Abstract:
1. A sealing arrangement between a stator assembly and a rotor of a gas turbine engine, the rotor being rotatable about an engine axis, the stator assembly comprising vanes mounted at their radially inner ends on a vane support structure, and the rotor comprising blades mounted at their radially inner ends on a blade platform, the sealing arrangement comprising a sealing ring fixed to the vane support structure and extending around the engine axis, the sealing ring projecting axially from the support structure to a position axially beyond a circumferential edge of the blade platform and radially inwards of the blade platform, wherein the sealing ring is flexible so as to be capable of deflecting over the blade platform during installation of the vane support structure in a direction radially inwards relative to the blade platform.
