J-35A fighter (PLAAF) + FC-31 thread

Absolutely not. If you looked closer you would've found that the black nozzles are actually tri-layered and completely different from ones found on the J-35 (and RD-33/93). The outer petals are also very intricate, and similar in fashion to the F135.

I find both engines' nozzle being tri-layered except different shapes and lenghes of each layer. Three layers marked by yellow, red and green. The only difference is the middle layer (yellow) in the supposed WS-21 is shorter. When contracted in the case of supposed WS-21, the middle layer only appears as a strip or ridge, but you can still see the tip of it just behind the outmost layer's tip. See the markings below.

It is clear that availabe photos of J-35 and 35A have different nozzles, but nozzle alone does not tell anything about engines, just like WS-10 have even more variants of nozzles.

It is important to note that, most of engines have "three layers" of patels. The inner most layer is the CD nozzle, the outer two should be seen as one layer whose only purpose is to smoth out air flow. The "two layers overlapping" design is to make sure air does not go into the cavety between the divergent part of the nozzle and outer layer.

A properly integrated TVC imo offers much more than just better flips at airshows, such as:
-improved low speed control where the normal surfaces are least effective.
-reduced control surfaces area, so less RCS, less drag etc, Su-35 and especially Su-57 being prime examples, not to mention J-50 and J-36 that don't have tails at all.
-reduced RCS and thermal signature for the flat nozzled TVC variety.
This off the top of my head.
I mean, I’m actually a big proponent of TVC for all those reasons but if the gains are marginal relative to practical real world performance, especially if they can also come with tradeoffs, I can see why you might choose to defer on it.

Wasn't it said to have combat radius similar to early flankers by IIRC guancha a while back, which would be around 1500km?
interesting that I've now seen more photo and the 30t may be referring to J-35. It's possible J-35A is a little lower for MTOW at 27-28t. I guess we will find out more once the export campaign kicks off.

isn't CCTV confirmed J-35A MTOW is around 30 tons ?

CCTV reports: "Completely independent research and developed medium-thrust engine, MTOW close to 30 tons." "RCS is smaller than the palm of your hand"

It has not yet been officially confirmed whether it is the WS-19 or WS-21. Maybe it's both for now, after all, we all know that WS-19 is the target engine

IMO, if you look on WB. Yankee quite literally is the only guy who is considered credible claiming it's WS-19 while everyone else is either being careful with wording or outright denying it.
I would be careful with Captain小潇 and co.'s assertions. They're insisting that the WS-19 hasn't even test flown yet from the J-35/A yet this was already confirmed by multiple credible insiders, Orca, Monkey, etc.

Without airspeed and the lift from it, TVC won't be able to keep you in the air, forcefully turning the nozzle will get you crashed more easily than staying in the air. It is a common missunderstanding of TVC can do everything. TVC can improve instanous turn rate of nose pointing, but does not compansate lift at low air speed.
What about the supercirculation lift, though?

Based on the video, I think they are talking about J-35.

And also the comment about smaller than the palm of your hand is just to give people a rough idea of how hard it is to detect.

Wouldn't it be better than J20 vanilla and on par or less that j20A/S?
I think it would be good to not overthink this.

There are probably just going to be some natural advantages to J-20 since it's larger and have more power generation capabilities and more space for ESM for passive detection and such. There are just advantages to larger aircraft.
