Abstract
A blade outer air seal assembly includes a blade outer air seal that has a plurality of segments that extend circumferentially about an axis and mounted in a carrier. At least two of the plurality of segments have a first wall that extends radially outward from a base portion. The base portion has a radially inner side and a radially outer side. A heat shield abuts the radially outer side of the at least two segments. The heat shield is formed from a ceramic material.
