More on AVIC conference keynote after translation:
In the seminar, Professor Liu Daxiang touched on these major milestones! The WS-15 official test acknowledgement was only just one of them and not the biggest news!!!
1) 3rd generation low-bypass turbofans (WS-10, WS-13, etc.) can be supplied completely with domestic models (least surprising since we've seen conversion to WS-10 with J-10C and J-20A and now J-15),
2) China's 4th-generation low-bypass turbofan engine WS-15 with TWR of above 10 has flown,
3) Next generation (5th-gen) low-bypass military turbofan engine projects have started for TWR of 12-15; next gen turboshaft engine for helis will have PWR of 11-12,
4) Turbine-based combined cycle engine/Turboramjet engine (TBCC) -- Chinese name for variable-cycle -- R&D has made major breakthroughs!
This is really the first official acknowledgement of a variable-cycle or combined engine project!
