Chengdu J-20 5th Generation Aircraft News & Discussions

this is for ws 15 ? would be amazing if true

I'm still sceptical and think it is more likely the J-20 fitted with a WS-10B3 than the WS-15.

How could you tell the difference if both engines use the same TVC nozzle?

the progress they make from ws15 should also help ws19 due to turbine blade improvements?

chineee TVC is 3D?

Well. It was Indian News Media that claimed that IAF SU-30MKI radar detected the J-20 on their radar.

As far as we know J-20 was never based anywhere next to India.

Yes, the Indian flanker is the only one out of all the flankers that has a radar that can reach all across Tibet from India to Chengdu!

The funny thing is India doesn't even use their own radar in the MKI but a Russian export model...

We’ve seen it in action over Zhuhai in 2018.

I cannot but from what we have seen it looks like the WS-10B3 and since when have ever two very different engines used the same nozzle? As such I expect the WS-15 to be vastly different to a WS-10.

It's clear that the TVC nozzle was never made with the WS-10 in mind, else we'd be seeing it equipped on fighters like the J-10C or J-11B. It was a one-off proof of principle, which is why I suspect the nozzle was made for the WS-15 and was just tested using the WS-10 since China had no other engine.

You're positing an entire new TVC nozzle for the WS-15 with no indication that such a thing has been developed.

@Deino I have a photo of the plane inflight!

Spoiler: WS-15 J-20?

Too blurry to make out anything. WS-15 is like the PAF + J-10C saga - there's always talk of an "imminent" reveal that has turned out to be nothing but a fairy tale every single time.

It seems you've uncovered it. There's no such thing as the WS-15, whatever shall China do?

Let's not be snide. The photo is too grainy to make out anything other than a supposed J-20 airframe, much less an engine that China has been working on for over two decades without much success.

That may very well be the case. However, I think that chances are high that my new born son will see it enter service in numbers before he reaches my age.

How are your Kaveri (engine ) project is going

Maybe I misread your reply but indeed I'm proposing an entire new nozzle, a nozzle that can be similar but surely not the same - at least like I read your post above - since just asked in return: Whenever was a nozzle from one engine mated to a completely different one?

At least i know no such case.

The WS-10 was the contemporary of the Kaveri. Today the WS-10 is powering everything from the J-11 to J-16 to J-10C to J-20.

The WS-15 program came much later but the witless Hindus are trying to sooth their own butthurt by hoping somehow it won't be inducted.

When the WS-15 is put on the J-20, a matter of time, then they will move on to the WS-19 and say why is it not inducted after "decades" because the initial J-35s will mostly likely use WS-13 variants.

Mind blowing that a people who never had an Indian engine power anything would be talking smack!
