"First focus on the completion of the four projects, if the situation is so developed, it is very good."The army intends to complete the development of the fourth, which means that the middle four may be faster to complete the design and shape work, its status is probably a bit like the MiG-29 fighter before the Su-27 service, are for the real main fighter development time, and in advance to let the army familiar with the operation of the four generations of aircraft, and quickly fill the gap, probably this is the case, I said no problem?"

The army can position the importance of the four to this level, relatively speaking, is more appropriate, and still give full play to the role of the four projects, which for the domestic military, AVIC southwest, and foreign buyers, is a good peace of mind, after all, this aircraft is recognized by the military of the project development country, so it should be no problem, the purchase and use can be more secure.

For the fourth, in fact, Yang Hui is not much to say, now there is both the domestic military order commitment, and the United Arab Emirates waving the dollar in one eye waiting, as long as the project is not too big problem, now it seems that there is a great possibility of success.

To say what level of the push-up performance of Taihang can reach, this Yang Hui is not very clear, but the thrust of this engine to 14 tons must be guaranteed, otherwise the time of the four I am afraid that even the F-35 level of the pseudo super patrol is difficult to achieve, that time is a variety of embarrassing situation.

With the addition of the Taihang engine as the pre-power system of the fourth, but in addition to the fourth is not without other engine options, such as cooperation with Russia, the development of performance-enhanced version of the 31F engine, whether it is to take the 99M1-M3 route, or to take the 117S route are able to do, anyway, the 31F engine is fully capable of increasing thrust.

And increased after the thrust of the 31F series engine, which can temporarily meet the power system needs of the four, so with the 31F enhanced version of the engine to do a four-power system option, this is completely OK, but really use the 31F engine as the power system of the four, then the opportunity to export abroad is very slim, this is not a good choice for the fourth.

Of course, to say that the best choice for the four, it is still necessary to use the four-generation thrust fan to do the best power, and only this thing is the standard configuration of the four, but now for various reasons, it is helpless to choose the improved version of the three-generation push, as for which there are certainly many reasons.

For example, the first is to consider that the development progress of the four generations of the big push can certainly not keep up, so the fourth can only use the too-too-good improved model in the early stage; and for example, considering the needs of export, the best engine can not be sold out for sale, which is like the United States exported F-16 in the 1970s, does not sell the version of the F-16-79 engine using the J-79 engine, which is to ensure that the more advanced engine technology is not leaked.

Or from the Taihang engine itself, now that the army has determined the power system provided by the Taihang engine to provide the fourth power system, rather than the United Airlines engine company proposed by the Russian Ufa together, the two sides cooperate to provide a 31F engine booster based on the production line in the Republic, which also proves that the domestic is in the northeastern turbine alliance company to find a high-thick military turbofan engine project to maintain the errand.

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

AVIC Southwest won four generations of big push turbofan project, which is a good thing, but for the military side is also a gamble, the performance indicators of the four generations of big thrust are too advanced, which is a good thing to be comparable to the F-119 engine, to say that worried about the development of the engine will not jump ticket is certain, so this time to find a domestic spare tire for the four is also logical.

In this case, after the push of the Taihang engine is also a good choice, in a sense, Taihang is not only a standard three-generation turbofan engine, the current improvement type is also related to the power system of the four generations of the machine, so sometimes the spare tire is such a role, but also at the same time can also be regarded as a gold oil, wide net ...

In fact, the U.S. military did the same, after the Pratt & Whitney won the F-119 engine project, the United States also awarded the general change three generations of large-scale turbofan F-110 engine contract, and finally gave birth to the F-110-GE132134 engine, and these are the thrust of up to 14 tons of big guys, compared to Mao all day publicity 99M3117S engine even better.

F-100-GE132134 engine is F-119 spare tire, this is no problem, strong as the United States such as the United States need to prepare a real engine for their own fighter, but also to prepare a spare tire, the Republic in the development of aero engine ticket more serious countries, there is no possibility may not be prepared for a spare tire.

Since it is about the problem of spare tires, then the addition of the Taihang model is imperative, and since it is imperative, it must be considered that in the case of four generations of big push in all aspects of the smooth progress, how to place the spare tire, if it can not be properly solved, it will certainly cause a big problem.

The same spare tire placement problem, the United States finally gave the F-110-GE132134 engine to the F-16 and F-15 the ultimate improved use, is to find a good home for the spare tire, so that the general side will not lose weight.

Relatively speaking, now the Republic may have to go further, the Taihang's push-up model is equipped with the early version of the four, and may also be used for the subsequent J-11 series fighters, anyway, the promotion model of Taihang is necessary to launch, and the arrangement of the army should also be the most reasonable at present.

In fact, can have a spare tire to use, for the southwestern of China Airlines is not a bad thing, after all, the southwestern of China Airlines to pre-determined service four, then the engine can only be equipped with too-fast push-up version, the other it has no choice.

"Presumably this is the case, the problem with the four-year power system is the decision given by the army after all aspects of consideration, you don't think too much, and immediately the results of the four-generation push turbofan will come out, you can take this project in the southwest, now you should be able to guess a large part of it, so be prepared, this time to announce to you the four generations of big push turbofan project people, you absolutely unexpected."
