초록 ▼

A bucket assembly for a turbine system is disclosed. The bucket assembly includes a main body having an exterior surface and defining a main cooling circuit, and a platform surrounding the main body and at least partially defining a platform cooling circuit. The platform includes a forward portion and an aft portion each extending between a pressure side slash face and a suction side slash face. The platform further includes a forward face, an aft face, and a top face. The bucket assembly further includes a passage defined in the aft portion of the platform. The passage is in fluid communication with one of the main cooling circuit or the platform cooling circuit.
