When I am reborn, I just want to be a top student

Yang Anchao showed a trace of emotion on his face, and couldn't help but say: "What a nostalgic youth. When I was the same age as you, I was far from your current achievements, but the passion for scientific research was exactly the same."

"To be honest, I have rarely seen young people, especially those of your age, who are so passionate about scientific research."

"There is someone to take over!"

Hearing what Yang Anchao said, Wang Donglai smiled and said, "Chief Engineer Yang, you are joking. Our country is so big, with such a huge population base, there are all kinds of people, including those who are eager to make a living, and naturally there are also those who work hard and devote themselves to their work."

"As for which of the two types of people are more numerous, judging from the development of our country over the years, it is obvious that we are more of the old workhorses."

"I agree with Chief Engineer Yang that there will be successors, but I think the most important thing is the hardworking and diligent Chinese talents."

Wang Donglai did not get carried away by Chief Engineer Yang's praise, and he elevated the situation to a higher level with just a few words.

Upon hearing this, Yang Anchao pointed at Wang Donglai and said with a hint of amusement: "I'm not talking to you on behalf of my superiors. Why are you so nervous? Why do you have to answer like that? There's no one else here!"

Hearing what Yang Anchao said, Wang Donglai said very seriously: "Chief Engineer Yang, what I just said came from my heart. I really believe it."

“Although there are some extremely outstanding heroes in every era, I still believe more in the people’s view of history.”

"Whether there are outsiders or not, whether I am facing an individual or an organization, I will answer like this."

This time, Yang Anchao was really shocked.

He really didn't expect that Wang Donglai would have such an idea.

"It's so hard to meet you, so let's not talk about the differences between the heroic and people's perspectives of history, but your private rocket company. I heard that your company is poaching people from various research institutes of the aerospace group, and the starting salary is three times the salary."

"It's so big that the news has reached me. Tell me the truth, what are you planning to do?"

When he said this, Yang Anchao's expression became serious.

"Although our country's aerospace technology is not the most advanced in the world, it has broken through the Western blockade in many areas and has become the world's number one."

"If it's just a small-scale poaching, it wouldn't be a big deal, but I heard that Galaxy Technology's move is very big, and they want to poach quite a few people this time."

"Some areas are highly sensitive and we must not only prevent technology leaks, but also prevent spies from stealing secrets."

Yang Anchao did not try to be mysterious with Wang Donglai, but made things clear directly, fearing that Wang Donglai would not understand the secret.

However, Wang Donglai did not look surprised at all.

Instead, he nodded very seriously and said, "Chief Engineer Yang, I understand what you mean."

"I set up a private space rocket launch company just to satisfy my own desire to go to space. At the same time, I am also echoing the country's call to drive private capital into high-tech fields and promote technological development."

"As for the technology leak, I am also very clear about this. I have set rules for the company and will not violate laws and regulations. I would rather go slow."

"I have also thought about the researchers I recruited from various research institutes. I am not looking at the senior executives, but rather the mid-level technical personnel, including welders, designers, etc., not all of them are engineers and researchers."

"Galaxy Technology Space Rocket Company's development path is the same as Bald Eagle's SpaceX, which is to follow a commercial approach."

"We will develop the technology we can develop ourselves, and we will buy the technology we cannot develop ourselves, or pay for the license. We will not infringe on the technology patents of the aerospace group, nor will we covet them and do something stupid."

In fact, Yang Anchao didn't think that Wang Donglai would do such a stupid thing. After all, in terms of academic status, Wang Donglai is already the youngest academician in the country. In terms of wealth, Galaxy Technology has a market value of hundreds of billions and he has made a lot of money.

No matter how you look at it, there is no reason to do this.

However, aerospace technology is of great importance, so Yang Anchao still said it clearly to be on the safe side.

"It's good that you understand this. Don't blame the organization for being sensitive. After all, we are developing so fast, and some foreign forces have never given up on interfering with our operations. They use all kinds of methods, and many people have been arrested over the years. So don't have any other ideas."

Yang Anchao was also worried that Wang Donglai might feel rebellious or uncomfortable because of this, so he started to explain.

"Chief Engineer Yang, I understand that such measures should be taken in such an important area. I completely understand that."

Hearing this, Yang Anchao felt relieved immediately. However, before he could completely relax, Wang Donglai's words brought him back to his senses.

"However, I still have some small doubts."

"Does the Aerospace Corporation really need more than 700,000 people?"

Yang Anchao showed a bitter smile on his face, but it was fleeting, and he explained: "Seven hundred thousand aerospace personnel, this includes all the people working in this field. A large part of them are logistics personnel, and there are not many core people."

Wang Donglai did not stop there, but continued: "Chief Engineer Yang, I am also the founder of a company with tens of thousands of people. I am very clear about this aspect."

"Some things are just like this. There is not much we can do. We just need to do our part and do research well."

Yang Anchao looked at Wang Donglai and reminded him meaningfully.

"Chief Engineer Yang, what you said does make sense, but I still say that I am still so young and have a lot of room for trial and error. There are some things I want to try to change."

"Research is research, but more people are sitting in offices than in labs, and the salaries are the same."

“I don’t think this situation is reasonable.”

"I want to try and see if using the concepts of private enterprises to research space rocket technology can bring about changes and produce results."

"If the results are not out, just think of it as a daydream. But if the results are out, the right and wrong will be clear."

Wang Donglai's voice was calm, but his tone was firm.

Hearing Wang Donglai's firm determination, Yang Anchao sighed inwardly.

"I know you young people always have all kinds of ideas."

"This kind of thing has no benefits, but offends people, so only young people like you would do it."

"Ugh!"

Yang Anchao sighed and said helplessly.

"Chief Engineer Yang, it is precisely because we are young that we have to do this. If we don't dare to do something courageous when we are young, we will definitely not do it when we are older."

"What about the golden finger igniter, what about the master craftsman carving explosives with his bare hands? We have entered the 21st century, and they are still using these backward methods. These situations should have been changed long ago."

When Wang Dong talked about this, his emotions fluctuated a little and he seemed quite angry.

"Actually, this is for both publicity and confidentiality," Yang Anchao explained with some lack of confidence.

"Chief Engineer Yang, I don't have any other intentions. I just think that this situation shouldn't happen."

Wang Donglai said in a serious tone.

After a moment of silence, Yang Anchao did not continue the conversation, but abruptly changed the subject.

"I have already explained why I came here, now it's your turn."

"Tell me, what's the matter with you?"

Wang Donglai smiled again and said, "Chief Engineer Yang, I am here for something. I want to find a research institute to study for a while. After all, I don't know much about this area. Most of it is from paper."

"And you are an expert in this field, so I wanted you to recommend something to me."

Hearing Wang Donglai say this, Yang Anchao's eyes moved, and after a little thought, he said, "It is indeed a good thing to go and investigate and learn. With your learning ability, you can learn some real things."

"But I have to ask first, where do you plan to start, or which area do you plan to focus your energy on?"

"Is it the control system, or the rocket engine, or maybe..."

Before Yang Anchao finished speaking, Wang Donglai gave his answer.

"Chief Engineer Yang, I am currently reading papers and materials on rocket engines and would like to start from this aspect."

"After all, the rocket engine is the heart of the rocket and is more challenging!"

Yang Anchao nodded and said, "Okay, now that you have a direction, you don't have many choices."

"The Sixth Academy of Aerospace and the Fourth Academy of Aerospace, one is a liquid rocket engine and the other is a solid rocket engine. Both are in Tangdu City. It's up to you to choose."

When he said this, Yang Anchao suddenly seemed to think of something.

He narrowed his eyes slightly, looked at Wang Donglai and said, "You must know the news about the Sixth and Fourth Hospitals, but you still came to me, so there must be something else. Let me think about it."

After just a moment, Yang Anchao said with certainty: "With your achievements and fame, if it is just a simple inspection and study, there will be no problem at all. Even if there are problems, Tang City can help you solve them."

"Then, there is only one possibility left. You want to participate in some core projects!"

Yang Anchao was naturally not a stupid person. He reacted in just a moment.

Wang Donglai saw that Yang Anchao had guessed it, so he did not hide it and said, "Chief Engineer Yang is indeed very discerning. I did join a cutting-edge team to observe and learn."

Yang Anchao really appreciated this frankness and directness, and a smile appeared on his face.

"Okay, since you've said so, I'll risk my reputation to help you get this done."

"I remember that the Sixth Hospital seems to have a project. Let me contact them and let you know when things are done."

Yang Anchao did not agree directly, but with his status, accomplishing this was nothing.

As the chief designer of Shenzhou V, this is really a trivial matter.

Next.

The content of Wang Donglai and Yang Anchao's conversation focused on rockets, and all the information Wang Donglai had read during this period was not in vain.

Not only did he keep up with Yang Anchao's pace, but he was also able to come up with some unique insights from time to time, which allowed Yang Anchao to gain something as well.

Just like that, the two of them started chatting heartily.

……

As the core of the rocket, the rocket engine sounds extremely high-end, but from a purely technical point of view, it is not that mysterious or high-end.

Because engines have been around for so many years, chemical fuel engines are also the most mature technology at present.

However, when it comes to the rocket, the situation is different.

First of all, the thrust of the rocket engine must be large enough. With a weight of hundreds or even thousands of tons, the thrust of the engine must at least be enough to push the rocket up. In order to generate sufficient acceleration, a greater thrust is needed.

At present, the total thrust of the first stage of the Saturn V rocket, the most powerful moon landing rocket in human history, exceeds 3500 tons, and the thrust of some of Russia's heavy rockets has even reached 4000 tons.

Compared with domestic ones, the thrust is only a few hundred tons, and the gap is extremely obvious.

After thrust, the rocket engine is required to have strong explosive power.

Once a rocket takes off, it will be affected by the huge gravity and air resistance and consume a huge amount of fuel and energy, but it will eventually need to reach the first cosmic speed of 7.9 kilometers per second to orbit the earth. From a cost-effectiveness perspective, the rocket is required to enter the Earth's orbit as quickly as possible.

Still taking the Saturn V as an example, its first stage has a total weight of approximately 2290 tons, of which 2160 tons are fuel. The standard engine operating time is only 165 seconds, which means that the first stage of the Saturn V burns an average of 13.1 tons of fuel per second.

Taking a car that consumes 10 liters of fuel per 1 kilometers as an example, the energy consumed by a rocket engine in one second is enough for the car to travel 17.95 kilometers.

Secondly, it needs to be light enough, made of strong enough material, strong enough, have a reasonable overall design, precise control, and have certain stability requirements, etc.

And these are just the most basic requirements.

As humans have learned more about space, many space mission demands have emerged, requiring the use of more environmentally friendly and efficient fuels and reducing the demand for launch sites. This brings up a problem, which is that the design of rocket engines has become more difficult.

As a result, advanced ultra-cryogenic liquid rocket upper stages, multiple ignition reuse engines, variable thrust and even vector control engines, ion electric propulsion engines, and photon engines appeared.

Of course, there are also some nuclear-powered engines that are still on paper and exist only in the minds of designers.

Nuclear-powered engines are certainly powerful, but they require the solution of controlled nuclear fusion first.

After saying goodbye to Yang Anchao, Wang Donglai's mind was filled with all kinds of inspiration.

If these were some simple problems, given Wang Donglai's current condition, they could probably be completely solved in no time.

But Wang Donglai's choice of challenge is not a simple issue.

Therefore, until the inspiration in Wang Donglai's mind disappeared, Wang Donglai did not completely solve the problem, but he also gained something. (End of this chapter)
