Abstract
A gearbox assembly for a turbine engine. The turbine engine includes an engine static structure. The gearbox assembly includes a gear assembly, an input shaft coupled to the gear assembly, an output shaft drivingly coupled to the input shaft through the gear assembly, and a gearbox assembly disengagement system. The gearbox assembly disengagement system includes a one-way clutch that engages the gearbox assembly to the engine static structure during a normal operation of the turbine engine and disengages the gearbox assembly from the engine static structure during a reverse torque condition.
