Abstract

A shroud ring suitable for the turbine of a gas turbine engine comprises an annular heat pipe with radially inwardly directed flanges which are bridged by a plurality of abutting tiles so that together they define an annular chamber. The annular chamber serves to provide a thermal barrier between the tiles and a major portion of the heat pipe. The operating temperature of the shroud ring is thus reduced thereby ensuring reduced radial expansion.
