SYSTEM AND METHOD FOR FLIGHT CONTROL OF AN AIRCRAFT WITH A ROTATING SAILING SYSTEM WHILE TAKING A TRAJECTORY OR HOLDING A CAP, ACCORDING TO ITS SPEED OF PROGRESS

摘要

The present invention relates to a method and a flight control system (1) for rotary wing aircraft (10). A first mode of operation of said method makes it possible, when the longitudinal speed Ux of said aircraft (10) is greater than a first threshold speed Vseuil1, to perform a flight with a course of flight relative to the ground, the flight instructions of a pilot automatic (15) being a ground road angle TKsol, a forward speed Va, a slope P and a heading Ψ. A second mode of operation makes it possible, when said longitudinal speed Ux is less than a second threshold speed Vseuil2, to perform a flight with heading stability, said flight instructions being said longitudinal speed Ux, a lateral speed VY, a vertical speed Wz and said heading Ψ.
