ARRIERE-PLAN TECHNOLOGIQUETECHNOLOGICAL BACKGROUND

Les engins autonomes sous-marins sont le plus souvent appelés AUV (Autonomous Underwater Vehicle). On connaît différents systèmes de déploiement et récupération d'engins autonomes sous-marins à partir de navires porteurs ou depuis la terre. Ces systèmes peuvent être des rampes de lancement et de récupération, des paniers flottants ou suspendus, ou tout simplement des apparaux de levage tels que des grues ou des portiques. Ces systèmes sont efficaces pour les phases de déploiement des engins autonomes sous-marins mais moins efficaces pour la récupération.Autonomous underwater vehicles are most often called AUV (Autonomous Underwater Vehicle). Various systems for the deployment and recovery of autonomous underwater vehicles from carrier ships or from land are known. These systems can be launch and recovery ramps, floating or suspended baskets, or simply lifting devices such as cranes or gantries. These systems are effective for the deployment phases of autonomous underwater vehicles but less effective for recovery.

L'une des difficultés concerne l'arrimage de l'engin autonome sous-marin en vue de sa récupération, en effet, qu'il s'agisse de rampes ou de manutention, il est la plupart du temps nécessaire d'arrimer l'engin autonome sous-marin au préalable. Or, il est difficile voir quelquefois impossible d'arrimer un engin à la mer à partir d'un navire sans que la manoeuvre soit exécutée par des hommes ce qui représente un risque important et qui est impossible à réaliser lorsque l'on souhaite récupérer un engin autonome sous-marin à partir d'un navire qui est autonome ou télé-opéré.One of the difficulties concerns the stowage of the autonomous underwater vehicle with a view to its recovery, indeed, whether it is a question of ramps or handling, it is most of the time necessary to stow the autonomous underwater vehicle beforehand. However, it is difficult or sometimes impossible to secure a machine at sea from a ship without the maneuver being carried out by men, which represents a significant risk and which is impossible to carry out when one wishes to recover a autonomous underwater vehicle from a ship that is autonomous or remotely operated.

D'autres systèmes existants s'apparentent à des paniers dans lequel l'engin autonome sous-marin vient se loger avant d'être hissé à bord, certains encore sont des rampes avec tapis roulant sur lequel l'engin autonome sous-marin vient s'échouer avant d'être hissé à bord par le tapis roulant.Other existing systems are similar to baskets in which the autonomous underwater vehicle is housed before being hoisted on board, some are ramps with conveyor belt on which the autonomous underwater vehicle comes s fail before being hoisted on board by the conveyor belt.

L'un des inconvénients de tous ces systèmes tient aux mouvements des moyens de récupération. Soit ces mouvements sont imprimés à cet outil de récupération par le navire porteur, soit par les vagues dans le cas des paniers flottants.One of the drawbacks of all these systems relates to the movements of the recovery means. Either these movements are imparted to this recovery tool by the carrying vessel, or by the waves in the case of floating baskets.

Par ailleurs, il existe différents systèmes d'accostage automatisés appelés en anglais « Homing » permettant à un engin autonome sous-marin de venir automatiquement accoster sur ou dans une station d'accueil. Ces systèmes d'accostage automatisés utilisent classiquement des signaux acoustiques et/ou optiques afin que l'engin autonome sous-marin retrouve et reconnaisse l'emplacement de la station d'accueil et puisse communiquer avec ladite station d'accueil. Ils sont efficaces si et seulement si la station d'accueil est presque immobile.Furthermore, there are various automated docking systems called “Homing” in English, allowing an autonomous underwater vehicle to automatically come and dock on or in a docking station. These automated docking systems conventionally use acoustic and/or optical signals so that the autonomous underwater vehicle finds and recognizes the location of the docking station and can communicate with said docking station. They are effective if and only if the docking station is almost stationary.

OBJET DE L'INVENTIONOBJECT OF THE INVENTION

Afin de remédier aux inconvénients précités de l'état de la technique, la présente invention propose un système à véhicule subaquatique télé-opéré (ROV pour Remotely Operated Vehicle) par liaison filaire, donc filoguidé, et qui reste sous l'eau au moment du déploiement et de la récupération de l'engin autonome sous-marin. Avant le déploiement et après la récupération, l'engin autonome sous-marin est transporté par le véhicule subaquatique. Après le déploiement et avant la récupération, l'engin autonome sous-marin est séparé du véhicule subaquatique et peut naviguer d'une manière autonome.In order to remedy the aforementioned drawbacks of the state of the art, the present invention proposes a system with a remotely operated underwater vehicle (ROV for Remotely Operated Vehicle) by wire connection, therefore wire-guided, and which remains under water at the time of the deployment and recovery of the autonomous underwater vehicle. Prior to deployment and after recovery, the autonomous underwater vehicle is transported by the underwater vehicle. After deployment and before recovery, the autonomous underwater vehicle is separated from the underwater vehicle and can navigate autonomously.

En dehors des périodes où se déroule le déploiement et la récupération de l'engin autonome sous-marin, le véhicule subaquatique filoguidé peut être ramené sur ou dans ou contre le navire porteur pour stockage avec ou, éventuellement, sans son engin autonome sous-marin.Apart from the periods when the deployment and recovery of the autonomous underwater vehicle takes place, the underwater wire-guided vehicle can be brought back on or in or against the carrier vessel for storage with or, possibly, without its autonomous underwater vehicle. .

Le véhicule subaquatique est motorisé et il comporte des moyens de propulsion et de guidage, et il est capable, grâce à des moyens de stabilisation, de maintenir sa position sous l'eau selon tous les axes, c'est-à-dire trois axes, soit six degrés de liberté, et il n'est donc pas soumis aux mouvements des vagues et du navire porteur lors du déploiement et de la récupération de l'engin autonome sous-marin car il est en plongée.The underwater vehicle is motorized and it comprises propulsion and guidance means, and it is capable, thanks to stabilization means, of maintaining its position under water along all axes, that is to say three axes. , ie six degrees of freedom, and it is therefore not subject to the movements of the waves and of the carrier vessel during the deployment and recovery of the autonomous underwater vehicle because it is submerged.

Le véhicule subaquatique comporte une station d'accueil dans ou contre laquelle au moins un engin autonome sous-marin peut venir se loger automatiquement. Cette station d'accueil est généralement de forme proche d'un cylindre évasé au niveau de l'embouchure, c'est-à-dire en forme d'entonnoir, et elle est équipée d'un système d'accostage automatisé pour l'engin autonome sous-marin. Ce véhicule subaquatique avec station d'accueil peut être déployé à partir d'un navire porteur à équipage ou sans équipage et dans ce dernier cas d'un navire porteur autonome ou filoguidé ou remorqué.The underwater vehicle comprises a docking station in or against which at least one autonomous underwater vehicle can come to be housed automatically. This docking station is generally of a shape close to a flared cylinder at the level of the mouth, that is to say funnel-shaped, and it is equipped with an automated docking system for the autonomous underwater vehicle. This underwater vehicle with docking station can be deployed from a crewed or unmanned carrier vessel and, in the latter case, from an autonomous or wire-guided or towed carrier vessel.

Ainsi, l'invention concerne tout d'abord, un système pour le déploiement et la récupération d'un engin autonome sous-marin par un navire porteur de surface, le navire porteur comportant une coque avec une carène, l'engin autonome sous-marin comportant des moyens de propulsion, de guidage et de stabilisation.Thus, the invention relates first of all to a system for the deployment and recovery of an autonomous underwater vehicle by a surface carrier vessel, the carrier vessel comprising a hull with a hull, the autonomous underwater vehicle boat comprising means of propulsion, guidance and stabilization.

Grâce à l'invention, le déploiement et la récupération de l'engin autonome sous-marin sont simplifiés puisqu'il n'est plus nécessaire d'avoir à le manipuler pour le libérer ou pour le saisir/l'agripper dans l'eau à partir d'un navire qui est soumis aux mouvements de la mer, rafales de vent... L'engin autonome sous-marin est récupéré ou libéré sous l'eau, à partir du véhicule subaquatique qui est relié par un câble au navire porteur, donc permettant un découplage des mouvements respectifs du véhicule subaquatique et du navire porteur. En outre, le véhicule subaquatique comporte des moyens notamment de stabilisation facilitant l'action des moyens d'accostage automatisés entre le véhicule subaquatique et l'engin autonome sous-marin. La récupération pour stockage du véhicule subaquatique sur ou dans ou sous le navire porteur et sa mise à l'eau/libération, sont également particulièrement simples du fait de la liaison filaire par câble entre le navire porteur et le véhicule subaquatique : il suffit de d'enrouler ou de dérouler le câble selon le cas.Thanks to the invention, the deployment and recovery of the autonomous underwater vehicle are simplified since it is no longer necessary to have to manipulate it to release it or to grasp/grip it in the water. from a ship which is subject to the movements of the sea, gusts of wind... The autonomous underwater vehicle is recovered or released under water, from the underwater vehicle which is connected by a cable to the ship carrier, thus allowing decoupling of the respective movements of the underwater vehicle and the carrier vessel. In addition, the underwater vehicle comprises means in particular for stabilization facilitating the action of the automated docking means between the underwater vehicle and the autonomous underwater vehicle. The recovery for storage of the underwater vehicle on or in or under the carrier vessel and its launching/release are also particularly simple due to the wired cable connection between the carrier vessel and the underwater vehicle: it suffices to d wrap or unwind the cable as appropriate.

DispositifDevice

Sur la figure 1, on a représenté un premier exemple de système 1 dont le navire porteur 2 est un navire de surface monocoque perce-vague et qui comporte une quille 20 destinée à le stabiliser. Par rapport aux navires à propulsion mécanique classiques qui n'en n'ont pas besoin, et en particulier les navires à vitesse élevée pour lesquels ce serait un handicap, le navire porteur 2 perce-vague monocoque comporte une quille 20 qui est utile à sa stabilité du fait que ce dernier a une forme très effilée/fusiforme contrairement aux navires à propulsion mécanique classiques. Ce navire porteur perce-vague monocoque est notamment destiné à réaliser des mesures acoustiques dans l'eau et qu'il n'est pas destiné à « voler » au-dessus de l'eau, sa quille comportant, outre le véhicule subaquatique transporté, des appareils de mesure devant rester dans l'eau. Il doit donc pouvoir percer les vagues grâce à une proue 25 en lame de couteau tout en navigant à une vitesse élevée et avec une dépense en énergie réduite.On the figure 1 , there is shown a first example of a system 1 whose carrying vessel 2 is a wave-piercing monohull surface vessel and which comprises a keel 20 intended to stabilize it. Compared to conventional mechanically propelled ships which do not need it, and in particular high-speed ships for which it would be a handicap, the monohull wave-piercing carrier ship 2 comprises a keel 20 which is useful for its stability due to the fact that the latter has a very tapered/fusiform shape unlike conventional mechanically propelled vessels. This monohull wave-piercing carrier vessel is intended in particular to carry out acoustic measurements in the water and that it is not intended to "fly" above the water, its keel comprising, in addition to the underwater vehicle transported, measuring devices that must remain in the water. He must therefore be able pierce the waves thanks to a knife-edge 25 bow while sailing at high speed and with reduced energy expenditure.

Ce navire porteur 2 est sans équipage et est autonome car préprogrammé et/ou télé-opéré/télécommandé pour ce qui concerne notamment sa navigation. Il comporte des moyens de navigation intégrés qui sont particulièrement utiles dans le cas d'un drone.This carrier vessel 2 is unmanned and is autonomous because it is pre-programmed and/or tele-operated/remote-controlled with regard in particular to its navigation. He includes integrated navigation means which are particularly useful in the case of a drone.

Dans ce premier exemple, le navire porteur 2 a une quille amovible qui comporte à son extrémité inférieure, immergée, une gondole 21 formant une zone de stockage pour un véhicule subaquatique 3. Des capteurs, en particulier acoustiques 27, sont fixés contre la gondole 21. Dans une variante, la gondole peut être remplacée par un bulbe contenant ou supportant des appareils de mesures sous-marines et lequel bulbe comporte alors la zone de stockage du véhicule subaquatique 3. Sur la figure 1, un engin autonome sous-marin 4 est installé dans le véhicule subaquatique 3. Une telle configuration où le véhicule subaquatique 3 est stocké sur le navire porteur peut correspondre à une fin de mission/d'utilisation ou à un déplacement vers une zone d'utilisation où l'engin autonome sous-marin 4 pourra être libéré.In this first example, the carrier vessel 2 has a removable keel which comprises at its lower end, submerged, a gondola 21 forming a storage area for an underwater vehicle 3. Sensors, in particular acoustic 27, are fixed against the gondola 21 Alternatively, the gondola can be replaced by a bulb containing or supporting underwater measuring devices and which bulb then includes the storage area of the underwater vehicle 3. On the figure 1 , an autonomous underwater vehicle 4 is installed in the underwater vehicle 3. Such a configuration where the underwater vehicle 3 is stored on the carrier vessel may correspond to an end of mission/use or to a move to an area of use where the autonomous underwater vehicle 4 can be released.

Le navire porteur 2 comporte des moyens de propulsion, ici à hélice 23, et un dispositif de guidage 24 à type de gouvernail. Le navire porteur 2 comporte un kiosque 22 hors d'eau, au-dessus de la ligne de flottaison, avec des appareils 26 notamment destinés à des mesures et/ou communications, en particulier dans le cas où le navire porteur serait télécommandé par ondes radio.The carrier vessel 2 comprises means of propulsion, here a propeller 23, and a guide device 24 of the rudder type. The carrier vessel 2 comprises a kiosk 22 out of the water, above the waterline, with devices 26 in particular intended for measurements and/or communications, in particular in the case where the carrier vessel is remotely controlled by radio waves. .

La quille 20 est amovible et elle peut monter et descendre à travers un puit de quille de la coque du navire porteur. On remarque que le kiosque 22 est dans l'axe de la quille 20 et ce kiosque sert en outre à loger intérieurement l'extrémité supérieure de la quille 20 remontée dans un espace de stockage de quille du kiosque.The keel 20 is removable and can move up and down through a keel well in the hull of the carrier vessel. It will be noted that the kiosk 22 is in the axis of the pin 20 and this kiosk also serves to accommodate internally the upper end of the pin 20 raised in a pin storage space of the kiosk.

Dans une variante, on peut prévoir dans la coque ou carène, dans la région de la quille 20, un renfoncement permettant de recevoir, lorsque la quille est remontée, au moins en partie la gondole 21 ou le bulbe ainsi qu'éventuellement le véhicule subaquatique 3 et son engin autonome sous-marin 4, et de préférence d'une manière à être dans le gabarit général de la coque et afin de diminuer la résistance à l'avancement du navire porteur dans la configuration de stockage du véhicule subaquatique 3.In a variant, it is possible to provide in the hull or hull, in the region of the keel 20, a recess making it possible to receive, when the keel is raised, at least in part the gondola 21 or the bulb as well as possibly the underwater vehicle 3 and its autonomous underwater vehicle 4, and preferably in such a way as to be in the general template of the hull and in order to reduce the resistance to the advancement of the carrier vessel in the storage configuration of the underwater vehicle 3.

Sur la figure 2, le système 1 est passé en configuration d'utilisation dans laquelle le véhicule subaquatique 3 est séparé du navire porteur 2. Un câble de liaison 5 relie le navire porteur 2 au véhicule subaquatique 3 afin que ce dernier soit télé-opéré/filoguidé. Cette figure peut correspondre au début de l'utilisation et l'engin autonome sous-marin 4 sera ensuite libéré, ou correspondre à la fin de l'utilisation après la récupération de l'engin autonome sous-marin 4 dans le véhicule subaquatique 3, le système passant ensuite en configuration de stockage lorsque le véhicule subaquatique 3 sera de nouveau fixé au navire porteur 2.On the figure 2 , the system 1 is switched to the configuration of use in which the underwater vehicle 3 is separated from the carrier vessel 2. A connection cable 5 connects the carrier vessel 2 to the underwater vehicle 3 so that the latter is remotely operated/wire-guided. This figure may correspond to the start of use and the autonomous underwater vehicle 4 will then be released, or correspond to the end of use after the recovery of the autonomous underwater vehicle 4 in the underwater vehicle 3, the system then switches to storage configuration when the underwater vehicle 3 is again attached to the carrier vessel 2.

Sur la figure 3, le système 1 est toujours en configuration d'utilisation et cette fois l'engin autonome sous-marin 4 se libère du véhicule subaquatique 3 ou, inversement, revient dans ce dernier pour être récupéré.On the picture 3 , the system 1 is still in the use configuration and this time the autonomous underwater vehicle 4 is released from the underwater vehicle 3 or, conversely, returns to the latter to be recovered.

La figure 4 montre une variante dans laquelle la libération ou la récupération de l'engin autonome sous-marin 4 peut se faire alors que le véhicule subaquatique est fixé au navire porteur comme dans la configuration de stockage. On pourra utiliser cette variante dans le cas où le navire porteur n'est pas soumis à des mouvements, c'est-à-dire qu'il est sur une étendue d'eau calme, sans vague ou houle.There figure 4 shows a variant in which the release or recovery of the autonomous underwater vehicle 4 can be done while the underwater vehicle is attached to the carrier vessel as in the storage configuration. This variant can be used in the case where the carrier ship is not subject to movements, that is to say it is on a calm expanse of water, without waves or swells.

L'engin autonome sous-marin 4 est, comme son nom l'indique, un dispositif qui se déplace indépendamment du véhicule subaquatique 3 lorsqu'il a été libéré, contrairement au véhicule subaquatique 3 qui reste relié par un câble au navire porteur. L'engin autonome sous-marin 4 comporte donc des moyens de propulsion, à hélice dans cet exemple et des moyens de guidage ainsi que, de préférence, des moyens de stabilisation. Les actions des moyens de propulsion de guidage et éventuellement de stabilisation de l'engin autonome sous-marin, sont préprogrammées et/ou télé-opérées/télécommandées. Ces actions peuvent aussi dépendre de mesures effectuées par des capteurs.The autonomous underwater vehicle 4 is, as its name suggests, a device which moves independently of the underwater vehicle 3 when it has been released, unlike the underwater vehicle 3 which remains connected by a cable to the carrier vessel. The autonomous underwater vehicle 4 therefore comprises means of propulsion, with a propeller in this example and means of guidance as well as, preferably, means of stabilization. The actions of the propulsion means for guidance and possibly for stabilization of the autonomous underwater vehicle are preprogrammed and/or remotely operated/remotely controlled. These actions may also depend on measurements made by sensors.

Les moyens de propulsion et de guidage de l'engin autonome sous-marin peuvent être soit distincts soit combinés, dans ce dernier cas ces moyens peuvent être des propulseurs orientables. On peut également prévoir que le sens de rotation de l'hélice ou de la turbine du dispositif de propulsion et possiblement guidage, peut être inversé.The means of propulsion and guidance of the autonomous underwater vehicle can be either distinct or combined, in the latter case these means can be steerable thrusters. Provision can also be made for the direction of rotation of the propeller or of the turbine of the propulsion and possibly guidance device to be reversed.

Le véhicule subaquatique 3 comporte des moyens de propulsion et de guidage, par exemple orientable à turbine pour jet/réaction ou à déflexion variable de jet, ainsi que des moyens de stabilisation permettant une stabilisation du véhicule subaquatique selon trois axes.The underwater vehicle 3 comprises means of propulsion and guidance, for example orientable with a turbine for jet/reaction or with variable jet deflection, as well as stabilization means allowing stabilization of the underwater vehicle along three axes.

On comprend que si les moyens de propulsion, de guidage et de stabilisation, pour chacun du navire porteur, du véhicule subaquatique et de l'engin autonome sous-marin, ont été séparés du point de vue de leur description pour faciliter les explications des différentes fonctions, en pratique et matériellement, ces différentes fonctions de propulsion/déplacement, de guidage/orientation, de stabilisation peuvent être réalisées avec un ou plusieurs dispositifs réalisant chacun plusieurs de ces fonctions. Ainsi, comme on l'a vu, un même dispositif orientable de propulsion à hélice ou turbine peut servir de moyen de propulsion, guidage et stabilisation. Un système de ballasts peut servir au déplacement passif, en particulier plongée ou remontée, et à l'orientation passive du véhicule subaquatique ou de l'engin autonome sous-marin.It is understood that if the means of propulsion, guidance and stabilization, for each of the carrier vessel, the underwater vehicle and the autonomous underwater vehicle, have been separated from the point of view of their description to facilitate the explanations of the different functions, in practice and materially, these various functions of propulsion/displacement, guidance/orientation, stabilization can be performed with one or more devices each performing several of these functions. Thus, as we have seen, the same steerable propeller or turbine propulsion device can serve as means of propulsion, guidance and stabilization. A ballast system can be used for passive displacement, in particular diving or ascent, and for passive orientation of the underwater vehicle or of the autonomous underwater vehicle.

Sur la figure 5, on a représenté un deuxième exemple de système 1' qui ne fait pas partie de l'invention dont le navire porteur 6 est un navire de surface plus classique ici bicoque, de type catamaran, mais qui peut être monocoque dans une variante. Cette fois, dans la configuration de stockage, le véhicule subaquatique 3 est remonté, hors d'eau, sur le pont 60 du navire porteur 6. Ce navire porteur 6 comporte une superstructure 61 destinée à un équipage assurant la navigation.On the figure 5 , there is shown a second example of a system 1′ which does not form part of the invention, the carrying vessel 6 of which is a surface vessel which is more conventional here with twin hulls, of the catamaran type, but which can be monohull in a variant. This time, in the storage configuration, the underwater vehicle 3 is raised, out of the water, onto the deck 60 of the carrier vessel 6. This carrier vessel 6 comprises a superstructure 61 intended for a crew providing navigation.

Le navire porteur 6 comporte un dispositif de récupération du véhicule subaquatique permettant de sortir de l'eau et, inversement, de mettre à l'eau ledit véhicule subaquatique. Ce dispositif de récupération est un portique 62 et un treuil motorisé 63 pour enrouler et dérouler le câble 5 de liaison entre le véhicule subaquatique 3 et le navire porteur 6. Ce dispositif de récupération à portique 62 permet également la mise à l'eau du véhicule subaquatique.The carrier vessel 6 comprises a device for recovering the underwater vehicle making it possible to get out of the water and, conversely, to launch said underwater vehicle. This recovery device is a gantry 62 and a motorized winch 63 for winding and unwinding the connecting cable 5 between the underwater vehicle 3 and the carrier vessel 6. This gantry recovery device 62 also allows the vehicle to be launched underwater.

Dans la configuration d'utilisation de la figure 6 qui ne fait pas partie de l'invention, le véhicule subaquatique 3 a été mis à l'eau et l'engin autonome sous-marin 4 est installé dans la station d'accueil du véhicule subaquatique. Sur la figure 7 qui ne fait pas partie de l'invention, l'engin autonome sous-marin 4 a été libéré.In the configuration for using the figure 6 which does not form part of the invention, the underwater vehicle 3 has been launched and the autonomous underwater vehicle 4 is installed in the docking station of the underwater vehicle. On the figure 7 which is not part of the invention, the autonomous underwater vehicle 4 has been released.

Sur la figure 8, on a représenté un troisième exemple de système 1" qui ne fait pas partie de l'invention dont le navire porteur 7 est un navire de surface particulier en ce qu'il comporte un fond submergé/ennoyé 76 qui comporte une fente 73 dans laquelle un aileron 30 axial, ici inférieur, du véhicule subaquatique peut venir coulisser. Suivant la profondeur du fond submergé 76, le véhicule peut rester subaquatique en configuration de stockage. Les deux bords latéraux 74 et 75 flottant du navire porteur 7 définissent avec le fond 76 un espace intérieur 72 submergé, ouvert vers l'arrière, de stockage du véhicule subaquatique 3 et de son engin autonome sous-marin 4. On peut prévoir un véhicule subaquatique 3 qui peut faire surface et flotter au cas où la profondeur du fond 76 serait plus faible. Dans une variante, le véhicule subaquatique 3 est stocké sous le fond 76, en dessous de la coque du navire porteur, et l'aileron axial est un aileron supérieur qui peut glisser dans la fente 73. Dans ce dernier cas, le fond 76 peut être configuré pour former un renfoncement de la carène dans lequel le véhicule subaquatique vient se placer.On the figure 8 , a third example of a system 1" has been shown which does not form part of the invention, the carrying vessel 7 of which is a particular surface vessel in that it comprises a submerged/submerged bottom 76 which comprises a slot 73 in which an axial fin 30, here lower, of the underwater vehicle can slide. Depending on the depth of the submerged bottom 76, the vehicle can remain underwater in the storage configuration. The two floating side edges 74 and 75 of the carrier vessel 7 define with the bottom 76 a submerged interior space 72, open towards the rear, for storing the underwater vehicle 3 and its autonomous underwater vehicle 4. It is possible to provide an underwater vehicle 3 which can surface and float in the event that the depth of the bottom 76 is In a variant, the underwater vehicle 3 is stored under the bottom 76, below the hull of the carrying vessel, and the axial fin is an upper fin which can slide in the slot 73. In the latter case, the bottom 76 can be configured to form a recess in the hull in which the underwater vehicle is placed.

Dans des variantes, le fond qui est partiellement submergé est une rampe de lancement et de récupération et en configuration de stockage le véhicule subaquatique peut être totalement sorti de l'eau par la rampe ou, seulement, sa partie avant sortie de l'eau, ce dernier cas étant utile si on veut utiliser les moyens de propulsion et possiblement guidage, du véhicule subaquatique pour entraîner le navire porteur ou l'aider à se déplacer, les moyens de propulsion du véhicule subaquatique, mais aussi de l'engin autonome sous-marin, restant dans l'eau.In variants, the bottom which is partially submerged is a launching and recovery ramp and in the storage configuration the underwater vehicle can be completely taken out of the water by the ramp or, only, its front part can be taken out of the water, this last case being useful if one wants to use the means of propulsion and possibly guidance, of the underwater vehicle to drive the carrier vessel or help it to move, the means of propulsion of the underwater vehicle, but also of the autonomous underwater vehicle, remaining in the water.

Comme précédemment le navire porteur 6 de la figure 8 comporte un pont 70 et une superstructure 71 destinée à un équipage assurant la navigation. On peut prévoir à l'arrière du navire porteur une ou des portes pour fermer vers l'arrière l'espace intérieur.As before, carrier vessel 6 of the figure 8 has a bridge 70 and a superstructure 71 intended for a crew providing navigation. One or more doors can be provided at the rear of the carrier ship to close the interior space to the rear.

Dans des variantes de ce troisième exemple de système 1", les bords latéraux 74, 75 flottants peuvent être constitués de boudins gonflables permettant de réaliser un navire porteur démontable et repliable.In variants of this third example of a 1" system, the floating side edges 74, 75 can be made up of inflatable tubes making it possible to produce a dismountable and foldable carrier vessel.

Dans le quatrième exemple de système représenté figure 9 qui ne fait pas partie de l'invention, le navire porteur 8 comporte une coque 84 dont la carène comporte un renfoncement 80 permettant de stocker contre la quille/carène le véhicule subaquatique 3 dans la configuration de stockage, le véhicule subaquatique pouvant en outre, dans certaines modalités, participer à la propulsion du navire porteur, en particulier dans le cas où la paroi arrière 82 du navire porteur est ouverte au niveau du renfoncement. De préférence, le câble de liaison venant du navire porteur débouche par un puit de câble 81 dans le renfoncement dans le cas où il arrive sur le haut du véhicule subaquatique mais dans d'autres modalités, il peut passer par un autre chemin, notamment si le câble arrive sur le véhicule subaquatique par l'avant ou le dessous. Un enrouleur/dérouleur 83 de câble de liaison 5 est disposé sur le pont du navire porteur.In the fourth system example shown figure 9 which is not part of the invention, the carrier vessel 8 comprises a hull 84 whose hull comprises a recess 80 making it possible to store the underwater vehicle 3 against the keel/hull in the storage configuration, the underwater vehicle also being able, in certain modalities, participate in the propulsion of the carrier vessel, in particular in the case where the rear wall 82 of the carrier vessel is open at the level of the recess. Preferably, the connection cable coming from the carrier vessel emerges via a cable well 81 in the recess in the case where it arrives at the top of the underwater vehicle but in other modalities, it can pass by another path, in particular if the cable enters the underwater vehicle from the front or the bottom. A winder/unwinder 83 of connecting cable 5 is placed on the deck of the carrying vessel.

Le véhicule subaquatique exemplifié jusqu'à présent est du type à coque mais dans d'autres modalités de mise en oeuvre, celui-ci 3' peut avoir une structure différente et notamment, comme représenté sur les figures 10 et 11, être de type à châssis/cadre 32 et à structure ouverte. Sur ces figures 10 et 11 qui ne font pas partie de l'invention, on voit les moyens de propulsion, guidage et stabilisation et notamment les hélices orientables 31 à l'intérieur du châssis 32 de la structure ouverte du véhicule subaquatique 3'. Les équipements internes du véhicule subaquatique 3' sont également visibles au sein de cette structure ouverte. Afin de faciliter la récupération automatique de l'engin autonome sous-marin au sein de la station d'accueil qui comporte un système d'accostage automatisé, l'embouchure 33 de la station d'accueil a une forme en entonnoir qui est mieux visible figure 11.The underwater vehicle exemplified so far is of the hull type but in other embodiments, the latter 3' may have a different structure and in particular, as shown in the figure 10 And 11 , be of sash/frame 32 type and open structure. On these figure 10 And 11 which do not form part of the invention, we see the means of propulsion, guidance and stabilization and in particular the steerable propellers 31 inside the frame 32 of the open structure of the underwater vehicle 3'. The internal equipment of the underwater vehicle 3' is also visible within this open structure. In order to facilitate the automatic recovery of the autonomous underwater vehicle within the docking station which comprises an automated docking system, the mouth 33 of the docking station has a funnel shape which is better visible. figure 11 .

ProcédéProcess

Le système de l'invention permet le déploiement et la récupération d'un engin autonome sous-marin par un navire porteur de surface dans des conditions optimales puisque le déploiement et surtout la récupération se font alors que l'engin autonome sous-marin est sous la surface de l'eau et n'est donc pas soumis aux mouvements des vagues ou de la houle contrairement au navire porteur. Pour cela, on met en oeuvre un véhicule subaquatique qui permet de transporter l'engin autonome sous-marin. Pour ces opérations, il faut donc faire en sorte que le véhicule subaquatique soit lui-même en plongée, sous la surface de l'eau et, de préférence lorsque le navire porteur est agité, que le véhicule subaquatique soit découplé/séparé du navire porteur.The system of the invention allows the deployment and recovery of an autonomous underwater vehicle by a surface carrier ship in optimal conditions since the deployment and especially the recovery take place while the autonomous underwater vehicle is under the surface of the water and is therefore not subject to the movements of the waves or the swell unlike the carrier vessel. For this, an underwater vehicle is used which makes it possible to transport the autonomous underwater vehicle. For these operations, it is therefore necessary to ensure that the underwater vehicle is itself submerged, under the surface of the water and, preferably when the carrier vessel is agitated, that the underwater vehicle is decoupled/separated from the carrier vessel.

L'engin autonome sous-marin 4 est configuré pour venir accoster et rentrer au moins en partie dans le véhicule subaquatique 3 filoguidé, ce dernier étant maintenu dans une attitude stable lors de cette opération. Cette opération d'accostage peut aussi être réalisée alors que le navire porteur et l'engin autonome sous-marin sont en mouvement et il est prévu un accostage jusqu'à des vitesses de 7 noeuds.The autonomous underwater vehicle 4 is configured to dock and return at least partially to the underwater vehicle 3 guided by wire, the latter being maintained in a stable attitude during this operation. This docking operation can also be carried out while the carrier vessel and the autonomous underwater vehicle are in motion and docking is provided up to speeds of 7 knots.

Ainsi, dans le cas du système 1' du deuxième exemple, où le véhicule subaquatique avec son engin autonome sous-marin est stocké hors d'eau, sur le pont du navire porteur, en configuration de stockage, on doit d'abord mettre à l'eau le véhicule subaquatique avec son engin autonome sous-marin grâce au dispositif de récupération/mise à l'eau avec son portique 62 et le treuil motorisé 63 du navire porteur. Après mise à l'eau, le véhicule subaquatique est filoguidé grâce au câble 5 et on l'amène en plongée à l'endroit où l'on souhaite libérer de la station d'accueil l'engin autonome sous-marin. Une fois l'engin autonome sous-marin libéré, celui-ci peut effectuer les missions qu'on a prévues pour lui. Une fois ces missions terminées, l'engin autonome sous-marin peut accoster automatiquement la station d'accueil du véhicule subaquatique pour sa récupération, ceci alors que le véhicule subaquatique est en plongée. Pour cet accostage automatique, des moyens complémentaires d'accostage automatisés sont mis en oeuvre entre le véhicule subaquatique et l'engin autonome sous-marin.Thus, in the case of the system 1' of the second example, where the underwater vehicle with its autonomous underwater vehicle is stored out of the water, on the deck of the carrier ship, in storage configuration, it is first necessary to the water the underwater vehicle with its autonomous underwater vehicle thanks to the recovery/launch device with its gantry 62 and the motorized winch 63 of the carrier vessel. After launching, the underwater vehicle is wire-guided using the cable 5 and it is brought underwater to the place where it is desired to release the autonomous underwater vehicle from the docking station. Once the autonomous underwater vehicle is freed, it can carry out the missions that have been planned for it. Once these missions have been completed, the autonomous underwater vehicle can automatically dock with the docking station of the underwater vehicle for its recovery, this while the underwater vehicle is submerged. For this automatic docking, additional automated docking means are implemented between the underwater vehicle and the autonomous underwater vehicle.

Dans les exemples représentés, on a représenté un seul engin autonome sous-marin 4 par véhicule subaquatique 3 mais on peut en prévoir deux ou plus. De même, on a représenté un seul véhicule subaquatique 3 par navire porteur 2, 6, 7 mais on peut en prévoir deux ou plus. D'autres modalités de mise en oeuvre sont possibles. Si, de préférence et comme représenté, l'engin autonome sous-marin 4 accoste et quitte le véhicule subaquatique 3 par l'arrière de ce dernier, on peut prévoir un accostage latéral ou par l'avant du véhicule subaquatique 3. On prévoit cependant des moyens matériels pour que le système présente une faible résistance à l'avancement sur et/ou sous l'eau et, à cette fin, on peut prévoir une porte amovible pour fermer la station d'accueil de l'engin autonome sous-marin dans laquelle l'engin autonome sous-marin 4 accoste. De même, le bulbe et la gondole, tout comme le véhicule subaquatique, ont des formes hydrodynamiques.In the examples shown, a single autonomous underwater vehicle 4 has been shown per underwater vehicle 3, but two or more can be provided. Similarly, a single underwater vehicle 3 has been shown per carrier vessel 2, 6, 7, but two or more can be provided. Other methods of implementation are possible. If, preferably and as shown, the autonomous underwater vehicle 4 docks and leaves the underwater vehicle 3 from the rear of the latter, it is possible to provide a side docking or from the front of the underwater vehicle 3. However, provision is made for material means so that the system has a low resistance to progress on and/or under water and, to this end, a removable door can be provided to close the docking station of the autonomous underwater vehicle in which the autonomous underwater vehicle 4 docks. Likewise, the bulb and the gondola, just like the underwater vehicle, have hydrodynamic shapes.
