Abstract

A turbine engine power generation system includes a gearbox that receives rotational drive from a low spool through an input gear, in one example. The gearbox includes first and second clutches that are coupled to an input shaft of an auxiliary component, such as a generator. First and second output gears are driven at different rotational speeds by the input gear and respectively associated with the first and second clutches. An actuator selectively engages at least one of the first and second clutches to select between first and second rotational speeds in response to a command from a controller.
