A rotor assembly, for a gas turbine, has a plurality of rotor discs interconnected by an axially extending rim. The outside of the rim has a circumferential array of dovetail slots and the underside of the rim has 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. There is an array of blades, each blade having a blade root secured in a respective one of the dovetail slots. |
