Abstract

On présente un dispositif de freinage, dans un moteur à turbine à gaz, d'une turbine comprenant un rotor entraînant un arbre mobile en rotation par rapport à un stator, en cas de rupture dudit arbre. Le dispositif est caractérisé par le fait qu'il comprend un premier organe de freinage (110) pourvu d'au moins un élément abrasif (110A) et un second organe de freinage (120) comprenant un élément en forme d'anneau (120A) réalisé en un matériau susceptible d'être érodé par l'élément abrasif (110A), les deux organes de freinage étant solidaires l'un du rotor, l'autre du stator et venant en contact par déplacement axial du rotor après rupture de l'arbre, l'élément abrasif (110A) du premier organe de freinage (110) érodant l'élément en forme d'anneau (120) du second organe de freinage (120).

A braking device is presented in a gas turbine engine of a turbine comprising a rotor driving a shaft movable in rotation with respect to a stator, in the event of rupture of said shaft. The device is characterized in that it comprises a first braking member (110) provided with at least one abrasive element (110A) and a second braking member (120) comprising a ring-shaped element (120A). made of a material that can be eroded by the abrasive element (110A), the two braking members being secured to one of the rotor, the other of the stator and coming into contact by axial displacement of the rotor after breaking the shaft, the abrasive element (110A) of the first braking member (110) eroding the ring-shaped member (120) of the second braking member (120).
