초록

An electrical machine is embedded into the compressor assembly of a gas turbine engine. An electrical system interface module distributes electrical current to and from the embedded electrical machine for starting the gas turbine engine and for operating accessory components. Accordingly, the gas turbine engine and accessory components can be started and operated without a power-takeoff shaftline and without an external accessory gearbox.

청구항

1. A gas turbine engine having a casing, a shaft rotatably mounted in the casing, and a compressor rotor and a turbine rotor mounted to the shaft within the casing, the engine comprising: a field magnet mounted within an interstage spacer of the compressor rotor, the interstage spacer connecting a first compressor disc blade root region to an adjacent second compressor disc blade root region;a circumferential array of conductive coils mounted in the casing substantially adjacent to a circle defined by revolution of the field magnet within the casing; and...
