Abstract
An electrical generator for extraction of electrical power from a gas turbine engine includes a rotor portion and a stator portion disposed within a booster cavity of the gas turbine engine. The rotor portion is rotatably supported about the stator portion. The stator portion rigidly is supported within the booster cavity. The rotor portion has a plurality of poles circumferentially arranged opposite the stator portion. The stator portion includes a plurality of coil portions disposed about an outer periphery of the stator portion adjacent to the stator portion. The stator and rotor portions are configured to generate electrical power when the rotor portion is rotated about the stator portion by a shaft of the gas turbine engine to induce electrical currents in the coil portions. The electrical generator extracts electric power from the turbine engine to supplement primary electrical generation sources of the engine.
