Method of assisted piloting of a rotary wing aircraft having at least one propulsion propeller, an assisted piloting device, and an aircraft

Abstract

A device () for assisted piloting of an aircraft having a rotary wing with a plurality of second blades (') and a propulsion unit with a plurality of first blades (′). The device includes control means () for delivering a movement order (O) for moving in a direction, said device () having a processor unit () for transforming said order (O) into an acceleration setpoint (C) along said direction, and then for transforming said acceleration setpoint (C) into at least one required longitudinal attitude setpoint (θ*) that is transmitted to a first automatic system () for maintaining longitudinal attitude by controlling a longitudinal cyclic pitch of the second blades (′), and into a first required load factor setpoint (Nx*) in a longitudinal direction that is transmitted to a second automatic system () for maintaining load factor by controlling the collective pitch of the first blades.
