Rebirth of science and technology academic master

The 'Tiangong' space station is China's own space station built through its own efforts. It carries more of China's exploration and experiments in space station construction. In a sense, the 'Tiangong' space station is It is an experimental transitional product.

This can be seen from the fact that the structure and operation design life of the Tiangong space station is only 10 years.

The 'Tiangong' space station consists of the core module 'Tianhe', the experimental module I 'Wentian' experimental module, the experimental module II 'Mengtian' experimental module, the cargo spacecraft 'Tianzhou' cargo spacecraft, The manned spacecraft "Shenzhou" consists of five major parts.

The Tiangong space station has a design life of 10 years and a scale of 80 tons. After each group of astronauts is stationed for 6 months, it will rotate with the next group of astronauts to complete the continuous space resident mission. Each group of astronauts has 3 people. .

Precisely because China has never built a space station and has no experience, the Tiangong space station is actually an experimental space station and a transitional space station.

It can only meet China's short-term aerospace needs, but cannot meet China's long-term aerospace needs. Ten years later, when the design and operation period is up, it can basically be declared that the Tiangong space station will be decommissioned.

Because ten years from now, even if we go by current common sense, we know that the Tiangong space station will no longer be able to meet China’s development needs ten years from now.

Qin Yuanqing used his laptop to create a space station that he thought would be 10 years from now. The person who has the best grasp of what China will look like 10 years from now is Qin Yuanqing. After all, only Qin Yuanqing knows about many confidential scientific research tasks.

As for some things that Qin Yuanqing will promote in the next few years, only Qin Yuanqing knows in his heart, and others do not know at all.

Unconsciously, the meeting reached the third day. Qin Yuanqing felt that he had to stand up and say something. Otherwise, if the discussion continues today, a consensus and meeting minutes will be formed to determine the research and development direction of the next generation space station. In that case, there will be consequences. A lot of unnecessary waste.

"Comrades, everyone's positive speeches in the past two days are very good. It shows me everyone's confidence in the development of China's aerospace industry!" Qin Yuanqing was the first to speak at the beginning of the morning meeting. The conference room was silent, and everyone was speechless. Looking at Qin Yuanqing sitting in the front, many people had surprise in their eyes.

You must know that Qin Yuanqing said nothing in the past two days. Everyone thought that Qin Yuanqing recognized their thoughts and opinions, or that Qin Yuanqing's energy was not in aerospace and he did not want to speak more.

Unexpectedly, Qin Yuanqing immediately spoke at the beginning of the meeting on the third day.

Although Qin Yuanqing rarely appears in the aerospace field, no one will underestimate Qin Yuanqing. They are very aware of Qin Yuanqing's influence. After all, Shuimu's aerospace-related majors are among the top three in the country.

Qin Yuanqing focused everyone's attention on himself, and then asked the staff to connect the projector cable to his computer. On the huge screen at the front, as Qin Yuanqing opened the model, he suddenly saw a giant disk-shaped space station full of science fiction. .

This disc-shaped giant space station has a smaller disc on the upper part and a larger disc on the lower part. In the middle of the two discs are shaped cabins, and the space between the cabins and the discs is formed by a shaft.

Everyone looked at the giant disk space station full of science fiction on the screen, their mouths opened, and their eyes were full of disbelief.

Is it possible that Qin Yuanqing has watched too many science fiction movies or science fiction novels and dared to come up with such a space station that only exists in science fiction movies and science fiction novels? How could such a space station be built by China in ten years or one hundred years? After that, China can't build it either!

"Everyone, take a look at the next-generation space station I have built in the past two days. I named this space station the 'Double Ring Space Station'. The upper disk has a radius of 500 meters and the lower full radius is 1,000 meters. The upper and lower disks are the living area. , command area and material area, artificial gravity is formed through perfect rotation, allowing astronauts to be stationed on the space station for a long time without 'space motion sickness'. Each node in these areas is equipped with anti-gravity devices, which will be used for future launches. It is launched using anti-gravity technology and is also used as a docking place for the space shuttle and the space station. These places are communication devices for communication with the earth and satellites!"

“In the middle of the double ring are two experimental cabins and a power plant. Each experimental cabin can meet a large number of experimental needs. The living cabin, command area, and material area are connected through these rods, and the experimental cabin can be entered for space experiments. The two power units in the middle are two controllable nuclear fusion reactors. These two controllable nuclear fusion reactors will provide a steady stream of energy for the 'Double Ring Space Station' and meet all aspects of the 'Double Ring Space Station'! "

Qin Yuanqing continued: "The optimal perigee of the 'Double Ring Space Station' is 398.8 kilometers, and the apogee is 428.6 kilometers. It takes 90 minutes to orbit the earth, and the orbital inclination is 51.8 degrees. The 'Double Ring Space Station' and the investment of 3 trillion yuan can be divided into two parts. During the first phase of the project, as well as the first ring project and the second ring project, the service life of the 'Double Ring Space Station' is designed to be 30 to 50 years!"

Qin Yuanqing continued to talk about his thoughts and assumptions, while others were numb after listening to it, whether it was the 'double-ring space station' full of science fiction, its large scale, high construction difficulty, or large investment , It simply hammered their souls and hearts hard.

It is estimated that such a ‘double-ring space station’ will not be built for ten consecutive years. What's more, the technical difficulties involved are simply massive. Whether it's special materials that can resist space radiation, controllable nuclear fusion, or anti-gravity technology, just thinking about it will make people feel numb and helpless. .

There is also the terrifying investment, which is 3 trillion yuan at the beginning. You must know that the investment in the Tiangong space station is 60 billion yuan, totaling more than 10 billion US dollars. The huge investment in the Tiangong space station is even less than a fraction of the "Double Ring Space Station".

And even the International Space Station took more than 10 years to complete and cost approximately US$100 billion, which is already terrifying. The ‘Space Mushroom’ space station proposed by the United Space Block Structure Company currently requires an investment of US$300 billion, which is approximately RMB 1.77 trillion, which is almost half of the ‘Double Ring Space Station’.

Considering the actual purchasing power of the two, the difference is at least five to six times.

Thinking about such a large investment makes people's scalp numb. It is impossible to invest such a large amount of money in this 'double-ring space station'.

Qin Yuanqing's introduction lasted all morning.

By the time it was lunch time, all the technical experts in the conference room had stiff and numb faces, obviously they had not yet recovered from the shock.

Qin Yuanqing sighed, could the situation be bigger? Why do you always want to make small troubles, and why don't you want to make a big trick?

Sure enough, even though he was at a high place, he clearly proposed a space station plan that was reasonable, feasible and capable of meeting future development. However, others simply didn't understand, didn't understand, and didn't even understand. They even thought he was crazy.

"Xiao Ma, do you think Academician Qin is crazy? How could he come up with such an outrageous plan? Doesn't he know that science fiction novels and science fiction movies are illusory and fake? Illusion is illusory, but reality is real. , Such a space station will not be built in 10, 20, or even 100 years!" A very smart middle-aged man felt that the food in his hand was no longer delicious, and muttered to his friend.

"Niu Niu, I also think Academician Qin is crazy. He must have been studying some theory recently and has gone crazy. But I have to say that the 'Double Ring Space Station' model he made is really full of science fiction beauty! This one has it Ability, he can get very good without engaging in education or scientific research." Xiao Ma said to his friend 'Niu Benben'.

Xiao Ma, named Ma Donglai, graduated from Beihang University and was a classmate of Niu Benben. After graduation, they also engaged in the aerospace industry.

"This 'Double Ring Space Station' is probably not built by humans. Only gods can build it." When Niu Benben said this, he lowered his voice: "You said whether Academician Qin is studying theology recently? They all say it's scientific. The end is theology. Could it be that Qin, Yuan and Qing made the same mistake as Newton?"

As the backbone of China's aerospace industry today, Ma Donglai and Niu Benben actually know China's aerospace technology very well. It is currently ranked at the world's leading level and belongs to the first echelon in the world. That is, landing on the moon, which is theoretically no longer possible. The problem is that it is technically feasible.

Chang'e 5 landed on the moon, returned to the earth, and brought back a large amount of lunar soil. In the same way, people can naturally be sent to the moon and then returned to the earth from the moon.

But they believe that even after another ten years of development, it is impossible to have the ability to build a ‘double-ring space station’.

For example, controllable nuclear fusion. For this technology alone, even if they are not in this field, they know that controllable nuclear fusion technology has always been hailed as "forever fifty years". No one knows when controllable nuclear fusion will be achieved. technology.

For example, anti-gravity is a concept that only exists in science fiction novels and science fiction movies. In theory, no one has created the relevant theories and basis for anti-gravity. However, artificial gravity is relatively reliable.

Not to mention that they want to move quantum computers to the "Double Ring Space Station", and everyone uses quantum computers for office work.

Of course, those engaged in aerospace engineering know very well that space is actually not safe. There are countless space debris, space junk, and extraterrestrial meteorites, not to mention the ever-present ultraviolet rays that corrode steel or materials, reducing the life of the space station. It won't last long, so Qin Yuanqing casually mentioned that the service life of the space station is 30 to 50 years. This is not a rant!

Qin Cannon! ?

The two people couldn't help but think of the nicknames given to Qin Yuanqing in the early years. They understood why some people called Qin Yuanqing 'Qin Cannon' in the past.

This is simply less reliable than the cannons of the Republic of China.
