Abstract: A gas turbine engine may include a deep heat recovery system, such as a deep heat recovery super critical carbon dioxide (sCO2) system. The deep heat recovery system may include two-stage cooling of the working fluid (such as carbon dioxide—CO2) where at least one of cooling stages is recuperative by transferring heat from the working fluid to a flow of compressed air being supplied to a combustor included in the gas turbine engine. The deep heat recovery system may operate in a supercritical cycle, or in a transcritical cycle depending on the temperature to which the working fluid is cooled during a second stage of the two-stage cooling. The second stage of the two-stage cooling includes working fluid-to-air heat rejection where the air is ambient air.

Abstract: A system includes at least one compressor, at least two turbines, and at least two combustors, each fluidically coupled to a respective turbine of the at least two turbines and configured to receive compressed fluid from the at least one compressor. The system further includes at least two motor-generators, each operably coupled to a respective turbine of the at least two turbines and configured to convert electrical energy to mechanical energy to drive a respective propulsor to which the respective motor-generator is operably coupled and to convert mechanical energy from the respective turbine to electrical energy. The system further includes at least two propulsors, each operably coupled to a respective turbine of the at least two turbines and configured to be driven by the respective turbine, a respective motor-generator to which the respective propulsor is operably coupled via the respective turbine, or both the respective turbine and the respective motor-generator.

Abstract: An alternating current type electric propulsion system is described that includes an AC generator and a plurality of propulsors electrically coupled to the AC generator. A first propulsor from the plurality of propulsors includes a first motor that drives a first fan of the first propulsor at a first speed. A second propulsor from the plurality of propulsors comprises a second motor that drives a second fan of the second propulsor at a second speed that is different than the first speed.

Abstract: The disclosure is directed to an optionally hybrid power system that may operate either as a traditional power system, deriving power from a single power source, or as a hybrid power system, deriving power from multiple types of power sources. An example optionally hybrid power system may include a gas turbine engine and one or more electric motors. When configured as a traditional power system the optionally hybrid power system may derive all power from the gas turbine engine. However, when configured as a hybrid power system, the one or more motors may be coupled to the optionally hybrid power system to supplement the power produced by the gas turbine engine. Additionally, an operator interface that may control the optionally hybrid power system may select from a plurality of operating modes that depend on the configuration of the optionally hybrid power system.
