| 主权项 | 1. An annulus filler element for a rotor of a turbomachine, the annulus filler element mounted in use between adjacent blades of the rotor, the annulus filler element comprising: a lid portion having a radially outwardly facing surface which in use forms an inner wall of a flow annulus of the rotor between adjacent blades, the lid portion having an upstream end; a nose cone attachment portion extending in an upstream direction from the outwardly facing surface of the upstream end of the lid portion which in use is connected to a nose cone of the turbomachine; and a flange extending in a substantially radial direction from the upstream end of the lid portion which in use is connected to a disc of the rotor. | ||
