How old is WS-10? Isnt it already years old? I thought that most problems were solved by now.

-Passed all milstone test only in 2008, certify to be used on fighter jet.
-Mass production started in early 2009
-PLAAF J-11B regiment reported poor quality of the serial production engine and in the late same year, WS-10 is grounded.
-WS-10 sighted being used on J-11 series fighter jet again in 2011
-Year 2012 sighted with WS-10 engine replacing traditional AL-31F engine used on prototype(J-16/ J-15S) for initial flight test. WS-10 continue to equipped on J-11 Series fighter.

WS-10 development started in 1987.

16 years and counting

Aside from less power output and shorter service life, compared to Western turbofans, the WS-10 is a fine engine.

China has made amazing advances in military sciences, truly unparalleled in modern history, but she hasn't solved aero engines, and it's only right to call them as we see them.

The engine was certified in 2008 (or 2006, I've heard both). That's not 16 years.

I am fairly certain your timeline is a bit off.

Development allegedly began in 1987, though it may have began unofficially as early as 1980 after the WS-6 was canned.

The high pressure components were successfully tested in 1993

The first complete engine was finished in 1997 but was so far from production that the J-10 needed to switch to AL-31FN.

Rumor has it that in 1997 the WS-10 had technical malfunctions, including throwing compressor blades. These issues took 2 years to resolve.

In 2000 the WS-10 received certification for flight testing.

In 2004 a WS-10 aboard the J-11 testbed had a bearing failure that nearly took down the aircraft.

In 2005, WS-10 completed full life endurance testing.

WS-10 received design certification in 2006, not 2008.

J-11B production started around 2007. Rumor has it that the first J-11B's used WS-10 but were quickly grounded due to quality control issues. Production then restarted with AL-31F until Russia stopped shipping them.

WS-10 entered mass (or at least some level of) production in 2009 and we began to see our first J-11B's equipped.

There is little reason to doubt that the WS-10 isn't in mass production, but it has taken China an awful long time. Even today, there is no evidence that the engine is reliable enough for a single-engine fighter like the J-10.

Given that China basically lept two generations of engine technology to get there, it's still quite an accomplishment.

WS10 beats its US counterparts the PW F100 & GE F110 in thrust & thrust/weight ratio & definitely in price.
Europe don't even have an engine in the class of WS10.
US ones likely have longer lives, but with worse performances, that's to be expected.
But that's no shame, F100/110 were developed earlier & don't have access to the latest tech.

You are STUPID or pretend to be STUPID ?? Western Engine ?

The ONLY countries with WS-10A class turbo fan engine are USA and Russia + China. UK with their "most advanced engine tech" does not even have a large turbo fan design on paper !!! France only has M-88 and it is a WS-13, F-404 class engine. Where did the "western" part coming from? Oh, just because USA has the best military engine tech, therefor all western countries have it ? It is the White man vs Chinese, right ?

WS-10A has 130KN of thrust compare to 129 KN for the PW-F-100 and 125KN of AL-31FN. Just because WS-10A has less thrust than the F-119 and 117 does not mean that is has less power ! WS-10A is more powerful than: RD-93, WS-13, M-88, EJ-200, F-414, F-404, AL-31F.................. You name it and the list goes on !!!!!

Where did the lesser power coming from ?

Shorter life ? Yes, true but all western engine and Russian engins have short life as well. F-100 has only 500 hour life in the 1970's, AL-31F had only 300 hours when it first introduced in the 1980's.

WS-10A now has around 2000 hours of life is a very big accomplishment.

This is why the Chinese are confident enough to develope the J-20, because they know that now have can build a F-119 class engine the WS-15.

Sure they might struggle a bit for it but at least they can get it DONE !!

You and your pathatic western RACIST can go post your prejedious comments all you want, it AINT gonna slow down China one bit !
