초록

The invention is directed to a multi-motor actuation system for a power drive unit. The system includes three independently hydraulically controlled motors adapted to be drivingly coupled to a power drive unit output. Two of the said motors are normally active at all times and the third motor acts as a back-up motor to provide redundancy for the two normally active motors. A hydraulic failure detection mechanism is controllingly coupled to the three independently hydraulically controlled motors. The hydraulic failure detection mechanism is responsive to ...
