ABSTRACT:
A stator vane stage in a split-case, variable geometry axial flow compressor includes two 180-degree spoke-like arrays of stator vanes on upper and lower case halves of the compressor case and a pair of unitary, 180-degree arc shroud ring segments. Each stator vane has a pivot shaft at one end rotatably supported in a radial bore in the corresponding case half by a bushing and a cylindrical vane button at the other end. Each shroud ring segment has a corresponding plurality of cylindrical vane button sockets in an outer surface thereof which rotatably receives a corresponding vane button. The spoke-like array of the stator vanes rigidly positions the shroud ring segments relative to the compressor case. To assemble the shroud ring segments to the stator vanes, the shroud ring segments are first resiliently squeezed radially inward while the vane buttons are sequentially inserted into the corresponding vane button sockets and then released to spring back to their true 180-degree arc shapes in which they are captured on the stator vanes.
