Abstract

L'invention concerne un bras (10) comprenant un premier sous-bras (12), un second sous-bras (14) et un manchon (16) ; le second sous-bras (14) est raccordé en rotation au premier sous-bras (12) ; un joint de raccordement (13) est formé entre le premier sous-bras (12) et le second sous-bras (14) ; le premier sous-bras (12) et le second sous-bras (14) sont tournés vers une même ligne droite de manière à déplier le bras (10) ; le second sous-bras (14) est tourné vers une position dans laquelle un angle entre le second sous-bras et le premier sous-bras (12) est inférieur à 180 degrés de manière à plier le bras (10) ; le manchon (16) est emmanché sur le second sous-bras (14) ; le manchon (16) coulisse en direction du premier sous-bras (12) lorsque le bras est déplié, traverse transversalement le joint de raccordement (13) et est raccordé par filetage au premier sous-bras (12) de manière à fixer le premier sous-bras (12) et le second sous-bras (14) sans fantôme, et le bras ne sera par conséquent pas plié pendant le vol. Le bras présente une bonne stabilité de manière à faciliter l'amélioration de la sécurité d'un véhicule aérien sans pilote pendant le vol. L'invention concerne également un véhicule aérien sans pilote comprenant le bras.
