecraft into two parts and launch them to For rendezvous and docking in outer space, the docking only requires a small passage in the middle that can pass people through.

The construction of space stations in the past generations has undoubtedly been done in this way.

But the ‘Double Ring Space Station’ is obviously not that. Instead, it carries out multi-layer and multiple dockings in outer space. This technological content is simply beyond imagination.

“Your aerospace technology has reached this level. It’s really shocking!” Looking at the modules being assembled, Andre’s face was filled with complex expressions.

As the saying goes, laymen watch the excitement, while insiders watch the door.

As an aerospace expert, although he was not specifically involved, what he saw now and what Qin Yuanqing said was enough for him to understand the difficulty of this.

Andre had to admit that not to mention the final assembly of the aerospace plane he saw yesterday, but also the modular production of today’s ‘Double Ring Space Station’ project, it was far beyond the Russian aerospace industry. Many of them even thought about this kind of technology. Never thought of it.

“This is the life system we specially prepared for the ‘Double Ring Space Station’. The entire life system will greatly meet the work and living needs of the ‘Double Ring Space Station’ astronauts in the future and reduce the operating costs of the ‘Double Ring Space Station’.” Qin Yuanqing led the delegation to a special area, which is the life system of the ‘Double Ring Space Station’. This life system may seem like nothing, but in fact it contains extremely high technological content.

How to keep astronauts stationed in space for a long time is something that every space power is thinking about and exploring. After all, the cost of traveling to and from space is still quite high.

Furthermore, in this aspect, life systems are actually a necessary condition for colonizing other planets in the future. After all, within the scope of the solar system, the data that have been explored show that no matter which planet it is, there is actually no life and it is not really suitable for habitation. To be on a planet, there must be a sufficiently advanced life system to ensure the life and work needs of astronauts.

Many Russian experts looked at each other and exchanged the shock in their eyes for a moment.

To be honest, when they came to China this time, they actually didn’t have much expectations for what they could gain. After all, everyone knows that aerospace technology is a high-precision technology that is hidden by all countries, even if No matter how good of a friend you are, you won’t show it to the other person.

Unexpectedly, China would be so generous this time, taking them to see the final assembly of the aerospace plane on the first day, and even allowing them to visit the aerospace plane. Today I also showed them real things and real technology. The technology of this space station simply surpasses the International Space Station by more than ten steps.

Not only did they visit the assembly of the space station, but they also went directly to the center in the afternoon to let them see the assembly video of the space station with their own eyes. When they saw the two space modules being seamlessly connected and finally spliced ​​into the large space station, it was so exciting. This extremely sophisticated technology makes every expert’s soul tremble.

Qin Yuanqing won’t worry about whether any secrets will be leaked because of this. This kind of thing is not something you can see, nor can you try if you want to try it. For example, when the ‘Double Ring Space Station’ was not built, it showed irregular shapes. The focus is always changing. How to keep the ‘Double Ring Space Station’ running on the predetermined orbit during the construction period is a very big technical problem. China also spent a lot of energy and 10 years to solve it.

If we do not solve this problem and build such a large space station, then the construction period will appear. Because the changes in the center will cause the space station to continuously change its orbit, and even its movement will be interfered with, it will plunge into the atmosphere and crash under the gravity of the earth!

Although the Russian Space Agency and NASA have experience in building space stations in the past, they are very powerful in space technology, but it is based on experimental nature. No matter which generation of space station it is, it was still proud of overseas more than ten years ago, but in fact it is It is experimental in nature and is used to explore and explore space technology.

The ‘double-ring space station’ is, in a substantial sense, a sign that space technology has reached a certain level of maturity. It also means that it has entered the ‘space age’ and ‘aerospace age’.

If we say that before the space age, human beings were two-dimensional creatures, or at most two-and-a-half-dimensional creatures, using various tools and means to understand three-dimensionality, then the space age means that human beings have evolved from the two-dimensional, two-and-a-half-dimensional era to the three-dimensional Biology, although this kind of evolution does not happen overnight, but is a rather long process, there is no doubt that becoming a three-dimensional creature is a leap in life!

On the third and fourth days, we arranged for aerospace companies. On the third day, we went to China Aerospace Science and Technology Group, and on the fourth day, we visited private companies.

It was a good thing to go to China Aerospace Science and Technology Group. On the fourth day, we visited private enterprises. After experiencing the soul and heart shock of the first three days, the visiting group finally calmed down. Although the Aerospace Economic Corridor focused on more than 70% of China’s aerospace industry In the aviation industry, there are also large private aerospace companies with a park area of ​​30,000 acres. However, the technology is far inferior to what we saw in the past three days. Whether it is production equipment or the things produced, there is nothing to talk about. The Russian aerospace industry has these things that are ahead of its time, that is, world-class. Of course, there are also some technologies that are very groundbreaking and even eye-catching, but they don’t make people despair.

However, when summarizing the small-scale meeting held on the fourth night, the visiting team felt something was wrong the more they summarized, the private aerospace companies were comparable to the Russian aerospace industry, not only in terms of technology, but also in terms of scale, which meant that alone The aerospace industry of China’s private aerospace enterprises exceeds the strength of the Russian aerospace industry.

And they all know that in the Chinese aerospace field, private aerospace companies entered the field late and have weak foundations. They are supplementary forces in the Chinese aerospace field, not the main force. The main force is those state-owned aerospace companies, which are the ones who truly master advanced technologies.

In other words, in a sense, the technologies mastered by these Chinese private aerospace companies are all aerospace technologies that have been eliminated by the state-owned aerospace companies. The state-owned aerospace companies have no time to take into account the civilian field and support the private aerospace companies. And that’s it, the Chinese private aerospace companies The aerospace industry strength of the company exceeds that of the Russian aerospace industry!

Huge frustration!

Four cities in four days, each city has developed more than Moscow, exuding vitality, like a giant that is still growing. No one knows how powerful a warrior he will grow into.

At this time, Qin Yuanqing and Zhang Tianqin were admiring Chang’an, the Chinese city that never sleeps. Compared with before, Chang’an City was more prosperous.

“Are you really leaving?” Qin Yuanqing asked with complex emotions.

“I’m getting old. It stands to reason that I should have retired a few years ago. I just put the overall situation first and continue to shine. Now is the time to retire. Only by giving up this position to more capable and younger people can I play a better role. “Zhang Tianqin seemed very calm. He has been in this position for more than ten years and worked conscientiously. Under his leadership, China’s aerospace industry has made rapid progress and achieved a huge leap from the world’s first-class level to the world leader. China’s aerospace industry Far exceeding the combined aerospace industry of other countries, he is satisfied with this achievement.

Moreover, he is too old and is not allowed to continue working. He is over seventy years old and is no longer young. Ordinary people are already enjoying the life of having grandchildren.
