Method of controlling the wing flaps and horizontal stabilizer of a hybrid helicopter

摘要

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.

1. A method of controlling a high-speed rotary wing aircraft, the aircraft comprising:
a fuselage; at least one main rotor having a plurality of blades; at least one variable-pitch propulsive propeller; at least two half-wings positioned on either side of said fuselage; aerodynamic control means of said aircraft comprising at least one movable flap on each half-wing, and at least one system for operating said flaps; at least one horizontal stabilizer positioned at one end of said aircraft, said horizontal stabilizer having at least one movable surface; and at least one power plant driving said main rotor and each propulsive propeller in rotation; the method comprising the following steps: determining the total lift of the aircraft assuming that said total lift counters the weight of said aircraft; and adjusting the lift of each half-wing by acting on said system for controlling said flaps so that (i) said lift of said half-wings is equal to a first predetermined percentage of said total lift of said aircraft during a stage of stabilized flight and (ii) the lift of each half-wing is different such that a difference in lift is between two half-wings, the difference in lift between said two half-wings serving to compensate for the effects of said main rotor affecting said half-wings differently.
