The AL-31 engines were solely responsible for quite a few J-10 crashes. So the quality of Russian products is definitely in question ...
Either a bad engine or no engine
when you understand why J-10 continued using Al-31s when J-11 used WS-10s you will understand Al-31 was far more reliable than the Chinese engine
nonsense, single engine aircraft tend to have higher accident rates than twin engines, F-16s are prone to have more accidents than F-18s or F-15s
True. We should appreciate AL31 supporting China air force for so many years.
Many of the so called AL-31 you seen serve in PLAAF is in fact overhaul by Chinese themselves since the quality is so bad originally from Russia.
Yup. There was a IHS Janes report in 2010 which stated that the Chinese doubled the AL-31's MTBO through in-house upgrades. Even those upgrades weren't enough to prevent a couple J-10 engine accidents...
Cost effective of Russian engine is not good.
yes and Chinese are, so they buy Russian engines because lack of better engines of domestic origin
As if Chinese now still buy Russian engine...
they do they bought 48 spare 117 for Su-35s and they bought 1000 Al31s of course lick your wounds, Russia is already flying T-30s on one Su-57, if China has something better why do you buy Su-35? of course in the land Alice in wonder land was charity, specially as an old IL-76 can be re-engined with PS-90 but China is stuck with obsolete engines for Y-20 and still buys engines to Ukraine, but live in wonder land Al-31s that China got are designs from 1980 upgraded in the 1990s, Su-30MS are going to be upgraded soon with 117s and Il-76 with PS-90 have better performance than Y-20
There is no point beating the old news. China WS-10 are no CMF-56 equivalent from the 80s. They are much improve and upthrusted. Same as the engine currently used on Y-20. Your IL-76 fitted with new PD-90 still has an inferior smaller cargo bay and lower payload compare to Y-20 with current engine.
fantasy of Chinese forum, WS-10 is used mostly on J-11 for a simple reason a less reliable engine needs a mate if it fails on a single engine you need a more reliable engine because if it fails your aircraft drops, if China has better J-11 with Ws-10 why buy Su-35? in fantasy land for charity, but in real land J-11 has not better performance than Su-35,otherwise you will never buy Su-35 specially now China has TVC nozzles, and remember ARJ-21 and 919 use western engines none fly on Chinese engines but there are Tu-214 flying with Ps-90s.
I guess some is in denial mode.
minimum requirement was 24 at 2 billion Dollars 48 Su-35s equal 4 billion, why do not you make math instead of putting idiotic theories, China does not sell engines for fighters to Russia nor to the West, so far a more realistic person says China could not buy more because they are darn expensive and 100 would have been close to more than 8 billion, but of course stupidity can not accept reality, the whole Su-27SK/J-11 clone costed 2.5 billion dollars, 38 Su-30MKK were even cheaper, China has made advances and eventually they will catch up in some areas, but deny weaknesses are only for stupids, China is still behind the west, and Russia in aircraft engines, Russia too is behind the west in engines but they are much more capable than China at this moment, in fact J-31 has nothing near 135 engine used on F-35, they use two old RD-95 and in order to speed up the development they were realistic a 135 is decades away so they opted for two RD-93 and if lucky in the future they might have something domestic but one single 135 equals two RD-93 do you get it no one now has an engine as powerful to power a single engine aircraft, nor Russia even does, T-30 engine perhaps has surpassed 119 engine but still in tests and PD-14 is just nearly 1 year to be fit to MS-21, and if lucky by 2023 they might start making it with PD-14.
