Supercruise MACH 1,83?!
Maximum Speed MACH 2,5?!!!!
Clean Weight – 17 Tons ?!!!!!

Yea, with the intervention of god almighty or a massive breakthrough in engine technology and materials…
Those numbers are bogus.

No official specs have been released, and full potential won’t be met until WS-15 is ready. I don’t think the wait will as long as the J-10 specs but we will have to wait sometime for any official data. So until then they are all rumors.

Now thats one cool looking Light Combat Aircraft!

Ws-15 and Al-41 are both around at same level of development…..

I don’t understand, Al-41F1 (117) is already flying with the T-50. This engine has a max thrust of 147 kN. Then there is the Al-41F1A (117S) powering the Su-35. This has a max thrust of 142 kN. The next generation engine for the T-50 (170 – 180 kN ???) is under development. I think both Salut & Saturn are vying for this. But the AL-41F1 series is already flying.

ROKAF F-15K right out of the oven without CFT.

Are there any photos of this other flying J-20 with WS-10G engine and TVC nozzles:confused:

Or is it just as mysterious as the J-16 birdy claimed to be in development..

I am not convinced with WS-10G. A close inspection of the nozzle shows it looks a lot more like an AL-31 variant than a WS-10 variant. Member named maya at SDF (who seems to specialize in engines) said J-20 has an AL-31 variant and will do so until WS-15 is ready.

There is a difference between the PLAAF & PLAN WS-10. Whether it purely for long flights over the ocean (some added corrosion resistance thinggy) or whether there is a thrust increases I don’t know. The WS-10B powering J-10B prototype (1035) has higher thrust it seems compared the the baseline WS-10 in J-11B (132kN V 125kN).

Edit : There are other WS-10 variants planned, (up to 155kN) but I am just not convinced (yet) that the J-20 will use any of them. WS-15 is the required engine.

That WS-15 engine must be one Massive jet engine..:eek::confused:

Aviadvigatel D30-F6 turbofans, are rated at 152 kN thrust.
Given the MiG-31’s role as Mach 2.8+ interceptor and the sustained afterburning this requires, its fuel consumption is higher when compared to other aircraft serving in different roles, such as the Su-27. Consequently, the aircraft’s fuel fraction has been increased to more than 0.40—16,350 kg (36,050 lb) of high-density T-6 jet fuel.

Seems to me it has the be in the same physical size and weight as the D30-F6 engine..
Eighter that the Thrust specs is a tad optimistic.. Seeing is believing.

Their target is an F119 class engine (minimum 150 – 155 kN). Don’t for get YF119/YF120 came in the late 80s. Its 2012 (30+ years later), and WS-15 has flown only on a Il-76 engine testbed. I heard that it’ll take 7-10 years after the completion of high-altitude testing to enter service (2016 – 2019). So I don’t think its optimistic. This is why the current prototypes have AL-31 variant (rumored to be 135 – 140 kN). There is an image of the WS-15 core but you won’t see the full thing soon.

Quite right.
And i find it weird that some posters often claim that China are or will produce its own engines to replace the Russian AL-31FN(J-10) and AL-31F(J-11) engines, and yet we see more import orders.

It looks like the AL-31FN engine are at present time not going to be replaeced anytime soon.. If someone has any other source, pls show?

The WS-10 Engine series, however do replace the AL-31F from Russia, but at what rate? Are they to be installed on those Russian produced Flankers Su-30MKK/MK2?

This again :

Imported engines are manly for CAC projects. J-10 (AL-31FN), FC-1 (RD-93), J-20 (AL-31FMx? :confused:). There is one J-10B prototype flying with a WS-10B (1035) and an FC-1 prototype with WS-13 is said to be doing taxi trials, but I have never see any images. CAC don’t seem to be in a big hurry to get local engines or ones they require are not available. Unlike SAC, they have access to Russian engines specifically from MMPP Salut.

SAC, especially J-11B and variants WILL NOT get Russian engines. Russia is not contractually obliged in anyway to provide engines for J-11B, but they still send kits for the J-11A. So far all WS-10 engines have gone to J-11B/BS/BH/BSH, along with at least 1 J-15 prototype.

CAC will continue to use Russian engines, but eventually they’ll be replaced with WS-10 variants, WS-13 & WS-15. SAC has to use WS-10 & variants, PERIOD.
