Claim:
1. A turbine engine, comprising: at least one combustor positioned upstream from a rotor assembly, wherein the rotor assembly includes at least first and second rows of turbine blades extending radially outward from a rotor; a compressor positioned upstream from the at least one combustor; at least one row of turbine vanes extending radially inward and terminating proximate to the rotor assembly; an inner case extending from a downstream end region of the compressor to an upstream end region of the rotor assembly; a heat shield wall positioned radially outward of the inner case and circumferentially encapsulating the inner case, thereby forming a heat shield manifold on an outer surface of the inner case; a turbine airfoil cooling chamber in communication with turbine airfoils, wherein the turbine airfoil cooling chamber extends downstream of an end of the inner case and an end of the heat shield wall; a support extending radially outward from the inner case and supporting the heat shield wall; and a compressor bleed exhaust in communication with the heat shield wall whereby the compressor bleed exhaust supplies cooling fluid to the heat shield manifold and is in communication with a turbine airfoil cooling chamber such that the heat shield manifold supplies cooling fluid to the turbine airfoil cooling chamber.
