METHOD AND SYSTEM FOR THE STATIONARY FLYING 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 hovering system (1) for rotary wing aircraft (10). A first mode of operation makes it possible, when the longitudinal speed Ux of said aircraft (10) is greater than a first threshold speed Vseuil1, to approach a stop position S with a trajectory holding relative to the ground, the instructions of flight of an autopilot (15) being a ground road angle TKsol, a deceleration rate Ga of the forward speed Va of said aircraft (10), a slope P and a heading Ψ. A second operating mode makes it possible, when said longitudinal speed Ux is less than a second threshold speed Vseuil2, to hover at said stop position S with a heading behavior, said flight instructions being said longitudinal speed Ux , a lateral velocity VY, a vertical velocity Wz and said heading Ψ, said velocities Ux, VY and Wz being progressively reduced to zero speed after any action of a pilot of said aircraft (10).
