METHOD FOR DRIVING A MAIN ROTOR OF GIRAVION IN THE FRAMEWORK OF A SIMULATION OF A CASE OF FAILURE OF ONE OF THE ENGINES OF THE GIRAVION

摘要

The present invention relates to a rotary drive method of a main rotor of a rotorcraft implementing a simulation mode in flight of a case of failure of one of the engines of the rotorcraft. In simulation mode and in the case where a current rotation speed (NR) of the main rotor is detected as lower than a threshold (S) of predetermined rotation speed, the simulation mode is kept active and a control command is generated. to cause a controlled progressive increase (A) of the power supplied by the motors by allowing a crossing of the limit imposed by an instruction (OEI / 2) for regulating the operation of the engine in simulation mode.
