The final bidding results of the four generations of turbofans in the waiting period have not yet come out, but a news that is not clear whether it is good or bad has arrived first, and it is also related to the field of aero engines, and it is still said that the engine used in the fourth generation aircraft, if the heavy four is the real son, then the fourth developed by the southwest Hongdu of AVIC is a typical concubine. Pen & Fun & Pavilion www.biquge.info

But fortunately, the current concubine has to take the first step in the dark knot, and the concubine's grandmother's family is still good enough, and now there is a variety of funds from AVIC Southwest to supply all kinds of funds, and it is also after putting together that there are enough funds to support the steady development of the fourth project, plus although this is just a concubine, but you can't stand up to other people's abilities in all aspects, so relatively speaking, it is quite likable, which is why there is a comprehensive investigation of the air force after the official start of the fourth project, and also give the project a certain amount of support.

It is precisely because of the partial support given by the domestic army that the positioning of the fourth is clearer at this time, and it can meet the requirements of the domestic army, and then various supporting projects can be steadily promoted in place, and this includes the power system design of the fourth middle school.

"The army means that now the engine model used in Hongdu Zhongsi has been completely determined, and the initial production of the fighter will use the additional Taihang engine, including the second half of the export after the use of the Taihang engine, which is probably what it means, right?"

Regarding the statement given by the army, logically speaking, Yang Hui still agrees with it, and there is no need to worry too much about whether Taihang will be like the previous one, at least from the news that Yang Hui has obtained now, Taihang in this plane is still relatively reliable.

First of all, the design of the core aircraft of this plane is very different from the previous one, and the republic's aero engine development system has also been more comprehensively developed, although most of these developments are from the various experiences of United Aero Engine Company, but such as the design of the engine, military standards, etc., these are the whole process completed by AVIC Southwest through the turbofan 12 engine project, and these are the hard design indicators after that, and extended to all aero-engine designs in the Republic.

From the design idea to the military standard regulations, there is a complete set of mature systems available, and there is also a complete set of supplier system established for the engine development and production of United Aero Engine Company, these hardware and software maturity will play a vital role in the development of Taihang engine in this plane.

Admit that the previous Taihang does have a variety of problems, but we must also understand the pioneering role played by the previous Taihang engine, at least before the previous Taihang engine, almost the Republic has not had a military turbofan engine that has completely completed the entire development process, so as a pioneer, the Taihang engine has indeed encountered a lot of difficulties, and the progress and reliability have been delayed again and again, and these are the reasons for the poor performance of Taihang in the early stage of the previous plane.

In the face of the specific new situation of the republic, Taihang is no longer the role of a pioneer, but has become a descendant who has followed the path that his predecessors have walked, and it is the feeling of belonging to the descendants to enjoy the cold. Two completely different circumstances caused the development of the Taihang engine in this plane to be smooth and smooth, and even the design and finalization of the initial model will be completed in a few years.

The design and finalization of the initial model will definitely be completed before 2000, so that Taihang is the only one that can be used in the Republic in the next few years to develop a self-developed military turbofan, and the fourth as a relatively hurry, but also to prepare to be introduced to the market around 2005 to compete with the European Shuangfeng market model, it is definitely too late to wait for the maturity of the fourth generation of the big push.

There is no fourth-generation high-thrust turbofan, which does not mean that the fourth is going to die, and the use of the performance-enhanced version of the third-generation large-thrust Taihang as the power system, this is also no problem at all, anyway, the fourth is to compete for the market with the European double wind, and use the low-profile version of the fourth-generation and the high-configuration version of the medium-sized third-generation + competition, which is no problem at all.

Yang Hui, as the head of AVIC Southwest, can understand the above meaning at once, so that he doesn't need to explain too much, and after nodding, he didn't say anything else, and continued to talk about the fourth secondary school directly on the topic.

"That's right, the military and equipment scientific research and demonstration departments also mean this, after the previous air friction confrontation in the East China Sea, the air force and navy unanimously believe that the heavy fighter is an extremely important project for our future, and now it is better to slow down the development progress of the heavy aircraft, but also to ensure that it can come up with a really good aircraft, to have the spirit of Sukhoi to develop the Su-27, is absolutely not blind and one-sided rush. However, in consideration of this, we have taken into account that the future navy and air force will indeed not be able to do without fourth-generation aircraft, so we have decided to concentrate resources on the development of the fourth middle school in Hongdu now. ”

Saying a thousand words and ten thousand, Yang Hui can be regarded as understanding what the real reason for this time is, the country and the army have changed their views on Chongsi. You must know that the previous ideas and requirements of the domestic air force and navy were: to speed up the research and development of the project, to ensure that it can have its own heavy fourth-generation aircraft as soon as possible, and to strive to be able to enter service soon after the F-22 enters service, so as to ensure that it will not be helpless when it comes to the heavy fourth-generation aircraft of the United States.

However, after the air friction in the East China Sea, China has discovered that the United States is not actually completely led by the nose, and many times the United States still considers its own interests more, which shows that in fact, the probability of China and the United States really launching a full-scale confrontation in a short period of time is very small, and it is precisely based on such an international security situation that it will definitely affect the development of such key projects.

So from the perspective of AVIC Southwest, this is actually a hundred benefits and no harm, the heavy four need to go to the mode of fine grinding, which means that the time of the heavy four project will be very long in the future, and even the development time left in the middle for the fourth generation of large push turbofan will also increase; From another point of view, it is mainly reflected in the fact that the fourth year of secondary school was officially supported by the army this time, and it can be regarded as getting a birth permit to enter the military.
