Abstract
An aircraft propulsion system assembly includes an aircraft propulsion system and a control assembly. The aircraft propulsion system includes a propulsor, an engine, and an electric motor. The engine includes a rotational assembly coupled to the propulsor. The electric motor includes a rotor coupled to the propulsor. The control assembly includes a propulsion system sensor assembly, a plurality of channel A control units, and at least one channel B control unit. The propulsion system sensor assembly is configured to measure one or both of a rotation speed and a torque of the propulsor. The plurality of channel A control units includes an engine control unit and an electric motor control unit. The channel B control unit is configured to identify valid and invalid output control signals of the engine control unit and the electric motor control unit using the one or both of the rotation speed and the torque.
