Abstract

Une méthode de déplacement de rotors dun aéronef entre un mode de vol et un mode daéronef comprend la rotation dun axe raccordé en relation dentraînement aux rotors autour dun axe pour déplacer les rotors entre le mode de vol et le mode daéronef jusquà ce quun composant mobile avec laxe entre en contact avec une butée de laéronef et applique une charge contre la butée. La méthode comprend le maintien du composant contre la butée pour maintenir la charge appliquée contre la butée. Il est également décrit un aéronef.
