J-20 5th Gen Fighter Thread VIII

Honestly, 606, guys, I'm not greedy. Just do a tad bit better than or at least as good as your original goal of 175 kN and I'm good.

It’s akin to J-11B first batch where they used AL-31. It is a transition phase so they can get the pilots up to speed with new capabilities.

Yep, and that'll solve 90% our problems just because>90% J-20A aircraft will be with ws-15.

That just seems like cope, truth is probably closer to WS-15 development ran into issues and is being further delayed for a unknown amount of time. PLAAF obviously wants WS-15 as hinted previously by people on Weibo and considering the alleged massive improvement I don't see why they would be so hesitant to switch if it is ready considering they had to retool the production and supply line for J-20A anyways.

It is obvious that the WS-15 is not yet mature enough. Moreover, considering that engines will not play a decisive role in BVR air combat, it is reasonable to continue using an engine that has been proven reliable.

Isn't it nice we can finally lay to rest those consternated worries from ancient Decembers long past.

Another one if I'm not mistaken ...

Yeah it's noticeably longer than even the WS-10C2. But without close-ups or images of decent quality it's quite easy to be uncertain...


And hey, no prototype bort number.

A quick, crappy comparison I whipped up based on one from @Deino. It's not perfectly to scale but it gives an idea as how the nozzles' lengths vary.

Something tells me the WS-15 is easily put on J-20A still sporting the WS-10C2. No redesign required.

Even at least one grey one was seen too

Now that we have WS-10C2 and WS-15 in the post above, can we confirm which engine model is this J-20A with the grey camo powered by? WS-10C2 or WS-15?

view from below the j-20a´s intakes appears to be less pointed on the sides.

Could just be subtle angle differences in the photos.
