Stator assembly for a gas turbine engine

摘要

A coolable stator assembly is positioned outwardly of an array of rotor blades in a high by pass turbofan gas turbine engine as disclosed. The stator assembly includes case tied air seals positioned by rails and a shield which extends circumferentially about the rails and the rail connector section extending between the rails. Various constructions details for improving the control of clearances and circumferential temperature gradients in the rails are developed. In one particular embodiment, cooling air tubes are employed with the shield.
