Abstract: The present disclosure provides fluid eductors, systems that utilize fluid eductors, and methods of entraining a suction fluid flow using a fluid eductor. Exemplary fluid eductors include a concentric eductor space or a plurality of annular eductor spaces. Exemplary methods include ejecting a volume of motive fluid out of a concentric eductor space of a fluid eductor, accelerating a peripheral region of the suction fluid flow with the motive fluid ejecting out of the first annular eductor space, and accelerating a core region of the suction fluid flow with the motive fluid ejecting out of the second annular eductor space.

Abstract: A gas turbine engine includes a fan located at a forward portion of the gas turbine engine. A compressor section and a turbine section are arranged in serial flow order. The compressor section and the turbine section together define a core airflow path. A rotary member is rotatable with at least a portion of the compressor section and with at least a portion of the turbine section. An electrical machine is coupled to the rotary member and is located at least partially inward of the core airflow path in a radial direction. An enclosure at least partially encloses the electrical machine. The enclosure at least partially defines a first cooling airflow path within the enclosure that at least partially defines a first cooling airflow buffer cavity at least partially around the electrical machine. The first cooling airflow path is in communication with a second cooling airflow path located outside the enclosure that at least partially defines a second cooling airflow buffer cavity at least partially around the enclosure. A cooling duct provides pressurized air to the first cooling airflow path such that the air flows along both the first cooling airflow path and the second cooling airflow path providing the first cooling airflow buffer cavity and the second cooling airflow buffer cavity.

Abstract: A hybrid-electric propulsion system (150) is provided. In one example aspect, the hybrid-electric propulsion system (150) includes a power converter (188A) and a propulsor (200A). The propulsor (200A) includes a gas turbine engine (210A) having a shaft (246) and one or more bearings (290) supporting the shaft (246). The propulsor (200A) also includes an electric machine (300A) electrically coupled with the power converter (188A). The electric machine (300A) includes a stator assembly (340) and a rotor assembly (310). The rotor assembly (310) has a rotor (312) and a rotor connection assembly (316). The rotor connection assembly (316) operatively couples the rotor (312) with the shaft (246). The rotor connection assembly (316) has an insulated joint (322) for interrupting common mode electric current from flowing from the rotor (312) of the electric machine (300A) to the shaft (246). A grounding device (360) is included to electrically ground the shaft (246). The power converter (188A) includes an electromagnetic interference filter (189A) to reduce common mode voltage reaching the electric machine (300A).
