Chapter 93 Recyclable Rockets
The money in aerospace is just a foundation.
In many cases, money is not enough. You also need resources, talents, sustained investment, and long-term planning.
In the international space race and commercial aerospace, countries with a certain voice in the aerospace field, such as France, Germany, Neon, and China, are still investing money and still have expectations, hoping not to fall behind in the aerospace field.
Asan and Gao Li have also been investing, and Asan even believes that he can compete with China in the aerospace field.
In fact, none of them have comprehensive competitive strength. They are competitive in a certain field at most. This kind of competitiveness cannot be used to form a breakthrough.
In the aerospace field, there are only two players, China and American. American’s advantages are talents, investment and technology.
Huaguo’s advantage is its mechanism of long-term planning, continuous investment, and concentrated efforts to accomplish major things.
For small countries, if they develop the gamma ray detector mentioned above, they have to obediently pay tribute to Amerikan's aerospace industry.
It is impossible to leave you as the moat of the aviation industry.
"If there is still no improvement after pouring in 2 billion US dollars, I can still mortgage my shares of Guangjia Technology and borrow money from the bank to invest in this project.
Guangjia Technology is now "Aerospace is the future, it can give hope to the world," Chen Yuanguang said.
In the beginning, Chen Yuanguang started aerospace just to protect himself. He needed a long-term systematic project, and he was indispensable for this systematic project.
Guarantee your position through such systematic projects.
So he proposed the asteroid mining plan. Once this plan is put into operation, the resources it can mobilize will not be lower than any scientific research project.
With the advancement of the project and the listing of Guangjia Technology, Chen Yuanguang has seen a lot during this period. The problems that exist around the world mainly include two aspects. On the one hand, there is wealth distribution. The top level has accumulated too much wealth and is unwilling to give benefits to the middle and lower levels.
This is true at home, and it is also true abroad.
The rich would rather donate hundreds of millions of dollars to charity funds than raise the wages of their employees. They will lay off employees if they should.
On the other hand, it is because science and technology has not made breakthrough progress for too long, productivity growth is also weak, and social wealth lacks an increase.
The consequence of the lack of breakthroughs in science and technology is that humans lack confidence in the future. The consequence of weak productivity growth is that it is becoming more and more difficult to find employment and wages are getting smaller and smaller.
Combining future history, Chen Yuanguang realized that starting the space age was the solution to the current situation, and if the age of space navigation could be started fifty years in advance, the outbreak of World War III would also be postponed.
He can change the future to a certain extent, a more peaceful future. As for what this future will be like, he doesn't know, because it is not the same time and space.
As for the AI breakthrough that Amerikan will be hyping up in the near future, there are technological breakthroughs, but it will take time for these technological breakthroughs to be transformed into breakthroughs in productivity and scientific research methods. At least in ten years, it is impossible to transform it into a tool to leverage productivity so quickly.
As for the uproar in global public opinion, it is entirely to cooperate with the creation of gods and increase the market value of the core of the US stock market, the technology giants.
The soaring market values of these technology giants, such as Nvidia, Microsoft, and Google, have further exaggerated the atmosphere on the eve of the technology explosion. The two are mutually exclusive, creating the impression that America is still a country on the top of a mountain. hallucination.
Whether GPT or SORA, they have achieved technological breakthroughs, but it is far from being able to truly say that AI artificial intelligence has brought productivity subversion and production relations transformation.
American needs such a reported victory to cover up the stalemate on the front.
Using exaggerated battle reports to prevent the U.S. stock market from collapsing, and observing the reality through the appearance, you will find that the major technology giants account for about 30% of the total market value of the S&P 500, and they contribute nearly half of the S&P 500 return.
American must do its best to prevent these technology giants from collapsing. In fact, the market value of these companies is seriously overvalued compared to two years ago.
Intel's dynamic price-to-earnings ratio has soared to more than 100. When I saw it, I thought it was Myanmar A.
When Chen Yuanguang studied the future development of commercial aerospace, he knew very well that this period of time is just the eve of the outbreak of AI, and the eve is very long.
Only until the day when humans lose confidence in AI and doubt whether AI can really replace humans will breakthroughs in basic materials, chip technology, and communication networks be achieved, will AI truly bring about complete changes to humans. .
Before that, commercial spaceflight was much more reliable.
Lin Jia put his hand on the dining table and motioned to Chen Yuanguang to pass it over: "Relax, I believe you."
Chen Yuanguang held her hand and felt a chill coming from him: "I'm not nervous.
Failure is not terrible. Asteroid mining is a long-term project, and there will be many failures in the process.
I have long been prepared to experience a hundred failures. "
Lin Jia said: "One hundred times is too many, ten times is about the same. ”
After the success of Guangjia Technology, Lin Jia had unconditional trust in Chen Yuanguang. Even if Chen Yuanguang told her that he was an alien, Lin Jia would believe it, and she would even feel relieved in her heart.
After Guangjia Technology went public that day, Lin Jia first sent Chen Yuanguang’s parents back to the hotel, and then went to her parents’ home in Shenhai to stay for a while
"The leaders I met today are much bigger than those I saw in Hangzhou. It seems that the national level is very optimistic about Chen Yuanguang!" Lin Qinghua said with emotion. It is not that he has never been listed. The position researcher came to support him.
As for Chen Yuanguang this time, Shen Hai, the China Securities Regulatory Commission, and the Ministry of Health all gave him enough face, and a lot of big guys came.
It was an eye-opener for Lin Qinghua.
Lin Jia replied: "Of course, human hibernation is a monopoly technology, and it is a high-tech monopoly technology, not a microbial monopoly."
Lin Qinghua didn't react at first, his brain turned. It took me a moment to realize that Lin Jia was talking about Jiangxiang Technology, "Don't say this kind of thing outside.
Your identity is different now. If you say this and the media finds out, it will be a big hype. "
Mother Lin clapped his hand hard: "My daughter is already old, and she still doesn't know what she can and cannot say? Want you to teach?
Finally, we, a family of three, get together here. Don’t act like dads all the time and pretend to be educating people here.
Nanny, I've been shopping with Chen Yuanguang's mother in Shenhai these days. I've had a sneak peek and found out that your mother is very satisfied with you. When we talked about getting married, her mother also thought that we should get married as soon as possible. .
Qinghua, how was your conversation with his dad? "Mother Lin turned her head and stared at Lin Qinghua.
Lin Qinghua thought to himself, how do I know? I have been asking Lao Chen how to fish and how to adjust erbium these past few days. How can I still remember this?
"We had a good chat. He is also very satisfied with Lin Jia. How could anyone be dissatisfied with my daughter." Such words naturally come out of his mouth.
Lin Qinghua thought for a while, fishing friend Lao Chen and I also agreed to go to Yangcheng and he would take me fishing. He should not refute me.
Mother Lin applauded: "That's good, Nannan, what do you think? If you and Yuan Guang have no objections, we can handle this matter as soon as possible.
As for In terms of property, you can have your property notarized before your marriage to avoid giving Yuan Guang the illusion that you are anxious to get married just after his company went public
Our family definitely doesn’t want anything material from him, we just think it’s not easy for the two of you to succeed together from college to going abroad and now starting a business together. This rare fate should be cultivated into a positive result.
His mother and I both mean the same thing. "
Mother Lin has a tough attitude. She is also worried that things will take too long to change, and she wants to settle it as soon as possible. Lin Qinghua will naturally not refute, and he is happy to do so.
Lin Jiafuer, she doesn’t want to get married, even now, she still doesn’t want to, she thinks it’s good to maintain the status quo, why should she get married?
Marriage is a shackles for yourself.
The problem is that if you say something like this, you will be chanted to death.
"Okay, parents, just leave me alone. I know my own rhythm." Lin Jia dealt with it casually.
Mother Lin obviously didn't want her to deal with it like this: "Then you can discuss it with Yuan Guang when you go back today. It's best if both parents are in Shenhai this time. Ceremonies like engagement can be done directly. We It's very convenient for relatives from over there to come to Shenhai, and it's also very convenient for relatives from over there to charter a plane." Mother Lin was very persistent.
Lin Jia resorted to procrastination: "I've been too busy recently. Let's wait for a while. The company just went public recently. Guangjia Aerospace launches rockets worth 20 million dollars a time. I really don't have the energy to care about this.
After a while. "
"Boss, the data from SpaceX has been returned, and the detector has now entered the predetermined orbit.
The data monitored during the SpaceX launch process has also been sent back simultaneously.
We are going to start analysis later. "Lin Tianmin, a scientific researcher at Guangjia Aerospace, is currently the temporary head of the recyclable rocket team. He just graduated with a doctorate and left his job before the probation period of the aerospace institute ended and came to Guangjia Aerospace.
Currently, there is not a single expert in the entire Guangjia Aerospace industry. They are all freshly graduated masters and Ph.D.s
It’s not that they haven’t found people, Guangjia Aerospace’s treatment and vision can still recruit some people, but it’s because those people are still in the desensitization stage.
They hired the core R&D personnel of the Long March 9 from the Aerospace Institute. The photodesensitization period started for one year, and the desensitization is not over yet.
Everyone else is pretty much the same, because Light Armor Aerospace only wants elites, so the people they poached are either desensitized or still struggling with the original unit.
What the original unit means is that the core projects can’t be done without you. As for why I’m only getting a salary of 200,000 yuan without you, I don’t know.
“Okay, our first phase of recyclable rockets will definitely adopt the mainstream solution, using liquid oxygen/methane engines.
In the long term, my idea is to use solid-state batteries, where we use electricity as thrust.
In this case, our recycling ratio can be further reduced and the cost can be greatly reduced. ”
Using fossil fuels is one-time use, and it’s done after use, but using solid-state batteries, solid-state batteries can also be recycled. After recycling, they can be recharged and used again.
Rocket first stage, The return cover can be recycled, the recycling rate can be increased to 90%, and the cost is estimated to be reduced to less than 2 million, the unit is RMB.
After hearing this, Lin Tianmin said doubtfully: "Boss, the electric thrust is backward. It has been said that some satellites are also using Hall electric propulsion to control direction.
But solid-state batteries are a bit far away. "
Chen Yuanguang shook his head: "No, solid-state batteries are about to be mass-produced, what are you thinking about?
Wanwan Huineng, their solid-state battery production line is already being set up, and it is estimated that it will be in full production next year.
We need to increase the energy density and thrust-to-weight ratio to achieve electric propulsion. ”
The person at the helm of systematic engineering needs more literacy. He needs to know enough things to be able to find the direction immediately.
"Of course, the current focus is definitely on fossil fuels. It will take about three years. In three years, we will start exploring electric thrust rockets." Chen Yuanguang said.
Lin Tianmin nodded: "Okay."
Chen Yuanguang continued: "I saw the recyclable rocket you designed. It generally adopts a bare rod and no pusher design.
< br>Then a grid rudder is used on the first stage for post-launch recovery.
The engine is the same as the Falcon 9, using a parallel strategy of multiple liquid oxygen/methane engines, including the second stage. Two engines are connected in parallel.
In fact, I think this design is open to discussion.
There is no need to imitate the design of the starship for the time being.
How should I put it? Your overall design idea is very strange. It draws on the design ideas of the Long March series of rockets, as well as the design ideas of the Falcon and Starships.
We have not launched once yet. If you add two more engines to the second stage, it will easily cause problems during vertical soft landing.
Look”
Chen Yuanguang said the following and began to calculate directly on the whiteboard in front of his desk: "The final result is that the probability of something happening during a soft landing is more than half.
This plan is definitely not feasible."
Lin Tianmin said nothing, lost in thought, and at the same time a little shocked inside.
As they worked together during this period, or to be precise from the day of the interview, he knew that Chen Yuanguang really understood it, and he knew it better than they, PhDs in the aerospace field.
But he did not expect to understand it to this extent.
Just by looking at the design drawings, you can directly tell what is wrong with your design, and theoretical calculations can prove that there is indeed something wrong with your idea.
This is more than one rank higher than them.
You are also in your twenties and you are so good at chemistry, which makes Lin Tianmin very frustrated.
"Boss, I understand. I'll go back and think about it." Lin Tianmin couldn't help but feel a little disappointed in his tone.
Chen Yuanguang waved his hand: "Go ahead, this plan will definitely not work.
But it’s already good to have such a plan in the first version.
We can learn from the ideas of Long March 9 and Starship, but at most we can only learn from it. We have to go our own way. ”
Chen Yuanguang knows that no matter what plan they come up with, there is a 99% probability that it will not be used.
In the end, they will definitely have to find a mature series of plans from the future time and space. Come and use it.
But you still have to cultivate talents. The hundreds of PhDs you have recruited have to carry the weight of the project. No matter how good he is, he cannot transfer all the technologies by himself.
This is just like after you are reborn, it is impossible to write out the Battle of the Sky by memorizing it. The best way is to memorize the storyline and then find a writer to complete and polish it.
Slowly return to form over the weekend!
Weekends are definitely better
