Maybe in the 2030s. Right now they are still working on the CJ-2000. There are naval gas turbine engines of a similar power level to the GE9X though.

this machine have different names and appearance over the time.. so it is extremely difficult to distinguish between models due to long period of development.. most likely both are the same model.

WS-20 latest improved variant AEP-1300 presented in 2022 Zhuhai air.. pic posted by @Tomboy ..

22 wide chord composite carbon fan blades.


the major reason to go with older clappered fan blades for WS-20 is, it is easy and cheap to mass produce in comparison with wide chord and composite..

WS-20 will produce in large numbers.
