Abstract

A gas turbine engine (20) includes a ceramic wall (62) for bounding an engine core gas path (C). The ceramic wall has a ceramic wall first side (64a) that faces the engine core gas path and a ceramic wall second side (64b) that faces away from the engine core gas path. There is a metallic wall (72) adjacent the ceramic wall second side. The metallic wall has a metallic wall first side (72a) that faces the ceramic wall and a metallic wall second side (72b) that faces away from the ceramic wall. The metallic wall and the ceramic wall are spaced apart such that there is a channel (76) there between. There is a seal (78) on the ceramic wall second side, and the metallic wall has at least one cooling hole (80) adjacent the seal for emitting cooling air to cool the seal.
