    摘要: The present invention provides a method of driving a main rotor (2) of a rotorcraft (1) in rotation. A regulation setpoint (C) for a power plant (3) used for driving the main rotor (2) at a variable speed of rotation is generated by a control unit (4) and is transmitted to a regulator unit (5) for regulating the operation of the power plant (3). The value of an initial setpoint (NRini) is generated progressively and continuously depending on variation in the current value of the density (D) of the ambient air outside the rotorcraft (1). The value of the initial setpoint (NRini) is potentially corrected depending on predefined flight conditions of the rotorcraft (1). Prior to being transmitted to the regulator unit (5), the value of the regulation setpoint (C) is preferably limited to a range of acceptable speeds for driving the main rotor (2) in rotation.
