Chapter 246 Urgent Urgent
“Of course, the plan just mentioned is the same as Musk’s starship that reduces the cost to less than 10 US dollars per kilogram. It is an ideal plan.
< br>If its carrying capacity needs to reach about 5 tons, the requirements for the plasma engine are very high.
In the initial stage, it needs to consume a huge amount of electrical energy and release it quickly in a short time, generating a large amount of reaction force. The rocket escapes the gravity of the Earth.
The launch we are going 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 levitation and electromagnetic propulsion to boost the rocket above supersonic speed on the ground before igniting and taking off.
After it escapes from the gravity of the earth, it is then driven by a plasma engine. The whole is a three-stage power system. "Chen Yuanguang said.
After the project was established, Chen Yuanguang felt that in order to reduce the overall dependence on chemical fuels and reduce the complexity of fossil fuel engines, a plasma engine with greater thrust could be used at the end. Plasma engines The internal magnet is also made of normal-temperature superconductors.
“I want to watch the sunrise in the east and the sunset in the west with you @Guangjia Aerospace”
“I want to watch the Gobi Desert with you. Desert Smoke@Huaguo Aerospace”
To be honest, under the influence of Western strong culture in the past, the Chinese Valentine's Day actually has no sense of existence. The sense of existence is not as thin as a concept created by consumerism -520.
In recent years, with the rise of women's rights, men have regarded it as a After treating the topic seriously, the Chinese Valentine's Day has no sense of existence anymore. It is still deceived by major e-commerce platforms, but male consumers just don't fall for it.
It was the same day. Netizens originally thought it was just an ordinary Chinese Valentine's Day, but unexpectedly, the official blog of Guangjia Aerospace interacted with the official blog of Huaguo Aerospace.
The interaction is quite ambiguous, a bit like Chinese Valentine’s Day copywriting.
But whether it is the solitary smoke in the desert or the sun rising in the east, Chinese aerospace enthusiasts are full of daydreams:
"Is it possible that the series will finally appear in my lifetime? Can I see with my own eyes the cooperation between Huaguo Aerospace and Guangjia Aerospace?"
"I don’t know what big project it is. You must know that Guangjia Aerospace helped Huaguo Aerospace to transform the human body The hibernation equipment was sent to the Heavenly Palace, and neither party was so stupid.”
“Damn, this is a very good job of keeping it secret. I’ve never heard anything about it before.”
"What's going on, what's going on? Urgent, emergency, emergency, the king is me"
"Can you stop being the Riddler? I'm curious about any breakthroughs"
"I thought you two never interacted with each other."
"Can you tell me what the surprise is?"
I posted it on Weibo at nine o'clock in the morning, and it was blocked five minutes later. It topped the Weibo hot search list.
Because of technological breakthroughs, China's life is much better now than in the years of 20-22. Even if Europe is crazy to increase tariffs on China's automobile industry in order to protect its own industry, they can never impose The photovoltaic industry will increase tariffs.
Because the tariffs they impose on China's photovoltaic industry will turn into costs and be transferred to their domestic companies.
In addition, there is a breakthrough in the chip industry. The two pillar industries have effectively alleviated China's internal economic situation. They have conquered all 4v outer islands without any actual interference. This has given China the confidence to sit at the poker table and watch the competition. The opponents took turns singing.
The overall environment has improved unprecedentedly, and even Amerikan’s financial pillars are being dismantled one after another.
In the public opinion arena, Tutu is even more dominant, and Shen Shen can only make a few sarcastic remarks in secret.
Due to the success of Musk’s starship, the aerospace field is one of the few fields that the gods can think of with their heads held 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 battle of public opinion.
At 12 noon, Hua Guoyang’s 30-minute news program gave the gods a painful blow.
“According to official news from Huaguo Aerospace Science and Industry, the Shenzhou-Guangjia electric rocket jointly built by Huaguo Aerospace Group and Guangjia Aerospace Group was successfully launched today. A pure electric rocket based on electromagnetic launch superconducting technology and plasma engine technology will be used to launch small satellites in the future
According to reports, the success of this test marks the application of normal temperature superconducting technology in rocket launches. A major breakthrough has been made in the field. According to official news from China Aerospace and Guangjia Aerospace, a composite power recyclable rocket based on the same technical framework will be launched by the end of this year at the latest. After the successful launch, it is expected to achieve a significant reduction in rocket launch costs. ”
After the host’s introduction, there was a simple interview. The interviewee was the person in charge of Huaguo Aerospace of the entire project.
After the program was broadcast, various official blogs simultaneously posted on Weibo.
Everyone can only vaguely see from the video that the huge launch tower is different from the red and yellow light when other rockets are launched. There is no light during the entire rocket launch. It is directly electromagnetic driven and the rocket disappears into the sky with a swish.
"Shenzhou-Guangjia rocket successfully launched" quickly topped the Weibo hot search list.
Weibo, Zhihu, Douyin and other platforms are all discussing this matter.
“I can only say that I have only heard of co-branded milk tea and coffee blind boxes in the past. This is the first time I know that there is a co-branded rocket launch.
I would like to ask Huaguo Aerospace or Guangguo Optoelectronics "Aerospace, can you bring our company to the next collaboration? We can negotiate any amount of sponsorship," a senior executive from a major mobile phone manufacturer said on Weibo.
After Lei Jun saw it, he took it seriously. He felt that based on his personal relationship with Chen Yuanguang, it was not impossible to build a light-armor-Xiaomi account. Xiaomi would be responsible for air-conditioning the space station, right?
“Thank you, room-temperature superconductivity is indeed the Holy Grail of physics. In the past, there have been voices saying that room-temperature superconductivity is not that powerful and has not changed our lives.
This kind of statement is most common among some people. In short, it doesn’t matter as long as the technology that China has broken through is not important. The technology that China has not mastered is the crown jewel of human science and technology. The only regret is that the crown jewel seems to be Not much anymore.
Speaking of room temperature superconductivity, the quantum computer built by Malaysian Alpha Technology using room temperature superconducting technology at the beginning of this year taught the world a lesson
If you say that. Attributing that to quantum computers, why can’t the United States build a quantum computer of this level? Isn’t it because the basic materials are stuck?
Of course you can say it’s not because of room temperature superconductivity, but this time it’s always because of room temperature superconductivity, right?
The rocket launch broadcast in the official video this time is different from all the rocket launch scenes I have seen before. There is no fuel burning. I remember clearly that the host introduced two rockets in the 30-minute news , one pure electric and one hybrid powered. This time it is a small rocket that is purely electric.
As we all know, rockets use speed to escape the gravitational constraints of the earth. All previous rockets that left the earth used fossil fuels, which used the high-temperature and high-speed jets generated by fuel combustion to generate powerful reaction forces, continuously accelerating and lifting them until they flew out of the atmosphere.
So we will see a lot of light produced by combustion during rocket launch.
However, existing rockets basically take off directly from the ground launcher. In order to accelerate away from the troposphere where the air is dense and has high resistance, a large amount of fuel is consumed.
In the past, in order to reduce losses, there were various solutions, including air launch of aircraft-mounted rockets, balloon lift rockets to high altitude launches, centrifuge-thrown rocket launches, etc.
Like Americen’s Pegasus air-launched rocket in 1990, it was suspended under the belly of a passenger aircraft before launch. When the aircraft climbed to an altitude of about 13,000 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 when using aircraft as a launch platform. Its operation and maintenance costs are high, and its transportation capacity is limited. Generally, it can only launch small rockets, and its transportation capacity into orbit is insufficient.
That is to say, the cost is high. 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 that it uses normal temperature superconducting Materials and overall energy requirements will also be much lower.
After reading it, I only had one feeling, that is, I will not be able to sleep. Will the compression of overall costs, coupled with the normal temperature superconducting electromagnetic launch pad, make China's supersonic missiles faster, more difficult to intercept, and cheaper to launch? I can think of it, but the United States can't think of it?
Supersonic missiles are inherently difficult to intercept, now they must be even more difficult to intercept?
As well as possible electromagnetic guns in the future, room temperature superconducting technology is enough to make the United States on pins and needles.
As for the composite power rocket mentioned in the news, the achievable cost in the publicity has dropped significantly, I can only say to wait for the news, wait for the official news.
Let’s see whether the cost of China’s solution is lower, or whether the cost of the starship solution proposed by Musk is lower.
Looking at it now, room-temperature superconducting technology is the Holy Grail. To use the same saying, people are glad that technology is in the hands of civilization. If Americen achieves a technological breakthrough, I simply can’t imagine the consequences. The United States should just keep mastering civilized technologies like GPT. "
"Thank you for the invitation. As an industry insider, this project is very confidential. I had never heard of it before it was successful.
I have inquired with many colleagues, and no one has heard of it. It is like it came out of nowhere.
Having said that, it is perfectly normal for China’s aerospace industry to engage in superconducting electromagnetic launches.
Long before the birth of room-temperature superconductivity, whether it is official information or the information I know, China Aerospace has been doing research on superconducting electromagnetic launch systems.
It's just that it was like studying to see the effect first, and raising this team. If superconducting technology achieves a breakthrough, it can quickly enter the formal research and development state.
Even before room temperature superconductivity existed, the Third Academy of Aerospace Science and Industry also conducted an electromagnetic launch high-temperature superconducting electric levitation navigation test, achieving a test speed of 234 kilometers per hour on a 380-meter line.
After the birth of room temperature superconductivity, even one-dimensional room temperature superconductors can be directly used in this electromagnetic emission system.
From the video, you can see that China Aerospace and Guangjia Aerospace are building a maglev 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 avoiding friction between the rocket and the track to cause resistance. The acceleration coil provides the rocket with strong take-off thrust, helping it rush out of the dense air as quickly as possible. height near the ground.
When the rocket is fully accelerated by the launcher and breaks out of the troposphere, the first-stage engine is ignited, continues to accelerate and climb, and finally enters orbit.
Because room-temperature superconducting materials do not need to be equipped with a cooling system, the entire launch device can be made large in scale and can be used repeatedly.
In addition, the Shenzhou-Guangjia is a purely electric rocket with no fossil fuels. Its structure can be made very simple and very light.
I can only say that it is awesome, and I can roughly guess the technical details inside.
Compared with this public rocket, I am more curious about how the composite power rocket is designed.
I don’t know whether the entire project is led by Guangshen or China Aerospace. I only hope that there will be more revelations after its success.
But no matter what, I feel 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: oxidizer-fuel-engine system. The oxidizer and fuel are gone, and there are only engines and electric energy to drive. This is a huge breakthrough in the field of aerospace. I have a hunch that I will really see the arrival of the commercial aerospace era in my lifetime.
The long-term future that I am more looking forward to is that it will be a pure electric rocket without electromagnetic drive. It depends on when the energy density can break through. ”
China’s technological breakthroughs in the aerospace field have caused a sensation not only in China, but also around the world.
For foreigners, due to the large-scale deployment of China's new energy vehicles overseas, 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 now Relatively positive.
At least outside the traditional American forces, public opinion is becoming more and more friendly to China.
A certain YouTube video quickly exceeded 1 million views. Most of the comments below were congratulatory, and a few were angry.
“Congratulations to China for achieving a breakthrough in aerospace technology.”
“I increasingly believe 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 accelerate"
"When China says yes, then we will do it ourselves and do it better. , American had just finished saying: Wait, that’s not the goal, and China used it too late to fight back.”
“I have always seen Westerners saying on YouTube that China does not have it. Developing their own technology, they stole it from us, and they tried to take credit for China's technological progress. What's even more interesting is that I'm curious if anyone will say that China stole this electric rocket. Are you here? I mean, how can China steal something that you don’t have?”
“Wright is the best scientist in the 21st century. He has single-handedly led China’s scientific and technological progress, and I have to say India. The biggest dilemma at present is the lack of India’s Leite.”
