Chapter 104 Impact
“That’s the rocket engine. Why Falcon 9’s low-Earth orbit carrying capacity is as high as 22.8 tons, because they have the largest thrust engine among the rockets in service today.
Falcon 9 uses 27 Merlin 1D engines, providing a total of 2,280 tons of thrust. This will be the biggest obstacle for Light Armor Aerospace to catch up with Falcon 9. At present, domestic engines that benchmark Falcon 9 are still in the demonstration stage. The carrying capacity of the Long March 5 is about half that of the Falcon 9, and it is still in the experimental stage.
I think Guangshen can consider cooperating with Tianbing Technology. They are developing the Tianlong 3. Their engine thrust is . 770 tons, if this thrust can be bundled with multiple engines like the Falcon 9, it is possible to catch up.
It would be a waste of time and resources to start a large-scale rocket launch all over again. A kind of waste.”
"Thank you for the invitation. This is definitely a launch worth remembering. It represents that China's commercial aviation has entered a new stage. Although there is a gap between the launch yield and carrying capacity of Pioneer 1 and Falcon 9, according to my Guangshen calculated the information disclosed in Tim’s interview and found that its launch cost is not much higher than that of Falcon 9.”
It is rare to see a group of science and engineering bloggers on Zhihu answering questions so actively .
Chen Yuanguang was in Jiuquan to watch the launch of Pioneer 1 live, while Lin Jia was far away in Shenhai watching the live broadcast.
Because she has a lot of work on her hands and a lot of business negotiations, she has no time to go to Jiuquan.
After seeing the rocket successfully enter orbit, she felt relieved, which meant it was easier to negotiate the price.
"Mr. Lin, congratulations to Guangjia Aerospace for its new glory. This morning I was watching the live broadcast on my laptop in the hotel. After your staff announced that the launch was a complete success, I was also happy for you." Zhang Yi said.
Lin Jia knows that Jiangcheng University’s alumni work has been very successful and it has firmly occupied the top ten positions in the alumni donation rankings over the years. This is a very difficult thing.
Being in the top ten all year round means that you have the strength of the top five, which places very high requirements on alumni management.
You can only do this if you can build a sufficient resource exchange platform.
Therefore, with Lei Jun's help, Jiangsu University hopes to contact Chen Yuanguang for further communication. Lin Jia, as Chen Yuanguang's representative, will carry out specific communication.
Most powerful universities in China basically have alumni management departments. This department at Jiangsu University is called the Alumni Affairs and Development Liaison Office. Zhang Yi is the director of the Resource Development Office under the office.
In other words, he is specifically responsible for liaison with Jiang University alumni. Of course, there are not many occasions where he appears in person, and he generally does not need to be present for such early contacts.
This time it is because Chen Yuanguang is of great significance to Jiangcheng University. If people like Lei Jun and Chen Dongsheng are the present, then Chen Yuanguang is the future, which is enough to support the resource exchange of Jiangcheng University Alumni Association for decades to come. The future of changing platforms.
After hearing this, Lin Jia smiled and said: "Director Zhang, Yuan Guang almost works besides sleeping and eating. We can produce such results in just one year. Yuan Guang's dedication is the decisive factor.< br>
And we have not only made progress in recyclable rockets, but also in the fields of new materials and biomedicine. It is indeed not easy to achieve these results. ”
Although it is possible to go to the future to obtain technical data, it is not a simple matter to just transport the technical data from the future to the present and then reproduce it in the technical system of modern time and space.
This is like going back to ancient times with a search engine and trying to develop a truly usable steam engine. There are many difficulties to overcome.
After listening, Zhang Yi nodded repeatedly: "I can understand it completely.
Before coming, I also specifically talked to you and Dr. Chen's teachers in college about their evaluation of you. Very high, especially Dr. Chen, who was a very popular figure when he was in school.
I have always done administrative work at Jiangsu University and have never taught a class. I have been there since I was hired as the director of the Resource Development Office in 2017. I have never come into contact with front-line students. I heard Dr. Chen’s name during his senior year.
Colleagues in our office are discussing that he has published several Nature articles and went to MIT for exchange. They all feel that Dr. Chen will return to Jiangnan University to teach after graduating from MIT, and we can introduce top talents again.
It’s just that Dr. Chen’s development path and speed far exceed our imagination. ”
Previously, Jiang University had been the dean of the School of Biology and the Dean of the School of Chemistry, who personally kept in touch with Chen Yuanguang.
But when Chen Yuanguang embarked on the road of entrepreneurship and developed rapidly, he poached him. The path of returning to Jiangnan University to teach was cut off.
It was also impossible for the two deans to mobilize Chen Yuanguang to participate in Jiangnan University’s alumni activities.
Therefore, Jiangsu University wanted to re-establish communication channels. Unfortunately, there was no suitable opportunity. This time the opportunity came.
When the opportunity came, Jiang Da quickly contacted Lei Jun, hoping that Lei Jun could help with it and help connect people.
When Lin Jia heard about his time in college, good memories came to his mind. Compared with the high-intensity work now, his time in college was simply wonderful.
Including that time, Chen Yuanguang had a lot of time to accompany her to the library, climb Luojia Mountain, go for a walk at the Olympic Games, and go to the Plum Garden to watch movies.
Now I want to watch a movie together. Either Chen Yuanguang doesn't have time or she doesn't have time. The work intensity is even more exaggerated than that of 996.
"Director Zhang, thank you for the compliment. Yuanguang University worked really hard and made many outstanding scientific research results. I was as surprised as you at that time.
Before he published Nature, I always thought that he was not interested in scientific research. Interested." Lin Jia said.
Zhang Yi went on to make amends: "It goes without saying that Dr. Chen's achievements are well understood by everyone. Compared with him, you are also very good and can rank in the top ten percent of the School of Economics and Management. This is also not true. What an easy thing.”
At that time, the School of Economics and Management had the highest admission scores in Jiangsu University, especially the mathematical finance experimental class. and a double major in finance.
So the School of Economics and Management is very busy.
Lin Jia said embarrassedly: "I still rely on Yuan Guang to give me extra lessons in mathematics. My own efforts are only part of the reason.
Director Zhang, as we chatted, I started to miss my college days at Jiangda. "
Zhang Yi quickly borrowed the donkey from Poxia: "Jiang University welcomes you back to visit your alma mater at any time. We can make a reservation when the cherry blossoms bloom in March. If Dr. Chen is willing, it is best to trouble him to come there. The new gymnasium will give everyone a Luojia lecture.
Many high school students who have applied to Jiangnan University in the past two years have gone there for Dr. Chen, especially the School of Chemistry and Biology. ”
Lin Jia. Nodding, she thought it was best not to jump into sinkholes like biochemical environmental materials. She then thought about it, in today's environment, anything could become a sinkhole.
Seeing that Lin Jia didn't answer, Zhang Yi continued: "We came here this time to reach cooperation with Guangjia Aerospace.
We launched the Luojia-1 remote sensing satellite in 2018. At that time, Luojia Satellite No. 1 is relatively small, and is mainly used for night light remote sensing. Its range of uses is relatively narrow.
We have recently been developing Luojia 2, which is expected to be completed next year. Enrich their detection methods and detection capabilities at the Remote Sensing Institute.
Compared with Luojia-1, the functionality will be qualitatively improved.
We hope to package the launch of Luojia-2. Light Armor Aerospace is here to help us launch.
Our needs are relatively simple, and it only needs to be put into orbit in one go. "If there is no Guangjia Aerospace, Luojia 2 will be launched with one stone and three satellites. That is to say, one rocket will launch three satellites, and the three satellites will successively detach from the rocket and enter orbit. This kind of launch cost is relatively low. < br>
Lin Jia said: “No problem, Guangjia Aerospace has this qualification.
It’s just that we have not carried out similar business before, so we still need to discuss the specific quotation internally.
You need to give more detailed requirements, like the weight of the satellite and what orbit it is expected to enter.
In my impression, Luojia-1 is a remote sensing satellite, and Luojia-2 should also be a remote sensing satellite, right? Lin Jia asked.
Zhang Yi said: "Yes, it is also a remote sensing satellite." "
Lin Jia said: "It depends on whether Jiangda wants to launch to polar orbit, non-polar low earth orbit or geostationary orbit.
According to your different needs, the quotation will naturally be different. ”
Zhang Yi was shocked. According to his information, Lin Jia graduated from the School of Economics and Management and studied liberal arts in high school. How could he know so much about aerospace?
As a science and engineering graduate, he couldn't even understand the difference between these tracks.
Lin Jia is good at observing people's emotions, and she has developed a sharp eye after the experience of starting a business. She felt a little proud after seeing Zhang Yi's shock. Going to Jiaotong University to attend the professional courses of the Aerospace College was not in vain. .
Lin Jia must wear a mask every time he goes to Jiangda to avoid being recognized.
Because with the launch of Guangjia Technology, she was discussed a lot by various media, including her own interview on Station B, which led to her high face recognition.
Lin Jia didn’t want to cause an accident.
Zhang Yi suppressed the shock in his heart and said, "When I go back later, I will ask our Luojia 2 project team to sort out a detailed requirement for you. I will ask Guangjia Aerospace to give you an evaluation price at that time."
Lin Jia said: "No problem."
Zhang Yi came with the mentality of having sex for nothing. He originally thought that Guangjia Aerospace would help them launch Luojia 2 for free, but in the end he still had to pay.
But he didn't care. The school's money was not his money anyway, and the school leader didn't mean to send him here for free. It was just his own guess.
After the successful launch of Guangjia Space, Jiang Da hopes to let Guangjia Space launch satellites for them. Tim also has similar thoughts.
At the simple celebration banquet held at noon that day, Tim and the others also joined in the fun.
Chen Yuanguang went from table to table to toast with everyone with water instead of wine. He walked to Tim's table and said, "Thank you all for coming. Please remember to make me look more handsome in the video later."
Arousing laughter on the table, the aura of the God of Light disappeared instantly, making Chen Yuanguang look much more real.
Tim approached Chen Yuanguang: "Guangshen, I have an idea. We also want to launch a satellite. Does Guangjia Aerospace provide such services?"
Chen Yuanguang asked doubtfully: "Ah? Aren't you guys making videos?
There is no problem with launching, but you have to think clearly about the purpose of your launch. If it is just to shoot a video with a theme, then the cost is a bit high.
Not to mention that Guangjia Aerospace can give you discounts, the price of just buying satellites is not much cheaper. "
Tim murmured: "God of Light, I just saw the beauty of the Pioneer 1 launch in the sky today, and I have the urge to launch a satellite belonging to our channel.
As for what role this satellite will play, we still have to go back and think about it. I just make sure that Guangjia Aerospace can do this. I will communicate with Mr. Li and others in detail later. ”
Mr. Li pointed out that Li Haide is responsible for all matters related to external communication.
Chen Yuanguang understands that this kind of space romance is a temptation that men cannot resist, "No problem, just ask if you need it."
The successful launch of Pioneer 1 has brought a lot of potential business to Guangjia Aerospace, but this It's not all good news and no bad news.
The breakthrough in perovskite technology of Light Armor Aerospace and the successful launch of satellites, these two things together, successfully stimulated the White House.
Before the Chinese Lunar New Year, the Department of Commerce of America published the latest administrative measures in the Federal Register, adding 13 companies to the entity list, including 2 Chinese companies, one of which It’s Light Armor Aerospace.
In addition to not being able to purchase Amerikan technology, Guangjia Aerospace is also included in the import list. Technologies and products are not allowed to be sold to Amerikan.
"Light Armor Aerospace will threaten Amerikan's energy security and aerospace security, and it is very important to Made in China 2025."
The fear of Light Armor Aerospace is undisguised.
Affected by this, the launch contract signed by Guangjia Aerospace and SpaceX can only be terminated early. You must know that there are still two launch opportunities that are useless.
Originally, Americen's photovoltaic companies were waiting to introduce the new generation solar technology of Guangjia Aerospace to achieve substantial profits.
Media they fund questioned American’s decision at a press conference:
"Mr. Miller, it is known that Guangya Aerospace has achieved a breakthrough in the new generation of solar cells. Will the inclusion of Guangma Aerospace on the list have an important impact on the development of the federal photovoltaic industry?
Our own Without federal subsidies, it will be difficult for photovoltaic companies to compete with Chinese companies. Will adding Guangjia Aerospace to the list exacerbate the bad situation our photovoltaic companies face in the global market? ”
< br>Matthew Miller replied: "This is out of consideration for Amerikan's safety.
In terms of business competition, we will increase our support for the photovoltaic industry and urge our allies to Launch an antitrust investigation into Guangjia Aerospace’s new generation solar cell technology.”
Huaguo reporter asked: “Mr. Miller, in response to your answer just now, can I think that Guangjia Aerospace is willing to transfer the new generation of solar energy. Technology, Amerikan is willing to make concessions on zhicai?”
Matthew Miller said unabashedly: "Yes, if Guangjia Aerospace is willing to transfer technology, we will kick it off the import list."
In other words, the technology can be sold to Amerikan enterprise.
No Western reporters present felt wrong with this straightforward attitude. European reporters were thinking that European photovoltaic companies must rush to reach a technology transfer agreement with Guangjia Aerospace to win a time window.
