Method for aircraft engine start using synchronous generator and constant speed drive

摘要

A method of starting an aircraft engine (17) is provided. The method includes providing motive power from a generator (14) for starting an engine (17) during an engine start mode and deriving electrical power by way of the generator (14) from rotation of the engine (17) during a generate mode, transmitting the motive power from the generator (14) to the engine (17) during the engine start mode by way of a constant speed drive (CSD) (15) and regulating a frequency of the electrical power output from the generator (14) during the generate mode by way of the CSD (15) and coupling a generator and CSD controller (GCC) (16) to the generator (14) and the CSD (15) and operating the generator (14) and the CSD (15) by the GCC (16) to execute at least the engine start mode and the generate mode.
