Abstract: A method for dynamically converting the attitude of a rotary-wing drone that includes a body including an electronic board controlling the piloting of the drone and four link arms forming lift-producing wings, each arm including a rigidly connected propulsion unit. The method includes executing, on reception of an instruction allowing a conversion between flight using the rotary wings and flight using the lift of the wings, the conversion being defined by a pitch angle to be achieved θref, of a repeated sequence of steps until the pitch angle θref is achieved, including estimating the current pitch angle θest of the drone, determining an angular trajectory depending on the pitch angle to be achieved θref, and sending one or more differentiated commands based upon the angular trajectory and the current estimated pitch angle θest to one or more propulsion units such that the drone is rotated about the pitch axis.
