Stator vane support assembly

摘要

A stage of circumferentially disposed turbine stator vane clusters and arcuate, circumferentially disposed segments of a rotor outer air seal disposed on one side of the stator stage is secured to an annular attachment ring which is integral with a surrounding turbine case. The outer seal segments are trapped axially between stator vane clusters and the radially inner ends of arcuate support segments, and are also radially supported thereby. The radially inner ends of the support segments are trapped axially between the stator vane clusters and the annular attachment ring, and are also supported radially thereby. This boltless attachment reduces the number of parts while providing strong radially support and accurate radial location for the seal segments.
