"The problem does exist, which we also admit, the J-18 engine used in the J-18 is two 9-ton thrust turbofan, now it seems that it is dragging down the thrust-to-weight ratio of the whole machine, but this will definitely not be a problem that has always existed and cannot be solved, as the turbofan 12 engine developer, United Aero Engine Company is making further improvements to the design of this engine, the next stage of development is to improve the engine to the thrust-to-weight ratio of 9 levels, and the thrust can reach the maximum afterburner thrust of 10 tons.

Anyway, soon Embraer will also announce the new generation of lightning fighter performance improvement and upgrade at the Paris Air Show, so that it can carry the JAS-39 Gripen fighter that is about to complete the finalized design and enter the international military fighter market, and the performance upgrade plan of the engine will definitely be announced at that time, and the design of the turbofan 12B will definitely be made public, and now Yang Hui will be blunt with the UAE.

As Yang Hui expected, after hearing that the developer of the engine has begun to upgrade the engine performance, this is very good news, which at least means that the J-18 is still likely to have a turbofan engine with excellent performance as the power system, and the thrust-to-weight ratio data of this aircraft should be slightly better!

There were only three UAE personnel who participated in the talks, and the three of them did not hesitate to connect and communicate briefly for a few minutes, and then they made a decision: "The engine used in this aircraft is about it for the time being, and we are relatively clear about the specific situation, so we mean nothing to worry about, after all, this procurement is not a fighter dedicated to air combat, and a lower thrust-to-weight ratio is actually acceptable, but how long will it take for your 10-ton improved model to complete the design?" ”

can ask about the progress of the 10-ton medium push, which still shows that the oil tyrants in the UAE are very interested in the J-18, otherwise who will care about the development progress of such an engine, people will directly choose another aircraft, and the J-18 will be directly out.

But it was when such a question was asked that Yang Hui felt even more embarrassed, and in terms of the development progress of the turbofan 12b, I am afraid it is not very optimistic.

"I also tell the truth here, before the development of the initial model of the turbofan 12 in 93 years to complete the finalization work, although we have completed most of the new technologies in the turbofan 12b engine improvement plan, but this is far from enough, we need to carry out a new design of the engine control system, and there are some new upgrades and improvements to the core machine, so the cold end components also need to be re-tested after the core machine is adapted, It is expected that the engine will not be finalized until about 98 years at the earliest. ”

Yang Hui's words are definitely not alarmist, although at this time he is only talking about the turbofan 12B engine, that is, the J-18 standard power system technical requirements in the original plan, but is the thrust-to-weight ratio of the 9-level thrust engine very hanging?

A 10-ton thrust engine can really meet the needs of the J-18, a quasi-heavy multi-role fighter that is already comparable to the F-15? The J-18's straight-wing design must be maneuverable in terms of maneuverability, so can the J-18 only be a multi-purpose ground attack aircraft? Can it really only be like the F-18, a fat and bloated bug with no mobility to speak of?

In view of the above problems, the only and most simple and crude solution to the problem is to carry out a real thrust-to-weight ratio of 10 levels of turbofan 12 engine after the turbofan 12b to improve the turbofan 12c, and only in this way can it be regarded as a real technical solution. At that time, it is necessary to add a three-dimensional axisymmetric vector nozzle, and realize the integrated cross-linking design of fire flight and push, etc., and at that time it can be called a real multi-role fighter.

As for whether the turbofan 12C engine at that time can be approved for launch, and whether the final version of the J-18 multi-role fighter will have the military guarantee procurement, it is probably another matter, after all, many times even if it can be done in technical engineering, but the success of the project is not only based on technical capabilities, market demand is also another issue that needs to be considered, which is probably the reason why the F-414EPE engine did not come out in the end.

But no matter what the end is, at least this time the push ratio 9 first-stage turbofan 12b engine is definitely going to be made, this is the standard power system design of the J-18, before the turbofan 12b was installed, the J-18 was definitely no problem as an attack aircraft, but when it comes to air combat capabilities, even if it is with the third-generation aircraft J-18 aerodynamically good at ultra-low-altitude and low-speed dogfight combat, I am afraid it may not be able to take an absolute advantage, as for the medium-range bullet but the shooting, it must be another matter.

For the turbofan 12B engine used by J-18 will not be completed until 98 years at the latest, the oil tyrants actually have their own considerations, for these time problems, the oil bully actually does not care too much, after all, this long-range strike fighter project was originally planned to be a special for the UAE to improve in depth, and specially customized model, which is the same regardless of which company provides the model.

"It will take at least 98 years for your engine to complete the finalization test, which means that it will take at least about 2000 years to complete the finalized design work for the newly launched J-18 fighter, although this is not unbearable, but we can't wait for five more years just to upgrade the performance of this engine, since we have waited for this long time, your new J-18 must also have a new improved design, right?"

I have to say that this UAE oil bully is really different from other oil tyrants in terms of knowledge, and if you think about it carefully, it must also be the same as the UAE has been holding since 87. Due to the air show, this plane of AVIC Southwest also participated in the first Dubai air show, when the military fighter order signed dozens of Saudi Arabia to support Yemen J-74/J-7A, and later signed several orders for a total of nearly 100 MPC-75 passenger aircraft.

It may be precisely because of these reasons that with the passage of time, the UAE has really cultivated a large number of more knowledgeable "professionals" in the aviation industry with the change of the environment, but in this way, it is actually better to talk about the project, anyway, the UAE only talks about technology and does not talk about price.

Now this group of oil tyrants in the UAE is probably more like personal PC enthusiasts, rich, a little bit of professional technology, and all kinds of high technology in the industry, so when the demand proposal was released, it was specially requested to be customized for the needs of the United Arab Emirates, which made it clear that it was the top configuration!

Think about it when the computer enthusiast pretends to be forced, it is the Titan, i7 must be on, water-cooled, two-way, crossfire or something of the top pretending architecture can not be less, so when the oil bully plays military fighter DIY, AVIC Southwest can also give him the top, anyway, as long as the configuration you give is enough to hang the bomb, our oil bully is poor?
