" but why should I be a China-basher or why do some claim I wish any harm only due to my conclusion it uses a Russian originated engine?"
You got misled, I am afraid. I don't detected a China bashing bone in you. I admit. I have read a few of your published articles. They are highly neutral in tones, and you tell only a little of what you actually knew. I won't call you a "China fanboy". They got this impression may be because you knew so much, while they knew so little.
"Maybe those people are CIA (Chinese Intel Agency, I mean PRC spy) who don't want people to know about Chinese real capability, or maybe they are clueless. But just leave them alone. "
That's what I have been suggesting. They were ordered to do so. But the phase of
Strategic Deception is over, IMO. The war clouds are gathering over China and Russia and the rest of the world.
Strong deterrence, should take the center stage, to prevent war.
Massive number of the highly capable J-20, will be at the forefront, of this conventional force deterrent.
"Finally there are few who think it is a mystical hybrid or Frankenstein WS-10X based on the WS-10's core mated with an AL-31FN-nozzle + other certain modifications to fool us ..."
I am one of those guys. But let's get this straight.
1.) I think the prototype WS-15, that first flew on J-20, in 2011, was an engine with a WS-15 engine core,
not WS-10 core.
2.) It was not mated with AL-31FN-Nozzle. It was an original
3D TVC nozzle. made in China. Its external appearance
happen to look like the AL-31FN Nozzle.
3.) This similarity was not intentional, but incidental. It was not meant to fool anyone.
4.) The fact that many people
confused J-20's engine with AL-31FN, is no fault of the designers.
"Following nearly all others, here at PDF, the WS-15 has finished bench testing, and is ready to enter flight testing "soon""
Not "soon", but already done. The ground bench testing has already completed, over a decade ago. And took flight testing onboard of J-20 has taken place on
Jan. 2011.
The fact that WS-15's engine core, has entered ground bench testing, and meet all design parameters specifications, in 2005, is not just my personal opinion.
As I have mentioned earlier, an insider has revealed this ground bench testing, in a long article in China's
"Ordnance Industry Science Technology", 2007, Vol. 7.
"For China's New Generation of Fighters - A Study on China's High Thrust to Weight Ratio TurboFan Engine Core's Development"

It's safe to say, all the people here at PDF added together, don't know WS-15's engine core more than this engineer, who wrote this article and worked in this project.
