Siheyuan: The Era of Struggle.

Chapter 183 Mr. Guo’s “Three Questions”

When the four arrived at Mr. Guo's house, Mr. Qian went forward and knocked on the door. It was Mr. Guo's wife, Teacher Li, who opened the door.

When he saw Mr. Qian and Ms. Jiang, Teacher Li greeted them warmly. Although he was puzzled about Yang Ning and Hu Yinghong, he still nodded to them.

"Where is Lao Guo?" Mr. Qian asked Teacher Li as soon as he entered the door.

"What else can I do?" Mr. Li was being pulled by Ms. Jiang to introduce Hu Yinghong to her. After hearing Mr. Qian's question, he said helplessly.

"Since returning to his homeland and getting off the ship, he has been locking himself in his room except for necessary activities. He said he wanted to write down what he had memorized in his mind as soon as possible, so as to avoid forgetting it over time!"

"He should be in the study right now, fiddling with his stuff!"

"Then you guys go ahead and do your work. I'll take Yang Ning to find Lao Guo. You don't have to worry about us."

After hearing this, Mr. Qian took Yang Ning directly to the study, leaving the three women looking at each other, feeling a little amused and helpless for a moment.

"Old Guo, look who I brought to you?"

As he walked into the study, Mr. Qian said with a smile to a man who was sitting behind a desk and writing furiously.

Yang Ning also took a look at this time. The first impression of Mr. Guo was that he was thin, very thin, and looked very quiet.

But these cannot conceal the look in his eyes behind his glasses, which seems to be full of desire to explore all unknown things.

After Mr. Guo raised his head, he did not respond to Mr. Qian immediately, but looked at Yang Ning who was following behind Mr. Qian with his curious eyes.

The two of them looked at each other calmly for a while. Mr. Qian didn't care at first. He found a chair and sat down, smiling as he looked at the two people who were looking at each other.

After a while, Mr. Guo smiled and said, "You are the Yang Ning that Mr. Qian mentioned, right?"

"Hello, Mr. Guo, I am Yang Ning! As for whether it is the one Mr. Qian told you about, I don't know!"

Yang Ning also smiled, stretched out his hand and greeted Mr. Guo.

Now Yang Ning will not feel nervous about meeting these scientific giants. He has met many of them and can face this situation calmly.

"Haha~" Mr. Qian smiled after hearing what Yang Ning said, and introduced him to Mr. Guo: "This is Yang Ning, whom I just mentioned to you a few days ago. He has just joined my research project. How about it, do you want to join in?"

Looking at Mr. Qian's expression that said it would be a big loss if he didn't come, Yang Ning shook his head helplessly. He really guessed it right.

"What kind of research project is it?" After hearing this, Mr. Guo showed an interested expression and asked Yang Ning and Mr. Qian.

If Yang Ning's ability is really as important as Mr. Qian told him before, the higher-ups have agreed to let him join this project now, which means that this project is very difficult and very important to us.

As expected, this extremely challenging project aroused Mr. Guo's interest.

"How about researching a ballistic missile with a range of thousands of kilometers and an error of no more than 500 meters?" Mr. Qian looked at Mr. Guo expectantly.

At this time, Yang Ning also found a seat and sat down, watching the fight between the two brothers in silence.

"According to what you said, the performance of this missile should be able to reach the world average, but do we have such technical accumulation now?"

Mr. Guo thought for a while and asked the question that concerned him most.

"There should be no problem with manufacturing technology. Let me tell you one more thing. We are now able to produce three-axis CNC machine tools. There will be absolutely no problem with production."

Mr. Qian was afraid that he would not believe it, so he pointed at Yang Ning and said to him: "If you don't believe me, ask Yang Ning. He also participated in the development of that machine tool!"

Seeing the two people looking at him, Yang Ning shook his head: "Mr. Qian's information is outdated. With the experience of developing CNC milling machines, we have successively mastered the technology of other CNC machine tools during this period. It is said that we have already started to develop CNC machining centers!"

Speaking of this, Yang Ning had to admire our scientific researchers during this period.

Relying on the little knowledge of CNC machine tools that Yang Ningzhi taught at his alma mater a few years ago and the experience in manufacturing three-drawing CNC milling machines, they were able to achieve such results through their own exploration, allowing our machine tools to catch up with the world's advanced level to some extent.

"Are these true?" Mr. Qian and Mr. Guo asked in surprise after hearing the news revealed by Yang Ning.

"It's true. Except for the milling machine, we have only developed prototypes of other CNC machine tools. It will take some time before they can go into mass production." Yang Ning explained quickly when he saw them like this.

"That's not bad, it's enough for producing test bombs!"

Mr. Qian and Mr. Guo were not disappointed after hearing Yang Ning's words. Instead, they nodded happily.

It turns out that when they were in the United States, as long as they proposed the material parts with certain performance, the United States' industrial capacity would be able to quickly produce qualified products.

When he first returned to China, he was still worried about whether our industrial level could meet these requirements. However, after returning to China and conducting an inspection across the country, Qian Sheng felt that our production level at that time had far exceeded his expectations. He did not expect that there would be surprises.

"What about materials?" Industrial processing technology is not a problem, but materials are also important, so Mr. Guo continued to ask. After all, rockets and missiles, especially engines, have very high requirements for high temperature resistance and corrosion resistance of materials.

"I remember that Big Brother's R1200 with a range of 3 kilometers was developed based on R2, right?" Mr. Qian did not directly answer Mr. Guo's question, but looked at Yang Ning and asked.

"That's right!" Yang Ning nodded and said.

"Then can we produce materials with similar performance to R2?" Mr. Qian continued to ask.

The reason why Mr. Qian asked Yang Ning is that no one knows the development of our technology better than Yang Ning.

Yang Ning thought about it for a while, and finally shook his head helplessly.

If we can produce high-temperature resistant materials with this kind of performance, then we can modify the aircraft engines sent by Fengfei before and directly solve the engine problems of our dual-class fighters.

Although missile engines do not need to be able to work stably at high temperatures for a long time like aircraft engines.

However, if you want to push the terminal speed of the missile to Mach 2 to 2 (the speed of Big Brother's R4 missile has not been found, so you can only refer to the V maximum speed of Mach ), the requirements for the engine are still very high.

"It's not possible at the moment. To meet this requirement, the temperature in front of the wheel needs to reach over 1000°C, and we don't have any high-temperature resistant materials yet."

Just when Mr. Qian and Mr. Guo were both disappointed, Yang Ning suddenly said, "Give us some time. We will try our best to develop this material before you finish the design."

In the future, our aviation engines and aerospace engines will all be dependent on high-temperature resistant materials.

In this case, we might as well take advantage of this opportunity, combined with some knowledge from the Internet in later generations, to solve the problem of high-temperature resistant materials.

The specific formulas for high-temperature resistant materials for aerospace engines cannot be found on the Internet, as they are all confidential information of various countries.

However, information about the production equipment and production processes of these materials, as well as alloy types and crystal structures, can be found online.

When the J-20 took off later, in order to argue with netizens whether its engine was domestically produced or from Big Goose, Yang Ning searched for information on the internet.

"Ha, I almost forgot you're an expert in metallurgy!"

Mr. Qian laughed after hearing Yang Ning's assurance, and then a relaxed expression appeared on his face.

This confused Mr. Guo, and he wondered why his senior brother had so much confidence in Yang Ning.

"Will we make it in time?" he asked worriedly.

“Haha~” Seeing Mr. Guo’s expression, Mr. Qian smiled and said, “Don’t worry, as long as we match him with someone else, there will be absolutely no problem.”

Then he looked at Yang Ning and asked, "Are you still cooperating with Mr. Ye this time?"

Seeing this, Yang Ning said helplessly: "I don't know the others either?"

"It's settled!" Mr. Qian was relieved when he learned that Yang Ning would still go to Mr. Ye.

In fact, Yang Ning himself didn’t know that, in a small circle, he and Mr. Ye had already been called the golden partners in the metallurgical industry.

From the initial pure oxygen top blowing, to the later special steel for submarines, to the most recent titanium alloy, this pair of partners not only succeeded every time, but also did so in a very short time.

It’s no wonder that Mr. Qian felt that the matter was settled after hearing that Yang Ning still planned to cooperate with Mr. Ye.

You have to know that in the previous projects, both Yang Ning and Mr. Ye were able to develop them so quickly when we had no experience or foundation.

Although we are still relatively backward in the field of aerospace engine materials, we do have no foundation at all.

After all, Big Brother has supported us with this technology before, but the performance was not up to the standards of our missile!

"Okay!" Seeing that his senior brother had so much confidence in Yang Ning, Mr. Guo assumed that there would be no problem with the materials.

So he continued to ask: "Where are the manpower? It's impossible that there are only three of us on this project, right?"

Mr. Qian now felt a little guilty. If we really go by the standards of American scientific researchers, then are there only three of them?

As for the students he is teaching now, how much can they learn in just a few months?
However, in order to trick Mr. Guo, no, to recruit him into this research project, Mr. Qian said calmly, "How could it be just the three of us? We have already arranged more than a hundred relevant talents, and they are just waiting for you!"

Yang Ning almost laughed out loud when he heard this.

But suddenly he felt sad again.

Although I know that it takes time to cultivate our own talents, when I saw Mr. Qian looking around to develop our own missiles as soon as possible, I realized that what we are doing now is far from enough and we still have a long way to go!
