摘要： A hybrid power system for an aircraft. The hybrid power system comprises a high-voltage DC (HVDC) bus and a generator-motor system configured to (1) selectively receive electric power from the HVDC bus to assist in providing propulsion and (2) provide electric power to the HVDC bus during regulated power extraction. An LPS generator/motor is coupled with an LPS shaft of an engine. An HPS generator/motor is coupled with an HPS shaft of the engine. A first AC/DC converter is connected to the LPS generator/motor and the HVDC bus. A second AC/DC converter is connected to the HPS generator/motor, the first AC/DC converter, and the HVDC bus. An electric motor is connected to the HVDC bus and configured to provide propulsion and/or electric power. Further, AC and DC distribution systems are connected to the HVDC bus. A control system is configured to selectively control connections to the HVDC bus.

摘要： One example provides a method for generating and using electric power in a hybrid power system for an aircraft. The hybrid power system has an engine and a high-voltage DC (HVDC) bus interconnecting a generator-motor system, an AC distribution system, and a DC distribution system. The method comprises operating the engine through a plurality of different operation phases. The method further comprises selectively providing, based on thrust demands of the engine, electric power from the HVDC bus to the generator-motor system to assist the engine in providing thrust. The method further comprises selectively extracting, using the engine driving the generator-motor system with a high-pressure spool (HPS) shaft and/or a low-pressure spool (LPS) shaft of the engine, electric power from the engine. The method further comprises selectively delivering the electric power extracted from the engine to the AC distribution system and/or the DC distribution system.
