J-10 Thread III (Closed to posting)

[Totoro]

Is there some timetable for production of j-10 available? Or at least entry of j10s into service with plaaf? When was that year that no new units were deployed? Is production continued now? Is it still around 24 pieces a year?

well, you might have noticed that we haven't really confirmed a new J-10 regiment for a while now, although the good folks at CDF seemed to have identified a new one recently. Because of troubles with WS-10A project and not signing any new AL-31FN project, they just couldn't produce any J-10s for that stretch from late 2007 to this year.

And they were easily producing 50 J-10s a year from late 2005 to 2006.

I heard XAC has less trouble mass producing the WS-15. so why not use WS-15 for the J-10 and J-11?

Ermm...what? The WS-15 isn't even out of development. Even if it were, it's not as simple as replacing one engine for another. Airframes are designed around different engines which have different dimensions.

In any case, if the production problems with the WS-10A aren't fixed, I doubt WS-15 will necessarily leap frog production problems. After all, production isn't handled by any one company, but a network of supply chains incorporating many different groups and factories.

Not necessay WS-10A problem exist then WS-15 can't proceed forward. They are different designs. They are running parallel.

WS-15 is about the same size but more power. Remember, Xian is producing Ws-15 whereas Ws-10A is mostly by shenyang. different groups you know.

In your expert opinion then, how many J-10/10A/10S does China have?

we are definitely sure about 4 regiments, so 4 x 28 = 112
and FTTC, around 20?
so, at least 132 and I think there maybe that new regiment that they found, which would bring the total to 140 to 160, depending on how far along the regiment conversion is.

I know the WS-15 is running parallel, but it hasn't even finished development yet, whereas the Ws-10A has theoretically already entered production. By the time the WS-15 is ready for production, problems with the Ws-10A's production would already be ironed out.

Also, just because the Ws-15 is relatively the same size does not mean it's dimensions will match the J-10. The J-10's frame was designed with the AL-31FN and the Ws-10a in mind. You can't just slap an entirely new engine on when the airframe wasn't designed to fit it.

any data about WS-15? was WS-15 new engine or improve WS-9?
WS-15 may turn out to be improve WS-9 (copy of spey 202 ) .

Not sure if it had been posted before, the link shows a ceremony held by Hong Yuang forging/casting factory (148 factory), 430 factory, and PLAAF representative for the delivery of some large forging parts of WS-15.
And according to the vice GM of 430 factory, the WS-15 is an "international" 4th generation engine.
If you read through the follow up comments, the #2 from the bottom, one guy (Hokly) claimed that WS-15 is based on Ukraine technology, and developped for L-15.

WS-15 is apparently the engine for the 5th generation fighter (J-xx), to try to match the F119 engines of the F-22...
I'm not sure where the ideas of an upgraded WS-9 first came from, apart from the "chinese engines" page on Wikipedia.
