Abstract

A locking device arrangement for a rotating bladed stage is provided and includes a wheel formed to define a substantially circumferential slot and three slot sections, one of the slot sections including one radial slot and two lock slots to permit blade and blade lock installation along the circumferential slot, respectively, the other slot sections including a lock slot to permit blade lock installation along the circumferential slot, and the three slot sections being separated from one another with angular offsets such that the wheel is mass balanced substantially evenly about a desired center of rotation with the blade locks installed and to reduce accumulation of flowpath gaps.
