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 !
