Abstract
Description
La présente invention a pour objet une embarcation à hautes performancesThe present invention relates to a high performance craft
de vitesse.of speed.
L'embarcation dont il s'agit est une embarcation motorisée. Il existe différents types d'embarcations, notamment des embarcations de type monocoque, et des embarcations multicoques, notamment des embarcations à deux coques appelées catamaran. The boat in question is a motorboat. There are different types of boats, including monohulls, and multihulls, including two-hulled vessels called catamarans.
Les embarcations monocoques motorisées possèdent des performances qui dépendent de la motorisation ainsi que de la longueur de l'embarcation. Ces embarcations, lorsqu'elles sont destinées à des transports de marchandises ou de passagers, sont des embarcations lourdes, avec un tirant d'eau important. Monohull motorized boats have performances that depend on the motorization as well as the length of the boat. These boats, when they are intended for the transport of goods or passengers, are heavy boats, with a large draft.
II existe également des catamarans qui permettent de réduire le tirant d'eau et d'accéder à des ports dans lesquels la profondeur d'eau est peu importante. Si ces catamarans sont bien motorisés, ils peuvent atteindre des vitesses élevées. Toutefois, les efforts qui sont transmis par les coques aux éléments de liaison entre celles-ci, et notamment au pont qui réunit les coques sont très importants. II en résulte un alourdissement de l'embarcation, qui va à l'encontre des performances, et qui nécessite des motorisations particulièrement élevées. There are also catamarans that can reduce the draft and access ports in which the water depth is small. If these catamarans are well motorized, they can reach high speeds. However, the efforts that are transmitted by the hulls to the connecting elements between them, including the bridge that joins the hulls are very important. This results in an increase in the boat, which goes against performance, and which requires particularly high engines.
Le problème technique à la base de l'invention est de réaliser une embarcation pouvant servir au transport de personnes ou de marchandises, qui soit d'un poids réduit, tout en possédant une bonne solidité, et permette des performances de vitesse importantes, en mettant en oeuvre un principe de sustentation de l'embarcation. The technical problem underlying the invention is to make a boat that can be used to transport people or goods, which is of a reduced weight, while having good strength, and allows high speed performance, putting implement a principle of levitation of the boat.
A cet effet, l'embarcation qu'elle concerne est caractérisée en ce qu'elle comprend au moins cinq coques parallèles reliées par un panneau de pont sur au moins une partie de la longueur des coques, en ce que la projection horizontale de la surface mouillée des différentes coques est supérieure ou égale à 1/3 de la projection horizontale de l'embarcation (longueur x largeur) et en ce que le rapport entre la longueur L et la largeur I est tel que: L = 2 à 2,5 I. Cette combinaison de caractéristiques permet la réalisation d'une embarcation qui est à la fois légère et solide, et ne nécessite pas une motorisation importante, dans la mesure où l'air qui s'engouffre dans les tunnels formés entre les différentes coques, assure une sustentation de l'embarcation et réduit la surface mouillée de cette dernière. For this purpose, the boat it concerns is characterized in that it comprises at least five parallel hulls connected by a deck panel over at least a part of the length of the hulls, in that the horizontal projection of the surface wet of the different hulls is greater than or equal to 1/3 of the horizontal projection of the boat (length x width) and in that the ratio between the length L and the width I is such that: L = 2 to 2.5 I. This combination of features allows the realization of a boat that is both light and strong, and does not require a significant motorization, insofar as the air that rushes into the tunnels formed between the different hulls, provides a lift for the boat and reduces the wet surface of the boat.
La motorisation peut être réalisée à l'aide d'un ou de plusieurs moteurs, la motorisation pouvant, par exemple, être répartie en plaçant un moteur dans chaque coque. En fonction de la charge et des conditions de navigation, il est possible ou non d'utiliser simultanément tous les moteurs. The motorization can be carried out using one or more motors, the motorization can, for example, be distributed by placing a motor in each shell. Depending on the load and the navigation conditions, it is possible or not to use all motors simultaneously.
C'est ainsi qu'en phase de démarrage, il est possible d'utiliser plusieurs moteurs puis, lorsque l'embarcation se trouve en position de sustentation, de n'utiliser, par exemple, que deux moteurs qui ne sont pas mis en oeuvre à la puissance maximale. Thus, in the start-up phase, it is possible to use several engines and, when the boat is in the lift position, to use, for example, only two engines that are not implemented. at maximum power.
Suivant la taille de l'embarcation, les coques peuvent être utilisées comme zone de stockage ou comme zone habitable. Cette structure est parfaitement adaptée pour la construction d'embarcation d'une taille pouvant atteindre 50 m de long. Depending on the size of the boat, the hulls can be used as a storage area or as a living area. This structure is perfectly suited for boat construction up to 50 m long.
Suivant une caractéristique avantageuse de l'invention, le rapport entre la longueur L et la largeur I de l'embarcation est tel que: L = 2,33 I. 15 En outre, toutes les coques sont identiques. According to an advantageous characteristic of the invention, the ratio between the length L and the width I of the boat is such that: L = 2.33 I. In addition, all the hulls are identical.
Suivant une caractéristique importante de l'invention, chaque coque comprend un fond plat relié à deux parois verticales, éventuellement par un chanfrein. According to an important characteristic of the invention, each shell comprises a flat bottom connected to two vertical walls, possibly by a chamfer.
Avantageusement, les parois verticales de chaque coque sont planes et forment entre elles un angle compris entre 2 et 3 . Il doit être noté que l'angle formé par les parois verticales de chaque coque étant très faible, ces coques sont très effilées, et offrent peu de résistance dans le passage des vagues, pour ce qui concerne leur partie immergée. Advantageously, the vertical walls of each shell are flat and form between them an angle of between 2 and 3. It should be noted that the angle formed by the vertical walls of each hull being very small, these hulls are very slender, and offer little resistance in the passage of the waves, with regard to their immersed part.
Suivant une autre caractéristique de l'invention, à l'extrémité arrière 25 de l'embarcation, la largeur de chaque coque est sensiblement égale à l'écartement entre deux coques. According to another characteristic of the invention, at the rear end 25 of the boat, the width of each hull is substantially equal to the spacing between two hulls.
Suivant une forme d'exécution de cette embarcation, le fond de chaque coque forme avec l'horizontale un angle 0,5 , incliné de l'avant vers l'arrière et de bas en haut. According to one embodiment of this boat, the bottom of each shell forms with the horizontal an angle 0.5, inclined from front to rear and bottom to top.
En outre, la face inférieure du panneau de pont reliant les coques est sensiblement parallèle au fond des coques. In addition, the underside of the bridge panel connecting the hulls is substantially parallel to the bottom of the hulls.
Suivant une autre caractéristique de l'embarcation, chaque coque comporte, à son extrémité avant, sur une longueur comprise entre 5 et 7,5 % environ de la longueur de la coque, une face inférieure inclinée de bas en haut 35 et de l'arrière vers l'avant, formant avec l'horizontale un angle de l'ordre de 35 . According to another characteristic of the boat, each hull has, at its front end, a length of between 5 and 7.5% of the length of the hull, a lower face inclined from bottom to top and 35 rearward forward, forming with the horizontal an angle of the order of 35.
2871134 3 De toute façon, l'invention sera bien comprise, à l'aide de la description qui suit, en référence au dessin schématique annexé, représentant, à titre d'exemple non limitatif, une forme d'exécution de cette embarcation. In any case, the invention will be better understood, with the aid of the description which follows, with reference to the attached schematic drawing, showing, by way of non-limiting example, an embodiment of this craft.
L'embarcation ainsi réalisée est légère, d'une grande finesse, et d'une construction simple en raison des surfaces développables, et d'une construction peu onéreuse du fait de la simplicité de construction et de la puissance relativement faible des moteurs. Le coût d'exploitation est faible avec des performances élevées, c'est-à-dire une vitesse pouvant dépasser soixante noeuds. The craft thus produced is light, of great finesse, and of simple construction because of the developable surfaces, and inexpensive construction because of the simplicity of construction and the relatively low power of the engines. The operating cost is low with high performance, that is to say a speed that can exceed sixty knots.
Figure 1 en est une vue en perspective. Figure 1 is a perspective view.
Figure 2 est une vue en perspective et à échelle agrandie d'un tronçon de coque. Figure 2 is a perspective view on an enlarged scale of a hull section.
Figure 3 est une vue de dessus des différentes coques constitutives de cette embarcation. Figure 3 is a top view of the various hulls constituting this boat.
Figure 4 est une vue de côté d'une coque. Figure 4 is a side view of a hull.
La figure 1 représente une embarcation 2 comprenant cinq coques identiques, recouvertes par un panneau de pont 4 intégrant des éléments de structure reliant les coques. Dans la forme d'exécution représentée au dessin, le panneau de pont porte une superstructure 5. Figure 1 shows a boat 2 comprising five identical hulls, covered by a bridge panel 4 incorporating structural elements connecting the hulls. In the embodiment shown in the drawing, the deck panel carries a superstructure 5.
Si l'on se reporte à la figure 3, la longueur totale de l'embarcation est désignée par la référence L et la largeur totale par la référence I. La projection horizontale de la surface mouillée des différentes coques 3 est supérieure ou égale à 1/3 de la projection horizontale de l'embarcation (L x l), et le rapport entre la longueur L et la largeur 1 est égale à 2,33. With reference to FIG. 3, the total length of the boat is designated by the reference L and the total width by the reference I. The horizontal projection of the wet surface of the various shells 3 is greater than or equal to 1 / 3 of the horizontal projection of the boat (L xl), and the ratio between the length L and the width 1 is equal to 2.33.
Comme montré à la figure 2, chaque coque 3 comporte un fond plat 6, ainsi que deux parois verticales planes 7, le fond 6 étant relié aux parois 7 par des chanfreins 8. As shown in FIG. 2, each shell 3 comprises a flat bottom 6, as well as two flat vertical walls 7, the bottom 6 being connected to the walls 7 by chamfers 8.
Comme montré à la figure 3, les parois verticales sont planes et forment entre elles un angle A compris entre 2 et 3 . As shown in FIG. 3, the vertical walls are flat and form between them an angle A of between 2 and 3.
A l'extrémité arrière de l'embarcation, la largeur 9 de chaque coque 3 est sensiblement égale à l'écartement 10 entre deux coques voisines. At the rear end of the boat, the width 9 of each hull 3 is substantially equal to the spacing 10 between two adjacent hulls.
II ressort de la figure 4 que le fond 6 de chaque coque forme avec l'horizontal H1 un angle B inférieur ou égal à 0,5 , le fond étant incliné de l'avant vers l'arrière et de bas en haut. La face inférieure du panneau de pont 4 est parallèle au fond 6. It can be seen from FIG. 4 that the bottom 6 of each shell forms with the horizontal H1 an angle B less than or equal to 0.5, the bottom being inclined from front to rear and from bottom to top. The underside of the bridge panel 4 is parallel to the bottom 6.
Comme montré à la figure 4, chaque coque comporte à son extrémité avant et sur une longueur comprise entre 5 et 7,5 % de la longueur de la coque, une face inférieure 12 inclinée de bas en haut et de l'arrière vers l'avant formant avec l'horizontal un angle C de l'ordre de 35 . As shown in Figure 4, each shell has at its front end and a length of between 5 and 7.5% of the length of the shell, a lower face 12 inclined from bottom to top and back to the before forming with the horizontal an angle C of the order of 35.
Les différentes caractéristiques de cette embarcation lui permettent d'être réalisée avec des matériaux légers, par exemple, en aluminium, sans nécessiter des renforts importants, compte tenu des faibles contraintes qui s'exercent sur les coques. La motorisation peut être réalisée par plusieurs moteurs, par exemple un moteur dans chaque coque 3. Les coques 3 peuvent elles-mêmes servir dans leur partie la plus large de chambre de stockage de marchandises. The different characteristics of this boat allow it to be made with lightweight materials, for example, aluminum, without requiring significant reinforcements, given the low constraints on the hulls. The motorization can be achieved by several motors, for example an engine in each hull 3. The hulls 3 can themselves serve in their widest part of the cargo storage chamber.
En fonctionnement, lorsque l'embarcation atteint une certaine vitesse, l'air s'engouffre dans les tunnels délimités entre les coques, et prend appui sous le panneau de pont pour assurer la sustentation de l'embarcation et limiter sa résistance dans l'eau. II est ainsi possible de gagner en vitesse tout en diminuant la puissance des moteurs. In operation, when the boat reaches a certain speed, the air rushes into the tunnels delimited between the hulls, and bears under the deck hatch to ensure the lift of the boat and limit its resistance in the water . It is thus possible to gain speed while decreasing the power of the engines.
II résulte de ce qui précède que l'invention apporte une grande amélioration à la technique existante, en étant utilisée notamment pour les embarcations de moyen tonnage, rendant son application particulièrement intéressante pour du trafic côtier ou d'une île à une autre. It follows from the foregoing that the invention provides a great improvement to the existing technique, being used in particular for medium-tonnage boats, making its application particularly interesting for coastal traffic or from one island to another.
Comme il va de soi, l'invention ne se limite pas à la seule forme d'exécution de cette embarcation décrite ci-dessus à titre d'exemple, elle en embrasse au contraire toutes les variantes de réalisation. It goes without saying that the invention is not limited to the sole embodiment of this craft described above by way of example, it encompasses all variants.
C'est ainsi notamment que cette embarcation pourrait comporter 25 plus de cinq coques, ou ne pas comporter de superstructure, sans que l'on sorte pour autant du cadre de l'invention. This is the way in particular that this boat could comprise more than five hulls, or do not include superstructure, without departing from the scope of the invention.
