Abstract

L'invention est relative à un rotor d'aéronef à ailes rotatives, ledit rotor comportant un mât rotor (20), d'axe longitudinal Z, pour le support de pales (30) et un dispositif de commande (100) des pales. Le rotor comporte un détecteur de position angulaire (21) du mât. Le dispositif de commande (100) des pales comporte un actionneur (10) par pale, chaque pale étant reliée au mât rotor par un arbre de pale (40) fixe d'axe radial X sensiblement perpendiculaire à l'axe longitudinal Z, chaque actionneur étant adapté à provoquer un déplacement commandé d'une pale angulairement autour de l'axe radial X et chaque actionneur étant disposé à hauteur de la pale associée.
