Patent ID: 7186089

Claim:
A turbine blade, comprising: a generally elongated blade having a leading edge, a trailing edge, and a tip at a first end; a root coupled to the blade at an end generally opposite the first end for supporting the blade and for coupling the blade to a disc; at least one cavity forming a cooling system in the turbine blade; at least one outer wall defining the at least one cavity forming the cooling system; a platform generally orthogonal to the generally elongated blade and proximate to the root; at least one rib protruding from a bottom surface of the platform, extending at an oblique angle to the platform contacting the root; and at least one platform cooling channel in the at least one rib providing a pathway from the at least one cavity forming a cooling system in the root of the turbine blade to an outer side surface of the platform, wherein the at least one platform cooling channel terminates at the outer side surface of the platform to provide impingement cooling to a platform side surface on a platform of an adjacent turbine blade.
