Abstract

The sail system is so designed that the action of the wind on the sail is directly transmitted to the moving body by means of supports in order to generate a propulsion force. It is comprised of one mast (1) serving as a pivot for two upper yards (6 and 7) arranged to form an X and for two lower yards (4 and 5) arranged in the same way. Two rectangular half sails (8 and 9), arranged on either side of the mast (1) are set between said yards. An identical rotation of the four yards provides a change of orientation of the sail. An opposite rotation of the yards of each X gives a change of sail surface area. A specific actuation device is provided either for an effortless manual control or for an automatic control. It may provide for a main or auxiliary propulsion for regata or leisure sailing boats, sailing carts, merchant vessels or trawlers.

Description

SYSTEME DE VOILURE DESTINE A LA PROPULSION DES NAVIRES OU DES VEHICULES TERRESTRES La présente invention concerne les dispositifs appelés voilures destinés à assurer la propulsion de navires ou même de véhicules terrestres à partir de l'énergie éolienne. Les variations locales de vitesse du vent dues à la présence de la voilure produisent des différences de pression entre les faces de la voilure. Ces différences de pression se traduisent par une force directement transmise au mobile par les supports de la voilure. Dans ce secteur, l'état de la technique est le suivant : il existe des voilures souples dont la mise en oeuvre est longue et compliquée et dont la manoeuvre peut présenter des dangers (risque d'empannage intempestif). De plus la réduction de voilure peut nécessiter des manoeuvres périlleuses (sur le pont d'un navire). Des focs à enrouleur représentent un progrès : ils sont plus faciles à mettre en oeuvre mais cela se paie par un moins bon rendement et, de plus, cela ne concerne pas toute la voilure. The present invention relates to devices called wings intended to propel ships or even land vehicles from wind energy. Local variations in wind speed due to the presence of the airfoil produce pressure differences between the faces of the airfoil. These pressure differences result in a force directly transmitted to the mobile by the wing supports. In this sector, the state of the art is as follows: there are flexible canopies whose implementation is long and complicated and whose operation can present dangers (risk of untimely jibe). In addition, the reduction of the airfoil may require perilous maneuvers (on the deck of a ship). Furling jibs represent an improvement: they are easier to implement but this is paid for by a lower efficiency and, moreover, this does not concern the whole wing.

En outre la manoeuvre des voilures souples classiques est difficilement mécanisable et très rapidement inaccessible à un homme seul, à partir d'une certaine taille.In addition, the operation of conventional flexible canopies is difficult to mechanize and very quickly inaccessible to a single man, from a certain size.

Il existe aussi des voilures rigides qui sont plus facilement mécanisables mais elles présentent un inconvénient majeur : la variation de surface est très difficile sinon impossible à prévoir. L'objet de la présente invention constitue un aboutissement ultime de ce type de voilure (dont il conserve la fiabilité) avant l'utilisation de voilures tournantes servant à actionner des hélices. Le système de voilure suivant la présente invention a pour but d'éliminer totalement le risque d'empannage et, plus généralement, de permettre des réglages et variations de surface de voilure accessiblés à un homme seul sans efforts ni manoeuvre dangereuse ou facilement mécanisables.There are also rigid canopies which are more easily mechanized, but they have a major drawback: the surface variation is very difficult if not impossible to predict. The object of the present invention constitutes an ultimate outcome of this type of wing (of which it retains reliability) before the use of rotary wings used to actuate propellers. The airfoil system according to the present invention aims to completely eliminate the risk of jibe and, more generally, to allow adjustments and variations of airfoil surface accessible to a single man without effort or dangerous maneuver or easily mechanized.

La réduction des efforts et l'aptitude à la mécanisation sont obtenues par les dispositions suivantes : l'ensemble de la voilure est sensiblement symétrique par rapport à l'axe de rotation donc très regroupé autour de cet axe, mis en oeuvre d'une manière unique, et en grande partie autocompensé. L'élimination du risque d'empannage est obtenue grâce a un dispositif qui peut être une girouette et tel qu'en cours de fonctionnement, le centre de poussée de la voilure soit toujours légèrement au vent de l'axe de rotation. La voilure selon la présente invention comporte deux demivoilures 8 et 9 (figure 2). Elle est établie entre deux vergues supérieures 6 et 7 disposées en X et deux vergues inférieures 4 et 5 disposées de la même manière.The reduction of the forces and the aptitude for mechanization are obtained by the following arrangements: the whole of the airfoil is substantially symmetrical with respect to the axis of rotation therefore very grouped around this axis, implemented in a manner unique, and largely self-compensated. Elimination of the risk of jibe is obtained thanks to a device which can be a wind vane and such that during operation, the center of thrust of the wing is always slightly to the wind from the axis of rotation. The wing according to the present invention comprises two half-wings 8 and 9 (FIG. 2). It is established between two upper yards 6 and 7 arranged in X and two lower yards 4 and 5 arranged in the same way.

Chaque vergue peut pivoter en son milieu autour du mât (axe de rotation) et supporte à une extrémité un tube enrouleur (10 ou 11) et à l'autre extrémité, le profilé de bord de fuite (14 ou 15).Each yard can pivot in its middle around the mast (axis of rotation) and supports at one end a winding tube (10 or 11) and at the other end, the trailing edge profile (14 or 15).

Les bords d'attaque peuvent être constitués par des carénages rigides 12 et 13 englobant les tubes enrouleurs.The leading edges can be constituted by rigid fairings 12 and 13 including the winding tubes.

L'orientation de la voilure est obtenue par une rotation identique des quatre vergues.The orientation of the blade is obtained by an identical rotation of the four yards.

La variation de surface de voilure est obtenue par rotations opposées des vergues du même X, des deux X étant modifiés de la même manière.The variation of sail area is obtained by opposite rotations of yards of the same X, of the two X being modified in the same way.

Quelle que soit la surface de voilure choisie, les demi-voilures sont sensiblement parallèles et pratiquement symétriques par rapport à l'axe de rotation (ou du mât, dans ce cas).Whatever the sail area chosen, the half-wings are substantially parallel and practically symmetrical with respect to the axis of rotation (or of the mast, in this case).

La réduction maximale de voilure peut donner une structure rigide de faible surface (figure 4). La surface maximale de voilure peut être obtenue quand les vergues d'un même X sont les diagonales-d'un carré ou perpendiculaires entre elles. L'espacement des demi-voilures est alors sensiblement égal à leur corde. Dans ces conditions, il n'y à pratiquement pas d'interférence nuisible entre les deux demi-voilures (voir ouvrages d'aérodynamique). La voilure selon l'invention est telle que son centre de poussée soit constamment, en cours de fonctionnement, légèrement au vent de l'axe de rotation et en particulier telle que, laissée en rotation libre, elle se mette en drapeau, bords d'attaque face au vent. Ce résultat peut être obtenu par une girouette 18, prévue pour rester constamment dans le plan de symétrie de la voilure. Le support de la voilure peut être constitué par un mât I équipé d'une potence 2, tenue par des haubans 3. Le dégagement ainsi obtenu permet la rotation de la voilure sur 360 degrés (figure 3). Au repos, la voilure peut être repliée à l'intérieur de la structure rigide (figure 4), en position dressée ou couchée (figure 5). La mise en oeuvre est ainsi grandement facilitée.The maximum reduction in airfoil can give a rigid structure with a small surface area (Figure 4). The maximum sail area can be obtained when the yards of the same X are diagonals-of a square or perpendicular to each other. The spacing of the half-wings is then substantially equal to their rope. Under these conditions, there is practically no harmful interference between the two half-wings (see aerodynamic works). The airfoil according to the invention is such that its center of thrust is constantly, during operation, slightly upwind of the axis of rotation and in particular such that, left in free rotation, it becomes feathered, edges of attack against the wind. This result can be obtained by a wind vane 18, designed to remain constantly in the plane of symmetry of the airfoil. The wing support can consist of a mast I fitted with a bracket 2, held by shrouds 3. The clearance thus obtained allows the rotation of the wing over 360 degrees (FIG. 3). At rest, the wing can be folded inside the rigid structure (Figure 4), in the upright or lying position (Figure 5). The implementation is thus greatly facilitated.

A titre indicatif, l'étarquage de la voilure peut être as- sure par des ressorts 16 et 17 ou tout autre système tel des vérins. L'ensemble de commande 21 (figure I) est détaillé sur les figures 6 et 7. Il est constitué de deux parties qui permettent l'orientation et la variation de surface de la voilure.As an indication, the spreading of the airfoil can be ensured by springs 16 and 17 or any other system such as jacks. The control assembly 21 (FIG. I) is detailed in FIGS. 6 and 7. It consists of two parts which allow the orientation and the surface variation of the wing.

La variante représentée est manuelle mais elle peut facilement être mécanisée et même automatisée moyennant des modifications mineures. Commande d'orientation : une couronne dentée 24, centrée sur l'axe de rotation, est solidaire de la vergue inférieure 4. Elle peut engrener sur une autre couronne dentée 25 solidaire d'un volant 26. L'ensemble formé par 25 et 26 peut être translaté en vue d'embrayer ou de débrayer la commande. Le volant 26 peut être bloqué en rotation par un frein 27 (position embrayée).The variant shown is manual but it can easily be mechanized and even automated with minor modifications. Orientation control: a ring gear 24, centered on the axis of rotation, is secured to the lower yard 4. It can mesh on another gear ring 25 secured to a flywheel 26. The assembly formed by 25 and 26 can be moved to engage or disengage the control. The steering wheel 26 can be locked in rotation by a brake 27 (engaged position).

Commande de variation de surface : une couronne dentée 28, centrée sur l'axe de rotation, est solidaire en rotation de deux poulies 29 et 30 ; elle peut engrener sur une autre couronne dentée 31 solidaire d'un volant 32. L'ensemble formé par 31 et 32 peut être translaté en vue de débrayer ou d'embrayer la commande. Le mouvement de rotation des poulies 29 et 30 est transmis par des courroies 22 et 23 aux poulies 19 et 20 actionnant les tubes enrouleurs.33 est un doigt de verrouillage agissant sur les cannelures de la couronne cannelée solidaire de 28 (voir figure 6). Il existe aussi des cannelures entre 28 et la pièce de révolution portant les poulies 29 et 30. Sur les figures 6 et 7 ces cannelures sont indiquées par un trait interrompu. 34 est un ressort.Surface variation control: a ring gear 28, centered on the axis of rotation, is rotationally integral with two pulleys 29 and 30; it can mesh on another ring gear 31 secured to a flywheel 32. The assembly formed by 31 and 32 can be translated in order to disengage or engage the control. The rotational movement of the pulleys 29 and 30 is transmitted by belts 22 and 23 to the pulleys 19 and 20 actuating the winding tubes. 33 is a locking finger acting on the grooves of the grooved crown integral with 28 (see FIG. 6). There are also grooves between 28 and the part of revolution carrying the pulleys 29 and 30. In Figures 6 and 7 these grooves are indicated by a dashed line. 34 is a spring.

Toutes les pièces représentées figures 6 et 7, exceptés le doigt 33, la vergue 4, le frein 27, sont de révolution autour d'un axe. La figure 6 correspond à une configuration : commandes débrayées, voilure libre en rotation. La figure 7 correspond à une configuration permettant le réglage de la surface.All the parts shown in Figures 6 and 7, except finger 33, yard 4, brake 27, are of revolution about an axis. Figure 6 corresponds to a configuration: disengaged controls, free wing in rotation. Figure 7 corresponds to a configuration for adjusting the surface.

Ce système de voilure peut assurer la propulsion principale ou d'appoint de bateaux de plaisance ou régate, de chars à voile, de navires marchands ou de chalutiers. This wing system can provide main or auxiliary propulsion for pleasure or regatta boats, sand yachts, merchant ships or trawlers.
