Examples described herein provide a computer-implemented method that includes providing the hybrid electric engine, the hybrid electric engine having a gas generating core and an electric machine powered by electric energy. The method further includes determining, by a processing device, whether a use of the electric energy will increase time on wing of the hybrid electric engine of the aircraft a threshold amount. The method further includes, responsive to determining that the use of energy will increase time on wing the threshold amount, apportioning the electric energy from a battery system of the aircraft to increase the time on wing.

Energy optimization for a hybrid electric engine

A compressor section for a gas turbine engine includes an upstream portion that includes at least one upstream rotor stage. A downstream portion includes at least one downstream rotor stage configured to rotate with the upstream rotor stage. A transition duct separates the upstream portion from the downstream portion.

Transition duct for a gas turbine engine

A load shedding system for operating at least one circuit breaker positioned within an enclosure is described. The load shedding system includes a processor configured to receive a demand signal and to provide a predetermined load shedding signal. The load shedding system also includes at least one load shedding apparatus configured to receive the load shedding signal from the processor. The load shedding apparatus is configured to be coupled to a door of the enclosure. The load shedding apparatus is further configured to be operatively coupled to the at least one circuit breaker and further configured to actuate the at least one circuit breaker in response to the load shedding signal.
