Hu Wenhai's generous statement can be said to be happy for a while. Pen & Fun & Pavilion www.biquge.info

However, for Liu Daxiang and Jiang Hefu, this visit was just the beginning.

The R-35 data was certainly a relief to Project Ten, but the bigger problem was still in front of them.

Even if the Turbojet-15 was able to enter service smoothly and was replaced with an imitation of the R-35, the Turbojet itself was already behind the times. As a designated domestic third-generation aircraft, the J-10 will never be willing to use turbojet engines as power forever. The turbofan's Taihang engine is its best match.

However, if you really have an iron heart, you have to be too good not to marry, I'm afraid that the young man will have to boil his head white.

How could Taihang, a lady who was afraid of life, come down the stairs early, was the real intention of the two of them to visit Hu Wenhai this time.

Speaking of which, it is still necessary to blame Hu Wenhai for the matter.

From the F-14 to the Su-27's entry into China, it can be regarded as completely feeding the appetite of the Air Force. In order to make room for the future mass-produced Panda fighter, the Air Force stopped the improvement of the J-8, abandoned the Thunder that had entered the end, and even the Super 7 project was affected. For the MiG-23, which was abused in Annan as a target shooter, the Air Force even has a psychological shadow on its trust in the second-generation aircraft after realizing the gap between the second and third generations.

No matter how many second-generation aircraft are in front of third-generation aircraft, it seems that they are not enough to form an advantage. In this case, what other second-generation aircraft should be developed? It is the right choice to devote limited resources to the development of third-generation aircraft.

With such an idea, the development of turbojet engines has naturally been ignored, who made turbofan engines the standard configuration of third-generation aircraft?

Jiang Hefu, who was originally engaged in the improvement of the turbojet 13B, after the 624 Institute was taken off the shelves, according to the practice of domestic engines following the aircraft, there was naturally no need to continue to do it.

So under this mistake, Jiang Hefu started the pre-research work of advanced and medium-push two years in advance.

Now that the second-generation aircraft has been fully discontinued, the aviation of the third-generation aircraft is the hairy cargo of the AL-31F in addition to the old TF41. The only turbofan project in China is the only seedling of Taihang.

After two years of pre-research on advanced turbofan pushing, the push-out project is facing an unsustainable situation.

To put it simply, at present, all the resources of China's aero engine industry are concentrating on the Taihang project.

Taihang's one shot with two types is not a joke, it can almost be said that it is a gamble on the fortune of China's aero engine.

As a result, China ranks among the third-generation engine producers. If you lose, everyone knows what the result will be......

In this context, the research and development of Taihang engines must be successful.

Jiang Hefu's talent and ability in the research and development process of the core machine were tapped out by the superiors.

Participating in the research and development of Taihang engine as an option was placed in front of Jiang Hefu. There was no need to think about it at all, he took over the burden decisively. At the very beginning of his tenure, Jiang Hefu put forward a proposal that attracted much attention.

The report on the development of derivative development models of a series of core aircraft went straight to the sky and caused a violent earthquake up and down the aviation development system.

A Taihang supporting the No. 10 project has already made the 606 Institute anxious, and Jiang Hefu actually wanted to create more trouble for the project?

To briefly explain this report, the core idea is that the core machine of Taihang cannot be equipped with only one Taihang, but should derive more development models according to the core machine of Taihang. Not only can it be installed on the J-10, but also by adjusting the design of the outer duct, it must be installed on other fighters, and even its large bypass ratio afterburner modification can be installed on the bomber, and the non-afterburner type can be used in transport aircraft, or develop passenger aircraft engines with its core engine, and then derive advanced industrial power gas turbines.

Ideas are naturally good ideas, but they are too painful to execute. If you really want to do this, the first point is to require the designer to thoroughly understand the core machine and high voltage, external duct, and even the entire system of Taihang.

This is really a huge project for the core machine of Taihang's F101. If the country can really eat the F101 thoroughly, it will not be a fatal accident in the future.

Taihang's original idea was originally the core engine of the F101 plus the outer duct of the AL-31F, which was an approach that did not understand the design of the turbofan. It was only after the failure of WS-10 that Zhang Enhe realized that this approach would not work.

But that was already the end of the nineties and the beginning of the twenty-first century, and Jiang Hefu was ordered to undertake the research and development of the WS-10A in the situation of the possible failure of Taihang.

But in fact, compared to the WS-10, the WS-10A can almost be said to have redesigned a turbofan engine.

That is, from the beginning of the research and development of WS-10A, Jiang Hefu promoted the reform of China's aero engine research and development model. For the first time, the development of turbofan engines was carried out in accordance with the scientific development model of "basic research, key technological breakthroughs, advanced components, core engines, verification machines and model development".

This can be said to be a milestone in the research and development of China's aero engine!

Jiang Hefu learned the lesson of the poor progress of the Taihang engine, and thoroughly understood the design of the core engine of the F101 and AL-31F from scratch. Facing the design of the WS-10A with the attitude of knowing what it is and knowing why it is true, this is the result of the later WS-10A installation of the J-11.

However, by that time it was already too late, and the entry into service of the WS-10A and WS-10B did not allow China to catch up with the first echelon of the United States and Russia. The production capacity of both engines has also not been able to scale up to meet demand, which is why the WS-10A started too late.

Looking back on this period of history, Jiang Hefu is the man who is in the focus of the world.

And a man who pulls the wind, no matter how history changes, will always become the focus of the world.

This meeting with Hu Wenhai was an important move for him and Liu Daxiang to promote the plan of deriving and developing models of the core aircraft of the series.

"Mr. Song's problem has been solved, but the task of Dean Liu and Chief Jiang has not been completed!"

As an intermediary, Tu Jida can be said to be a basic skill in threading the needle. Seeing that Song Wencong's matter was over, he naturally wouldn't forget that there were Liu Daxiang and Jiang Hefu waiting beside him.

He glanced at the two of them, nodded lightly, and said to Hu Wenhai: "Mr. Hu is cooperating with Xifei, and many people are looking at it. To say that those of us who are engaged in aircraft design have no idea, hey-"

"That's a bit of a self-defeating one. ”

It was Jiang Hefu who answered Tu Jida's words, he pursed his lips, and said with a straight face: "Hu is always famous as it is better to meet, then we will not say secret words in front of the Ming people." ”

Hu Wenhai raised his eyebrows and smiled secretly in his heart. Who said that engineers and scientists can't play tricks, don't you see Jiang Hefu is very slippery?

Worried that Hu Wenhai would not be able to speak, he put down a big hat before talking. It's better to be famous than to meet, why are you too embarrassed?

Aircraft designers and aviation developers are all guys who must compare every gram of weight, and they can strive for perfection when calculating numbers, and it is the same as calculating people's minds.

"The Americans are much more advanced and economical than us in the research and development system of aero engines, especially the practice of deriving models of core aircraft, which I think is very worthy of domestic reference. Jiang Hefu said this, and sighed slightly: "The small number of orders for my country's air force is the result of the general environment, and it cannot be changed in a short period of time." Relying on the production of military aircraft to support follow-up product and technology research and development is more difficult for domestic military aircraft systems. However, if a series of dual-use technologies can be developed, the profits of the civilian part can be relied on to share the cost of research and development of military technologies. In this regard, the Yun-7 regional airliner cooperated by Mr. Hu and Xifei can be said to have opened up a new situation!"

"Ahem, we are also inspired by Yun Qimin. I heard that Mr. Hu and Xifei are cooperating in the project, and there will be a 100-seat regional airliner plan in the future? I don't know what kind of product is going to be used for the engine of this aircraft?

Jiang Hefu looked at Hu Wenhai a little nervously, and his palms were already full of sweat unconsciously.

For Hu Wenhai, it may be just a core component of a relatively important project, but for him and Taihang, it is a fateful moment.

Hu Wenhai hesitated, but still gave Jiang Hefu a definite answer. When it comes to the choice of new regional airliners, to be honest, he doesn't have a lot of options.

When he cooperated with Rolls-Royce to establish the Heavy Industrial Power Import and Export Company, Hu Wenhai realized Rolls-Royce's concessions in many aspects by entering or even monopolizing the Chinese aero engine market.

He frowned slightly, as if it was a little difficult to speak, but he still said frankly: "Not to mention the turboprop engine of Yunqi civilian, the next 100-seat regional airliner, Xinfei Company plans to use the RB211-535C engine of Rolls-Royce." ”

"RB211-535C is 37,400 pounds of thrust, if the wingcrane dual-engine scheme is adopted, the power demand for a 100-seat regional airliner is overflowing, which is not economical!"

is worthy of Jiang Hefu, as soon as Hu Wenhai's words came out, he had already discovered the key points. The RB211 series engines are actually developed for mainline airliners, and it is not cost-effective to barely use them in regional airliners.

"The aero engine of a civil airliner can be freely chosen according to the situation, and in fact there is no need to hang yourself on the tree of RB211-535C. ”

Jiang Hefu struck while the iron was hot, and Tu Poor Dagger said: "I suggest that Mr. Hu can consider that even if the RB211-535C engine is used in the early stage, it is completely possible to design an aero engine that is more suitable for the needs and economy of the new flight at the same time." ”

"Just like the United States has developed the CFM56 large ducted engine on the basis of the GE9, the core engine of the F101 turbofan engine. We hope to get the financial and resource support of Mr. Hu to develop China's own series of core aircraft! With the core aircraft, the large ducted engine of the new 100-seat regional airliner will be a matter of course. ”
