Description

Le secteur technique de la présente invention est celui des dispositifs d'alimentation d'une arme.The technical sector of the present invention is that weapons supply devices.

Pour alimenter une arme de gros ou moyen calibre, il est bien connu d'utiliser soit un chargement manuel à l'aide d'une civière et dans ce cas il est possible de charger des munitions unitaires ou des munitions en fardeaux (projectile et charges modulaires) soit des moyens automatiques permettant de prélever uniquement des munitions unitaires à partir d'un magasin. Toutefois lorsque l'arme se trouve dans un espace confiné ou isolé comme par exemple sur un navire, il n'est pas concevable de manipuler avec les moyens classiques les charges modulaires et les projectiles. En effet, la masse des projectiles est très importante et dépasse les capacités d'un opérateur d'une part et le risque pyrotechnique devient trop important puisqu'un incident peut conduire à la destruction de l'ensemble et donc la perte d'un navire d'autre part.To feed a large or medium caliber weapon, it is well known to use either manual loading at using a stretcher and in this case it is possible to load unit ammunition or ammunition in burdens (projectile and modular charges) or means automatic allowing to take only unit ammunition from a store. However when the weapon is in a confined or isolated space like for example on a ship, it is not conceivable to handle modular loads with conventional means and projectiles. Indeed, the mass of the projectiles is very important and exceeds the capabilities of an operator on the one hand and the pyrotechnic risk becomes too important since an incident can lead to destruction of the whole and therefore the loss of a ship on the other hand.

Le but de la présente invention est de fournir un dispositif de chargement automatique d'une arme de gros ou moyen calibre montée sur une structure isolée telle un navire offrant un très haut niveau de sécurité.The object of the present invention is to provide a automatic loading device for a large weapon or medium caliber mounted on an isolated structure such as a ship offering a very high level of security.

L'invention a donc pour objet un dispositif de chargement d'une arme de moyen ou de gros calibre alimentée en munitions constituées d'un projectile et de charges modulaires, caractérisé en ce qu'il comprend un moyen de réception d'un projectile et des charges modulaires, un véhicule comportant au moins deux logements, et des moyens support aptes à permettre le passage du véhicule d'une position initiale de garnissage à une position finale de chargement de l'arme dans laquelle le logement du projectile puis le logement des charges modulaires sont amenés successivement dans ladite position.The invention therefore relates to a device for loading of a medium or large caliber weapon supplied ammunition consisting of a projectile and charges modular, characterized in that it comprises a means of reception of a projectile and modular charges, a vehicle comprising at least two housings, and means support suitable for allowing the passage of the vehicle from initial packing position to a final position of loading of the weapon in which the housing of the projectile then the housing of modular charges are successively brought into said position.

Avantageusement, les moyens support sont constitués par une cage présentant deux flancs entre lesquels circule le véhicule.Advantageously, the support means are constituted by a cage with two sides between which the vehicle.

Avantageusement encore, le moyen de réception d'un projectile et des modules de charge est constitué par un conteneur se présentant sous la forme d'un élément tubulaire muni de moyens de retenue du projectile et des charges modulaires.Advantageously also, the means for receiving a projectile and charge modules consists of a container in the form of an element tubular provided with means for retaining the projectile and modular loads.

Selon une réalisation, le véhicule est constitué d'un chariot et d'un barillet se présentant sous la forme d'une pièce sensiblement parallélépipédique munie de logements au niveau de ses arêtes parallèles destinés à recevoir chacun un conteneur et le barillet peut comporter quatre logements disposés suivant quatre arêtes parallèles entre elles.According to one embodiment, the vehicle consists of a carriage and a barrel in the form of a substantially parallelepipedal part provided with housings at level of its parallel edges intended to receive each a container and the barrel can have four housings arranged along four edges parallel to each other.

La cage délimite un arc de cercle centré sur l'axe des tourillons de l'arme et elle comprend un chemin de roulement disposé sur chaque flanc, dans lesquels le chariot est monté par l'intermédiaire de galets.The cage delimits an arc centered on the axis of the weapon journals and it includes a path of bearing arranged on each side, in which the carriage is mounted by means of rollers.

Selon une autre réalisation, le barillet du véhicule est monté rotatif par rapport au chariot.According to another embodiment, the barrel of the vehicle is rotatably mounted relative to the carriage.

Selon encore une autre réalisation, le véhicule est mobile par rapport à la cage par l'intermédiaire d'un moteur solidaire du chariot engrainant sur une crémaillère solidaire de la cage.According to yet another embodiment, the vehicle is movable relative to the cage via a motor secured to the carriage driving on a rack secured to the cage.

Le véhicule peut supporter des moyens d'introduction du projectile puis des charges dans la chambre de l'arme.The vehicle can support means for introducing the projectile then charges in the chamber of the weapon.

Les moyens d'introduction sont représentés par un impulseur agissant sur le projectile et un refouloir agissant sur les charges modulaires.The means of introduction are represented by a impeller acting on the projectile and a repressor acting on modular loads.

Le barillet comporte des moyens de verrouillage des conteneurs.The barrel comprises means for locking the containers.

Selon encore une réalisation, les moyens de transfert sont solidaires de la tourelle pour transférer d'une part les conteneurs vides dans une réserve disposée à proximité et d'autre part prélever dans cette réserve des conteneurs pleins de projectiles et de charges modulaires.According to another embodiment, the transfer means are integral with the turret to transfer on the one hand empty containers in a nearby storage area and on the other hand take from this reserve containers full of projectiles and modular charges.

Un tout premier avantage du dispositif selon l'invention réside dans le haut niveau de sécurité obtenu puisque les projectiles et les charges modulaires ne sont jamais manipulés. En effet, durant toutes les phases de manipulation entre la réserve de projectiles et des charges modulaires et la chargement de l'arme c'est un élément de protection constitué par le conteneur qui subit toutes les contraintes. A very first advantage of the device according to the invention resides in the high level of security obtained since projectiles and modular charges are not never handled. Indeed, during all phases of manipulation between the projectile reserve and charges modular and loading the weapon is an element of protection constituted by the container which undergoes all constraints.

Un autre avantage réside dans la compacité du dispositif de chargement qui est placé très près de l'arme et intégrable dans une tourelle sans modification importante de celle-ci.Another advantage is the compactness of the loading device which is placed very close to the weapon and can be integrated into a turret without modification important of it.

Un autre avantage réside dans le fait que le dispositif de chargement assure une réversibilité du processus en cas d' incident.Another advantage is that the device loading ensures reversibility of the process in case incident.

D'autres caractéristiques, détails et avantages de l'invention ressortiront plus clairement de la description donnée ci-après à titre indicatif en relation avec des dessins dans lesquels :

  • la figure 1 est une vue montrant le véhicule et son support,
  • la figure 2 est une vue de dessus du barillet,
  • les figures 3 à 6 illustrent les différentes positions du barillet entre sa position initiale et sa position finale,
  • la figure 7 montre une tourelle équipée du dispositif selon l'invention.
Other characteristics, details and advantages of the invention will emerge more clearly from the description given below by way of indication in relation to the drawings in which:
  • FIG. 1 is a view showing the vehicle and its support,
  • FIG. 2 is a top view of the barrel,
  • FIGS. 3 to 6 illustrate the different positions of the barrel between its initial position and its final position,
  • Figure 7 shows a turret equipped with the device according to the invention.

Sur la figure 1 on a représenté une vue d'un véhicule 1 et des moyens support 2 définissant dans le plan de la figure une position initiale à une extrémité et une position finale quelconque entre la position initiale et l'autre extrémité. Le véhicule 1 visible sur la figure est représenté en position initiale et dans cette position il peut être garni de projectiles et de charges modulaires comme il sera expliqué ci-après. Le support 2 est une structure ajourée comprenant deux flancs latéraux 3 et 4 réunis par des poutres 5, munie à chaque extrémité d'un butoir inférieur 6 et d'un butoir supérieur 7. Ces butoirs permettent de limiter le déplacement du véhicule. Chaque flanc est muni d'une rainure. Sur la figure, on voit que la rainure 8 du flanc 3 est délimitée par une cornière en forme de U. Il en est de même de la rainure présente sur le flanc 4. Les moyens support présentent une forme générale préférée en arc de cercle et autrement dit le véhicule se déplace entre ses deux positions initiale et finale suivant un arc de cercle. Le véhicule 1 est donc mobile par rapport à son support 2 le long duquel il parcourt l'arc de cercle.In Figure 1 there is shown a view of a vehicle 1 and support means 2 defining in the plane of the figure an initial position at one end and a any final position between the initial position and the other extremity. The vehicle 1 visible in the figure is shown in the initial position and in this position it can be loaded with projectiles and modular charges as will be explained below. Support 2 is a openwork structure comprising two lateral sides 3 and 4 joined by beams 5, provided at each end with a lower bumper 6 and an upper bumper 7. These bumpers limit the movement of the vehicle. Each sidewall is provided with a groove. In the figure, we see that the groove 8 of the sidewall 3 is delimited by an angle in U shape. The same is true of the groove on the flank 4. The support means have a general shape preferred in an arc and in other words the vehicle moves between its two initial and final positions following an arc. Vehicle 1 is therefore movable relative to its support 2 along which it traverses the arc of a circle.

On a représenté sur la figure 2 une vue de dessus du véhicule 1 qui est composé deux parties, un chariot 9 et un barillet 10. Le chariot 9 se présente sous la forme générale d'une enveloppe fermée sur laquelle sont fixés quatre galets extérieurs 11a-11c qui coulissent dans les rainures 8 du support 2 afin que le véhicule parcourt le chemin en arc de cercle défini par les rainures 8. Le barillet 10 se présente sous la forme générale d'une pièce parallélépipédique munie d'un évidement 12 dans sa partie centrale. Dans celle-ci, on fixe un moteur 13 permettant d'entraíner en rotation le barillet 10 par rapport au chariot 9 suivant un axe perpendiculaire au plan de la figure et aligné suivant un rayon de l'arc de cercle. Le chariot 9 est entraíné par rapport au support 2 à l'aide d'un moteur non représenté en prise sur la crémaillère 61 et guidé par des galets 14. Dans l'évidement 12, on prévoit encore un impulseur 15 destiné à agir sur le projectile comme il sera expliqué ci-après. Le barillet 10 comprend quatre logements 16a-16d disposés suivant quatre arêtes parallèles entre elles. Deux logements 16a-16b sont représentés vides dans la moitié supérieure de la figure et deux logements 16c-16d sont pleins dans la moitié inférieure de la figure. Le logement 16c reçoit par exemple un conteneur 17 de modules de charge et le logement 16d un conteneur 18 de projectile. Un moyen de temporisation 19 est disposé au voisinage du conteneur 18 et dont le rôle est d'assurer la temporisation de la fusée présente sur le projectile. Un capteur 20 solidaire du chariot 9 permet de détecter un déchet éventuel du tir précédent dans le canon avant de commencer la nouvelle séquence de chargement. Sur la figure, on a encore représenté un refouloir 21 dont le rôle est d'introduire les modules de charge du conteneur 17 dans la chambre de l'arme.FIG. 2 shows a top view of the vehicle 1 which is composed of two parts, a carriage 9 and a barrel 10. The carriage 9 is in the form general of a closed envelope on which are fixed four outer rollers 11a-11c which slide in the grooves 8 of the support 2 so that the vehicle traverses the path in an arc defined by the grooves 8. The barrel 10 is in the general form of a coin rectangular with a recess 12 in its part Central. In it, a motor 13 is fixed allowing to rotate the barrel 10 relative to the carriage 9 along an axis perpendicular to the plane of the figure and aligned along a radius of the arc of a circle. The carriage 9 is driven relative to support 2 using an engine not shown engaged on the rack 61 and guided by rollers 14. In the recess 12, provision is made another impeller 15 intended to act on the projectile as will be explained below. Barrel 10 includes four housings 16a-16d arranged along four edges parallel to each other. Two housings 16a-16b are shown empty in the upper half of the figure and two slots 16c-16d are full in half lower of the figure. The housing 16c receives for example a container 17 of load modules and the housing 16d a projectile container 18. A timer 19 is arranged in the vicinity of the container 18 and whose role is to ensure the timing of the rocket present on the projectile. A sensor 20 secured to the carriage 9 allows detect any waste from the previous shot in the barrel before starting the new loading sequence. Sure in the figure, a repressor 21 is also shown, the role is to introduce the container load modules 17 in the gun room.

Les figures 3 à 6 illustrent les différentes phases de rotation du barillet 10 par rapport à son axe de rotation X sous l'action du moteur 13 et par rapport à l'axe Y de la chambre de l'arme. Sur la figure 3, le barillet 10 présente comme sur la figure 2 deux logements vides 16a et 16b et deux logements munis des modules de charge dans un conteneur 17 et d'un projectile dans un conteneur 18. Sur la figure 4, le véhicule 1 a été transféré de sa position initiale à sa position finale de chargement de l'arme. Durant cette phase, le barillet 10 subit une rotation de 1/6ème de tour par rapport au chariot 9 et le conteneur 18 de projectile est placé dans l'axe Y du canon au poste de refoulement. Le projectile peut alors être refoulé dans la chambre du canon, le conteneur étant maintenu dans le barillet par des moyens appropriés. Après refoulement du projectile et une nouvelle rotation de 1/6ème de tour du barillet 10 suivant la figure 5, les charges modulaires présentes dans le conteneur 17 se retrouvent suivant l'axe Y de la chambre et peuven t y être introduites à l'aide du refouloir 21a auquel est attaché le poussoir 21b, des moyens étant prévus pour maintenir le conteneur dans le barillet. Après refoulement des modules de charges et une nouvelle rotation de 1/6ème de tour suivant la figure 6, le barillet 10 n'est plus aligné avec l'axe Y du canon et il comporte deux logements vides 16a-16b et deux logements occupés par des conteneurs vides 17. On commande ensuite la descente du véhicule jusqu'à la position initiale. Dès que le barillet est alimenté à l'aide de conteneurs de projectile et de charges modulaires, le cycle précédemment décrit peut recommencer.Figures 3 to 6 illustrate the different phases of rotation of the barrel 10 relative to its axis of rotation X under the action of the motor 13 and relative to the axis Y of the chamber of the weapon. In FIG. 3, the barrel 10 has, as in FIG. 2, two empty housings 16a and 16b and two housings provided with charge modules in a container 17 and with a projectile in a container 18. In FIG. 4, the vehicle 1 has been transferred from its initial position to its final position for loading the weapon. During this phase, the barrel 10 undergoes a rotation of 1/6 th of a turn relative to the carriage 9 and the projectile container 18 is placed in the Y axis of the barrel at the delivery station. The projectile can then be forced back into the barrel chamber, the container being held in the barrel by appropriate means. After the projectile has been driven back and a new rotation of 1/6 th of a round of the barrel 10 according to FIG. 5, the modular charges present in the container 17 are found along the axis Y of the chamber and can be introduced using of the repressor 21a to which the pusher 21b is attached, means being provided for holding the container in the barrel. After pushing back the load modules and a new rotation of 1/6 th of a turn according to FIG. 6, the barrel 10 is no longer aligned with the axis Y of the barrel and it comprises two empty housings 16a-16b and two occupied housings by empty containers 17. The vehicle is then lowered to the initial position. As soon as the barrel is supplied with projectile containers and modular charges, the previously described cycle can start again.

La figure 7 permet de comprendre tout l'intérêt du dispositif selon l'invention. On suppose une tourelle 32 mobile en gisement suivant un circulaire 22 et supportant une arme 23 mobile en site par rapport à des tourillons 24 rotatifs par rapport à la tourelle. L'arme est du type 155 mm de 52 calibres et est alimentée par des projectiles et des modules de charges propulsives. Les deux fardeaux de la munition sont amenés à l'aide du dispositif selon l'invention à l'arrière de l'arme dans une position dite de chargement. Ce principe est connu et n'a pas à être explicité plus en détail. Le véhicule 1 monté sur le support 2 est intégré dans la tourelle et suivant une séquence entièrement automatisée amène les fardeaux de munitions jusqu'à la chambre du canon pour y être tirés. La mise à feu est réalisée classiquement à l'aide d'étoupilles stockées dans un barillet 25 disposé au niveau de la culasse de l'arme. Le véhicule 1 dans sa position inférieure coopère avec deux actionneurs 26 et 27, l'un 26 appelé élévateur pour prélever un conteneur de projectile et de modules dans une réserve 29 de stockage située en-dessous du circulaire 22 suivant un axe de ravitaillement, l'autre 27 appelé poussoir pour introduire les conteneurs vides dans la réserve de stockage. La tourelle 32 prend ensuite son pointage en gisement et arête son pointage en site suivant les instructions de tir reçues. Lorsque la culasse de l'arme 23 est ouverte, on commande le déplacement du véhicule 1 qui rallie l'arrière de l'arme. Pendant le ralliement, le moyen de temporisation 19 est descendu pour venir coiffer la fusée du projectile présent et aligné avec l'axe de refoulement. Lorsque la fusée est tempée, on dégage le moyen 19, on actionne ensuite le barillet 10 en rotation par rapport au chariot 9 d'un 6ème de tour pour amener le projectile tempé dans l'axe de refoulement comme représenté sur la figure 4. Dans sa position d'alignement avec l'axe de refoulement, le véhicule 1 est verrouillé sur le canon 23 afin d'éliminer tout mouvement relatif du véhicule par rapport à l'arme. On déverrouille le projectile par rapport à son conteneur et on déclenche l'impulseur 15 pour mettre à poste le projectile, c'est-à-dire l'amener au cône de forcement de la chambre de l'arme. On commande ensuite une rotation supplémentaire de 1/6ème de tour du barillet pour amener les modules de charge dans l'axe de refoulement Y, comme représenté sur la figure 5 et après avoir libéré les organes de maintien des modules dans leur conteneur on commande le refouloir 21 pour refouler ces modules. On commande une nouvelle rotation de 1/6ème de tour et le barillet 10 occupe alors la position représentée sur la figure 6. Le chariot 9 est alors déverrouillé du canon et on commande la descente du véhicule 1 vers sa position initiale représentée sur les figures 1 et 3.Figure 7 allows to understand the whole point of the device according to the invention. Suppose a turret 32 movable in bearing along a circular 22 and supporting a weapon 23 movable in elevation with respect to rotary pins 24 relative to the turret. The weapon is of the 155 mm type of 52 calibers and is powered by projectiles and propellant charge modules. The two burdens of the ammunition are brought using the device according to the invention to the rear of the weapon in a so-called loading position. This principle is known and need not be explained in more detail. The vehicle 1 mounted on the support 2 is integrated into the turret and according to a fully automated sequence brings the loads of ammunition to the barrel chamber to be fired there. The firing is carried out conventionally using pins stored in a barrel 25 disposed at the breech of the weapon. The vehicle 1 in its lower position cooperates with two actuators 26 and 27, one of which is called an elevator 26 for picking up a container of projectiles and modules from a storage reserve 29 located below the circular 22 along a supply axis, l another 27 called a pusher to introduce the empty containers into the storage reserve. The turret 32 then takes its pointing in deposit and stops its pointing in elevation according to the firing instructions received. When the breech of the weapon 23 is open, the movement of the vehicle 1 which joins the rear of the weapon is controlled. During the rallying, the timing means 19 is lowered to cover the rocket of the projectile present and aligned with the delivery axis. When the rocket is tempered, the means 19 are released, the barrel 10 is then actuated in rotation relative to the carriage 9 by a 6 th turn to bring the tempered projectile into the delivery axis as shown in FIG. 4. In its position of alignment with the delivery axis, the vehicle 1 is locked on the barrel 23 in order to eliminate any relative movement of the vehicle relative to the weapon. The projectile is unlocked relative to its container and the impeller 15 is triggered to position the projectile, that is to say bring it to the forcing cone of the chamber of the weapon. We then order an additional rotation of 1/6 th of a barrel turn to bring the load modules in the delivery axis Y, as shown in Figure 5 and after having released the modules holding members in their container we order the repressor 21 for repressing these modules. A new rotation of 1/6 th of a turn is ordered and the barrel 10 then occupies the position shown in FIG. 6. The carriage 9 is then unlocked from the barrel and the descent of the vehicle 1 is controlled to its initial position shown in the figures 1 and 3.

Il va sans dire que la tourelle 32 est mobile par rapport à son support représenté par exemple par une paroi 28 dans laquelle est pratiqué le circulaire 22. En dessous de cette paroi par exemple, on prévoit une réserve 29 de conteneurs de projectiles et de charges modulaires en quantité suffisante suivant la mission assignée. Bien entendu, la réserve 29 est positionnée de façon à ce que les actionneurs 26 et 27 puissent refouler les conteneurs vides et prélever des conteneurs pleins en combinaison avec cette réserve. Ainsi, on peut prévoir une réserve 29 comprenant des logements vides 30 dans lesquels les conteneurs vides sont introduits et des logements 31 pleins où les conteneurs sont prélevés. On a représenté une réserve présentant un alignement rectiligne des logements. Cette représentation est donnée à titre indicatif et on pourrait prévoir un alignement suivant deux cercles concentriques.It goes without saying that the turret 32 is movable by relative to its support represented for example by a wall 28 in which circular 22 is made. Below of this wall for example, a reserve 29 of containers for projectiles and modular charges in sufficient quantity according to the assigned mission. Well heard, the reserve 29 is positioned so that the actuators 26 and 27 can push the containers back empty and collect full containers in combination with this reservation. Thus, one can provide a reserve 29 comprising empty housings 30 in which the empty containers are introduced and 31 full receptacles where the containers are taken. We have represented a reserve having a straight alignment of the housings. This representation is given for information only and could provide alignment in two circles concentric.
