Chapter 93 Reusable Rockets

When it comes to space travel, money is just a foundation.

Many times, money is not enough; you also need resources, talent, sustained investment, and long-term planning.

In the international space race and commercial space, countries with a certain voice in the space field, such as France, Germany, Japan and Russia, are still investing money and have expectations, hoping not to fall behind in the space field.

Asan and Gaoli have also been investing continuously, and Asan even believes that he can compete with China in the field of aerospace.

In fact, they do not have comprehensive competitive strength. At most, they are competitive in a certain field. This competitiveness cannot lead to a breakthrough.

In the aerospace field, there are only two players, China and America. America's advantages are talent, investment and technology.

China's advantages lie in its long-term planning, sustained investment and mechanism of concentrating resources to accomplish major tasks.

For small countries, if they develop a gamma-ray detector like the one mentioned above, they have to pay tribute to America's aerospace industry.

It is impossible to leave it to you as a moat for the aviation industry.

“If there is still no improvement after investing $20 billion, I can still use my shares in Light Armor Technology as collateral and borrow money from the bank to invest in this project.

Light armor technology is the present, and aerospace is the future, it can give the world hope." Chen Yuanguang said.

At the beginning, Chen Yuanguang was involved in aerospace just to protect himself. He needed a long-term systematic project, and this systematic project could not be done without him.

Ensure your position through such systematic projects.

Therefore, he proposed a plan for asteroid mining. Once this plan is implemented, the resources that can be mobilized will be no less than any scientific research project.

With the advancement of the project and the listing of Guangjia Technology, Chen Yuanguang has seen a lot of problems in the world during this period. There are mainly two aspects. On the one hand, there is wealth distribution. The top level has accumulated too much wealth and is unwilling to give concessions to the middle and lower levels.

This is the case both at home and abroad.

The wealthy would rather donate hundreds of millions of dollars to charity funds than increase their employees' salaries and will still lay off employees when necessary.

On the other hand, it is because there has been no breakthrough in science and technology for a long time, productivity has also been growing sluggishly, and there is a lack of increase in social wealth.

The consequence of the lack of breakthrough progress in science and technology is that mankind lacks confidence in the future, and the consequence of the sluggish growth in productivity is that it is becoming increasingly difficult to find a job and wages are getting lower and lower.

Combining future history with his own, Chen Yuanguang realized that ushering in the Space Age was the only way to solve the current situation. Moreover, if the Space Age of Navigation could be started fifty years in advance, the outbreak of World War III would also be delayed.

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 in the same time and space.

As for the AI ​​breakthroughs that America will be hyping in the near future, there have been technological breakthroughs, but it will take time for these technological breakthroughs to be transformed into breakthroughs in productivity and breakthroughs in scientific research methods, at least ten years. It is impossible for them to be transformed into tools to leverage productivity so quickly.

As for the uproar in global public opinion, it is entirely to cooperate with the deification and drive up the market value of the core of the core of the US stock market, the technology giants.

The soaring market value of these technology giants, such as Nvidia, Microsoft, and Google, further exaggerates the atmosphere on the eve of a technological explosion. The two complement each other, creating the illusion that America is still the country on the top of the mountain.

Whether it is GPT or SORA, they have achieved technological breakthroughs, but it is still far from being able to truly say that AI has brought about a disruption in productivity and a transformation of production relations.

America needed such a victory in battle reports to cover up the stalemate on the front line.

Exaggerated battle reports are used to prevent the U.S. stock market from collapsing. If we look beyond the surface and observe the essence, we will find that several major technology giants account for about 500% of the total market value of the S&P 30, and they contribute nearly half of the returns of the S&P 500.

America 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 studying the future development of commercial aerospace, Chen Yuanguang was very clear that this period of time was just the eve of the AI ​​explosion, and the eve would be very long.

Until the day comes when humans lose confidence in AI and doubt whether it can really replace humans, and breakthroughs are made in basic materials, chip technology, and communication networks, AI will truly bring about a radical change to mankind.

Until then, commercial spaceflight is much more reliable.

Lin Jia stretched out his hand and placed it on the dining table, motioning Chen Yuanguang to hand it over: "Relax, I believe you."

Chen Yuanguang held her hand and felt a chill coming: "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 was prepared to fail a hundred times."

Lin Jia said: "One hundred times is too much, ten times is about right."

After the success of Light Armor 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 even feel relieved that this was the case.

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 and stayed for a while.

"The leaders I met today are much more important than the ones I met in Hangzhou. It seems that the national level is very optimistic about Chen Yuanguang!" Lin Qinghua was very emotional. It's not that he has never gone public before. When he went public, at most the China Securities Regulatory Commission sent a researcher with a rank but no position to support him.

This time, Chen Yuanguang was given enough face by Shenhai, the China Securities Regulatory Commission and the Ministry of Health, and a bunch of bigwigs came.

It opened Lin Qinghua's eyes.

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, but it took him a while to realize that Lin Jia was talking about Jiangxiang Technology, “Don’t say this kind of thing outside.

Your identity is different now. If the media knew what you said, it would just be a hype."

Mother Lin clapped his hands vigorously and said, "My daughter is already grown up, and she doesn't know what she can and can't say? Do you need to teach her?
It's not easy for our family of three to get together here. Don't always act like a father and act like you're educating us.

Nannan, I have been spending the past few days in Shenhai with Chen Yuanguang's mother. I did find out what she said and she said that his mother is very satisfied with you. We talked about marriage and his mother also thinks that you should get married earlier.

Qinghua, how was your conversation with his father?" Mother Lin turned her head and stared at Lin Qinghua.

Lin Qinghua thought, how would I know? I have been asking Lao Chen how to fish and how to adjust the bait these days, how could he still remember this?

"We had a good chat, and he was very satisfied with Lin Jia. How could anyone be dissatisfied with my daughter?" Such words came out of his mouth naturally.

Lin Qinghua thought about it and said, my fishing friend Lao Chen and I had agreed to go to Yangcheng, and he would take me fishing. He shouldn’t object to me.

Mother Lin applauded: "That's good, Nannan, what do you think? If you and Yuanguang have no objection, we can get this done as soon as possible.

As for property, you can get a property notarization before marriage to avoid giving Yuanguang the illusion that you are in a hurry to get married just because his company goes public.

Our family certainly doesn't seek any material things from him. We just think that it's not easy for the two of you to succeed in starting a business together from college to studying abroad. It's a rare fate that should be fulfilled.

His mother and I both mean this.”

Lin's mother was tough, and she was also worried that things would change if they were delayed for too long, so she wanted to settle it as soon as possible. Lin Qinghua naturally would not refute, and he was happy with it.

Lin Jia held her forehead with her hand. She didn’t want to get married. Even now, she still didn’t want to. She thought maintaining the status quo was good enough. Why should she get married?

Marriage is putting shackles on yourself.

The problem is that if you say something like this you will be scolded to death.

"Okay, Mom and Dad, don't worry about me. I know my own pace." Lin Jia dealt with it casually.

Lin's mother obviously didn't want her to get away with it this way: "Then you go back and discuss it with Yuanguang today. It would be best if both sets of parents are in Shenhai this time, so that ceremonies like engagement can be held directly. It's very convenient for our relatives to come to Shenhai, and it's also very convenient for Yuanguang's relatives to come and charter a plane." Lin's mother was very persistent.

Lin Jia resorted to procrastination: "I've been too busy lately, let's wait for a while, the company just went public recently, and Guangjia Aerospace costs 20 million US dollars to launch a rocket, I really don't have the energy to take care of these.

After a period of time."

"Boss, the data from SpaceX has been returned, and the probe has now entered the planned orbit.

The data monitoring the SpaceX launch process has also been synchronously transmitted back.

We will start the analysis later." Lin Tianmin, a researcher at Guangjia Aerospace and the interim head of the recyclable rocket group, had just graduated with a doctorate and left the aerospace institute before his probation period was over before he came to Guangjia Aerospace.

Currently, there is no big shot in the entire Guangjia Aerospace industry. All of them are masters and doctors who have just graduated.

It’s not that we didn’t recruit some people. Guangjia Aerospace’s treatment and vision can still attract some people, but it’s because those people are still in the desensitization period.

They poached the core R&D personnel of the Long March 9 from the Institute of Aerospace. The desensitization period alone started from one year, and it has not yet been completed.

The rest of the people are similar, because Light Armor Aerospace only wants elites, so the people who were recruited are either in the process of desensitization or are still struggling with their original units.

Your original company meant that the core project cannot be done without you, but it is not clear why you are only paid 200,000 yuan without you.

“Okay, our first phase of reusable rockets will definitely adopt the mainstream solution, using liquid oxygen/methane engines.

In the long run, my idea is to use solid-state batteries, and we want to use electricity as thrust.

In this way, our recycling ratio can be further reduced and costs can be significantly reduced.”

Fossil fuels are disposable and are useless once used up, but solid-state batteries can be recycled and can be recharged and used again.

The first stage and the reflow shield of the rocket can be recovered, and the recovery rate can be raised to 90%. The cost is estimated to be reduced to less than two million RMB.

After listening to this, Lin Tianmin asked in confusion: "Boss, some people have been talking about electric propulsion, including some satellites that use Hall electric propulsion to control direction.

But solid-state batteries are a bit far off.”

Chen Yuanguang shook his head: "No, solid-state batteries are about to be mass-produced, what are you thinking about.

Taiwan's ProLogium has already built its solid-state battery production line and is expected to be able to start mass 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 a systematic project needs to be broad-minded. He needs to know enough things to find the direction at the first time.

"Of course, at present we will mainly rely on fossil fuels. In about three years, we will start exploring electric thrust rockets," said Chen Yuanguang.

Lin Tianmin nodded: "Okay."

Chen Yuanguang continued, "I have seen the reusable rocket you designed, and it generally adopts a bare rod without booster design.

Then the grid rudder is used in the first stage to recover after launch.

In terms of engines, it is the same as the Falcon 9, adopting the strategy of connecting multiple liquid oxygen/methane engines in parallel, including two engines in parallel on the second stage.

In fact, I think this design is debatable.

There is no need to imitate the design of the starship for the time being.

How should I put it? Your overall design concept is very strange. It draws on the design concept of the Long March series of rockets, as well as the design concept of the Falcon and Starship.

We haven't launched it once yet. If you add two more engines to the second stage, it is easy for problems to occur during the vertical soft landing.

look"

Chen Yuanguang started to calculate on the whiteboard in front of his desk: "The final result is that the probability of something going wrong during a soft landing is more than 50%.

This plan is definitely not feasible.”

Lin Tianmin didn't say anything, he fell into deep thought, and at the same time he was a little shocked.

As they worked together for some time, or to be more precise, from the day of the interview, he knew that Chen Yuanguang really understood, and understood better than them, the PhDs in the aerospace field.

But he didn't expect to understand to this extent.

Just by looking at the design drawings, I can tell what's wrong with your design, and use theoretical calculations to prove that there is indeed a problem with your thinking.

This is more than one level higher than them.

You are also in your twenties, but you are so good at chemistry. This makes Lin Tianmin feel frustrated.

"Boss, I understand. I'll go back and think about it." Lin Tianmin couldn't help but sound a little disappointed.

Chen Yuanguang waved his hand and said, "Go ahead, this plan will definitely not work.

But it’s good enough to come up with such a solution for the first version.

We can learn from the ideas of Long March 9 and Starship, but at most we can learn from them. We need to go our own way.”

Chen Yuanguang knew that no matter what plan they came up with, there was a 99% chance that it would not be used.

In the end, we will definitely have to find a mature series of solutions from the future time and space to use.

But he still had to cultivate talents, and the hundreds of PhDs he recruited had to shoulder the heavy responsibility. For such a huge project, no matter how great he was, it was impossible for him to transfer all the technology by himself.

It's like after you are reborn, it is impossible to write Battle Through the Heavens by memorizing. The best way is to remember the story and then find a writer to complete and polish it.

　Slowly recovering over the weekend!
　　Weekends are definitely better.
