Abstract:
1. A turbine blade comprising: a platform; an airfoil located on one side of the platform; and a base located on an opposing side of the platform, the base including an attachment portion that is receivable in a blade retention slot of a turbine disk and a shelf to be located outside the turbine disk, wherein the turbine blade includes a pressure side and an opposing suction side, and a mistake proof feature projects from a first outer surface of the shelf on one of the pressure side and the opposing suction side, wherein the mistake proof feature provides for proper installation of an adjacent turbine blade having an adjacent shelf, and a space is defined between the mistake proof feature and the adjacent shelf of the adjacent turbine blade, wherein a central longitudinal axis passes through a center of a width of a bottom surface of the base, wherein a distance between an opposing second outer surface of the shelf and the central longitudinal axis is less than a distance between the first outer surface and the central longitudinal axis.
