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. 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. The technical sector of the invention is that of devices for unwinding a wire ensuring the transmission of information of all kinds (orders or reports) between two mobiles moving in a fluid. One of the main applications of the invention is its use for filotransmission 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 not reliable. The transmission link through a cable or wire overcomes 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 within a reduced perimeter, the cables used are generally bulky, fixed on the mobile and run from the launcher 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 has to move within a large perimeter, whatever its speed, or if the two mobile move simultaneously in independent tracks from each other, it is necessary to use cables of small section which simultaneously unwind from the moving mobiles, so each mobile leaves behind a motionless wire in the fluid, and the efforts are markedly 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 current torpedoes which move at various speeds - over a long distance while being controlled by the building which launched them.
Dans ce domaine, plusieurs réalisations ont déjà été proposées.Several projects have already been proposed in this area.
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. 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 coil of the launcher building is positioned in a locked container at the bottom of the torpedo tube. The wire, which unwinds from it, is protected by a sheath to avoid breaks due to friction and possible snagging with the projecting parts of the tube. This protective sheath deploys during the first meters of the torpedo's journey by being driven by it. The sheath is ballasted to move away from the launcher, however it has been observed that with the increase in the speed of the submarine, it tends to approach it so much that the wire unwinds along the hull and risks being caught by the current of water induced by the propeller, which is liable to cause it to 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. 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 current design of the French container also has the consequence of limiting the size of the reel and therefore the length of wire carried by the submarine, which reduces its ability to evolve during the wire-guiding phase. French-designed submarines launch their torpedoes by means of telescopic cylinders, called "pneumatic pushers"; the pushing force is exerted on the rear of the torpedo. To date, it has always been possible to offset the exit of the wire on one of the control surfaces of the weapon so that the repressor exerts no pressure force on the sheath or the wire. However, the new internal equipment of the torpedoes limits the space on the periphery and no longer allows this solution to be applied, which means that the wire outlet must be positioned 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. 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. 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.In the same technical field, the patent filed under the number FR 2 654 204 is known, which describes a device for unwinding the filotransmission cable of a machine moving at high speed in a fluid. The cable is stored in the form of a coil integrated in an existing volume around a fairing secured to the launched mobile, it takes place on demand as a function of the movement of the latter. One end of the cable is integral with the launched mobile, it corresponds to the winding layer of smaller diameter. The other end, connected to the container, takes place from the larger diameter layer. Thus the cable unrolls by sliding on the back of the structure by forming a tapered helical curve closing behind the mobile launched, at the same time the wire also unrolls from the reel 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 linked to the latter 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 drawbacks linked 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.Due to 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 risks hitting the hull of the submarine and thus disturbing the monitoring performed 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 lies in the size of the container which limits the length of wire on the side of the submarine and therefore reduces its capacity for evolution. The wire length 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 remedy the above drawbacks by proposing a device for unwinding a transmission wire 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. Un autre but de l'invention est de réaliser un dispositif ayant une trajectoire stabilisée dans le fluide.The present invention also aims to provide a device which removes the unwinding point from the launcher shell. 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 propose a device increasing the development capabilities of the submarine 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. Les moyens de stabilisation du dévidoir comportent, de préférence, une quille combinée à un plan fixe.To do this, the invention relates to a device for unwinding a wire ensuring the transmission of information of all kinds (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, device characterized in that the reel, separable from the two mobiles, comprises means for stabilizing the latter in the fluid. The reel stabilization means 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 launching.
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. 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.A connection mechanism can temporarily ensure the connection between the reel and the mobile launched. It can consist of a spring-loaded ball system with tared separation constraint. The device may include a short protective sheath where the wire unwinds, connected to the connection mechanism by one of its ends.
Le dévidoir comporte, de préférence, une ou deux bobines . 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. 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. Cet élément est constitué, de préférence, d'une rondelle en mousse souple disposée entre le dévidoir et le refouloir pneumatique.The reel preferably has one or two coils. Preferably, if it has two reels, a thread tension regulating mechanism makes it possible to transfer the unwinding action from the first reel to the second, eliminating the shock caused by variations in the length of the transfer loop. An element associated with the reel can make it possible to compensate for the clearances between the last named and the end of the pneumatic reel to avoid the shock at the start of deployment of the latter. This element preferably consists of a flexible foam washer placed between the reel and the pneumatic reel.
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 simultaneous launching of the torpedo and the reel comprising the wire reel (s). The unwinding point is thus located 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 coming into contact with 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. 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 also has the advantage of moving the reeling point away from the submarine, which constitutes protection against potential aggressions due to turbulence near the hull. The device advantageously offers a large capacity for the development of the submarine by having the possibility of having two spools in the reel and therefore allowing faster reeling of the wire, since it is not possible for it to complete its reeling before the end of its connection with the torpedo.
D'autres caractéristiques et avantages de l'invention apparaîtront dans la description détaillée, non limitative, ci-dessous .Other characteristics and advantages of the invention will appear in the detailed, non-limiting description, 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.Referring to Figures 1 to 7 we see a device for unwinding a transmission wire 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) comprising one or two spools of wire (15) and (16). Before launching, this reel is placed between a launching mechanism, called a pneumatic repressor (4), and a torpedo (1), inside a launching tube (6) of the launcher building (7). Other launch modes, such as launching by pumped water or launching by self-starting, are possible, this implies modifications to the 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 centralizer (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) . 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. 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) .A flexible sheath (10), in which a wire is unwound (8), connects one of the faces of the reel to the torpedo by a connecting mechanism (9). The latter is based, for example, on a mechanical ball-on-spring system comprising a tared separation constraint, identical to the existing solution (any other separation system is possible). A foam washer (19) is placed between the pneumatic reel and the reel, to compensate for the play 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 secured to the pneumatic presser, but a rigid foam can also be used, in this case the washer will be destroyed at each launch and will necessarily be secured to the reel. The reel is connected by a cable (5) to a housing (3) integral with the launcher tube. This cable, ensuring the transmission of information to the submarine, is connected to the spool 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. 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 thrust spacer (12), placed in the axis of the reel, makes it possible to transmit the forces of the pneumatic repressor to the torpedo during the launching 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. 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 latter. In the case where the reel has two reels, the wire is continuous. To transfer the unwinding of the thread from one reel to the other without causing a jerk, a thread tension regulating mechanism (13) makes it possible to compensate for the relaxation of the thread at the end of unwinding of the first reel by playing on the relaxation of a spring. The wire is then guided by a pulley system and the spring ensures the constant 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 launching, the pneumatic repressor exerts a force on the thrust spacer integral with the reel, which in turn pushes the torpedo until the first named is fully deployed. 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 relative to the torpedo, tilts. But being always linked to the latter by the linking mechanism, it is pulled until the separation constraint is 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 torpedo engine starts, the torpedo and reel assembly moves away from the submarine. Thus the cable connecting the reel to the submarine is deployed.
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 connection mechanism exerted by the torpedo becomes greater than the breaking limit, the reel is then secured to the submarine via the cable. The separation constraint is reached, the sheath and reel assembly therefore separates 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. 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. There follows a period of instability during which the reel is positioned keel down, set back with respect to the breach in the orifice of the plating of the bow. 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 speed vector and the value thereof. Thus the reeling point is located far from the submarine, the reel is not likely to strike the latter. The torpedo moves away from the reel by unwinding the wire contained in the latter, thus leaving behind a wire immobile in the fluid because wire also unwinds from the coil contained in the reel. The latter, secured to the submarine by the cable, has a stabilized trajectory.
