Abstract
An assembly is provided for an aircraft. This aircraft assembly includes a first propulsor rotor, a geartrain, a rotating assembly and an auxiliary turbine. The rotating assembly is rotatable about an axis and includes a turbine rotor. The rotating assembly is coupled to and is configured to drive rotation of the first propulsor rotor through the geartrain. The auxiliary turbine is coupled to the first propulsor rotor independent of the geartrain.

2 more elements
An assembly for an aircraft, comprising:
- a propulsor rotor;
- a geartrain;
- an engine core including a compressor section, a combustor section, a turbine section, a flowpath and a rotating assembly, the flowpath extending longitudinally through the compressor section, the combustor section and the turbine section from an inlet into the flowpath to an exhaust from the flowpath, the rotating assembly comprising a turbine rotor arranged within the turbine section, and the rotating assembly configured to drive rotation of the propulsor rotor through the geartrain;
- an auxiliary turbine configured to further drive the rotation of the propulsor rotor;
- and
- a clutch configured to couple the auxiliary turbine to the propulsor rotor when the auxiliary turbine is operational, and the clutch configured to decouple the auxiliary turbine from the propulsor rotor when the auxiliary turbine is non-operational.
