Z-20

Ah, not if Huitong confirmed that Z-20s are equipped with WZ-10s, which he did as early as 2018, as I have previously pointed out.

Do you seriously have trouble grasping the following simple facts from Huitong:
1) In-service Z-20s are currently equipped with domestic WZ-10 turboshafts.
2) A different domestic turboshaft (namely WZ-11) might be equipped in the future.

Just how did you interpret 2) to mean "the engine of the Z-20 is still unclear"?

You don't understand my logic because you don't understand logic, period.
There is nothing on Huitong's

that says the Z-20 is confirmed to have WZ-10s. If anything, there is quite a bit of uncertainty as to what the actual engine is. Please point out specific quotes from Huitong's latest entry that would suggest point number 1? Regarding point 2, why would a WZ-11 be equipped in the future if the WZ-10 has a thrust rating of 1600 kw, while the WZ-11 only has a rating of 1500 kw according to Huitong.

Surely this should show you that the engine used was still not confirmed, contrary to what you were saying.

And what is wrong with an official confirmation of something you knew was likely to be true anyway? I really don't know what your point is here. Did I know the Z-20 most likely used a domestic engine? Yes. But the Global Times article confirmed this. Find another article predating this one that offers the same level of confirmations. Rumors are good but official sources are even better.

Prototype, the keyword is prototype. Do you not understand what a prototype is?

Let's try this again. Read the following paragraph carefully and answer the question after the paragraph:
The exact type of engine used on the first prototype J-20 (#2001) is unclear (Russian AL-31?). The J-20 #2001 prototype made its first flight at the Chengdu airfield on 11 January, 2011. J-20 has entered service with PLAAF in 2016, a time frame much faster than the one (>2020) anticipated by western military analysts. The latest image (October 2019) suggests that J-20A powered by the indigenous WS-10C turbofan with a serrated (sawtooth) nozzle design is in production. It was rumored that the indigenous WS-15 turbofan engine has been selected for J-20.
Question: what engine does J-20A use?

This is what Huitong said back in February 2014. The exact statement regarding the WZ-10 you highlighted was in Huitong's blog during the early days of prototyping back in 2014. What Huitong was suggesting with this statement was that the Z-20's engine was destined to be the WZ-10, not necessarily its current engine. The statement you highlighted is over 6 years old and yet you use this as confirmation that current production models are powered by the WZ-10. Two can play at this game of using web archives. Only if you're hideous patronizing tone actually worked lol.

Huitong was talking about the "final design" of the Z-20, not its first prototype. In this final design, Z-20 is powered by domestic WZ-10 turboshafts. What is unclear about that?

Moreover, Huitong finally confirmed in 2018 that WZ-10 is indeed equipped on the final product, just as the final design had specified.

Is English your second language?

And here comes the all too predictable @by78 Ad Hominem attack. Please tell me how your quote shows that Huitong confirms the current production versions are using the WZ-10. I have just pointed out the sentence you previously relied on to show this is over 6 years old and doesn't isn't any sort of confirmation.

That was a serious question because you obviously have trouble grasping the basics of English language. So is English your first language?

Anyway, let's try this again. Read the following paragraph carefully, then answer the question after the paragraph:

Since your understanding of basic logic is surprisingly poor, let me ask you a question : have we ever definitively identified the Z-20's engines by outward appearance from a photo? We did with the J-20 and the WS-10 in the prototyping and production stages (as of last year). And for the record, the first batches of production J-20s all had the same engines as the prototypes ... just in case you forgot ;). In the final design of the J-20, it is supposed to be powered by the WS-15. Does it mean that current J-20s should be powered by the WS-15 because they are production types? How do we know definitively that the Z-20 in its current form is its final design?

And applying your logic, where in the Globaltimes article that you linked can I find the photographs by which you have personally "definitively identified the Z-20's engines by outward appearance"?
