ABSTRACT:
An inner diameter vane shroud of a variable vane assembly accommodates a synchronization mechanism for coordinating rotation of an array of variable vanes. The inner diameter vane shroud has a gear track that runs circumferentially through the vane shroud. An array of variable vanes is rotatably mounted in the vane shroud at an inner end. Each vane has a gear pinion at its inner end, which interfaces with the gear track. As one of the individual variable vanes is rotated by an actuation source, the other variable vanes of the variable vane array are rotated a like amount by the rack and pinion gear interface.
