Abstract
A gearbox system includes a gearbox having integrated therein a pump system, a plurality of fluid passages and a clutch control system. The pump system is in fluid communication with the clutch control system via the fluid passages to flow at least one pressurized stream. A first pressurized stream controls a first pressure-responsive device included in the clutch control system. The gearbox system further includes a hydro-mechanical control unit (HMCU) in fluid communication with the gearbox to receive a second pressurized stream and to generate at least one actuator control stream. The actuator control stream controls an actuator integrated in the gearbox.
