Domaine technique Technical area
La présente invention concerne le domaine des voiles pour tout type de navires, engins, véhicules ou embarcations. L' invention se rapporte plus particulièrement à un The present invention relates to the field of sails for all types of ships, vehicles, vehicles or boats. The invention relates more particularly to a
dispositif permettant d'allonger, sur n'importe quelle voile, la longueur de l'extrados par rapport à l'intrados, augmentant de ce fait la dépression de cet extrados, et donc la puissance vélique de ladite voile. device for extending, on any sail, the length of the extrados relative to the intrados, thereby increasing the vacuum of the upper surface, and therefore the power of said sailing sail.
Description du problème description of the problem
Les voiles actuelles, composées d'une seule couche de matériau - généralement textile - ont un rendement qui pourrait être largement augmenté en les dotant d'un profil proche de celui d'une aile d'avion. Leur manque de The current sails, composed of a single layer of material - generally textile - have a yield that could be greatly increased by giving them a profile close to that of an aircraft wing. Their lack of
puissance implique la nécessité d'une grande surface de toile, et donc de mâts extrêmement hauts, afin de pouvoir propulser les navires de manière satisfaisante. Par petit temps, lorsque le vent vient à faiblir, le déficit de puissance de ces voiles traditionnelles les rendent incapables d'apporter la force vélique nécessaire. Power implies the need for a large surface of canvas, and therefore of extremely high masts, in order to be able to propel the ships in a satisfactory way. In light weather, when the wind is weakening, the power deficit of these traditional sails makes them unable to provide the necessary sailing force.
Quant à l'aspiration - la portance - du profil d'aile d'avion, celui-ci pose le problème de la réversibilité lors du virement de bord. En effet, sur un avion, As for the suction - the lift - of the airplane wing profile, this poses the problem of reversibility when tacking. Indeed, on an airplane,
l'extrados - induisant une dépression - est situé au dessus de l'aile, et l'intrados - induisant une pression - est situé en dessous de l'aile, et ce en toutes the extrados - inducing a depression - is located above the wing, and the pressure-inducing surface - is located below the wing, and in all
circonstances . Dans le cas d'une voile, en revanche, l'aile - fût-elle textile - est positionnée verticalement. Lorsque le navire est bâbord amure, l'intrados doit se situer à bâbord, et l'extrados à tribord. A l'inverse, lorsque le bateau est tribord amure, l'intrados doit se situer à tribord et l'extrados à bâbord. Il s'agit donc d'adapter le profil à chaque virement de bord. circumstances. In the case of a sail, on the other hand, the wing - even textile - is positioned vertically. When the ship is port tack, the underside must be on the port side and the upper side on the starboard side. Conversely, when the boat is starboard tack, the intrados must be on the starboard side and the extrados on the port side. It is therefore a question of adapting the profile to each tack.
Description de l'état de la technique Un article dans le "Voile et Voiliers" du mois de juillet 2013 (numéro 509) présente un état des lieux de ce qu'on appelle les "voiles épaisses", c'est-à-dire les voiles qui tentent à apporter une solution au problème énoncé ci- dessus . Description of the state of the art An article in the "Voile et Voiliers" of July 2013 (number 509) presents an inventory of so-called "thick sails", that is to say the sails that attempt to provide a solution to the problem stated above.
Ces voiles peuvent se diviser en deux catégories : les ailes rigides, et les ailes souples (voiles textiles) . These sails can be divided into two categories: rigid wings, and soft wings (textile sails).

Très performantes, elles sont cependant inadaptées à la The rigid wings are of the type used, for example, for AC-45 or AC-72 for the America's Cup. They are composed of adjustable thick panels. Highly successful, they are, however, unsuitable for

These boats sail only in wind conditions precisely regulated (3 to 33 knots of wind, if the state of the sea allows).
Quant aux ailes souples, il en existe apparemment deux types à l'heure actuelle : As for flexible wings, there are apparently two types of them at the moment:

But de l'invention Purpose of the invention
La présente invention propose d'optimiser le rendement d'une voile - sa puissance vélique - en la dotant d'un dispositif spécifique permettant d'allonger son extrados The present invention proposes to optimize the performance of a sail - its sailing power - by providing it with a specific device for extending its upper surface.
Résumé de l'invention Summary of the invention
L'invention consiste en l'apposition, sur chaque côté d'une voile, de structures textile qui, en gonflant, forment une sorte de protubérance (une bulle, ou "bubble" en anglais) ayant pour but d'allonger l'extrados de ladite voile, et ainsi d'en augmenter la puissance vélique. Ces structures pourront être dénommées "bulle (s)" dans la suite de cet exposé. The invention consists in affixing, on each side of a sail, textile structures which, by swelling, form a kind of protuberance (a bubble, or "bubble" in English) for the purpose of extending the upper surface of said sail, and thus increase the power of the sail. These structures may be called "bubble (s)" in the rest of this presentation.
Ces structures se gonflent automatiquement grâce à la dépression présente sur l'extrados, et restent These structures inflate automatically thanks to the depression present on the extrados, and remain
naturellement dégonflées côté intrados, à cause de la pression exercée par le vent de ce côté. naturally deflated on the intrados side, because of the pressure exerted by the wind on this side.
On pourra éventuellement augmenter la pression à We can possibly increase the pressure to
l'intérieur de ces structures textiles grâce à des prises d'air situées dans leur partie avant (proche du mât ou de l'étai), ou encore dans leur partie supérieure (le haut de la voile) . Dans ce cas, un système de clapet permettra éventuellement d'obstruer ces prises d'air. On comprendra que seule une bulle située sur l'extrados - donc du côté opposé à l'amure - est gonflée en navigation, l'autre étant étouffée, soit par la pression de l'air, soir par obturation de sa prise d'air. inside these textile structures through air intakes located in their front part (close to the mast or the forestay), or in their upper part (the top of the sail). In this case, a valve system will eventually obstruct these air intakes. It will be understood that only a bubble located on the upper surface - therefore on the side opposite to the tack - is inflated in navigation, the other being stifled, either by the pressure of the air, at night by closing of its air intake .
On notera que ce système de gonflement est très proche de celui d'un parapente. It should be noted that this inflation system is very close to that of a paraglider.
Afin de faciliter le gonflement de la bulle côté extrados, celle-ci sera éventuellement percée d'une ou plusieurs ouvertures, permettent l'entrée d'air, et facilitant son décollement de la voile centrale. To facilitate the swelling of the bubble side extrados, it will eventually be pierced with one or more openings, allow the entry of air, and facilitating its detachment of the central sail.
Selon un autre mode de réalisation, la bulle est réalisée en textile percé de petit trous, par exemple de type According to another embodiment, the bubble is made of textile pierced with small holes, for example of the type
"mesh", laissant passer un flux d'air contrôlé. Il peut s'agir par exemple d'une toile de type trampoline. "mesh", letting through a controlled airflow. he can for example, a trampoline-type canvas.
Afin de faciliter l'écoulement laminaire du flux d'air, le bord de fuite et/ou le bord d'attaque pourrait être partiellement ouvert. In order to facilitate the laminar flow of the airflow, the trailing edge and / or the leading edge could be partially open.
Le nombre de compartiments par bulle peut varier de par exemple de 2 à 50, ce nombre n'étant cependant pas The number of compartments per bubble may vary, for example, from 2 to 50, but this number is not
limitatif . limiting.
Notons encore que selon le mât et le haubanage utilisé, il pourra-t-être nécessaire de découper les tuyères de sorte à ce qu'elles ne prennent pas appuis sur les barres de flèche, haubans, galhaubans, etc.. Note also that depending on the mast and the guying used, it may be necessary to cut the nozzles so that they do not take support on the spreaders, shrouds, shrouds, etc. ..
Selon un mode de réalisation de base de l'invention, les structures sont gonflées uniquement sur l'extrados. Cela signifie que celles situées sur l'intrados pendent sur la voile, entraînant une perturbation de l'écoulement du flux. Bien que cela ait moins d'importance du côté de l'intrados, deux modes de réalisation permettent d'éviter cet inconvénient. According to a basic embodiment of the invention, the structures are inflated only on the extrados. This means that those located on the intrados hang on the sail, causing a disruption of the flow flow. Although it is less important on the underside side, two embodiments make it possible to avoid this disadvantage.
Selon un autre mode de réalisation en effet, on propose un système de bandes circulant verticalement dans la According to another embodiment, a system of bands running vertically in the
structure et permettant d'étarquer la voile côté intrados. structure and allowing to set the sail side intrados.
Selon encore un autre mode de réalisation, qui favorise la performance pure, on prévoit la présence de deux voiles parallèles à hisser en alternance sur le même mât According to yet another embodiment, which promotes pure performance, provision is made for two parallel sails to be hoisted alternately on the same mast.
(présentant éventuellement deux rails de guindant) et sur la même bôme (présentant éventuellement deux rails de bôme) . La voile de bâbord présente la structure gonflable sur son côté bâbord, et celle de tribord, la structure gonflable sur son côté tribord. En navigation, les deux voiles sont dès lors envoyées et affalées en alternance. Si le système décrit au paragraphe précédent est parfait pour la course au large ou les grandes croisières, il est en revanche fort contraignant pour les parcours (possibly with two luff rails) and on the same boom (possibly with two boom rails). The port sail has the inflatable structure on its port side, and starboard side, the inflatable structure on its starboard side. In sailing, the two sails are then sent and slumped alternately. If the system described in the previous paragraph is perfect for offshore racing or large cruises, it is however very constraining for the courses
nécessitant de nombreux virement de bord. Dans ce cas, l'invention propose également, dans une forme de requiring a lot of tack. In this case, the invention also proposes, in a form of
réalisation, on pourrait faire en sorte que toutes les structures gonflables puissent être affalée soit sur bâbord, soit sur tribord, indépendamment de la grand voile elle-même . realization, one could ensure that all inflatable structures can be sloped either on port or starboard, regardless of the mainsail itself.
La figurée 1 illustre de manière schématique un mode de réalisation simplifié. Figure 1 schematically illustrates a simplified embodiment.
On illustre le dispositif de voilure comportant la voile 1 sur laquelle est partiellement appliquée une structure en toile 2 formant des compartiments ou caissons 3 délimités par des membranes (voir nervures 5) , par la voile 1 et par la toile 2. On prévoit des oeillets 4 permettant  The wing device comprising the sail 1 on which is partially applied a fabric structure 2 forming compartments or caissons 3 delimited by membranes (see ribs 5), by the sail 1 and by the fabric 2 is illustrated.

Dans ce cas, les tuyères, caissons ou compartiments seront éventuellement percées d'oeillets (4) à un endroit neutre - généralement dans la moitié située du côté du bord de fuite - afin de permettre au textile de se plaquer contre la voile du côté de l'intrados, et de se décoller de celle-ci du côté de l'extrados. automatic, managing the opening and closing of these valves depending on the angle of the mast with respect to the wind, or the pressure / depression on the lower surface and the upper surface according to a preferred embodiment of the invention the structure allows to inflate / deflate the upper and lower surfaces without injection of air pressure, simply by playing on the depression of the extrados side, and on the pressure of the intrados side. In this case, the nozzles, caissons or compartments will be possibly pierced with eyelets (4) in a neutral position - generally in the half located on the trailing edge side - in order to allow the textile to press against the sail on the underside side, and to detach itself from this. on the side of the extrados.
