ABSTRACT:
Variable stator vane arrangements for compressors of gas turbine engines suffer from errors in the angular position of the variable stator vanes because of relative movement between the stator casing and control ring which is allowed by a clearance between the stator casing and control ring. A plurality of pieces of material which have a relatively high coefficient of expansion are arranged circumferentially and are positioned radially between the control ring and the stator casing. The pieces of material control the effective clearance between the control ring and the stator casing so that the error of the variable stator vane angular position is minimized. The pieces of material may be formed from a polyimide resin or high coefficient of expansion steel, and may be positioned in housings which are secured to the control ring.
