<p>A platform cooling arrangement (130) for a turbine rotor blade (100) having a platform (110) at an interface between an airfoil (102) and a root (104), the root (104) including attachment means and a shank (112), wherein the platform (110) comprises a suction side (129) that includes a topside (113) extending from an airfoil base to a suction side slashface (122), and wherein the platform (110) overhangs a shank cavity (119). The platform cooling arrangement (130) may include: a pocket (160) formed in an underside region (114) of the platform (110), the pocket (160) comprising a mouth that fluidly communicates with the shank cavity (119); a manifold (162) extending from the suction side slashface (122) to a pressure side slashface (126), the manifold (162) including a connection to the pocket (160); and cooling apertures (156) that extend from connections made with the pocket (160) and manifold (162) to ports.</p> |
