Abstract
A segmented seal (36) is provided for sealing between two adjacent rotor disks (18, 20). The individual segments (36) includes sideplate members (42, 44) and integral hook members (50, 52) which engage the facing sides of the respective disks (18, 20). Strut members (60, 62) support the central portion (64) of the axially and circumferentially extending wall members (40) which collectively establish the radially inner gas boundary for an annular working fluid stream (30).
