Abstract
A blade outer air seal (BOAS) segment of a gas turbine engine includes a support component extending circumferentially in an arc and an arcuate ceramic matrix composite (CMC) sleeve that slides onto the support component. The support component may be made of metal such as a high Nickel (Ni) content alloy or a high Cobalt (Co) content alloy and includes a pair of rails. The CMC sleeve can be formed of a plurality of stacked plies to have a uniform thickness, and include arcuate upstream and downstream curves to engage the pair of rails. The CMC sleeve can be uniformly densified and maintain a uniform thermal gradient. A flexible insulation blanket formed of carbon/graphite felt may be disposed between the rails of the support component and the CMC sleeve to avoid the need to cool the support component.
