Turbine braking system for gas turbine engine, has two braking units integrated to stator and rotor, respectively and abrasive element eroded with ring shaped element, where braking units are contacted by axial displacement of rotor

摘要

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).
