Abstract
A method of assembling a turbine for a turbine engine that includes mounting annular sectors around the blades to form an abradable ring that includes a groove in a sector of the annular sectors. The method also includes engaging a first wiper of a particular blade of the blades with the groove of the sector. The method further includes axially engaging an assembly comprising the blades and the annular sectors in a casing of a turbine, so that fixing members of the annular sectors cooperate with flanges of the casing to fix the annular sectors in the casing, around the blades. The fixing members comprise at least one upstream fixing member fixed on a radially internal facing side of an upstream end of the annular sectors and at least one downstream fixing member arranged at a downstream end of the annular sectors.
