One more, this time a peek at the front instead of rear.
Interestingly, the F119 has 21 vanes, while the F135 had 17. This one? 19.

Just a nail in the coffin sort of the deal here. If you have enough thrust you definitely want to have good rearward stealth as well. If you do not it is something you need to trade off.
AFAIK so far none. TMCs are still considered primarily in the advanced developmental, testing, or niche production phases rather than widespread, standard commercial use, largely due to high production costs and manufacturing complexity. GE and Pratt & Whitney have focused on using fiber-reinforced TMCs for compressor rotors and blades.

Reminds me of a 2 stage LPC for the F414 also with a PR of 5:

Seems quite useful for ACEs given their lower LPC counts:
Oh and, quick note. I don't know how I haven't explicitly realised this but let's go back to 2022 when academician Huang Weina presented this:
We've seen this many times now and it serves as a rough ballpark for how much thrust the WS-19 makes, in this case, ~9,900 kgf.
Many would've said this is quite a bit lower than what we're expecting/I've said (~11,000-13,000 kgf), and in the past I've consistently pointed out that the data on the graph is actually just reflective of the tech demo (WS-X9). But what I want to say now is, look at this next slide:
In which it says, "需求满足率已超过90%." Of course, it doesn't say that it's talking about thrust only (or at all). But if we work this out backwards using ~9,900 kgf, then a 100% would be ~11,000 kgf. Which lines up perfectly with what was outlined 15 years ago:
Of course, I'm not saying these specs are completely reflective of what the WS-19 is *now*. But I'm just saying that I would be very comfortable saying, with confidence, that the WS-19 puts out ≥110 kN (not kgf, I'm going by the table).
This is already clearly established by credible rumours but I'm just looking at this via explicit, tangible official figures. Just haven't seen anyone explicitly making this link, so I'm putting it here.
P.S. The Guancha Trio did say it produces thrust 1.X tonnes-force less than the AL-31F (122.6 kN or 12,502 kgf. I'm 'guessing' ~115 kN at this stage). Lines up eerily well. And, I honestly expect the WS-19 to have improved on other aspects of the table now.
P.P.S. I still stand by the 12,000-13,000 kgf figure, but that might have to wait until the WS-19H.
P.P.P.S. Oh and it even lines up with this too (even if it's not explicitly stated to be written by AVIC officials. Coincidence maybe?
):
I'm pretty sure in the context here, they mean the product currently meets >90 percent of requirements in terms of amount of requirements met.
I'm pretty sure I've already written a disclaimer.
