readx; If you want to say that a special trip from the southwest headquarters of AVIC to the 624 Institute to bid for the four-generation turbofan project, then according to the reason, in terms of the importance of the four-generation push-out project, it must be necessary, but this time it is definitely wrong to say that Yang Hui is a special trip to the four-generation push, after all, when he came from Chang'an this time, this guy also said that he would prepare to start the wide-body passenger aircraft. Pen ~ fun ~ pavilion www.biquge.info

This time, it happened that the current chief engineer of the 624 Institute here guessed that there might be a big project, so Yang Hui satisfied his curiosity: "This is really right, indeed I am not only for the fourth-generation turbofan engine project, nor for the turbofan 12C thing, the main purpose of this time is to come for the new civilian super-thrust large-bypass ratio turbofan engine project, that is, the object of the super-large flow high-altitude platform under construction in your institute this time." ”

This is straightforward enough, even if a person who doesn't know any news in advance, after hearing this, he also knows what the engine project Yang Hui wants to bring is, not to mention Jiang Hefu, a great god who can sit in the position of the chief engineer of the research institute.

If you want to say what is the biggest ideal of Chief Engineer Jiang in this life, in fact, according to him, it is "two advanced", namely: presiding over the research and development of an advanced main military small bypass ratio turbofan engine core machine; He presided over the research and development of a top-level civilian ultra-large thrust turbofan engine core engine.

As long as the above two projects can be completed, in Jiang Hefu's own opinion, this life will be considered complete, and now he is close to completing the first stage of the goal in this life, to say that the core engine project of the fourth generation of military large-scale push turbofan is definitely a world-class military aviation engine, as long as the development of this core aircraft can be completed, the first advanced will be satisfied.

As for the second advanced, originally according to the idea was to follow the path of the previous pusher core machine, and when the time comes, after the improvement of the fourth-generation pusher core machine, the focus on military use of this core machine will be changed to focus on civilian indicators, and finally it will be guaranteed that it will be able to come up with a super-large bypass ratio turbofan engine that can meet the requirements of the future C-17 level military strategic transport aircraft in terms of performance, or it will be provided to the Il-96 class passenger aircraft that may appear in the future for the Republic to use.

The previous idea was to continue until 94, and it was only then that I learned that the reason why the newly built high-altitude platform project was high and scary was because the company was going to develop a civil turbofan engine with super high thrust, and the index was aimed at the world's most advanced civil aviation engine, so the second advanced must have landed.

There are even some who are not quite convinced: "Is it really going to launch a civilian turbofan engine with super thrust?" This is finally the opportunity, but according to the current situation, coupled with the comprehensive consideration of various factors, it should be understandable for the company to launch such a large project, and the time is probably just right. ”

The time is just right, and there are many reasons involved, although Yang Hui came to announce the launch of the project this time, which is about 1 year overlap with the estimated finalization time of the fourth-generation turbofan core machine, but the time of this overlap mainly depends on what it does.

For example, at this time, the fourth-generation big push core machine needs to do the test work of the follow-up core machine, and even if the development of the civilian ultra-large thrust turbofan core machine is immediately launched, the whole machine test of the core machine will not be carried out at least two or three years, and all that is needed during this period of time is the relevant engineering designers to do the design work of the core machine.

It is even possible that the design work is not even counted, this may just be a choice of various technical architectures, and determine the general design direction, when the time comes to consider the design of the core machine according to the mature technology that is now available in China and a new technology that is about to break through, and coordinate all parties to conduct in-depth and targeted research on the relevant technical departments.

Therefore, it may be that in the next year, the entire 624 Institute will usher in the simultaneous development of two blockbuster core machines, but these are not a matter for the 624 Institute, as long as the relevant development funds can be put in place on time, and the accumulation of basic technology can meet the requirements, what is needed in the future is just to wait for time.

So also for Yang Hui, as long as the finalization of the civilian super-thrust core aircraft can be guaranteed around 2000, everything else is not a problem: "That's right, this time I brought the civilian super-thrust turbofan engine project, this is a big gamble in the next ten or even twenty years of our United Aero Engine Company, relative to the importance of our United Aero Engine Company, it is another RB-211 engine, as long as we can finally make this project, United Aero Engine will become the fourth largest international aviation engine. ”

It is the dream of all engineers and technicians of the United Aero Engine Company to make the United Aero Engine Company a existence comparable to the three giants of Hangfa, and they are also making unremitting efforts and struggles for this dream.

"Become comparable to the existence of the Big Three, that is, we can talk and laugh together with these three on an equal footing, and when the time comes, they will continue to fight the landlord for decades, because of our arrival, so as to become a four-person mahjong! It's just that it's not clear that after they get used to playing landlords, can they adapt to a high-IQ "game" like mahjong? ”

This metaphor is extremely appropriate, and Yang Hui on the side was dumbfounded after listening to it, this Jiangda chief engineer has only been in Fucheng for less than ten years, looking at this situation, I haven't learned anything else, but I have learned the essence of this entertainment method here in Bashu, you must know that this is a four-person mahjong, I really don't know if the three giants will be able to adapt to it at that time? At this time, Yang Hui also smiled silently in his heart.

"The blueprint for the future is very beautiful, but you don't know our current situation, we haven't even figured out the technical design framework of the core machine yet, let alone the rest of the future, since you said that you have thought about this aspect before, then why don't you first talk about what structure you envision the core machine will use, and what advanced technologies to use?"

For the civilian super-thrust turbofan engine, the development of the core engine will be different from the number of roads taken by the previous 624 core engine development, and it may be that the previous 624 institute, no matter which core engine is developed, is to take the general core engine route of military and civilian, large bypass ratio/small bypass ratio turbofan, turbojet, turbo pulp, and turboshaft engine, so there is a full bloom of the aero engine of AVIC Southwest.

However, after the development of the core engine used by the civil high-thrust turbofan, in fact, it has only one engine type in its life: super-large bypass than turbofan, as for other small bypass than turbofan, turbojet, turboshaft or something, there is no need to think about it, these are impossible luxuries, so when designing such a core machine, it has its own special features.
