Abstract

L’invention concerne un volet pivotant (3) pour un ensemble vélique d’un véhicule maritime, le volet pivotant (3) étant destiné à équiper et collaborer – directement ou indirectement – avec une voile (2) de l’ensemble vélique , le volet pivotant (3) comportant un dispositif de pivotement (4) relativement à un axe de rotation situé le long d’un bord d’appui (31A) dudit volet pivotant (3), le dispositif de pivotement (4) comportant (i) au moins une vessie gonflable (41A, 41B) et un organe de contrôle d’un volume d’air injecté sélectivement dans chaque au moins une vessie gonflable (41A, 41B), de sorte à autoriser un gonflement ou un dégonflement de chaque vessie gonflable afin de générer un effort contre le bord d’appui (31A) afin de conduire à une rotation contrôlée dudit volet pivotant (3). Figure à publier avec l’abrégé : Fig. 7The invention relates to a pivoting flap (3) for a sailing assembly of a maritime vehicle, the pivoting flap (3) being intended to equip and collaborate – directly or indirectly – with a sail (2) of the sailing assembly, the pivoting flap (3) comprising a pivoting device (4) relative to an axis of rotation located along a bearing edge (31A) of said pivoting flap (3), the pivoting device (4) comprising (i) at least one inflatable bladder (41A, 41B) and a member for controlling a volume of air selectively injected into each at least one inflatable bladder (41A, 41B), so as to allow inflation or deflation of each inflatable bladder in order to generate a force against the bearing edge (31A) in order to lead to a controlled rotation of said pivoting flap (3). Figure to be published with the abstract: Fig. 7
