TURBINE SHROUD SEGMENT FEATHER SEAL LOCATED IN RADIAL SHROUD LEGS

摘要

A gas turbine shroud assembly (32) comprising a plurality of shroud segments (42), each segment including a platform (44) and radially extending front and rear legs (46, 48) integrated with the platform, and pairs of seals (74) provided between adjacent shroud segments. The legs are provided with slots (72) into which the seals are inserted. The seals are disposed between the radial legs of adjacent shroud segments leaving gaps between adjacent platforms through which shroud cooling air escapes radially into the main gas path, thereby cooling the sides (58, 60) of the platforms of the respective shroud segments.
