during the 2006 zhuhai airshow,Liming (?) reported a new 95KN engine under develop .designate as WS-14. it is strongly believe that the mock up ,and equally mysterious engine seen at the 2008 Zhuhai airshow may be (may be) the WS-14.her inlet fan engine was obvious influence by RD-33/93
higher thrust variant of WS-10 also being develop,name WS-10D,max.thrust to 155KN
WS-13,clone copy of RD-93 took her first flight on october,2005...

the configuration of the 9500kgf thrust class turbofan consists of a 3-stage Fan without VIGV ,a 7-stage HPC ,each driven by a single stage turbine, a single annular combustor,a radial augmentor ,an AVEN nozzle and FADEC system.
this engine is derived from a base core developed by CGTE(No.624 institute) with a corrected airflow of 19kg/s class,T4~1650K and ∏hpc~7...

WS-12 program was terminated in 1999 due to lack of funding. this engine was derived from a base core having a corrected flow of about 15kg/s .

the picture below is displaying a series of core engines with the inlet corrected airflows in the range of 5kg/s to 30kg/s .
left to right:
5kg/s(WS-500,700kgf engine...),15kg/s(12A core),20kg/s(WS-13 derivative core),30kg/s(WS-15--T/W ratio 10)

maya, what do you think about the rumour that the improved variant of Taihang is getting canceled? I was under the impression that when 4th gen plane takes off, it would be carrying that type of engine.

It's getting canceled?? I find that hard to believe, after all, China will need an engine more advanced than WS-10a as a stopgap between WS-15

the engine doesnt have to be ready for the initial flight test.
but i am surprised that China would cancel such a project simply due to technical difficulties

They might have just decided that given the problems the WS-10 development was having to simply accelerate WS-15 development.

Not solely for the reasons of technical difficulties but there have been many projects canceled due to the excessive development cost overruns created by technical failures such as the the fate of the J-9, (original) J-11 and J-13 projects.

I doubt the improved WS-10 would just get cancelled, other projects are tied to it so it is a lynchpin project so to speak.
