Abstract: A turbine vane includes an inner platform and an outer platform joined together by an airfoil. The airfoil has a leading edge and a trailing edge joined together by a pressure side and a suction side disposed opposite the pressure side. The inner platform defines a plurality of first inner cooling holes and a plurality of second inner cooling holes that are fluidly connected to an inner cooling passage. The plurality of first inner cooling holes are disposed proximate the leading edge and extend towards the suction side and the plurality of second inner cooling holes are disposed proximate the trailing edge and the suction side and extend towards the leading edge.

Abstract: A baffle insert for a component of a gas turbine engine is provided. The baffle insert having: a first fluid conduit having a first interior cavity extending therethrough; a second fluid conduit having a second interior cavity extending therethrough; and a member located between the first fluid conduit and the second fluid conduit, wherein the member fluidly couples the first interior cavity to an exterior of the second fluid conduit, and wherein the member fluidly couples the second interior cavity to an exterior of the first fluid conduit and wherein the first interior cavity is isolated from the second interior cavity.

Abstract: An airfoil is disclosed, comprising an airfoil body and an internal cavity within the airfoil body. The internal cavity may comprise an outer edge comprising a first outer scallop and a second outer scallop, an inner edge opposite the outer edge, the inner edge comprising a first inner scallop and a second inner scallop, a leading edge spanning between the outer edge and the inner edge, and a trailing edge spanning between the outer edge and the inner edge and opposite the leading edge. Between the outer edge, the inner edge, the leading edge, and the trailing edge, the internal cavity may comprise eight columns of pedestals disposed axially relative to one another and axially between the leading edge and the trailing edge.
