Abstract

The adjustable vanes are fixed at the ends (A,B) and joined by tie bars (3). The tie bars are joined to the hull (4). The tensioning system consists of two cables (9,10) and springs (11). One end is fixed to the hull and the outside end is connected to the top end of the vanes. The vanes (1,12) are anchored at two points (A,B) and the angles of the blades are varied by the wind strength and direction.

Description

DESCRIPTION
LA présente invention concerne les bateaux ou engins à voiles pourvues d'ailes marines. Elle à pour but de per mettre le réglage automatique et optimum de l'angle d'inclinaison des ailes portante s tenant compte en permanence de la vitesse de l'engin et de la force des poussées secondaires exercées sur la coque par les vents latéraux.
DESCRIPTION
The present invention relates to boats or gear with sails provided with marine wings. Its purpose is to allow the automatic and optimum adjustment of the angle of inclination of the bearing wings s constantly taking into account the speed of the craft and the force of the secondary thrusts exerted on the hull by the side winds.

Dans les dispositifs connus de ce genre, le réglage de l'angle d 'inclinaison des ailes portante s n'est pas automatique et requière des mises au point constantes. De plus les réglages ainsi opérés se font simultanement et indis tintement sur les deux ailes portantes à la fois, leur domzrnzt de la sorte le même angle d'inclinaison quelque soient les contraintes exercées sur chacune d'elle, d'où le peu d'efficacité du système.In known devices of this kind, the adjustment of the angle of inclination of the bearing wings s is not automatic and requires constant focusing. In addition, the adjustments thus made are made simultaneously and indiscriminately on the two bearing wings at the same time, their domzrnzt in this way the same angle of inclination whatever the stresses exerted on each of them, hence the lack of system efficiency.

Dans le dispositif exposé, objet de l'invention, le réglage se fait distinctement, automatiquement et de manière permanente sur chacune des ailes portantes. L'angle d'inclinaison sera donc variable pour chacune d'elle selon les con traîntes au quelles elles seront soumises. Dans leurs positions initiales la plus verticale, les ailes jouent à faible vitesse le role de dérive. Plus la vitesse augmente plus les ailes se replient vers l'interieur et plus elles deviennent porteuses pouvant alleger l'engin jus qu 'à son point de déjaugement.On pourra par le biais d'une simple com mande additionnelle, sous forme d'un mancie par exemple, agir sur la ligne de tension des ailes pour augmenter ou diminuer à la demande 1 'angle d 'inclinaison de l'une en opérant simultanément le contraire sur l'autre.De la sorte on obtiendra un système secondaire de corection ou de gîtidage qui rendra l'engin plus attractif ou plus maniable
Le dispositif comprend deux ailes portantes à inclinaison variable fixées l'une et l 'autre par articulation à chacune des extrémitées d'un bras de liaison maintenu transversalement à la coque. Chaque aile est constituée de deux parties: La partie immergée active d'incidence portante q'n va de la charnière de fixation au bas de l'aile et et la partie passive supérieure qui se trouve dans le prolongement de l'aile au dessus de la charnière.En agissant sur la partie supérieure de l'aile ou en reliant cette même partie à un système de tension on provoquera la modification Oit le con tro le permanent de l'angle dtin- clinaison de l'aile portante. De même selon les forces imprimées à l'aile dans sa partie immergée , compte tenu de la vitesse de l'engin et des pressions secondaires dates à la force des vents latéraux, celle-ci se pliera plus ou moins autour de son axe d'articulation.Elle ira selon les forces rencontrées de sa position initiale, où elle joue le roule de rérive, à la position la pbs s fermée autorisée par le système de tensions offrant ainsi tout au long de cette variation d'angle contrôlée par le système de tension, une portance optimume en rapport de la résultante des forces engendrées. A l'arret, sur terre ou au cours des manipulations de l'engin, on pourra décrocher les lignes de tension des ailes portantes et les replier le long des bras de liaison. Les dessins annexes illustrent à titre d'exemple un mode de réalisation conforme à la présente invention. Figure 1 . Le dispositif comporte deux ailes portantes 1 et 2 fixées au moyen d'articulations A et B aux bras de liaison 3 eux mimes solidaires de la coque 4.Les systèmes de tension 5 et 6 ainsi que 7 et 8 sont constitués dans cet exemple par deux cables 9 et 10 et deux ressorts 11. Ils sont fixés d'un coté aux extrémitées supérieures des ailes de l'autre coté sur la coque par une potence d'atache. Figure 2 : On peut voir les ailes portantes dans leurs positions de repli maximum autorisée par les systèmes de tension. L'engin à déjaugé dans des conditions idéales par vent portant sur son arrière. Figure 3 Un fort vent de travers imprime à l'engin une vitesse importante mais tend à le renverser.
In the exposed device, object of the invention, the adjustment is made distinctly, automatically and permanently on each of the bearing wings. The angle of inclination will therefore be variable for each of them according to the constraints to which they will be subjected. In their most vertical initial positions, the wings play the role of drift at low speed. The more the speed increases, the more the wings fold inwards and the more they become load-bearing, which can lighten the machine up to its planing point. We can by means of a simple additional command, in the form of a mancie for example, act on the line of tension of the wings to increase or decrease on demand the angle of inclination of one while simultaneously operating the opposite on the other. In this way we will obtain a secondary system of corection or that will make the machine more attractive or more manageable
The device comprises two bearing wings with variable inclination fixed one and the other by articulation at each of the ends of a link arm held transversely to the hull. Each wing consists of two parts: The active submerged bearing bearing q'n part goes from the fixing hinge to the bottom of the wing and the upper passive part which is in the extension of the wing above By acting on the upper part of the wing or by connecting this same part to a tension system, the modification will be caused. Or the permanent con tro of the angle of inclination of the bearing wing. In the same way according to the forces impressed on the wing in its submerged part, taking into account the speed of the craft and the secondary pressures dates to the force of the lateral winds, this one will bend more or less around its axis of articulation.Elle will go according to the forces encountered from its initial position, where it plays the roll of drift, to the closed position pbs s authorized by the tension system thus offering throughout this angle variation controlled by the system tension, an optimal lift in relation to the resultant of the forces generated. When stopped, on land or during handling of the machine, it will be possible to unhook the tension lines of the bearing wings and fold them along the link arms. The accompanying drawings illustrate by way of example an embodiment in accordance with the present invention. Figure 1 . The device comprises two bearing wings 1 and 2 fixed by means of articulations A and B to the link arms 3 which are likewise secured to the shell 4. The tension systems 5 and 6 as well as 7 and 8 are constituted in this example by two cables 9 and 10 and two springs 11. They are fixed on one side to the upper ends of the wings on the other side on the hull by an attachment bracket. Figure 2: The bearing wings can be seen in their maximum folding positions authorized by the tension systems. The machine planed in ideal conditions by wind bearing on its rear. Figure 3 A strong cross wind gives the machine a high speed but tends to overturn it.

L'aile portante 1 suporte une pression verticale résultante supérieure à celle que suporte l'aile portante 2 , ce qui aurait effet théorique de faire miter le bateau. Sous cette pression suXémentaire , l'aile 1 se referme plus que l'aile 2 et devient surporteuse, opposant à la résultante verticale des forces du vent une contre force d'équilibre qui redresse l'engin.The supporting wing 1 suffers from a resulting vertical pressure greater than that which the supporting wing 2 suffers, which would have the theoretical effect of causing the boat to miter. Under this additional pressure, the wing 1 closes more than the wing 2 and becomes overbearing, opposing the vertical result of the wind forces a counterbalancing force which straightens the craft.

L'invention peut être utilisée sur toutes embarcations ou engins à voiles en vue d'en augmenter considérablement vitesse sécurité et attracti vi té. The invention can be used on any boat or sailboat with a view to considerably increasing its speed, safety and attractiveness.
