Abstract
A drive system includes a planetary gear system. An input is affixed to a sun gear of the planetary gear system to rotate therewith and an output is affixed to the output ring gear to rotate therewith. A first brake system is selectively operable to rotationally lock an output ring gear of the planetary gear system, and a second brake system is selectively operable to rotationally lock the planet carrier of the planetary gear system. Rotary-wing aircraft implementations of the drive system are also disclosed.
