Abstract: A control for a hybrid turbo electric aero-propulsion system prioritizes and optimizes the operating parameters, according to a desired optimization objective, for and across a number of different control optimization subsystems of the hybrid turbo electric aero-propulsion system. The control subsystems may include, for example, a propulsion control optimization subsystem and a power plant control optimization subsystem. The optimizations may be based on a system model, which is developed and updated during the operation of the hybrid turbo electric aero-propulsion system.

Abstract: A magnetic gearbox for use in a gas turbine engine includes an inner rotor assembly, a stator assembly, and an outer rotor assembly. The inner rotor assembly includes a first plurality of permanent magnets and an inner rotor. The outer rotor assembly includes an outer rotor and a second plurality of permanent magnets. Each of the inner and outer rotors include a plurality of slots to receive an attachment portion of each of the first and second plurality of permanent magnets to secure the plurality of magnets relative to the rotors during rotation.

Abstract: A sensor communication system includes an electromagnetic waveguide disposed adjacent to at least one component of a machine. The electromagnetic waveguide can be configured to convey a fluid within the machine. The sensor communication system can also include a sensor assembly, which includes a sensor operable to sense at least one condition and a transmitter at least partially positioned in the electromagnetic waveguide. The transmitter can be operatively coupled to the sensor and be operable to emit a signal corresponding to the at least one condition sensed by the sensor. The sensor communication system can also include a receiver at least partially positioned in the electromagnetic waveguide and operable to wirelessly receive the signal emitted by the transmitter.
