Chengdu J-20 5th Generation Aircraft News & Discussions

Not with such high speed on that turn.

Why for higher thrust engine needed if such move can be execute by AL-31F?

The turn execute by J-11BS is slower compare to J-20.

Your comparison is way off: First this particular J-11BS is exactly flying the type of engine You are erroneously claiming to power the J-20. So if the J-20 should be powered by the WS-10, then the Flanker which is for sure using a WS-10 should do this as well.
Second, we know manoeuvres from the Flankers using exactly the same type of engine You hate so much, namely the AL-31F which is IMO used by the J-20, that make all spectators hold their breaths ... as such, there is no need to use a higher thrust engine.
Third, therefore - and that's why such airshow demonstration videos are simply not suitable: they show aircraft in not the same conditions, You don't know the intention ... We don't know the particular weight of both aircraft. Were they fully fuelled or only loaded for a demo?

In consequence, You are claiming this particular J-11BS is using a weaker engine and therefore the J-20 has to have a higher thrust one ... the funny thing is only that exactly Your example Flanker is using exactly the engine You claim to power the J-20.

J-20 is using WS-10B not WS-10A. Did you forget? WS-10B is 14000kg thrust, reported by AVIC Lin Zuoming. WS-10A is 12700kg thrust. Deino, I think I do not need to remind you of this?

Maybe you want to claim 1300kg thrust is not significant?

Wrong again ... but I'm repeating myself - the WS-10B is the J-10B/C-tailored version with the gearbox on the bottom - and even more this report itself does not confirm this new engine

China may succeed in developing “Taihang” FWS-10B aircraft engine ...

IMO far from confirmed.

BY the way, these 13kN of extra thrust is indeed not bad but with a thrust of 140kN it is "only" 3 kN more than the official 137 kN the AL-31FN Series 3 delivers. And these 3 kN are not that much.

Anyway, we both will never agree on this issue as it seems... but I'm sure, time will tell.

That is nonsense. WS-10B is a designation also know as Ws-10G of 14000kg thrust. 14000kg max thrust is comfirm by AVIC president Lin zuoming during a interview. And by Feb 2016, they reported the breakthrough of domestic upgraded engine though they didn't specific exactly what type. The timing fits well of the engine ready for production which means fitting in those LRIP J-20 near year end perfectly makes sense. As for 14000kg is max thrust, we couldn't really know the dry thrust upgraded. One thing for sure, it's a significant upgrade.

And for the AL-31F series 3, you are the one talking about skceptical of such engines exported to China or even exist and now you claim such engine is fitted on J-20 or J-15?

You can check my previous posts, I made a fair comparison, but some people still want to ignore it on purpose.

Let’s make a bet on this.

I bet all J-20s we saw so far (2001, 2002, 2011, 2012, 2013, 2015, 2016, 2017, and several LRIP ones) are now using non-domestic engines and J-20 will enter service with non-domestic engines. I will cease this account If I lose.

Deadline: A credible direct participant or an official documentary of Project 718 confirms the suggestion of either side.

Who's in?

No one dares to bet against me?

I'll bet you that the FC-31 v2.0 will never make an appearance.

Anybody want to venture a reason why there is no official picture of the WS-15 or a model of the WS-15. I don't why know such secrecy is needed, since we already have pictures of WS-10 many years..

Besides our no-agreement You not even notice the flaws in his argumentation ??

That's indeed a funny issue. If You listen to my ongoing "discussion with @Beast, @pakistanipower and @ChineseTiger1986 they at least seem to have some final doubts. But anyway I'm sure time will tell even if I'm living in phantasy-word.

Maybe simply since there is no engine yet assembled and tested as a full engine ? Maybe since it is deemed too much top-secret to show ???

I doubt the WS-15 hasn't been tested yet. The project was started in late 1990's. The new metal alloy was ready a long time ago. China has accumulated vast experience in the WS-10 project. This was a hard earned experienced since many aspects was started from scratch. If it's true that the engine hasn't been extensively tested yet, its progress is grossly behind J-20. Somebody would be shoot for that. You can't tell much by just looking at an engine, the importance is in the details. So, I am wondering why so stingy with the picture?

With due all respect sir, their is 400+ WS-10A and B engine is operational so it is possible that they put high thrust variant on J-20 what flaw care to explain? you saying that China can't innovate its WS-10 series because your German ego can't accept that fact china put WS-10X in J-20, i think in future when J-20 will come out with WS-15 you will say that this is not a WS-15 but a AL31FN3

The US can still brag in front of China in some areas, but nobody else can.

Germany is good of making the diesel engine, but the turbofan/cryogenic/turbine technology, they are just a toddler in front of China.

Just like it would be ridiculous for the Chinese football to laugh at the German football because they just got one world cup champion less than Brazil.
