Description

Système de mise à l'eau et de récupération d'engin marin et sous-marin assisté par des protections inclinables  Launching and recovery system for marine and submarine equipment assisted by tilting protections
La présente invention se situe dans le domaine naval et concerne un système de mise à l'eau et de récupération d'engin marin ou sous-marin (L.A.R.S., pour « Launch And Recovery System >>) capable, d'une part de soulever l'engin depuis l'eau jusqu'à un système de remorquage embarqué à un navire porteur, et d'autre part de descendre l'engin du navire porteur jusqu'à la mer. Elle s'applique notamment à la mise à l'eau d'engins sous- marins remorqués ou autonomes, ces derniers étant alors munis d'un lien temporaire pendant les phases de mise à l'eau et de récupération. The present invention is in the naval field and relates to a system for launching and recovering marine or underwater craft (LARS, for "Launch And Recovery System") capable, on the one hand to lift the craft from the water to a towing system onboard a carrier, and on the other hand down the craft of the carrier ship to the sea. It applies in particular to the setting underwater gear towed or autonomous, the latter being then provided with a temporary link during the launching and recovery phases.
Les opérations de mise à l'eau et de récupération d'un engin marin ou sous-marin depuis un navire porteur, chargé par ailleurs du transport de cet engin, comporte généralement une phase critique, surtout par mer agitée. Cette phase consiste dans le passage de l'état totalement émergé où l'engin est solidaire des moyens de manutention utilisés, à l'état totalement immergé où l'engin n'a plus de lien avec ceux-ci, et inversement. En effet, c'est durant ces phases critiques que les mouvements de houle sont les plus dangereux pour l'intégrité de l'engin, celui-ci étant secoué par la houle alors qu'il se trouve à proximité soit de la structure du navire, soit de celle des moyens de levage et de manutention, au risque de les heurter. C'est en particulier le cas pour un engin marin ou sous-marin dans la phase de mise à l'eau ou de récupération, lorsque l'engin est partiellement dans l'eau : ses mouvements ne sont pas encore (ou ne sont plus) complètement maîtrisés par les moyens de levage et de manutention. The launching and recovery operations of a marine or submarine craft from a carrier vessel, which is otherwise responsible for the transport of this craft, generally involves a critical phase, especially in rough seas. This phase consists of the passage of the fully emerged state where the craft is secured to the handling means used, in the fully submerged state where the craft no longer has any link with them, and vice versa. Indeed, it is during these critical phases that the swell movements are the most dangerous for the integrity of the craft, it being shaken by the swell while it is close to the ship structure or that of the lifting and handling means, at the risk of hitting them. This is particularly the case for a marine or submarine gear in the launching or recovery phase, when the gear is partially in the water: its movements are not yet (or no longer ) completely controlled by lifting and handling equipment.
Ainsi, en ce qui concerne les engins autonomes, non tractés par le navire, une solution connue consiste à prévoir des moyens d'arrimage sur la coque de l'engin, par exemple des anneaux de fixation, ces moyens de fixation étant agencés de telle façon que l'engin puisse être levé en gardant une position horizontale. La mise à l'eau et la récupération peut alors, par exemple, être réalisée au moyen d'un treuil monté sur un portique mobile placé à l'arrière du navire, ou encore une grue, le portique ou la grue permettant de positionner le treuil de levage au dessus de la zone de récupération. Par suite la mise à l'eau et la remontée s'effectuent à la verticale ce qui limite les possibilités de collision avec le navire pendant la descente ou la remontée. Alternativement le levage de l'engin peut être réalisé en plaçant celui-ci dans un dispositif de type nacelle comportant lui- même des points de fixation appropriés. Thus, with respect to autonomous gear, not towed by the ship, a known solution is to provide means of lashing on the hull of the machine, for example fixing rings, these fixing means being arranged in such a way that the machine can be lifted while keeping a horizontal position. The launching and the recovery can then, for example, be carried out by means of a winch mounted on a movable gantry placed at the rear of the ship, or a crane, the crane or the crane allowing to position the hoist winch above the recovery area. As a result, the launch and the lift are carried out vertically which limits the possibilities of collision with the ship during the descent or ascent. Alternatively the lifting of the machine can be achieved by placing it in a nacelle-type device itself having appropriate fixing points.
Ce type de solution est applicable, notamment de manière autonome, à des engins remorqués par le milieu mais n'est cependant pas facilement applicable au cas des engins remorqués par l'avant, dans la mesure où, pour des raisons évidentes d'efficacité, on souhaite réaliser le tractage et la manutention de l'engin à partir d'un câble unique. Une manutention par des moyens tels que ceux décrits précédemment en utilisant un câble unique s'avère délicate car elle entraîne pour l'engin un passage de la position verticale à la position horizontale lors de la mise à l'eau et inversement lors de la récupération. Cette manutention nécessite en outre des opérations complémentaires qui ont pour objet, après levage de l'engin et positionnement au dessus du pont du navire, de reposer l'engin à plat sur le pont du navire ou plus généralement sur une aire de stockage. Ces opérations nécessitent généralement l'intervention d'opérateurs humains, intervention qui est rendue plus délicate et plus dangereuse par mer forte. Lors de l'utilisation d'engins remorqués par l'avant, la solution généralement préférée consiste à utiliser un câble de manutention accroché temporairement au-dessus du centre de gravité de l'engin. Une solution également utilisée prévoit une manutention basée sur la mise en place de moyens comportant une rampe inclinée sur laquelle glisse l'engin pour rejoindre la surface de l'eau ou pour en sortir et retourner sur le navire. La rampe est généralement configurée de façon à assurer le guidage de l'engin selon une trajectoire rectiligne, ce qui évite que l'engin puisse suivre un déplacement latéral. Cependant, une telle rampe n'est généralement pas adaptée à un usage par forte mer : des déplacements latéraux de l'engin peuvent alors l'endommager. L'utilisation de tels moyens permet avantageusement de réaliser la mise à la mer et le déploiement de l'engin derrière le navire en laissant filer le câble de remorquage et, inversement, de récupérer l'engin à bord du navire en enroulant le câble, sur le tambour d'un treuil par exemple. De cette manière, la mise à l'eau et la récupération de l'engin peuvent être réalisées alors que le navire est en mouvement, de sorte que l'engin, traîné par le navire se positionne naturellement dans l'axe de progression de celui-ci. This type of solution is applicable, notably independently, to gear towed by the medium but is however not easily applicable to the case of gear towed from the front, insofar as, for obvious reasons of efficiency, it is desired to perform the towing and handling of the machine from a single cable. Handling by means such as those described above using a single cable proves tricky because it causes the machine a passage from the vertical position to the horizontal position during launching and vice versa during recovery . This handling also requires additional operations whose object is, after lifting the machine and positioning above the deck of the ship, to rest the craft flat on the deck of the ship or more generally on a storage area. These operations generally require the intervention of human operators, intervention which is made more delicate and more dangerous by strong sea. When using towed equipment from the front, the generally preferred solution is to use a handling cable temporarily hung above the center of gravity of the machine. A solution also used provides a handling based on the establishment of means having an inclined ramp on which the machine slides to reach the surface of the water or to get out and return to the ship. The ramp is generally configured so as to guide the machine in a rectilinear path, which prevents the machine can follow a lateral movement. However, such a ramp is generally not suitable for use by heavy seas: lateral movements of the machine can then damage it. The use of such means advantageously allows the launching and deployment of the craft behind the ship by letting the towing cable spin and, conversely, recover the craft aboard the ship by winding the cable, on the drum of a winch for example. In this way, the launching and recovery of the craft can be carried out while the ship is moving, so that the craft, dragged by the ship is positioned naturally in the axis of progression of that -this.
Pour pallier ces difficultés d'entrée en contact, diverses solutions ont été développées, solutions généralement adaptées à un type d'engin donné. Ces solutions connues consistent généralement à renforcer la structure de l'engin, principalement le nez, de façon à ce que celui-ci résiste aux chocs consécutifs à l'entrée en contact avec l'extrémité de la rampe. Elle consiste également à mettre en œuvre des moyens permettant de minimiser ces chocs, en particulier en configurant la rampe de façon à ce que son extrémité se trouve située sous la surface de l'eau de telle sorte que l'engin flottant en surface entre en contact avec la surface inclinée de la rampe et non avec son extrémité. De telles solutions s'avèrent néanmoins insuffisantes par mer forte car l'effet de tossage (ou de "slamming" selon la dénomination anglo-saxonne) dû aux vagues est alors renforcé par le mouvement du navire. D'autres solutions ont été développées (par exemple EP 201 10793422 et US 8430049B1 ) dans lesquelles une rampe articulée inclinable est intégrée au navire. L'inclinaison de la rampe permet de contrôler la partie immergée de la rampe. Une fois la rampe immergée, une traction de l'engin permet de franchir la butée qui sépare la rampe de la surface de l'eau. De plus, par forte mer, la rampe peut être émergée. To overcome these difficulties of contact, various solutions have been developed, solutions generally adapted to a given type of gear. These known solutions generally consist in reinforcing the structure of the machine, mainly the nose, so that it is resistant to shocks resulting from coming into contact with the end of the ramp. It also consists in implementing means for minimizing these shocks, in particular by configuring the ramp so that its end is located below the surface of the water so that the floating craft on the surface enters contact with the inclined surface of the ramp and not with its end. Such solutions are nevertheless insufficient in strong sea because the effect of slamming (or "slamming" according to the Anglo-Saxon name) due to the waves is then reinforced by the movement of the ship. Other solutions have been developed (for example EP 201 10793422 and US 8430049B1) in which an articulated ramp inclinable is integrated into the ship. The slope of the ramp controls the submerged part of the ramp. Once the ramp submerged, a traction of the machine makes it possible to cross the stop that separates the ramp from the surface of the water. Moreover, by high sea, the ramp can be emerged.
La solution précédente est efficace mais ne peut pas équiper tous les navires. En effet, beaucoup de navires ne peuvent pas supporter la masse nécessaire à l'installation de l'équipement lié au fonctionnement d'une rampe inclinable articulée. Le problème résolu par la présente invention est de faire franchir à l'engin marin ou sous-marin une marche située entre l'extrémité de la rampe et l'eau, notamment lors de l'utilisation d'un petit navire, par exemple d'une longueur inférieure à 50 mètres et préférentiellement inférieure à 20 mètres, incapable de supporter l'installation d'un équipement trop lourd, tel qu'une rampe inclinable articulée comme décrit dans l'art antérieur. The previous solution is effective but can not equip all ships. Indeed, many ships can not support the mass required for the installation of equipment related to the operation of an articulated tilting ramp. The problem solved by the present invention is to move the marine or underwater craft a step located between the end of the ramp and the water, especially when using a small vessel, for example a length less than 50 meters and preferably less than 20 meters, unable to withstand the installation of too heavy equipment, such as an articulated tilt ramp as described in the prior art.

La description suivante présente plusieurs exemples de réalisation du dispositif de l'invention : ces exemples ne sont pas limitatifs de la portée de l'invention. Ces exemples de réalisation présentent à la fois les caractéristiques essentielles de l'invention ainsi que des caractéristiques additionnelles liées aux modes de réalisation considérés. Par souci de clarté, les mêmes éléments porteront les mêmes repères dans les différentes figures. The following description presents several embodiments of the device of the invention: these examples are not limiting to the scope of the invention. These exemplary embodiments have both the essential characteristics of the invention as well as additional features related to the embodiments considered. For the sake of clarity, the same elements will bear the same references in the different figures.
Dans la suite du texte, les termes avant, arrière, devant et derrière sont définis par rapport à l'axe longitudinal du navire 6 orienté de l'arrière vers l'avant du navire 6. In the rest of the text, the terms front, rear, front and rear are defined with respect to the longitudinal axis of the ship 6 oriented from the rear to the front of the ship 6.
La figure 1 présente une vue schématique de perspective du dispositif de mise à l'eau et de récupération 1 . Ce dispositif est composé de deux éléments : le chariot 2 et l'élément de protection 5, lui-même composé de deux parties solidaires, la partie protectrice 4 et le bras 3. Dans l'exemple de la figure 1 , les deux éléments de protection 5 sont installés de part et d'autre du chariot 2 et sont solidaires entre eux. Ils peuvent pivoter autour du chariot selon l'axe y représenté. Cet axe y est parallèle à la surface de l'eau 25 quand le dispositif est fixé à un navire porteur comme décrit ultérieurement, afin de pouvoir soulever ou déposer l'engin marin ou sous- marin 7 porté par les parties protectrices 4, de préférence possédant une partie courbe pour empêcher le mouvement en avant ou en arrière de l'engin marin ou sous-marin 7 pendant la manœuvre. Le chariot 2 comporte, dans un mode de réalisation particulier, une partie qui a la fonction d'un chaumard 26. FIG. 1 presents a schematic perspective view of the launching and recovery device 1. This device is composed of two elements: the carriage 2 and the protection element 5, itself composed of two integral parts, the protective part 4 and the arm 3. In the example of FIG. protection 5 are installed on either side of the carriage 2 and are integral with each other. They can rotate around the carriage along the y axis shown. This axis is parallel to the surface of the water 25 when the device is attached to a carrier vessel as described later, in order to be able to lift or deposit the marine or underwater vehicle 7 carried by the protective parts 4, preferably having a curved portion to prevent forward or backward movement of the marine or underwater craft 7 during the maneuver. The carriage 2 comprises, in a particular embodiment, a part which has the function of a fairlead 26.
La figure 2 présente une vue schématique de profil d'un exemple de réalisation d'une partie protectrice 4. La forme de cette réalisation est en partie courbe. Une de ses fonctions est de porter l'engin marin ou sous-marin 7 en limitant ou en empêchant les mouvements de l'engin 7 dus à des contraintes extérieures, vers l'avant, de cavalement, d'embardée, de pilonnement, de roulis et de lacet. Dans une réalisation particulière de l'invention, l'arrière de la partie protectrice 4 présente une partie évidée. Cette configuration peut être particulièrement utile dans le cas d'un contact entre la partie protectrice 4 et une aile 12 d'engin marin ou sous-marin 7. L'arrière de l'aile 22, dit bord de fuite, est plus fin et possède une résistance mécanique plus faible que la partie avant 23 : le contact peut, dans cette réalisation, avoir lieu uniquement sur la surface de la partie la plus résistante mécaniquement de l'aile 12. Figure 2 shows a schematic side view of an embodiment of a protective portion 4. The form of this embodiment is partly curved. One of its functions is to carry the marine or submarine machine 7 by limiting or preventing the movements of the machine 7 due to external constraints, forwards, cavally, yawning, heaving, roll and yaw. In a particular embodiment of the invention, the rear of the protective portion 4 has a recessed portion. This configuration can be particularly useful in the case of a contact between the protective part 4 and a wing 12 of marine or underwater vehicle 7. The rear of the wing 22, said trailing edge, is thinner and has a lower mechanical strength than the front part 23: the contact can, in this embodiment, take place only on the surface of the strongest part mechanically of the wing 12.
La figure 3 présente une vue de profil d'une réalisation de l'ensemble du système L.A.R.S. lors d'une phase de mise à l'eau ou de récupération d'un engin marin ou sous-marin 7. Dans cette réalisation, la position de l'élément de protection 5 est déterminée par trois facteurs : FIG. 3 presents a profile view of an embodiment of the entire L.A.R.S. during a launching phase or recovery of a marine or underwater vehicle 7. In this embodiment, the position of the protection element 5 is determined by three factors:
- la liaison pivot avec le chariot 2, décrite précédemment, the pivot connection with the carriage 2, described above,
- la différence entre la force de gravité et la poussée d'Archimède subie par l'élément de protection 5 : l'élément de protection 5 est, dans cette réalisation particulière, dit de type pesant car il ne flotte pas, et  the difference between the force of gravity and the buoyancy force experienced by the protection element 5: the protection element 5 is, in this particular embodiment, said to be heavy because it does not float, and
- le contact avec l'aile 12 de l'engin marin ou sous-marin 7 qui s'appuie sur l'élément de protection 5.  - The contact with the wing 12 of the marine or underwater vehicle 7 which is based on the protective element 5.
Dans cette configuration, on qualifiera la liaison pivot liant un des éléments de protection 5 et le chariot 2 de libre en rotation. Bien que la rotation puisse être contrainte par un des trois facteurs précédents, cette qualification est aussi faite pour différencier ce mode de réalisation d'un mode de réalisation particulier dans lequel la position d'un élément de protection 5 peut être déterminée de manière prépondérante par un couple moteur appliqué par un premier moyen moteur, à l'élément de protection 5 par la liaison pivot liée au chariot 2. Dans une réalisation particulière de l'invention, un élément de protection flottant peut par exemple être couplé à un premier moyen moteur pour contrôler l'immersion de l'élément de protection flottant. Le chariot 2 se situe dans la figure 3 en bas de la rampe 1 1 , en position basse ou reculée, à laquelle il est lié par une liaison glissière. En phase de mise à l'eau ou de remontée de l'engin marin ou sous-marin 7, l'extrémité avant de l'engin 7 est solidaire du câble de traction 1 6. Ce câble de traction 16 est inséré à l'intérieur du chaumard 26 du chariot 2 et reste en contact étroit avec celui-ci, ce qui a pour effet avantageux de maintenir l'axe de l'engin 7 dans l'axe de la rampe 1 1 pendant la progression le long de cette dernière. In this configuration, it will qualify the pivot link binding one of the protection elements 5 and the carriage 2 of free rotation. Although the rotation can be constrained by one of the three preceding factors, this qualification is also made to differentiate this embodiment of a particular embodiment in which the position of a protection element 5 can be determined predominantly by a motor torque applied by a first motor means, to the protection element 5 by the pivot connection connected to the carriage 2. In a particular embodiment of the invention, a floating protection element may for example be coupled to a first motor means to control the immersion of the floating protection element. The carriage 2 is located in Figure 3 at the bottom of the ramp 1 1, in the low or back position, to which it is connected by a slide connection. In the launching or raising phase of the marine or submarine machine 7, the front end of the machine 7 is secured to the traction cable 1 6. This traction cable 16 is inserted into the inside the fairlead 26 of the carriage 2 and remains in close contact therewith, which has the advantageous effect of keeping the axis of the machine 7 in the axis of the ramp 1 1 during the progression along the latter .
Ce maintien en contact est naturellement obtenu dans la mesure où le chariot 2 est un élément massif dont le poids, en l'absence d'engin marin ou sous-marin 7, tend à le faire descendre le long de la rampe 1 1 . Lors d'une mise à l'eau, le chariot 2 accompagne ainsi la progression de l'engin marin ou sous-marin 7. Dans une réalisation particulière de l'invention, le chariot 2 comporte un second moyen moteur qui lui permet de forcer la descente le long de la rampe 1 1 pour rester en contact avec l'engin marin ou sous-marin 7 lors de sa récupération ou de sa mise à l'eau.  This keeping in contact is naturally obtained to the extent that the carriage 2 is a massive element whose weight, in the absence of marine or underwater vehicle 7, tends to make it descend along the ramp 1 1. When launching, the carriage 2 thus accompanies the progression of the marine or underwater vehicle 7. In a particular embodiment of the invention, the carriage 2 comprises a second motor means which enables it to force the descent along the ramp 1 1 to stay in contact with the marine or submarine 7 when recovering or launching.
La monté ou la descente de l'engin marin ou sous-marin 7 est assurée par un moyen de traction 14 composé du câble de traction 1 6, solidaire de l'engin marin ou sous-marin 7, et d'un treuil 15, solidaire du navire porteur 6, qui permet de tracter le câble 1 6 lors d'une phase de récupération, ou de relâcher le câble 1 6 lors d'une phase de mise à l'eau, grâce à un troisième moyen moteur 20 capable d'imposer un second couple moteur au treuil 15. Dans un mode de réalisation particulier, l'engin marin ou sous-marin 7 peut être un engin ou sous-marin autonome. Dans ce cas, l'engin marin ou sous- marin 7 est muni d'un lien temporaire pendant les phases de mise à l'eau et de récupération : la liaison entre le câble de traction 1 6 et l'engin 7 est dite indirecte. Lors de l'utilisation d'un engin marin ou sous-marin autonome, ce mode de réalisation peut être couplé, ou remplacé par un mode de réalisation selon lequel au moins un des éléments de protection 5 possède un dispositif d'accroché avec l'engin 7, permettant de lier l'engin 7 et le ou les éléments de protection lors de leur mise en contact au début, par exemple, d'une récupération de l'engin 7. The raising or lowering of the marine or underwater vehicle 7 is provided by a traction means 14 composed of the traction cable 1 6, integral with the marine or underwater vehicle 7, and a winch 15, secured to the carrier vessel 6, which makes it possible to tow the cable 1 6 during a recovery phase, or to release the cable 1 6 during a launching phase, thanks to a third motor means 20 capable of imposing a second engine torque on the winch 15. In a particular embodiment, the marine or underwater vehicle 7 may be a machine or autonomous submarine. In this case, the marine or underwater vehicle 7 is provided with a temporary link during the launching and recovery phases: the connection between the traction cable 1 6 and the machine 7 is said to be indirect . When using a marine or underwater autonomous device, this embodiment can be coupled, or replaced by an embodiment in which at least one of the protection elements 5 has a device for hanging with the 7, to link the machine 7 and the one or more protective elements when they come into contact at the beginning, for example, of a recovery of the machine 7.
La figure 3 présente également un élément de surélévation 18, situé en bordure de la rampe 1 1 . Son fonctionnement est détaillé dans la description de la figure 4. La figure 3 illustre un exemple de mise en contact de l'élément de protection 5 avec l'élément de surélévation 18 pendant la phase de récupération ou la mise à l'eau. La figure 4 présente une vue schématique en perspective de l'ensemble du système quand l'engin marin ou sous-marin 7 est entièrement remonté sur la rampe 1 1 . Selon un mode de réalisation présenté dans cette figure, l'engin marin ou sous-marin 7 a été récupéré à l'aide du dispositif décrit dans la figure 1 où les deux éléments de protection 5 sont installés de part et d'autre du chariot 2 et sont solidaires entre eux. Cette caractéristique permet à l'engin marin ou sous-marin 7 de franchir la marche située entre l'extrémité de la rampe 1 1 et la surface de l'eau 25 sans que le nez, ou l'avant de l'engin marin ou sous-marin 7 ne soit en contact avec la rampe 1 1 . Cette méthode permet d'éviter des chocs capables d'endommager des éléments embarqués fragiles tels que des éléments constitutifs de capteurs, en particulier d'un sonar. Figure 3 also shows a raising element 18, located at the edge of the ramp 1 1. Its operation is detailed in the description of FIG. 4. FIG. 3 illustrates an example of putting the protection element 5 into contact with the raising element 18 during the recovery phase or the launching. Figure 4 shows a schematic perspective view of the entire system when the marine or submarine 7 is fully reassembled on the ramp 1 1. According to an embodiment presented in this figure, the marine or underwater vehicle 7 was recovered using the device described in Figure 1 where the two protection elements 5 are installed on either side of the truck 2 and are interdependent with each other. This characteristic allows the marine or underwater vehicle 7 to cross the step located between the end of the ramp 1 1 and the surface of the water 25 without the nose, or the front of the marine gear or submarine 7 is not in contact with the ramp 1 1. This method makes it possible to avoid shocks capable of damaging fragile onboard elements such as elements constituting sensors, in particular a sonar.
La figure 4 permet d'illustrer la zone de glissement 17 située le long de la rampe 1 1 . Elle reste en contact avec le ou les éléments de protection 5 lors du glissement du chariot 2 le long de la rampe 1 1 . Selon un mode de réalisation considéré, la partie protectrice 4 comprend un rouleau 10 monté à l'une de ses extrémités et pivotant selon un axe parallèle à la surface de l'eau 25, tel qu'illustré dans la figure 3. Ce rouleau 10 permet à la partie protectrice 4 d'éviter les frottements avec la zone de glissement 17 lors du passage de l'engin marin ou sous-marin 7 sur la rampe 1 1 . Selon un autre mode de réalisation de l'invention, la partie protectrice 4 comprend un ou plusieurs rouleaux 10 montés sur une partie de ladite partie protectrice 4 apte à coopérer avec ladite zone de glissement 17 et/ou un élément de surélévation 18, et pivotant selon un second axe parallèle à la surface de l'eau 25 quand le système est fixé au navire 6. Ces rouleaux permettent d'éviter les frottements entre les éléments de protection 5 et la zone de glissement 17 et/ou un ou des éléments de surélévation 18. Ils sont par exemple agencés sous la ou les parties protectrices 4 dans le référentiel du navire. Selon le mode de réalisation considéré, la zone de glissement 17 permet aussi de supporter l'élément de surélévation 18, qui lui est solidaire, dans le but de mettre en mouvement l'élément de protection 5 par contact. FIG. 4 illustrates the sliding zone 17 located along the ramp 11. It remains in contact with the protection element (s) 5 during the sliding of the carriage 2 along the ramp 1 1. According to one embodiment, the protective part 4 comprises a roller 10 mounted at one of its ends and pivoting along an axis parallel to the surface of the water 25, as illustrated in FIG. allows the protective part 4 to avoid friction with the sliding zone 17 during the passage of the marine or submarine 7 on the ramp 1 1. According to another embodiment of the invention, the protective part 4 comprises one or a plurality of rollers 10 mounted on a portion of said protective portion 4 adapted to cooperate with said sliding zone 17 and / or an elevating element 18, and pivotable along a second axis parallel to the surface of the water 25 when the system is fixed to the ship 6. These rollers prevent friction between the protection elements 5 and the sliding zone 17 and / or one or more elevation elements 18. They are for example arranged under the protective part or parts 4 in the repository of the ship. According to the embodiment considered, the sliding zone 17 also makes it possible to support the raising element 18, which is integral with it, in order to move the protective element 5 by contact.
La figure 4 illustre de plus des moyens de protection et de glissement 30 montés sur la rampe 1 1 et prévus pour favoriser la progression de l'engin 7 le long de la rampe 1 1 , sous l'action de la traction exercée par le câble de traction 1 6 et de la gravité. Ces moyens sont par exemple des rouleaux ou des galets roulants disposés latéralement sur le fond de la rampe 1 1 et sur lesquels roule l'engin 7. FIG. 4 further illustrates protection and sliding means 30 mounted on the ramp 1 1 and designed to promote the progression of the vehicle 7 along the ramp 1 1, under the action of the traction exerted by the cable traction 1 6 and gravity. These means are for example rollers or rollers arranged laterally on the bottom of the ramp 1 1 and on which the machine 7 rolls.
La figure 5 est une séquence de vues schématiques de profil de l'ensemble du système L.A.R.S. décrivant une phase complète de récupération de l'engin marin ou sous-marin 7. L'un des problèmes techniques principaux peut être illustré par la figure 5. F. Cette figure illustre la marche verticale, de hauteur h, présente entre la surface de l'eau 25 et l'extrémité de la rampe 1 1 inclinée. Cette paroi verticale représente une source d'impacts ou de chocs avec la paroi de l'engin marin ou sous-marin 7 lors de sa mise à l'eau et de sa récupération, notamment lors du passage de l'avant de l'engin marin ou sous-marin 7 entre la surface de l'eau 25 et le bas de la rampe. La présente invention a pour effet de permettre la mise à l'eau et la récupération de l'engin marin ou sous-marin 7, en évitant tout contact entre la marche précédemment décrite et l'avant de l'engin marin ou sous- marin 7. La séquence de récupération est décrite à partir de la figure 5. A. Cette figure illustre une phase d'approche de l'engin marin ou sous-marin 7. Ce dernier est immergé et solidaire du câble de traction 1 6. On peut cependant noter qu'un autre mode de réalisation peut inclure un engin marin ou sous-marin 7 dont la navigation est en surface lors de cette phase de la récupération. Le chariot 2 est en position reculée, soit à l'extrémité basse de la rampe 1 1 par effet de la gravité ou par effet du second moyen moteur. Les éléments de protection 5 sont en position basse, soit pivotés vers le bas, de manière à être immergés pour réceptionner l'engin marin ou sous-marin 7. Dans l'exemple de la figure 5. A, l'axe principal d'inertie des éléments de protection décrit un angle avec la surface de l'eau 25 compris entre 80° et 90°. FIG. 5 is a sequence of schematic profile views of the entire LARS system describing a complete recovery phase of the marine or underwater vehicle 7. One of the main technical problems can be illustrated in FIG. 5. F. This figure illustrates the vertical step, of height h, present between the surface of the water 25 and the end of the ramp 1 1 inclined. This vertical wall represents a source of impacts or shocks with the wall of the marine or submarine machine 7 when it is launched and recovered, especially when passing from the front of the machine marine or submarine 7 between the surface of the water 25 and the bottom of the ramp. The present invention has the effect of allowing the launching and recovery of the marine or underwater vehicle 7, avoiding any contact between the previously described step and the front of the marine or underwater vehicle 7. The recovery sequence is described starting from FIG. 5. A. This figure illustrates a phase of approach of the marine or submarine machine 7. This latter is immersed and integral with the traction cable 1 6. however, it may be noted that another embodiment may include a marine or underwater craft 7 whose navigation is on the surface during this phase of recovery. The carriage 2 is in the retracted position, either at the lower end of the ramp 1 1 by effect of gravity or by the effect of the second motor means. The protection elements 5 are in the low position, either pivoted downwards, so as to be immersed to receive the marine or underwater vehicle 7. In the example of FIG. 5.A, the main axis of Inertia of the protection elements describes an angle with the surface of the water between 80 ° and 90 °.
La figure 5.B illustre la phase d'accostage de l'engin marin ou sous-marin 7. Le câble de traction 1 6 est ravalé par le treuil 15. Dans cet exemple de réalisation, l'engin marin ou sous-marin 7 possède des ailes 12. La traction du câble entraîne les ailes 12 en butée des éléments de protection 5. FIG. 5.B illustrates the docking phase of the marine or underwater vehicle 7. The towing cable 16 is swallowed by the winch 15. In this embodiment, the marine or underwater machine 7 has wings 12. The traction of the cable drives the wings 12 in abutment of the protective elements 5.
La figure 5.C illustre la phase de montée de la marche de l'avant de l'engin marin ou sous-marin 7. Le câble de traction 1 6 continue d'être ravalé par le treuil 15. Les éléments de protection 5 sont contraints par les ailes 12 de l'engin marin ou sous-marin 7, par la zone glissement 17 et par les éléments de surélévation 18 : les éléments de protection 5 pivotent alors autour du chariot 2, leur rotation est forcée par la zone de glissement 17et/ou un élément de surélévation 18. Cette rotation des éléments de protection 5 soulève l'avant de l'engin marin ou sous-marin 7 pour l'amener au niveau de la rampe. L'avant de l'engin marin ou sous-marin 7 ne touche alors aucun élément du L.A.R.S., ce qui permet de protéger les capteurs de chocs potentiellement destructeurs. FIG. 5.C illustrates the rising phase of the forward step of the marine or underwater vehicle 7. The pulling cable 1 6 continues to be swept by the winch 15. The protection elements 5 are constrained by the wings 12 of the marine or underwater vehicle 7, by the sliding zone 17 and by the raising elements 18: the protection elements 5 then pivot around the carriage 2, their rotation is forced by the sliding zone 17 and / or an elevation element 18. This rotation of the protection elements 5 lifts the front of the marine or underwater vehicle 7 to bring it to the level of the ramp. The front of the marine or underwater craft 7 then does not touch any LARS element, which helps protect potentially damaging shock sensors.
La figure 5.D et 5.E illustrent la suite de la remontée de l'engin marin ou sous-marin 7 sur la rampe 1 1 . Dans la figure 5.D, le câble de traction 1 6 continue d'être ravalé par le treuil 15. Les éléments de protection 5 continuent de pivoter autour du chariot 2, de paire avec le glissement vers l'avant du chariot 2 le long de la rampe 1 1 . Les éléments de protection 5 glissent, ou roulent selon une réalisation particulière, sur l'élément de surélévation 18, permettant à l'avant de l'engin marin ou sous-marin 7 d'être encore surélevé. Le corps de l'engin marin ou sous-marin 7, plus résistant que l'avant, s'appuie sur des moyens de protection et de glissement 30 de la rampe, en l'occurrence des rouleaux. Dans la figure 5.E, le câble de traction 1 6 continue d'être ravalé par le treuil 15. Lors de la traction, l'engin marin ou sous-marin prend appui sur les moyens de protection et de glissement 30 de la rampe 1 1 jusqu'à se reposer sur la rampe 1 1 . Le contact entre les éléments de protection 5 et les éléments de surélévation 18 cesse et les éléments de protection 5 glissent ou roulent sur les zones de glissement 17. Figure 5.D and 5.E illustrate the continuation of the ascent of the marine or underwater vehicle 7 on the ramp 1 1. In FIG. 5.D, the pulling cable 16 continues to be swept by the winch 15. The protection elements 5 continue to pivot about the carriage 2, together with the forward sliding of the carriage 2 along of the ramp 1 1. The protective elements 5 slide, or roll in a particular embodiment, on the raising element 18, allowing the front of the marine or underwater vehicle 7 to be further elevated. The body of the marine or submarine machine 7, more resistant than the front, is based on means of protection and sliding 30 of the ramp, in this case rollers. In FIG. 5.E, the pulling cable 1 6 continues to be swept by the winch 15. During the pulling, the marine or underwater machine bears on the means of protection and sliding 30 of the ramp 1 1 to rest on the ramp 1 1. The contact between the protection elements 5 and the elevation elements 18 ceases and the protection elements 5 slide or roll on the sliding zones 17.
La figure 5. F illustre l'engin marin ou sous-marin 7 monté au bout de la rampe 1 1 . Les éléments de protection 5 ne sont plus dans leur position surélevée. L'avant de l'engin marin ou sous-marin 7 repose alors sur la rampe 1 1 par l'intermédiaire de son corps. Les éléments de protection 5 restent en contact avec les ailes 12 et ainsi limitent ou empêchent notamment le roulis de l'engin marin ou sous-marin 7. Figure 5. F illustrates the marine or underwater vehicle 7 mounted at the end of the ramp 1 1. The protective elements 5 are no longer in their raised position. The front of the marine or underwater vehicle 7 then rests on the ramp 1 1 via its body. The protection elements 5 remain in contact with the wings 12 and thus limit or prevent in particular the roll of the marine or underwater vehicle 7.
L'assiette de l'engin marin ou sous-marin 7 varie, lors d'une mise à l'eau ou d'une récupération, en fonction de son assiette initiale et des contraintes imposées par le système. Dans des modes de réalisation de l'invention, la norme de la variation d'assiette maximale de l'engin marin ou sous-marin 7 peut être comprise entre 0 et 90°. Le système est apte à modifier l'assiette dudit engin marin ou sous-marin lors de la mise à l'eau ou de la récupération dudit engin marin ou sous-marin. The attitude of the marine or submarine machine 7 varies, during launching or recovery, according to its initial attitude and the constraints imposed by the system. In embodiments of the invention, the standard of the maximum attitude variation of the marine or underwater vehicle 7 may be between 0 and 90 °. The system is capable of modifying the attitude of said marine or submarine device when launching or recovering said marine or underwater vehicle.
Dans une réalisation particulière de l'invention, l'engin marin ou sous-marin 7 ne comprend ni aile 12 ni protubérance latérale. Les phases de récupération et la mise à l'eau sont analogues à celles illustrées dans la figure 5 : dans cette réalisation, la ou les parties protectrices 4 sont directement en contact avec la coque de l'engin marin ou sous-marin 7. In a particular embodiment of the invention, the marine or underwater vehicle 7 comprises neither wing 12 nor lateral protuberance. The recovery phases and the launching are similar to those illustrated in FIG. 5: in this embodiment, the protective part or parts 4 are directly in contact with the hull of the marine or underwater vehicle 7.
