Description

La présente invention est relative à une embarca­tion d'assaut.The present invention relates to an assault craft.

Les embarcations d'assaut connues jusqu'à présent sont du type péniche ayant à l'avant une rampe articulée autour d'un axe horizontal pour pouvoir s'abaisser et se relever et s'étendant sur à peu près toute la largeur de l'embarcation, qui présente une section transversale de forme en U sur à peu près la totalité de sa longueur.The assault boats known up to now are of the barge type having at the front a ramp articulated around a horizontal axis to be able to lower and raise and extending over almost the entire width of the boat, which has a U-shaped cross section over almost its entire length.

Cette forme a été adoptée afin de disposer à l'intérieur de l'embarcation d'un espace dégagé maximum pour la troupe et/ou le matériel à transporter.This form was adopted in order to have inside the boat a maximum clear space for the troop and / or the material to be transported.

Cette conception présente des inconvénients, d'une part en ce qui concerne la rigidité, car une telle forme de coque en U non pontée est facilement déformable en torsion et d'autre part en raison des qualités marines très médio­cres de ces formes de coques.This design has drawbacks, on the one hand as regards rigidity, since such a shape of an unbridged U-shaped hull is easily deformable in torsion and on the other hand due to the very poor marine qualities of these hull shapes.

En outre la machinerie et la timonerie se trouvent obligatoirement reléguées à l'extrémité arrière. Ceci ne présente pas d'inconvénient en ce qui concerne la machine, mais est par contre beaucoup plus gênant en ce qui concerne la timonerie, car toute la longueur et la largeur de l'em­barcation nécessairement haute de l'avant masquent la vue à l'homme de barre, gênant ainsi considérablement la manoeuvre.In addition the machinery and the wheelhouse are necessarily relegated to the rear end. This does not have any drawback with regard to the machine, but is on the other hand much more annoying with regard to the wheelhouse, because the entire length and width of the boat necessarily high from the front obscure the view to the helmsman, considerably hampering the maneuver.

Enfin, le seul emplacement disponible pour l'arme­ment de l'embarcation est également situé au même endroit, à l'arrière, ce qui limite non seulement sa puissance en raison du manque d'espace et de la proximité de la timone­rie, mais également son efficacité.Finally, the only place available for the cocking of the boat is also located in the same place, aft, which limits not only its power due to the lack of space and the proximity of the wheelhouse, but also its efficiency.

Il est en effet nécessaire de pouvoir couvrir le débarquement, par exemple d'un commando, ou la mise à terre d'un matériel, par un appui-feu le plus efficace possible, qui ne peut être assuré par une pièce située à l'arrière, dont le champ de tir est réduit et pour laquelle la zone de plageage est masquée.It is indeed necessary to be able to cover the landing, for example of a commando, or the grounding of a material, by a fire support as efficient as possible, which cannot be ensured by a part located at the rear, whose range is reduced and for which the range is hidden.

L'invention a pour but de remédier à ces inconvé­nients en réalisant une embarcation d'assaut polyvalente ayant d'excellentes qualités marines, pouvant également se déplacer sur des plans d'eau difficiles, et constituant également une excellente plate-forme de tir.The object of the invention is to remedy these drawbacks by producing a multi-purpose assault boat having excellent marine qualities, which can also be move on difficult water bodies, and also constitute an excellent shooting platform.

Elle a pour objet à cet effet une embarcation d'assaut à rampe avant relevable caractérisée en ce qu'elle est du type catamaran, comportant deux coques espacées reliées par un plancher, et en ce que ladite rampe releva­ble est constituée par une partie avant dudit plancher comprise entre les deux coques.It has for this purpose an assault boat with a lifting front ramp characterized in that it is of the catamaran type, comprising two spaced hulls connected by a floor, and in that said lifting ramp is constituted by a front part of said floor between the two hulls.

Suivant une autre caractéristique de l'invention, chaque coque comporte un pontage avant adapté pour recevoir une ou plusieurs armes automatiques ou une pièce d'artille­rie légère.According to another characteristic of the invention, each hull has a front deck adapted to receive one or more automatic weapons or a light artillery piece.

En se référant au dessin, l'embarcation d'assaut suivant l'invention est du type multicoques "catamaran" comportant deux coques parallèles espacées 1 et 2 réunies par un plancher, ou pont 3 s'étendant d'un même niveau du côté babord de la coque babord 1 au côté tribord de la coque tribord 2, fournissant ainsi une surface utile de chargement qui représente la surface totale, en plan de l'embarcation, à l'exception de la seule partie du plancher située entre les étraves des deux coques, qui constitue la rampe mobile 4 de l'embarcation.Referring to the drawing, the assault boat according to the invention is of the multihull type "catamaran" comprising two spaced parallel hulls 1 and 2 joined by a floor, or deck 3 extending at the same level on the port side. from the port hull 1 to the starboard side of the starboard hull 2, thus providing a useful loading surface which represents the total surface, in plan of the boat, with the exception of the only part of the floor located between the bows of the two hulls, which constitutes the mobile ramp 4 of the boat.

La rampe mobile 4 est articulée autour d'un axe horizontal transversal 5 et est formée par la partie avant du pont 3 située entre la ligne d'étrave 6 et la partie où les coques atteignent la plus grande largeur hors-tout de l'embarcation (maitre-bau).The mobile ramp 4 is articulated around a transverse horizontal axis 5 and is formed by the front part deck 3 located between the bow line 6 and the part where the hulls reach the greatest overall width of the boat (master beam).

La partie du pontage avant de chaque coque 1, 2, sur une longueur à peu près égale à celle de la rampe mobile 4, est renforcée comme représenté en 7 (figure 2) pour recevoir un affût d'une pièce d'artillerie légère 8, ou autre arme automatique.The part of the front deck of each hull 1, 2, over a length approximately equal to that of the mobile ramp 4, is reinforced as shown in 7 (FIG. 2) to receive a mount for a light artillery piece 8 , or other automatic weapon.

D'une façon avantageuse un abri de navigation 9 est aménagé, par exemple sur la coque tribord, sur un plan­cher surélevé 10 au-dessus du plancher 3 de charge, immédia­tement en arrière de la pièce 8, dégageant ainsi un champ de vision panoramique très étendu.Advantageously, a navigation shelter 9 is arranged, for example on the starboard hull, on a raised floor 10 above the load floor 3, immediately aft of the room 8, thus freeing up a very wide panoramic field of vision. extended.

Un compartiment moteur 11 est également aménagé à l'arrière de chaque coque, l'embarcation étant de préférence propulsée par un dispositif à réaction de fluide du type "hydrojet" 12 permettant à l'embarcation de circuler même dans les marécages.An engine compartment 11 is also arranged at the rear of each hull, the boat being preferably propelled by a fluid reaction device of the "hydrojet" type 12 allowing the boat to circulate even in swamps.

On comprend bien entendu que l'invention n'est pas limitée à ce mode de propulsion, et que la machine motrice de l'embarcation peut être d'un type quelconque.It will of course be understood that the invention is not limited to this mode of propulsion, and that the engine of the boat can be of any type.

Les volumes des coques 1 et 2 peuvent être utili­sés suivant les besoins des missions, soit comme soutes, soit comme logement pour l'équipage et/ou les passagers comme représenté en 13.The volumes of hulls 1 and 2 can be used according to the needs of the missions, either as bunkers or as accommodation for the crew and / or passengers as shown in 13.

La partie arrière du pont S est par exemple cou­verte par une plate-forme 14 renforcée pour permettre le transport et/ou l'atterissage d'un hélicoptère 15, tout en ménageant au-dessous une hauteur suffisante pour loger des camions 16.The rear part of the bridge S is for example covered by a reinforced platform 14 to allow the transport and / or the landing of a helicopter 15, while leaving below a height sufficient to accommodate trucks 16.

De préférence, il est prévu des quilles d'échouage 17 sous les deux coques.Preferably, grounding pins 17 are provided under the two shells.

La figure 6 montre un exemple d'un système de relevage 18 pour la rampe 4, qui comprend un petit treuil (par exemple électrique) 19enroulant ou déroulant sur son tambour une chaîne 20 dont une extrémité est frappée sur un angle avant de la rampe mobile 4. Un treuil 19 est prévu sur l'avant de chaque coque 1, 2.FIG. 6 shows an example of a lifting system 18 for the ramp 4, which comprises a small winch (for example electric) 19winding or unwinding on its drum a chain 20, one end of which is struck on a front angle of the mobile ramp 4. A winch 19 is provided on the front of each hull 1, 2.

L'embarcation d'assaut suivant l'invention est apte à circuler dans les eaux peu profondes, en mer comme en rivière, comme en eaux profondes en raison de son faible tirant d'eau et de sa stabilité intrinsèque et de ses qualités marines, ainsi même que dans les marais grâce à un système propulseur sans hélices.The assault boat according to the invention is able to circulate in shallow waters, at sea and in rivers, as well as in deep waters due to its shallow draft and its intrinsic stability and its marine qualities, as well as in marshes thanks to a propellant system without propellers.
