A thrust reverser actuation system is provided that includes a
synchronization system that synchronizes the actuation of at least two
actuators coupled to at least two power drive units. The synchronization
system includes a first synchronization shaft coupling the first power
drive unit to the second power drive unit and a second synchronization
shaft coupling the first power drive unit to the second power drive unit.
The at least two actuators are adapted to receive a drive force and
configured, in response to receipt of the drive force, to move between a
stowed position and a deployed position. The synchronization system is
configured to transfer power between the first power drive unit and the
second power drive unit, thereby eliminating a mismatch in power and
provide uniform deployment of the at least two actuators.
