ABSTRACT:
A unitary structure for use in supplying cooling air to the upstream face of the first stage turbine disk and to the turbine blades on the disk, the structure being a single cast structure having attachment means thereon by which it may be secured to the inner ends of the turbine vanes and also to a part of the combustion chamber such as the inner combustion chamber wall. The structure also provides for attachment of a seal ring to the unitary structure and also includes the turning vanes or nozzles by which the cooling air is directed against the disk, these vanes being cast integrally with the remainder of the structure.
