Abstract
A longitudinal stack of gas turbine engine rotor disks each include an annular spacer which transmits compressive preloading of the stack to an adjacent disk, the spacer and an annular shoulder on the disk rim defining an annular slot which accommodates the base of a segmented annular blade cluster which shields the rim from some of the heat associated with the flow of working fluid around the disks.
