A coolable seal assembly, having a ceramic facing material 76, such as an outer air seal 26, for a gas turbine engine is disclosed. The seal assembly is formed of an array of arcuate seal segments 24. Various construction details which enhance the ability of the seal segment to sustain a thermal shock are disclosed. The seal segment is mountable by conventional means in a rotary machine and includes circumferentially extending flanges 30, 32. The longitudinal continuity of the flanges is interrupted to decrease the effect of the flanges on the overall effective thickness and the local effective thickness of the substrate. |
