Description

Le domaine technique de l'invention est celui des systèmes d'arme légers adaptables à une trappe de véhicule.The technical field of the invention is that of light weapon systems adaptable to a vehicle hatch.

Les véhicules blindés à usage militaire comportent souvent un panel d'armes adaptées à leur mission principale. Dans le cas d'un char qui est un véhicule spécialisé dans le tir direct ou tir tendu, celui-ci comporte un canon pour le tir direct antichar ou anti infrastructures. Cette arme est souvent associée avec une arme secondaire de petit ou de moyen calibre destinée au tir direct antipersonnel ou anti matériels légers.Armored vehicles for military use often include a panel of weapons adapted to their main mission. In the case of a tank that is a vehicle specialized in direct fire or tight fire, it includes a gun for direct anti-tank fire or anti infrastructure. This weapon is often associated with a secondary weapon of small or medium caliber intended for the direct fire antipersonnel or anti light material.

Certaines missions demandent pourtant plus de polyvalence et une arme destinée au tir indirect ou tir balistique courbe est souhaitée. Pour cela il est connu d'équiper les personnels avec des mortiers légers (calibre 40 à 80 mm) ou des lance grenades portatifs. Ceux-ci doivent être servis depuis l'extérieur du véhicule ce qui implique une exposition des servants à des tirs ennemis ceci n'étant pas admissible.Some missions however require more versatility and a weapon for indirect fire or ballistic ballistic fire is desired. For this it is known to equip personnel with light mortars (caliber 40 to 80 mm) or grenade launcher portable. These must be served from outside the vehicle which implies an exposure of the crew to enemy fire this is not admissible.

D'autre part il est connu du brevet FR2572803 un mortier pour véhicule qui est servi sous tourelle pour assurer la protection des servants. Un tel dispositif engendre un impact lourd sur le véhicule dont l'architecture doit être profondément modifiée pour intégrer le mortier dans l'habitacle du véhicule. Ce type d'impact n'est pas admissible pour un armement qui se veut optionnel.On the other hand it is known from the patent FR2572803 a mortar for a vehicle that is under turret to protect the crew. Such a device generates a heavy impact on the vehicle whose architecture must be deeply modified to integrate the mortar in the passenger compartment of the vehicle. This type of impact is not admissible for an armament that wants to be optional.

On connaît aussi par le brevet EP0011856 une tourelle de véhicule blindé comportant un support d'arme rigidement solidaire de la tourelle. Cependant ce support d'arme n'est pas un système d'arme léger pouvant s'interfacer avec un trou d'homme.Also known by the patent EP0011856 an armored vehicle turret comprising a weapon support rigidly secured to the turret. However, this weapon support is not a light weapon system that can interface with a manhole.

On connaît par le brevet FR2674949 un mortier à chargement par l'arrière. Ce système d'arme est l'armement principal de la tourelle et non un armement secondaire. Il nécessite des moyens spécifiques (non décrits par ce brevet) permettant un chargement du mortier au travers de la tourelle et permettant aussi de commander le pivotement d'une chemise porte projectile de ce mortier à partir de l'intérieur de la tourelle. Ce système est donc lourd et complexe. On connaît par EP1318375 un système d'arme léger destiné à s'interfacer sur un trou d'homme d'un habitacle, ledit système comportant une rehausse entourant le trou d'homme et s'étendant verticalement au-dessus du trou d'homme, rehausse obturée par une trappe articulée. On connaît enfin par le brevet EP1273869 un véhicule comportant deux mortiers à chargement par la bouche qui sont servis sous blindage. Là c'est tout le véhicule qui est dévolu à l'alimentation de chaque mortier en munitions. Ce dispositif est donc lui aussi complexe, et il ne peut pas être associé à une tourelle sans un impact important sur l'architecture du véhicule.We know by the patent FR2674949 a mortar with rear loading. This weapon system is the main armament of the turret and not a secondary armament. he requires specific means (not described by this patent) for loading the mortar through the turret and also to control the pivoting of a projectile bearing liner of this mortar from inside the turret. This system is therefore heavy and complex. We know by EP1318375 a light weapon system for interfacing with a manhole of a passenger compartment, said system comprising a riser surrounding the manhole and extending vertically above the manhole, raises closed by an articulated hatch. Finally, we know by the patent EP1273869 a vehicle with two mortars loaded by the muzzle that are served under armor. There it is the whole vehicle that is devoted to feeding each mortar ammunition. This device is therefore also complex, and it can not be associated with a turret without a significant impact on the architecture of the vehicle.

L'invention propose un système d'arme pouvant équiper un véhicule, système d'arme de type mortier qui peut être servi depuis l'intérieur du véhicule et sans engendrer d'impact lourd sur l'architecture du véhicule.The invention proposes a weapon system that can equip a vehicle, mortar-type weapon system that can be served from inside the vehicle and without causing a heavy impact on the architecture of the vehicle.

Ainsi l'invention a pour objet un système d'arme léger destiné à tirer des obus de mortier et à s'interfacer sur un trou d'homme d'un habitacle, système d'arme comportant :

  • un tube de mortier,
  • une rehausse entourant le trou d'homme et s'étendant verticalement au-dessus du trou d'homme, rehausse obturée par une trappe articulée et comportant une ouverture destinée à permettre d'alimenter le tube de mortier par sa bouche avec un obus,
  • un support du tube de mortier solidaire fixement de la rehausse par une première extrémité et comportant à sa seconde extrémité une liaison pivot solidaire du tube de mortier,
  • l'ouverture débouchant, vers l'extérieur de la rehausse, entre des flancs du support et en regard de la bouche du tube lorsque celui-ci est à l'horizontale,
  • un moyen d'orientation en site du tube de mortier,
  • un moyen de mise à feu destiné à déclencher le tir de l'obus.
Thus the invention relates to a light weapon system for firing mortar shells and interfacing on a manhole of a cockpit, weapon system comprising:
  • a mortar tube,
  • a raiser surrounding the manhole and extending vertically above the manhole, raises closed by a hinged door and having an opening for feeding the mortar tube through its mouth with a shell,
  • a support of the mortar tube secured to the socket by a first end and having at its second end a pivot connection secured to the mortar tube,
  • the opening opening, towards the outside of the extension, between flanks of the support and facing the mouth of the tube when it is horizontal,
  • means for orienting the mortar tube at the site,
  • firing means for firing the shell.

Selon un mode de réalisation l'invention le système d'arme léger comporte un moyen de fermeture de l'ouverture garantissant une protection balistique.According to one embodiment of the invention the light weapon system comprises a closure means of the opening ensuring a ballistic protection.

Avantageusement le moyen de fermeture est solidaire d'un moyen de chargement comportant un tiroir destiné à contenir un obus, le tiroir étant monté coulissant par une liaison glissière dans l'ouverture de la rehausse.Advantageously, the closure means is secured to a loading means comprising a drawer intended to contain a shell, the slide being slidably mounted by a sliding connection in the opening of the riser.

Avantageusement le tiroir comporte une goulotte destinée à laisser passer le tube, le tiroir poussant lors de son coulissement l'obus dans la bouche du tube.Advantageously, the drawer has a chute for passing the tube, the drawer pushing when sliding the shell in the mouth of the tube.

Avantageusement la goulotte du tiroir est ouverte dans sa partie supérieure pour laisser entrer et sortir du tiroir la bouche du tube durant les mouvements de positionnement en site de celui-ci.Advantageously, the chute of the drawer is open in its upper part to let in and out of the drawer the mouth of the tube during positioning movements in site thereof.

Le système d'arme léger pourra comporter un capteur d'angle de site destiné à donner le pointage en hausse du tube.The light weapon system may include a site angle sensor for pointing up the tube.

Avantageusement le moyen de mise de feu est un percuteur commandable depuis l'intérieur du véhicule et situé dans la culasse du tube.Advantageously, the firing means is a striker controllable from inside the vehicle and located in the cylinder head of the tube.

Avantageusement, le moyen d'orientation en site du tube est un vérin électrique.Advantageously, the tube orientation means of the tube is an electric jack.

The invention will be better understood on reading the following description given with reference to the accompanying drawings in which:
  • The figure 1 represents a three-quarter view of a light weapon system according to the invention mounted on a vehicle.
  • The figure 2 represents an upper three-quarter view of a light weapon system according to the invention.

Selon la figure 1, une tourelle 100 d'un véhicule blindé (véhicule représenté très schématiquement) comporte deux trous d'homme 101 et 102 destinés à laisser entrer ou sortir tout ou partie d'un membre d'équipage dans un habitacle formé par la tourelle 100.According to figure 1 , a turret 100 of an armored vehicle (vehicle shown very schematically) comprises two manholes 101 and 102 intended to let in or out all or part of a crew member in a passenger compartment formed by the turret 100.

Chaque trou d'homme est obturé par une trappe articulée 101a et 102a. Un des trous d'homme 101 porte un système d'arme léger 1 selon l'invention, qui est destiné à tirer des obus de mortier.Each manhole is closed by an articulated hatch 101a and 102a. One of the manholes 101 carries a light weapon system 1 according to the invention, which is intended to fire mortar shells.

Ce système d'arme 1 comporte un tube de mortier 2 qui est, selon le mode de réalisation représenté, orienté en gisement parallèlement à l'arme principale 100a de la tourelle 100. Le pointage en gisement du système d'arme 1 sera donc effectué par la rotation de la tourelle ou du véhicule entier. Le système d'arme 1 est fixé au niveau du trou d'homme par des moyens de fixation classiques, tels que des vis et/ou boulons, d'autres moyens pourront être employés.This weapon system 1 comprises a mortar tube 2 which is, according to the embodiment shown, oriented in parallel with the reference to the main weapon 100a of the turret 100. The bearing pointing of the weapon system 1 will therefore be carried out by rotating the turret or the entire vehicle. The weapon system 1 is fixed at the manhole by conventional fastening means, such as screws and / or bolts, other means may be used.

Il est envisageable de solidariser le système d'arme 1 avec le véhicule dans une autre position relativement à l'axe longitudinal du véhicule ou de la tourelle. Ainsi, on pourra solidariser le système d'arme perpendiculairement à l'arme principale 100a de la tourelle par exemple.It is conceivable to secure the weapon system 1 with the vehicle in another position relative to the longitudinal axis of the vehicle or the turret. Thus, it will be possible to secure the weapon system perpendicularly to the main weapon 100a of the turret, for example.

Selon la figure 2, le système d'arme comporte une rehausse 3 qui s'étend verticalement au-dessus du trou d'homme 101a (trou non visible). Cette rehausse 3 entoure toute la périphérie du trou d'homme. Un support 4 du tube de mortier 2 est solidaire de façon fixe au niveau d'une première extrémité de la rehausse 2, en-dessous d'une charnière 5 servant à l'ouverture de la trappe 6. Le support 4 s'étendant sensiblement horizontalement dans un plan d'interfaçage P du système d'arme 1 sur le trou d'homme. Le support 4 comporte à sa seconde extrémité une liaison pivot 4b destinée à permettre la rotation du tube 2 autour de l'axe horizontal A pour orienter le tube 2 en site et régler ainsi la hausse.According to figure 2 , the weapon system comprises a riser 3 which extends vertically above the manhole 101a (not visible hole). This enhancement 3 surrounds the entire periphery of the manhole. A support 4 of the mortar tube 2 is secured in a fixed manner at a first end of the riser 2, below a hinge 5 serving to open the hatch 6. The support 4 extending substantially horizontally in an interfacing plane P of the weapon system 1 on the manhole. The support 4 comprises at its second end a pivot connection 4b intended to allow the rotation of the tube 2 around the horizontal axis A to orient the tube 2 in place and thus adjust the rise.

Selon le mode de réalisation représenté, le support 4 comporte deux flancs latéraux 4a entre lesquels une partie avant du tube 2 comportant la bouche du tube 2a peut se placer lorsqu'il est à l'horizontal.According to the embodiment shown, the support 4 comprises two lateral flanks 4a between which a front portion of the tube 2 having the mouth of the tube 2a can be placed when it is horizontal.

Le système d'arme 1 comporte un moyen d'orientation 7 du tube 2 en site. Selon le mode de réalisation représenté, le moyen d'orientation 7 est un vérin électrique solidaire d'un flanc 4a du support 4 et solidaire par une autre extrémité de la liaison pivot 4b liée au tube 2 (par exemple par un système bielle - manivelle).The weapon system 1 comprises an orientation means 7 of the tube 2 in site. According to the embodiment shown, the orientation means 7 is an electric jack secured to a flank 4a of the support 4 and secured by another end of the pivot connection 4b connected to the tube 2 (for example by a connecting rod - crank system ).

Selon un autre mode de réalisation illustré à la figure 7, la seconde extrémité du vérin pourra être solidaire du tube 2 directement. Ce vérin 7 est commandable depuis l'habitacle de la tourelle 100.According to another embodiment illustrated in figure 7 , the second end of the jack may be integral with the tube 2 directly. This cylinder 7 is controllable from the cabin of the turret 100.

Le système d'arme 1 comporte un moyen de mesure (non représenté) de l'orientation en site du tube 2. De tels moyens sont bien connus de l'Homme du Métier, ils peuvent être constitués par un capteur angulaire par exemple ou tout autre moyen de mesure permettant d'indiquer la valeur de pointage en site du tube à un servant du système d'arme situé dans l'habitacle de la tourelle 100.The weapon system 1 comprises a measuring means (not shown) for the orientation of the tube 2. Such means are well known to those skilled in the art, they may be constituted by an angular sensor for example or any other measuring means for indicating the value of pointing in site of the tube to a servant of the weapon system located in the cabin of the turret 100.

Selon la figure 3, le système d'arme 1 est représenté sans sa trappe ni sa charnière afin de voir le fonctionnement interne du système d'arme 1.According to figure 3 , the weapon system 1 is shown without its hatch or hinge to see the internal operation of the weapon system 1.

Ainsi, on voit que la rehausse 3 comporte dans sa paroi une ouverture 8 débouchant, vers l'extérieur de la rehausse 3, entre les flancs 4a du support 4 et en regard de la bouche 2a du tube 2 lorsque celui-ci est à l'horizontale.Thus, we see that the riser 3 has in its wall an opening 8 opening, towards the outside of the extension 3, between the flanks 4a of the support 4 and facing the mouth 2a of the tube 2 when it is at the horizontal.

Cette ouverture 8 correspond avec un moyen de chargement 9 du tube 2. Ce moyen de chargement pourra être un tiroir 9 qui est monté coulissant par une liaison glissière 10 dans l'ouverture 8, le tiroir coulissant de l'intérieur de la rehausse 3 vers l'extérieur et inversement.This opening 8 corresponds with a loading means 9 of the tube 2. This loading means may be a slide 9 which is slidably mounted by a sliding connection 10 in the opening 8, the sliding drawer of the inside of the riser 3 to outside and vice versa.

A la figure 8 notamment, on voit que le tiroir 9 comporte sur un de ses cotés une fenêtre 11 destinée à permettre de placer un obus 12 à l'intérieur du tiroir 9. On notera que l'obus 12 est placé de manière à ce que sa partie arrière soit la plus proche de l'ouverture 8 afin que cette partie rentre par la suite la première dans la bouche 2a du tube 2 lors du chargement de l'obus 12 tel que représenté à la figure 4.To the figure 8 in particular, we see that the drawer 9 has on one of its sides a window 11 intended to allow to place a shell 12 inside the drawer 9. Note that the shell 12 is placed so that its rear part is closest to the opening 8 so that this part subsequently enters the first in the mouth 2a of the tube 2 during the loading of the shell 12 as shown in FIG. figure 4 .

Lors du chargement, depuis l'habitacle de la tourelle 100, le servant a accès au tiroir tout en étant protégé par la trappe 6 qui obture la rehausse (trappe non représentée à la figure 4). Il pousse le tiroir en direction du tube 2a, faisant ainsi pénétrer l'obus 12 dans la bouche du tube 2a.During loading, from the cabin of the turret 100, the servant has access to the drawer while being protected by the hatch 6 which closes the raiser (hatch not shown at the figure 4 ). It pushes the drawer towards the tube 2a, thus causing the shell 12 to enter the mouth of the tube 2a.

Comme on le voit sur la figure 8, le tiroir 9 a une forme de civière et comporte donc une goulotte 9a qui est dimensionnée de façon à laisser entrer le tube 2 dans le tiroir 9 lorsqu'on pousse ce dernier pour faire coulisser l'obus 12 dans la bouche 2a du tube 2.As we see on the figure 8 , the drawer 9 has a stretcher shape and therefore comprises a chute 9a which is dimensioned so as to allow the tube 2 to enter the drawer 9 when the latter is pushed to slide the shell 12 into the mouth 2a of the tube 2 .

La goulotte 9a du tiroir 9 est par ailleurs complètement ouverte dans sa partie supérieure. Ainsi le tube peut être pivoté pour son positionnement en site sans être gêné par le tiroir 9.The chute 9a of the drawer 9 is also completely open in its upper part. Thus the tube can be rotated for its positioning in the site without being obstructed by the drawer 9.

Selon la figure 5, une fois le tiroir 9 poussé au fond de l'ouverture 8, entre les flancs 4a du support 4, l'obus est complètement enfoncé dans la partie avant 2a du tube 2. Le tiroir 9 porte à sa partie arrière une plaque 9b (figure 8) formant un moyen de fermeture du fond de l'ouverture 8. Cette plaque 9b assure la protection balistique de la rehausse 3 une fois le tube basculé. Un moyen de verrouillage (non représenté) permettra de verrouiller le tiroir 9 par rapport à la rehausse 3 dans cette position. La plaque 9b sera réalisée dans un matériau ayant des capacités de résistance analogues à celle de la rehausse 3 et aura une épaisseur du même ordre que celle de la rehausse.According to figure 5 once the slide 9 is pushed to the bottom of the opening 8, between the flanks 4a of the support 4, the shell is completely pushed into the front portion 2a of the tube 2. The slide 9 carries at its rear part a plate 9b ( figure 8 ) forming a closing means of the bottom of the opening 8. This plate 9b provides ballistic protection of the riser 3 after the tube tilted. A locking means (not shown) will lock the drawer 9 relative to the riser 3 in this position. The plate 9b will be made of a material having resistance capabilities similar to that of the riser 3 and will have a thickness of the same order as that of the riser.

Le tiroir 9 est donc ouvert sur sa partie supérieure laissant le tube 2 apparent et libre de se mouvoir vers le haut.The drawer 9 is open on its upper part leaving the tube 2 apparent and free to move upwards.

Selon la figure 6 le servant commande la mise au site de tir souhaité depuis l'intérieur de la tourelle en activant le vérin 7. Le tube 2, sous l'action du moyen d'orientation 7, opère un relèvement de la bouche 2a du tube qui provoque la descente de l'obus au fond du tube 2 par gravité.According to figure 6 the servant controls the setting firing site from the inside of the turret by activating the cylinder 7. The tube 2, under the action of the orientation means 7, raises the mouth 2a of the tube which causes the descent of the shell at the bottom of the tube 2 by gravity.

Une fois la position de site de tir souhaitée obtenue, le servant peut commander la mise à feu de l'obus par un moyen classiquement connu de l'homme du métier tel qu'un percuteur commandable à distance situé dans la culasse 2b du tube 2.Once the desired firing site position has been obtained, the servant can control the firing of the shell by means conventionally known to those skilled in the art such as a remotely controllable striker located in the cylinder head 2b of the tube 2.

Suivant un mode de réalisation plus simple du système d'arme selon l'invention, il est envisageable de ne pas équiper le système d'arme d'un tiroir de chargement. L'obus sera dans ce cas introduit manuellement dans la bouche du tube au travers de l'ouverture 8.According to a simpler embodiment of the weapon system according to the invention, it is conceivable not to equip the weapon system with a loading drawer. In this case, the shell will be inserted manually into the mouth of the tube through the opening 8.

Un volet pivotant peut être prévu pour fermer l'ouverture 8 mais l'étanchéité balistique n'est dans ce cas pas garantie pendant la phase de chargement. Cependant la faible dimension de l'ouverture 8 et sa situation protégée par les flancs 4a du support 4 offre une faible exposition du servant vis-à-vis des menaces balistiques.A pivoting flap may be provided to close the opening 8 but the ballistic seal is not guaranteed in this case during the loading phase. However, the small size of the opening 8 and its position protected by the flanks 4a of the support 4 provides a low exposure of the servant vis-à-vis the ballistic threats.

Ainsi, l'invention permet d'équiper un véhicule blindé d'un système d'arme léger pouvant être servi en sécurité depuis l'habitacle du véhicule et ceci sans faire subir de lourdes modifications au véhicule.Thus, the invention makes it possible to equip an armored vehicle with a light weapon system that can be safely served from the passenger compartment of the vehicle without causing the vehicle to be heavily modified.

On notera à la figure 1 que la liaison pivot 4b entre le tube 2 et le support 4 est située en porte à faux par rapport à la nuque de tourelle. Ceci permet au tube 2 de pointer en hauteur sans que sa culasse ne vienne interférer avec la tourelle. Selon un autre mode de réalisation représenté à la figure 7, la liaison pivot 4b entre le tube 2 et le support 4 est situé en partie arrière du tube ce qui évite lors du relèvement du tube 2 d'éventuelles interférences avec des éléments du véhicule placés sous le dispositif 1.We will note in figure 1 that the pivot connection 4b between the tube 2 and the support 4 is located cantilevered with respect to the turret nape. This allows the tube 2 to point in height without its breech interferes with the turret. According to another embodiment shown in figure 7 , the pivot connection 4b between the tube 2 and the support 4 is situated at the rear part of the tube, which avoids, during the raising of the tube 2, any interference with elements of the vehicle placed under the device 1.
