If a CFM56 or any bypass engine for that matter, is operated in icing conditions without the engine anti-ice selected on, in flight, at idle/low speeds, when the ice lets go does it all get flung out centrifugally and go out the bypass duct? How much if any goes through the core?

How about at higher thrust settings?

Thanks - Regards - musang

On the A346/Trent 500 combination there is an ECAM warning 'ENG STATOR ICEING RISK' if the engine has been operating in iceing conditions at low power for 10 minutes. From a maintenace POV if this appears in the log book we have to boroscope the engine before next flight

Almost all fan ice shedding gets centrifuged out through bypass. The FGV ice also obviously goes through bypass. The IGV ice goes through the core and the splitter lip ice can go either way depending on the thrust level and thus the core streamtube capture area.
