Abstract
A turbine airfoil (E-H) extends from a shank (E-H). A platform (E-H) brackets or surrounds a first portion of the shank (E-H). Opposed teeth () extend laterally from the platform (E-H) to engage respective slots () in a disk. Opposed teeth () extend laterally from a second portion of the shank () that extends below the platform (E-H) to engage other slots () in the disk. Thus the platform (E-H) and the shank (E-H) independently support their own centrifugal loads via their respective teeth. The platform may be formed in two portions (E-H,E-H), that are bonded to each other at matching end-walls () and/or via pins (G) passing through the shank (E-H). Coolant channels () may pass through the shank beside the pins (G).
