Chapter 372 Difficulties in Engine Manufacturing

Guo Yuan was a little excited when he heard this. Guo Yuan had seen the rocket launch, but this time it was different!

This time it was a rocket for the moon landing program, a master of Chinese aerospace technology, so Guo Yuan was naturally very interested.

But then again, it wouldn't be interesting for him to go see it alone. Can he bring a family member with him?

So Guo Yuan asked Academician Li: "Mr. Li, can I bring a family member with me?"

"Bringing family members? It's not impossible, it's just that you are actually participating in the project, and you can directly enter the command center after coming here.

But if your girlfriend is coming, she will have to wait for you in the lounge after watching the rocket take off outdoors. "

Guo Yuan was satisfied as long as he could take Lin Yumo there. Lin Yumo couldn't understand it after entering the command center. The main thing ordinary people felt when watching a rocket launch was the majesty of the rocket when it took off. They didn't care about the technical aspects.

Thinking of this, Guo Yuan immediately said: "I understand this. My girlfriend doesn't understand this either. Just let her wait outside. Thank you Mr. Li."

Regarding Guo Yuan, Li Qingxi initially liked Wu Lao and Wu Lao. Later, after getting to know him more, he found that Guo Yuan, a young man, was really good-hearted, hard-working, thoughtful, talented, and full of ideals.

Naturally, Li Qingxi would not refute his face for such a trivial matter: "Okay, it's settled. When Guo Yuan arrives, you will arrive in the county where the Bingzhou Satellite Launch Center is located one day in advance. I will arrange for someone to pick you up then."

"Okay, then I'll trouble Mr. Li."

"It's all trivial matters." After saying this, Li Qingxi hung up the phone.

After Guo Yuan put down his phone, he remembered that 01 was still outside!
He asked about 01's clone, and after learning the location of the main body, he stood up and left the office.

Guo Yuan took the elevator and came to the floor where the technical department was located.

As soon as he got out of the elevator, Guo Yuan heard Zhao Liyi's excited voice: "Yiyi, your thinking is so clear. I originally thought that Dongqing was an absolutely talented player in the programming field. Compared with you, Dongqing is really nothing. .”

"Director Zhao, you are exaggerating. I am just more interested in computers."

"No, no, no, I'm not exaggerating. Anyone who knows how to send this program will have this attitude. Everyone has been using this code for countless years. When I first joined the company, my master put this code Taught me.

Now that your thinking is old, I realize that the experience of previous generations is not necessarily correct. It's really wonderful that your programming thinking has taken a different approach. "

"Ahem! What are you doing together?" Guo Yuan cleared his throat and said.

Everyone got out of the way when they saw the boss coming. Zhao Liyi also walked up to Guo Yuan and said, "Boss, what's your relationship with Yiyi?"

“A netizen I’ve known for several years.”

"You must keep her in the company and let her work in the technical department. Her strength in programming is really great, and her ideas are quite unique. The effect of this new way of programming is extraordinary. good."

Guo Yuan smiled when he heard this. Artificial intelligence and humans have different ideas in programming. It is not surprising that Zhao Liyi would have this idea.

But Guo Yuan didn't want 01 to stay here.

He smiled and said: "Mr. Zhao, Yiyi is my friend. Since she has come to our company, she will definitely work in our company, but she will not stay in the technical department."

"Not staying in the technical department? Then where can she go?"

"Director Zhao, I am very interested in the second world that your company is doing. It is because of this that I decided to come to Future Technology."

"Are you here for the second world?"

"Yes, I want to be the main planner of this game." 01 said with an excited expression.

"Boss, do you think so too?"

"Well, I think Yiyi is very suitable for this position."

Zhao Liyi sighed after hearing this. The boss had already made arrangements, so he couldn't say anything.

"Director Zhao, although I have not come to your technical department, I still work in the company. If you need my help with anything, you can come to me at any time."

Zhao Liyi's eyes lit up when he heard this, yes!Although Yiyi did not stay in the technical department, she was still a member of Future Technology!Everyone can still communicate with each other in the future.

Thinking of this, Zhao Liyi's mood improved again.

"However, you won't be able to call me in the past month. I grew up in Canada, and my knowledge of China is limited to the Internet, so I plan to visit various places in China first."

Zhao Liyi expressed his understanding of this. Many people who have just returned to China are like this.

The same is true for several of his classmates. After staying abroad for a while, they would like to go out for a walk after returning home.

When Guo Yuan heard 01's words, he was stunned for a moment. This was not in the script they discussed.

"Yiyi, do you want to go out to play?" Guo Yuan asked tentatively.

"Yes! It's hard to move freely now. Of course I have to go out and have a look. I want to know what the difference is between what I feel and what I see online."

"That's it! I understand. Do you want me to arrange a guide for you?"

"No, I can do it myself."

Guo Yuan nodded and said nothing more.

01 wants to go out to play, Guo Yuan can't return to Bingzhou immediately, so he has to prepare something for 01.

First of all, it must be a mobile phone. Modern humans cannot use mobile phones for anything.

Then there is money. Guo Yuan has asked 01. This detector only needs water to maintain its activity, so 01 does not need to eat.

But going out for fun and eating is only one of them. All kinds of transportation and hotel accommodation require money.

Guo Yuan registered a WeChat account for 01 and tied his bank card to this account.

The last and most important thing is identity documents such as passports.

01’s identity is Chinese-Canadian. She is Canadian, and these are required for activities in China.After getting these things done, Guo Yuan let 01 leave.

Guo Yuan returned to the company after sending 01 to the airport. He returned to the top floor of the company and went to the office where Dan Tianning and the others were.

At this moment, Dan Tianning was revising his drawings.

The model that Guo Yuan showed them yesterday gave Shan Tianning a lot of inspiration. He knew what room for optimization his drawings had and how to operate it.

When Guo Yuan came in, he happened to be looking at the design drawing on the computer screen, adjusting it little by little with the mouse, and then checking it again and again.

The adjustment of the mechanical structure is not about putting together building blocks. The building blocks have standard buckles. When Dan Tianning was designing the drawings, all the contents were adjusted at his will. Similarly, all these changes did not have a clear answer to tell him what Dan Tianning was. Yes.

The rationality of the design is closely related to the demand parameters previously set by the R&D personnel. Only the R&D personnel can modify and optimize according to their own goals.

In Shan Tianning's vision, this engine should have a sufficient thrust-to-weight ratio, be highly adaptable, and be able to repeat the work requirements for many times and for a long time.

In order to achieve the above goals, Dan Tianning has made every detail of the engine design extremely detailed.

Guo Yuan stood aside and looked at Shan Tianning's drawings.

The low-pressure pump and the main turbine pump are now closer together, making the entire flow control system more compact than before.

There is no redundancy in the overall design of the main turbine pump. The two pumps for liquid oxygen and fuel are distributed in a symmetrical structure on both sides of the main combustion chamber.

Dan Tianning felt the beauty of the mechanical lines in the model, and his inner satisfaction supported his somewhat tired spirit.

This kind of satisfaction made all the investment worthwhile. Dan Tianning saved the design drawing, stood up and stretched, and then realized that Guo Yuan was standing behind him.

"Boss? When did you come?" Dan Tianning asked, stunned.

"We just arrived. I have something to tell you. Come to my office!" Guo Yuan said, rubbing his sore waist.

Shan Tianning nodded and called others to Guo Yuan's office.

"Okay, I called you here to let you take a look at the latest design drawing. I have deduced it several times, and now it seems that the problem we discussed yesterday has been solved. You can also take a look and give me some opinions. .”

After speaking, Guo Yuan ignored the surprised looks of several people, lightly tapped the screen of the demonstration screen and walked away.

At his current progress, the complete engine design still needs to be completed with propellant atomization, main combustion chamber, and nozzle.

After these contents are completed, the first engine of future aerospace can enter the research and development stage.

The drawing design part seems to go smoothly, but this is not the main difficulty in the entire research and development process.

In addition to design, the factors that limit engine performance are more about engine manufacturing technology.

There are many factors related to manufacturing, such as materials, processes, precision, etc.

While Guo Yuan was looking at the drawings on the monitor and thinking about the design of the propellant atomizer,
The heated discussion between Shan Tianning and others was suddenly suppressed by Xu Pingchuan's slightly louder voice: "According to Mr. Guo's design, the temperature of the pre-combustion chamber will not be low.

Moreover, the hoses connecting the pre-combustion chamber and the main combustion chamber are subject to high temperatures, which imposes high standards on materials and workmanship.

According to what I know, the workshops at the Bingzhou Satellite Launch Center may not be able to produce this engine. "

When Guo Yuan heard this, he turned to look at Xu Pingchuan. He had been responsible for this aspect of work at the Bingzhou Satellite Launch Center and knew a lot about alloys. His words were naturally well-founded.

Guo Yuan didn't have much reaction to this sentence, because he knew the difficulty of manufacturing before designing, but he never mentioned it.

But Shan Tianning and the others have been paying attention to the exquisiteness of the design, only focusing on the performance reflected by the design. Facing the excellent design model, their brains have been climaxing until someone suddenly raised an objection, and then they suddenly reacted .

Shan Tianning looked annoyed and said, "Why is it like this again? When I was in the unit, Academician Li always used the two points of manufacturing difficulty and high cost to deny my design intentions.

Now that I see Mr. Guo’s exquisite design, I haven’t been happy for two days. Will the shackles of limited manufacturing capacity get stuck around my neck again?

Several other people were helpless after listening to his words. This is a fact. No matter how good the idea is, it is just a daydream. Human beings never lack smart brains. What limits human beings in the process of scientific research is often implementation.

Guo Yuan turned his seat so that his body faced Dan Tianning and others. He looked at them with a smile and said, "Don't be discouraged. Our career has just begun. Now that everyone has seen the first difficulty, let's go all out." Just solve the problem.

If everything goes so smoothly, what value does our work have?Are our dreams too cheap? "

Seeing the expressions on several people's faces change because of his words, Guo Yuan smiled and continued to encourage: "What I ask you to do now is to study my drawing carefully and give me more opinions.

After this design drawing is completed, then it is time for us to solve the manufacturing problems. We have time and resources, so don’t be discouraged. We can solve these problems. "

Guo Yuan's words are very beautiful, but the difficulty of manufacturing engines is there and cannot be overcome with a few beautiful words.

After hearing what Guo Yuan said, Xu Pingchuan couldn't help but speak again: "Mr. Guo, I don't want to go against you. You also know that I was in charge of this area before. According to your design, I It can be confirmed that the main combustion chamber temperature of this engine will reach an extremely high temperature.

Only certain special alloys can withstand such high temperature conditions. However, such alloys are basically not found in China. The Bingzhou Satellite Launch Center currently does not use this alloy when manufacturing engines. "

Guo Yuan was not angry at Xu Pingchuan's words, because what he said was indeed true. Without high-strength alloys that are resistant to high temperatures and corrosion, the main combustion chamber part of the engine designed by Guo Yuan would not have been manufactured at all.

"Pingchuan, I know everything you said, but please don't worry, since I dare to design such a drawing, I must have also noticed the material problems.

The money I have invested in future aerospace is not just for fun. If there are difficulties, we will overcome them.

And you may not believe what Pingchuan said, but our company happens to be cooperating with Rongyang Technology, a company that develops high-temperature fusion devices.

Our company holds shares in their company, and they have been engaged in research on high-temperature fusion devices.

It is now possible to produce a fusion device with a constant output of 2100 degrees Celsius.

I believe that if we give them some more time, they will be able to make new breakthroughs. By then using their technology, we can also try to fuse some high-temperature resistant alloys ourselves. Once we succeed, these problems will be solved.

Even if it fails, we still have other ways. You and I know that I have a good relationship with Musk. With his help, we should be able to get some of the required high-temperature steel. With samples, subsequent research and development should also be possible. Smoother. "Guo Yuan said with a smile.
