Although the noon Hongqi factory program is very good, but those who know some inside information understand that the program of Southwest Science and Industry is the most important, although most people do not know what the program of Southwest Science and Industry is like, but the technical data of the advanced core machine in the hands of Southwest Science and Industry is not too confidential, which at least allows some people to guess the general situation.

After the 624 Institute completed the finalization of the core machine, the review team returned to the imperial capital with the technical data on the advanced core machine, how could some well-informed insiders not know.

"Lao Liu, put your ears to the light later, the southwest science and industry plan will definitely be refreshing, compared with the plan of the Red Flag Factory this morning, it is just a firefly and a bright moon!"

Obviously, the person who spoke was a well-informed person in the imperial capital, and after listening to the plan of the Red Flag Factory at noon, he already had a rough comparison in his heart, and at this time he was showing off his prophetic vision to his companions.

And this companion on the side also played a good supporting role, with an incredible expression that everyone could see.

But he still has great expectations for the Hongqi factory plan, after all, the Hongqi factory plan is definitely authentic British blood, this is the birthplace of the modern industrial revolution, and when it comes to the attainments in the field of aero engines, it has always been in the first echelon.

"That's a bit too much, isn't it? As far as I know, the technical ability of the Hongqi plant is also quite good, the most important high-temperature turbine technology of the turbofan 10 engine that Southwest Science and Industry relied on to become famous, that was completed with the assistance of the Hongqi Factory, and the current Southwest Science and Industry has not been able to surpass the Hongqi Factory too much. It is not known who will die in this encounter. ”

This obviously also has in-depth research on the turbofan 10 engine, and even the things when Southwest Science and Industry developed the turbofan 10 engine in the early years remember it clearly. It is not said that he is not an old driver.

But it doesn't make any sense, that's all in the early days. When it comes to technical assistance, this kind of thing has not been done by either side.

"This is all in the past, the high-temperature turbine developed by Southwest Science and Industry for the turbofan 10 is definitely more than the Spey 202 engine introduced by the Hongqi Factory, and the reason why the current turbofan 9 thrust is greater than the original thrust of the British factory is because the Hongqi Factory has been helped by Southwest Science and Industry when it is localized, and it uses the high-temperature turbine technology used by Southwest Science and Industry in the turbofan 10."

You can know the secret history of the turbofan 10 engine, and people can also know about the development of the turbofan 9, this kind of mutual technical support is really normal, and the technical cooperation between the two units is also very good.

"It's like"

Just below the crowd whispered all kinds of whispers. When I guessed what good things Southwest Science and Industry would bring this time, the chief engineer of the new generation of military turbofan engines of Southwest Science and Industry also came out, and naturally I would not panic if I had dry goods in my hand.

As the person in charge of the new generation of medium thrust turbofan of Southwest Science and Industry, Chief Engineer Li has studied the new generation of medium thrust core machine developed quite thoroughly through a month of detailed technical architecture design, and it is to the point at first.

"The Southwest Science and Industry Program is not an improvement on our existing turbofan 10 engine, the old generation of turbofan 10 due to the backwardness of the core engine design, has been far from meeting the needs of a new generation of high-performance turbofan engines. To this end, we have developed a new generation of medium thrust core machine in advance before the start of the new generation of medium thrust turbofan project. ”

On the question of the new generation of mid-push core machine. Southwest Science and Industry must have made a lot of efforts, and the publicity and packaging scheme of this core machine was introduced a lot in the publicity of the CG-2000 engine, which can be described as experienced.

Although Hongqi Factory learned a little from Rolls-Royce in this publicity, it can't compare with Southwest Science and Industry, which has been mixed in the international aviation industry market for a long time. In addition to the existence of Yang Hui's cheating

Although it was not possible to make any simulation animation demonstrations in these years, and due to the hardware limitations of this venue, it was not possible to promote it by playing promotional videos.

But after a full-scale model of the core machine built by CATIA. It can still be reflected in the way of pictures, and after processing, it is a beautiful core machine side view and section.

"Shhh Is this the core machine that Southwest Science and Industry has always regarded as a heart and liver baby? It does seem to be a bit technical. The pivot of the front bearing of the core machine is designed in a stator shape, and this design can also be counted as 0. 5-stage compressor design. There is also the combustion chamber and the turbine blades with a crown, which are all world-class mid-push core machine designs. ”

Everyone sitting here has more or less good knowledge of aero engines, and it may be a little difficult for you to design engines and core engines, but it is still very insightful to evaluate the quality of a core engine.

"Good thing, the technology used in this core machine alone is not comparable to the technology inherited by Hongqi Factory from the turbofan 9 engine, no wonder the experts of the review team were full of praise after returning to the imperial capital last time, and now it seems that it is indeed a famous person."

The importance of a core machine has been vigorously promoted by Southwest Science and Industry in recent years, and various domestic technical experts have visited and inspected Western countries.

Before introducing the entire engine program, the southwest science and industry hyped up the core engine, which was also very popular with these military, science and technology commissions, and technical experts.

"Our push core machine has undergone rigorous testing and testing, and the national finalization has been completed a month ago, which means that our southwest science and industry program has a high degree of completion. We are worried about the problems of the core engine in the development of the new engine, so we can say with certainty that our engine development progress has been completed by 30%. ”

As soon as these words came out, it directly hit the heart of the army and the Science and Technology Commission, which has completed the engine program of 30 percent progress, but it is not comparable to the plan of the Hongqi Factory that only has a general technical framework, which at least means that the engine development of the Southwest Science and Industry is two or three years faster than that of the Hongqi Factory.

Don't underestimate this little bit of time, often two or three years is enough to drag a very promising project to death halfway, this kind of experience is too much for the republic to think about.

The design of an engine not only depends on the design of the core machine, but also depends on the design of other system components, although the barrel effect is not very obvious in the design of aero engines, but as long as there is a technical shortcoming, this will still more or less affect the performance of the entire engine.

After making an introduction to the core machine, Chief Master Li wisely chose not to continue to dwell too much on the core machine, no matter how good your things are, you can't stand the constant bragging. There is nothing wrong with the so-called principle of top ten blacks here.

"Of course, the advantage of our Southwest Science and Industry program is not only the excellent design of the core machine, but also the design of the low-pressure rotor. With our strong ability in titanium alloy processing technology, we have applied advanced fan design to the turbofan of the new generation of mid-thrust turbofan engine: titanium alloy will be used as the blade material, and at the same time, we also use the ternary flow design theory of turbomachinery to design the wide chord fan blade.
