Abstract
A method of controlling a high-speed rotary wing aircraft (1) comprising a fuselage (2), at least one main rotor (3), at least one variable-pitch propulsive propeller (4), at least two half-wings (11, 11′) positioned on either side of said fuselage (2), at least one horizontal stabilizer (20) provided with a movable surface (21, 21′), and at least one power plant driving said main rotor (3) and said propulsive propeller (4) in rotation. Said method serves to adjust the lift of said half-wings (11, 11′) and the lift of the horizontal stabilizer (20) so that said lift of said half-wings (11, 11′) represents a predetermined percentage of the total lift of said aircraft (1) and so that the power consumed by said main rotor (3) is equal to a setpoint power during a stage of stabilized flight.
