Abstract: 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), characterized 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.
