Abstract:
1. An electrical generator for extraction of electrical power from a gas turbine engine comprising: a rotor portion and a stator portion disposed within a booster cavity of the gas turbine engine, the gas turbine engine comprising a first shaft driving a low pressure turbine and a second shaft driving a high pressure turbine, the first and second shafts independently rotatable, the rotor portion rotatably positioned on an outer perimeter of the stator portion and supported about the stator portion, and the stator portion rigidly supported within the booster cavity; the rotor portion having a plurality of poles circumferentially arranged opposite the stator portion; the stator portion having a plurality of coil portions disposed about an outer periphery of the stator portion adjacent to the rotor portion; the stator and rotor portions being configured to generate electrical power when the rotor portion is rotated about the stator portion by the first shaft of the gas turbine engine to induce electrical currents in the coil portions.
