Abstract
A vane assembly includes a vane having an outer platform with mount structure and an airfoil extending inwardly from the mount structure and formed of ceramic matrix composites ('CMC'). The vane has an internal cooling chamber. A metal baffle is received within the internal cooling chamber and extends beyond the platform. A bathtub seal has a central portion receiving the metal baffle. The metal baffle has a central chamber and cooling air holes to deliver cooling air into the internal cooling chamber. The bathtub seal has an inner wall and an outer wall outward of the metal baffle. The inner wall, the outer wall and a bottom wall define a bathtub seal chamber. The bottom wall is in contact with an upper surface of the vane. The vane is connected to the outer wall. Static structure is received within the bathtub seal chamber. A gas turbine engine is also disclosed.
