Abstract

A brush seal (200) for use with a ceramic matrix composite (CMC) component (210) of a gas turbine engine may feed a cooling flow to the CMC component, which has a hot side (212) configured for exposure to a hot gas path of the gas turbine engine and an opposing cold side (214) having a cavity (216) for feeding a cooling flow to at least one film cooling hole (218) of the CMC component. The brush seal includes: an outer diameter (OD) backing plate (220); an inner diameter (ID) backing plate (230); a plurality of brush seal bristles (240) sandwiched between the OD backing plate and the ID backing plate; at least one hole (250) forming a passage extending through the OD backing plate, the brush seal bristles, and the ID backing plate; and a cover plate (260) attached to an inner surface of the ID backing plate and configured to extend into the cavity of the CMC component.
