Abstract

L'invention porte sur un dispositif de levage amélioré composé d'un matériau étanche à l'air dur mou à trois couches ayant une faible densité. Un matériau de la couche intermédiaire et un matériau de la couche la plus à l'intérieur sont entourés d'un matériau de la couche la plus à l'extérieur. De l'air comprimé est introduit dans l'espace entouré par le matériau de la couche la plus à l'extérieur et le matériau de la couche intermédiaire pour étendre le matériau de la couche la plus à l'extérieur pour former une ligne d'écoulement lisse. Le dispositif de levage peut maintenir une meilleure ligne d'écoulement dans un procédé de vol à grande vitesse pour réduire la résistance au vol. La structure du dispositif de levage est améliorée de façon à garantir que le dispositif de levage est déployé facilement après avoir été gonflé et que le volume d'une grande cavité ne sera pas réduit considérablement pour accroître le poids de la charge du dispositif de levage.
