Chapter 246 Urgent

"Of course, the solution just mentioned, like Musk's Starship, which reduces the cost to less than $10 per kilogram, is an ideal solution.

If its carrying capacity needs to reach about 5 tons, the requirements for the plasma engine will be very high.

During the starting phase, huge amounts of electrical energy need to be consumed and released quickly in a short period of time, generating a large amount of reaction force to allow the rocket to escape the earth's gravity.

The launch we are about to do soon is more of a pre-research level.

In the short term, we will still have to rely on electromagnetic launch, mainly using ultra-high-speed superconducting suspension and electromagnetic propulsion to boost the rocket to above supersonic speed on the ground and then ignite and take off.

After escaping the Earth's gravity, it will be propelled by the plasma engine. The whole system is a three-stage power system." Chen Yuanguang said.

After the project was approved, Chen Yuanguang felt that in order to reduce the overall dependence on chemical fuels and reduce the complexity of fossil fuel engines, it would be possible to continue to use plasma engines with greater thrust at the end. The plasma engine also uses room-temperature superconductors to build its internal magnets.

"I want to watch the sun rise in the east and the sun set in the west with you @光甲航空"

"I want to watch the Gobi Desert and the smoke in the desert with you @China Aerospace"

To be honest, under the influence of the strong culture of the past in the West, the Chinese Valentine's Day actually has little presence, and its presence is even weaker than the concept created by consumerism - 520.
In recent years, as feminism has been treated as a serious topic by men, the Chinese Valentine's Day has become even less noticeable. No matter how the major e-commerce platforms deceive people, male consumers just won't be fooled.

It was the same on this day. Netizens originally thought it was just an ordinary Chinese Valentine's Day, but they didn't expect that the official Weibo of Guangjia Aerospace and the official Weibo of China Aerospace interacted with each other.

The interaction is quite ambiguous, with a bit of Chinese Valentine's Day copywriting in mind.

But whether it is the lonely smoke in the desert or the sunrise in the east, it fills the imagination of Chinese space enthusiasts:
"Could it be that the "In My Lifetime" series is finally going to appear? I will be able to see the cooperation between China Aerospace and Light Armor Aerospace with my own eyes?"

"I don't know what big project it is. You know, before, Guangjia Aerospace helped Huaguo Aerospace to send human hibernation equipment to the Tiangong, and neither side did it so disgustingly."

"Fuck, this is such a good secret. I've never heard any news before."

"What's going on? What's going on? Urgent, urgent, urgent, urgent, the king is me."

"Can you please stop being a riddle teller? I'm curious about any breakthroughs you've made."

"I thought you two had never seen each other again."

"Can you tell me what the surprise is?"

The post was published on Weibo at exactly 9 a.m., and five minutes later it was on the top of Weibo's hot search list.

Because of technological breakthroughs, China's life now is much better than it was in 20-22. Even if Europe imposes tariffs on China's automobile industry in order to protect its own industries, they cannot impose tariffs on the photovoltaic industry.

Because the tariffs they impose on China's photovoltaic industry will be transferred as costs to their own domestic companies.

Another breakthrough is the chip industry. The two pillar industries have effectively alleviated China's internal economic situation. All 4V outer islands were conquered without any actual interference. This has given China the confidence to sit at the table and watch its competitors take turns to perform.

The overall environment has improved unprecedentedly, and even America's financial pillars are being dismantled one by one.

The public opinion field is dominated by rabbits, and the gods can only make a few sarcastic remarks in secret.

Thanks to the success of Musk's Starship, the aerospace field is one of the few areas that the gods can hold their heads high.

Now that Guangjia Aerospace and Huaguo Aerospace seem to be joining forces to cause trouble, the gods are very panicked, fearing that they will lose another weapon in the struggle of public opinion.

At noon, the 30-minute news program of China Central Television dealt a heavy blow to the gods.

"On August 8, according to official news from China Aerospace Science and Industry Corporation, the Shenzhou-Guangjia electric rocket jointly built by China Aerospace Group and Guangjia Aerospace Group was successfully launched today. The rocket is a pure electric rocket based on electromagnetic launch superconducting technology and plasma engine technology, and will be used to launch small satellites in the future.

It is reported that the success of this test marks a major breakthrough in the application of room-temperature superconducting technology in the field of rocket launches. According to official news from China Aerospace and Guangjia Aerospace, a composite-powered recyclable rocket built on the same technical framework will be launched by the end of this year at the latest. After the successful launch, it is expected that the cost of rocket launches will be greatly reduced. "

After the host's introduction, there was a brief interview with the person in charge of the entire project's Chinese aerospace department.

After the program was broadcast, various official accounts simultaneously expressed their opinions on Weibo.

Everyone can only vaguely see from the video that the huge launch tower is different from the red and yellow lights during other rocket launches. There is no light during the entire rocket launch. It is directly electromagnetically driven and the rocket disappears into the sky in a flash.

"Shenzhou-Guangjia rocket launched successfully" quickly topped the Weibo hot search list.

This matter is being discussed on various platforms including Weibo, Zhihu, and Douyin.

“I can only say that I have only heard of milk tea and coffee blind boxes being co-branded in the past, and this is the first time I know of a rocket launch being co-branded.

I would like to ask Huaguo Aerospace or Guangjia Aerospace, can you include our company in the next joint venture? Any amount of sponsorship is fine." A senior executive of a major mobile phone manufacturer said on Weibo.

Lei Jun took it seriously after seeing it. He thought that with his personal relationship with Chen Yuanguang, it was not impossible for him to make a light mech - Xiaomi. It would not be too much to ask Xiaomi to be responsible for installing air conditioning in the space station, right?

“Thank you for the invitation. Room-temperature superconductivity is indeed the holy grail of physics. In the past, there has always been a voice in the market saying that room-temperature superconductivity is not that amazing and has not changed our lives.

This kind of speech is most common among certain Runren groups. In short, as long as the technology is a breakthrough made by China, it is not important. The technology that China has not mastered is the jewel in the crown of human technology. The only regret is that there don't seem to be many jewels in the crown.

Back to room-temperature superconductivity, at the beginning of this year, Malaysia's Alpha Technology taught the world a lesson by using room-temperature superconducting technology to build a quantum computer.

If you attribute that to the fact that quantum computers are powerful, then why can't the Americans build quantum computers of this level? Isn't it because the basic materials have a limit?
Of course you can say it is not because of room-temperature superconductivity, but this time it must be because of room-temperature superconductivity, right?

The rocket launch broadcasted in the official video this time is different from all the rocket launch scenes we have seen before. There is no fuel burning. I remember clearly that the host introduced two types of rockets in the 30-minute news, one pure electric and one hybrid. This time it is a small pure electric rocket.

As we all know, rockets use speed to escape the gravitational pull of the earth. All previous rockets that left the earth used fossil fuels, which used the high-temperature and high-speed jets produced by fuel combustion to generate a strong reaction force, which continuously accelerated and lifted it up until it flew out of the atmosphere.

So we see the light produced by the huge burn during the rocket launch.

However, existing rockets basically take off directly from ground launch pads, and in order to accelerate and fly away from the troposphere with dense air and high resistance, a large amount of fuel is needed.

In the past, in order to reduce losses, there have been various plans, including launching rockets from aircraft to the air, launching rockets from balloons to high altitudes, launching rockets from centrifuges, and so on.

Like the Pegasus air-launched rocket of America in 1990, it was suspended under the belly of a passenger plane before launch. When the plane climbed to an altitude of about 13000 meters and flew at Mach 0.8, the rocket was released, and then the first-stage solid engine was ignited to accelerate the climb.

These launch methods all have drawbacks, especially using an aircraft as a launch platform. Its operation and maintenance costs are not low, its transportation capacity is limited, and it can generally only launch small rockets, with insufficient capacity to enter orbit.

That is the so-called high cost. Of course, the Shenzhou-Guangjia launched this time should also be a small rocket, but its advantage is that the operating cost of the ground launch pad is much lower. Considering the use of room-temperature superconducting materials, the overall energy requirements will also be much lower.

After reading it, I only have one feeling, that is, the Americans will not be able to sleep. The overall cost reduction, coupled with the room-temperature superconducting electromagnetic launch platform, will make China's supersonic missiles faster and more difficult to intercept, and the launch cost lower? I can think of it, how can the Americans not think of it?

Supersonic missiles are difficult to intercept in themselves, so won’t this be even more difficult to intercept?
As well as the possible electromagnetic guns in the future, room-temperature superconducting technology is enough to make the Americans feel uneasy.

As for the composite-powered rocket mentioned in the news, the achievable cost has been greatly reduced as advertised. All I can say is wait for the official news.

It depends on whether the Chinese proposal has lower costs or the Starship proposal proposed by Musk has lower costs.

Now, room temperature superconducting technology is the Holy Grail. Let's use the words of Run people, fortunately the technology is in the hands of civilization. If the United States can achieve a technological breakthrough, I dare not imagine what the consequences will be. The United States should just honestly master civilized technology such as GPT. "

“Thank you for the invitation. As an industry insider, this project is kept secret. I hadn’t heard any news about it before it was successful.

I asked many colleagues, and no one had heard any rumors about it. It was as if it suddenly appeared out of nowhere.

Having said that, it is a very normal thing for China's aerospace industry to engage in superconducting electromagnetic launch.

Long before the birth of room-temperature superconductivity, whether it is officially announced or what I know, China's aerospace industry has been conducting research on superconducting electromagnetic launch systems.

It’s just that we are doing research first to see the effect and support this team so that if there is a breakthrough in superconducting technology, we can quickly enter the formal research and development stage.

Even before the advent of room-temperature superconductivity, the Third Academy of China Aerospace Science and Industry Corporation conducted an electromagnetic launch high-temperature superconducting electric suspension navigation test, achieving a test speed of 380 kilometers per hour on a 234-meter line.

After the birth of room-temperature superconductivity, even a one-dimensional room-temperature superconductor can be directly used in this electromagnetic emission system.

From the video, we can see that China Aerospace and Guangjia Aerospace are building a magnetic levitation train track perpendicular to the ground based on room-temperature superconductivity.

On the launch tower, the suspension coil is responsible for maintaining the launch direction of the rocket and preventing the rocket from generating resistance due to friction with the track. The acceleration coil provides the rocket with powerful takeoff thrust, helping it to get out of the dense air near the ground as quickly as possible.

After the rocket is fully accelerated by the launch device and breaks out of the troposphere, the first-stage engine is ignited, continuing to accelerate and climb, and finally entering orbit.

Because room-temperature superconducting materials do not require a cooling system, the entire launch device can be made very large and can be used repeatedly.

In addition, the Shenzhou-Guangjia is a pure electric rocket that uses no fossil fuels, so its structure can be made very simple and very light.

I can only say it's awesome, and I can roughly guess the technical details inside.

Compared to this public rocket, I am more curious about how the composite-powered rocket is designed.

I don’t know whether the entire project is led by Guangshen or China Aerospace. I just hope that there will be more revelations after it succeeds.

But no matter what, I think that the technical framework built by China Aerospace and Guangjia Aerospace based on room-temperature superconducting technology will be the most imaginative rocket series in history.

This system can be said to have completely overturned the past fossil fuel rocket system: oxidizer-fuel-engine. The oxidizer and fuel are gone, and there is only the engine and electric energy to drive it. This is a huge breakthrough in the aerospace field. I have a hunch that I will really see the arrival of the era of commercial aerospace in my lifetime.

What I am looking forward to is a future where there is no electromagnetic drive and the rocket is pure electric. It depends on when the energy density can be broken through. "

The technological breakthroughs in China's aerospace field have caused a sensation not only in China, but also around the world.

For foreigners, due to the large-scale export of China's new energy vehicles, China's presence in their daily lives can be said to be getting higher and higher, and the news related to China has also changed from negative to relatively objective and then to relatively positive now.

At least outside of traditional American forces, public opinion is becoming increasingly friendly toward China.

The number of views of a certain YouTube video quickly exceeded 100 million, and most of the comments below were congratulations, while a few were sarcastic.

"Congratulations to China for achieving a breakthrough in aerospace technology."

"I am increasingly convinced that China will take us to Mars, not Musk"

"America should ban India from joining the International Space Station program because it means our technological progress will be accelerated"

"When China said, 'Okay, let's do it ourselves and do it better,' America just said, 'Wait, that's not the goal,' and China hit back with 'It's too late.'"

"I've always seen Westerners on YouTube saying that China didn't develop its own technology, they stole it from us, and they try to take credit for China's technological advancement. It's interesting, and even more interesting is that I'm curious if anyone will say that China stole the electric rocket this time? I mean how can China steal something that you don't even have."

"Wright is the best scientist of the 21st century. He single-handedly led China's scientific and technological progress. It has to be said that India's biggest dilemma at present is the lack of its own Wright."
