Abstract:
1. A turbine bucket for use with a gas turbine engine, comprising: a platform; an airfoil extending from the platform; and a plurality of cooling circuits extending through the platform and the airfoil; wherein one of the plurality of cooling circuits comprises one or more airfoil cooling channels within the airfoil and a serpentine cooling channel within the platform; wherein the serpentine cooling channel comprises a cooling feed input configured to receive cooling air from a single one of the airfoil cooling channels and a plurality of film cooling holes configured to exhaust the cooling air to a top surface of the platform, such that the cooling air is exhausted at a pressure side of the airfoil, the cooling feed input forming a first cooling path portion extending adjacent to an edge of the platform, such that an end of the cooling feed input leads to an outlet of the platform and corresponds to a start of a second cooling path portion comprising a first leg, a second leg, and a third leg.
