Description
La présente invention concerne la navigation à voile. Il s'agit d'uneThe present invention relates to sailing. It's about a
structure de voile profilée, de type aile d'avion, à profil variable en fonction de la direction et de l'intensité du vent, et d'un accastillage permettant son gréement, son réglage et la réduction de la voilure (ou prise profiled sail structure, of the airplane wing type, with variable profile depending on the direction and intensity of the wind, and fittings allowing its rigging, its adjustment and the reduction of the sail (or taken

La plupart des voiles utilisées dans la navigation nautique ne sont pas des voiles profilées. Il existe cependant quelques études concernant la mise au point de voiles de ce type, certaines permettant même le changement d'amure, c'est à dire qu'elles présentent un profil asymétrique réversible, plus convexe sous le vent que le vent vienne d'un côté ou de l'autre; mais leur mécanisme est souvent compliqué, ou ils ne permettent pas la prise de ris ou leur Most of the sails used in nautical navigation are not profiled sails. However, there are some studies concerning the development of sails of this type, some even allowing the change of tack, that is to say that they have an asymmetrical reversible profile, more convex downwind than the wind comes from. one side or the other; but their mechanism is often complicated, or they do not allow reefing or their

La structure de voile selon l'invention présente une section profilée, adaptée au changement The sail structure according to the invention has a profiled section, adapted to change
d'amure, de plus son gréement et la réduction de la voilure sont aisés. of tack, moreover its rigging and the reduction of the sail are easy.
La voile selon l'invention se compose essentiellement des éléments suivants: le mat bord d'attaque, le mât bord de chute, la têtière, les toiles gauches et droites montées sur enrouleur, un ensemble de barres horizontales qui relient le bord d'attaque au bord de chute et enfin les cordages et poulies qui permettent le gréement, la prise de ris et le réglage de la tension des toiles. Les barres horizontales, régulièrement espacées le long de la hauteur de l'aile permettent de maintenir l'écartement entre le bord d'attaque et le bord de chute, mais aussi de rigidifier The sail according to the invention essentially consists of the following elements: the leading edge mast, the falling edge mast, the headrest, the left and right fabrics mounted on a furler, a set of horizontal bars which connect the leading edge at the edge of the fall and finally the ropes and pulleys which allow the rigging, the reefing and the adjustment of the fabric tension. The horizontal bars, regularly spaced along the height of the wing allow to maintain the spacing between the leading edge and the falling edge, but also to stiffen
l'ensemble de la structure.the whole structure.
Les toiles sont montées sur un dispositif de type enrouleur incorporé dans le volume du bord d'attaque. Chaque toile est déroulée en tirant sur sa chute, vers l'arrière de l'aile, à l'aide de cordages. Un système de poulies permet de renvoyer ces cordages en pied de mât en passant par les barres et le mât. Ce dispositif permet de régler la tension de chaque toile de façon indépendante. Les toiles sont montées tangentiellement aux sections du bord d'attaque et du bord de fuite, de sorte à ne pas entraver les écoulements d'air. Entre le bord d'attaque et le bord de fuite, la toile ne touche plus aucun élément rigide, en particulier les barres horizontales ne les touchent pas, leur courbure ne dépend plus alors que de la tension de réglage et des zones de pression exercées par le vent. Ce qui permet de moins contrarier The fabrics are mounted on a reel-type device incorporated in the volume of the leading edge. Each canvas is unrolled by pulling its fall, towards the rear of the wing, using ropes. A pulley system allows these ropes to be returned to the mast base, passing through the bars and the mast. This device makes it possible to adjust the tension of each fabric independently. The fabrics are mounted tangentially to the sections of the leading edge and the trailing edge, so as not to obstruct the air flows. Between the leading edge and the trailing edge, the fabric no longer touches any rigid element, in particular the horizontal bars do not touch them, their curvature no longer depends only on the adjustment tension and the pressure zones exerted by the wind. Which makes it less annoying
l'écoulement des flux d'air que ne le ferait une courbure forcée. flow of air flows than a forced curvature would.
La têtière, de section profilée est montée au sommet du mât et du bord de chute. Elle permet d'assurer une bonne terminaison aérodynamique du haut de l'aile. Lors de son gréement, le bord supérieur de la toile recouvre le bord inférieur de la têtière, ceci doit permettre de The profile section headrest is mounted at the top of the mast and the drop edge. It ensures good aerodynamic termination from the top of the wing. When rigging, the upper edge of the canvas covers the lower edge of the headrest, this should allow
réduire les effets de faseyement du bord supérieur de la toile. reduce the fading effects of the upper edge of the fabric.
le bord inférieur des toiles glisse lors de son gréement dans une latte double qui le maintient. the lower edge of the fabrics slides when rigged in a double slat which holds it.

Les dessins en annexe illustrent l'invention: The accompanying drawings illustrate the invention:
La figure I représente la voile profilée en coupe. Figure I shows the profiled sail in section.
La figure 2 représente la voile profilée en vue de côté. Figure 2 shows the profiled sail in side view.
En référence à ces dessins, la structure de la voile profilée se compose d'un mât (1), d'un bord de chute (2), de 2 toiles tendues entre ces 2 espars (3). Le bord d'attaque et le bord de chute sont reliés entre eux par des barres (4) le long de leur hauteur et par une têtière (5) en leur sommet. Les toiles peuvent être montées sur un système à enrouleur (6) en tirant sur leur chute vers l'arrière au moyen de filins (7), l'action de ces filins est rapportée en pied de mât (8) par un système de poulies (9). Le bord inférieur des toiles glisse lors de son gréement dans une latte With reference to these drawings, the structure of the profiled sail consists of a mast (1), a drop edge (2), 2 fabrics stretched between these 2 spars (3). The leading edge and the falling edge are interconnected by bars (4) along their height and by a headrest (5) at their top. The fabrics can be mounted on a reel system (6) by pulling their fall backwards by means of ropes (7), the action of these ropes is reported at the foot of the mast (8) by a system of pulleys (9). The lower edge of the fabrics slides when rigged in a slat

Les dimensions de cette voile profilée sont comparables à celles des voiles traditionnelles. The dimensions of this profiled sail are comparable to those of traditional sails.

L'extrémité de l'aile est constituée par une têtière (5) de section profilée qui assure un The fall of each fabric is pulled towards the trailing edge by means of ropes (7), attached at the foot of the mast (8) by a system of pulleys (9), passing through the horizontal bars and the mast. The end of the wing is constituted by a headrest (5) of profiled section which ensures a
