If you want to argue that the Russians have lost their minds and they're passing up this terrific opportunity to advertise their AL-31 engines then there's very little that I can do to change your mind. In effect, you are claiming that your ability to recognize an AL-31 engine is superior to the Russians. I am sorry, but few objective people believe that.

Note: I am uncertain about the engines in the picture of the J-11 in the "photographic analysis." Two years ago, there were reports about uncertainty regarding the type(s) of engines that were being tested. However, it is two years later and most observers believe that the engines are improved WS-10s.

Yes I do ! ... and again I'm questioning the reliability of several "Russian" sources, which often claim a lot ... and have a very low credibility.

Come on ... an apple ia an apple even if some Russians might say it's an orange, since they were capable to make oranges looking like apples.

Just show me any WS-10A HT-powered Flanker with a nozzle that looks like a AL-31F-powered one ???

There is none even if some "Sources" claim that Chinese were capable to built the TH fitted with the AL-31's nozzle ... but why then do all other TH-powered one doesn't have that one ?

Why is it that when anyone questions anything about the WS-10, you spit all over them? The fact is that the J-15 doesn't use WS-10 right now, that is it. Anyone with eyes can see that. There is still no adequate explanation for why the J-15 still uses AL-31F. I really wish we did know. I am waiting for the WS-10-powered J-15 too.

I think I read sometime back in the Flanker thread (or possibly the J-20 thread) that there seemed to be indication that the AL-31F may have been reverse engineered completely (can't remember which specific engine company did so) and that China was capable of making indigenous AL-31Fs (which is a pretty spectacular feat) without any Russian assistance. Perhaps these AL-31F looking engines on the J-15, are Chinese built AL-31Fs?

Unlikely. I have thought about that before. Seems redundant to have both AL-31F and WS-10 projects going simultaneously. Some people have insisted that they are using AL-31F on the J-15 because the WS-10 isn't corrosion-proofed. Maybe it does need corrosion proofing, but the point is that argument doesnt hold water because the AL-31F itself isn't corrosion-proofed. Nor is there any reason to believe that the prototypes will ever see usage on a carrier with extensive exposure to sea air where it would need to be corrosion-proofed anyway. It really makes little sense.

But we also have report about maintenance depot in Sichuan that can extend the life of AL-31 from 1000 hr to 1500hr Remember China do their own maintenance. This maintenance depot is so good that they openly commended the director with certificate I have the picture of this depot. So it is not inconceivable that they can copy the engine or nozzle petal. I mean if they extend the life of the engine that mean they replace some of the part with their own design

But again ... why should the produce two different sets of WS-10 with different nozzles, one regulkar TH-like and one AL-31F-like ???

Only to fool us here ??

Hmm, the lady's voice sounds familiar, like she somehow is always at the scene during those video shots.

I notised the prototype (second aircraft) did not use afterburner during the takeoff, just like what happened with the J-20 prototype. The first aircraft took off with afterburner right from the start but both aircrafts seem to leave the ground at around the same spot. I'll have to see the video again to see which aircraft have the shorter takeoff.

I think the first aircraft had a faster rate of climb.

That's because the aircraft was on afterburner with the resultant higher thrust. The aircraft's takeoff speed was also noticebly faster than the other aircraft.

Russian media said that China-made J-15 carrier aircraft with WS-10A engines

Deino, you seem to care strongly about this issue. However, as a neutral observer, I simply follow the available facts and arrive at the most reasonable conclusion. There is another newly published article, which also claims that the J-15 Flying Shark is using WS-10A engines.

According to my count, I have cited Chinese Military Aviation, Defense Update, and Military of China. Try to keep an open mind. While I have not discounted the possibility that you may be correct, the current majority opinion is not in your favor.

...
Russia on April 27 reported that China is actively developing and testing a variety of new fighters, increasingly in the media-related news more. Recently explicitly noted that the Chinese developed the domestic “Shi Lang” aircraft carrier to carrier carrying platform F -15 fighter made WS-10A engine to use is actually a modified imitation of the Soviet Union -33, basic performance may be roughly equal."

[Note: Don't worry about the J-15/F-15 nomenclature. For example, one domestic Chinese fighter is named a J-7, but the export version is designated a F-7.]
