Aren't both the H-6 and Y-20 using D30 engines in the first place, before being substituted by WS-18? At least that's limited to what I came across.
2021, Zhuhai air show, Y-20 chief designer said.
Y-20 has already Chinese heart and in-fact we are testing two different types of Turbofan on Y-20 aircraft. process is smooth..
its obvious, he is talking about WS-18 and WS-20 ..
I remember this report but exactly the part „we are testing two different types“ leave the uncertainty on if they are still testing or if current production aircraft are already equipped with the WS-18?
unfortunately nobody knows. i think WS-20 approaching ''enter in service'' status. so we might never get any information regarding WS-18 equipped with Y-20 entered in production..
As per Yankeesama YY-20 already use WS-18. It is pretty much indistinguishable externally from D-30 though.
There are also Y-20s with “Ship of Theseus” style domestic engines. They started off being imported D-30s but gradually had all their parts replaced during maintenance.
that's good to hear. means Y-20 rolling off from the production line are powered by WS-18 engines..
But I suppose that the Y-20s that are rolling off the production lines right now are powered by WS-20 instead of WS-18?
WS-20 about to enter in service.. so far mostly are with WS-18.. but you can say this. we have seen many units equipped with WS-20 engines too.
