    摘要： An aircraft system is provided that includes a thrust rotor (22) and a powerplant (24) coupled to and configured to drive rotation of the thrust rotor (22). The powerplant (24) includes a gas turbine engine, a drivetrain (30) and a fluid motor (28). The gas turbine engine includes a rotating assembly (70), a compressor section (44), a combustor section (45), a turbine section (46) and a flowpath (42) extending through the compressor section (44), the combustor section (45) and the turbine section (46). The rotating assembly (70) includes a turbine rotor (58) in the turbine section (46). The turbine rotor (58) is configured to convert fluid power of combustion products flowing through the flowpath (42) within the turbine section (46) into mechanical power for driving rotation of the rotating assembly (70) during a mode of engine operation. The drivetrain (30) is configured to rotatably couple the fluid motor (28) to the rotating assembly (70). The fluid motor (28) is configured to boost the mechanical power for driving the rotation of the rotating assembly (70) during the mode of engine operation.
