Abstract
An aircraft system includes a powerplant configured to drive rotation of a propulsor rotor during a first mode and a second mode. The powerplant includes a turbine engine, a first electric machine and a power coupler. A first rotating structure includes a first turbine rotor disposed along a core flowpath. The first electric machine is configured as an electric motor during the second mode. The first electric machine is disposed between the propulsor rotor and the turbine engine. The first electric machine includes a first electric machine rotor coupled to the propulsor rotor. The power coupler is disposed between the first electric machine and the turbine engine. The power coupler is configured to couple the first rotating structure to the first electric machine rotor during the first mode. The power coupler is configured to decouple the first rotating structure from the first electric machine rotor during the second mode.
