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.

Abstract: An assembly includes a securing stud held by a locking key that rotates with the stud and is provided with bearing surfaces for sitting on an edge of one of the parts to be assembled.

Abstract: A turbine for a turbine engine, the turbine comprising a rotor including blades the radially external periphery of which includes at least one first wiper radially extending outwards, sealing means radially extending about the blades and including a ring made of abradable material, with the radially external ends of the wipers cooperating with said ring made of abradable material so as to form a labyrinth-type seal, wherein said ring includes at least one first portion axially extending upstream of the first wiper and a second portion, different from the first portion, axially extending downstream of the first wiper, with the first portion and/or the second portion including a groove, wherein the first wiper has been inserted, with said groove being defined by the first portion and by the second portion.

Abstract: The present invention relates to a turbine assembly (10) of a turbine engine (1), comprising at least: a first bladed rotor (12), a bladed stator (13) and a second bladed rotor (14) arranged in series, the rotors (12, 14) being mounted on a shaft (2); a sealing plate (20) extending between the stator (13) and the shaft (2) and separating a first recess (C1) arranged between the first rotor (12) and the stator (13), from a second recess (C2) arranged between the stator (13) and the second rotor (14); and pressure-reducing means (300, 31) positioned inside the first recess (C1), the assembly being characterized in that said pressure-reducing means (300, 31) comprise a plurality of substantially radial recompression fins (300) extending into the first recess (C1).

Abstract: An assembly including a securing stud held by a locking key that rotates with the stud and is provided with bearing surfaces for sitting on an edge of one of the parts to be assembled. Sufficient clamping torque can be introduced without risk of damage and at the same time avoiding excessive screwing of the stud.

Abstract: A turbine for a turbine engine is disclosed, comprising a casing and a rotor comprising blades, the radially external periphery of which comprises at least one first wiper extending radially outwards, sealing means extending radially around the blades and comprising a ring made from abradable material, the radially external ends of the first wipers being engaged in a groove in said ring made from abradable material so as to form a labyrinth-type seal, wherein said ring is formed by a plurality of contiguous annular sectors, each sector comprising at least one fixing member cooperating with at least one complementary attachment flange of the casing so as to provide mounting of each sector on the casing by axial movement of said sector with respect to the casing, the casing being configured so as to allow the mounting of the sectors in the casing solely by axial movement of said sectors.
