Abstract

A gas turbine engine (20) is provided that includes compressor, combustor, and turbine sections. The turbine section (28) includes a rotor stage (42) having a bladed rotor (48) and a shroud (50). The bladed rotor (48) includes a disk (54) and a plurality of rotor blades (52) extending radially outward from the disk (54). Each rotor blade (52) has a leading edge (58) and a blade tip surface (66). The shroud (50) is disposed radially outside of the bladed rotor (48), and circumferentially around the bladed rotor (48). The shroud (50) includes a primary segment (PS) (50A) and a forward segment (FS) (50B). The primary segment (50A) has a PS forward end surface (72) and a PS inner radial surface (78). The forward segment (50B) is disposed forward of the rotor blades (52) and is configured to deflect core gas flow away from a blade tip gap (86) disposed between the PS inner radial surface (78) and the blade tip surface (66) of each said rotor blade (52) of the plurality of rotor blades.
