Abstract
A turbomachine dual spool differential can include a gear assembly configured to combine a low pressure spool input and a high pressure spool input into a combination output to provide an output speed range smaller than a low pressure spool speed range alone. The gear assembly can include a ring gear, a sun gear, and a plurality of planetary gears disposed between the sun gear and the ring gear and meshed with the sun gear and the ring gear. The planetary gears can be rotationally connected to a carrier.
