COOLING FLOW CONTROL MEMBERS FOR TURBOMACHINE BUCKETS AND METHOD

摘要

A turbomachine bucket includes a base portion having a first end that extends to a second end, and an airfoil portion extending from the first end of the base portion. The airfoil portion includes a first end section that extends to a tip section. A plurality of cooling channels extend through the turbomachine bucket from the first end of the base portion to the tip portion, and a cooling flow control member is arranged in one of the plurality of cooling channels. The cooling flow control member creates at least a partial flow restriction in the one of the plurality of cooling channels to modify cooling flow passing through the turbomachine bucket.
