ABSTRACT:
A liquid cooled turbine bucket is provided with a plurality of generally radially extending subsurface coolant channels which are supplied with liquid coolant from a manifold in the bucket tip portion. Liquid coolant is delivered directly and solely to the bucket tip manifold via conduit means extending through the root and core portions of the bucket. The liquid coolant in the coolant channels removes heat from the turbine bucket by pool boiling, the resulting vapor being collected in vapor manifolds disposed radially inwardly from the channels and exhausted from the bucket.
