Failsafe film cooled wall

Failsafe film cooled wall

A flowpath wall (36) is provided for bounding hot combustion gases (18) in a gas turbine engine. The wall includes opposite outer and inner surfaces (38,40) and a plurality of cooling holes (42) extending therebetween. A thermal barrier coating (48) is bonded to the outer surface and covers blind th...
