Abstract
A rotor blade having a cooled integral platform is disclosed. Various construction details are developed which disclose a rotor blade platform having a first cooling hole for directing rotor blade core cooling fluid over a first portion of the platform and a second cooling hole for directing under-platform cavity cooling fluid over a second portion of the platform. In a particular embodiment, a rotor blade platform includes a plurality of first cooling holes and a plurality of second cooling holes. The first cooling holes extend between a core cooling passage within the blade and the platform outer surface. The second cooling holes extend between a damper cavity and the platform outer surface. Both sets of cooling holes are oriented to direct a film of cooling fluid over the platform outer surface and individual cooling holes are aligned with flow streamlines of an interblade vortices to encourage the development of a film of cooling fluid.
