The MiG-29 in the sky roared by, making a variety of difficult maneuvers, all thanks to the perverted thrust-to-weight ratio of the MiG-29, two RD33 engines provide 16.5 tons of thrust, providing the MiG-29 with a thrust-to-weight ratio of almost 1.

Naturally, the various maneuvers of the MiG-29 are quite fancy, not only the other members of the accompanying delegation to the Republic were drunk, but even Yang Hui was a little drunk, although the previous Yang Hui had also seen various maneuvers, and the various stall maneuvers made by the F22 were also seen.

But now the MiG-29 flying by Soviet pilots does have a different beauty, and the Soviet pilots driving the MiG-29 are like a drunk driving an off-road vehicle, doing all kinds of thrilling things.

The American F22 has done a stall maneuver performance, Yang Hui feels that it is more like a supercar driven by a professional driver, although it also gives people an adrenaline rush, but it can never give the Soviet pilots the feeling of air performance.

When the MiG-29 landed, a few people were reluctant to leave, originally Yang Hui was going to go to see the MiG Design Bureau's fast reaction center to study, and after returning to the Southwest Science and Industry to build the Southwest Science and Industry of its own fast reaction center, there is also a reference.

However, after the MiG Design Bureau was seen by Yang Hui in the yellow MiG-29 during the test flight just now, he said that he would not let Yang Hui and his party go to see the fast reaction center, and in the end they could only leave with regret.

After the Soviet Foreign Ministry gritted its teeth at the MiG Design Bureau, everyone chose to have lunch, and then went to the Central Engine Research Institute, which Yang Hui wanted to go to the most, which was what Yang Hui cared about.

Yang Hui actually didn't pay much attention to the development of the aircraft. Yang Hui is most concerned about the development of aero engines, which is the weakness of the Republic's aviation manufacturing industry. It is also what Yang Hui is most concerned about, at least the experience of the Soviet republics is easier to accept and digest.

When walking to Moscow Aero-Engine Street. Yang Hui felt that the Soviet Union attached great importance to the aviation industry, and set aside a large area of land in the capital city for aero-engine research, and named it Aero-Engine Street, which is probably still a little difficult to do in the capital of the republic.

Walking into the headquarters of the research institute, I could already hear the neighing of the engine, the sound was not Mrs., it didn't feel like a large and medium-sized thrust aero engine.

Perhaps sensing Yang Hui's curiosity, the enthusiastic vice president of the Academia Sinica, Xi Luojing, took Yang Hui directly to the source of the sound: the high-altitude test bench.

When he saw the high-altitude test bench here, Yang Hui was not calm. This hairy man is also too ferocious, and he directly built the electricity, water, and oxygen consumption monster: high-altitude test bench to the capital city, which is really

This is the low-thrust aero-engine high-altitude test we are doing, the energy consumption of the low-thrust engine high-altitude test is not as good as the high-thrust engine high-altitude test, we did not continue to leave it in the research institute headquarters, you can visit it together.

As he spoke, he really beckoned Yang Hui and the others to go over to the side of the high-altitude platform, because the high-altitude platform test cabin was being tested, they could only watch the high-altitude platform run at high speed on the side, but the data measurement and control part on the side let Yang Hui see the approximately. I might be able to mention 624 when I go back.

There was nothing to visit in the follow-up small high-altitude platform, and what excited Yang Hui the most was their engine fast reaction center, which Vice President Xi Luojing allowed Yang Hui and his party to visit.

In the aviation industry, not only the aircraft research institute has a fast reaction center, but also the development of aero engines is inseparable from the fast reaction center. As a purely mechanical device, the engine relies more on rapid manufacturing and testing in the development process.

The Central Aero-Engine Research Institute of the USSR, in addition to the headquarters of the institute located in the city of Moscow, is located on the outskirts of Moscow, forty kilometers away. There is also a trial production center that undertakes large-scale scientific research tasks.

The fast-reaction center, a key component of the engine, is 40 kilometers away. Yang Hui and a group of visitors sat in one or two cars in front. Vice President Hirotin in the back has his own car.

"Comrade Vice President Hirotin, take these people to visit the most important engine trial production center, as well as the high-altitude platform that I just visited. Is it that they are watching too much? Diplomacy between our two countries is not very good at the moment, and it may involve leaks. ”

At this time, Soviet diplomats were even more worried than Vice President Hirotin, after all, the development of an aero engine was more difficult than the development of an airplane, and it seemed to laymen that it was all the more necessary to keep it secret.

But Vice President Xi Luojing is not worried about these at all, for the difficulty of the development of an aero engine, insiders know clearly, in Xi Luotin's view, even if it is to take the apprentice to complete the whole process of developing an aero engine.

It is also difficult for apprentices to design an engine on their own, and the development of aero engines has too high requirements for comprehensive national strength and technological accumulation, and Hirotin is not optimistic about the republic, an apprentice of several decades ago.

"This is just wrong, there is nothing to keep secret about the development process of aero engines, and it is useless to read many things. Each engine is developed according to the specific industrial manufacturing base of the country, the industrial base of different countries is different, there are good and bad in all aspects, and the trade-offs of design are different. ”

Vice President Xi Luojing explained indifferently, in fact, from the bottom of his heart, Xi Luojing really hopes that this visit can see something and learn some technology, after all, after many years of teacher-student relationship.

Herotin also went to the Republic decades ago to support the construction of the Republic's aviation industry, when Herotin was still quite young, just in his early thirties, and he was just an engineer who was sent to take charge of the technology, responsible for teaching the Republic how to produce turbojet 5 engines.

Originally, Shirotin was just an engineer, but the students of the republic regarded Shirotin as a professor and an expert, and brought some scientific research problems, which made Shirotin very helpless, and it was not his job in the first place.

Hirotin is a responsible teacher, although he does not know much about scientific research, but in order to be able to answer students' questions, active research is not a special scientific research problem, and since then he has begun the road of transformation, from engineering and technical personnel to scientific researchers.

Xi Luojing vaguely remembered several of his friends in the Republic at that time: two aero-engine practitioners surnamed Wu, both of whom were leading figures in the Republic of Aero Engines, especially Wu Zhonghua, who was not only a friend of Xi Luotin, but also a teacher, and took Xi Luojing into the door of aero-engine scientific research.

Now that I think about it, without those days, Xi Luojing would not have today's vice president, and the reason why he was willing to let Yang Hui and his party visit just now was still a feeling. On the one hand, it is a deep understanding of the difficulty of the development process of aero engines, so that Hirotin is willing to let the visiting group see it, and it will not leak secrets anyway; On the other hand, there is the special affection of Herotin's heart for the republic.

This time, he heard that there were signs of diplomatic relaxation between the two countries, and he was very happy, and he hoped that through his own efforts, the two countries would return to the relationship between brothers and comrades in the past, so there was no problem for Yang Hui to visit the Central Aero Engine Research Institute.

When the car stops in a place called Turayev Village, even at the trial production center of the Central Aero Engine Research Institute, there are tall factories, pipelines, and a huge reservoir on the side.

A variety of all-encompassing supporting measures let everyone know what an aero engine research and development center is, and know that the research of aero engines is something that can only be played by a big country.

Of course, in Yang Hui's view, a big country like the Republic should have its own aero engine industry, which is the sign of a great power. (To be continued......)
