Patent ID: 8287239

Claim:
An annulus filler for mounting to a rotor disc of a gas turbine engine and for bridging a gap between two adjacent blades attached to the rotor disc, the annulus filler defining an airflow surface for air being drawn through the engine, the annulus filler comprising: one or more primary connectors for connecting the annulus filler to the rotor disc, and for resisting, in use, centrifugal forces on the annulus filler, each of the one or more primary connectors allowing rotation of the annulus filler around a centre line of the engine relative to the rotor disc at that primary connector; and a secondary connector formed at an axial end of the annulus filler for connecting the annulus filler to the rotor disc and for resisting, in use, motion of the annulus filler relative to the rotor disc in a first axial direction, the secondary connector allowing rotation of the annulus filler around the centre line of the engine relative to the rotor disc at the secondary connector.
