J-20 5th Gen Fighter Thread VI

[siegecrossbow]

But J-10 and J-20 continue to use AL31-FN series 3 engines. Nearly all Chengdu-made aircraft use AL-31 FN series (and the new series 3 is indeed a good engine, but the original Al-31 FN was arguably responsible for the tragic death of Captain Yu Xu and a number J-10A pilots). Only Shenyang J-11B and J-16 use domestic engines. If I see both J-10Cs and J-20s start using WS-10 series engines like the J-11B and J-16, that would be a huge milestone.

Yu Xi died due to a head on collision with another jet I thought. That particular incident had nothing to do with the engine.

The wall climber specifically referred to “twin dragons” in his original post. If he wasn’t referring to two J-20s he spotted then he definitely meant that both the J-20 and another J-10 variant are getting domestic engines.

So no TVC for the J-20 but it does have serrated nozles now. The J-10 looks like it has an AL-31 variant, but I guess it's a WS-10.

"行了" (Xing le) is a word play on "太行" (Taihang) and roughly translates to "[they] have Taihang now". So yes, both are equiped with WS-10.

However we need to remember, that there is NO confirmation on this engine, it was a theory I or we summed up some time ago.

I agree there's no official confirmation that we know of but if one were to google "AL-31FM2 J-20" we see that almost all sources say that that is the current pairing. Wikipedia's AL-31 page also says this, though the cited link is in Cyrillic.

Another thought I just had is that this could explain what seems to be the recent lull in J-20 production. While it makes no sense to hold off 2018/19 production for a 2025 WS-15, it would certainly make sense to hold off for this improved WS-10X version that was right on the cusp of being finalized.

agreed, as they might have to make a few changes to engine mounts and fuel/engine controls specific to the WS-10, and that could require some lead time.

Just for fun.

How long do you guys think Minnie Chan will report on this? Let’s have a bet!

I think around three weeks.

THE Milestone! Let's hope that's the case moving forward.

The way I remember it, Yu Xi ejected from her problematic jet and got hit by another jet coming from behind. It wasn't any kind of maneuver mistake.

行了 in Chinese means “good to go” or “all set”. As to any hidden meaning, I can’t say...

I think they were flying in close formation when a mistake was made and Yu's jet collided with another jet, so she and her co-pilot ejected but she was struck by the wing of another jet as she ejected. It had nothing to do with the engine.

Only the original poster knows if he/she want to have a hidden meaning. However, the likelihood is very high. There has been a trend among Chinese netizens born since the 1980s, especially 1990s to use a noun in place of verb, or the other way around. 行 is both a noun as in "Taihang" and a verb as in "Xing le". The poster could be just playing the game if he is a young fellow. The other example is 雷了, where 雷 is the noun meaning thunder, but used by netizens as a verb as "shocked" (by a thunder).
