The world's richest man started by developing gutter oil

After hearing Han Chen's words, everyone present wondered if they heard it wrong.

"Did I hear it wrong or did the boss say something wrong? Can rockets be used again and again?"

"Aren't rockets disposable? How can this thing be used repeatedly?"

"It seems that the boss doesn't understand that the aerospace industry would make such funny remarks."

"You kid actually spoke out your feelings. Aren't you afraid that it will be heard by the boss? The salary in the institute is not as high as Deep Blue."

“Haha, our boss’s ideas are really fantastic.”

Most of the engineers in the audience felt that Han Chen's idea was whimsical.

Of course, some people also hold different views.

"I think what the boss said is not impossible. Just because we haven't thought about some things doesn't mean it can't be achieved. Repeated recycling is a kind of technological innovation. If we don't even have the heart to innovate, then we still have to What a crappy research.”

"I think this brother is right. Although the boss's idea is a bit wild, it does not mean that this technology cannot be realized."

"Actually, I think this technology is theoretically possible, but we have never thought that the rocket can be recycled."

"You don't want to think about why Deep Blue Group can develop so much in a few years. It's not because the engineers of Deep Blue Group dare to imagine. Otherwise, how could they develop technology that is even more advanced than that of Europeans and Americans."

"Yes, those of us who do research must dare to think and do, otherwise how can we create new technologies."

Soon the engineers in the audience realized the problem. Now the boss was holding a meeting for them. What they were talking about here was nothing. The scene fell silent in less than 5 seconds.

"I know that many people think that rockets that can be used repeatedly do not exist. The reason why you think so is because there is a problem with your thinking. You have always been learning foreign technology and you have always used foreign parameters. To evaluate something, this will cause your thinking to fall into a strange circle.

This strange circle makes you think that if foreigners can’t create something, why can we humans create such a thing?

The reason why Deep Blue Group can surpass foreigners in semiconductor technology is because our engineers dare to think and do, and dare to turn unrealistic things into reality.

In fact, the principle of recycling rockets is very simple. The only thing we lack is data to verify it. If we want to verify something, we can only do more tests.

Next, let’s watch a CG animation made using 3D technology according to my concept. I believe everyone will have a certain understanding of rocket recycling after watching this animation. "When Han Chen said this, a line of words appeared on the big screen behind him.

This animation was made by Han Chen based on his memory of the entire process of launching and recovering rockets from SpaceX.

Because the 3D effect of the Magic Eye Engine is too realistic, many people wonder whether this video was secretly filmed by Han Chen from a foreign rocket launch base.

"Isn't this a video of a foreign rocket launch?"

"Are you stupid? If foreigners had mastered this technology, they would have shown it off long ago."

"If foreign countries had this kind of technology, they would have shown it off long ago."

"This recycling idea seems to be really feasible."

"It turns out that rockets can also be recycled through brackets. The person who came up with this method is really a genius."

"Could this person be here with us? Who do you think this person is?"

"Don't tell me that this method seems to be feasible. The person who came up with this method has a really big brain."

15 minute later.

"Rocket recovery must first solve the problem of attitude control. The traditional method is to control the thruster to control the direction. It is extremely costly to control the rocket attitude in this way, and the rocket made by this method cannot be recovered.

My solution is to use a new way to control the attitude of the rocket.

You should have seen in the video that transparent gas is ejected from the rocket body. We use cold air propulsion to correct the arrow body. This technology I call cold air propulsion.

In addition, everyone should see the eight grid wings on the rocket body, which are used to assist the rocket in correcting the posture of the arrow body.

These two technologies can not only help us correct the arrow body when launching the rocket, but we can also use these two technologies to correct the arrow body when recovering.

The biggest problem here is the precise control algorithm. I think this should not be difficult for everyone here.

The second difficulty in rocket recovery is the re-ignitable engine. I think this problem is not difficult for everyone here. The third difficulty is the four deployable hydraulic buffer legs.

The last difficulty is the precise guidance system. That is, when the rocket returns, based on the rocket's current position, speed, attitude and other information, it can calculate the size and direction of the engine's thrust online in real time, and control the rocket to achieve precise landing.

I believe that the first few difficulties are nothing to you, and the last difficulty is the most difficult for you.

Because there are no ready-made parameters for how to accurately guide a rocket, you can only verify it with rigorous theoretical analysis and thousands of experiments.

I can't help you with theoretical analysis, but the company can support you with thousands of launch experiments. Of course, this does not mean that the experimental funds are unlimited. You must conduct rigorous demonstrations before doing experiments. Just fine.

Otherwise, let alone the Deep Blue Group, even the entire Chinese treasury would not be able to support your experiment.

However, we can give you a suggestion here, a suggestion to reduce rocket development and manufacturing costs. As long as everyone uses this technology well, mass-producing rockets will be as simple as mass-producing cars.

The technology I'm talking about is 3D printing technology. 3D printing technology can not only print engines, but even rocket bodies can be printed with 3D printing.

The 3D printing technology team company is already recruiting, and they will cooperate with you in researching recyclable rockets.

I have also told everyone about the research and development direction of recyclable rockets. Do you have any objections to what I said? "Han Chen asked, looking around at everyone present. At this time, the 243 engineers present were still thinking about what Han Chen just said. Their professional knowledge told them that what Han Chen said can be realized, and the person who can come up with this method is really a genius.

At this time, a middle-aged man in his fifties sitting at the front raised his hand. Although the man was only in his fifties, his temples were already white, and his head was covered with silver and black silk.

"Gong Yuan, tell me." Han Chen looked at the man and said.

The man's name is Yuan Zhengyang, a researcher directly hired by DeepBlue from the Aerospace Research Center. At the same time, Yuan Zhengyang is also the chief engineer of the Rocket R&D Department of DeepBlue Group. Yuan Zhengyang has participated in the research and development of many national space rockets.

"Mr. Han, I would like to ask which genius came up with this idea?" Yuan Zhengyang asked.

"What's wrong with me coming up with this idea?" Han Chen asked.

Everyone present was shocked when they heard that Han Chen came up with this idea. Han Chen's words made them feel that all the years of reading were in vain.

"Mr. Han also studied aerospace?" Yuan Zhengyang asked doubtfully.

"I majored in chemical engineering and minored in computer science. I like to think blindly, but I don't really think blindly. Every idea is proven. The most important thing for innovation is imagination. If you don't have enough imagination, , then you won’t be able to get out. When playing chess, you must jump out of the chessboard to watch chess.

When thinking, you must abandon your professional knowledge and theories, think about something from a common perspective, and then use professional knowledge to demonstrate whether it can be realized. Only in this way can you create new things.

I believe many of you here should know that the body of Deep Blue Car is made using integrated die-casting technology.

Do you want to know how Deep Blue came up with the idea of ​​using this technology? "Han Chen said.

Many people present shouted the word "think" in unison after hearing Han Chen's inquiry.

"From the day I decided to build a car, I started to study the information related to car building. If I didn't read it, I wouldn't know what to read next. After reading the relevant information, I realized that building a car is so complicated. A car body actually has 200 parts. Multiple parts.

At that time, I was wondering if there was a way to make the entire car body at once. After thinking about it for a long time, I couldn't figure out how to do it well, so I went to Tudou.com to watch videos to pass the time.

Coincidentally, I saw a video from a toy manufacturer. This toy manufacturer was promoting their toy car. The video also showed their production process. They made it through die-casting technology.

Seeing this, I also had an idea. Can a car be made in this way? As long as we make the die-casting machine bigger, can we die-cast the body?

I told our engineer about my idea, and our engineer told me that this method was feasible, so we contacted Li Jinlian and developed a die-casting machine, and the body of the Deep Blue Car was manufactured in this way.

In the same way, the cold-gas thrusters of recyclable rockets also came to my mind after watching videos of astronauts moving in outer space.

Since astronauts can control flight through the backpack jet system, can the rocket also be controlled in this way? Thinking of this, I asked some experts for consultation. The results given by the experts are that this control method is feasible. .

It’s just that no one has ever used this control method. Just because no one has used it doesn’t mean it’s not feasible. Since it’s feasible, why don’t we give it a try?
Including the idea of ​​using 3D printing technology to make rockets, I also came up with it after learning about how rockets are made.

A traditional engine consists of more than 1000 parts, and the accuracy of each part is also very high. If the accuracy is not suitable, it needs to be remade, which results in the manufacturing time of each part being very long and the manufacturing cost of each part is also very high.

In this case, can the rocket engine be manufactured like one-piece die-casting? The integrated engine does not need to worry about accuracy because they have been made into a whole.

It is impossible to cast a rocket engine using integrated die-casting, because the interior of the rocket engine is very complex and cannot be demolded after die-casting, and there is no other way to make the engine as a whole.

At this time, I thought of the technology that an alumnus of my college days mentioned. This technology is the 3D printing technology I just mentioned. When manufacturing with 3D printing, there is no need to consider the issue of mold release.

And the cost of 3D printing is definitely much cheaper than the cost of going to dozens or even hundreds of manufacturers to manufacture engines.

When we are in a desperate situation when thinking about a problem, it is better to think in a different way, or consult other people, maybe there will be unexpected gains. "Han Chen said.

After hearing Han Chen's words, some people felt that their thinking had broadened a lot, and some even began to reflect on whether their previous way of thinking about problems was wrong.

All roads lead to Rome. When you encounter a dead end, why not try to smash the wall of the dead end or climb over the wall.

Is it possible to break through the wall or climb over it which is the correct answer.

In fact, they have known this truth for a long time, but they have fallen into a strange circle after studying too much, and this strange circle makes them afraid to try.

Of course, in addition to this reason, another reason is that the cost of trial and error in their industry is too high.

Most people don't dare to try easily. A failure can cost hundreds of millions, sometimes hundreds of millions or even billions, which makes them have to be rigorous.

For people like them, being able to successfully launch a rocket is a success. As for recycling the rocket, they dare not even think about it, because the cost of trial and error in this industry is too high, and few people are willing to pay hundreds of millions or even It takes billions for them to try and make mistakes, but even a country would not dare to try it easily.

What's more, the commercial value of this industry has not yet been developed, and no one is willing to invest so much money in trial and error.

Only Max, a lunatic, and Han Chen, a man who traveled back from the future, are willing to invest money in this industry.

"Do you still have any questions? If there are no questions, then by the end of today's meeting, the general direction has been told to you. I hope to see your R&D results before the end of 15. In addition, your annual R&D expenses are 200 billion. ." Han Chen said.

Many people present took a breath after hearing Han Chen's words.

It is now the end of 2013, and there are only 15 years until the end of 2. The time given by Han Chen is too short.

But looking back and thinking about it, 2 years is not a short time. The rocket technology of this era is already very mature. They are just improving the original technology. As long as they do more experiments, they will definitely be able to make it.

What's more, Han Chen gives them 200 billion in R&D expenses every year. The cost of launching a rocket is about 5 million yuan. If they use a small rocket to test, it will cost up to 1-2 million. If they use 3D printing to produce the rocket, the cost will be even more. Low, maybe tens of millions can make a rocket.

In other words, the research cost of 200 billion is enough for them to launch hundreds of rockets in a year.

Thinking of this, everyone present is confident that the research results will be produced before the end of 15. (End of chapter)
