Low strain shroud for a turbine technical field

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