Abstract
A variable vane assembly includes a sync ring mechanism for synchronously rotating an array of variable vanes. The variable vane assembly comprises a drive vane, a synch ring, a vane arm and a plurality of follower vanes and follower arms. An inner diameter end of the drive vane rotates in an inner diameter vane shroud. The synch ring rotates in an inner channel of the inner diameter vane shroud. The vane arm connects the inner diameter end of the drive vane with the synch ring. The plurality of follower vanes are connected to the synch ring by the follower arms. When the drive vane is rotated by an actuation source, the plurality of follower vanes rotate a like amount by the synch ring and follower arms.
