What kind of magic technology is it, or is it a technology that can only be developed after clicking on a technology tree such as a supercomputer, and the threshold for the development of this technology can be regarded as much as compared to DSI inlet technology, so what kind of magic effects does this technology have?

There are a lot of magical effects, but these effects add up to a sentence: this thing can greatly increase the single-stage pressurization ratio of the compressor and fan of the axial engine, and the first-stage size blade compressor can achieve the effect that the traditional axial compressor can achieve only two stages.

How amazing is this, it can have such excellent performance, and the first-stage compressor can be used as a two-stage compressor, which sounds quite mysterious.

Well, if nothing else, let's talk about the practical application of this technology. The last face of the republic, probably just at the beginning of 2002, the old turboshaft 6 engine was improved and upgraded in China, and there were not many new technologies used, but the most important of them was the large and small blade technology studied by Professor Chen of Beihang University in front of Yang Hui.

After using the large and small blade technology, the old turboshaft 6 engine has undergone earth-shaking changes, after using the large and small blade technology to improve the compressor of the turboshaft 6 engine, the first stage can be used against the previous two-stage compressor, which is first of all to greatly shorten the number of stages of the compressor, and the length of the engine is controlled.

While effectively reducing the length of the compressor by 40 percent, this technology also increases engine power by 15 percent and reduces fuel consumption by 4 percent, making it an extremely effective and useful technology no matter how you look at it.

Now, as long as this technology is overcome, what kind of improvement can it bring to this plane?

Not to mention the turboshaft 6, just talk about the current MZ-2200 engine, the core of this engine adopts the design of a seven-stage traditional compressor, but if it is replaced with a high-pressure compressor with four-stage or five-stage blades, it brings a pressurization efficiency comparable to that of a ten-stage traditional compressor.

Of course, such a design will lead to an increase in the flow of the core aircraft, and it will truly reach the level of the core aircraft used in a heavy helicopter.

But so what, the idea is that the engine can have a more powerful power output when it has been confirmed that the overall length of the engine is 1.5 meters. When the time comes, not to mention 3000 horsepower, 3500 horsepower is still the basic value, and after striving for it, it is not impossible to reach 4000 horsepower after the follow-up change.

The size of the blade technology has its magic, but then again, the use of this technology is directly to change the compressor of the core machine, so it should be a big improvement to the core machine, even if it is said to be a newly developed core machine, there seems to be nothing wrong with it.

But as long as there is some material people know, the previous face is also the use of large and small blade technology to improve the engine, the core of the turboshaft 6 engine has also undergone surgery, but people can still happily say that I am an engine improved by the older generation of engines, numbered turboshaft 6C.

Although the two engines themselves are already worlds apart, the gap between the old and new engines is as big as the F-18A and F-18E of the US imperialists, so this is nothing more than selling dog meat on the head of a sheep, but this is still a great inheritance of some predecessors' technology.

However, AVIC Southwest is not afraid of this, and when the time comes, it will give the new engine a new number: MZ-3500 is actually not inappropriate, and it will depend on the situation at that time.

With such a new engine, coupled with the Z-8 helicopter as the foundation, you say that it is a magic change, a new development, anyway, to really prepare to develop a heavy helicopter that reaches the CH-53E level, at least in terms of power system can be regarded as very simple.

The size of the blade technology is so excellent, so now at this time of course to prepare for research and development work, the last professor Chen is also doing this technology, it seems that it also started in the early 90s, the difference is that the last professor Chen did this technology, some are just ordinary support at the national level, so it was only in 2002 that it can be regarded as a real installation and practicality, and at that time, the Republic can only be regarded as the fourth country to break through this technology.

Well, this time Yang Hui's arrival is to give Professor Chen strong support, funds: give, resources: give, even if it is a supercomputer, although in the 90s there was not much in China in this regard, but after coordination, it can still meet him.

In any case, it is necessary to develop this technology in the early 90s, but it must not be able to break through in the new century like the previous one, and when the fourth country to break through this technology, you must know that this plane also began to develop in the early 90s!

"If you want to talk about the technology of large and small blades! I have indeed heard of it, and I remember that there seemed to be some rumors in the United States before, as if the United States was also starting to study this technology, could it be that General Manager Yang also planned to wade into this troubled water? ”

I didn't expect Professor Chen to speak with such humor, and at this time he can still use words like wading through troubled waters, it seems that he is indeed a wonderful person!

"Where, we can't say that, my side is simply optimistic about the size of the blade technology, that this technology is conducive to making us in the field of gas turbomachinery and the West advanced countries zero gap, and this hope is very likely to be realized. Everyone knows how vicious the vision of the United States is, and they all attach so much importance to this technology, and we must follow up. ”

It can be seen that Professor Chen is still a little moved at this time, after all, he himself did have some ideas about this technology before, and now there happens to be a financier who is willing to invest in this project, so it is really a match made in heaven.

However, when talking about the project, it is definitely impossible to just say that I am optimistic about the project, and the most important thing is to talk about the money: "Mr. Yang, to tell the truth, I really want to take over this project, but it is still the same sentence, what are you willing to give support, if it is just a small fight with the idea of unintentionally inserting willows, then I am really here"

The meaning that was not said behind these words must be understood by everyone, and Yang Hui knows what to say at this time, if nothing else, there is only one sentence.

I believe that Professor Chen, as an important figure in the field of gas impellers, also knows what the words "high push pre-research" mean to AVIC Southwest, so I don't think I need to say anything more about the importance of this project. ”

High-push pre-research, this project was only a project of the 624 Institute before, and it was not very famous before 86 years, after all, the project at that time did not produce results, and no one can say what the results of this high-push pre-research American imported products will bear in the end after they arrive in the Republic.

But after 90 years, all people in the industry are enthusiastic about this high-push pre-research project, this guy's mid-push core machine, which is derived from CG-2000 ultra-large bypass ratio turbofan engine, turbofan 12 military mid-thrust, and QC-160 gas turbine, so many good things are all descendants of the mid-push core machine, and the mid-push core machine is from the high-push pre-research project.

Now that the 2 high-push pre-research projects have been quietly established in AVIC Southwest Corporation again, it naturally means that there is more investment than the previous high-push pre-research projects, and to be able to be selected for such a high-level special technology, will it be an unintentional move?
