    摘要: A system is described that includes a turbine engine including an engine fan including one or more variable-pitch blades driven by a shaft, which rotates at a rotational speed which depends on a pitch of the one or more variable-pitch blades of the engine fan. The system further includes a generator configured to produce alternating-current (AC) electricity at a particular frequency relative to the rotational speed of the shaft. The system also includes a propulsor, which includes a propulsor motor and a propulsor fan. The propulsor motor is configured to drive, based on the AC electricity produced by the generator, the propulsor fan. The system includes a controller configured to control the particular frequency of the AC electricity by at least controlling the pitch of the one or more variable-pitch blades of the engine fan and thereby the rotational speed of the generator.

    摘要: An electrical generator for extraction of electrical power from a gas turbine engine (10) includes a rotor portion (22) and a stator portion (24) disposed within a booster cavity (14) of the gas turbine engine (10). The rotor portion (22) is rotatably supported about the stator portion (24). The stator portion (24) rigidly is supported within the booster cavity (14). The rotor portion (22) has a plurality of poles circumferentially arranged opposite the stator portion (24). The stator portion (24) includes a plurality of coil portions (28) disposed about an outer periphery of the stator portion (24) adjacent to the stator portion (24). The stator (24) and rotor portions (22) are configured to generate electrical power when the rotor portion (22) is rotated about the stator portion (24) by a shaft of the gas turbine engine (10) to induce electrical currents in the coil portions (28). The electrical generator extracts electric power from the turbine engine to supplement primary electrical generation sources of the engine (10).

    摘要: An electrical power generation system (100) for an aircraft gas turbine engine (10). The system comprises an alternating current electrical generator (110) having a rotor (114) comprising a plurality of electromagnetic rotor windings (118) and a stator (124) comprising a plurality of electrical stator windings (126). The rotor (114) is mechanically coupled to a shaft (36) of the gas turbine engine (10) by a transmission system (129). The electrical generator (110) further includes an electrical output frequency controller (130), a torque sensor arrangement configured to determine a torque imposed on the transmission system (129) by the generator (110) and a controller (112) configured to operate the electrical power generation system in first mode and second modes. In the first mode, the frequency of the electrical power output of the electrical generator (110) is controlled by the electrical output frequency controller (130) to lie within predetermined limits, and a reduced idle signal is provided to a gas turbine engine controller (132). In the second mode, the frequency of the electrical power output of the electrical generator (132) is not controlled by the electrical output frequency controller (130) and an increased idle signal is provided to the gas turbine engine controller (132). The electrical generator controller (112) is configured to operate the electrical power generation system (100) in the first mode when the torque is below a predetermined limit, and in the second mode when the torque is above a predetermined limit.
