Abstract
The flow path shroud includes a plurality of generally channel-shaped shroud segments having forward and rearward rails interconnected by a flow path section along radial innermost portions of the rails. The volume bounded by the forward and rear rails and flow path sections is unbounded at the ends and the shroud therefore is without side walls. The free ends of the front and rear rails have relief cuts such that thermal induced bowing of the front and rear rails in the axial direction limits the mechanical stress applied to the turbine casing hooks. The thickness of the front and rear walls lies in an approximately 1:1 thickness ratio with the thickness of the flow path section.
