A stator assembly for reducing noise in the outermost portion of the working medium flow path is disclosed. Various construction details are developed which relate to the reduction in noise within the outer twenty percent (20%) of the working medium flow path. In one particular embodiment, an annular channel extends rearwardly from a location between the blades and the vanes for capturing a significant portion of the wake turbulent flow from the tip region of the rotor blades. The annular channel is bounded by a pair of circumferentially extending walls,...
[ What is claimed is:] [1.] A stator assembly for a gas turbine engine having an axis of rotation A.sub.r, a flow path for working medium gases disposed about the axis of rotation, a first outer wall extending circumferentially about the axis of rotation and outwardly bounding the flow path for working medium gases, an array of rotor blades having an axial location, each rotor blade extending radially outwardly across the flow path and having a tip region such that the tip region is in close proximity with the outer wall, an array of stator vanes spaced ...
