A vane cluster has a platform, a shroud, and at least first and second airfoils extending between an outer face of the platform and an inner face of the shroud. Each airfoil has a pressure side and a suction side. The pressure side of the first airfoil faces the suction side of the second airfoil. The cluster includes a cooling passageway system. The system includes at least one inlet in the shroud. At least one first feed passageway extends from the shroud to the platform through the first airfoil. At least one second feed passageway extends from the shroud to the platform through the second airfoil. A first platform cooling plenum is to the pressure side of the first airfoil. A second platform cooling plenum is to the suction side of the first airfoil.

Vane platform cooling

Provided is an airfoil insert for discharging an increased volume of cooling air. The insert comprises a perforated, tubular-shaped body with a first end for introducing the cooling air. A second end located opposite the first end and discharges an increased volume of the cooling air for use in cooling inboard components. The second end approximates a castellated wall and comprises one or more tabs spaced about the periphery. Alternating between tabs are notches in the body for discharging the cooling air. Covers may be joined to opposing tabs by bridging across the second end, or opposing tabs themselves may be joined together by bridging across the second end.
