I’m not sure. Last year, Pupu personally stated that the WS-10B has a thrust of 14 tons ... a fact further corroborated by the description plates at Zhuhai 2014. Perhaps there is some designation confusion? The original WS-10A had a thrust of 13,200 kg back in 2007 according to a academic paper written by Taihang’s designer Zhang Enhe ... so something doesn’t add up here.

Is this the technology Germany wanted to purchase?

There is a big news about engine in China for quite a few weeks:

According to senior fellow of China Academy of Engineering, Liu Daxiang, the R&D of WS-15 going smoothy and will be design-frozen (Chinese term for enter mass production) within 3 to no more than 5 years.

Liu is the most senior researcher in Aero engine department of China, and his opinions can turn into government policy, so he is quite reliable.

Juding by Liu's schedule, WS-15 will be on flight test this year or next year.

So from now on, anything we saw on J-20's new model or maybe even the existing model, could have trace of WS-15.

According to some insiders, some features about WS-15: WS-15 will be looked much more compact/finer crafted and much shorter than WS-10/AL-31F, and it have something called directed-flow control device or whatever (I dont know how to translate the tech term, it is not vectorized thrust in Chinese btw).

This is the most anticipated portion ...

Sounds like Fluidic thrust vectoring?

So J-20B with WS-15 in three to five years. About 30 years behind the US but still good progress. The previous generation engine was 40 years behind the US in the making.

I don't see a 30 years difference. You have to remember the F-135 (the world's premier aeroengine) is just an upgraded version of the F-119 ... and I'm pretty sure the WS-15 is somewhere in between both engines in terms of performance (especially given the Chinese experience with the WS-10 and Chinese material advancements). So the difference is more like 10-15 years for the initial WS-15.

Also we hope most importance WS-15 is improve life span, hopefully able reach at lease 3000 hours, US/Europe engine already have 6000+ hours life span.

China sets up research center for aero-engine, gas turbine

BEIJING, Aug. 1 (Xinhua) -- Beijing University of Aeronautics and Astronautics, also known as Beihang University, announced on Wednesday that it had set up a science center focusing on basic scientific research of the aero-engine and gas turbine.

"The Science Center for Gas Turbine was established with nationwide resources to support China's independent innovation in the core domain," said Xu Huibin, president of the university and the center.

The center was jointly established by Tsinghua University, the Institute of Engineering Thermophysics of Chinese Academy of Sciences and multiple major research institutions and enterprises in similar fields.

The center will focus on the fundamental research of the aircraft engine and gas turbine through exploration of core technologies, talent cultivation, and establishment of scientific facilities, Xu said.

The aero-engine has been a perplexing "pain" for China's aviation industry. China has included the aero-engine and gas turbine as part of the country's major scientific and technological projects.

In 2016, China set up the Aero Engine Corporation of China in Beijing, aiming to make it a world-class aircraft engine maker with own innovation.

The kind of Chinese developments that Trump is trying very hard to impede, at least to delay, currently, possibly at all costs in his latest economic warfare initiatives against China, reducing trade deficits is merely a pretext

An expert from the Chinese engine industry stated that in 2010 that China was 30 years behind the US in engine technology. They expect to eliminate the gap by 2040.

20 years behind the U.S after WS-15 is what those people from institutions generally believe``````its no easy pass mate, no short-cuts in turbo engine field

So J-20B with WS-15 in three to five years. About 30 years behind the US but still good progress. The previous generation engine was 40 years behind the US in the making.

the total number of J-20 and J-20A would be in 300 - 400 range, WS-15 fitted J-20B would have similar number in total
