The first time I heard an F-22, I couldn’t believe how much louder its engines were than F-18 and F-15 engines. In fact, the only reason I deduced that the aircraft was an F-22 was because I’d never heard a fighter jet so loud before. If there were an advanced method for using acoustic detection for aircraft, the F-22 would be considered anti-stealth.
All about that thrust-to-weight... more thrust = more boom

But before that, weren't there news about WS-15 tested aboard a flanker? Or was that unsubstantiated rumors?
There were rumors in late 2019 that it had already been flown by then, but not yet on the J-20.
Well now a days you don't need to actually fitted on the plane and fly it to test engine for prototype. Isn't there a news that say China built and environmental facility where they can simulate, Elevation, atmosphere condition like rain, wind etc. I guess they probably test the prototype there. And of course the final test has to be on the actual plane, it is intended to use
