ABSTRACT:
A rotor assembly for a gas turbine engine has platformless blades and the inner wall of the compressed air annulus is made up of separate annulus members bridging the spaces between pairs of adjacent blades. The invention provides salient feet on the annulus members which are fitted through the narrow necks of re-entrant grooves in a direction radially inwardly of the rotor disc. Wedges are slid between feet and the walls of the grooves to prevent removal of the feet and therefore the annulus members in a reciprocal direction.
