Abstract

La présente invention concerne un procédé et un dispositif d’estimation d’une vitesse air d’un giravion (10) par analyse de son rotor (11). Ledit giravion comporte un fuselage et un rotor principal (11) muni d’une pluralité de pales (14) et tournant autour d’un axe (A1) d’un moyeu (13) du rotor (11) et dont l’extrémité (142) libre de chaque pale (14) décrit une trajectoire voisine d’un plan du disque (TPP). Ledit procédé permet de déterminer ladite vitesse air dudit giravion (10) dans un repère (X, Y, Z) solidaire dudit plan du disque (TPP) par résolution d’un modèle dudit rotor (11) mettant en relation un angle ( ) de pas d’au moins une pale (14) par rapport audit plan du disque (TPP) avec ladite vitesse air dudit giravion (10) et avec une vitesse auxiliaire. Ladite vitesse auxiliaire peut être une vitesse induite de l’air traversant ledit rotor (11) ou bien une vitesse axiale par rapport à l’air à l’infini amont dudit giravion (10).
