Abstract

A combined gas turbine engine vane (122, 222, 322, 422) and blade outer air seal assembly includes a vane (122, 222, 322, 422) having an airfoil (127) extending from a leading edge (124) to a trailing edge (108), and has an outer platform (105). The outer platform (105) has a cooling channel (112) that extends into the airfoil (127) to receive cooling air. The outer platform (105) extends to an integral blade outer air seal to be positioned radially outwardly of a turbine blade (102) in a gas turbine engine (20). At least a portion of the vane (122, 222, 322, 422) and the blade outer air seal are formed of ceramic matrix composite materials.
