    摘要: A synchronous electric machine operates as a starter-generator for an aircraft. When operating in a starting mode, a main stator of the machine is supplied with electrical power at a constant frequency. An exciter stator is supplied with variable frequency power. As rotational speed increases, the exciter variable frequency changes correspondingly to maintain synchronous operation of the machine and maximum torque. In a generator mode, variable frequency is applied to the exciter stator with the exciter frequency varying as a function of rotational speed of an engine driving the machine. This provides for a constant frequency output from the machine.

    摘要: Systems and methods for providing AC power from multiple turbine engine spools are disclosed. A system in a particular embodiment includes a turbofan engine having a compressor, a first turbine and a first shaft connected between the compressor and the first turbine, and a fan, a second turbine and a second shaft connected between the fan and the second turbine. The system can further include a state power bus and a first energy converter coupled between the first shaft and the power bus, with the first energy converter including a starter/generator, and being positioned to convert a first variable frequency energy transmitted by the first shaft to a first generally constant frequency energy. A second energy converter can be coupled between the second shaft and the power bus, with the second energy converter including a generator and being positioned to convert a second variable frequency energy transmitted by the second shaft to a second generally constant frequency energy, with the second generally constant frequency energy in phase with and at generally the same frequency as the first generally constant frequency energy. A controller can be operatively coupled to the starter/generator and the generator, e.g., to control the functions of these devices.

    摘要: A power transmission arrangement comprises a first power transmission member connectable to a first main shaft of an engine. The arrangement also includes a second power transmission member connectable to a second main shaft of the engine and to a third power transmission member. A coupling assembly is provided which has a selectable coupling condition to couple the first power transmission member to the second power transmission member to allow power to be transmitted from the third power transmission member to the first main shaft of the engine via the first power transmission member. The coupling assembly has a decoupling condition to decouple the first power transmission member from the second power transmission member to allow power to be transmitted from the main shaft of the engine to the third power transmission member via the second power transmission member.
