Abstract: A rotor for a rotary wing aircraft having a single blade with a longitudinal pitch axis and that is hinge mounted on the rotary shaft for rotating the rotor, the hinge being about an axis that is transversal relative to the rotary shaft, said rotary wing describing a cone when its pitch angle is not zero, the rotor possessing a balancing flyweight device for balancing the resultant of the horizontal component of the lift force and of the rotary drag force of the blade, the device being mounted to rotate with the rotary wing about its rotary shaft and, under the effect of the centrifugal force to which it is subjected while the rotary wing is rotating, generating a horizontal force that is applied to the rotary shaft of the motor and that opposes the above-mentioned resultant with a magnitude of that is a function of the position of the flyweight(s) of the balancing device relative to the rotary shaft of the rotor.

Abstract: Disclosed is an aerodyne including a supporting structure, to which are connected: at least one supporting axial blower, attached to the supporting structure; at least one main engine driving the supporting blower; at least three attitude blowers controlling roll and pitch, each attitude blower having an electrical motor and being attached, respectively, to one of the elongate arms that are distributed in a laterally, outwardly projecting manner around the supporting structure, to which each arm is connected by an inner end portion, the axis of rotation of each attitude blower being attached relative to the supporting structure, and all the attitude blowers being located outside the space centrally occupied by the supporting blower; at least one battery for supplying power to the electrical motors of the attitude blowers; a landing gear attached under the supporting structure; and a nacelle for holding the battery and a payload.
