The expedition continues.

After all, up to now, what the Soviet Union has tried to sell to China is mainly the MiG-29 fighter, which has been exported to many countries, and in their eyes, it should have been sold to China.

It's just that the Chinese delegation did not look satisfied with the MiG-29, and after leaving the Mikoyan Design Bureau, the next place to inspect was the Central Fluid Institute.

On December 1, 1918, H-E. Zhukovsky, a well-known veteran of Soviet aviation and known as the father of Soviet aviation, proposed to the Red Soviets, and Lenin, the leader of the Soviets at that time, personally signed the plan of the National Economic Council to create the Central Research Institute of Gas and Fluid Power.

And Zhukovsky, who also became the first director of the institute, it was his efforts that made aerodynamics an independent discipline, you know, complex fluid dynamics, it is quite difficult to describe mathematically, and Zhukovsky not only used mathematical methods, but also experimentally, solved a series of mechanical problems related to flight. He single-handedly created such basic disciplines as experimental and theoretical aerodynamics, which pushed the development of aeronautics to new heights.

The Central Fluid Institute is located in the city of Zhukovsky, 50 kilometers away from Moscow.

"I think we might as well put our hotel in Zhukovsky, so that we can run around every day." In the car, Qin Feng couldn't help but say.

If you want to visit the Soviet aviation and aerospace base, of course, it is in Zhukovsky, this is the Soviet aerospace city, and now, after Qin Feng finished speaking, he was echoed by General Lin: "That's natural, if we can stay here, it is the best, it is estimated that our friends are not at ease." ”

After speaking, he looked at Shaposhnikov, who was accompanying him, and the other party's face was obviously embarrassed, yes, in Zhukovsky City, there are many advanced technologies of the Soviets, and it will be very inconvenient to keep them there, in fact, this time I went to the Central Fluid Academy, and it was not completely unreserved.

As he spoke, the car had already driven into the Central Fluid Institute, which is the world's largest aviation research institution, but its appearance is not ostentatious, just like other buildings in Moscow, its main body, is a 5-story dark yellow building, not tall, but very wide, with narrow windows, which is also the most common architectural style of the previous era.

When I walked in, I saw the director of the Central Fluid Academy, Sakisov, this old comrade was a little fat, and the flesh on his face kept shaking when he spoke.

"Welcome our Chinese guests, this is also the first time that our Central Fluid Institute has welcomed Chinese guests." The other party said.

This sentence is not wrong, even in the past, when relations with the Soviet Union were good, everyone often went to the Mikoyan Design Bureau, and when they went there, they directly received the process and learned how to build aircraft, but the Soviet teachers obviously did not teach themselves how to design aircraft, and the Central Institute of Fluidics was the technical reserve before designing the aircraft, and it was necessary to study which advanced technologies could be used in aeronautics, and to study to have practical value.

"It's a pleasure to come to the Central Institute of Fluidics, your research results have shocked us, and the control of vortex lift by the MiG-29 fighter has simply reached an extreme." General Lin said.

Now the most popular technology is the vortex lift, the large side strip wing, is used to pull the vortex, the MiG-29 angle of attack is so large, and the vortex is inseparable, and whether it is the MiG-29, or the Su-27, their shape, in fact, come from the Central Fluid Institute.

"Yes, we are also very satisfied, the MiG-29 fighter, it is a good fighter, our most advanced fighter." Sakisov said.

As they spoke, they walked forward and entered the exhibition room of the Central Fluid Academy.

"In fact, although the MiG-29 has a good appearance, its control system is not good, it does not use active control technology, so its handling still limits the play of maneuverability."

If it was in the Mikoyan Design Bureau, then Qin Feng would never dare to say these words, after all, it would be a slap in the face, but here, when the MiG-29 was mentioned, the other party began to blow the conch again, Qin Feng couldn't help but say something, and he still said it in Chinese.

However, just after he finished speaking, he saw this dean turn his head to look at him, like that, it was clear that he could understand his words, who would have thought that this chief teacher of the Central Fluid Academy would actually be a generalist in Chinese?

"So, what do you mean by active control technology?" Sakisov asked.

Speaking of active control, that is ACT technology, this technology in China, has also carried out extensive research, J-8 wants to use this technology to improve the control performance, but because of the defects in the control software, it eventually led to a crash, which had a great impact on the project.

Now, hearing Qin Feng's words aroused the other party's interest, and the other party obviously came to test Qin Feng, everyone sweated for Qin Feng, aren't you a class with an axe? He is the director of the Central Fluid Academy, and he has been studying this thing all his life.

Qin Feng is not stage frightened, didn't you say that the MiG-29 is good? In fact, the control system of the MiG-29 is outdated, and as a third-generation aircraft, it actually uses hydraulic control! Even if it is the Su-27, it was only because of the crash that the telex was used, and it was an analog telex, not the best digital telex, good is good, a defect is a defect, Qin Feng will not have stage fright.

"Relaxation of static stability, maneuvering load control, direct force control, gust mitigation and active vibration suppression." Qin Feng said: "The use of this technology, can greatly improve the maneuverability of the fighter, of course, these are in the fly-by-wire flight control can be realized, in the hydraulic system, there can be no static unstable aircraft, MiG-29 using simple hydraulic control, but also to achieve such a sensitive control, it can be seen how advanced the shape design provided by you." ”

Qin Feng went around in a circle, and still mentioned that the level of the Central Fluid Institute was high, if it wasn't for you providing a good appearance, it would be impossible to achieve such a high level of mobility, or your technology is high.

When Qin Feng said this, General Lin nodded slightly, neither humble nor arrogant, and finally fell on praising them, which was too rare for a straight-line soldier like Qin Feng.

In fact, Qin Feng is on the basis of facts, good is good.

"Well, interesting, then, you say, in which direction should the next generation of aerodynamic technology develop?"
