TURBINE SHROUD SEGMENT WITH SERPENTINE COOLING CHANNELS

摘要

A turbine shroud segment (64) fixed by hooks (72) in the stator of a gas turbine engine includes a serpentine cooling channel (78, 82) along at least one axial edge of the segment. In a particular embodiment, a turbine shroud segment (64) includes a leading edge serpentine cooling channel (78) and a trailing edge serpentine cooling channel (82). Both serpentine channels (78, 82) include ducts (86, 92) that extend to the serpentine channels (78, 82) from a point inward of adjacent retaining hooks (72). Cooling fluid flowing onto the outward surface of the segments flows through the ducts (86, 92) and along the serpentine channels (78, 82) to cool the leading and trailing edges of the segments.
