Abstract

A vane assembly includes a vane (302) having an internal cavity (312, 314), a vane platform (318) and a vane rail (316) defining, in part, an outer diameter supply cavity (320). A blade outer air seal support (306) is arranged adjacent the vane and engages with a portion of the vane, the BOAS support having a BOAS support rail (326), and a BOAS (304) supported on the BOAS support and engaging with a portion of the vane. The BOAS support includes a first cooling flow aperture (328) configured to enable a cooling flow to cool at least the BOAS and a second cooling flow aperture (338) formed in the BOAS support rail. The vane rail includes a third cooling flow aperture (340) to form a cooling flow path through the second cooling flow aperture and the third cooling flow aperture to fluidly connect to the outer diameter supply cavity.
