readx;?“ It would be nice to concentrate on completing the Secondary 4 project first, and if the situation continues like this. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 info The army intends to complete the development of the fourth generation first, which means that the fourth may complete the design and finalization work faster, and its status probably feels a bit like the MiG-29 fighter before the Su-27 was put into service, all of which are to buy time for the development of the real main fighter, and let the army be familiar with the operation of the fourth-generation aircraft in advance, and quickly fill in the gaps, probably this is the case, I said no problem, right? ”

The military can position the importance of the fourth level to this level, relatively speaking, it is more appropriate, and it still gives full play to the role of the fourth project, which is a good reassurance for the domestic military, AVIC Southwest, and foreign purchasers, after all, this aircraft is recognized by the military of the country that developed the project, so there should be no problem in general, and the purchase and use can be more secure.

For the fourth grade, in fact, Yang Hui has nothing to say, now there are both domestic military order commitments, and the United Arab Emirates waving the dollar to the side waiting, as long as the project does not have too many problems, it seems that there is a great possibility of success.

To say what level of performance Taihang's increased version can reach, Yang Hui is not very clear, but the thrust of this engine to 14 tons must be guaranteed, otherwise the middle four at that time may not even be able to achieve the F-35 level of pseudo-super cruise, at that time it will be all kinds of embarrassing situations.

The Taihang engine after the increase is used as the early power system of the middle four, but in addition to this, the fourth is not without other engine options, such as cooperation with Russia, the development of a performance-enhanced version of the 31F engine, whether it is to take the 99m1-m3 route, or to take the 117s route will work, anyway, the 31f engine is fully capable of achieving thrust increase.

After increasing the thrust of the 31F series of engines, this can temporarily meet the needs of the power system of the fourth, so the option of using the enhanced version of the 31F engine to make a middle four power system is completely possible, but if you really want to use the 31F engine as the power system of the middle four, then the opportunity to export abroad is very slim, which is not a good choice for the fourth grade.

Of course, if you want to say that the best choice for the fourth generation, it must be the best to use the fourth-generation high-thrust turbofan as the power, and only this thing is the standard configuration that the fourth-generation should have, but now for various reasons, I have no choice but to choose the improved version of the third-generation big push, and there must be many reasons for this.

For example, first of all, considering that the development progress of the fourth generation of Datui will definitely not be able to keep up, so the early stage of the fourth generation can only use the improved version of Taihang; For example, considering the needs of export sales, the best engines cannot be taken out for sale, which is just like when the United States exported the F-16 in the seventies, it did not sell the version that used the F-100 engine, but only sold the F-16-79 model that used the J-79 engine, which was to ensure that more advanced engine technology was not leaked.

Or from the perspective of the Taihang engine itself, now that the army has determined that the Taihang engine will provide the power system of Zhongsi, it is not the previous United Aero Engine Company proposed to add Russia to Ufa, and the two sides will cooperate to provide a 31F engine based on the production line set up in the Republic of China, which proves that China is looking for a turbine alliance company under AVIC Northeast to maintain the high-thrust military turbofan engine project.

The reason for this is that it may be necessary to hand over the development of the fourth-generation large-thrust turbofan engine to AVIC Southwest, after all, the performance of the fourth-generation large-thrust turbofan proposed by AVIC Southwest is advanced enough, and now the development of the heavy four is no longer so urgent, relatively speaking, it is necessary to rank the performance in the first place, which includes the competition of the engine is also to win with a better engine performance index.

AVIC Southwest won the fourth-generation large-thrust turbofan project, which is a great thing, but it is also a gamble for the military, the performance indicators of the fourth-generation high-thrust are too advanced, and this is a good thing to be compared to the F-119 engine.

In this case, the Taihang engine after the increase is also a good choice, in a sense, Taihang is not only a standard third-generation turbofan engine, but now the improved version is also related to the power system of the fourth-generation aircraft, so sometimes the spare tire is such a role, helpless at the same time, it can also be regarded as a panacea, widely dispersed network.....

In fact, the U.S. military did the same back then, after Pratt & Whitney won the F-119 engine project, the United States also awarded GM a contract for the overhaul of the third-generation turbofan F-110 engine, and finally gave birth to other engines, and these are all big guys with a thrust of up to 14 tons, which are even better than the engines that Maozi advertises all day long.

The engine is a spare tire for the F-119, this is no problem, a country as strong as the United States needs to prepare a genuine engine for its own fighters, but also to prepare a spare tire, the Republic of China, a country that has a more serious jump in the development of aero engines, it is even more impossible not to prepare a spare tire.

Since it is said that the problem of the spare tire, it is imperative to increase the model of Taihang, and since it is imperative, it must be taken into account that in case the fourth generation of the big push is smoothly promoted in all aspects, how to place the spare tire, if this aspect can not be properly solved, there will definitely be a big problem.

For the same spare tire placement problem, the United States finally gave the engine the ultimate improved use, which can be regarded as finding a good home for the spare tire, so that GM will not lose money.

Relatively speaking, now the Republic may have to go further, equipping the additional model of Taihang for the early version of the fourth for use, and may also use it for the follow-up J-11 series fighters, anyway, it is necessary for the additional model of Taihang to be launched, and the arrangement of the army should be the most reasonable now.

In fact, it is not a bad thing for AVIC Southwest to have a spare tire to use, after all, AVIC Southwest wants to be the first to finalize the service of the fourth, so the engine can only be equipped with an additional version of Taihang, and it has no other choice.

"The general situation is like this, the problem of the fourth power system is the decision given by the army after considering all aspects, you don't think too much, and the results of the fourth generation of turbofans will come out soon, whether you can win this project in the southwest of AVIC, now you should be able to guess a large part, so prepare well, this time to announce to you the four generations of the turbofan project, you are absolutely unexpected."
