Abstract
A propulsion system includes a propulsor, an engine, an electrical assembly, and an emergency energy protection assembly. The engine includes a fuel system. The fuel system includes a fuel control unit. The electrical assembly includes a battery, a motor control unit, an electric motor, and an electrical distribution system. The electrical distribution system includes at least one contactor electrically connected between the battery and the motor control unit. The at least one contactor is switchable between a closed state and an open state. The engine and the electric motor are coupled with the propulsor. The emergency energy protection assembly includes an emergency actuator. The emergency actuator is actuable in an actuated state to control the at least one contactor to switch to the open state, control the motor control unit to deenergize the electric motor, and control the fuel control unit to stop fuel flow for the engine.
