Thermal plug for turbine bucket shank cavity and related method

A turbine rotor disk includes a row of buckets (10) secured about a radially outer periphery of the rotor disk, each bucket (10) having an airfoil (14), a platform (16), a shank (18) and a mounting portion (20), the mounting portion (20) received in a radial slot formed in the rotor disk such that a...

Beschreibung
Zusammenfassung:	A turbine rotor disk includes a row of buckets (10) secured about a radially outer periphery of the rotor disk, each bucket (10) having an airfoil (14), a platform (16), a shank (18) and a mounting portion (20), the mounting portion (20) received in a radial slot formed in the rotor disk such that adjacent buckets (10) in adjacent radial slots are separated by a rotor disk post located between adjacent mounting portions (20) and a shank cavity (46) between adjacent shanks, radially outward of the rotor disk post (12) and radially inward of adjacent platforms (16). The shank cavity (46) is substantially filled with at least one discrete thermal plug (56).
