发明名称 Annulus filler
摘要 A rotor assembly for a gas turbine engine, the rotor assembly has a disc supporting a plurality of radially extending blades. The blades define passages therebetween and each passage has an annulus filler assembly. The annulus filler assembly includes at least two bodies and a brace, each of the bodies being arranged to abut respective adjacent blades and the brace is arranged to occupy a position centrally of the two bodies. The brace is mounted to the disc and each body and the brace are arranged to engage one another to form an airwash surface. The airwash surface improves aerodynamic flow of air entering the gas turbine engine.

主权项 1. A rotor assembly for a gas turbine engine, the rotor assembly comprising: a disc supporting a plurality of radially extending blades, the blades defining passages between their circumferentially-facing surfaces and each of these passages having an annulus filler assembly; and the annulus filler assembly comprising at least two bodies and a brace, each of the bodies being mounted to one of adjacent said blades and the brace occupying a position centrally of the at least two bodies, each of the bodies and the brace interacting with one another to form an airwash surface, the interaction of the brace with at least one said body forming a floating and moveable seal, the seal having a lip arranged to overlap a co-operating feature, and the feature having a radially outer opposing wall and a radially inner opposing wall to define a slot by way of a radial gap between the opposing walls and the lip being located centrally therebetween so as to be within the slot and movable relative to the opposing walls.
