Abstract (en)
A turbomachine bucket includes a base portion (56) having a first end that extends to a second end, and an airfoil portion (58) extending from the first end of the base portion (56). The airfoil portion (58) includes a first end section (68) that extends to a tip section. A plurality of cooling channels (80) extend through the turbomachine bucket from the first end of the base portion (56) to the tip portion, and a cooling flow control member is arranged in one of the plurality of cooling channels (80). The cooling flow control member creates at least a partial flow restriction in the one of the plurality of cooling channels (80) to modify cooling flow passing through the turbomachine bucket.
