Low weight control stage for high temperature steam turbines, has blade molding section equipped with steam turbine bucket attached to rotor dovetail, such that rotor dovetail corresponds to first dovetail

摘要

A blade molding section (24) is equipped with a steam turbine bucket (14) attached to a rotor dovetail (22), such that rotor dovetail corresponds the shape of a first dovetail (20). An internal cavity is extended from a radius platform (18) up to the front end of the bucket.
