Abstract
An axial flow rotor disc apparatus of the radial blade entry type wherein bifurcated roots of the blades engage opposite sides of a circumferential rib member of the disc has shims or root liners between at least some of the blades for adjusting the blade spacing to match the circumference of the disc. The root liners are split into pairs for separate insertion from opposite sides of the rib member at convenient locations around the periphery of the disc, without requiring insertion at an entry slot for the blades. In one version of the apparatus, the liners are retained against the rib member by deforming corners of the roots circumferentially over the liners. In another version, the liners have dogs that engage cavities in the adjacent root. The liners can also be joined along an interlocking split line for holding each pair together.
