Description

La présente invention concerne un navire comportant au moins un puits de réception d'au moins un conteneur de lancement de missile.The present invention relates to a vessel comprising at least one receiving well of at least one missile launching container.

On connaît déjà dans l'état de la technique, des navires équipés de tels conteneurs choisis par exemple dans la gamme des conteneurs connus sous la marque SYLVER ® de la demanderesse.In the state of the art, vessels equipped with such containers, for example chosen from the range of containers known under the trademark SYLVER® from the applicant, are already known.

Dans les systèmes connus, le ou chaque conteneur de lancement est reçu dans un ou des puits correspondants du navire de manière que leur partie supérieure affleure le pont du navire et que leur partie inférieure soit fixée rigidement au fond du puits et donc à la structure du navire.In the known systems, the or each launching container is received in one or more corresponding wells of the ship so that their upper part is flush with the deck of the ship and their lower part is fixed rigidly to the bottom of the well and thus to the structure of the ship.

Or ceci présente un certain nombre d'inconvénients notamment au niveau de la protection des missiles ou de façon générale des munitions dans le ou chaque conteneur car les chocs que subit le navire sont transmis intégralement aux munitions stockées dans les conteneurs.However this has a number of disadvantages including the protection of missiles or generally ammunition in the or each container because the shocks suffered by the ship are transmitted integrally to the ammunition stored in the containers.

Ceci est par exemple le cas lors d'explosions sous-marines qui peuvent se traduire par des chocs de plusieurs dizaines de g dans la structure du navire.This is for example the case with submarine explosions that can result in shocks of several tens of g in the structure of the ship.

D'une façon générale, on connaît dans l'état de la technique par le document FR 2 559 863 , un support résilient à seuil, notamment pour la suspension de dispositifs ou matériels sur des navires.In general, the state of the art is known from the document FR 2,559,863 , a resilient threshold support, especially for the suspension of devices or equipment on ships.

Un tel support comporte un élément de support en forme de U, en matériau résilient, dont l'une des branches est fixée à la structure porteuse telle que le navire et dont l'autre branche supporte le dispositif ou matériel, les deux branches étant rigidifiées par une entretoise s'étendant entre celles-ci, formée par une tige fracturable dans un plan sensiblement parallèle aux branches du U et reliée aux deux branches, la liaison avec l'une au moins desdites branches étant assurée par un second élément fracturable dans la direction de la tige.Such a support comprises a U-shaped support element of resilient material, one of whose branches is attached to the supporting structure such as the ship and the other branch supports the device or material, the two branches being stiffened. by a spacer extending between them, formed by a fracturable rod in a plane substantially parallel to the branches of the U and connected to the two branches, the connection with at least one of said branches being provided by a second fracturable element in the direction of the stem.

Cependant un tel support n'est pas transposable dans la présente application en raison des contraintes spécifiques évoquées précédemment.However, such a support is not transposable in the present application because of the specific constraints mentioned above.

On notera par ailleurs que des systèmes de suspension élastiques sont également décrits dans les documents EP 0 304 345 et GB 2 160 825 .Note also that elastic suspension systems are also described in the documents EP 0 304 345 and GB 2,160,825 .

L'invention sera mieux comprise à l'aide de la description qui va suivre donnée à titre d'exemple et faite en se référant aux dessins annexés sur lesquels :

  • la figure 1 représente une vue en perspective d'un conteneur de lancement de missile équipé de moyens d'amortissement;
  • les figures 2 et 3 représentent des vues partielles en perspective de la partie supérieure de ce conteneur en position dans un puits de réception d'un navire;
  • la figure 4 représente une vue en perspective à échelle agrandie des moyens d'amortissement équipant la partie inférieure du conteneur représenté sur les figures précédentes;
  • la figure 5 représente une vue de côté de ces moyens d'amortissement; et
  • la figure 6 représente une vue de détail d'une barrette à seuil de rupture entrant la constitution de ces moyens d'amortissement.
The invention will be better understood with the aid of the following description given by way of example and with reference to the appended drawings in which:
  • the figure 1 represents a perspective view of a missile launching container equipped with damping means;
  • the Figures 2 and 3 represent partial perspective views of the upper part of this container in position in a receiving well of a ship;
  • the figure 4 is a perspective view on an enlarged scale of the damping means equipping the lower part of the container shown in the previous figures;
  • the figure 5 represents a side view of these damping means; and
  • the figure 6 represents a detailed view of a bar with breaking threshold entering the constitution of these damping means.

On a en effet illustré sur ces figures 1 à 3, un conteneur de lancement de missile qui est désigné par la référence générale 1 sur ces figures et qui est reçu dans un puits de réception correspondant 2 d'un navire 3.We have indeed illustrated on these Figures 1 to 3 , a missile launching container which is designated by the general reference 1 in these figures and which is received in a corresponding receiving well 2 of a ship 3.

Dans l'exemple de réalisation illustré, le conteneur et le puits présentent des axes verticaux, la partie supérieure du conteneur affleurant par exemple le pont du navire et étant munie d'une trappe de fermeture désignée par la référence générale 4, escamotable lors du tir d'un missile.In the exemplary embodiment illustrated, the container and the well have vertical axes, the upper part of the container flush for example the deck of the vessel and being provided with a closure door designated by the general reference 4, retractable when firing. of a missile.

Comme cela est également illustré, de façon classique, ces missiles sont par exemple reçus dans le conteneur 1 avec leurs alvéoles ou capsules de protection dont l'une est par exemple désignée par la référence générale 5.As is also illustrated, conventionally, these missiles are for example received in the container 1 with their cells or protective caps, one of which is for example designated by the general reference 5.

En fait et comme cela est illustré sur ces figures, le conteneur de lancement 1 est reçu avec un débattement axial et latéral contrôlé dans le puits et la paroi latérale de ce conteneur est munie, dans sa partie supérieure, de moyens de centrage/guidage dans le puits, formés par exemple par des butées en matériau d'amortissement dont l'une est visible sur ces figures et désignée par la référence générale 6.In fact and as illustrated in these figures, the launch container 1 is received with a controlled axial and lateral displacement in the well and the side wall of this container is provided, in its upper part, with centering / guiding means in the well, formed for example by abutments of damping material, one of which is visible in these figures and designated by the general reference 6.

Ces butées en matériau d'amortissement sont alors par exemple disposées entre le conteneur et la paroi correspondante du puits pour centrer et guider par exemple la partie supérieure de ce conteneur dans ce puits.These abutments in damping material are then for example disposed between the container and the corresponding wall of the well to center and guide for example the upper part of this container in the well.

Dans sa partie inférieure le conteneur est associé et repose sur des moyens amortisseurs désignés par la référence générale 7 sur la figure 1, comportant une semelle porte-conteneur désignée par la référence générale 8 associée à une semelle d'appui du navire désignée par la référence générale 9, à travers des moyens d'amortissement à seuil de filtration de choc désignés par la référence générale 10.In its lower part the container is associated and rests on damping means designated by the general reference 7 on the figure 1 , having a sole Container carrier designated by the general reference 8 associated with a bearing plate of the ship designated by the general reference 9, through damping means with shock filtration threshold designated by the general reference 10.

Ces moyens d'amortissement seront décrits plus en détails sur les figures 4, 5 et 6.These damping means will be described in more detail on the figures 4 , 5 and 6 .

En fait et comme cela est illustré, ces moyens d'amortissement comprennent au moins un ensemble amortisseur à spires métalliques et dans l'exemple illustré au moins deux ensembles amortisseurs à spires métalliques, disposés symétriquement de part et d'autre du conteneur et désignés par les références générales 11 et 12 sur ces figures.In fact and as illustrated, these damping means comprise at least one damping assembly with metal turns and in the illustrated example at least two damping assemblies with metal turns, arranged symmetrically on either side of the container and designated by the general references 11 and 12 in these figures.

En fait, les ensembles amortisseurs à spires se présentent par exemple sous la forme d'au moins un organe à ressort hélicoïdal disposé en position allongée entre les semelles et dont les bords opposés sont engagés dans des trous de passage de traverses de liaison correspondantes des semelles telles que par exemple les traverses 13, 14, 15 et 16 illustrées sur ces figures.In fact, the coil damping assemblies are, for example, in the form of at least one helical spring member disposed in an extended position between the soles and whose opposite edges are engaged in holes for the passage of the corresponding connecting ties of the soles. such as for example the crosspieces 13, 14, 15 and 16 illustrated in these figures.

Ces moyens d'amortissement comportent également des barrettes à seuil de rupture montées sous précontrainte entre les deux semelles dont deux respectivement 17 et 18 sont illustrées sur ces figures.These damping means also comprise break-off bars mounted under prestressing between the two flanges of which two respectively 17 and 18 are illustrated in these figures.

L'une de ces barrettes de rupture 18 est illustrée plus en détail sur la figure 6.One of these rupture bars 18 is illustrated in more detail on the figure 6 .

Cette barrette de rupture comporte alors deux portions de barrette respectivement 19 et 20 raccordées par une goupille frangible 21 et dont chaque extrémité est associée à une semelle.This rupture bar then comprises two bar portions respectively 19 and 20 connected by a breakable pin 21 and each end of which is associated with a sole.

Ainsi par exemple chaque barrette comporte une portion de barrette mâle désignée par la référence générale 20, dont une extrémité est adaptée pour s'engager dans une chape 22 d'une extrémité d'une portion de barrette femelle 19 correspondante, la goupille frangible 21 s'étendant transversalement dans la chape 22 de la portion de barrette femelle 19 et à travers la portion de barrette mâle 20.For example, each bar has a male bar portion designated by the general reference 20, one end of which is adapted to engage in a clevis 22 of one end of a corresponding female bar portion 19, the breakable pin 21 extending transversely in the yoke 22 of the female bar portion 19 and through the male bar portion 20.

Comme cela est également visible sur cette figure 6, au moins une extrémité de chaque barrette 18 est filetée et est engagée dans un trou de passage respectivement 23, 24 d'une patte de fixation 25, 26 sur la semelle correspondante 8, 9 et coopère avec un écrou correspondant 27, 28 pour permettre le montage sous précontrainte de cette barrette entre les semelles.As is also visible on this figure 6 at least one end of each bar 18 is threaded and is engaged in a through hole 23, 24 respectively of a fastening tab 25, 26 on the corresponding sole 8, 9 and cooperates with a corresponding nut 27, 28 to allow the fitting under prestressing of this bar between the soles.

Dans l'exemple de réalisation illustré, les deux extrémités de chaque barrette sont filetées et chacune de celles-ci est adaptée pour être engagée dans un trou d'une patte de fixation et pour coopérer avec un écrou correspondant.In the exemplary embodiment illustrated, the two ends of each bar are threaded and each of these is adapted to be engaged in a hole of a fixing lug and to cooperate with a corresponding nut.

On notera également que chaque écrou présente une portée d'appui sphérique respectivement 29 et 30, adaptée pour coopérer avec une surface d'appui complémentaire de la patte correspondante 25, 26.It will also be noted that each nut has a spherical bearing surface 29 and 30, respectively, adapted to cooperate with a complementary bearing surface of the corresponding tab 25, 26.

Les moyens d'amortissement à seuil peuvent comporter plusieurs barrettes à seuil de rupture associées.The threshold damping means may comprise several bars with associated break point.

Ainsi par exemple au moins deux barrettes à seuil de rupture associées et montées tête-bêche entre les semelles, peuvent être envisagées.Thus, for example, at least two strips with associated breaking threshold and mounted head to tail between the flanges can be envisaged.

Celles-ci sont avantageusement inclinées en direction de l'axe du conteneur 1 comme cela est visible sur ces figures.These are advantageously inclined towards the axis of the container 1 as can be seen in these figures.

En fait et selon le mode de réalisation représenté, les moyens d'amortissement peuvent comporter deux jeux de deux barrettes disposés symétriquement de part et d'autre du conteneur.In fact and according to the embodiment shown, the damping means may comprise two sets of two bars arranged symmetrically on either side of the container.

C'est ainsi que dans l'exemple illustré, le conteneur présente une section rectangulaire et deux ensembles amortisseurs à spires métalliques sont disposés symétriquement sur deux côtés de celui-ci, tandis que deux jeux de deux barrettes sont disposés symétriquement sur les deux autres côtés de celui-ci.Thus, in the illustrated example, the container has a rectangular section and two metal coil damping assemblies are arranged symmetrically on two sides thereof, while two sets of two bars are arranged symmetrically on the other two sides. of it.

Une telle structure permet par exemple à partir d'un choc d'entrée de 30 g en vertical ou de 15 g en transversal, d'absorber l'énergie de choc pour obtenir un maximum de 10 g sur la munition embarquée, avec un chargement de munitions variable de 1 à 4 munitions c'est-à-dire une évolution de la masse des munitions de 150 à 600 kilos, un chargement de munitions dissymétrique ou encore une prise en compte de l'effort lié au départ d'un missile (35 KN dissymétrique au lanceur) en sachant qu'en conditions normales d'utilisation (tir de départ missile, mouvements de la plateforme, etc...), les axes des alvéoles de lancement doivent respecter une fidélité de position de l'ordre 1,5 mrad.Such a structure makes it possible, for example, from an input shock of 30 g vertically or 15 g transversely, to absorb shock energy to obtain a maximum of 10 g on the onboard munition, with a loading ammunition variable from 1 to 4 ammunition that is to say an evolution of the ammunition mass from 150 to 600 kilos, a loading of asymmetric ammunition or taking into account the effort related to the departure of a missile (35 KN dissymmetrical to the launcher) knowing that under normal conditions of use (missile firing, platform movements, etc ...), the axes of the launching cells must respect a position fidelity of the order 1.5 mrad.

Ainsi, on intègre un ensemble amortisseur avec un seuil de déclenchement dans la fixation du conteneur/lanceur sur le navire.Thus, it incorporates a damper assembly with a trigger in the fastener container / launcher on the ship.

En conditions normales d'utilisation, le lanceur conserve ses caractéristiques de raideur pour satisfaire les exigences d'alignement des missiles et en cas de chocs liés par exemple à des explosions sous-marines, les amortisseurs se déclenchent aux valeurs de calibrage.Under normal conditions of use, the launcher retains its stiffness characteristics to meet the missile alignment requirements and in the event of shocks related for example to underwater explosions, the shocks are triggered at the calibration values.

Ceci permet de limiter les accélérations au niveau des munitions afin de les préserver.This makes it possible to limit ammunition accelerations in order to preserve them.

Comme cela a été indiqué précédemment, les barrettes sont montées avec une précontrainte au niveau des moyens d'amortissement.As indicated above, the bars are mounted with a prestressing at the damping means.

Dans ces conditions, les barrettes sont en extension et résistent aux efforts générés par l'écrasement des amortisseurs.In these conditions, the bars are in extension and resist the forces generated by the crashing of the dampers.

En cas de choc lié par exemple à une explosion sous-marine, la mise en mouvement du lanceur du bas vers le haut, provoque un écrasement supplémentaire des spires.In the event of an impact related for example to an underwater explosion, the movement of the launcher from the bottom to the top causes an additional crushing of the turns.

A cet instant les barrettes ne sont plus en tension. C'est au retour du choc, lorsque les barrettes se remettent en place que la rupture des barrettes frangibles s'effectue.At this moment the bars are no longer in tension. It is at the return of the shock, when the bars are put back in place that the rupture of the frangible bars is carried out.

Ce sont ensuite les amortisseurs qui prennent le relais pour protéger les munitions.It is then the dampers that take over to protect the ammunition.

En cas de choc transversal, les efforts appliqués sur le lanceur provoquent un couple au niveau des barrettes. Les deux barrettes qui travaillent en compression sont rompues à la première impulsion de choc, les deux autres étant cassées au premier retour du choc.In case of transverse impact, the forces applied to the launcher cause a torque at the bars. The two bars that work in compression are broken at the first shock pulse, the other two being broken at the first shock return.

Les amortisseurs prennent ensuite le relais pour filtrer les accélérations et préserver les munitions.The shock absorbers then take over to filter the accelerations and preserve the ammunition.

Ce principe permet de diviser par deux les accélérations du choc vertical soit 15 g.This principle makes it possible to halve the accelerations of the vertical shock, ie 15 g.

On notera qu'après un choc d'explosion sous-marine alors que les barrettes se sont rompues, il est possible de reconfigurer l'installation pour que le lanceur retrouve sa capacité nominale, en remplaçant simplement les barrettes.It will be noted that after an underwater explosion shock while the bars have broken, it is possible to reconfigure the installation for the launcher returns to its nominal capacity, simply replacing the bars.

On conçoit alors que ces moyens d'amortissement avec un seuil de déclenchement permettent de limiter les contraintes lors des calculs de dimensionnement du lanceur.It is then conceivable that these damping means with a tripping threshold make it possible to limit the constraints during launcher design calculations.

Ceci permet non seulement de réduire d'une manière générale la tenue mécanique du lanceur mais également de réduire les efforts aux interfaces navire et aux interfaces munitions.This not only reduces the overall mechanical strength of the launcher but also reduces the efforts at ship interfaces and ammunition interfaces.

Il va de soi bien entendu que d'autres modes de réalisation encore peuvent être envisagés.It goes without saying of course that other embodiments can be envisaged.
