Patent ID: 7513101

Claim:
A thrust reverser actuation system, comprising: at least two power drive units each independently operable to supply a drive force; at least two drive mechanisms each coupled to receive the drive force from one of the at least two power drive units; at least two actuators, each actuator coupled to one of the at least two drive mechanisms to receive the drive force from one of the at least two drive mechanisms, each of the at least two actuators having at least one end that rotates in response to the drive force and configured to move, upon receipt of the drive force, between a stowed position and a deployed position; and a synchronization assembly redundantly coupling together the at least two power drive units and configured to transfer power between the at least two drive units to synchronize movement of the at least two actuators, the synchronization assembly comprising a first flexible shaft coupling a first power drive unit to a second power drive unit and a second flexible shaft coupling the first power drive unit to the second power drive unit, wherein each of the first flexible shaft and the second flexible shaft is configured to provide power transfer between the first and second power drive units.
