  "textContent": "A rotor assembly, particularly for a gas turbine, comprising: a plurality of rotor discs interconnected by an axially extending rim, the outside of the rim having a circumferential array of dovetail slots and the underside of the rim having a circumferential channel which extends radially part way into the slots, the respective discs thus being interconnected axially across the channel by an array of circumferentially spaced connecting portions; an array of blades, each blade having a blade root secured in a respective one of the dovetail slots. According to one aspect of the invention, the rotor assembly comprises an annulus filler assembly, comprising: an annulus filler supported on the outside of rim, in-between adjacent blades, so as to form part of the inner wall of a respective flow annulus, the annulus filler additionally being anchored on the underside of the rim by an anchor element which is connected to the annulus filler through a clearance hole in a respective one of the connecting portions.",
