Integrated drive generator having a variable input speed and constant output frequency and method of driving

摘要

An integrated drive generator, 10, having a variable input speed and constant output frequency, where the integrated drive generator includes a generator, 14, disposed about a first centerline, Also included is a hydraulic trimming device, 16, disposed about a second centerline, Further included is an epicyclic differential, 18, having a ring gear, 30, and a sun gear, 38, wherein at least one of the ring gear and the sun gear drives the generator at a constant output frequency, wherein the epicyclic differential is disposed about a third centerline, wherein the third centerline corresponds to the second centerline.
