^ Dans la forme de réalisation d'une coque selon l'invention qui est représentée aux figures 1 a 4, la carène comprend quatre faces 10, 12, 14, 16 longitudinales, c'est-a-dire qui s'étendent αe 1 ' avant a 1 ' arrière de la coque et qui forment un W^ In the embodiment of a hull according to the invention which is shown in Figures 1 to 4, the hull comprises four longitudinal faces 10, 12, 14, 16, that is to say which extend to 1 'forward to the back of the hull and which form a W
2_ en section transversale.2_ in cross section.
Ces faces sont sensiblement planes et deux a deux symétriques par rapport a des plans verticaux longitudinaux passant par les sommets du W. Plus précisément, une face extérieure 10 et une faceThese faces are substantially flat and two to two symmetrical with respect to longitudinal vertical planes passing through the vertices of the W. More specifically, an outer face 10 and a face
25 médiane 12 adjacente sont symétriques par rapport a un plan vertical longitudinal 18 passant par le sommet d'un V forme par ces faces 10 et 12, les faces médianes 12 et 14 sont symétriques par rapport a un plan vertical longitudinal médian 20, et la face25 adjacent median 12 are symmetrical with respect to a longitudinal vertical plane 18 passing through the top of a V formed by these faces 10 and 12, the median faces 12 and 14 are symmetrical with respect to a median longitudinal vertical plane 20, and the face
30 médiane 14 et l'autre face extérieure 16 sont symétriques par rapport a un plan vertical longitudinal 22 passant par le sommet du V forme par ses faces 14 et 16. Dans l'exemple des figures 1 a 4, l'angle des faces 10, 12, 14, 16 avec la verticale30 median 14 and the other outer face 16 are symmetrical with respect to a longitudinal vertical plane 22 passing through the top of the V formed by its faces 14 and 16. In the example of FIGS. 1 to 4, the angle of the faces 10 , 12, 14, 16 with the vertical
3" est d'environ 45°. De façon générale, il peut être compris entre 40 et "5° environ. Dans un mode αe réalisation actuellement préfère, cet angie est compris entre 55 et 70° environ et de façon encore plus préfère, est voisin de 63°. 5 Les faces médianes 12 et 14 forment un tunnel central en V inverse dont le sommet 24 est sensiblement au niveau de la ligne de flottaison 26 et s'étend iongitudmalement au niveau de cette ligne de flottaison de la poupe jusqu'au voisinage de la3 "is about 45 °. Generally speaking, it can be between 40 and " 5 ° approximately. In an embodiment currently preferred, this angia is between 55 and 70 ° approximately and even more preferably, is close to 63 °. 5 The median faces 12 and 14 form a tunnel central in reverse V whose apex 24 is substantially at the level of the waterline 26 and extends iongitudmalement at the level of this waterline of the stern to the vicinity of the
J.C proue 28 ou elle remonte vers le haut.J.C prow 28 or it goes up.
La proue 28 est tronquée transversalement, de sorte que le tunnel central forme par les faces 12 et 14 deoute a la partie la plus avant de la coque, les faces 12 et 14 conservant un même angle sur la quasi- i totalité de la longueur de la coque et s ' évasant légèrement au voisinage immédiat de la proue.The bow 28 is truncated transversely, so that the central tunnel forms by the faces 12 and 14 facing the most forward part of the hull, the faces 12 and 14 retaining the same angle over almost the entire length of the hull and slightly flaring in the immediate vicinity of the bow.
La coque peut comprendre, comme représente scheπatiquement , un redan extérieur 30 qui s'étend de la poupe jusqu'au voisinage de la proue mais sans " aller jusqu'à celle-ci. Cette dernière peut alors prendre une forme légèrement ovoïde pour une habilite maximale .The hull may include, as shown schematically, an outer step 30 which extends from the stern to the vicinity of the bow but without "going to the latter. The latter can then take a slightly ovoid shape for a skill maximum.
Des virures 32, de forme saillante, comme représente en figure 1, ou rentrante (figure 5),Strakes 32, projecting, as shown in FIG. 1, or re-entrant (FIG. 5),
25 peuvent également être formées sur les faces extérieures 10 et 16, ainsi que sur les faces médianes 12 et 14, et s'étendre de la poupe jusqu'au voisinage de l' extrémité avant du redan extérieur 30. En variante, le redan extérieur 30 et les virures 3225 can also be formed on the outer faces 10 and 16, as well as on the median faces 12 and 14, and extend from the stern to the vicinity of the front end of the outer step 30. As a variant, the outer step 30 and strakes 32
30 peuvent s'étendre jusqu'au voisinage immédiat de la proue 28.30 can extend to the immediate vicinity of bow 28.
La carène selon l'invention a une surface portante qui est supérieure a celle d'une coque en V qui aurait le même tirant d'eau et la même largeur.The hull according to the invention has a bearing surface which is greater than that of a V-shaped hull which would have the same draft and the same width.
"5 Cette augmentation est de l'ordre de 25 - quand ±e tirant d'eau est sensiblement égal a la moitié de la largeur de la coque. " 5 This increase is of the order of 25 - when ± e draft is substantially equal to half the width of the hull.
Dans la variante de réalisation des figures 6 a 9, la carène a toujours une forme de W en section 5 transversale, mais les faces extérieures 10 et 16 ne sont plus symétriques des faces médianes 12 et 14 par rapport aux plans verticaux longitudinaux 18 et 22 respectivement, les faces médianes 12 a 14 restant toutefois symétriques l'une de l'autre par rapport au plan vertical longitudinal médian 20. Dans l'exemple représente, les angles des faces médianes 14, 16 avec la verticale sont inférieurs aux angles des faces extérieures 10, 16 avec la verticale.In the alternative embodiment of FIGS. 6 to 9, the hull always has a W shape in cross section, but the outer faces 10 and 16 are no longer symmetrical with the middle faces 12 and 14 with respect to the longitudinal vertical planes 18 and 22 respectively, the median faces 12 to 14 however remaining symmetrical to each other with respect to the median longitudinal vertical plane 20. In the example shown, the angles of the median faces 14, 16 with the vertical are less than the angles of the faces 10, 16 with the vertical.
La ligne de fond 24 du tunnel forme par lesThe bottom line 24 of the tunnel formed by the
±5 faces médianes 12 et 14 est sensiblement rectiligne et au niveau de la ligne de flottaison 26, mais est légèrement inclinée vers le bas par rapport a l'horizontale de la proue vers la poupe. Cela a pour conséquence d'augmenter légèrement l'angle entre les± 5 median faces 12 and 14 is substantially rectilinear and at the level of the waterline 26, but is slightly inclined downward relative to the horizontal of the bow towards the stern. This has the effect of slightly increasing the angle between the
20 deux faces 12 et 14 a l'arriére de la coque. On augmente ainsi la portance de la coque sur l'arriére pour mieux maintenir la coque a l'horizontale er déplacement .20 two faces 12 and 14 at the rear of the hull. This increases the lift of the hull on the back to better maintain the hull horizontal and displacement.
Comme dans le mode de réalisation précèdent, desAs in the previous embodiment,
25 redans extérieurs 30 peuvent être formes sur les faces extérieures 10, 16 de la carène et s'étendre de la poupe jusqu'au voisinage de la proue, ou Dier s'étendre jusqu'à la proue. De même, des virures 32 peuvent être formées sur les faces extérieures 10 et25 external steps 30 can be formed on the external faces 10, 16 of the hull and extend from the stern to the vicinity of the bow, or Dier extend to the bow. Likewise, strakes 32 can be formed on the outer faces 10 and
30 16 ainsi qu'éventuellement sur les faces médianes 12 et 14 de la carène.30 16 as well as possibly on the median faces 12 and 14 of the hull.
Dans la variante de réalisation des figures 10 et 11, qui correspond au mode de réalisation des figures 1 a 4, les deux faces médianes 14 et 16 de laIn the alternative embodiment of FIGS. 10 and 11, which corresponds to the embodiment of FIGS. 1 to 4, the two middle faces 14 and 16 of the
3 - carene sont reunies entre e^les, a l'arriére de la coque, par un aileron transversal 34 de type hydrofoil, qui est immergé et dont le profil incurvé a une concavité tournée vers le bas, pour augmenter la portance à l'arrière de la coque et compenser au moins en partie le poids des moteurs. Cet aileron peut être monté de façon amovible entre les faces 14, 16 de la carène.3 - carene are reunited between them, at the back of the hull, by a transverse fin 34 of hydrofoil type, which is immersed and whose curved profile has a concavity turned downwards, to increase the lift at the rear of the hull and at least partially compensate for the weight of the engines. This fin can be removably mounted between the faces 14, 16 of the hull.
De façon générale, une coque selon l'invention présente les avantages suivants, en plus de ceux déjà mentionnés de plus grande stabilité, d'augmentation de l'habitabilité et d'échouage en position horizontale stable :In general, a hull according to the invention has the following advantages, in addition to those already mentioned of greater stability, increased habitability and grounding in a stable horizontal position:
- à l'arrêt, le bateau est plus stable du fait de l'absence de couple de roulis, - en déplacement, en raison de la pression de l'eau exercée sur chacune des quatre faces de la carène en W, la coque sort plus facilement de l'eau à 1 ' avant,- when stationary, the boat is more stable due to the lack of rolling torque, - when moving, due to the pressure of the water exerted on each of the four sides of the hull in W, the hull comes out water more easily at the front,
- la portance est augmentée à 1 ' arrière par les caractéristiques représentées dans les figures 5 à 10 et le bateau se déplace en restant sensiblement horizontal,- the lift is increased at the rear by the characteristics shown in FIGS. 5 to 10 and the boat moves while remaining substantially horizontal,
- le bateau vire à plat. - the boat turns flat.
