J-20 5th Gen Fighter Thread VI

Sorry , if irritating, just want to ask,
as everybody here did not know what exactly China progress in ws-10 series, how did you know it is an engine by China, not Russia's new engine specially made for China as a result of SU 35 contract?

Because if you look at the inside of the engine nozzle, there is the ring with small triangular flaps that is nothing of any AL-31 or derivatives.
See AL-31 FM2

then WS-10, see the triangular flaps hanging on the top side of the inner ring?

F110 for reference

Are they the same pair of engines? The earliest one had serrated nozzle tips but seems to be still axisymetrical, while the recent pic clearly shows sharp ridges running down each petal. The way their surfaces reflect light is noticeably different.

Probably the same nozzle but maybe the earlier release was heavily edited or incomplete.

Which version of WS-10 is being put on it?
Also what's the latest news on WS15?

I'm going to nitpick and say they got the contours of the back wrong.

Or there are 2 prototypes with 2 different pairs of LO shaped WS-10x units. But I'm not up to date with j-20 spotting. It could be the same prototype trying 2 different pairs of engines or just bad photo quality.

From Jane. Interesting they say PLAAF plan to procure 100 J20A and the engine thrust is 140Kn. Not sure how reliable is the new

Images have emerged on Chinese online forums showing what appears to be China’s J-20 'fifth-generation' fighter aircraft possibly equipped with new turbofan engines.

The images show the engines featuring revised nozzles, possibly for thrust vectoring, which may be used to power a new version of the Chengdu Aircraft Corporation (CAC) J-20.

Some of the most distinctive visible features of the turbofans include pointed nozzle petals designed to increase stealth: a feature that is characteristic of the US Pratt & Whitney F135 turbofan engine that powers the Lockheed Martin F-35 Joint Strike Fighter.

Although variants of Chinese Shenyang-Liming WS10 Taihang engines were used to power J-20 prototypes, the production variant of the aircraft appears to have been powered by a version of the Russian Saturn AL-31FN turbofan, feeding concerns that initial versions of China’s only ‘fifth-generation’ fighter could remain dependent on Russian engines and associated technology.

In March, state broadcaster China Central Television (CCTV) stated the aircraft had already entered service with the People's Liberation Army Air Force (PLAAF), although it is thought that only small numbers of the aircraft have been produced.

According to information revealed at the Airshow China 2014 exhibition in Zhuhai, the Liming Engine Manufacturing Corporation developed an improved variant of the WS10 turbofan that might have a thrust of more than 140 kN.

In late December 2016, the Hong Kong newspaper Ming Pao reported that the People’s Liberation Army (PLA) planned to initially acquire up to 100 J-20A variants, expected to be powered by an advanced version of the WS-10 or the AL-31 engine.

Ming Pao also reported that the PLA would then purchase up to 400 of J-20B version, expected to be equipped with a turbofan thought to generate a thrust of 145 kN, enabling a ‘super-cruise’ speed capability without afterburner.

It's Rich Fish citing Ming Pao. Keep your salt shakers close.
