An inner diameter vane shroud (14) of a variable vane assembly accommodates a synchronization mechanism for coordinating rotation of an array of variable vanes. The inner diameter vane shroud (14) has a gear track (36) that runs circumferentially through the vane shroud (14). An array of variable vanes (26,28) is rotatably mounted in the vane shroud (14) at an inner end. Each vane (26,28) has a gear pinion (38) at its inner end, which interfaces with the gear track (36). As one of the individual variable vanes (26) is rotated by an actuation source (18), the other variable vanes (28) of the variable vane array are rotated a like amount by the rack and pinion gear interface. |
