Description

L'invention concerne un navire catamaran.The invention relates to a catamaran ship.

Ce navire comporte deux flotteurs profilés rendus solidaires par une liaison disposée au-dessus de la ligne de flottaison et est caractérisé en ce que chaque flotteur présente, sous la ligne de flottaison, un décrochement se prolongeant vers l'arrière de chaque flotteur et en ce qu'une lame rigide est fixée à la coque dans la zone arrière du navire sous cette ligne de flottaison, cette lame étant orientée sensi­blement suivant l'axe du navire, en formant un angle avec la verticale à la ligne de flottaison.This vessel comprises two profiled floats made integral by a link arranged above the waterline and is characterized in that each float has, under the waterline, a recess extending towards the rear of each float and in that a rigid blade is fixed to the hull in the aft area of the ship under this waterline, this blade being oriented substantially along the axis of the ship, at an angle with the vertical to the waterline.

Suivant une autre caractéristique de l'in­vention, la lame rigide est plane au moins en partie.According to another characteristic of the invention, the rigid blade is planar at least in part.

Suivant une autre caractéristique de l'in­vention, au moins une partie de la lame rigide forme un angle qui est sensiblement droit avec la verticale à la ligne de flottaison.According to another characteristic of the invention, at least part of the rigid blade forms an angle which is substantially straight with the vertical to the waterline.

Suivant une autre caractéristique de l'in­vention, la lame rigide est fixée aux flotteurs.According to another characteristic of the invention, the rigid blade is fixed to the floats.

Suivant une autre caractéristique de l'in­vention, la lame rigide orientée sensiblement suivant l'axe du navire, présente une incidence de son bord avant vers la ligne de flottaison.According to another characteristic of the invention, the rigid blade oriented substantially along the axis of the ship, has an incidence from its front edge towards the waterline.

Suivant une autre caractéristique de l'in­vention, le décrochement des flotteurs est situé en avant du centre de gravité du navire.According to another characteristic of the invention, the offset of the floats is located in forward of the ship's center of gravity.

Suivant une autre caractéristique de l'in­vention, la lame rigide est fixée à la coque par des moyens autorisant le réglage de son incidence.According to another characteristic of the invention, the rigid blade is fixed to the shell by means allowing the adjustment of its incidence.

  • FIG. 2 is a side view of this ship, in operation,
  • FIG. 3 is a bottom view of FIG. 2, showing in particular the lift zones of the ship in motion,
  • - Figures 4 and 5 are respectively sections along AA and BB of Figure 3.

La navire conforme à l'invention pourra être adapté à divers usages, à la plaisance, au transport des marchandises ou des personnes, ou à la pêche.The vessel according to the invention can be adapted to various uses, pleasure craft, the transport of goods or people, or fishing.

Ses particularités essentielles résident dans le fait qu'il permet d'aller en mer par mauvais temps, qu'il présente une plate-forme stable et qu'il permet de réduire les frais de combustible avec une vitesse de croisière élevée en réduisant ainsi les temps morts dans le cas de bateaux de pêche.Its essential characteristics lie in the fact that it allows to go to sea in bad weather, that it presents a stable platform and that it makes it possible to reduce the fuel costs with a high cruising speed thus reducing the time-outs in the case of fishing vessels.

En outre, il dispose d'une grande surface de travail qui est stable, la charge utile du navire pouvant être importante afin, dans le cas de bateaux de pêche, d'allonger le temps de pêche.In addition, it has a large working surface which is stable, the payload of the vessel can be large in order, in the case of fishing boats, to extend the fishing time.

La navire catamaran conforme à l'invention comporte une coque pourvue de deux flotteurs profilés 1, 2, qui sont reliés, au-dessus de la ligne de flot­taison, par un plateau 3, de préférence creux.The catamaran ship according to the invention comprises a hull provided with two profiled floats 1, 2, which are connected, above the waterline, by a plate 3, preferably hollow.

Conformément à l'invention, les flotteurs 1, 2 présentent, en-dessous de la ligne de flottaison 4, un décrochement 5 qui se prolonge jusqu'à l'arrière 6 de chaque flotteur. En outre, les deux flotteurs 1, 2 sont reliés par une lame rigide 7 qui, dans l'exemple représenté, est plane et qui est disposée à l'arrière du navire, sensiblement parallèlement à et sous la ligne de flottaison 4 mais avec une légère incidence de son bord avant vers la ligne de flottaison, afin de favoriser le soulèvement de l'avant du navire lorsqu'il se met en marche.According to the invention, the floats 1, 2 have, below the waterline 4, a recess 5 which extends to the rear 6 of each float. In addition, the two floats 1, 2 are connected by a rigid blade 7 which, in the example shown, is planar and which is disposed at the rear of the ship, substantially parallel to and below the waterline 4 but with a slight incidence of its front edge towards the waterline, in order to favor the lifting of the bow of the ship when it starts.

Cette lame pourra cependant être réalisée de formes, de dimensions et de dispositions très diver­ses, l'essentiel cependant étant que cette lame soit orientée suivant une direction 7₁ qui correspond sen­siblement à l'axe X-X de ce navire en formant un angle avec la verticale Y-Y à la ligne de flottaison 4.This blade can however be made of very different shapes, dimensions and arrangements, the main thing however being that this blade is oriented in a direction 7₁ which corresponds substantially to the axis XX of this vessel by forming an angle with the vertical YY at the waterline 4.

De cette construction il résulte que la sur­face de la projection orthogonale de cette lame sur un plan contenant la ligne de flottaison, détermine une surface portante à l'arrière du navire lorsque celui-­ci est en marche.From this construction it follows that the surface of the orthogonal projection of this blade on a plane containing the water line, determines a bearing surface at the rear of the ship when the latter is in operation.

Cette lame pourra ainsi être réalisée, au moins partiellement, suivant une forme courbe ou à l'aide de plusieurs surfaces planes réunies entre elles par des surfaces courbes ou des angles vifs.This blade can thus be produced, at least partially, in a curved shape or using several flat surfaces joined together by curved surfaces or sharp angles.

Suivant l'exemple représenté, la lame rigide 7 est également supportée à pivotement, par l'intermé­diaire d'un axe transversal 8, à l'extrémité inférieu­re de deux bras de faible épaisseur 9 fixés à l'extré­mité arrière du navire sous l'extrémité inférieure des flotteurs, afin d'être constamment profondément immer­gé dans l'eau. La lame rigide 7, montée à pivotement sur l'axe 8, est reliée par une transmission non représentée à un dispositif de commande actionnable par le pilote, ce dispositif de commande permettant un réglage fin de l'incidence de la lame 7 en fonction, notamment, de la charge du navire, de la répartition de cette charge et de la vitesse du navire.According to the example shown, the rigid blade 7 is also pivotally supported, by means of a transverse axis 8, at the lower end of two thin arms 9 fixed to the rear end of the ship under the lower end of the floats, in order to be constantly deeply submerged in water. The rigid blade 7, pivotally mounted on the axis 8, is connected by a transmission not shown to a control device actuable by the pilot, this control device allowing fine adjustment of the incidence of the blade 7 as a function, in particular, the load of the ship, the distribution of this load and the speed of the ship.

Des moyens automatiques pourront également être prévus afin de régler instantanément l'incidence de la lame 7 en fonction des conditions d'évolution du navire.Automatic means may also be provided in order to instantly adjust the incidence of the blade 7 as a function of the conditions of evolution of the ship.

Egalement, le bord arrière de cette lame 7 pourra comporter des volets (non représentés), reliés à des moyens de commande manuels ou automatiques pour le réglage de l'inclinaison du navire en marche, ainsi que de son déjaugeage en fonction de la charge et de la vitesse.Also, the rear edge of this blade 7 may include flaps (not shown), connected to manual or automatic control means for adjusting the inclination of the ship in motion, as well as its planing as a function of the load and of speed.

Les avantages de la construction de ce navi­re résultent du fait que, en marche, la portance du navire est déterminée par trois zones constituées d'une zone arrière formée par la lame 7 et de deux zones avant formées par les parties inférieures 1₁, 2₁ des deux flotteurs 1, 2, situés en avant du décroche­ment 5.The advantages of the construction of this vessel result from the fact that, when in motion, the bearing capacity of the vessel is determined by three zones consisting of a rear zone formed by the blade 7 and two front zones formed by the lower parts 1₁, 2₁ of the two floats 1, 2, located in front of the step 5.

Le navire étant supporté par ces trois zones, présente donc une excellente stabilité et un meilleur rendement.The ship being supported by these three zones, therefore has excellent stability and better performance.

Par ailleurs, la lame 7 immergée à l'arrière du navire, protège efficacement les hélices et les safrans lors de l'échouage et n'occasionne aucune gêne, ni pour les manoeuvres d'accostage, ni, dans le cas d'un bateau de pêche, pour la mise à l'eau du matériel de pêche.Furthermore, the blade 7 immersed at the rear of the ship, effectively protects the propellers and rudders during grounding and does not cause any discomfort, either for docking maneuvers, or, in the case of a boat for the launching of fishing gear.

Le décrochement 5 est situé en avant du cen­tre de gravité du navire et la combinaison du décro­chement 5 et de la lame 7 permet, lors de la marche du navire, de déplacer vers l'avant, en F1, la force de soulèvement du navire, celle-ci se trouvant, à l'arrêt, en F2, à la verticale du centre de gravité P.The recess 5 is located in front of the center of gravity of the ship and the combination of the recess 5 and the blade 7 makes it possible, when the ship is in motion, to move forward, in F1, the lifting force of the ship, this being, at standstill, in F2, vertical to the center of gravity P.

Dans l'exemple représenté, le décrochement 5 forme un angle vif situé en avant du centre de gravité et se prolonge jusqu'au bord arrière 6 suivant une courbe évolutive dont la tangente se trouve sensible­ment parallèle à la surface de l'eau lorsque le navire est en marche.In the example shown, the step 5 forms a sharp angle located in front of the center of gravity and extends to the rear edge 6 along an evolving curve whose tangent is substantially parallel to the surface of the water when the ship is under way.

Egalement, dans l'exemple représenté, la zone inférieure des flotteurs est profilée en V, que ce soit à l'avant ou à l'arrière du décrochement 5. Cependant, toute autre forme de réalisation pourra être choisie en fonction du type du navire réalisé et de son utilisation.Also, in the example shown, the lower zone of the floats is V-shaped, whether at the front or at the rear of the recess 5. However, any other embodiment may be chosen according to the type of the ship. made and its use.
