摘要： An air turbine starter (10) for starting an engine (14), comprising a housing (30) defining an inlet (32), an outlet (34), and a flow path (36) extending between the inlet (32) and the outlet (34) for communicating a flow of gas there through. A turbine member (38) is journaled within the housing (30) and disposed within the flow path for rotatably extracting mechanical power from the flow of gas. A gear train (40) is drivingly coupled with the turbine member (38), a drive shaft (64, 164, 264) is operably coupled with the gear train (40), and an output shaft (74, 174, 274) is selectively operably coupled to rotate with the engine (10) via a decoupler (72, 172, 272).

摘要： A system for transferring mechanical torque variably between a plurality of rotating machines in a turbofan engine (10). Two devices are used, where the first device relies upon magnetic properties of a planetary magnetic gearbox (50) to couple the magnetic machines. The second device is used to variably control the torque transfer between the magnetic machines. The system couples rotating shafts (52, 54) rotating at differing speeds within a turbofan engine (10) for controllably transferring power. To transfer power in the system, a fixed gear ratio is obtained by coupling the relatively high- and low-speed engine shafts (52, 54) to an epicyclic magnetic gearbox (50).

摘要： A turbomachine (10) comprises a turbine shaft (42), first (36) and second (40) rotors, first (12) and second (14) propulsion stages, and a magnetic stator (38). The first rotor (36) is rotationally coupled to the turbine shaft (42), and coaxially arranged along an axis (C L ). The first propulsion stage (12) is rotationally coupled to the first rotor (36), opposite the turbine shaft (42). The second rotor (40) is coaxially arranged about the first rotor (36), and the second propulsion stage (14) is rotationally coupled to second rotor (40), opposite the turbine shaft (42) and adjacent the first propulsion stage (12). The magnetic stator (38) is coaxially arranged between the first rotor (36) and the second rotor (40), forming a magnetic coupling between the first (36) and second (40) rotors to drive the second propulsion stage (14) in contra-rotation with respect to the first propulsion stage (12).
