摘要 |
The present invention relates to a device for, in a gas turbine engine, braking a turbine comprising a rotor driving a shaft capable of rotating with respect to a stator in the event of said shaft breaking. The device is one which 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 capable of being eroded by the abrasive element (110A), the two braking members being secured one of them to the rotor and the other to the stator and coming into contact with one another through axial displacement of the rotor once the shaft has broken, the abrasive element (110A) of the first braking member (110) eroding the ring-shaped element (120A) of the second braking member (120).
