摘要： A starter-generator system is configured to supply power to an aircraft electrical bus having a rated AC voltage magnitude, or receive power from a start converter, and includes a rotor and a stator. The stator is disposed at least partially around at least a portion of the rotor and has at least one multi-phase stator winding set wound thereon that has an increased number of turns per phase that is greater than a least number of turns per phase needed to supply power to an aircraft electrical bus at the rated AC voltage magnitude. The increased number of stator turns results in reduced current drawn by the starter-generator during the motor mode, which improves the efficiency and introduces other benefits to the overall starting system.

摘要： An apparatus (80) controls a synchronous machine (20) used to start an engine (300) during an engine start operation. The apparatus comprises: an exciter current control unit (84) for controlling exciter current output to the synchronous machine (20) during the engine start operation; and a main current control unit (82) for controlling main current output to the synchronous machine (20) during the engine start operation as a function of machine speed. In one implementation, the main current control unit (82) controls main current output to the synchronous machine (20) so that the synchronous machine (20) exhibits a reduced output torque during an initial torque application stage. The reduced viscous drag effects and reduced impact torque are beneficial to the engine system (100).

摘要： A method and apparatus for executing a no-break power transfer between an electrical power generator powered by an auxiliary power unit (APU) and an electrical power generator powered by an aircraft main engine. The method comprises sending a power transfer command, a load/unload amplitude signal, and a target frequency signal from a bus power control unit to an APU electronic control unit; deriving a calculated load range for the APU at a new load and frequency operating point; and determining if the new load and frequency operating point falls within the calculated APU load range. If within range, a no-break power transfer is initiated; if not within range, a power transfer with momentary interruption is initiated.

摘要： Two spool gas turbine engines are often used to drive variable speed loads, such as an electric generator, or the fan/propeller of aircraft engines. The gas turbine engine must be designed to withstand transient speed and temperature conditions which are encountered when sudden changes to the load on the generator, fan, or propeller occur. By adding a relatively small motor/generator to the gas generator spool of the gas turbine engine, the compressor speed and airflow can be quickly adjusted to compensate for external load changes. This reduces the severity and duration of the transient conditions, resulting in decreased operation and reliability problems such as overspeed, compressor surge, and high turbine temperature. The motor/generator may also be used as an engine starting device.
摘要翻译：两个阀芯燃气涡轮发动机通常用于驱动变速负载，例如发电机或飞机发动机的风扇/螺旋桨。燃气涡轮发动机必须设计成可以承受当发生器，风扇或螺旋桨上的负载发生突然变化时遇到的瞬态速度和温度条件。通过向燃气涡轮发动机的气体发生器阀芯添加相对较小的电动机/发电机，可以快速调节压缩机速度和气流以补偿外部负载变化。这降低了瞬态条件的严重性和持续时间，从而导致操作和可靠性问题的降低，如超速，压缩机浪涌和高涡轮机温度。马达/发电机也可以用作发动机起动装置。
