    Abstract: An engine system includes a gas generator section and a load compressor. The gas generator section includes a core compressor, a combustion assembly, and a turbine. The core compressor receives and compresses a first flow of air as first compressed air. The combustion assembly receives the first compressed air from the compressor, mixes the first compressed air with fuel, and combusts the first compressed air and fuel mixture to result in combustion gases. The turbine receives the combustion gases from the combustion assembly and extracts energy from the combustion gases. The load compressor is driven by the turbine, and it is further configured to receive and compress a second flow of air as second compressed air. At least a portion of the second compressed air is directed to the gas generator section as cooling air.

    Abstract: An electromechanically controlled aircraft power transmission system includes a first planetary gear set, a first gas turbine engine, a first electric machine, a second planetary gear set, a second gas turbine engine, a second electric machine, a propulsor shaft, and at least one propulsor. The first gas turbine engine is coupled to the first planetary gear set. The first electric machine is coupled to the first planetary gear set and is configured vary the gear ratio of the first planetary gear set. The second gas turbine engine is coupled to the second planetary gear set. The second electric machine is coupled to the second planetary gear set and is configured to vary the gear ratio of the second planetary gear set. The propulsor shaft is coupled to the first and second planetary gear sets and the at least one propulsor is coupled to the propulsor shaft.
