I don’t understand how this works. In a hybrid turbofan electrical power can be used to drive the fan. What does it do here?
iirc it's basically a electric transmission instead of a conventional gearbox for a turboprop.

I think this is intended for eVTOLs. The system would be mounted within a compact nacelle, with the turbine purely serving as a generator. The fan is therefore unneeded both in terms of space consideration and providing direct propulsion.
After watching the latest Fujian carrier catapult tests, I found it strange that the J-35 has already been using the WS-19/WS-21 for carrier catapult launches, which suggests that the naval version of those engines should be fairly mature. So why hasn’t the navalized Taihang come out yet? In the most recent footage, whether it’s the J-15, J-15T, or J-15D, they’re all still running on the AL-31F. Is the WS-10H really that hard to get right? At this point it’s becoming the only Chinese military engine still dependent on foreign supply.
mit does not use WS-19
It has been discussed prior in this thread. Current consensus is the WS-10H(2) will indeed start to be on production J-15Ts soon (could be anywhere from months to years )
The WS-10 series was based on the civilian CFM-56 engine core. Which in turn was based on a bomber engine. The engine takes a long time to spool up. Kind of problematic for a carrier bourne aircraft where crosswinds are a common occurrence and you usually cannot divert to another airstrip.
Surely they have fixed this by now, slow throttle response is detrimental for all fighter design not only naval.
Uhh that was like the initial production version of the engine from like the late 2000s. By the time J-10s were flying with the engines this problem had already been resolved.
