Abstract: A turbine system is provided including a plurality of gas turbine engines, each having a compressor section for producing compressed air, a combustor section, and a turbine section yielding hot exhaust gas. A single, common recuperator section is shared by and operatively associated with the plurality of gas turbine engines. A first flow path within the single, common recuperator section is configured to receive compressed air produced by the compressor section of each gas turbine engine. A second flow path, separated from the first flow path and within the single, common recuperator section is configured to receive hot exhaust gases yielded by the turbine section of each gas turbine engine.

Abstract: A filter cleaning system is provided for a gas turbine engine including a compressor section and a combustor section. A mechanism is operatively connected to the gas turbine engine and is configured to be driven by the gas turbine engine in a first mode and configured to drive the gas turbine engine in a second mode. A first flow path is for delivering compressed air to the compressor section. At least one air filter is configured to filter air entering the first flow path. A second flow path is for delivering compressed air from the compressor section to the combustor section in the first mode. A third flow path is for delivering compressed air from the compressor section to the at least one air filter during the second mode.

Abstract: An electric powertrain includes an engine configured to provide mechanical energy and a generator operably coupled to the engine and configured to convert at least a portion of the mechanical energy into electric energy. The electric powertrain further includes at least one electric motor operably coupled to the generator, a plurality of driving members, and at least one power electronics unit configured to control at least one of the engine and the generator. The at least one electric motor is configured to provide torque for the plurality of driving members.
