Abstract:
A variable vane actuation system is disclosed herein. The variable vane actuation system includes a ring member disposed for pivoting movement about a centerline axis. The ring member is engaged with a plurality of vanes in a turbine engine such that the plurality of vanes pivot in response to the pivoting movement of the ring member. The variable vane actuation system also includes a ring moving device engaged with the ring member at first and second positions spaced from one another about the centerline axis. The ring moving device is operable to apply first and second forces, respectively, at the first and second positions to pivot the ring member.
