A METHOD OF CONTROLLING A MAIN ROTOR OF A ROTORCRAFT AN ASSOCIATED CONTROL SYSTEM AND A ROTORCRAFT FITTED WITH SUCH A CONTROL SYSTEM

摘要

The present invention relates to a control system (1) for controlling a main rotor (11) of a rotary wing (10) for performing an automatic rotation flight stage of a rotary wing machine (10)A control member (2) movable over the amplitude of the positions between the two end physical stops and for controlling the collective pitch of the blades (13) of the main rotor (11);The blade 13 of the main rotor 11, which is called the " automatic rotation collective pitch " which makes the main rotor 11 rotatable at the optimum rotational speed with respect to the automatic rotation flight stage of the rotary wing 10, A calculation unit (3) for calculating a collective pitch angle with respect to the reference point; AndThe control member 2 generates a control set point for servo control of the current collective pitch of the blades 13 of the main rotor 11 with respect to the " automatic rotation collective pitch " (4) for servo-controlling the position of the control member (2) with respect to a predetermined position,;
