Abstract:
A pivot ring arrangement for a stage of variable stator vanes (VSVs) (38) in a gas turbine engine comprises a plurality of segments (12) secured in a segment carrier (22). The segments are injection molded from self-lubricating material, obviating the need for separate bushes for the VSV spindles (36).
