ABSTRACT:
A turbine shroud assembly includes an expansion control ring to support segmented rotor shrouds. The expansion control ring is restrained by adjacent manifold rings, yet free to thermally expand radially outwardly without loss of axial alignment with the associated turbine wheel. The ported manifold rings are positioned on either side of an outwardly extending leg of the expansion control ring to direct cooling fluid delivered thereto toward the expansion control ring. A spacer ring surrounds the expansion control ring and restrains the expansion control ring relative to the manifold rings. The spacer ring maintains axial alignment of the expansion control ring with the turbine wheel. Cooling fluid is exhausted into the main hot gas stream, both upstream and downstream of the turbine wheel thus substantially preventing hot gases from affecting the expansion control ring.
