:D WS10 is officially open in Zhuhai air/space show!

http://war.163.com/06/1025/16/2U9U7MA700011232.html

the main indication of aero engine is thrust/weight ratio(T/W).
generally speaking,the more T/W the engine has ,the more advanced the engine is!
here is the officially open performance indication of Chinese WS10 and other engines from U.S,U.K,france and russia.
nation/ engine/ the aircrfts/ T/W
russia/ AL31F/ variety of su27/ 7.14
U.S. / F110-GE-129/ F16&F15 / 7.28
France/ M53-P2/ M-2000/ 6.56
China/ WS10/ J10&J11/ 7.50
U.S/ F119-PW-100/ F22 / 10.0
China/ Improved WS10 (unopen) 9.50
Judging from T/W ,Chinese WS10 for J10&J10 is slightly better than the counterparts on Flankers,M2000,F15 and F16.
but it still much lag behind the counterpart of F22.
the "improved WS10" is still under developement.I think it should be developed for "Modified J10"(super 10 so called) and still needs 5 years to roll out!

the first engine with a T/W of 7.0 in the world rolled out in U.S in 1970's
it took U.S 15-20 years to improve the T/W of its engine from 7.0 to10.0
but WS10,chinese first engine with a T/W of over 7.0 ,rolled out last year.
So,it is a long way for china to catch up with U.S.the first engine with a T/W of 7.0 in the world rolled out in U.S in 1970's

How good an engine is is measured by more than its thrust to weight ratio. How about durability? Reliability? Maintainability? Specific fuel consumption as said above? Response timing? Susceptibility to flame outs etc? Cost? Some factors wouldn't even have been reflected in those numbers. Look at the F119. It was optimised for supercruise, and hence sacrificed absolute thrust. The F135 which is based on the F119 didn't have such a constraint and it got its thrust boosted to beyond 40,000lb.

I quite agree with You.
I picked SFC because you can boost thrust/weight by abusing fuel efficiency - afterburner is an example that springs to mind.

According to the original plan, there would be a formal declaration of WS10A during the ZhuHai Airshow. It's printed on the official agenda. But it's cancelled and replaced by some vague news report. The more interesting graph about the future turbo fan engine dev roadmap was covered as well. J10 flight show was cancelled as well.

Disappointing

As I remarked on the other thread:
After a look at the picture of the J10
http://china-defense.blogspot.com/

The intake seems to be on the decidedly small side, which militates against a significant by-pass ratio - if any.
A pure jet can have a good thrust/weight ratio, but not with a good specific fuel consumption.
Furthermore I fail to see any big throat bleeds, which might indicate a very long take off role for full load.
Again the inlet seem to the 1 chock kind which functions well only under very special conditions - dogfighting not included.

We don't need our brown trousers for this one.
