1. A method for regulating a temperature of exhaust gases of a turbomachine, the method comprising:
regulating injection of fuel into a combustion chamber of the turbomachine so that the turbomachine generates a target thrust, and
regulating injection of mechanical power by an electric motor onto a shaft driven in rotation by a turbine, the electric motor being activated when a clearance between a casing and blades of the turbine exceeds a first threshold value.
