Chinese Engine Development

Variable-cycle engine for China's next-generation fighter program?

The above photo is of a 7-page article published by the journal "Technology Reward" (科技奖励) in November of 2018 that contains an interview with Mr. Liu Yongquan (刘永泉), who is the chief designer at Shenyang Engine Design Institute. Unfortunately, I do not have access to the article. However, from

, I gleaned this tidbit:


Please help with the translation, as I'm not sure about how to translate the green part of the text.

Finally found more screen shots of the article on the VCE efforts by AECC Shenyang, which was the first VCE development program in China to successfully verify all key technologies.

The chief designer of WS-19, Huang Weina, has been nominated as a candidate to become an academician of the Chinese Academy of Engineering.

triple duct VCE demonstrator developed by the Institute of Engineering Thermophysics, Chinese Academy of Sciences, has completed high-altitude test bench trials. Compared to the baseline engine with afterburner, fuel consumption is reduced by 37.5%, and specific thrust is increased by 47%.

This is just the institute's own test project, not the highly classified project for the sixth-gen fighter.

Here's the gentleman responsible for the program: Mr. Xu Gang.

Some translations for all this would be nice, if anyone would be so kind as to provide them.

Speaking of France; it's sort of funny how the Chinese aero-engine industry is basically running circles around most of Europe given how the GCAP was stated to likely NOT include a ACE/VCE at all whereas we know that Chinese ACE designs are being worked on that will specifically power their next gen aircraft. France itself doesn't even have anything deployed that's comparable to the WS-19 or the WS-15 currently.

France basically has one mass-produced fighter engine and that is the medium M88. They don't have a heavy like the WS-10 or WS-15.

France is in no way ahead of China as far as military TFs are concerned. China builds more and across more categories.

I think this will become more pronounced in the future. Even France's lead in commercial engines is the results of a joint venture between it and the US for CFM.

I think it is a matter of time before China's material science and industrial overtakes them and the British as well when the next iterations of both military and civil engines occur.

Really the only engine industry definitely ahead of China will be the US but with the ability of China to prototype, test and manufacture far faster. With iterations and new marks improving things far faster, even the US is within reach in the coming decades.

Google Lens works pretty well

France doesn't even have anything comparable to a medium weight WS-19. There's a big difference between a 75kN M88 and a 110-116kN WS-19 (and potential upgrades).

003的舰载机三大件——15+35+600，几乎全部确定会换发

尤其是后面那俩

有关涡桨的大小篇暂时告一段落了，祝新发项目顺顺利利

very interesting here, so J-15, J-35 and KJ-600 are all changing engines. J-35 is kind of obvious. KJ-600 will be interesting since it will need a new generation turboprop engine.

Wait, changing engine to....what?

WJ-10 and WS-19 obviously
