Abstract
An integrated drive generator system in which all of the main components of the system are mounted for operation about a single centerline. A housing mounts a drive input shaft. A differential is coupled to and arranged coaxially of the drive input shaft. A generator is coupled to the differential and includes a rotor coaxially of the drive input shaft. A hydraulic log includes a hydraulic pump and motor assembly coupled to the differential and arranged coaxially of the drive input shaft. An exciter also is employed coaxially of the drive input shaft, surrounding the differential, and a compact cooling system includes cooling passages integral with the housing and in close proximity to the stator of the generator.
