"What does Liu Suo mean, do you want the overhaul line in Ukraine?"

Hu Wenhai touched his chin, showing a thoughtful look.

606 wants to give up the competition with the Turbo Research Institute in the Taihang engine project, which is actually meaningless to Hu Wenhai said. Our President Hu is not the general manager of AVIC, nor is he the director of the Commission of Science, Technology and Industry for National Defense, nor is he the chief of the general assembly. The Taihang engine undertaken by 606 is a one-engine with three types, and it can be said that it is a project of Tianzi No. 1 in the military system.

Now that Liu can take this matter out, it is obvious that there should have been a conclusion in the system.

Compared with the progress of the Taihang engine in history, the prototype has been put on the test bench as early as 90 years when there is no shortage of resources in the military industrial system. By last year, before the collapse of the Soviet Union, in order to cobble together funds, a batch of Su-27,606 that was supposed to be allocated to the Soviet Air Force was delivered to China in a surprise manner, so that a test flight platform was also obtained.

The twin-engine Su-27 can replace one engine with a prototype of the Taihang engine, which directly advances the project schedule of the Taihang engine by a large margin. But it is precisely for this reason that the Taihang engine after installation can be regarded as exposing its "not very good" system.

Other engines are jet engines, and Taihang engines are jet engines, which makes the face of the 606 Institute not very good-looking.

On the other hand, the changes in the world situation caused by the collapse of the Soviet Union have finally affected China's aero-engine industry.

The complete and destructive relocation of the Salyut plant by the CPSU during the retreat from Moscow led to rather serious problems with the supply of AL-31F engines. Although Rurika also has the production capacity of the third uncle, the production capacity is bound to be in short supply.

As the main customer of the current third uncle, the engines equipped with the Su-27 fighters imported by the Chinese side are already very tight. It is conceivable that such a supply capacity will form a serious supply crisis for the domestic fighters that may temporarily use AL-31F as power in the future, including the three projects of No. 10, No. 11 and Panda.

It is obviously not in China's strategic security interests to pin all hopes on the CPSU to rebuild the salute in Komsomolsk, or to expand production capacity in Rurika.

Since the Chinese side has decided to localize the Su-27, it is actually a matter of course to synchronize the localization of the AL-31F.

The 606 Institute has another advantage in turning to the localization of the third aunt, that is, it can digest the technical strength of the Soviet side brought by the double-introduction project nearby. With the support of the original engine experts of the Salyut Factory provided by the CPSU, the Singer Factory is absolutely confident that it can overcome the localization project of AL-31F.

In that case, it would not be an unacceptable outcome to withdraw from the competition with the turbine institute.

For AVIC, it is certainly not as efficient and energetic to carry out two overlapping engine projects at the same time as to fully support one project.

The problem, however, ......

Hu Wenhai touched his chin and took two steps hesitantly, not knowing if this could really be regarded as a good thing.

Of course, the Taihang engine is not very good in the early stage, and the spraying of parts is not all a joke. But just like young people, no matter how much they understand, they still want to take shortcuts, and if they haven't really experienced failure, they won't understand that failure is also wealth.

Even if it is a universal engine, the 9 core is a product developed in the sixties, and it is equipped with engines from the F101 to the F110 and the CMF56. The F101 was reduced and the GE15 core machine was developed, and the GE15 developed the YJ101 vortex, and the YJ101 plus the outer duct became the F404, and the F404 and F101 were crossed to obtain the F110......

In this way, there are hundreds of improvements, derivatives and iterations developed from GE9, and the performance was not satisfactory in the early days, and various indicators were also improved while using feedback.

If the GE9 was also sprayed with parts and dismounted when it was tested that year, would there be no follow-up models of GM in the future?

If it were the background of the original history, the military industrial system could only concentrate on doing big things, Hu Wenhai would also think that the turbofan 10 had indeed taken a lot of detours, and it was always good to save a little resources for the right route.

However, what is the reason why Mr. Hu has been tossed from the sea to the sky in the past ten years? Isn't it just crazy to give the military industrial system a "sho_me_the_money" golden finger?

Today's military industrial system is wider than the nineties in history!

Although the idea of Taihang engine is wrong, no one knows whether its trial and error has a key impact on the later development of China's aviation development - at least, Hu Wenhai, as a hobbyist, does not dare to assert what the relationship between the turbofan 10 and the turbofan 10A is.

Even, the experience gained from the Taihang project is not something he can know about the significance of Jiang Hefu's turbofan 15 later. And once the GE9 core engine development Taihang route is launched, then there will be another serious consequence - this means that China's aero engine completely parted ways with the United States and became a market dominated by the Soviet system.

Hu Wenhai doesn't know which of these two routes is better or worse, so neither of these two routes can be abandoned. Whoever walks on only one leg is lame. No matter what time it is, you can walk steadily on two legs.

Thinking of this, he suddenly stopped, raised his head, and said to Director Liu in a deep voice: "Ukraine's AL-31F overhaul line, this is not a problem. It's just money, and you can always come up with a price that satisfies Madasic. But...... 606 has not considered that once the Taihang project is lost, how will the Shengjing Aviation System deal with itself in the future?"

China's aviation system is a monopoly industry, and monopoly is naturally followed by excess profits. But in China's case, this excess profit is not without a price, and the price is that the aviation system must contribute to national defense.

606 is the supporting research institute of Shengjing Aviation System Aviation Development, if all branches are cut to concentrate on the localization of AL-31F, this project will definitely be able to be taken down. But then what? The entire Shengjing aviation system will lie on the Su-27 platform and eat to death in the future?

Once the Su-27 platform loses its military value, why does Shengfei still enjoy the excess profits of the aviation industry?

With Sheng Fei's "past" performance, Hu Wenhai feels that there is no such possibility......

"I have a suggestion that I hope Liu will consider it. ”

Director Liu frowned at the same time, this is indeed a big problem. Make every effort to promote the localization of AL-31F, that is to say, the 606 Institute will basically give up its self-research and development capabilities. Don't look at the slow development of self-development, but it is easy to give up.

Even if an aviation engine is put into the market, it is understated to track R&D and improvement for one or two decades. In the past ten years, I have been on the platform of AL-31F, pondering other people's technical routes and product ideas, and basically I can't get rid of the influence of the Soviet style.

However, the problem is, after all, the AL-31F is a product that has evolved from generation to generation of the Rurika Design Bureau. Without this process from TP1 to AL21 to AL31, how dare you say that you can understand Rurika's thinking, how dare you say that there will be no problems in the design of the next generation of engines?

Director Liu nodded heavily, and said with a straight face: "Mr. Hu's suggestion, we must consider it carefully." ”

Hu Wenhai's name is outside, just as the so-called shadow of the famous tree of people, he said politely, but Director Liu did not dare to be sloppy.

"The GE9 core engine of the turbofan 10 is obtained from the CFM56 engine, even if the 606 decides to withdraw from the competition of Taihang, have you considered it...... Based on the current turbofan 10, how about developing a military-grade turbofan engine with a large bypass ratio?"

"It can be used not only for future domestic trunk airliners, but also for military large transport aircraft. ”

Hu Wenhai waved his hand and motioned to Director Liu to let him finish his words for the time being: "Don't always think about cobbling together on the basis of GE9, it turns out that aero engines are not building blocks, and the systems developed by the United States and the Soviet Union on different core aircraft have not considered modularity at all." There is only one way for us to master the design of a core machine, and that is to honestly burn enough fuel on a core machine. ”

"After thoroughly understanding the core machine of GE9, we can design a large ducted turbofan engine of the CFM56 level before it can be used in our domestic large aircraft. That is, if you have eaten GE9 thoroughly, whether it is the localization of AL-31F or the competition to participate in the next generation of aviation development, Shengfei may be invincible. ”

If Sheng Fei has this determination, he will not be willing to stop at the glory achieved in the past. Not to mention an AL-31F overhaul line, sooner or later, Madasic will pack it up and move it back to China. At that time, the only ones who can receive this asset are 606 and Dawn Factory. ”

As soon as Hu Wenhai's words were finished, he could clearly feel that Director Liu's breathing suddenly became heavy!

That's Madasic! It's the D-18T's Madasic! It's the Madasic that can send the An-225 to the sky!

In the past, China did not attach importance to the development of transport aircraft, but with the change of thinking about army building, this status quo will inevitably change. However, looking at China, there are no similar products similar to CFM56 large duct than turbofan!

There is no need to compete with the 624 Institute, you can use the accumulation of the turbofan 10 project, which is an irresistible temptation for the 606 Institute.

It is conceivable that if the technical strength of the motor is obtained after the GE9 is mastered, no company in China will be able to threaten the dominance of the 606 Institute and the Liming Plant in the field of large-bypass ratio turbofan engines.

Even back to the most glorious era of Sheng Fei, the 606 Institute has never achieved such a status.

"I think, 606 ...... Think about it. Mr. Hu's suggestion is really attractive, but the stakes are very high, I think it is better to be cautious and listen to the opinions of all parties. ”

"Of course, that's as it should be. Hu Wenhai nodded as usual, but couldn't help but sigh in his heart.

It's a pity that if the 624 people had made the decision, they would have been opening champagne by now.
