Abstract:
A turbine of a gas turbine engine comprising a stator sealing ring element arranged so as to form a labyrinth sealing joint in combination with at least one wiper, rotatable about the axis of the sealing ring. The element includes an abradable material layer with a surface portion engageable with said movable wiper. The abradable material layer on the surface portion axially includes a first area having a first wiper penetration resistance, said first area corresponding to the axial position of the wiper during nominal operation of the turbine, and a second area adjacent to the first area) and having lower wiper penetration resistance than the first area. The second area is located downstream from the first area and corresponds to the axial position that the wiper takes when a flame goes out in the combustion chamber of the engine.

Claim (Index 1):
A turbine of a gas turbine engine, comprising a stator sealing ring element arranged to form a labyrinth seal in conjunction with at least one wiper rotatable around the axis of the sealing ring, said stator sealing ring element comprising a layer of abradable material with a sealing surface portion capable of interacting with said moving wiper, wherein the layer of abradable material on said surface portion comprises axially a first zone with a first resistance to penetration of a wiper, said first zone corresponding to the axial position of the wiper in nominal operation of the turbine, and a second zone adjacent to the first zone with a reduced resistance to penetration of a wiper relative to the first zone, said second zone being located downstream relative to the first zone and corresponding to the axial position that the wiper assumes when flame extinction occurs in the combustion chamber of the engine.
