Abstract: Systems and methods include providing a stator vane bushing for a variable stator vane assembly having a movable stator vane and a stator vane housing disposed annularly about the movable stator vane. The bushing includes a flange, a barrel extending from the flange, and a central aperture extending through the flange and the barrel and is disposed in the housing and annularly about the stator vane. The bushing is formed from a ceramic material having a coefficient of thermal expansion (CTE) lower than or equal to a CTE of one or more of a stator vane and a housing of the variable stator vane assembly.
