Description

Le secteur technique de l'invention est celui des dispositifs de déroulement d'un fil assurant la transmission d'informations de toute nature (ordres ou comptes-rendus) entre deux mobiles évoluant dans un fluide.The technical field of the invention is that of unwinding devices of a thread ensuring the transmission of information of any kind (orders or reports) between two mobiles operating in a fluid.

Une des applications principales de l'invention est son utilisation pour la filotransmission entre un sous-marin ou un bâtiment de surface et une torpille autopropulsée.One of the main applications of the invention is its use for transmotransmission between a submarine or a surface vessel and a self-propelled torpedo.

En effet, dans le milieu sous-marin, la transmission d'informations non perturbées entre deux mobiles est une opération délicate, car les ondes porteuses disponibles ne permettent pas la transmission à grande distance, et ne sont en général pas fiables. La liaison de transmission à travers un câble ou un fil permet de remédier à ce problème.Indeed, in the underwater environment, the transmission of undisturbed information between two mobiles is a delicate operation, because the available carrier waves do not allow transmission over long distances, and are generally unreliable. The transmission link through a cable or wire can remedy this problem.

Pour des mobiles se déplaçant à faible vitesse et dans un périmètre réduit, les câbles utilisés sont généralement encombrants, fixés sur le mobile et se déroulent depuis le bâtiment lanceur.For mobiles moving at low speed and in a reduced perimeter, the cables used are generally bulky, fixed on the mobile and take place from the launching building.

Si le mobile doit se déplacer dans un périmètre important, quelle que soit sa vitesse, ou si les deux mobiles se déplacent simultanément dans des voies indépendantes l'une de l'autre, il est nécessaire d'utiliser des câbles de faible section qui se dévident simultanément depuis les mobiles en mouvement, ainsi chaque mobile laisse derrière lui un fil immobile dans le fluide, et les efforts sont nettement réduits.If the mobile is to move in a large perimeter, regardless of its speed, or if the two mobiles move simultaneously in tracks independent of each other, it is necessary to use cables of small section which are at the same time, they move off from moving mobiles, so that each mobile leaves behind a motionless wire in the fluid, and the forces are significantly reduced.

C'est le cas des torpilles actuelles qui se déplacent à diverses vitesses- sur une grande distance en étant contrôlées par le bâtiment qui les a lancées.This is the case of the current torpedoes that move at various speeds - over a large distance being controlled by the building that launched them.

Dans ce domaine, plusieurs réalisations ont déjà été proposées.In this area, several achievements have already been proposed.

La bobine du bâtiment lanceur est positionnée dans un conteneur verrouillé au fond du tube lance torpille. Le fil, qui se déroule depuis celui-ci, est protégé par une gaine pour éviter des ruptures dues aux frottements et aux accrochages possibles avec les parties saillantes du tube. Cette gaine de protection se déploie pendant les premiers mètres du parcours de la torpille en étant entraînée par celle-ci.The launcher building coil is positioned in a locked container at the bottom of the torpedo launch tube. The thread, which runs from there, is protected by a sheath to prevent fractures due to friction and possible clashes with the protruding parts of the tube. This protective sheath is deployed during the first meters of the course of the torpedo being driven by it.

La gaine est lestée pour s'écarter du lanceur, toutefois il a été observé qu'avec l'augmentation de la vitesse du sous-marin, elle a tendance à se rapprocher de celui-ci au point que le fil se dévide le long de la coque et risque d'être happé par le courant d'eau induit par l'hélice, ce qui est susceptible de créer sa rupture.The sheath is weighted to move away from the launcher, however it has been observed that with the increase of the speed of the submarine, it tends to get closer to it so much that the wire is unwound along the the hull and may be caught by the water current induced by the propeller, which is likely to create its rupture.

La conception actuelle du conteneur français a aussi pour conséquence de limiter la grosseur de la bobine et donc la longueur de fil emportée par le sous-marin, ce qui réduit ses capacités d'évolution pendant la phase de filoguidage.The current design of the French container also has the effect of limiting the size of the coil and therefore the length of wire carried by the submarine, which reduces its ability to evolve during the wire guidance phase.

Les sous-marins de conception française lancent leurs torpilles au moyen de vérins télescopiques, appelés « refouloir pneumatique » ; l'effort de poussée s'exerce sur l'arrière de la torpille. Jusqu'à ce jour il a toujours été possible de désaxer la sortie du fil sur une des gouvernes de l'arme de telle sorte que le refouloir n'exerce aucun effort de pression sur la gaine ou le fil. Mais les nouveaux équipements internes des torpilles limitent la place en périphérie et ne permettent plus d'appliquer cette solution, ce qui oblige à positionner la sortie de fil dans l'axe sur l'extrémité arrière de la torpille.The French-designed submarines launch their torpedoes by means of telescopic cylinders, called "pneumatic rammer"; the thrust force is exerted on the rear of the torpedo. Until now it has always been possible to offset the output of the wire on one of the control surfaces of the weapon so that the damper exerts no pressure on the sheath or the wire. But the new internal equipment torpedoes limit the periphery and no longer allow to apply this solution, which forces to position the output of wire in the axis on the rear end of the torpedo.

Dans le même domaine technique on connaît le brevet déposé sous le numéro FR 2 654 204 qui décrit un dispositif de déroulement de câble de filotransmission d'un engin se déplaçant à grande vitesse dans un fluide.In the same technical field is known the patent filed under the number FR 2,654,204 which describes a thread unwinding device of a gear moving at high speed in a fluid.

Le câble est stocké sous forme d'une bobine intégrée dans un volume existant autour d'un carénage solidaire du mobile lancé, il se déroule à la demande en fonction du déplacement de ce dernier.The cable is stored as a coil integrated into an existing volume around a fixed fairing of the launched mobile, it takes place on demand depending on the displacement of the latter.

Une des extrémités du câble est solidaire du mobile lancé, elle correspond à la couche d'enroulement de plus petit diamètre. L'autre extrémité, reliée au conteneur, se déroule depuis la couche de plus grand diamètre. Ainsi le câble se déroule en glissant sur l'arrière de la structure en formant une courbe en hélice tronconique se refermant derrière le mobile lancé, dans le même temps le fil se déroule aussi depuis la bobine du conteneur, ainsi chaque point reste alors ensuite à peu près immobile par rapport au fluide.One end of the cable is secured to the mobile launched, it corresponds to the winding layer of smaller diameter. The other end, connected to the container, runs from the larger diameter layer. Thus the cable is rolled on the back of the structure by forming a frustoconical helix curve closing behind the mobile launched, at the same time the thread also runs from the spool of the container, so each point then remains at almost immobile with respect to the fluid.

Ce conteneur peut être posé sur le pont d'un navire de surface ou lancé simultanément avec la torpille à partir d'un sous-marin en restant lié à ce dernier par un câble.This container can be placed on the deck of a surface ship or launched simultaneously with the torpedo from a submarine while remaining connected to it by a cable.

Ce dispositif de déroulement de câble présente un certain nombre d'inconvénients liés en particulier à sa forme.This cable unwinding device has a number of disadvantages related in particular to its shape.

De par la forme du conteneur, la trajectoire de ce dernier n'est pas stabilisée. Dans le cas où le conteneur et la torpille sont lancés simultanément, le conteneur risque de venir heurter la coque du sous-marin et ainsi de perturber les écoutes effectuées par ses senseurs acoustiques.By the shape of the container, the trajectory of the latter is not stabilized. In the case where the container and the torpedo are launched simultaneously, the container may come to hit the hull of the submarine and thus disrupt the listening done by its acoustic sensors.

Un autre inconvénient réside dans la taille du conteneur qui limite la longueur de fil du coté du sous-marin et donc réduit ses capacités d'évolution. La longueur de fil est également limitée par la conception de la torpille.Another disadvantage is the size of the container which limits the length of wire on the side of the submarine and therefore reduces its ability to evolve. The length of wire is also limited by the design of the torpedo.

Le but de la présente invention est de remédier aux inconvénients ci-dessus en proposant un dispositif de déroulement de fil de transmission lancé simultanément avec la torpille.The object of the present invention is to overcome the above drawbacks by proposing a transmission wire unwinding device launched simultaneously with the torpedo.

La présente invention a également pour but de fournir un dispositif éloignant le point de dévidage de la coque du lanceur.The present invention also aims to provide a device away from the unwinding point of the launcher shell.

Un autre but de l'invention est de réaliser un dispositif ayant une trajectoire stabilisée dans le fluide.Another object of the invention is to provide a device having a stabilized trajectory in the fluid.

Un autre but de l'invention est de proposer un dispositif augmentant les capacités d'évolution du sous-marin de par la longueur de fil disponible.Another object of the invention is to provide a device increasing the subsea's evolution capabilities by the length of available wire.

Pour ce faire, l'invention a pour objet un dispositif de déroulement d'un fil assurant la transmission d'informations de toute nature (ordres ou comptes-rendus) entre deux mobiles évoluant dans un fluide dans lequel le câble est enroulé sur au moins une bobine logée dans un dévidoir, ce dernier étant disposé entre les deux mobiles, dispositif caractérisé en ce que le dévidoir, dissociable des deux mobiles, comporte des moyens de stabilisation de celui-ci dans le fluide.To do this, the object of the invention is a device for unwinding a thread ensuring the transmission of information of any kind (orders or reports) between two mobiles moving in a fluid in which the cable is wound on at least a coil housed in a reel, the latter being disposed between the two mobiles, characterized in that the reel, separable from the two mobiles, comprises stabilizing means thereof in the fluid.

Les moyens de stabilisation du dévidoir comportent, de préférence, une quille combinée à un plan fixe.The stabilizer means of the reel preferably comprise a keel combined with a fixed plane.

De préférence, une entretoise de poussée, associée au dévidoir situé entre le mobile lancé et son mécanisme de lancement, assure la transmission des efforts de poussée lors du lancement.Preferably, a thrust spacer, associated with the reel located between the launched mobile and its launching mechanism, ensures the transmission of the thrust forces during launch.

Un mécanisme de liaison peut assurer temporairement la liaison entre le dévidoir et le mobile lancé. Il peut se composer d'un système bille sur ressort à contrainte de séparation tarée.A link mechanism can temporarily provide the link between the reel and the launched mobile. It may consist of a spring ball system with calibrated separation stress.

Le dispositif peut comporter une courte gaine de protection où se dévide le fil, reliée au mécanisme de liaison par l'une de ses extrémités.The device may comprise a short protective sheath where the wire is unwound, connected to the connecting mechanism by one of its ends.

Le dévidoir comporte, de préférence, une ou deux bobines.The reel preferably comprises one or two coils.

De préférence, s'il comporte deux bobines, un mécanisme régulateur de tension du fil permet de transférer l'action de dévidage de la première bobine sur la seconde en supprimant le choc occasionné par les variations de longueur de la boucle de transfert.Preferably, if it comprises two coils, a thread tension regulating mechanism makes it possible to transfer the unwinding action of the first reel to the second reel by eliminating the shock caused by the variations in the length of the transfer loop.

Un élément associé au dévidoir peut permettre de compenser les jeux entre le dernier nommé et l'extrémité du refouloir pneumatique pour éviter le choc en début de déploiement de ce dernier.An element associated with the reel can compensate for the games between the last named and the end of the pneumatic rammer to avoid shock at the beginning of deployment of the latter.

Cet élément est constitué, de préférence, d'une rondelle en mousse souple disposée entre le dévidoir et le refouloir pneumatique.This element is preferably constituted by a flexible foam washer disposed between the reel and the pneumatic rammer.

Ce dispositif présente l'avantage de permettre un lancement simultané de la torpille et du dévidoir comportant la ou les bobines de fil. Le point de dévidage se trouve ainsi à l'extérieur des deux mobiles.This device has the advantage of allowing a simultaneous launch of the torpedo and reel with the wire or reels. The unwinding point is thus outside the two mobiles.

Un autre avantage réside dans la forme du dévidoir, un plan fixe associé à la quille permet au dispositif d'avoir une trajectoire stabilisée et ainsi ne risque pas de venir heurter la coque du sous-marin.Another advantage lies in the shape of the reel, a fixed plane associated with the keel allows the device to have a stabilized trajectory and thus does not risk to hit the hull of the submarine.

Le dispositif présente également l'avantage d'éloigner du sous-marin le point de dévidage, ce qui constitue une protection face aux agressions potentielles dues aux turbulences à proximité de la coque.The device also has the advantage of moving the submarine away from the unwinding point, which is a protection against potential aggression due to turbulence near the hull.

Le dispositif offre avantageusement une grande capacité d'évolution du sous-marin en ayant la possibilité de disposer deux bobines dans le dévidoir et donc de permettre un dévidage plus rapide du fil, étant donné qu'il ne lui est pas possible de terminer son dévidage avant la fin de sa liaison avec la torpille.The device advantageously offers a great capacity of evolution of the submarine having the possibility of having two coils in the reel and thus to allow faster wire reeling, since it is not possible for him to complete his reeling before the end of his connection with the torpedo.

D'autres caractéristiques et avantages de l'invention apparaîtront dans la description détaillée, non limitative, ci-dessous.Other features and advantages of the invention will appear in the detailed description, not limiting, below.

En référence aux figures 1 à 7 on voit un dispositif de déroulement de fil de transmission entre un sous-marin et une torpille.With reference to Figures 1 to 7 we see a transmission wire unwinding device between a submarine and a torpedo.

Ce dispositif se compose d'un dévidoir (2) comportant une ou deux bobines de fil (15) et (16). Avant lancement, ce dévidoir est placé entre un mécanisme de lancement, appelé refouloir pneumatique (4), et une torpille (1), à l'intérieur d'un tube de lancement (6) du bâtiment lanceur (7). D'autres modes de lancement, comme le lancement par eau refoulée ou le lancement par auto démarrage, sont envisageables, cela implique des modifications du dévidoir qui ne sont pas représentés sur les figures.This device consists of a reel (2) having one or two reels of wire (15) and (16). Before launching, this reel is placed between a launch mechanism, called pneumatic rammer (4), and a torpedo (1), inside a launching tube (6) of the launcher building (7). Other modes of launching, such as the thrown water launch or launch by auto start, are conceivable, it implies changes reel which are not shown in the figures.

Le dévidoir est positionné dans l'axe de la torpille par un centreur (18).The reel is positioned in the axis of the torpedo by a centering device (18).

Une gaine souple (10), dans laquelle se dévide un fil (8), relie une des faces du dévidoir à la torpille par un mécanisme de liaison (9). Ce dernier est basé, par exemple, sur un système mécanique bille sur ressort comportant une contrainte de séparation tarée, identique à la solution existante (tout autre système de séparation est envisageable).A flexible sheath (10), in which a thread (8) is unwound, connects one of the reel faces to the torpedo by a connecting mechanism (9). The latter is based, for example, on a mechanical ball spring system having a calibrated separation constraint, identical to the existing solution (any other separation system is possible).

Une rondelle en mousse (19) est placée entre le refouloir pneumatique et le dévidoir, pour compenser le jeu entre les deux éléments, et absorber le choc dû au déploiement du premier nommé. La mousse utilisée est de préférence souple et élastomère, la rondelle pourra être solidaire du refouloir pneumatique, mais une mousse rigide peut également être employée, dans ce cas la rondelle sera détruite à chaque lancement et sera nécessairement solidaire du dévidoir.A foam washer (19) is placed between the pneumatic rammer and the reel, to compensate for the clearance between the two elements, and absorb the shock due to the deployment of the first named. The foam used is preferably flexible and elastomeric, the washer may be integral with the pneumatic rammer, but a rigid foam can also be used, in this case the washer will be destroyed at each launch and will necessarily be integral with the reel.

Le dévidoir est relié par un câble (5) à un boîtier (3) solidaire du tube lanceur. Ce câble, assurant la transmission des informations vers le sous-marin, est relié à la bobine de fil par une liaison (11).The reel is connected by a cable (5) to a housing (3) integral with the launcher tube. This cable, transmitting the information to the submarine, is connected to the coil of wire by a link (11).

Une entretoise de poussée (12), placé dans l'axe du dévidoir, permet de transmettre les efforts du refouloir pneumatique sur la torpille lors de la phase de lancement. Elle comporte une réservation destinée à faciliter le passage de la gaine. Le dévidoir dispose d'un plan fixe(14) assurant son éloignement par rapport au sous-marin.A thrust spacer (12), placed in the axis of the reel, makes it possible to transmit the forces of the pneumatic rammer on the torpedo during the launch phase. It includes a reservation intended to facilitate the passage of the sheath. The reel has a fixed plane (14) ensuring its distance from the submarine.

Une quille (17) positionnée sur la partie inférieure du dévidoir assure la stabilité de sa trajectoire lorsqu'il n'est plus solidaire de la torpille.A keel (17) positioned on the lower part of the reel ensures the stability of its trajectory when it is no longer secured to the torpedo.

Le dévidoir peut stocker une ou deux bobines, elles sont placées de chaque coté de ce dernier. Dans le cas où le dévidoir comporte deux bobines, le fil est continu. Pour transférer le dévidage du fil d'une bobine à l'autre sans provoquer d'à-coup, un mécanisme régulateur de tension du fil (13) permet de compenser la détente du fil en fin de dévidage de la première bobine en jouant sur la détente d'un ressort. Le fil est alors guidé par un système de poulies et le ressort assure la constance de tension du fil.The reel can store one or two reels, they are placed on each side of the reel. In the case where the reel has two coils, the wire is continuous. To transfer unwinding of the thread from one spool to the other without causing a jerk, a thread tension regulating mechanism (13) compensates for the tension of the thread at the end of unwinding of the first spool by playing on the relaxation of a spring. The wire is then guided by a system of pulleys and the spring ensures the constancy of tension of the wire.

Le fonctionnement du dispositif est le suivant : au moment du lancement, le refouloir pneumatique exerce un effort sur l'entretoise de poussée solidaire du dévidoir, qui pousse à son tour la torpille jusqu'au déploiement complet du premier nommé. L'ensemble dévidoir et torpille sort alors du tube de lancement avec une vitesse initiale.The operation of the device is as follows: at the time of launch, the pneumatic rammer exerts a force on the thrust spacer integral with the reel, which in turn pushes the torpedo until the full deployment of the first named. The reel and torpedo assembly then leaves the launch tube with an initial speed.

Le dévidoir, alors libre par rapport à la torpille, bascule. Mais étant toujours relié à cette dernière par le mécanisme de liaison, il se trouve tracté tant que la contrainte de séparation n'est pas atteinte.The reel, then free compared to the torpedo, rocking. But still being connected to it by the link mechanism, it is pulled as long as the separation constraint is not reached.

Le moteur de la torpille se met en route, l'ensemble torpille et dévidoir s'éloigne du sous-marin. Ainsi le câble liant le dévidoir au sous-marin se déploie.The engine of the torpedo starts, the whole torpedo and reel moves away from the submarine. Thus the cable linking the reel to the submarine unfolds.

Lorsque le câble est complètement déployé, l'effort sur le mécanisme de liaison exercé par la torpille devient supérieur à la limite de rupture, le dévidoir est alors solidaire du sous-marin par l'intermédiaire du câble. La contrainte de séparation est atteinte, l'ensemble gaine et dévidoir se sépare donc de la torpille.When the cable is fully deployed, the force on the connecting mechanism exerted by the torpedo becomes greater than the breaking limit, the reel is then secured to the submarine via the cable. The separation stress is reached, the sheath and reel assembly is separated from the torpedo.

Il s'ensuit une période d'instabilité pendant laquelle le dévidoir se positionne quille en bas en retrait par rapport à la brèche dans l'orifice du bordé de l'étrave. En fin de positionnement, sa position est fonction de l'angle d'incidence de l'axe de son plan fixe avec l'axe du vecteur vitesse et la valeur de celui-ci. Ainsi le point de dévidage se trouve éloigné du sous-marin, le dévidoir ne risque pas de venir heurter ce dernier.There follows a period of instability during which the reel is positioned keel down recessed from the breach in the opening of the plating of the stem. At the end of positioning, its position is a function of the angle of incidence of the axis of its fixed plane with the axis of the velocity vector and the value thereof. Thus the reeling point is far from the submarine, the reel is not likely to come up against the latter.

La torpille s'éloigne du dévidoir en dévidant le fil contenu dans cette dernière, laissant ainsi derrière elle un fil immobile dans le fluide car du fil se déroule également depuis la bobine contenue dans le dévidoir. Ce dernier, solidaire du sous-marin par le câble, a une trajectoire stabilisée.The torpedo moves away from the reel by unwinding the wire contained therein, leaving behind a wire motionless in the fluid because the wire is also unwound from the reel contained in the reel. The latter, secured to the submarine by the cable, has a stabilized trajectory.
