Abstract

La présente invention concerne un véhicule aérien configuré pour voler à la fois verticalement et horizontalement, approprié pour lutter contre des incendies ou aider lors d'opérations de recherche et de sauvetage. Le véhicule aérien a une cellule, un arbre d'entraînement, un rotor ayant des pales qui permettent de faire varier l'angle de pas de chacune des pales, une transmission de puissance, une turbine à réaction et une aile. Dans la configuration de vol vertical, le rotor fournit une portance par rotation des pales par rapport à la cellule. Dans la configuration de vol horizontal, le rotor est sensiblement fixe et l'aile et les pales du rotor génèrent une portance verticale et un pas de commande, en lacet et/ou en roulis du véhicule aérien au fur et à mesure que la turbine à réaction fournit une poussée horizontale.
