I'm curious, which model is the turboshaft engine with a power-to-weight ratio of 9 that is the same generation as the push ratio 10 turbofan engine.

WS-15 first flew in summer 2021 with single machine.

then again in late half of 2021 with twin engines.

CCTV/Globaltimes confirmed too.

and official confirmation came in late 2022. almost 18 months later. it means WS-15 passed critical initial test and Chinese are fully satisfied with the performance.

That's indeed highly likely, we know the first image showing allegedly the WS-10-powered prototype since June 2021 and that fits nicely. AFAIR this was the first post mentioning an alleged maiden flight of the WS-15-powered J-20.

But AFAIR correctly, we have no image yet showing it with two WS-15s?

Liu said, "The third generation of military aircraft engines are basically self-sufficient, and now there is no need to buy a lot of engines from Russia."

In the seminar, Professor Liu Daxiang actually announced three important milsetone achivements regarding China's aviation engines, two of which have been stated here:

1. Chinese (3rd generation) low-bypass turbofan engine procurement has practially achieved self-sufficiency, hence no longer demanding much reliance on imported engines from Russia than ever before; and
2. WS-15, i.e. China's leading 4th-generation low-bypass turbofan engine with thrust-to-weight ratio (TWR) of above 10 has made its maiden flight, albeit not yet fielded on active service J-20s.

Then there is the following:

3a. Next generation (i.e. 5th-generation) low-bypass turbofan engine for use on fighters and bombers with TWR of 12-15;
3b. Next generation turboshaft engine for use on helicopters with power-to-weight ratio (PWR) of 11-12; and
3c. Turbine-based combined cycle engine/Turboramjet engine (TBCC) -
Have achieved key technological breakthroughs in their respective research and development progresses.

Speaking of 5th-generation turbofan engine (12-15 T/W ratio) for fighters AND bombers, could that be referring to China's 6th-generation fighter and the H-20?
