Description

La présente invention se situe dans le domaine de la contre mesure passive infrarouge (I.R.) ou électromagnétique (E.M.) pour protéger des plate-formes telle que des aéronefs légers ou des hélicoptères lorsqu'ils sont menacés par des missiles équipés par exemple d'autodirecteur IR ou EM, c'est à dire de système de guidage fonctionnant dans le domaine infrarouge ou électromagnétique. Cette protection se fait en attirant le missile à l'écart de la plate-forme à l'aide de leurres infrarouge ou électromagnétique.The present invention is in the field of passive infrared (IR) or electromagnetic (EM) countermeasures to protect platforms such as light aircraft or helicopters when they are threatened by missiles equipped for example with seeker IR or EM, that is to say a guidance system operating in the infrared or electromagnetic field. This protection is done by attracting the missile away from the platform using infrared or electromagnetic decoys.

La présente invention concerne plus particulièrement des cartouches pyrotechniques contenant une pluralité de charges utiles ; après éjection, la combustion de ces charges utiles crée un rayonnement infrarouge assimilable à la signature infrarouge de la plate-forme à protéger, ou après éjection, la dispersion de ces charges utiles dans l'atmosphère crée un écho radar assimilable à la surface équivalente radar (S.E.R.) de la plate-forme à protéger. Le système de guidage du missile est leurré par ce dispositif et le missile se trouve écarté de la plate-forme visée.The present invention relates more particularly to pyrotechnic cartridges containing a plurality of payloads; after ejection, the combustion of these payloads creates an infrared radiation comparable to the infrared signature of the platform to be protected, or after ejection, the dispersion of these payloads in the atmosphere creates a radar echo comparable to the equivalent radar surface (SER) of the platform to be protected. The missile guidance system is deceived by this device and the missile is moved away from the target platform.

La présente invention concerne aussi la munition équipée des dites cartouches. Elle est placée dans un lance-leurres fixé sur la plate-forme à protéger, le lance-leurres est relié au boîtier de commande de tir. La munition comprend un casier recevant les dites cartouches, une platine qui assure d'une part la fermeture du casier et d'autre part comporte les connexions électriques avec le lance-leurres et les contacts électriques avec les cartouches.The present invention also relates to the ammunition equipped with said cartridges. It is placed in a decoy launcher fixed on the platform to be protected, the decoy launcher is connected to the fire control unit. The ammunition comprises a locker receiving the said cartridges, a plate which ensures on the one hand the closing of the locker and on the other hand comprises the electrical connections with the decoy launcher and the electrical contacts with the cartridges.

La présente invention concerne aussi une munition équipée des dites cartouches et qui fait office de lance-leurres : cette munition se fixe directement sur la plate-forme et est reliée au boîtier de commande de tir.The present invention also relates to an ammunition equipped with said cartridges and which acts as a decoy launcher: this ammunition is fixed directly on the platform and is connected to the fire control unit.

Les cartouches connues à ce jour comportent une charge utile ou plusieurs charges utiles disposées en série.The cartridges known to date include a payload or several payloads arranged in series.

Dans le domaine de l'infrarouge, les charges utiles sont des pains de substance pyrotechnique fabriqués à partir de compositions peu performantes, ces pains auront donc une taille relativement importante pour produire une signature infrarouge équivalente à celle de la plate-forme à protéger.In the infrared field, the payloads are buns of pyrotechnic substance made from inefficient compositions, these buns will therefore have a relatively large size to produce an infrared signature equivalent to that of the platform to be protected.

Les inconvénients qui en résultent sont la taille importante des cartouches ce qui limite leur nombre pour un encombrement donné de la munition. Les charges d'éjection doivent être importantes ce qui implique un fort recul au départ du coup et nécessite des pièces (telles que le casier ou la platine) renforcées et donc plus lourdes.The resulting drawbacks are the large size of the cartridges, which limits their number for a given size of the ammunition. The ejection charges must be high, which implies a strong recoil at the start of the shot and requires reinforced parts (such as the locker or the plate) and therefore heavier.

Dans les munitions du type ci-dessus décrit et connues à ce jour les cartouches sont fixées une à une dans le casier par des vis ou des anneaux d'arrêt élastiques (circlips) ; de même la platine ferme le casier par vissage. Les inconvénients de tels dispositifs sont la difficulté du chargement qui nécessite un outillage plus ou moins spécifique, et la durée de ce chargement due aux nombreuses manipulations. Dans ces conditions le rechargement du casier n'est pas possible sur le site d'opérations.In ammunition of the type described above and known to date the cartridges are fixed one by one in the rack by screws or elastic stop rings (circlips); likewise the plate closes the locker by screwing. The disadvantages of such devices are the difficulty of loading which requires more or less specific tools, and the duration of this loading due to the numerous manipulations. Under these conditions, reloading the locker is not possible on the site of operations.

Pour s'affranchir de ces inconvénients, un but de l'invention est de réduire la dimension des cartouches et d'optimiser leur rangement pour augmenter le nombre de coups disponibles pour un même encombrement de la munition et pour un même effet de leurrage (signature infrarouge et surface équivalente radar).To overcome these drawbacks, an object of the invention is to reduce the size of the cartridges and optimize their storage to increase the number of shots available for the same size of the ammunition and for the same decoy effect (infrared signature and equivalent radar surface).

Un autre but de l'invention est de simplifier l'opération de chargement ou de rechargement pour qu'elle se fasse sans recours à un outillage et en un nombre limité de manipulations pour réduire considérablement la durée de cette opération : le rechargement sur site opérationnel, ou à proximité immédiate, est ainsi réalisable.Another object of the invention is to simplify the loading or reloading operation so that it is done without the use of tools and in a limited number of manipulations to considerably reduce the duration of this operation: reloading on operational site , or in the immediate vicinity, is thus achievable.

La cartouche selon l'invention contient une pluralité de charges utiles qui sont éjectées par des moyens pyrotechniques. La cartouche est constituée d'une semelle solidaire d'un étui dans lequel se logent une pluralité d'ensembles comprenant des charges pyrotechniques d'éjection, des ensembles pyromécaniques, des charges d'allumage, des charges utiles et des opercules. La cartouche est caractérisée en ce que l'étui est muni de plusieurs logements et comporte à sa base un dispositif de blocage dans un casier, les ensembles précités sont indépendants et sont disposés en parallèle dans les différents logements de l'étui, la semelle est commune aux différents logements et comporte des amorces électriques. Le dispositif pyromécanique comporte un retard pyrotechnique et des sécurités de fonctionnement pour initier la charge d'allumage qui va à son tour initier la combustion de la charge utile, les sécurités interrompent cette chaîne en cas d'anomalies de fonctionnement (ensemble non éjectée par exemple).The cartridge according to the invention contains a plurality of payloads which are ejected by pyrotechnic means. The cartridge consists of a sole integral with a case in which are housed a plurality of assemblies comprising pyrotechnic ejection charges, pyromechanical assemblies, ignition charges, payloads and lids. The cartridge is characterized in that the case is provided with several housings and comprises at its base a blocking device in a locker, the above-mentioned assemblies are independent and are arranged in parallel in the various housings of the case, the sole is common to the various dwellings and includes electric primers. The pyromechanical device includes a pyrotechnic delay and operating safety devices to initiate the ignition charge which will in turn initiate the combustion of the payload, the safety devices interrupt this chain in the event of operating anomalies (assembly not ejected for example ).

Préférentiellement le dispositif de blocage de la cartouche dans le casier est constitué par un bourrelet situé à la base de l'étui. Par base de l'étui, on entend le côté de l'étui situé près de la semelle. Ce bourrelet assure de plus l'étanchéité entre le casier et la cartouche.Preferably, the device for blocking the cartridge in the locker consists of a bead located at the base of the case. By case base is meant the side of the case located near the sole. This bead also provides sealing between the rack and the cartridge.

Avantageusement le dispositif de blocage de la cartouche dans le casier est constitué par un joint, logé dans une gorge située à la base de l'étui. Ce joint assure de plus l'étanchéité entre le casier et la cartouche.Advantageously, the device for blocking the cartridge in the crate consists of a seal, housed in a groove located at the base of the case. This seal also provides a seal between the rack and the cartridge.

L'étui de la cartouche selon l'invention comporte un nombre impair de logements. Le mode de positionnement dans le casier est indifférent. Préférentiellement le nombre de logements de l'étui est égal à trois.The cartridge case according to the invention has an odd number of housings. The positioning mode in the rack is indifferent. Preferably, the number of housings in the case is three.

Selon un mode de réalisation préféré la cartouche selon l'invention est telle que l'étui est constitué de plusieurs logements réalisés par moulage-injection sur la semelle d'une matière plastique chargée. Avantageusement cette matière plastique est conductrice de l'électricité.According to a preferred embodiment, the cartridge according to the invention is such that the case consists of several housings produced by injection molding on the sole of a charged plastic material. Advantageously, this plastic material is electrically conductive.

Pour une forme particulière de réalisation de l'invention, la charge utile de l'ensemble précité est constituée par un pain de substance pyrotechnique à fort rayonnement dans l'infrarouge lors de sa combustion. Par fort rayonnement, il faut entendre un rayonnement égal ou supérieur à 60 J par gramme de substance brûlée, cette énergie étant mesurée dans la bande II de 3 à 5 µm.For a particular embodiment of the invention, the payload of the aforementioned assembly is constituted by a bread of pyrotechnic substance with strong radiation in the infrared during its combustion. By strong radiation is meant radiation equal to or greater than 60 J per gram of substance burned, this energy being measured in band II from 3 to 5 µm.

Pour une autre forme de réalisation de l'invention, la charge utile de l'ensemble précité est constituée par des produits aptes à créer un écho radar lorsqu'ils sont dispersés dans l'atmosphère, après éjection. Les produits sont des paillettes ou des fibres métalliques ou métallisées, ils sont connus dans l'état de la technique.For another embodiment of the invention, the payload of the above-mentioned assembly consists of products capable of creating a radar echo when they are dispersed in the atmosphere, after ejection. The products are flakes or metallic or metallized fibers, they are known in the state of the art.

Le casier, chargé de ses cartouches, est fixé sur la platine. Cette platine réalise la fermeture du casier, elle permet l'identification de la nature des charges utiles des cartouches (charge utile produisant un rayonnement infrarouge ou créent un écho-radar) par des dispositifs connus dans l'état de la technique. Cette platine réalise aussi la connexion électrique entre la plateforme qui reçoit la munition et les amorces des cartouches.The locker, loaded with its cartridges, is fixed on the plate. This plate closes the locker, it allows the identification of the nature of the payloads of the cartridges (payload producing infrared radiation or creating an echo-radar) by devices known in the state of the art. This plate also makes the electrical connection between the platform which receives the ammunition and the cartridges primers.

La munition comprenant une platine ainsi qu'un casier monobloc, est telle que ce casier comporte des alvéoles destinées à recevoir et bloquer les cartouches telles que précèdemment décrites.The ammunition comprising a plate as well as a monobloc rack, is such that this rack comprises cells intended to receive and block the cartridges as previously described.

Avantageusement la munition selon l'invention contient simultanément des cartouches de charges utiles rayonnant dans l'infrarouge et des cartouches de charges utiles aptes à produire un écho radar.Advantageously, the munition according to the invention simultaneously contains cartridges of payloads radiating in the infrared and cartridges of payloads capable of producing a radar echo.

Avantageusement aussi la munition reçoit des cartouches dont la longueur est supérieure à la profondeur des alvéoles du casier. Cette disposition permet un déchargement rapide du casier.Advantageously also the ammunition receives cartridges whose length is greater than the depth of the cells of the rack. This arrangement allows rapid unloading of the locker.

Selon un mode préféré de réalisation de la munition le casier monobloc chargé de ses cartouches est fixé sur la platine au moyen d'un système de fermeture comportant au moins une charnière rapide.According to a preferred embodiment of the ammunition, the monobloc rack loaded with its cartridges is fixed to the plate by means of a closing system comprising at least one quick hinge.

Avantageusement la fermeture de la platine sur le casier est réalisée par au moins une charnière rapide et un cliquet.Advantageously, the closing of the plate on the rack is carried out by at least one quick hinge and a pawl.

Préférentiellement le casier comporte une poignée escamotable pour la manutention de la munition et pour commander le déverrouillage de la munition du lance-leurres.Preferably, the locker comprises a retractable handle for handling the ammunition and for controlling the unlocking of the munition of the decoy launcher.

Avantageusement cette munition comporte un premier joint disposé à l'arrière du casier, il assure l'étanchéité entre le casier et la platine de fermeture; et un deuxième joint, placé autour du casier, il assure l'étanchéité entre le casier et le lance-leurres.Advantageously, this ammunition comprises a first seal disposed at the rear of the rack, it provides sealing between the rack and the closing plate; and a second seal, placed around the crate, it seals between the crate and the decoy launcher.

Dans une réalisation particulière de la munition, le casier chargé de ses cartouches et fixé sur sa platine se monte directement sur la plate-forme à protéger : c'est-à-dire que la munition ne se fixe pas dans un lance-leurres, elle constitue elle-même le lance-leurres. Elle est fixée sur l'aéronef par des broches, ou des étriers, ou tout autre dispositif existant sur l'aéronef. Elle se raccorde au poste de tir par un cable et un connecteur qui se branche à un connecteur disposé sur la platine, par exemple à une de ses extrémités.In a particular embodiment of the munition, the rack loaded with its cartridges and fixed on its plate is mounted directly on the platform to protect: that is to say that the ammunition is not fixed in a decoy launcher, it constitutes itself the decoy launcher. It is fixed to the aircraft by pins, or stirrups, or any other device existing on the aircraft. It is connected to the shooting station by a cable and a connector which is connected to a connector arranged on the plate, for example at one of its ends.

Préférentiellement le casier est profilé aérodynamiquement ce qui réduit la trainée due à la munition accrochée sur la plate-forme.Preferably, the rack is aerodynamically profiled, which reduces the drag due to the ammunition hung on the platform.

Le profilage aérodynamique du casier comprend un carénage arrondi pour le bord d'attaque et un carénage en forme de dièdre au bord de fuite. De préférence ces carénages de bord d'attaque et du bord de fuite peuvent s'étendre sur toute la hauteur des cartouches. Avantageusement le casier peut constituer un carénage latéral de hauteur égale à celle des cartouches.The aerodynamic profiling of the locker includes a rounded fairing for the leading edge and a dihedral-shaped fairing at the trailing edge. Preferably these leading edge and trailing edge fairings can extend over the entire height of the cartridges. Advantageously, the rack can constitute a side fairing of height equal to that of the cartridges.

Avantageusement dans une partie du carénage du bord de fuite on crée une ouverture oblongue de façon à réaliser une poignée de manutention intégrée au casier. Les différentes arêtes vives sont chanfreinées ou arrondies pour rendre cette poignée commode à utiliser.Advantageously, in a part of the trailing edge fairing, an oblong opening is created so as to produce a handling handle integrated into the rack. The different sharp edges are chamfered or rounded to make this handle convenient to use.

Selon un mode préféré de fabrication le casier des munitions est réalisé par moulage-injection d'une matière plastique chargée. Avantageusement cette matière plastique est conductrice de l'électricité.According to a preferred mode of manufacture, the ammunition bin is produced by injection molding of a charged plastic material. Advantageously, this plastic material is electrically conductive.

Dans ce qui suit l'invention est exposée plus en détail à l'aide de figures représentant une réalisation particulière.In what follows the invention is explained in more detail with the aid of figures representing a particular embodiment.

La figure 4 est une vue détaillée de la partie A de la figure 2.FIG. 4 is a detailed view of part A of FIG. 2.

La figure 5 représente une vue en perspective, partiellement éclatée, d'une munition, faisant lance-leurres.Figure 5 shows a perspective view, partially exploded, of an ammunition, making decoy launchers.

La figure 1 représente une cartouche 1 dont la charge utile 9 est un pain de substance pyrotechnique rayonnant dans l'infrarouge lors de sa combustion. Cette cartouche comporte une semelle 2 et un étui 3. Cet étui 3 comporte à son talon (extrémité du côté de la semelle) et sur toute sa périphérie extérieure un bourrelet 4. La semelle 2 reçoit les amorces électriques 5, une pour chacun des logements de l'étui. Dans chaque logement on trouve (à la suite de l'amorce électrique 5) une charge d'éjection 6, un ensemble pyromécanique 7 (retard pyrotechnique et sécurités de fonctionnement), une charge d'allumage 8, la charge utile 9, enfin le logement est fermé de façon étanche par un opercule 10.FIG. 1 represents a cartridge 1 whose payload 9 is a loaf of pyrotechnic substance radiating in the infrared during its combustion. This cartridge comprises a sole 2 and a case 3. This case 3 has at its heel (end on the side of the sole) and over its entire outer periphery a bead 4. The sole 2 receives the electrical primers 5, one for each of the housings from the case. In each housing there is (following the electric primer 5) an ejection charge 6, a pyromechanical assembly 7 (pyrotechnic delay and operating safety), an ignition charge 8, the payload 9, finally the housing is tightly closed by a cover 10.

Lorsque la charge utile 9 est du type électromagnétique l'ensemble 11 est réduit à une charge d'éjection 6 ; le dispositif pyromécanique est remplacé par un simple piston assurant l'éjection de la charge utile 9. Cette charge utile est constituée par des paillettes ou des fibres métalliques ou métallisées, le logement est fermé de façon étanche par un opercule 10.When the payload 9 is of the electromagnetic type, the assembly 11 is reduced to an ejection charge 6; the pyromechanical device is replaced by a simple piston ensuring the ejection of the payload 9. This payload consists of flakes or metallic or metallized fibers, the housing is closed in leaktight manner by a cover 10.

L'étui 3 et le bourrelet 4 sont dans cet exemple réalisés par moulage-injection autour de la semelle 2 en d'un polyéther chargé de fibres de verre et rendu conducteur.The case 3 and the bead 4 are in this example produced by injection molding around the sole 2 in of a polyether loaded with glass fibers and made conductive.

Le pain de substance pyrotechnique rayonnante est fabriqué à partir d'une compostion magnésium-polytétrafluoroéthylène-époxy mise en oeuvre par compression ou extrusion. Ce pain est à combustion externe, ou interne lorsqu'il comporte un canal central.The bread of radiant pyrotechnic substance is made from a magnesium-polytetrafluoroethylene-epoxy composition implemented by compression or extrusion. This bread is for external combustion, or internal when it has a central channel.

La charge d'allumage 8 est une composition magnésium-polytétrafluoroéthylène-élastomère fluoré.The ignition charge 8 is a magnesium-polytetrafluoroethylene-fluorinated elastomer composition.

L'impulsion électrique délivrée par le lance-leurres initie l'amorce électrique 5 ; cette amorce est du type "1 ampère - 1 watt - 5 minutes non feu" existant sur catalogue. Cette dernière allume la charge d'éjection 6 qui d'une part éjecte, hors d'un logement de l'étui 3, l'empilement 11 : ensemble pyromécanique 7, charge d'allumage 8, charge utile 9 et opercule 10 et d'autre part assure l'allumage d'un retard pyrotechnique incorporé à l'ensemble pyromécanique 7.The electric pulse delivered by the decoy launcher initiates the electric primer 5; this primer is of the type "1 ampere - 1 watt - 5 minutes flame retardant" existing on the catalog. The latter ignites the ejection charge 6 which on the one hand ejects, from a housing of the case 3, the stack 11: pyromechanical assembly 7, ignition charge 8, payload 9 and seal 10 and d on the other hand ensures the ignition of a pyrotechnic delay incorporated in the pyromechanical assembly 7.

A la sortie de l'étui 3, un dispositif de sécurité de bouche, faisant partie de l'ensemble pyromécanique 7, réalise l'alignement entre le retard pyrotechnique et la charge d'allumage 8 et cette dernière assure ensuite la mise en combustion du pain de substances pyrotechnique constituant la charge utile 9. L'alignement entre le retard pyrotechnique et la charge d'allumage 8, est interrompu par un autre dispositif de sécurité si l'ensemble "dispositif pyromécanique-charge d'allumage et charge utile" rencontre un obstacle à proximité du point d'éjection. Les dispositifs de sécurité précédemment cités sont du type de ceux habituellement utilisés dans ce domaine.At the outlet of the case 3, a mouth safety device, forming part of the pyromechanical assembly 7, realizes the alignment between the pyrotechnic delay and the ignition charge 8 and the latter then ensures the combustion of the loaf of pyrotechnic substances constituting the payload 9. The alignment between the pyrotechnic delay and the ignition charge 8 is interrupted by another safety device if the assembly "pyromechanical device-ignition charge and payload" meets an obstacle near the ejection point. The security devices mentioned above are of the type usually used in this field.

La figure 2 représente la munition 20 constituée par un casier 21 qui reçoit les cartouches 1, sur cette figure on compte 24 cartouches constituées chacune de trois lobes et comportant trois logements ce qui représentent 72 coups disponibles. Le casier 21 est fermé par la platine 22. La poignée escamotable 23 (représentée en position ouverte) sert à la manutention de la munition, elle commande aussi le dispositif de déverrouillage de la munition et du lance-leurres. La platine 22 s'articule et se fixe sur le casier par une charnière rapide 25.FIG. 2 represents the ammunition 20 constituted by a rack 21 which receives the cartridges 1, in this figure there are 24 cartridges each consisting of three lobes and comprising three housings which represent 72 strokes available. The locker 21 is closed by the plate 22. The retractable handle 23 (shown in the open position) is used for handling the ammunition, it also controls the device for unlocking the ammunition and the decoy launcher. The plate 22 is articulated and fixed on the rack by a quick hinge 25.

L'agrandissement représenté à la figure 4 montre le détail de cette partie : la patte 26 solidaire de la platine comporte une fente oblongue, débouchante et inclinée par rapport à l'axe de la patte ; cette fente s'engage dans un pion 27 solidaire du casier 21, ce pion constitue l'axe de rotation de la charnière. Dans l'exemple présenté la platine comporte deux charnières identiques disposées aux extrémités d'un même côté de la platine. La platine est fermée et verrouillée sur le casier par le cliquet élastique 28 solidaire du casier dans cet exemple. Cette fabrication simple et légère est réalisable par suite du faible effort de recul lors du fonctionnement des cartouches.The enlargement shown in Figure 4 shows the detail of this part: the tab 26 secured to the plate has an oblong slot, emerging and inclined relative to the axis of the tab; this slot engages in a pin 27 integral with the rack 21, this pin constitutes the axis of rotation of the hinge. In the example presented, the plate has two identical hinges arranged at the ends of the same side of the plate. The plate is closed and locked on the locker by the elastic pawl 28 secured to the locker in this example. This simple and light manufacturing is achievable due to the low recoil force during the operation of the cartridges.

Sur la figure 3 on voit le casier 21 (la platine 22 est retirée) toutes les cartouches sont en place sauf une qui est représentée partiellement engagée dans l'alvéole 29 dont on voit la forme appropriée au logement des cartouches 1. Le bourrelet 4 de la cartouche 1 réalise un forcement suffisamment important pour empêcher la cartouche de retomber au cas ou le casier serait renversé, mais suffisamment faible pour que ce forcement se fasse manuellement. Les alvéoles 29 du casier ont, à leur extrémité arrière, un épaulement qui sert de butée au talon de la cartouche.In Figure 3 we see the rack 21 (the plate 22 is removed) all the cartridges are in place except one which is shown partially engaged in the cell 29 which we see the shape suitable for housing the cartridges 1. The bead 4 of the cartridge 1 performs a sufficiently large forcing to prevent the cartridge from falling back in case the locker is overturned, but weak enough for this forcing to be done manually. The cells 29 of the crate have, at their rear end, a shoulder which serves as a stop for the heel of the cartridge.

D'autre part les cartouches ont une longueur supérieure à la profondeur du casier et débordent sur la face avant du casier lorsqu'elles sont en butée sur l'épaulement. Cette disposition permet de les extraire très rapidement pour les retirer du casier. Lorsque la platine est enlevée, il suffit de pousser sur la partie sortante de la cartouche pour la faire glisser hors de l'alvéole (on débloque ainsi le bourrelet) on retire alors la cartouche de l'alvéole.
La figure 5 représente un exemple de réalisation de l'invention où la munition 30 constitue aussi le lance-leurres : la munition se fixe directement sur la plateforme à protéger et est reliée par un cable électrique au poste de commande de tir.
La munition est représentée partiellement démontée, on trouve :

  • la casier 31 équipé, dans cet exemple, de deux rangées de six cartouches tel les que précèdemment décrites ; seule une dernière cartouche 1 est représentée non engagée dans l'avéole 39 destinée à la recevoir,
  • la platine 32 : réalise d'une part la fermeture du casier et d'autre part les contacts électriques avec les amorces des cartouches, l'une des extrémités de la platine comporte un connecteur 33 sur lequel se branche le cable assurant la liaison avec le poste de tir,
  • les broches 34 fixent d'une part la platine sur le casier et d'autre part servent à fixer la munition sur la plate-forme à protéger.
On the other hand, the cartridges have a length greater than the depth of the rack and extend beyond the front face of the rack when they are in abutment on the shoulder. This arrangement allows them to be extracted very quickly to remove them from the locker. When the plate is removed, it is enough to push on the outgoing part of the cartridge to make it slide out of the alveolus (one thus unblocks the bead) one then withdraws the cartridge from the alveolus.
FIG. 5 represents an exemplary embodiment of the invention where the ammunition 30 also constitutes the decoy launcher: the ammunition is fixed directly on the platform to be protected and is connected by an electric cable to the fire control station.
The ammunition is shown partially disassembled, there are:
  • the rack 31 equipped, in this example, with two rows of six cartridges such as those previously described; only a last cartridge 1 is shown not engaged in the nozzle 39 intended to receive it,
  • the plate 32: on the one hand closes the locker and on the other hand the electrical contacts with the primers of the cartridges, one of the ends of the plate comprises a connector 33 on which the cable is connected ensuring the connection with the shooting post,
  • the pins 34 fix on the one hand the plate on the rack and on the other hand serve to fix the ammunition on the platform to be protected.

Le casier est de réalisation identique à celle de l'exemple précédemment décrit notamment en ce qui concerne la forme et les dimensions des alvéoles 39 (profondeur des avéoles 39 inférieure à la longueur des cartouches 1). Comme dans l'exemple précédent ce casier est fabriqué par moulage-injection.
Toutefois la fixation de la platine 32 sur le casier 31 se fait ici différemment. La dite platine 32 s'engage dans une alvéole 38 à la base de casier et les broches 34 viennent la fixer sur le casier.The crate is identical to that of the example previously described in particular with regard to the shape and dimensions of the cells 39 (depth of the cells 39 less than the length of the cartridges 1). As in the previous example, this rack is produced by injection molding.
However, the fixing of the plate 32 on the rack 31 is done here differently. Said plate 32 engages in a cell 38 at the base of the rack and the pins 34 come to fix it on the locker.

Enfin le casier est profilé. Ce profilage est réalisé de façon très simple par une forme arrondie 35 sur le bord d'attaque et par une forme en dièdre aigu 36 sur le bord de fuite. De plus dans le bord de fuite est pratiqué une ouverture oblongue 37 : on a ainsi une poignée de manutention incorporée au casier ; les différentes arêtes sont chanfreinées ou arrondies pour rendre commode l'usage de cette poignée.Finally the locker is profiled. This profiling is carried out very simply by a rounded shape 35 on the leading edge and by an acute dihedral shape 36 on the trailing edge. In addition, in the trailing edge there is an oblong opening 37: there is thus a handling handle incorporated in the rack; the different edges are chamfered or rounded to make it convenient to use this handle.
