Abstract (en)
[origin: FR2916482A1] The system (100) has a braking unit (110) provided with an abrasive element (110A), braking unit (120) with a ring shaped element (120A) made of susceptible material. The two braking units are integrated to a stator and a rotor, respectively. The braking units are contacted by an axial displacement of the rotor, after braking of a shaft. The abrasive element is eroded with the ring shape element. The braking unit is mounted on a stator support formed by an exhaust case (10).
