Abstract: An annulus filler for mounting to a rotor disc in a gas turbine engine includes a body portion having a top wall arranged to bridge the gap between two adjacent blades extending from the rotor disc and to define an air flow surface for air passing between the blades; and a separately formed rear interface portion, fixed to the body portion adjacent to a down-flow end of the top wall. The rear interface portion forms a lip projecting below the top wall.

Abstract: A stator vane for a gas turbine engine is provided. The stator vane has a platform surface from which an aerofoil extends, and a joggle surface that is circumferentially and radially displaced from the platform surface. Multiple stator vanes are arranged together to form a stator vane row, with each stator vane in the row remaining independent of the others. When the stator vanes are assembled together in a row, the joggle surface of one vane circumferentially overlaps a recess surface formed in a neighbouring vane. Because of the increased circumferential extent of the vanes, the vane is able to rotate in a retaining slot less than a conventional vane. This results in less wear and/or damage to the components.
