Abstract:
A system for moving a thrust reverser, comprising:at least one power source; at least two synchronization mechanisms; and at least two actuators each coupled to at least one of the synchronization mechanisms, at least one of the actuators having: a housing assembly having a first opening, a second opening, a third opening, and a first inside surface defining a first chamber extending along a first axis between the first and second openings, the third opening being located between the first and second openings; a drive shaft rotationally mounted between the openings within the chamber and in general alignment with the first axis, the drive shaft having a gear portion, a lock portion and a first end adapted to couple to at least one of the synchronization mechanisms, the gear and lock portions being located within the chamber; an actuator extending from the third opening of the housing along a second axis that is perpendicular to the first axis, the actuator having a drive gear mounted to engage the gear portion of the drive shaft; and a lock movably mounted within the chamber in an opposite, generally opposed position to the actuator, the lock having at least a side surface and a bottom surface and selectively operable to move in a plane aligned with the second axis between at least a first position and a second position; wherein the lock portion of the drive shaft has at least one protrusion extending radially outwardly, each protrusion having a stop surface positioned to engage the lock side surface when the lock is in the first position to prevent the rotation of the drive shaft.
