Abstract
A hybrid electric aircraft propulsion system includes both a turbine engine and an electric motor. A power management system controls operation of the electric motor and a pitch angle of a propeller associated with the propulsion system. A disconnect switch is provided to isolate the electric motor by mechanical decoupling the electric motor from the aircraft propulsion system.
