Description
Dispositif d'alimentation en cartouches pour une tourelle et procédé de chargement en cartouches d'un tel dispositif Le domaine technique de 1 ' invention est celui des dispositifs d'alimentation en cartouches pour une tourelle équipée d'un système d'arme. A turret cartridge feeding device and method of loading such a device into cartridges The technical field of the invention is that of the cartridge supply devices for a turret equipped with a weapon system.
Il est classique de doter les tourelles d'un magasin renfermant des cartouches. Le magasin est situé le plus souvent à proximité du système d'arme et il est généralement formé par une caisse remplie de cartouches reliées entre elles par une bande d'alimentation. It is conventional to equip the turrets with a magazine containing cartridges. The store is located most often near the weapon system and is usually formed by a box filled with cartridges interconnected by a power strip.
Le brevet EP1715281 décrit ainsi un système d'arme comportant deux casiers de cartouches en bande disposés latéralement à l'arme. La bande de cartouches se prolonge du premier casier vers le casier voisin. Une fois un casier vide, il suffit de faire coulisser le casier suivant et de positionner un nouveau casier plein, puis de lier les bandes de cartouches l'une à l'autre. Patent EP1715281 thus describes a weapon system comprising two bunches of tape cartridges arranged laterally to the weapon. The cartridge strip extends from the first bin to the neighboring bin. Once empty, just slide the next rack and position a new full rack, and then tie the strips of cartridges together.
II est cependant nécessaire d'accéder à l'arme pour ces opérations de réapprovisionnement. It is however necessary to access the weapon for these replenishment operations.
Les tourelles sont montées sur un porteur qui peut être un véhicule (terrestre ou naval) ou une structure fixe The turrets are mounted on a carrier that can be a vehicle (land or sea) or a fixed structure
(casemate, bâtiment, immeuble...) . (casemate, building, building ...).
II est impératif aujourd'hui, pour des raisons de sécurité opérationnelle, de permettre aux équipages du porteur (véhicule ou structure fixe) de réapprovisionner l'arme sans sortir du porteur. It is imperative today, for reasons of operational safety, to allow the crews of the carrier (vehicle or fixed structure) to replenish the weapon without leaving the carrier.
Or les tourelles terrestres existantes ne comportent pas de moyens permettant ainsi de réapprovisionner les armes à partir de l'intérieur. However, existing earth turrets do not include means to replenish weapons from within.
On connaît par le brevet WO2011/101853 une tourelle à l'intérieur de laquelle sont disposés plusieurs magasins. Il est possible de faire monter un nouveau magasin dans la
tourelle à l'aide d'un ascenseur. Les bandes de cartouches sont continues d'un magasin à l'autre. Patent WO2011 / 101853 discloses a turret inside which several magazines are arranged. It is possible to bring up a new store in the turret using an elevator. Cartridge tapes are continuous from one store to another.
Ce dispositif permet effectivement un approvisionnement de l'arme à partir de l'intérieur de la tourelle. Il est cependant nécessaire de disposer d'un volume suffisant pour que les différents magasins puissent être logés dans la partie tournante de la tourelle et également pour pouvoir loger l'ascenseur. This device actually allows a supply of the weapon from inside the turret. However, it is necessary to have a sufficient volume so that the different stores can be housed in the rotating part of the turret and also to accommodate the elevator.
Ce dispositif est donc relativement encombrant et complexe. This device is therefore relatively bulky and complex.
On connaît aussi par le brevet US3974738 un magasin intermédiaire permettant de suivre une cadence de tir importante d'une arme. Ce magasin propose de sortir les cartouches de leur bande en amont du magasin puis de les réincorporer dans une autre bande en aval . Also known from US 3974738 an intermediate store to monitor a significant rate of fire of a weapon. This store offers to remove the cartridges from their tape upstream of the store and then reincorporate them in another band downstream.
Ce dispositif est particulièrement complexe et ne permet pas un approvisionnement simple d'un magasin en bandes de cartouches à partir de l'intérieur d'un porteur. This device is particularly complex and does not allow a simple supply of a cartridge strip magazine from inside a carrier.
C'est le but de l'invention que de proposer un dispositif d'alimentation d'une arme en bandes de cartouches ne présentant pas de tels inconvénients. It is the object of the invention to provide a device for feeding a weapon in cartridge strips that does not have such disadvantages.
Ainsi le dispositif selon l'invention est de conception compacte, il n'est pas ou peu intrusif dans le volume interne au porteur réservé à l'équipage et il autorise cependant un réapprovisionnement aisé de l'arme en cartouches à partir de l'intérieur du porteur. Thus the device according to the invention is of compact design, it is not or little intrusive in the internal volume to the carrier reserved for the crew and it allows however easy replenishment of the weapon in cartridges from the inside. of the carrier.
Le dispositif selon l'invention est par ailleurs facilement adaptable à différents types de tourelles d'armes de différents calibres, que ce soit des armes de petit calibre (de 5,56 mm à 14 mm) ou de moyen calibre (de 20mm à 40mm) .

The turret 1 comprises a baseplate la which is fixed to the wall 4 by means of a cylindrical riser 5 with the interposition of a circular bearing 6.
Une couronne 7 solidaire de la plaque d'embase la permet l'entraînement en rotation de la tourelle 1 autour d'un axe 8 vertical de pointage en gisement, à l'aide d'une motorisation solidaire de la paroi 4 et non représentée. A ring 7 integral with the base plate allows it to rotate the turret 1 about a vertical pointing axis 8 in the bearing, with the aid of a motor integral with the wall 4 and not shown.
Le volume interne à la rehausse 5 permet de loger le dispositif d'alimentation en cartouches selon l'invention qui comprend un magasin cylindrique 9 qui est fixé à la plaque d'embase la par des boulons 11 régulièrement répartis angulairement . The internal volume of the riser 5 accommodates the cartridge supply device according to the invention which comprises a cylindrical magazine 9 which is fixed to the base plate 1a by bolts 11 regularly distributed angularly.
Le magasin 9 est destiné à renfermer des cartouches (non visibles sur la figure 1) qui sont liées, de façon classique, les unes aux autres par une bande formée de maillons. The magazine 9 is intended to contain cartridges (not visible in Figure 1) which are conventionally connected to each other by a band formed of links.
Le magasin 9 comporte une goulotte de sortie 10 qui guide la bande de cartouches hors du magasin 9. La goulotte de sortie 10 traverse la plaque d'embase la par un passage approprié. Un couloir souple 12 conduit la bande de cartouches de la goulotte de sortie 10 jusqu'à une ouverture d'alimentation 13 de l'arme 2. The magazine 9 has an outlet chute 10 which guides the cartridge strip out of the magazine 9. The outlet chute 10 passes through the base plate 1a through a suitable passage. A flexible corridor 12 leads the strip of cartridges from the outlet chute 10 to a feed opening 13 of the weapon 2.
Le magasin 9 est disposé coaxialement à l'axe 8 de pointage en gisement de la tourelle 1 et il est lié en rotation à la tourelle 1 lors du pointage en gisement. Le couloir souple 12 permet d'accompagner la bande de cartouches lors des pointages en site de l'arme 2.
Les figures 2, 3, 4a et 4b montrent de façon plus détaillée la structure du dispositif selon l'invention. The magazine 9 is disposed coaxially with the axis 8 pointing bearing of the turret 1 and is rotatably connected to the turret 1 during the bearing pointing. The flexible corridor 12 makes it possible to accompany the band of cartridges during the pointings in site of the weapon 2. Figures 2, 3, 4a and 4b show in more detail the structure of the device according to the invention.
Le magasin 9 comporte une plaque supérieure annulaire 14 solidaire de la plaque d'embase la et qui porte la goulotte de sortie 10 et une plaque inférieure annulaire 15 qui porte une ouverture 16 d'introduction des bandes de cartouches. L'ouverture 16 est obturée par un volet 17 monté sur des charnières 18. Un loquet 19 permet de maintenir le volet fermé comme représenté aux figures 2 et 3. The magazine 9 has an annular upper plate 14 integral with the base plate 1a and which carries the outlet chute 10 and an annular lower plate 15 which carries an opening 16 for introducing the strips of cartridges. The opening 16 is closed by a flap 17 mounted on hinges 18. A latch 19 keeps the shutter closed as shown in Figures 2 and 3.
La plaque inférieure 15 comporte un rebord cylindrique externe 15a qui lui est soudé et qui ferme l'intérieur du magasin 9. Ce rebord 15a est retiré sur les figures 2, 4a et 4b pour montrer l'intérieur du magasin. The lower plate 15 has an outer cylindrical rim 15a welded to it and closes the interior of the magazine 9. This rim 15a is removed in Figures 2, 4a and 4b to show the interior of the magazine.
Les plaques inférieure 15 et supérieure 14 sont ici réalisées en tôle d'acier. The lower and upper plates 14 are here made of sheet steel.
L'ouverture 16 aménagée dans la plaque inférieure 15 est destinée à communiquer avec l'intérieur de l'habitacle 21 du porteur. Pour cela, un passage 20 (figure 1) est aménagé dans la paroi 4, passage qui permet de manœuvrer le volet 17. The opening 16 arranged in the lower plate 15 is intended to communicate with the interior of the passenger compartment 21 of the carrier. For this purpose, a passage 20 (FIG. 1) is arranged in the wall 4, which passage makes it possible to maneuver the shutter 17.
Le magasin 9 comporte aussi un cylindre interne 22 coaxial à l'axe de pointage en gisement 8. Ce cylindre 22 est positionné au niveau des ouvertures des deux plaques 14 et 15. Le diamètre externe du cylindre 22 est supérieur au diamètre des ouvertures des plaques. Ainsi les plaques 14 et 15 sont maintenues à une distance l'une de l'autre qui est égale à la longueur du cylindre 22. Ce cylindre 22 constitue une liaison pivot lisse entre la plaque supérieure 14 et la plaque inférieure 15. On entend par pivot lisse un pivot d'une pièce cylindrique dans une autre pièce cylindrique et qui est possible grâce à la présence d'un jeu fonctionnel entre les pièces (avec ou sans coussinet) et sans interposition d'un élément roulant (tel un roulement à bille) .
Comme on le voit plus clairement sur la figure 3, le cylindre interne 22 porte une bague de guidage inférieure 23 et une bague de guidage supérieure 24. Chaque bague 23 ou 24 est fixée au cylindre 22 par des vis radiales 25. Les bagues inférieure 23 et supérieure 24 comportent chacune une portée 23a ou 24a qui forme une butée venant en appui contre une des plaques 14 ou 15. Ainsi les plaques 14 et 15 sont emprisonnées entre les butées 23a et 24a des bagues 23 et 24. On laissera un jeu de quelques dixièmes de millimètre entre butées 23a, 23b et plaques 14,15. Ainsi le cylindre 22 sera libre en rotation par rapport aux plaques inférieure 15 et supérieure 14. La plaque inférieure 15 pourra par ailleurs elle-même pivoter par rapport au cylindre 22. Les bagues butées de guidage 23 et 24 seront réalisées en acier tout comme le cylindre 22 et les plaques 14 et 15. The magazine 9 also has an internal cylinder 22 coaxial with the pointing axis 8. This cylinder 22 is positioned at the openings of the two plates 14 and 15. The outer diameter of the cylinder 22 is greater than the diameter of the openings of the plates. . Thus the plates 14 and 15 are held at a distance from each other which is equal to the length of the cylinder 22. This cylinder 22 constitutes a smooth pivot connection between the upper plate 14 and the lower plate 15. By pivot smooth a pivot of a cylindrical part in another cylindrical part and which is possible due to the presence of a functional clearance between the parts (with or without pad) and without the interposition of a rolling element (such as a ball bearing ). As can be seen more clearly in FIG. 3, the inner cylinder 22 carries a lower guide ring 23 and an upper guide ring 24. Each ring 23 or 24 is fixed to the cylinder 22 by radial screws 25. The lower rings 23 and upper 24 each comprise a bearing surface 23a or 24a which forms a stop abutting against one of the plates 14 or 15. Thus the plates 14 and 15 are trapped between the stops 23a and 24a of the rings 23 and 24. It will be left a set of a few tenths of a millimeter between abutments 23a, 23b and plates 14,15. Thus, the cylinder 22 will be free to rotate with respect to the lower and upper plates 14. The lower plate 15 may itself pivot itself relative to the cylinder 22. The guide stops 23 and 24 will be made of steel just like the cylinder 22 and the plates 14 and 15.
A titre de variante il serait possible de remplacer le cylindre 22 par un simple fût cylindrique, solidaire d'une des plaques (inférieure ou supérieure) , et par rapport auquel l'autre plaque pourra pivoter en pivot lisse grâce à un jeu fonctionnel approprié. Alternatively, it would be possible to replace the cylinder 22 with a simple cylindrical barrel, secured to one of the plates (lower or upper), and relative to which the other plate can pivot in a smooth pivot through a suitable functional game.
Comme on le voit sur la figure 3, le dispositif comporte un renfort annulaire 26 qui est solidaire de la plaque inférieure 15 par des vis 27. Ce renfort 26 est réalisé en alliage d'aluminium. Il comporte une surface convexe qui est destinée à recevoir le profil externe des projectiles 28 des cartouches 29. Le renfort 26 assure un calage des cartouches en limitant le basculement du projectile 28 vers la plaque inférieure 15. As seen in Figure 3, the device comprises an annular reinforcement 26 which is secured to the lower plate 15 by screws 27. This reinforcement 26 is made of aluminum alloy. It comprises a convex surface which is intended to receive the external profile of the projectiles 28 of the cartridges 29. The reinforcement 26 provides a cushioning of the cartridges by limiting the tilting of the projectile 28 towards the lower plate 15.
Comme on le voit clairement sur les figures 2, 3 et 8, les cartouches 29 mises en place dans le magasin 9 sont logées dans le magasin avec toutes leur axe orienté radialement par rapport à l'axe 8 de pointage en gisement. Le culot des cartouches est dirigé vers le rebord cylindrique
externe 15a du magasin 9 et les projectiles ont leur ogive qui est pointée vers le cylindre 22. As can be seen clearly in FIGS. 2, 3 and 8, the cartridges 29 placed in the magazine 9 are housed in the magazine with all their axis oriented radially with respect to the bearing pointing axis 8. The base of the cartridges is directed towards the cylindrical rim external 15a of the magazine 9 and the projectiles have their warhead which is pointed towards the cylinder 22.
La figure 8 montre le magasin en vue de dessus et en coupe. Toutes les cartouches 29 sont disposées avec leur bande enroulée autour de l'axe 8 de pointage en gisement. Avec les dimensions du mode de réalisation représenté (ici des cartouches de calibre 20mm) , le magasin 9 peut recevoir trois couches de cartouches, ce qui représente une centaine de cartouches. Figure 8 shows the store in plan view and in section. All the cartridges 29 are arranged with their band wound around the axis 8 pointing pointing. With the dimensions of the embodiment shown (here cartridges of 20mm caliber), the magazine 9 can receive three layers of cartridges, which represents a hundred cartridges.
Comme on le voit à la figure 2, la goulotte de sortie 10 a un profil courbe 10a permettant de diriger la bande de cartouches vers l'ouverture d'alimentation 13 de l'arme 2. La goulotte de sortie est réalisée en tôle pliée et soudée. Elle comporte des pattes permettant son accrochage au niveau d'une ouverture supérieure 30 de la plaque supérieure 14. La goulotte 10 est par ailleurs solidaire d'une cornière 33 qui permet sa fixation à la plaque d'embase la. As seen in Figure 2, the outlet chute 10 has a curved profile 10a for directing the strip of cartridges to the feed opening 13 of the weapon 2. The outlet chute is made of folded sheet and welded. It comprises tabs allowing it to hang at an upper opening 30 of the upper plate 14. The chute 10 is also secured to an angle bracket 33 which allows it to be attached to the baseplate 1a.
La goulotte de sortie 10 comporte un bec 10b courbe qui est positionné à l'intérieur du magasin 9 et qui forme une butée permettant d'empêcher un retour des cartouches dans le sens inverse de l'enroulement de chargement initial. The outlet chute 10 has a curved beak 10b which is positioned inside the magazine 9 and which forms a stop to prevent a return of the cartridges in the opposite direction of the initial loading winding.
Il y a une seule et même bande qui est enroulée de façon à former trois couches de cartouches. On a schématisé sur la figure 2 par des traits forts les liens entre deux cartouches successives de la bande. La cartouche repérée 29a est la cartouche la plus proche de la goulotte de sortie 10 et la cartouche repérée 29b est la dernière cartouche de la bande qui est présente dans le magasin 9. There is one and the same band that is rolled up to form three layers of cartridges. FIG. 2 shows schematically the strong links between two successive cartridges of the strip. The marked cartridge 29a is the cartridge closest to the outlet chute 10 and the marked cartridge 29b is the last cartridge of the strip which is present in the magazine 9.
Les figures 5, 6 et 7 montrent le magasin 9 lors d'une phase de réapprovisionnement en cartouches. Figures 5, 6 and 7 show the magazine 9 during a replenishment phase cartridges.
Pour cela on ouvre le volet 17 et on positionne dans l'ouverture inférieure 16 une goulotte d'entrée 31 amovible. Cette pièce est une sorte d'entonnoir en tôle pliée qui est délimité par des parois convergentes. La goulotte d'entrée 31
renferme un cylindre 32 qui est ici libre en rotation par rapport à la goulotte et qui assure un guidage de la bande de cartouches en réduisant les frottements et l'accrochage de celle-ci sur les tôles des parois du dispositif. For this we open the flap 17 and is positioned in the lower opening 16 a removable inlet chute 31. This piece is a kind of folded sheet funnel which is delimited by converging walls. The inlet chute 31 encloses a cylinder 32 which is free to rotate with respect to the chute and which guides the strip of cartridges by reducing the friction and the attachment thereof to the wall plates of the device.
Le magasin selon l'invention est approvisionné de la façon suivante . The store according to the invention is supplied as follows.
Lorsque le magasin est vide, on fixe une bande de cartouches sur l'arme 2 au niveau de l'ouverture d'alimentation 13 puis on introduit la bande dans le magasin 9 au travers de la goulotte de sortie 10 et on fait sortir la bande à l'intérieur de l'habitacle 21 au travers de l'ouverture d'introduction 16 équipée de la goulotte d'entrée 31. When the magazine is empty, a strip of cartridges is attached to the weapon 2 at the feed opening 13, then the strip is introduced into the magazine 9 through the outlet chute 10 and the strip is taken out. inside the passenger compartment 21 through the introduction opening 16 equipped with the inlet chute 31.
On fait ensuite tourner la tourelle par sa propre motorisation de pointage en gisement. Cette rotation est commandée à l'aide d'une télécommande (non représentée) . The turret is then rotated by its own pointing engine in the field. This rotation is controlled using a remote control (not shown).
La plaque supérieure 14 étant solidaire de la tourelle 1, cette rotation entraîne la bande de cartouches qui se love à l'intérieur du magasin 9. La plaque inférieure 15, maintenue par l'opérateur ou par une cale, ne bouge pas car elle est libre en rotation grâce au jeu existant entre le cylindre 22 et la plaque supérieure 14. The upper plate 14 being secured to the turret 1, this rotation causes the strip of cartridges that coils inside the magazine 9. The lower plate 15, maintained by the operator or a wedge, does not move because it is free rotation thanks to the existing clearance between the cylinder 22 and the upper plate 14.
On fait ainsi tourner la tourelle 1 autour de son axe de gisement du nombre de tours correspondant au nombre de couches de cartouches que peut recevoir le magasin 9. The turret 1 is thus rotated around its bearing axis by the number of revolutions corresponding to the number of layers of cartridges that the magazine 9 can receive.
Chaque tour de la tourelle de 360° positionne une rangée de cartouches. Pour le mode de réalisation qui est décrit ici, au bout de trois tours de la tourelle 1 le magasin 9 est complètement rempli. Each turn of the 360 ° turret positions a row of cartridges. For the embodiment described here, after three turns of the turret 1 the magazine 9 is completely filled.
II est clair que la mise en place d'une rehausse 5 plus haute permettrait de loger davantage de couches de cartouches . It is clear that the establishment of a higher raising 5 would allow to house more layers of cartridges.
On prévoira de préférence lors de l'approvisionnement un nombre de cartouches égal à celui pouvant être contenu dans
le magasin. Si le nombre de cartouches est supérieur, après remplissage, on détachera éventuellement les dernières cartouches 29 de la bande. When supplying, a number of cartridges should preferably be equal to that which may be contained in the shop. If the number of cartridges is higher, after filling, it will eventually detach the last cartridges 29 of the band.
On retire enfin la goulotte d'entrée 31 et on ferme le volet 17. Finally, the inlet chute 31 is removed and the flap 17 is closed.
Lors d'un tir, l'arme exerce de façon classique une traction sur la bande de cartouches. Le cylindre 22 et la plaque inférieure 15 étant libres en rotation par rapport à la plaque supérieure, la traction de la bande fait sortir cette dernière du magasin avec un effort réduit. During a shot, the weapon typically exercises a pull on the tape cartridges. The cylinder 22 and the lower plate 15 being free in rotation with respect to the upper plate, the traction of the strip makes it leave the magazine with a reduced effort.
On notera que les accélérations angulaires de la tourelle 1 ne provoquent cependant pas de perturbations au niveau du garnissage du magasin 9. Les efforts de frottements à l'intérieur du magasin (dus au pivot lisse) sont en effet suffisants pour limiter les pivotements libres de la plaque 15 par rapport à l'autre plaque 14 en l'absence d'efforts de traction exercés sur la bande de cartouches. Pour cela le jeu fonctionnel du pivot lisse réalisé entre le cylindre 22 et les plaques 14 et 15 est de l'ordre de quelques dixièmes de millimètres. Note that the angular accelerations of the turret 1, however, do not cause disturbances in the lining of the magazine 9. The friction forces inside the magazine (due to the smooth pivot) are indeed sufficient to limit the free pivoting of the plate 15 relative to the other plate 14 in the absence of tensile forces exerted on the strip of cartridges. For this, the functional clearance of the smooth pivot made between the cylinder 22 and the plates 14 and 15 is of the order of a few tenths of a millimeter.
Par ailleurs la butée 10b empêche un retour des cartouches dans un sens inverse à celui de l'enroulement de chargement . Furthermore the stop 10b prevents a return of the cartridges in a direction opposite to that of the loading winding.
Lorsque les servants de l'arme souhaitent réappro- visionner le magasin 9, il n'est pas nécessaire de sortir de l'habitacle du porteur. When the servants of the weapon wish to reapply the magazine 9, it is not necessary to leave the passenger compartment.
Ce réapprovisionnement doit bien sûr être réalisé avant le vidage complet du magasin 9. This replenishment must of course be made before the complete emptying of the magazine 9.
Pour opérer un tel réapprovisionnement la procédure est la suivante : To operate such a replenishment, the procedure is as follows:
Tourelle à l'arrêt, on ouvre le volet 17 de l'ouverture d'introduction 16. On positionne ensuite la goulotte d'entrée amovible 31 au niveau de cette ouverture 16.
On fait ensuite pivoter la tourelle 1 d'une fraction de tour (par exemple par une avance pas à pas) jusqu'à la sortie par l'ouverture de la dernière cartouche 29b de la bande qui est en place dans le magasin 9. La sortie de la dernière cartouche peut être facilitée par un outil à main, tel un crochet . When the turret is stopped, the flap 17 of the introduction opening 16 is opened. The removable entrance chute 31 is then positioned at this opening 16. The turret 1 is then rotated a fraction of a turn (for example by a step advance) to the exit by the opening of the last cartridge 29b of the band which is in place in the magazine 9. The output of the last cartridge can be facilitated by a hand tool, such as a hook.
On notera que la liberté de rotation de la plaque inférieure 15 a permis de positionner l'ouverture 16 en regard du passage 20 aménagé dans la paroi 4 de l'habitacle 21. Note that the freedom of rotation of the lower plate 15 has positioned the opening 16 facing the passage 20 arranged in the wall 4 of the passenger compartment 21.
On fixe à la bande de cartouches, qui sort du magasin 9 par l'ouverture 16, une bande de réapprovisionnement en cartouches sortie d'une réserve présente dans l'habitacle. Cette fixation entre les maillons de deux bandes est classique et n'a pas à être décrite en détails. The cartridge strip, which leaves the magazine 9 through the opening 16, is fixed to a strip of replenishment cartridges out of a reserve in the passenger compartment. This attachment between the links of two bands is conventional and does not have to be described in detail.
Comme pour l'approvisionnement initial, on fait ensuite pivoter la tourelle du nombre de tours permettant de remplir le magasin 9. As for the initial supply, the turret is then rotated by the number of turns to fill the magazine 9.
Comme pour le remplissage initial, on prévoira de préférence pour le réapprovisionnement un nombre de cartouches égal à celui pouvant être contenu dans le magasin. As for the initial filling, a number of cartridges equal to that which may be contained in the magazine will preferably be provided for refilling.
Si le nombre de cartouches est supérieur, après remplissage, on détachera éventuellement les cartouches ne pouvant pas entrer dans le magasin 9. If the number of cartridges is higher, after filling, it will be possible to detach the cartridges that can not enter the magazine 9.
On retire enfin la goulotte d'entrée 31 et on referme le volet 17. Finally, the inlet chute 31 is removed and the flap 17 is closed.
On voit que le dispositif d'alimentation selon l'invention permet de réaliser un réapprovisionnement sous protection à partir de l'intérieur de l'habitacle du porteur (véhicule ou structure fixe) . It can be seen that the feed device according to the invention makes it possible to replenish under protection from inside the passenger compartment (vehicle or fixed structure).
Le dispositif selon l'invention est de structure très simple et s'intègre facilement sous une tourelle en prévoyant une rehausse adaptée.
Ce dispositif peut être facilement décliné pour tout calibre de cartouches, qu'elles soient de petit calibre ou de moyen calibre.
The device according to the invention is of very simple structure and easily integrates under a turret by providing a suitable extension. This device can be easily declined for any caliber of cartridges, whether small or medium caliber.
