L'invention concerne une arme à feu automatique multitubes de petit ou moyen calibre du typeThe invention relates to a small or medium caliber multitube automatic firearm of the type
GATLING, notamment destinée au tir de munitions télescopées, comprenant au moins un système d'alimentation en munitions et un système de chargement et de tir à plusieurs chambres, arme dans laquelle le système de chargement et de tir est logé à l'intérieur d'un corps ou corps de l'arme et comprend un bloc de chargement qui est monté mobile en rotation autour d'un arbre central fixe et qui est solidaire en rotation des tubes de l'arme, et dans laquelle chaque chambre, au cours d'une rotation complète du bloc de chargement, passe d'une position de chargement où la chambre est ouverte et latéralement décalée par rapport aux tubes de l'arme pour pouvoir y charger une munition, à une posi¬ tion de tir où la chambre est fermée et axialement ali- gnée avec l'un des tubes de l'arme pour pouvoir procéder au tir de la munition, ladite chambre étant guidée au cours de son déplacement par des moyens de guidage.GATLING, especially intended for firing telescoped munitions, comprising at least one ammunition supply system and a multi-chamber loading and firing system, weapon in which the loading and firing system is housed inside a body or body of the weapon and comprises a loading block which is mounted mobile in rotation around a fixed central shaft and which is integral in rotation with the tubes of the weapon, and in which each chamber, during a complete rotation of the loading block, passes from a loading position where the chamber is open and laterally offset with respect to the barrel of the weapon so as to be able to load ammunition therein, at a firing position where the chamber is closed and axially aligned with one of the barrels of the weapon in order to be able to fire the ammunition, said chamber being guided during its movement by guide means.
Le domaine de l'invention est généralement celui des armes à feu automatiques de petit ou moyen calibre à cadence de tir élevée, de l'ordre de 1000 coups par minute et par tube, qui sont notamment utilisées pour une défense rapprochée antimissiles.The field of the invention is generally that of automatic firearms of small or medium caliber with a high rate of fire, of the order of 1000 rounds per minute and per tube, which are in particular used for close missile defense.
D'une manière générale, le système de chargement et de tir dans une arme automatique multitubes utilisant des munitions classiques, comprend une culasse mobile qui ferme l'extrémité arrière d'une chambre de chargement au moment du tir. Après le tir, la culasse est ouverte pour extraire, par l'arrière de la chambre, la douille de la munition tirée. Etant donné qu'une munition télescopée se présente sous la forme d'un corps allongé à profil extérieur constant généralement cylindrique, cette forme cylindrique est avantageusement mise à profit notamment dans des armes à feu à un seul tube et à chambre pivotante, pour éjecter automatiquement, par l'avant de la chambre, la douille d'une munition précédemment tirée qui est poussée au fur et à mesure du chargement d'une nouvelle munition dans la chambre. Un tel avantage pourrait donc être également mis à profit dans une arme à feu automatique multitubes du type GATLING pour simplifier la structure du système de chargement et de tir. En effet, dans ce cas, il serait alors possible de supprimer la culasse mobile, comme cela est d'ailleurs envisagé dans le document US-A-3, 688, 637.Generally, the loading and firing system in a multi-tube automatic weapon using conventional ammunition, comprises a movable breech which closes the rear end of a loading chamber at the time of firing. After firing, the breech is opened to extract, from the rear of the chamber, the cartridge case of the fired ammunition. Since a telescoped munition is in the form of an elongated body with a generally cylindrical constant external profile, this form cylindrical is advantageously used in particular in firearms with a single tube and pivoting chamber, for automatically ejecting, from the front of the chamber, the casing of a previously fired ammunition which is pushed as and when loading of new ammunition in the room. Such an advantage could therefore also be taken advantage of in a multi-tube automatic firearm of the GATLING type to simplify the structure of the loading and firing system. Indeed, in this case, it would then be possible to remove the movable cylinder head, as is moreover envisaged in document US-A-3, 688, 637.
Dans ce document antérieur, le système de chargement et de tir comprend notamment plusieurs chambres reliées les unes aux autres de manière à former une chaîne articulée fermée. Cette chaîne s'enroule, vers une extrémité, sur un bloc rotatif étoile qui supporte également les tubes de l'arme, alors que la chaîne, vers son autre extrémité, est guidée par un chemin de came. En considérant le sens de rotation du bloc rotatif étoile, une chambre qui s'approche de ce bloc rotatif contient une munition à tirer, une chambre qui s'éloigne du bloc contient la douille de la munition précédemment tirée, et une chambre qui parcourt le chemin de came situé au-delà du bloc rotatif reçoit une nouvelle munition qui, au cours de son chargement, pousse et éjecte la douille précitée.In this prior document, the loading and firing system notably comprises several chambers connected to each other so as to form a closed articulated chain. This chain is wound, towards one end, on a rotary star block which also supports the tubes of the weapon, while the chain, towards its other end, is guided by a cam track. Considering the direction of rotation of the star rotary block, a chamber which approaches this rotary block contains a munition to be fired, a chamber which moves away from the block contains the socket of the ammunition previously fired, and a chamber which traverses the cam path located beyond the rotary block receives new ammunition which, during its loading, pushes and ejects the aforementioned sleeve.
Cependant, un tel système de chargement et de tir est conçu avec un nombre de chambres supérieur à celui des tubes de l'arme. Il en résulte un bloc de chargement et de tir relativement volumineux présentant une masse importante qui nécessite un organe moteur approprié pour vaincre l'inertie du bloc de chargement.However, such a loading and firing system is designed with a number of chambers greater than that of the barrel of the weapon. This results in a relatively bulky loading and firing block having a large mass which requires an appropriate drive member to overcome the inertia of the loading block.
Le but de l'invention est de pallier les inconvénients précités et elle propose à cet effet une arme à feu automatique multitubes de petit ou moyen calibre du type précité, et qui est caractérisée en ce que chaque chambre de l'arme est montée pivotante autour d'un tirant solidaire du bloc de chargement du système de chargement et de tir, et est liée fonctionnellement à un tube de l'arme, et en ce que les moyens de guidage des chambres sont constitués d'une came interne fixe supportée par ledit arbre central et d'une came externe fixe prévue à la surface interne du corps de 1 'arme et qui entoure la came interne en étant séparée de celle-ci d'une distance constante correspondant sensiblement au diamètre externe des chambres.The object of the invention is to overcome the aforementioned drawbacks and to this end it proposes a small or medium multi-barrel automatic firearm caliber of the aforementioned type, and which is characterized in that each chamber of the weapon is pivotally mounted around a tie rod secured to the loading block of the loading and firing system, and is functionally linked to a tube of the weapon , and in that the guide means of the chambers consist of a fixed internal cam supported by said central shaft and of a fixed external cam provided on the internal surface of the body of the weapon and which surrounds the internal cam being separated from the latter by a constant distance corresponding substantially to the external diameter of the chambers.
Le nombre des chambres de chargement est égal à celui de tubes de l'arme, ce nombre étant compris entre 2 et 8 (nombre maximum usuel) . D'une manière générale, chaque chambre est constituée d'un corps cylindrique dont la périphérie supporte deux bossages axialement alignés et percés chacun d'une ouverture pour le libre passage du tirant associé à cette chambre. Selon un mode de réalisation de l'invention, la came interne fixe est par exemple constituée par deux disques supportés par l'arbre central fixe et séparés l'un de l'autre d'une distance inférieure à la longueur des chambres, chaque disque définissant à sa périphérie un chemin de came autour de l'arbre central fixe de support en rotation du bloc de chargement du système de chargement et de tir.The number of loading chambers is equal to that of the barrel of the weapon, this number being between 2 and 8 (usual maximum number). Generally, each chamber consists of a cylindrical body whose periphery supports two axially aligned bosses each pierced with an opening for the free passage of the tie rod associated with this chamber. According to one embodiment of the invention, the fixed internal cam is for example constituted by two discs supported by the fixed central shaft and separated from each other by a distance less than the length of the chambers, each disc defining at its periphery a cam path around the fixed central shaft for rotating support of the loading block of the loading and firing system.
Selon un exemple de réalisation de l'invention, la came externe est par exemple constituée par deux nervures formées sur la paroi interne du corps de l'arme et séparées l'une de l'autre d'une distance inférieure à la longueur des chambres, chaque nervure définissant par son bord d'extrémité libre un chemin de came qui entoure l'un des disques de la came interne fixe précitée. D'une manière générale, les deux cames fixes interne et externe délimitent quatre zones dans lesquelles chaque chambre passe successivement au cours d'une rotation complète du bloc de chargement du système de chargement et de tir autour de l'axe central précité :According to an exemplary embodiment of the invention, the external cam is for example constituted by two ribs formed on the internal wall of the body of the weapon and separated from each other by a distance less than the length of the chambers , each rib defining by its free end edge a cam path which surrounds one of the discs of the above-mentioned fixed internal cam. Generally, the two internal and external fixed cams delimit four zones into which each chamber passes successively during a complete rotation of the loading block of the loading and firing system around the aforementioned central axis:
- par une zone de chargement dans laquelle la chambre est ouverte et décalée latéralement par rapport au tube associé de l'arme pour recevoir une munition,- by a loading area in which the chamber is open and offset laterally relative to the associated barrel of the weapon to receive ammunition,
- par une zone de fermeture dans laquelle la chambre se ferme progressivement en se rapprochant du tube associé,- by a closing zone in which the chamber gradually closes while approaching the associated tube,
- par une zone de tir dans laquelle la chambre est axialement alignée avec le tube associé de l'arme, et- by a firing zone in which the chamber is axially aligned with the associated barrel of the weapon, and
- par une zone d'ouverture dans laquelle la chambre s'ouvre progressivement en s'écartant du tube associé.- by an opening zone in which the chamber gradually opens away from the associated tube.
Ainsi, chaque chambre est liée fonctionnellement à l'un des tubes de l'arme et à un tirant, les moyens de guidage faisant pivoter chaque chambre autour de son tirant associé suivant un cycle défini par les moyens de guidage.Thus, each chamber is functionally linked to one of the gun's tubes and to a tie rod, the guide means making each chamber pivot around its associated tie rod according to a cycle defined by the guide means.
Selon une autre caractéristique de l'invention, le bloc de chargement du système de chargement et de tir est logé à l'intérieur du corps de l'arme, monté en arrière des chambres de chargement par rapport à la direction de tir de l'arme et comprend à sa périphérie des goulottes s'étendant parallèlement à l'arbre central fixe, régulièrement réparties autour dudit bloc pour recevoir des munitions et coopérant avec une rampe hélicoïdale fixe prévue sur la paroi interne du corps de l'arme pour déplacer en translation les munitions en direction des chambres au cours de la rotation du bloc de chargement.According to another characteristic of the invention, the loading block of the loading and firing system is housed inside the body of the weapon, mounted behind the loading chambers relative to the firing direction of the weapon and comprises at its periphery troughs extending parallel to the fixed central shaft, regularly distributed around said block for receiving ammunition and cooperating with a fixed helical ramp provided on the internal wall of the body of the weapon to move in translation the ammunition in the direction of the chambers during the rotation of the loading block.
En fonctionnement, l'une des goulottes du bloc de chargement est axialement alignée avec l'une des chambres lorsque cette dernière se déplace dans la zone de chargement précitée délimitée par les cames fixes interne et externe.In operation, one of the chutes of the loading block is axially aligned with one of the chambers when the latter moves in the area of the above loading delimited by the internal and external fixed cams.
Selon une autre caractéristique de l'invention, le système d'alimentation en munitions comprend une ouverture latérale d'entrée prévue dans le corps de l'arme et située au niveau du bloc de chargement, cette ouverture d'entrée s'étendant parallèlement à l'arbre central fixe précité et sur une longueur au moins égale à celle d'une munition, cette ouverture permettant le passage des munitions, une à une, entre un magasin d'alimentation et les goulottes de réception du bloc de chargement.According to another characteristic of the invention, the ammunition supply system comprises a lateral entry opening provided in the body of the weapon and located at the level of the loading block, this entry opening extending parallel to the aforementioned fixed central shaft and over a length at least equal to that of a munition, this opening allowing the passage of the ammunition, one by one, between a feed store and the chutes for receiving the loading block.
Pour tenir compte du recul de l'arme consécutif au tir d'une munition, la longueur de l'ouverture d'entrée située au niveau du bloc de chargement s'étend sur une longueur supérieure à celle d'une munition.To take account of the retreat of the weapon following the firing of a munition, the length of the entry opening located at the level of the loading block extends over a length greater than that of a munition.
Selon une autre caractéristique de l'invention, l'arme comprend également un système d'éjection des douilles des munitions tirées, ce système étant logé dans le corps de l'arme, situé en avant des chambres en considérant la direction de tir de l'arme et comprenant un bloc monté rotatif autour de l'axe central fixe précité. Selon une autre caractéristique de l'invention, le bloc d'éjection comprend à sa périphérie des moyens de support des douilles, l'un de ces supports étant axialement aligné avec celle des chambres située dans la zone de chargement précitée délimitée par les cames fixes interne et externe.According to another characteristic of the invention, the weapon also comprises a system for ejecting the casings of the ammunition fired, this system being housed in the body of the weapon, located in front of the chambers by considering the firing direction of weapon and comprising a block rotatably mounted around the aforementioned fixed central axis. According to another characteristic of the invention, the ejection block comprises at its periphery means for supporting the sockets, one of these supports being axially aligned with that of the chambers located in the aforementioned loading area delimited by the fixed cams internal and external.
Selon un exemple de réalisation de l'invention, le bloc d'éjection est constitué de deux roues étoilées solidaires de l'arbre central fixe précité, munies d'encoches et séparées l'une de l'autre d'une distance inférieure à la longueur d'une douille, deux encoches axialement alignées des deux roues étoilées formant un support de réception d'une douille poussée par une nouvelle munition introduite dans la chambre qui est située dans la zone de chargement délimitée par les cames fixes interne et externe. Selon une autre caractéristique de l'invention, le système d'éjection comprend également une ouverture latérale de sortie prévue dans le corps de l'arme et située au niveau du bloc d'éjection, cette ouverture de sortie s'étendant parallèlement à l'axe central fixe précité et sur une longueur au moins égale à celle d'une douille, et un levier fixe pour éjecter une douille à l'extérieur lors de son passage devant ladite ouverture de sortie.According to an exemplary embodiment of the invention, the ejection block consists of two star wheels secured to the above-mentioned fixed central shaft, provided with notches and separated from each other by a distance less than the length of a socket, two axially aligned notches of the two star wheels forming a support for receiving a socket pushed by a new munition introduced into the chamber which is located in the loading area delimited by the internal and external fixed cams. According to another characteristic of the invention, the ejection system also comprises a lateral outlet opening provided in the body of the weapon and located at the level of the ejection block, this outlet opening extending parallel to the aforementioned fixed central axis and over a length at least equal to that of a socket, and a fixed lever for ejecting a socket outside when it passes in front of said outlet opening.
Les tirants qui supportent les chambres assurent la cohésion de l'ensemble tournant de l'arme, cet ensemble comprenant notamment le bloc de chargement, les chambres, les tubes et le système d'éjection. Ces tirants s'étendent parallèlement à l'arbre central fixe de l'arme, et le nombre des chambres peut être éventuellement inférieur au nombre des tirants.The tie rods which support the chambers ensure the cohesion of the rotating assembly of the weapon, this assembly notably comprising the loading block, the chambers, the tubes and the ejection system. These tie rods extend parallel to the fixed central shaft of the weapon, and the number of chambers may possibly be less than the number of tie rods.
D'une manière générale, la chambre proprement dite qui reçoit une munition télescopée peut avoir une section droite circulaire ou une section droite polygonale, par exemple carrée, pour tirer des munitions télescopées ayant une forme correspondante.In general, the chamber proper which receives a telescoped munition can have a circular cross section or a polygonal cross section, for example square, for firing telescoped munitions having a corresponding shape.
Selon un avantage important de l'invention, chaque chambre de chargement est associée à un tube de l'arme et à un tirant, ce qui permet de concevoir un bloc de chargement compact et dont la masse, le volume et le moment d'inertie autour de l'axe de rotation de l'arme sont réduits.According to an important advantage of the invention, each loading chamber is associated with a gun barrel and with a tie rod, which makes it possible to design a compact loading block whose mass, volume and moment of inertia around the axis of rotation of the weapon are reduced.

L'arme 1 selon l'invention est telle que schématiquement représentée à la figure 1, est une arme à feu automatique multitubes de petit ou moyen calibre du type GATLING et à cadence de tir élevée, qui est notamment conçue pour le tir de munitions télescopées. Dans l'exemple illustré sur les figures 1 et- Figure 9 is a sectional view similar to Figure 7 but according to an alternative embodiment of the invention, and Figure 10 is a sectional view corresponding to Figure 8 according to the variant illustrated in Figure 9. The weapon 1 according to the invention is as shown diagrammatically in FIG. 1, is a multi-tube automatic firearm of small or medium caliber of the GATLING type and with a high rate of fire, which is in particular designed for firing telescoped munitions. In the example illustrated in Figures 1 and
2, cette arme 1 comprend un système SA d'alimentation en munitions, un système SC de chargement et de tir, et un système SE d'éjection des douilles des munitions tirées.2, this weapon 1 comprises a system SA for supplying ammunition, a system SC for loading and firing, and a system SE for ejecting the casings of the munitions fired.
L'arme 1 comprend un corps fixe creux 3, de forme allongée et dont une extrémité ou extrémité arrière est fermée par un fond 5. Trois logements 7, 8 et 9 successifs sont délimités à 1 'intérieur du corps 3 de l'arme entre son fond 5 et son autre extrémité.The weapon 1 comprises a hollow fixed body 3, of elongated shape and one end or rear end of which is closed by a bottom 5. Three housings 7, 8 and 9 successive are delimited inside the body 3 of the weapon between its bottom 5 and its other end.
En se reportant aux figures 1, 4 et 5, le système SC de chargement et de tir comprend un bloc de chargement 10 qui est monté rotatif dans le logement 7 du corps 3 de l'arme autour d'un arbre central fixe 12 au moyen de paliers 14. Le bloc de chargement 10 est de forme globalement cylindrique et comporte, à sa périphérie, des empreintes formant des goulottes 16 de réception des munitions M. Les goulottes 16 s'étendent chacune sur toute la longueur du bloc de chargement 10 et sont régulièrement réparties autour de ce bloc 10. Les munitions M réceptionnées dans les goulottes 16 coopèrent avec une rampe hélicoïdale fixe 18 formée sur la paroi interne du logement 7 du corps 3 de l'arme, de manière à pouvoir déplacer également en translation les munitions dans les goulottes 16 au cours de la rotation du bloc de chargement 10.Referring to Figures 1, 4 and 5, the SC loading and firing system comprises a loading block 10 which is rotatably mounted in the housing 7 of the body 3 of the weapon around a fixed central shaft 12 by means of bearings 14. The loading block 10 is of generally cylindrical shape and comprises, at its periphery, indentations forming troughs 16 for receiving ammunition M. The troughs 16 each extend over the entire length of the loading block 10 and are regularly distributed around this block 10. The munitions M received in the chutes 16 cooperate with a fixed helical ramp 18 formed on the internal wall of the housing 7 of the body 3 of the weapon, so as to be able to also move the ammunition in translation in the troughs 16 during the rotation of the loading block 10.
En se reportant aux figures 1, 2, 6 et 7, le système SC de chargement et de tir comprend plusieurs chambres 20, par exemple au nombre de quatre. Chaque chambre 20 (figure 6) est constituée d'un corps cylindrique allongé 22 percé d'un canal central 24 qui forme la chambre proprement dite destinée à recevoir une munition M. Le corps 22 de chaque chambre 20 comporte à sa périphérie deux bossages 26 en saillie, axialement alignés et percés chacun d'une ouverture 28 pour le libre passage d'un tirant 30 autour de laquelle la chambre 20 associée est montée pivotante. Les chambres 20 peuvent être avantageusement constituées en un matériau composite (enroulé filamentaire) .Referring to Figures 1, 2, 6 and 7, the loading and firing system SC comprises several chambers 20, for example four in number. Each chamber 20 (FIG. 6) consists of an elongated cylindrical body 22 pierced with a central channel 24 which forms the chamber proper intended to receive ammunition M. The body 22 of each chamber 20 has at its periphery two bosses 26 projecting, axially aligned and each pierced with an opening 28 for the free passage of a tie rod 30 around which the associated chamber 20 is pivotally mounted. The chambers 20 can advantageously be made of a composite material (filament wound).
Les quatre chambres 20 et les quatre tirants 30 associés sont montés dans le logement 8 du corps 3 de l'arme, en étant régulièrement disposés autour de l'arbre central fixe 12 et parallèlement à ce dernier. Les tirants 30 sont solidaires en rotation du bloc de chargement 10 monté dans le logement 7 du corps 3 de l'arme.The four chambers 20 and the four associated tie rods 30 are mounted in the housing 8 of the body 3 of the weapon, being regularly arranged around the fixed central shaft 12 and parallel to the latter. The tie rods 30 are integral in rotation with the block of load 10 mounted in the housing 7 of the body 3 of the weapon.
Les chambres 20, au cours de la rotation du bloc de chargement 10, sont guidées entre deux cames fixes respectivement interne 32 et externe 34 séparées l'une de l'autre d'une distance constante correspondant au diamètre externe des chambres 20.The chambers 20, during the rotation of the loading block 10, are guided between two fixed cams respectively internal 32 and external 34 separated from each other by a constant distance corresponding to the external diameter of the chambers 20.
La came interne fixe 32 est par exemple constituée de deux disques 32a solidaires de l'arbre central fixe 12 et séparés l'un de l'autre d'une distance inférieure à la longueur des chambres 20.The fixed internal cam 32 is for example made up of two discs 32a secured to the fixed central shaft 12 and separated from each other by a distance less than the length of the chambers 20.
La came fixe externe 34 est par exemple constituée de deux nervures 34a en saillie sur la paroi interne du logement 8 et séparées l'une de l'autre d'une distance inférieure à la longueur des chambres 20. Chaque nervure 34a entoure un disque 32a et est située sensiblement en regard de ce dernier.The external fixed cam 34 is for example made up of two ribs 34a projecting from the internal wall of the housing 8 and separated from each other by a distance less than the length of the chambers 20. Each rib 34a surrounds a disc 32a and is located substantially opposite the latter.
Ainsi, les cames 32 et 34 délimitent entre elles deux chemins de came interne et externe qui guident les chambres 20 au cours de la rotation du bloc de chargement 10 et définissent quatre zones successives s'étendant sur 360* :Thus, the cams 32 and 34 delimit between them two internal and external cam paths which guide the chambers 20 during the rotation of the loading block 10 and define four successive zones extending over 360 * :
- une zone de chargement ZC où une première chambre 20 est ouverte et décalée latéralement par rapport au tube T associé de l'arme pour pouvoir y charger une munition,a loading zone ZC where a first chamber 20 is open and offset laterally relative to the associated tube T of the weapon in order to be able to load a munition there,
- une zone de fermeture ZF où une seconde chambre 20 contenant une munition passe de sa position ouverte à sa position fermée en se rapprochant du tube T associé, une zone de tir ZT où une troisième chambre 20 est fermée et axialement alignée avec le tube T associé de l'arme, eta ZF closing zone where a second chamber 20 containing an ammunition passes from its open position to its closed position by approaching the associated tube T, a ZT firing zone where a third chamber 20 is closed and axially aligned with the tube T weapon partner, and
- une zone d'ouverture ZO où la quatrième chambre 20 passe de sa position de fermeture à sa position d'ouverture en s'écartant du tube T associé. Un ressort 35 à deux lames 36 et 37 est monté sur chaque tirant 30 entre les deux bossages 26 de la chambre 20 associée. Vers une extrémité, la lame 36 du ressort 35 prend appui sur l'arbre central fixe 12, alors que vers son autre extrémité, la lame 37 du ressort 35 prend appui sur le corps 22 de la chambre 20. La fonction de ces ressorts 35 sera explicitée plus loin.- An opening zone ZO where the fourth chamber 20 passes from its closed position to its open position away from the associated tube T. A spring 35 with two blades 36 and 37 is mounted on each tie rod 30 between the two bosses 26 of the associated chamber 20. Towards one end, the blade 36 of the spring 35 bears on the fixed central shaft 12, while towards its other end, the blade 37 of the spring 35 bears on the body 22 of the chamber 20. The function of these springs 35 will be explained later.
Le système SA d'alimentation en munitions est schématiquement représenté aux figures 1 et 4. Ce système SA d'alimentation comprend une ouverture latérale 38 prévue dans le corps 3 de l'arme au niveau du bloc de chargement 10. Cette ouverture d'entrée 38 s'étend parallèlement aux goulottes 16 du bloc de chargement 10 et sur une longueur supérieure à celle d'une munition pour tenir compte du mouvement de recul de l'arme consécutif au tir d'une munition. Le système SA d'alimentation comprend un magasin externe (non représenté) et des moyens pour déverser en continu les munitions par l'ouverture d'entrée 38 qui sont ensuite réceptionnées par les goulottes 16 du bloc de chargement 10 au cours de la rotation de ce dernier.The system SA for supplying ammunition is schematically represented in FIGS. 1 and 4. This system SA for supply comprises a lateral opening 38 provided in the body 3 of the weapon at the level of the loading block 10. This entry opening 38 extends parallel to the chutes 16 of the loading block 10 and over a length greater than that of a munition to take account of the recoil movement of the weapon following the firing of an ammunition. The SA supply system comprises an external magazine (not shown) and means for continuously discharging the ammunition through the inlet opening 38 which are then received by the chutes 16 of the loading block 10 during the rotation of this last.
En se reportant aux figures 1 et 8, le système SE d'éjection des douilles des munitions tirées à partir des chambres de chargement 20, comprend un bloc d'éjection 40 situé dans le logement 9 du corps 3 de l'arme et monté rotatif autour de l'arbre central fixe 12. Ce bloc d'éjection 40 est supporté en rotation par les tirants 30 qui traversent de part en part le bloc 40, ainsi que les quatre tubes T de l'arme. Le bloc 40 comporte à sa périphérie des goulottes 42 de réception des douilles. Ces goulottes 42 s'étendent parallèlement à l'arbre central fixe 12 et sont régulièrement réparties autour du bloc d'éjection 40. Le système SE d'éjection est complété par une ouverture latérale de sortie 44 située au niveau du bloc d'éjection 40. Cette ouverture de sortie 44 s'étend parallèlement aux goulottes 42 et sur une longueur au moins égale à celle d'une douille. Un dispositif éjecteur fixe 45 situé au niveau de cette ouverture de sortie 44 assure l'éjection des douilles hors des goulottes 42 à leur passage devant cette ouverture 44.Referring to FIGS. 1 and 8, the system SE for ejecting the casings of the ammunition fired from the loading chambers 20, comprises an ejection block 40 located in the housing 9 of the body 3 of the weapon and rotatably mounted around the fixed central shaft 12. This ejection block 40 is rotatably supported by the tie rods 30 which pass right through the block 40, as well as the four tubes T of the weapon. The block 40 has at its periphery troughs 42 for receiving the sockets. These chutes 42 extend parallel to the fixed central shaft 12 and are regularly distributed around the ejection block 40. The SE ejection system is completed by a lateral outlet opening 44 located at the level of the ejection block 40 This outlet opening 44 extends parallel to the chutes 42 and over a length at least equal to that of a socket. A fixed ejector device 45 situated at the level of this outlet opening 44 ejects the sockets from the troughs 42 as they pass in front of this opening 44.
Une variante de réalisation du système SE d'éjection des douilles est schématiquement illustrée à la figure 1. Selon cette variante, le bloc d'éjection est constitué par deux roues étoilées 46 solidaires en rotation des tirants 30. Les deux roues étoilées 46 sont séparées l'une de l'autre d'une distance inférieure à la longueur d'une douille.A variant embodiment of the SE ejection system for the sockets is schematically illustrated in FIG. 1. According to this variant, the ejection block is constituted by two star wheels 46 integral in rotation with the tie rods 30. The two star wheels 46 are separated from each other by a distance less than the length of a socket.
Quatre dispositifs de percussion 50 sont logés à l'intérieur du bloc de chargement 10 et sont respectivement associés aux quatre chambres 20. Lorsqu'une chambre 20 entre dans la zone de tir ZT délimitée par les deux cames 32 et 34, un dispositif de commande 52 (figure 1) libère le dispositif de percussion 50 associé à cette chambre 20 pour qu'il vienne percuter l'amorce de la munition. Ce dispositif de commande 52, situé sur la paroi de fond 5 du corps 3 de l'arme, comprend par exemple un levier articulé qui maintient le dispositif de percussion 50 dans un état armé tant que la chambre 20 n'est pas entrée dans la zone de tir ZT. Ce levier supporte un galet qui roule sur une came dont le chemin comporte un décrochement qui, au passage du galet, permet de dégager le levier et libérer ainsi le dispositif de percussion 50. Cette percussion du type mécanique pourrait être remplacée par une initiation électrique ou par induction suivant le type de munition utilisé.Four percussion devices 50 are housed inside the loading block 10 and are respectively associated with the four chambers 20. When a chamber 20 enters the firing zone ZT delimited by the two cams 32 and 34, a control device 52 (FIG. 1) releases the percussion device 50 associated with this chamber 20 so that it comes into impact with the primer of the munition. This control device 52, located on the bottom wall 5 of the body 3 of the weapon, for example comprises an articulated lever which maintains the percussion device 50 in an armed state until the chamber 20 has not entered the ZT shooting area. This lever supports a roller which rolls on a cam, the path of which includes a recess which, when the roller passes, allows the lever to be released and thus releases the percussion device 50. This percussion of the mechanical type could be replaced by an electrical initiation or by induction depending on the type of ammunition used.
Le logement 9 dans lequel est monté le système d'éjection SE des douilles est fermé par une pièce 55 qui supporte également les tirants 30 ainsi que les tubes T qui se prolongent au-delà de cette pièce 55 solidaire en rotation du bloc de chargement 10 (figure 1) . En se reportant à la figure 2, un organe moteur externe M, tel qu'un moto-réducteur, a un arbre de sortie qui supporte un pignon d'entraînement 56 qui vient engrener une denture 58 prévue à la périphérie de la pièce de support 55 pour entraîner en rotation l'ensemble tournant de l'arme comprenant le bloc de chargement 10, les tirants 30 et les chambres 20 associées, les tubes T et le bloc d'éjection 40. Il est important de noter que les tirants 30 assurent la cohésion de cet ensemble tournant mobile en rotation autour de l'arbre central fixe 12.The housing 9 in which the SE ejection system of the sockets is mounted is closed by a part 55 which also supports the tie rods 30 as well as the tubes T which extend beyond this part 55 integral in rotation with the loading block 10 (figure 1) . Referring to Figure 2, an external motor member M, such as a gear motor, has an output shaft which supports a drive pinion 56 which engages a toothing 58 provided at the periphery of the support piece 55 to rotate the rotating assembly of the weapon comprising the loading block 10, the tie rods 30 and the associated chambers 20, the tubes T and the ejection block 40. It is important to note that the tie rods 30 provide the cohesion of this rotating assembly which rotates around the fixed central shaft 12.
En se reportant à la figure 7, une butée d'arrêt 60, de forme arquée, est montée pivotante autour d'un pion 62 supporté par le corps 3 de l'arme. Cette butée 60 est située en avant des chambres 20 et dans la zone de chargement ZC. La butée 60 vient obstruer en partie l'extrémité avant de la chambre 20 située dans la zone de chargement ZC pour arrêter la première munition en cours de chargement, cette butée 60 étant ensuite relevée et maintenue relevée par les douilles des munitions tirées.Referring to Figure 7, a stopper 60, of arcuate shape, is pivotally mounted around a pin 62 supported by the body 3 of the weapon. This stop 60 is located in front of the chambers 20 and in the loading area ZC. The stop 60 partially obstructs the front end of the chamber 20 located in the loading zone ZC to stop the first ammunition during loading, this stop 60 is then raised and kept raised by the sockets of the fired ammunition.
Les figures 9 et 10 illustrent une variante de réalisation dans le cas de munitions télescopées ayant une forme carrée par exemple. Dans ce cas, le système d'alimentation SA (figure 10) est complété par des leviers 70 destinés à faciliter la réception des munitions dans les goulottes 16 du bloc de chargement 10, ces goulottes ayant alors une section carrée. Chaque levier 70, à raison d'un levier par goulotte 16, est monté pivotant à une extrémité autour d'un tirant 30, alors que son autre extrémité se termine par un crochet 72 de positionnement. Les quatre leviers 70 sont régulièrement répartis autour du bloc de chargement 10 et pivote sous la commande d'un bossage 74a d'une came centrale 74 associée à quatre tiges 76. La came centrale 74 est fixe et supportée par l'arbre central fixe 12 de l'arme, et les quatre tiges 76 sont montées coulissantes à l'intérieur de * passages radiaux ménagés dans le bloc de chargement 10. Chaque tige 76 prend ainsi appui sur la came centrale 74 et sur le levier 70 associé, de manière à faire pivoter ce dernier radialement vers l'extérieur lorsque la tige 76 prend appui sur le bossage 74a de la came centrale 74, c'est-à- dire au moment où le crochet 72 du levier 70 est en regard de l'ouverture d'entrée 38 pour prendre appui sur la nouvelle munition M qui entre par l'ouverture 38 et orienter correctement cette munition M lors de sa réception dans la goulotte 16 associée au levier 70.Figures 9 and 10 illustrate an alternative embodiment in the case of telescoped ammunition having a square shape for example. In this case, the supply system SA (FIG. 10) is completed by levers 70 intended to facilitate the reception of the ammunition in the troughs 16 of the loading block 10, these troughs then having a square section. Each lever 70, at the rate of one lever per chute 16, is pivotally mounted at one end around a tie rod 30, while its other end ends in a positioning hook 72. The four levers 70 are regularly distributed around the loading block 10 and pivots under the control of a boss 74a of a central cam 74 associated with four rods 76. The central cam 74 is fixed and supported by the central shaft fixed 12 of the weapon, and the four rods 76 are slidably mounted inside * radial passages formed in the loading block 10. Each rod 76 thus bears on the central cam 74 and on the associated lever 70, so as to pivot the latter radially outward when the rod 76 bears on the boss 74a of the central cam 74, that is to say when the hook 72 of the lever 70 is opposite the opening inlet 38 to rest on the new munition M which enters through the opening 38 and correctly orient this ammunition M when it is received in the chute 16 associated with the lever 70.
On va décrire ci-après le fonctionnement de 1 'arme. Lorsque l'organe moteur M est actionné :The operation of the weapon will be described below. When the drive unit M is activated:
- le bloc de chargement 10 est entraîné en rotation autour de l'arbre central fixe 12,the loading block 10 is rotated around the fixed central shaft 12,
- les tirants 30, solidaires en rotation du bloc de chargement 10, sont entraînés en rotation autour de l'arbre central fixe 12, de sorte que les chambres 20 supportées par les tirants 30 se déplacent entre les cames fixes interne 32 et externe 34, les tubes T de l'arme, solidaires en rotation du bloc de chargement 10, sont entraînés en rotation autour de l'arbre central fixe 12, etthe tie rods 30, integral in rotation with the loading block 10, are rotated around the fixed central shaft 12, so that the chambers 20 supported by the tie rods 30 move between the internal fixed 32 and external fixed cams 34, the tubes T of the weapon, integral in rotation with the loading block 10, are driven in rotation around the fixed central shaft 12, and
- le bloc d'éjection 40, solidaire en rotation du bloc de chargement 10, est également entraîné en rotation autour de l'arbre central fixe 12.the ejection block 40, integral in rotation with the loading block 10, is also driven in rotation around the fixed central shaft 12.
Les munitions extraites du magasin d'alimentation sont déversées en continu par l'ouverture d'entrée 38 du corps 3 de l'arme. Dès qu'une goulotte 16 du bloc de chargement 10 passe devant l'ouverture d'entrée 38, elle réceptionne une munition dont le culot prend appui sur la rampe hélicoïdale fixe 18. Le mouvement de rotation du bloc de chargement 10 et la rampe hélicoïdale fixe 18 provoquent un mouvement de O 96/36845 PCÏ7FR95/00665The ammunition extracted from the supply magazine is continuously discharged through the inlet opening 38 of the body 3 of the weapon. As soon as a chute 16 of the loading block 10 passes in front of the inlet opening 38, it receives an ammunition whose base is supported on the fixed helical ramp 18. The rotational movement of the loading block 10 and the helical ramp fixed 18 cause movement of O 96/36845 PCÏ7FR95 / 00665
14 translation des munitions en direction des chambres de chargement 20. Lorsqu'une chambre 20 entre dans la zone de chargement ZC et se déplace tout au long de cette zone, cette chambre est ouverte et se trouve axialement alignée avec l'une des goulottes 16 du bloc de chargement 10. Une munition est ainsi progressivement chargée dans la chambre 20 et est complètement chargée lorsqu'elle vient au contact de la butée d'arrêt située à l'avant de la chambre 20. Une fois chargée, la chambre 20 entre dans la zone de fermeture ZF où le décalage latéral avec le tube T associé de l'arme diminue progressivement. La chambre 20 entre ensuite dans la zone de tir ZT où elle est axialement alignée avec le tube T associé de l'arme. Le percuteur P est actionné et la munition est tirée. La chambre 20 qui contient la douille de la munition tirée entre ensuite dans la zone d'ouverture ZO où elle se décale à nouveau progressivement par rapport au tube T associé. Ensuite, lorsque la chambre 20 entre à nouveau dans la zone de chargement ZC, la nouvelle munition qui est chargée dans la chambre 20 pousse progressivement la douille de la munition précédemment chargée. Lorsque la chambre 20 parcourt la zone de chargement ZC, elle est axialement alignée avec une goulotte 42 du bloc d'éjection rotatif 40 qui réceptionne ainsi la douille qui est ensuite éjectée par l'ouverture de sortie 44.14 translation of the ammunition in the direction of the loading chambers 20. When a chamber 20 enters the loading zone ZC and moves throughout this zone, this chamber is open and is axially aligned with one of the troughs 16 of the loading block 10. A munition is thus progressively loaded into the chamber 20 and is fully charged when it comes into contact with the stopper located at the front of the chamber 20. Once loaded, the chamber 20 enters in the ZF closing zone where the lateral offset with the associated T-tube of the weapon gradually decreases. The chamber 20 then enters the firing zone ZT where it is axially aligned with the associated tube T of the weapon. The striker P is activated and the ammunition is fired. The chamber 20 which contains the cartridge case of the fired ammunition then enters the opening zone ZO where it again gradually shifts relative to the associated tube T. Then, when the chamber 20 re-enters the loading zone ZC, the new ammunition which is loaded in the chamber 20 gradually pushes the casing of the previously loaded ammunition. When the chamber 20 traverses the loading area ZC, it is axially aligned with a chute 42 of the rotary ejection block 40 which thus receives the sleeve which is then ejected through the outlet opening 44.
A chaque cycle correspondant à une rotation complète du bloc de chargement 10, une première chambre 20 parcourt la zone de chargement ZC par exemple, une seconde chambre 20 parcourt la zone de fermeture ZF, une troisième chambre 20 parcourt la zone de tir ZT et la quatrième chambre 20 parcourt la zone d'ouverture ZO, et ainsi de suite.At each cycle corresponding to a complete rotation of the loading block 10, a first chamber 20 traverses the loading zone ZC for example, a second chamber 20 traverses the closing zone ZF, a third chamber 20 traverses the firing zone ZT and the fourth bedroom 20 runs through the opening zone ZO, and so on.
Les ressorts 35 associés aux chambres 20 ont pour fonction de limiter les efforts de frottement des chambres 20 sur la came externe 34 et de vaincre la force centrifuge appliquée aux chambres 20 lors de la rotation du bloc de chargement 10.The springs 35 associated with the chambers 20 have the function of limiting the friction forces of the chambers 20 on the external cam 34 and of overcoming the force centrifugal applied to the chambers 20 during the rotation of the loading block 10.
Les cycles de chargement et de tir se succèdent pour tirer une rafale à cadence élevée, les quatre tubes T de l'arme tirant successivement une munition au cours d'une rotation complète du système SC de chargement et de tir, sachant que la position où a lieu la percussion est identique pour tous les tubes T de l'arme. The loading and firing cycles follow one another to fire a burst at high rate, the four T tubes of the weapon successively firing ammunition during a complete rotation of the SC loading and firing system, knowing that the position where the percussion takes place is identical for all the T tubes of the weapon.
