Abstract
Official abstract text for this publication.
A system and a method for controlling an aircraft engine starter/generator. The system includes an AGB of fixed gear ratio for coupling mechanically to a turbine shaft of the engine to enable the engine to be started, a gearbox having multiple gear ratios mechanically coupled to a gearwheel of the AGB, a starter/generator mechanically coupled to a gearwheel of the gearbox, and a controller to cause the gear ratio of the gearbox to be changed as a function of the mode of operation of the starter/generator.
First claim
Opening claim text (preview).
The invention claimed is: 1. A system for controlling a starter/generator of an aircraft engine, the system comprising: an accessory gearbox (AGB) of fixed gear ratio for coupling mechanically to a turbine shaft of the engine, enabling the engine to be started; a starter/generator mechanically coupled to the AGB via a gearbox having multiple gear ratios and interposed between the AGB and the starter/generator; and means for controlling a change in the gear ratio of the gearbox…
