A compressor stator vane assemblage includes a first metal bushing disposed within a bore through the compressor casing and bolted to the casing by externally accessible bolts. A second composite bushing is disposed within the first bushing and receives the spindle of the stator vane. Reduced diameter portions of the spindle project through openings in the first and second bushings. A lever attaches to the spindle portion and is movable to rotate the vane. By removing the bolts, the first and second bushings can be removed from the casing for replacement or rotation of 180.degree. for prolonged service life without disassembly of the casing or removal of the stator vane.

Variable stator vane mounting and vane actuation system for an axial

A variable angle stator vane assembly for an axial flow gas turbine engine compressor. The compressor casing has a bore surrounded by a boss at the position of each assembly. A housing having a central bore and a bushing assembly is located in the casing bore and is bolted to the boss. The stator vane spindle extends through the housing bore and busing assembly. The housing and bushing assembly can be removed from the casing bore, to be rotated 180.degree. or replaced, without removing the casing from the compressor or the stator vane spindle from the casing bore.
