TURBINE ENGINE COMPRISING A DEVICE FOR BRAKING THE FAN ROTOR

摘要

The invention relates to a turbine engine comprising a fixed structure (7), a fan (1) rotor (3), having an axis (XX) of rotation, and emergency braking means (12, 13) of the rotor (3), in particular in the event of the loss of a blade of the fan (1), characterised in that said emergency braking means (12, 13) comprise a first (18) and a second (22) member supported by the fixed structure (7), said members (18, 22) respectively being configured so as to interact frictionally with a first (20) element which is complementary to the rotor (3), by forming a stop of the rotor (3) towards the rear along the axis (XX), and a second (24) element which is complementary to the rotor (3), by forming a stop of the rotor (3) towards the front along the axis (XX), when the emergency braking means (12, 13) are active.

1. Turbine engine comprising a fixed structure, a fan rotor having an axis of rotation, and emergency braking means of the rotor, said emergency braking means comprising a first and a second member supported by the fixed structure, said members respectively being configured so as to interact frictionally with a first element which is complementary to the rotor, by forming a stop of the rotor towards the rear along the axis, and a second element which is complementary to the rotor, by forming a stop of the rotor towards the front along the axis, when the emergency braking means are active, characterised in that it further comprises means which are arranged so as to release at least one of said members in translation relative to the fixed structure along the axis of rotation. in the direction opposite to that for which it forms a stop, when the emergency braking means are activated.
