Abstract

A cooling flow arrangement (200) for a ceramic matrix composite (CMC) component (210) of a turbine engine is provided, wherein the CMC component includes a hot side (230) configured for exposure to a hot gas path (232) of the turbine engine and an opposing cold side (240). At least one cavity (220) is provided in the CMC component, the at least one cavity having an entrance disposed on the cold side that is configured for receiving a cooling flow. A seal (260) is disposed adjacent the at least one cavity and the cold side of the CMC component and is configured to provide a seal between the CMC component and an upstream turbine component. At least one hole (262) extends through the seal and is positioned to provide the cooling flow to the at least one cavity of the CMC component.A method (300) of providing a cooling flow to the CMC component (210) includes: providing (310) the at least one cavity in the CMC component ; disposing (320) the seal adjacent the at least one cavity and the cold side of the CMC component to provide a seal between the CMC component and an upstream turbine component; and (330) passing the cooling flow from a source (250) through the at least one hole.
