Siheyuan: The Era of Struggle.

Chapter 196 Shock Wave Tunnel (Subscription Request)
The turbulent situation in the outside world did not affect the old city at all. People still devoted themselves to the construction with full enthusiasm as usual.

"Mr. Qian, have you copied the engines of the two big firecrackers sent by Big Brother?"

At the Institute of Aeronautics and Astronautics, Yang Ning asked as he and the researchers drew the structural drawings of Big Brother's two large firecrackers based on the assembled parts.

Mr. Qian was also not far away at this time, calculating the aerodynamic layout of the missile based on these technical drawings. After hearing what Yang Ning said, he looked up at him and said with a smile: "After you and Mr. Ye solved the problem of high-temperature resistant materials, the factory below has already made the previously damaged parts. As long as the assembly is completed, we can continue the previous test run."

Then he looked at Yang Ning strangely and asked, "Why did you suddenly think of asking this?"

"Based on the design concept of Feng Fei's previous engine and combining it with the structural layout of the two big firecracker engines, I have designed a new missile engine. I just don't know if it will work?" As soon as Yang Ning finished drawing a blueprint, someone immediately took the drawing and checked it for errors based on the previous disassembly diagram.

"Oh?" Mr. Qian looked at Yang Ning in surprise after hearing what he said: "What do you mean?"

"I want to make this engine and compare it with the R2 engine to see if it can meet the range requirements of the missile we designed?"

"Do you have detailed drawings?" Mr. Qian asked excitedly after hearing Yang Ning's words.

He had previously discussed with Yang Ning about modifying our missile engine based on Fengfei's engine, but the drawings of that engine were soon taken back by the higher-ups, and he was also busy training missile talents, so he put the matter on hold. Unexpectedly, Yang Ning was still persisting, and it seemed that there was some progress.

"Yes, but I don't have it with me now."

It is just as Mr. Qian thought. After Yang Ning's continuous calculations during this period of time, the engine designed by Feng Fei can indeed be used as the basic version of our turbo engine. If we want a turbo engine with that kind of performance in the future, we only need to improve it based on that engine.

In the past few months, Yang Ning used all his remaining computing power to improve this engine. Finally, based on this engine and combining it with the engines of the previous two big firecrackers, he designed a new missile engine.

"Is the calculation okay?" asked Mr. Qian.

"The calculated result is correct, but this engine can no longer use ethanol as fuel, otherwise it will not meet the missile's range requirements." Yang Ning said with a smile.

"Mr. Qian, Engineer Yang, when you discuss this kind of thing in the future, can you please avoid us? If anything goes wrong, we can't afford it!"

At this time, a student taught by Mr. Qian saw that the two seemed to be about to continue talking, so he quickly stopped them.

"Uh~" Yang Ning was stunned for a moment, turned his head and saw that everyone else was intentionally or unintentionally staying away from him and Mr. Qian, as if they had heard nothing and knew nothing, and were busy with other things.

"Haha~" Mr. Qian smiled after seeing this situation and said to these young students: "You can participate in this project, which shows that you are all capable of withstanding the test. Since Comrade Yang Ning's engine design is part of this project, you have the right to know. Don't worry about anything. As long as you can learn something from it, this risk is worth it."

The reason why Yang Ning and Mr. Qian dare to talk about this here is because they both understand that although the current project is to study the two big firecrackers of Big Brother, it is also a way to train the people involved in this project and accumulate technology for the subsequent research of our missiles.

These students who are now studying with them will become the main force in the next missile research and development project. After all, we only have these missile technical talents here, who else can we rely on for the next missile research?

After listening to Mr. Qian's words, the students finally breathed a sigh of relief. Those who were able to participate in this project had all received confidentiality training before and knew what they could say and what they could not say.

But these two people are about to talk about the next project. Is this something they can listen to?
Now that Mr. Qian has said this, it means that they will also be involved in the next stage of new missile research and development. In this case, it’s okay to just listen.

Despite this, Yang Ning and Mr. Qian ended the topic and did not continue the conversation.

When it was time to get off work, Mr. Qian called Yang Ning and said, "Yang Ning, after dinner, bring the drawings to my house."

"Okay!" Yang Ning did not refuse after hearing this. After all, the engine he designed was just calculated by himself under the super brain mode. As for whether it met the requirements, he still needed Mr. Qian to check it.

After returning home and having dinner in the evening, Yang Ning went to Mr. Qian's house with the drawings of the missile engine he had designed earlier.

When he entered the room, he found that not only Mr. Qian, but also Mr. Guo, whom he had not seen for some time, was there.

After seeing Yang Ning, Mr. Guo waved at him repeatedly: "Yang Ning, come here quickly, I was just talking about you!"

"Oh?" Yang Ning found an empty seat and sat down. He looked at Mr. Guo and asked in confusion, "What did you say about me? You didn't say anything bad about me, did you?"

"You~" After hearing what Yang Ning said, Mr. Guo pointed at Yang Ning and said, "Am I that kind of person?"

"During this period, I led a few students to repair a wind tunnel. Unfortunately, the performance of this wind tunnel is not good. The wind it blows out barely exceeds the speed of sound. It also consumes a lot of energy, is expensive, and has a small caliber. It can barely blow a J-6 fighter jet, and is basically useless for missiles and future new fighter jets."

"So I planned to design a new wind tunnel using shock tube technology. One of the students heard about this design and proposed to use the shock wave and heat generated by the explosion of the mixed gas to replace the turbofan..."

"Hiss~" After hearing what Mr. Guo said, Yang Ning couldn't help but take a breath. Could the student Mr. Guo was talking about be Academician Yu, the father of our wind tunnel?
Oh, Academician Yu is still in his prime, only seven years older than Yang Ning, and not yet thirty years old.

According to the original history, he should indeed be studying at the Chinese Academy of Sciences now.

It was not USTC. At that time, we were trying to establish a graduate student system in the Chinese Academy of Sciences based on the model of our big brother. Academician Yu was pursuing a postdoctoral degree in fluid mechanics at the Chinese Academy of Sciences.

Of course, this system encountered many setbacks in its implementation and was ultimately short-lived.
