Great Country Academician

Chapter 994 The difficulty of making nine stars~

After carefully flipping through the documents in his hand, Xu Chuan placed them on the coffee table.

Opposite me, Academician Chang Huaxiang asked with a smile: "How do you feel?"

After thinking for a while, Xu Chuan said: "Theoretically, it is indeed feasible, but it is extremely difficult to build such a huge space carrier."

"Sending a giant circular object with a diameter of more than 500 meters into space at one time is impossible even with our current aerospace technology."

"A relatively reasonable approach is to transport it to space in sections and dock it in orbit. However, ensuring that large parts with large arcs are accurately docked in space will be a severe test for technology, craftsmanship and operational experience.

"Even if this is the case, we can produce parts on earth, assemble them into semi-finished modules and launch them into space. I am afraid it will take at least 5-8 years, or even 10 years to do it."

"and"

After a pause, he looked at the documents on the table and continued with a slight frown: "In addition to the difficulty in design and construction, such a huge object is running in space."

"Even in low-Earth orbit, the space electrodynamic problems caused by the rotation of its outer ring structure cannot be ignored."

"This is the same as the 'space elevator' project we talked about before. The steel rope flying around the earth's magnetic field will also produce electromagnetic phenomena."

"Whether it is a steel cable or the outer ring structure of the space carrier, as a conductor, when flying in the earth's magnetic field at the first cosmic speed, cutting the magnetic field lines will generate higher voltage, which is one of the potential dangers."

"On the other hand, from a physical point of view, this type of large rotating spacecraft will inevitably encounter the problem of center of gravity shifting."

"To put it simply, when a large mass object moves in the pipe, maybe a few people or heavy equipment, the entire space station will inevitably start to sway under the action of centrifugal force."

"It's also a big problem for the people living inside and the equipment deployed."

"In addition, although the diameter of this space carrier is an astonishing 520 meters in design, its diameter is still too small for a gravity simulation device."

"This results in a different 'gravity' between the person's head and feet, and the gravity gradient can produce a certain degree of dizziness."

".These are foreseeable problems for this space carrier."

Although I am not a professional in the aerospace field, I have been developing new space shuttles for so long, and I have also come into contact with and learned a lot of professional knowledge in aerospace.

Although he is not as good as Academician Chang Huaxiang, he can still do it if he just gives some of his own ideas and suggestions for the design of this space carrier.

Of course, compared to professionals, his knowledge is nothing.

I believe that since the Aerospace Group has given a complete design plan for the space carrier, these issues he raised must have been considered.

Although it is said that it is nine stars difficult to build such a space carrier, with China's current economic strength and aerospace technology, this is not completely impossible.

But a 500-meter-long space carrier, even if it takes ten years, is completely worth it to the country as long as it can be manufactured.

An aerospace carrier that permanently cruises in outer space and low-Earth orbit will become another overlord after the aircraft carrier, replacing the aircraft carrier and becoming the protagonist of future wars.

Of course, with the current development speed of science and technology in various countries, in Xu Chuan's view, even if the construction of this space carrier is completed, it is more likely to carry out 'immigration', 'material transportation' and 'space development' between the Earth and Mars. 'Wait for functions.

After all, no country except China can freely enter and exit space.

Although the United States has decades of leadership in aerospace technology, it has also restarted space shuttle technology.

But really speaking, compared to their space shuttle, Lao Mi lags behind by more than a star.

The core basis of the new space shuttle is the miniaturized controllable nuclear fusion reactor and aerospace engine.

As for the former, let alone miniaturization, even large-scale controllable nuclear fusion has not been achieved yet.

Not to mention the aerospace engine, which is an epoch-making product developed based on room-temperature superconducting materials.

These two most core basic conditions, just pick one of them, is enough for Lao Mi to catch up for 20 to 30 years or even longer.

As for the space shuttle they restarted, the so-called 'Endurance', in fact it was just continuing to rest on its laurels.

Not only are they resting on their laurels, but it can even be said that they have regressed a lot compared to their peak space shuttle technology in the last century.

You know, at the peak of the space race in the last century, the United States owned the Saturn V super-heavy rocket and seven large space shuttles.

Not only did it carry out many manned missions to the moon, it also accelerated the disintegration of Hongsu.

But now, the aerospace strength currently displayed by the United States is far inferior to what it used to be.

Even if SpaceX held up the sky half a century later, it used the BRF Heavy Falcon rocket to tell the world that they were still capable of sending astronauts to the moon.

But what everyone in the world sees is that the United States has long lost its dominant position and capabilities in the aerospace field.

Instead, it is China!

In the 21st century, they not only achieved manned lunar landing, but also built a huge outpost scientific research base on the moon.

At the same time, China also led and promoted the world's largest outer space cooperation project, the "Lunar Biosphere Project"!

More than 30 countries in the world participated, with a total investment of 200 billion RMB!

If calculated according to the current exchange rate, its total investment reached an astonishing 50 billion US dollars.

However, in 2025, in international trade, the most widely used transaction currency in various countries is no longer the US dollar, but the RMB they issue.

In the past, the US dollar foreign exchange that countries have been constantly reserving is also being replaced step by step with their RMB reserves.

In contrast to the US dollar, RMB currently has no anchor.

Or to put it another way, if the US dollar is anchored to oil, then the RMB's anchor is China's full industrial chain industrial system.

They will not follow the way the United States uses the US dollar to harvest the world and use force to maintain their currency status.

The most ideal way is to anchor the entire industrial chain of China through currency, use the reputation and stable strength of the world factory, and the ability of RMB to fight against global financial risks as endorsement, so as to enhance the international status of RMB.

This is the most reliable and trusted way.

In other words, the anchoring method of RMB is that as long as you hold the currency of China, you can buy any bulk product.

China's biggest advantage now and in the future is industry!

Huge industry, huge modern industry, information industry, and the intelligent industry that is currently developing, smart industry and future space industry, etc.

Only industry is the basic resource that truly supports the development of science and technology.

The deindustrialization of Lao Mi, instead of using finance to control the world, playing the game of passing the parcel, everyone is not stupid, but just can't resist at the beginning.

Borrow money every day, the economy is not good, pull a wave of interest to let the US dollar flow back, pull up the exchange rate of small and medium-sized countries, and then buy at a low price.

This trick has been tried and tested in the past few decades.

And now, someone who can break this pattern has appeared.

More importantly, this new model of anchoring industrialization is still beneficial to everyone. When the pattern changes, there will inevitably be countries that quickly follow up and replace currencies. Why not?

For them, the large-scale flow of RMB to the world, replacing the rice and yuan as the mainstream trading currency, is also a hundred benefits without any harm.

When they become the mainstream trading currency, they can not only greatly enhance China's international influence in the world, but also reduce exchange rate risks and transaction costs, promote economic structure optimization, promote the development of the financial industry, etc., and the advantages are also full.

After chatting about the aerospace mothership for a while, Academician Chang Huaxiang seemed to remember something, looked up and asked curiously.

"By the way, I remember that you were studying the electromagnetic shield technology before? How is it now? Is there a chance to apply it to this aerospace mothership?"

Although he has been in charge of the work at the Xiashu Aerospace Base, he still knows about the research and development of electromagnetic deflection shield technology.

Because this technology was designed by Xu Chuan for large-scale deep space navigation from the beginning, this is also what Director Wu Yuankang of the Space Administration is more concerned about.

This time, Director Wu came and consulted him about this work.

However, the department responsible for research and development is not the Space Research Institute and Xiashu Base, but the other two departments of Xinghai Research Institute.

Of course, the Space Research Institute is also involved, but the main force is still the group of people who studied controlled nuclear fusion technology at the beginning.

After all, if you want to say which organization in the world is the most powerful in the control of plasma and magnetic field, it has to be Xinghai Research Institute, which has solved the problem of high-temperature plasma turbulence.

Most of the personnel of the Space Research Institute were later transferred or poached from other space agencies, and their research in this area is not in-depth.

Even the aerospace engine, although nominally a project of the Space Research Institute, is actually led by the Energy Research Institute.

Hearing this question, Xu Chuan thought for a while and replied: "It has been completed in part, and there is a phased result, but it is still a long way to go before it can be applied to aircraft such as aerospace carriers."

"As for when it can be solved, no one can say for sure. It depends on when the remaining plasma shield modules can make a breakthrough."

The technology of the magnetic polariton electromagnetic shield generator in the electromagnetic deflection shield has indeed made a significant breakthrough. By applying technologies such as magnetic polaritons and explosive magnetic compression, the shield completed based on the polariton theory of the strong electron-phonon interaction system and the strong electric unified theory can already intercept high-power microwave attacks.

To say that it is valuable, it is definitely there. Even if it is a phased result, its integrity is not bad and has extremely high application value. Other countries cannot do it in the research and discovery stage.

Before, he heard from the people at the Navy Equipment Department that they wanted to apply the magnetic polariton electromagnetic shield generator to the Haixi aircraft carrier, but later they gave up for a short time.

The reason is very simple. The communication problem cannot be solved.

If they are on the ground, and they are generating electromagnetic shields for a scientific research institution or ground unit, they can also set up a communication network underground to transmit signals and information through wired means.

But on mobile devices such as aircraft carriers and aerospace carriers, wireless communication is the only way to exchange signals with the outside world.

The electromagnetic shield generated by the magnetic polariton electromagnetic shield generator shields electromagnetic signals in all channels.

This means that when the shield is turned on, not only the outside world cannot detect it through electromagnetic waves or attack it through high-power microwaves. The equipment protected inside cannot transmit signals to the outside world.

This is a fatal flaw for aircraft carriers that need to carry carrier-based aircraft and serve as overseas mobile command centers.

After all, the shields need to be turned on often in wartime.

And the lack of aircraft carrier signals in wartime can have predictable consequences.

At that time, the carrier-based aircraft will not receive the guidance signals for takeoff and landing, and will plunge directly into the vast ocean, which will be fun.

Therefore, the current application areas of the magnetic polaritons and electromagnetic shield generators are still quite limited. When other wireless communication technologies other than "electromagnetic waves" can be used, the electromagnetic shield generator will be widely used.

As for now, it is just to protect the "privacy" buildings or equipment on the ground.

However, judging from the current situation, the upper level is very satisfied with the electromagnetic shield technology.

After shielding the electromagnetic waves, it means that unless the most primitive optical exploration equipment is used, other electromagnetic wave imaging systems will be a mess for the protected area.

This technology has been used to keep some secret military areas confidential, and it has initially achieved excellent results.

Academician Chang Huaxiang nodded, and did not continue to ask further questions. He smiled and put away the report documents on the coffee table and spoke.

"That's all for today. I'll find a few trustworthy people at the Aerospace Research Institute and Xiashu Base to study this report on the aerospace carrier."

"I'll submit it to the Space Administration based on your opinions and ideas."

Xu Chuan nodded with a smile and said, "Then I'll trouble you, Mr. Chang. The higher-ups have been wanting to do this for a long time. We'll help as much as we can."

Chang Huaxiang said cheerfully, "Well, don't worry. If it's really built, it'll be good news for us."

Whether it's national defense strategic deterrence or the development of Mars, such a large aerospace carrier is indeed very useful.
