Abstract
A hybrid propulsion system for an aircraft includes a gas turbine engine, an energy storage device, at least one propulsor configured to use energy provided by one or both of the gas turbine engine and the energy storage device to provide thrust. The system also includes a controller configured to vary the power provided to the propulsor(s) in response to a signal. The signal may be provided manually by a user of the system or automatically. Automatic signals may be indicative of a threat to the aircraft, geographical location of the aircraft, altitude of the aircraft, or ingestion of particles into the gas turbine engine.
