I wonder if the Yak-43, or indeed the Yak-41 for that matter, have anything to do with those rumors of a new Chinese V/STOL fighter.

I am probably very late to this subject but I was hoping somebody could help me out. I am confused as to what the Yk-43 actually was, most sources say it was a development of the Yak-141 but with the NK-32 engine. Then the confusion kicks in, some sources say there would have been no lift-jets and that the forward vertical thrust would have been provided by air-bleed from the NK-32. Others say it would have retained the lift-jets. Which is these is true?

I've never read anything about the YaK-43 not having lift jets, but no source seems to identify what type they might be.
The forward "auxiliary combustion chamber" fed with NK-32 air-bleed is often mentioned, sometimes as a possible fit. I don't know where that would be located, I always assumed it was ahead of the lift-jets in the forward fuselage, but piping air and fuel that far forward and wasting internal space when you have lift-jets seems odd to me as does duplicating the role of the lift jets. Maybe it was intended as a trim device with the ability to provide extra lift at high TO weights?
The YaK-43 seems very sketchy, very little detail at all which makes me wonder how much of a serious project it was.
