There was a hint of emotion on Yang Anchao's face, and he couldn't help but said: "What a nostalgic youth. When I was the same age as you, I was far from your current achievements, but my love for scientific research was exactly the same. ”
“To be honest, I have rarely seen young people, especially at your age, who are so passionate about scientific research.”
“There are people who will succeed you. !”
Hearing what Yang Anchao said, Wang Donglai said with a smile: "General Master Yang is joking. Our country is so big and with such a huge population base, there will be all kinds of people. There are villains who are enthusiastic about camping. Naturally, There are also old scalpers who work hard. "
"As for whether there are more of the two types of people, judging from the development of our country over the years, it is obvious that we are more old scalpers."
"General Master Yang said that there will be successors. I completely agree with it, but I think it is the struggle and hard work of all the country's talents that are the main thing."
Wang Donglai did not get carried away because of General Master Yang's praise. Two sentences sublimated the pattern.
Hearing this, Yang Anchao pointed at Wang Donglai and said with a smile: "I am not talking to you on behalf of my superiors. Why are you nervous? As for answering like this, there are no outsiders here!"
Hearing what Yang Anchao said, Wang Donglai was extremely He said seriously: "General Master Yang, what I just said comes from my heart. I really think so."
"Although there are some extremely outstanding people in every era. A heroic figure, but I also firmly believe 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 this way."
This time, Yang Anchao was really shocked.
He really didn't expect Wang Donglai to have such an idea.
“It’s hard to meet you once. Let’s not talk about the differences between the heroic view of history and the people’s view of history. Let’s talk about your private rocket company. I heard that your company is present in major research institutes of the aerospace group. Recruiting people starts with three times the salary.”
“The big battle has reached me. Tell me the truth here, what are you going 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 fields and become the number one in the world.”
“If it is only a small Poaching people on a large scale is nothing, but I heard that Galaxy Technology’s actions are very ambitious. There are many people who want to be poached at one time. "
"Some areas are in high-risk and sensitive areas. It is not only necessary to prevent technical leaks, but also to prevent spies from stealing secrets."
Yang Anchao did not play tricks with Wang Donglai. Instead, he explained the words directly, for fear that Wang Donglai would not understand the mystery.
However, Wang Donglai was not very surprised.
But he nodded extremely seriously and said: "General Master Yang, I understand what you mean."
"The establishment of a private space rocket launch company is just to satisfy my own desire to go to heaven. , and at the same time, it is echoing the country’s call to drive private capital into high-tech fields and promote technological development.”
“As for technology leaks. , 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 also have researchers poached from major research institutes. After thinking about it, I focused not on those at the top, but on the middle-level technicians, including welders, designers, etc., not all engineers and researchers.”
“The development route of Galaxy Technology Space Rocket Company is the same as Bald Eagle’s SpaceX, which is commercialized.” Spending money to buy a license will not infringe on the aerospace group’s technology He won’t covet technology patents and do stupid things.”
Yang Anchao actually doesn’t think Wang Donglai would do such stupid things. After all, in terms of academic status, Wang Donglai is already the youngest academician in the country, and in terms of wealth, Galaxy. The market value of technology is hundreds of billions, making a lot of money.
No matter how you look at it, there is no reason to do this.
However, aerospace technology is very important, so Yang Anchao still said this clearly for the sake of insurance.
"It's good that you understand this. Don't blame the organization for being a little sensitive. After all, we are developing so fast. Some foreign forces have never given up on adding sand. They have various methods. People who have been arrested over the years have also It’s not a minority, so don’t have any other ideas.”
Yang Anchao was also worried that Wang Donglai would feel rebellious or uncomfortable because of such things, so he explained immediately.
"General Master Yang, I understand that such an important field should have such measures, I completely understand."
Hearing this, Yang Anchao felt relieved. However, before this tone completely relaxed, Wang Donglai mentioned it again.
“However, I still have a little doubt.”
"Does the aerospace group really need more than 700,000 people?"
A wry smile appeared on Yang Anchao's face, but it passed quickly, and he explained aloud: "Seven hundred thousand astronauts, This includes all people working in this field, a large part of them are logistics personnel, and there are not many people who are really core."
Wang Donglai did not. He stopped there, but continued: "General Master Yang, I am also the founder of a company with tens of thousands of people, and I am very clear about this."
"Some things are like this, and what we can do Not much, just do what you should do, and doing research is the serious thing."
Yang Anchao looked at Wang Donglai and reminded him with some meaning.
"General Master Yang, what you said does make sense, but I still say the same thing. I am still so young and there is still a lot of room for trial and error. There are some things I want to try and change."
"Doing research is just doing research. As a result, there are more people sitting in offices than in laboratories, and the same is true for wages."
"In this situation, I don’t think it’s reasonable.”
“I want to see if we can make changes and achieve results if we use the concepts of private enterprises to study space rocket technology.”
"If the results don't come out, just think of it as a daydream. But if the results come out, right and wrong will naturally be clear."
Wang Donglai's voice was calm, but his tone was firm.
Hearing Wang Donglai’s firm thoughts, Yang Anchao sighed inwardly.
“I know you young people always have all kinds of ideas.”
“There is no benefit in doing this kind of thing, but it will offend people, and you are young. People may do it.”
“Oh!”
Yang Anchao sighed and said helplessly.
"General Master Yang, it is precisely because we are young that we have to do this. If you don't dare to do something courageous when you are young, then you will not do it when you are older. "
"What a golden finger igniter? , The craftsmen of big countries carving explosives with their bare hands have entered the 21st century and are still using these backward methods. These situations should have been changed long ago."
When Wang Donglai talked about this, his emotions also changed. A little fluctuation, looking quite angry.
“Actually, this is both for publicity and confidentiality.” Yang Anchao explained with some lack of confidence.
"General Master Yang, I have no other intention. I just think that this situation should not happen."
Wang Donglai said in a serious tone.
After a moment of silence, Yang Anchao did not continue the conversation on this topic, but suddenly changed the topic.
“I’ve already told you why I’m here, now it’s your turn.”
"Tell me, what's the matter with you?"
A smile reappeared on Wang Donglai's face and he said aloud: "General Master Yang, I do have something to do here this time. I want to find a research institute. After studying for a period of time, I don’t know much about this aspect. Most of it is from paper.”
“And you are a big boss in this field, so I thought about it. Can you recommend it to me? "
Hearing what Wang Donglai said, Yang Anchao's eyes moved, he thought for a moment, and then said: "It is indeed a good thing to go and study. With your learning ability, you can learn something. Real thing.”
“But I have to ask first, where are you going to start, or what area are you going to focus your energy on?”
"Is it the control system, or the rocket engine, or..."
Wang Donglai gave his own answer before Yang Anchao finished speaking.
"General Master Yang, I am currently reading papers and information on rocket engines, and want to start from this aspect."
"After all, rocket engines are the heart of rockets, and there are more Challenge value!"
Yang Anchao nodded and said: "Okay, now that you have a direction, there are not many choices."
"The Sixth Aerospace Academy and the Fourth Aerospace Academy, one is a liquid rocket engine and the other is a solid rocket engine. Both of them are in Tangdu City. It's up to you how you choose."
When it comes to this. , Yang Anchao suddenly seemed to have thought of something.
He narrowed his eyes slightly, looked at Wang Donglai and said loudly: "You must know the news about the Sixth and Fourth Hospitals, but if you still come to me, then there must be other things that make me think. Just a moment.”
After just a moment, Yang Anchao said with certainty: "With your achievements and fame, if it is just a simple inspection and study without any problems, even if there are problems, Tangdu City can help you solve them."
"Then, there is only one possibility left. You want to participate in some more core projects!”
Yang An was not a fool, he just reacted in a moment.
Wang Donglai saw that Yang Anchao had guessed it, so he did not hide it and said, "General Master Yang is indeed very discerning. I am indeed joining a frontier team to investigate and learn."
This Yang Anchao appreciated his frankness and directness, and a smile appeared on his face.
“Okay, since you have said it, I will put on my old face and help you get this matter done.”
“I remember there seems to be a project in the Sixth Academy, etc. I’ll get in touch and let you know once the matter is settled.”
Yang Anchao did not directly agree, but with his status, it was nothing at all to accomplish such a thing.
As the chief designer of Shenzhou V, this matter is really a trivial matter.
Next.
The chat between Wang Donglai and Yang Anchao focused on the Rockets. The information Wang Donglai read during this period was not in vain.
Not only did he keep up with Yang Anchao's rhythm, but he also came up with some unique insights from time to time, which made Yang Anchao gain something.
In this way, the two started chatting heartily.
......
As the core of the rocket, the rocket engine sounds extremely high-end. In fact, from a purely technical perspective, it is not very mysterious and high-end.
Because engines have been around for too many years, chemical fuel engines are currently the most mature technology.
However, when it comes to the rocket, the situation is different.
The first is that the thrust of the rocket engine must be large enough, which can easily weigh hundreds or even thousands of tons. The thrust of the engine must at least push the rocket up. In order to generate sufficient acceleration, the thrust must be greater.
Currently, the total thrust of the first stage of the Saturn V rocket, the most powerful moon landing rocket in human history, exceeds 3,500 tons, and the thrust of some of Mao Xiong’s heavy-duty rockets even reaches the 4,000-ton level.
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 the rocket takes off, it will be affected by huge gravity and air resistance, consuming a huge amount of fuel and energy, but it will eventually need to reach the first cosmic speed of 7.9 kilometers/second before it can orbit the earth. In terms of cost performance, the rocket is required to enter the earth's orbit as quickly as possible.
Still on the Saturn V, its first stage weighs approximately 2,290 tons, of which 2,160 tons are fuel. The standard engine working 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.
Converted to a car with a fuel consumption of 10 liters per 100 kilometers, for example, the energy consumed by the rocket engine in one second is enough to allow a car to travel 179,500 kilometers.
Secondly, it needs to be light enough, the material is strong enough, the strength is high enough, the overall design is reasonable, the control needs to be precise, stability is also required, etc.
And these are only the most basic requirements.
After humans have learned more about space, there have been many demands for space missions, which require the use of more environmentally friendly and efficient fuels, reducing the demand for launch sites, etc. This has brought about a problem, That is when rocket engine design becomes more difficult.
Since then, advanced ultra-low temperature liquid rocket upper stages, multiple ignition reuse engines, variable thrust and even vector control engines, ion electric propulsion engines, and photon engines have appeared.
Of course, there are also some nuclear power engines that are still on paper and only exist in the minds of designers.
Nuclear power engines are certainly powerful, but controllable nuclear fusion needs to be solved first.
After bidding farewell to Yang Anchao, Wang Donglai was filled with all kinds of inspirations.
If it is a simple problem, given Wang Donglai's current state, it may not take long to completely solve it.
But Wang Donglai's choice of challenge is not a simple question.
So, until the inspiration disappeared in Wang Donglai's mind, Wang Donglai did not completely solve the problem, but he also gained some gains. (End of this chapter)
