Abstract

The present invention relates to a projectile, especially a shell, comprising subassemblies (11, 12, 13) forming a payload or submunitions, superposed axially, of dimensions corresponding to the calibre of the projectile, detachable and dispersible on the trajectory of the projectile under the effect of gas-generating dumping charges (39). It is characterised in that the gas-generating charges are connected to a single control means (33) by means of detonating cords (32). The gas-generating charges are arranged between each of the subassemblies or submunitions. Each of the gas-generating charges is placed in a containing chamber (28, 29, 30) which is delimited by two flanges (22, 23, 24) fixed to the ends of the adjacent subassemblies or submunitions and which has means for sealing against the generated gases. <IMAGE>

Description

La présente invention concerne un projectile, notamment un obus, qui peut être gyrostabilisé sur sa trajectoire, et qui est agencé pour disperser le long de cette trajectoire, ou un endroit prédéterminé de celle-ci, des sous-munitions ou des sous-ensembles constituant une charge utile. Ce type d'obus est communément appelé obus cargo. L'invention vise particulièrement un obus explosif de ce type.The present invention relates to a projectile, in particular a shell, which can be gyrostabilized on its trajectory, and which is arranged to disperse along this trajectory, or a predetermined location thereof, of the submunitions or of the subassemblies constituting a payload. This type of shell is commonly called a cargo shell. The invention particularly relates to an explosive shell of this type.

On connaît des projectiles porteurs de sous-munitions qui libèrent ou éjectent les sous-munitions sous l'action de gaz générés par des charges explosives de dépotage, soit par l'arrière, c'est-à-dire par cisaillement des moyens de liaison du culot et du corps du projectile, soit par l'avant, c'est-à-dire en désolidarisant l'ogive et en chassant les sous-munitions hors du corps du projectile par l'ouverture ainsi réalisée. Ces moyens de dépotage connus perturbent la trajectoire ultérieure des sous-munitions.We know of projectiles carrying submunitions which release or eject submunitions under the action of gases generated by explosive charges of stripping, either from the rear, that is to say by shearing of the connecting means the base and the body of the projectile, either from the front, that is to say by separating the warhead and driving the submunitions out of the body of the projectile through the opening thus produced. These known stripping means disrupt the subsequent trajectory of the submunitions.

Un dépotage par l'ogive provoque un freinage important du projectile, ce qui entraîne une mauvaise dispersion des sous-munitions gênante pour obtenir par exemple le minage d'une large zone de terrain.Stripping by the warhead causes significant braking of the projectile, which causes a poor dispersion of the annoying submunitions to obtain for example the mining of a large area of land.

Dans le cas d'un dépotage par le culot, il est indispensable de rendre solidaire le culot du corps du projectile par des goupilles cisaillables, et de disposer une charge génératrice de gaz au niveau de l'ogive. Ainsi, la pression des gaz engendrés par celle-ci s'exerce sur le culot par l'intermédiaire des sous-munitions et elle doit provoquer à la fois le cisaillement des goupilles de liaison et l'expulsion des sous-munitions. Il en résulte des contraintes qui, subies par les sous-munitions, peuvent être limitées par l'interposition nécessaire de chemises de protection.In the case of stripping by the base, it is essential to make the base integral with the body of the projectile by shearable pins, and to have a gas-generating charge at the level of the warhead. Thus, the pressure of the gases generated by it is exerted on the base via the submunitions and it must cause both the shearing of the connecting pins and the expulsion of the submunitions. This results in constraints which, undergone by the submunitions, can be limited by the necessary interposition of protective shirts.

Les frottements, dûs à l'effet centrifuge, entre sous-munitions chemisées ou non et corps de projectile, nécessite alors pour être surmontés une plus grande quantité de composition de dépotage. De plus, ce mouvement provoqué des sous-munitions, dans une direction opposée à celle du projectile, entraîne une vitesse réduite de celle-ci après dépotage, ce qui est préjudiciable à une bonne répartition des sous-munitions.The friction, due to the centrifugal effect, between jacketed or non-jacketed submunitions and projectile body, then requires to be overcome a greater amount of stripping composition. In addition, this movement caused by the submunitions, in a direction opposite to that of the projectile, results in a reduced speed of the latter after stripping, which is detrimental to a good distribution of the submunitions.

On connaît, par le brevet EP-A-0130893, un autre type d'obus cargo, adapté ici en particulier à la dispersion de mines, présentant un empilement de mines, muni d'un culot et d'une ogive, et qui constitue ainsi le corps même de l'obus. La solidarisation des différents éléments est réalisée au moyen d'un câble lié au culot et à l'ogive et dont la rupture commandée provoque la séparation des mines.We know, from patent EP-A-0130893, another type of cargo shell, adapted here in particular for dispersing mines, having a stack of mines, provided with a base and a warhead, and which constitutes thus the very body of the shell. The various elements are joined together by means of a cable linked to the base and to the warhead and the controlled rupture of which causes the mines to separate.

Mais, la libération simultanée de ces mines, dont les extrémités doivent par ailleurs présenter des formes rigoureusement complémentaires, limite la dispersion, donc l'efficacité sur une zone plus étendue. De plus, la réalisation pratique d'un câble de liaison capable de résister aux contraintes du coup de canon est très difficile.However, the simultaneous release of these mines, the ends of which must moreover have strictly complementary shapes, limits the dispersion, and therefore the effectiveness over a wider area. In addition, the practical realization of a connecting cable capable of withstanding the stresses of the cannon shot is very difficult.

On connaît aussi, par le brevet FR-A-2595810, un obus comportant des sous-munitions superposées au calibre, dont la séparation est obtenue au moyen de cordeaux de découpe agissant chacun sur une bague entretoise entre deux sous-munitions adjacentes. Mais ces cordeaux détonants de découpe, qui sont constitués par de petites charges creuses, sont actionnés séparément avec les inconvénients qui en résultent pour l'optimisation de la dispersion. De plus, ces charges creuses sont trop sensibles aux accélérations dues au coup de canon lors de la mise à feu d'un obus d'artillerie, et ces cordeaux de découpe peuvent être écrasés et détériorés sous l'effet de la force centrifuge. Enfin, ils peuvent induire des effets secondaires vers l'arrière qui risquent de détériorer les charges des sous-munitions au moment de la découpe.Also known, from patent FR-A-2595810, a shell comprising submunitions superimposed on the caliber, the separation of which is obtained by means of cutting cords each acting on a spacer ring between two adjacent submunitions. However, these detonating cutting cords, which consist of small hollow charges, are actuated separately with the resulting drawbacks for optimizing the dispersion. In addition, these shaped charges are too sensitive to accelerations due to the cannon shot when firing an artillery shell, and these cutting cords can be crushed and deteriorated under the effect of centrifugal force. Finally, they can induce rear side effects which could deteriorate the charges of the submunitions at the time of cutting.

Le brevet FR-A-2558585 montre le concept théorique d'un obus anti-char présentant des sous-munitions au calibre qui sont largables. Il n'est fait mention, qu'a titre d'exemple, que de la séparation au moyen d'un générateur de gaz logé entre deux sous-munitions. Mais il faut souligner que l'illustration schématique de ce concept montre deux sous-munitions juxtaposées et parfaitement jointives, sans donner d'enseignement sur la réalisation des moyens de solidarisation et de séparation de ces deux sous-munitions, dont on ne se préoccupe d'ailleurs pas de la dispersion. Ce document correspond au préambule de la revendication 1.The patent FR-A-2558585 shows the theoretical concept of an anti-tank shell having submunitions of caliber which are releasable. Mention is made, for example only, of separation by means of a gas generator housed between two submunitions. But it should be emphasized that the schematic illustration of this concept shows two juxtaposed and perfectly contiguous submunitions, without giving any instruction on the realization of the means of securing and separation of these two submunitions, which we are not concerned with. 'elsewhere not of the dispersion. This document corresponds to the preamble of claim 1.

Le brevet US-A-3 980 019 décrit une bombe aéroportée et non pas un projectile soumis au départ à une forte accélération. Cette bombe présente deux modes de fonctionnement soit pour disperser des sous-munitions, soit pour faire exploser l'ensemble. La dispersion des sous-munitions est obtenue à l'aide d'une fusée unique commandant simultanément l'initiation de quatre cordeaux de découpe de l'enveloppe de la bombe et d'un cordeau axial qui initie les charges de dispersion des sous-munitions.US-A-3,980,019 describes an airborne bomb and not a projectile subjected at the start to a strong acceleration. This bomb has two operating modes either to disperse submunitions or to detonate the whole. The dispersal of the submunitions is obtained using a single rocket simultaneously controlling the initiation of four lines cutting the shell of the bomb and an axial line which initiates the charges of dispersing the submunitions .

Le brevet GB-A-2 086 549 décrit un tube disperseur de sous-munitions, par exemple des mines ou des grenades. Une charge unique agit sur un disque de poussée pour assurer l'éjection de l'ensemble des charges hors du tube.GB-A-2,086,549 describes a dispersal tube for submunitions, for example mines or grenades. A single charge acts on a thrust disc to eject all of the charges from the tube.

Les brevets US-A-4 026 188 et FR-A-2 413 629 décrivent un dispositif permettant d'éjecter une par une des bouées acoustiques. Plusieurs dispositifs d'éjection identiques sont prévus, un par bouée, qui sont actionnés individuellement à partir d'un système de commande.The patents US-A-4 026 188 and FR-A-2 413 629 describe a device making it possible to eject acoustic buoys one by one. Several identical ejection devices are provided, one for each buoy, which are actuated individually from a control system.

La présente invention pallie les inconvénients relevés plus haut en proposant un projectile, notamment un obus, comportant plusieurs sous-projectiles ou sous-munitions au calibre, dont la séparation et la dispersion sont rigoureusement contrôlées et reproductibles. Un but de l'invention est de fournir des moyens de séparation tels que la vitesse initiale des sous-munitions, dès leur séparation, soit peu différente de la vitesse du projectile cargo lui-même, conduisant alors à une trajectoire qui assure une bonne dispersion de ces sous-ensembles.The present invention overcomes the drawbacks noted above by proposing a projectile, in particular a shell, comprising several sub-projectiles or submunitions of caliber, the separation and dispersion of which are rigorously controlled and reproducible. An object of the invention is to provide separation means such that the initial speed of the submunitions, as soon as they separate, is little different from the speed of the cargo projectile itself, then leading to a trajectory which ensures good dispersion of these subsets.

Pour ce faire, l'invention a pour objet un projectile, notamment un obus, comprenant des sous-ensembles constituant une charge utile ou des sous-munitions, superposés axialement, dimensionnés au calibre du projectile, désolidarisables et dispersables sur la trajectoire du projectile sous l'effet de charges de dépotage génératrices de gaz, caractérisé en ce que les charges génératrices de gaz sont disposées entre chacun des sous-ensembles ou sous-munitions et reliées à un moyen de commande unique par des cordeaux détonants et en ce que chacune des charges génératrices de gaz est placée dans une chambre de confinement qui est délimitée par deux flasques solidaires des extrémités des sous-ensembles ou sous-munitions adjacents, et qui comporte des moyens d'étanchéité aux gaz générés.To do this, the invention relates to a projectile, in particular a shell, comprising sub-assemblies constituting a payload or submunitions, axially superimposed, sized to the caliber of the projectile, separable and dispersible on the trajectory of the projectile under the effect of gas generating stripping charges, characterized in that the gas generating charges are arranged between each of the sub-assemblies or submunitions and connected to a single control means by detonating cords and in that each of the gas generating charges is placed in a containment chamber which is delimited by two flanges secured to the ends of the adjacent sub-assemblies or submunitions, and which comprises means for sealing against the gases generated.

Ainsi, selon l'invention, les moyens de solidarisation des sous-munitions empilés sont rompus séparément par des charges explosives de dépotage, commandées par exemple par la seule fusée du projectile, et reliées chacune à ce moyen de commande par un cordeau pyrotechnique détonant. L'adaptation de la longueur de ces cordeaux permet alors une séparation légèrement étalée le long de l'axe du projectile, pour améliorer la dispersion des sous-ensembles. Il faut noter que les cordeaux détonants utilisés, connus en eux-mêmes, sont constitués par des gaines de matière plastique enfermant des traces d'explosifs, et ont donc pour seule fonction celle de transmettre une onde de choc. Ils présentent l'avantage d être insensibles aux accélérations et à la force centrifuge.Thus, according to the invention, the means for securing the stacked submunitions are broken apart by explosive stripping charges, controlled for example by the only rocket of the projectile, and each connected to this control means by a detonating pyrotechnic cord. The adaptation of the length of these strings then allows a separation slightly spread out along the axis of the projectile, to improve the dispersion of the sub-assemblies. It should be noted that the detonating cords used, known in themselves, consist of plastic sheaths enclosing traces of explosives, and therefore have the sole function of transmitting a shock wave. They have the advantage of being insensitive to acceleration and centrifugal force.

Le projectile présente un cordeau détonant pénétrant dans au moins une chambre de confinement, de façon sensiblement axiale, le dispositif d'étanchéité étant constitué d'une part par un joint torique, s'appuyant sur les deux flasques, et d'autre part par une presse étoupe s'appuyant sur l'extrémité du cordeau détonant.The projectile has a detonating cord penetrating into at least one confinement chamber, in a substantially axial manner, the sealing device being constituted on the one hand by an O-ring, resting on the two flanges, and on the other by a cable gland resting on the end of the detonating cord.

Le projectile présente un cordeau détonant pénétrant dans une chambre de confinement, de façon sensiblement radiale, le dispositif d'étanchéité étant constitué par un joint annulaire déformable à flancs obliques, qui est traversé par le cordeau détonant, et qui coopère avec des portées coniques aménagées sur les flasques.The projectile has a detonating cord penetrating into a confinement chamber, in a substantially radial manner, the sealing device being constituted by a deformable annular seal with oblique sides, which is crossed by the detonating cord, and which cooperates with fitted conical surfaces. on the flanges.

Le projectile présente un cordeau détonant pénétrant dans une chambre de confinement, de façon sensiblement radiale, le dispositif d'étanchéité comprenant d'une part un couvercle, traversé par le cordeau détonant, apte à se déplacer sous l'effet de la pression des gaz de façon à venir sectionner le cordeau et à venir en contact au niveau d'une portée conique avec des flasques, et d'autre part un joint torique s'appuyant sur le couvercle et l'autre flasque.The projectile has a detonating cord penetrating into a confinement chamber, in a substantially radial manner, the sealing device comprising on the one hand a cover, traversed by the detonating cord, able to move under the effect of the pressure of the gases. so as to section the cord and to come into contact at the level of a conical surface with flanges, and on the other hand an O-ring bearing on the cover and the other flange.

Ainsi, chaque charge de dépotage n'agissant que sur un seul moyen de solidarisation de deux sous-ensembles adjacents, et voyant son rendement amélioré par des moyens d'étanchéité aux gaz malgré le passage nécessaire du cordeau, le projectile selon l'invention permet de mettre en oeuvre de très faibles quantités de composition de dépotage, ce qui participe par ailleurs aux buts énoncés plus haut, à savoir l'amélioration de la dispersion par réduction de la différence de vitesse entre le projectile et chacune des sous-munitions.Thus, each unloading charge acting on only one means of securing two adjacent sub-assemblies, and seeing its efficiency improved by means of gas tightness despite the necessary passage of the cord, the projectile according to the invention allows to implement very small quantities of stripping composition, which also contributes to the aims stated above, namely improving the dispersion by reducing the speed difference between the projectile and each of the submunitions.

D'autres avantages apparaîtront à la description suivante de modes de réalisation non limitatifs, en référence au dessin sur lequel :

  • les figures 1 et 2 sont respectivement une coupe schématique longitudinale et transversale d'un projectile ou obus cargo selon l'invention,
  • les figures 3 à 5 sont, à plus grande échelle, des schémas de divers moyens de séparation des sous-ensembles adjacents constitutifs de l'obus-cargo selon l'invention.
Other advantages will appear from the following description of nonlimiting embodiments, with reference to the drawing in which:
  • FIGS. 1 and 2 are respectively a schematic longitudinal and transverse section of a projectile or cargo shell according to the invention,
  • Figures 3 to 5 are, on a larger scale, diagrams of various means of separation of the adjacent subassemblies constituting the shell-cargo according to the invention.

Les figures 1 et 2 représentent un obus-cargo qui comprend, de façon connue, une fusée d'ogive 10, et un corps cylindrique constitué, dans cet exemple, de trois tronçons ou sous-munitions 11, 12 et 13, et fermé par un culot creux 14.Figures 1 and 2 show a cargo shell which comprises, in known manner, a warhead rocket 10, and a cylindrical body consisting, in this example, of three sections or submunitions 11, 12 and 13, and closed by a hollow base 14.

Les sous-munitions sont ici identiques et comportent, de façon connue, une charge explosive 15 amorcée par un amorçage central 16 relié par un cordeau détonant 17 à un dispositif de sécurité d'armement 18. Chaque sous-munition est donc autonome après sa séparation et son largage comme il est expliqué plus bas. Ces pots explosifs sont initiés et explosent dès leur arrivée au sol ; ils améliorent, par leur dispersion, l'efficacité destructive par rapport à un obus explosif conventionnel.The submunitions are identical here and comprise, in a known manner, an explosive charge 15 initiated by a central ignition 16 connected by a detonating cord 17 to an armament security device 18. Each submunition is therefore autonomous after its separation and its release as explained below. These explosive pots are initiated and explode upon their arrival on the ground; they improve, by their dispersion, the destructive efficiency compared to a conventional explosive shell.

Les corps des trois sous-munitions 11,12, 13, qui sont ici des pots explosifs, présentent un diamètre commun qui constitue donc le calibre de l'obus cargo, et participent à la rigidification de l'ensemble.The bodies of the three submunitions 11, 12, 13, which are here explosive pots, have a common diameter which therefore constitutes the caliber of the cargo shell, and participate in the stiffening of the assembly.

Les trois sous-munitions 11, 12 et 13 sont solidarisées deux à deux par des moyens de liaison 19 qui sont adaptés à la fonction de la charge utile qu'ils constituent. Les figures 1 et 2 montrent par exemple la solidarisation des tronçons 12 et 13, en rotation par des clavettes longitudinales 20 (ici au nombre de huit régulièrement réparties autour de la périphérie des tronçons), et en translation par des goupilles radiales 21, (ici au nombre de quatre par moyen de liaison). On doit noter que la séparation des sous-ensembles est facilitée par cette structure : les clavettes coulissent dans leurs logements, tandis que les goupilles présentent de préférence une faible résistance au cisaillement.The three submunitions 11, 12 and 13 are joined two by two by connecting means 19 which are adapted depending on the payload they constitute. Figures 1 and 2 show for example the joining of the sections 12 and 13, in rotation by longitudinal keys 20 (here eight in number regularly distributed around the periphery of the sections), and in translation by radial pins 21, (here four in number per link). It should be noted that the separation of the sub-assemblies is facilitated by this structure: the keys slide in their housings, while the pins preferably have a low shear strength.

Chaque sous-munition est fermée à ses extrémités par deux flasques, l'un 22 de type avant, l'autre 23 de type arrière, les sous-munitions d'extrémités 11 et 13 étant respectivement fermées par un flasque spécifique avant 24 qui vient coopérer avec l'extrémité arrière 25 de l'ogive 10, et par le culot 14 du projectile. Chaque flasque est rendu solidaire de sa sous-munition par filetage. Le flasque avant 22 est de préférence sa sous-munition fixé par des goupilles 26.Each submunition is closed at its ends by two flanges, one 22 of the front type, the other 23 of the rear type, the end submunitions 11 and 13 being respectively closed by a specific flange before 24 which comes cooperate with the rear end 25 of the warhead 10, and by the base 14 of the projectile. Each flange is made integral with its submunition by thread. The front flange 22 is preferably its submunition fixed by pins 26.

La figure 1 montre donc trois chambres de confinement 28, 29, 30 dont deux sont délimitées par chacun des flasques 22 et 23, et l'autre 30 par le flasque 24 et l'élément de liaison 25, formant extrémité arrière, de l'ogive 10.FIG. 1 therefore shows three confinement chambers 28, 29, 30, two of which are delimited by each of the flanges 22 and 23, and the other 30 by the flange 24 and the connecting element 25, forming the rear end of the warhead 10.

La charge utile est constituée ici par trois pots explosifs, chaque pot 15 tenant lieu de sous-munition ou de sous-ensemble au niveau d'un tronçon, logé entre deux flasques. Les pots sont liés en translation au corps de l'obus par les flasques eux-mêmes, et en rotation par filetage. L'explosif est collé au pot.The payload consists here of three explosive pots, each pot 15 serving as a submunition or sub-assembly at the level of a section, housed between two flanges. The pots are linked in translation to the body of the shell by the flanges themselves, and in rotation by threading. The explosive is stuck to the pot.

A l'intérieur des chambres 28, 29 et 30 sont fixées des petites charges génératrices de gaz 31, reliées chacune par des cordeaux détonants 32 à un moyen de commande unique, à savoir une fusée 33 logée dans l'ogive 10. La pression des gaz s'exerce à l'encontre des moyens de solidarisation, cisaillement des goupilles 21 et 26 par exemple, pour provoquer la séparation des trois tronçons. De préférence, la longueur des trois cordeaux détonants, par exemple ceux connus sous la dénomination commerciale "NONEL", est différente et choisie pour obtenir une séparation légérement étagée le long de l'axe du projectile, la sous-munition arrière étant par exemple larguée la première.Inside the chambers 28, 29 and 30 are fixed small gas-generating charges 31, each connected by detonating cords 32 to a single control means, namely a rocket 33 housed in the warhead 10. The pressure of the gas is exerted against the securing means, shearing of the pins 21 and 26 for example, to cause the separation of the three sections. Preferably, the length of the three detonating cords, for example those known under the trade name "NONEL", is different and chosen to obtain a separation slightly stepped along the axis of the projectile, the rear submunition being for example released first.

Dans une réalisation préférée, les cordeaux détonants 32 sont enroulés ensemble et noyés dans une résine 32a au niveau de l'ogive, c'est-à-dire entre la fusée d'ogive et la chambre de confinement avant, un tel enroulement permettant de jouer sur les longueurs respectives des différents cordeaux pour ajuster les instants de mises à feu des charges génératrices de gaz, et leur modulation d'échelonnement dans le temps.In a preferred embodiment, the detonating cords 32 are wound together and embedded in a resin 32a at the level of the warhead, that is to say between the warhead rocket and the front confinement chamber, such a winding making it possible to play on the respective lengths of the different cords to adjust the instants of ignition of the gas-generating charges, and their modulation over time.

Les figures 3 à 5 montrent diverses variantes de réalisation des chambres de confinement étanches contenant les charges de dépotage génératrices de gaz et des moyens de solidarisation des sous-munitions entre elles.Figures 3 to 5 show various alternative embodiments of the sealed containment chambers containing the gas-generating stripping charges and means for securing the submunitions to each other.

La figure 3 montre deux sous-munitions 11 et 12 constitués par des pots explosifs. Le tronçon 11, situé vers l'avant du projectile, est fermé à son extrémité arrière par vissage d'un flasque 23, formant couvercle et est donc entraîné en rotation de par le sens de l'hélice du filetage. Le tronçon 12 est fermé à son extrémité avant par un flasque 22, présentant lui aussi une collerette pour coopérer avec le flasque 23 pour délimiter une chambre de confinement 30. Le flasque 22 et 23 sont centrés l'un par rapport à l'autre par une goupille 34 enfilée dans des trous de clé à ergot du flasque 23. Chaque flasque est lié par filetage au tronçon 11 ou 12, et bloqué en rotation par une languette. La charge de dépotage 31 est fixée au centre de la chambre cylindrique 30. Elle est mise à feu par l'intermédiaire d'un relais 35 relié au cordeau détonant 32 qui débouche axialement au centre de la chambre par un orifice 36 pratiqué au centre du flasque 22, obturé par un presse-étoupe 37 présentant un joint d'étanchéité 37a. L'étanchéité est encore complétée par un joint torique 38 logé entre les bords emboîtés des flasques. Le cordeau détonant est maintenu noyé dans de la résine 39, et plaqué contre le flasque 22 par une fine tôle d'aluminium 40 collée sur le flasque 22, notamment pour éviter l'arrachement du cordeau pendant la phase d'accélération lors du départ du coup.Figure 3 shows two submunitions 11 and 12 consisting of explosive pots. The section 11, located towards the front of the projectile, is closed at its rear end by screwing a flange 23, forming a cover and is therefore driven in rotation by the direction of the helix of the thread. The section 12 is closed at its front end by a flange 22, also having a flange to cooperate with the flange 23 to delimit a confinement chamber 30. The flange 22 and 23 are centered relative to each other by a pin 34 threaded into lug wrench holes in the flange 23. Each flange is connected by thread to the section 11 or 12, and locked in rotation by a tongue. The unloading charge 31 is fixed to the center of the cylindrical chamber 30. It is ignited by means of a relay 35 connected to the detonating cord 32 which opens axially in the center of the chamber through an orifice 36 formed in the center of the flange 22, closed by a cable gland 37 having a seal 37a. The seal is further completed by an O-ring 38 housed between the nested edges of the flanges. The detonating cord is kept embedded in resin 39, and pressed against the flange 22 by a thin sheet of aluminum 40 bonded to the flange 22, in particular to avoid tearing the cord during the acceleration phase when the shot starts.

Ainsi, l'arrivée du cordeau détonant au centre de la charge de dépotage facilite son allumage, et évite un dispositif d'étanchéité sur le cordeau lui-même. Lors de la montée en pression, on garde alors la quantité maximum de gaz dans la chambre de confinement, de volume réduit, afin d'améliorer l'effort de séparation. Le flasque 22, qui présente une forme de réalisation simplifiée, est désolidarisé du flasque 23 par translation, après cisaillement des goupilles 21 et coulissement des clavettes 20. Ce mode de réalisation est particulièrement adapté à la solidarisation du sous-ensemble de tête avec l'ogive.Thus, the arrival of the detonating cord at the center of the unloading charge facilitates its ignition, and avoids a sealing device on the cord itself. When the pressure builds up, the maximum quantity of gas is then kept in the confinement chamber, of reduced volume, in order to improve the separation effort. The flange 22, which has a simplified embodiment, is separated from the flange 23 by translation, after shearing of the pins 21 and sliding of the keys 20. This embodiment is particularly suitable for securing the head sub-assembly with the warhead.

La figure 4 montre une variante de réalisation dans laquelle le cordeau détonant 32 débouche radialement sur la charge de dépotage 31 par l'intermédiaire d'un relais 35. Les deux flasques 22 et 23 présentent deux portées coniques 22a et 23a sur lesquelles vient prendre appui un joint 41 à flancs obliques. Le cordeau détonant est calé par une portée 42 en caoutchouc positionnée et collée sur le flasque 22. Ce dernier est solidarisé en rotation par une languette 43. Le joint 41 est fixé par trois pions en caoutchouc 41a s'engageant dans des trous correspondants pratiqués dans le flasque 22.FIG. 4 shows an alternative embodiment in which the detonating cord 32 opens radially onto the unloading charge 31 via a relay 35. The two flanges 22 and 23 have two conical surfaces 22a and 23a on which comes to bear a joint 41 with oblique sides. The detonating cord is wedged by a rubber seat 42 positioned and glued to the flange 22. The latter is secured in rotation by a tongue 43. The seal 41 is fixed by three rubber pins 41a engaging in corresponding holes made in the flange 22.

En fonctionnement, la pression des gaz écrase le joint 41 sur ses portées et obture le passage dans le joint du cordeau détonant qui est alors écrasé entre le flasque 22 et le joint 41. Les flasques sont séparés par écartement.In operation, the gas pressure crushes the seal 41 on its bearing surfaces and closes the passage in the joint of the detonating cord which is then crushed between the flange 22 and the seal 41. The flanges are separated by separation.

La figure 5 montre une troisième variante de réalisation des moyens de séparation de deux sous-munitions adjacentes 11 et 12. Les flasques 22 et 23 sont toujours solidarisés, par filetage respectivement aux sous-munitions 11 et 12. Un couvercle 45 est emboité sur le flasque plein 22 et retenu par une goupille radiale 44, pour délimiter avec lui la chambre de confinement 28. Comme dans la variante 35 précédente, le cordeau détonant 32 débouche radialement sur la charge de dépotage centrale 31 qui peut être par exemple une capsule de poudre noire, en étant calé par une portée 42 en caoutchouc collée sur le flasque 22, mais en traversant le bord du couvercle 45 par un orifice 46. Le bord du flasque 23 se termine par une butée conique annulaire 47. Un joint 48 assure l'étanchéité au niveau du centrage du flasque 22 et de son couvercle. Le flasque 22 est bloqué en rotation sur le corps du pot explosif 12 par une languette 49 pour tenir compte du sens du filetage. Le flasque 23 et son couvercle 45 sont solidarisés en rotation par la goupille 44. Le flasque 23 est solidarisé au pot 11 par vissage.FIG. 5 shows a third alternative embodiment of the means for separating two adjacent submunitions 11 and 12. The flanges 22 and 23 are always joined, by threading respectively to the submunitions 11 and 12. A cover 45 is fitted on the full flange 22 and retained by a radial pin 44, to delimit with it the confinement chamber 28. As in the previous variant 35, the detonating cord 32 opens radially onto the central unloading charge 31 which can for example be a powder capsule black, being wedged by a staff 42 in rubber bonded to the flange 22, but passing through the edge of the cover 45 through an orifice 46. The edge of the flange 23 ends in an annular conical stop 47. A seal 48 seals at the centering of the flange 22 and its cover. The flange 22 is locked in rotation on the body of the explosive container 12 by a tongue 49 to take account of the direction of the thread. The flange 23 and its cover 45 are secured in rotation by the pin 44. The flange 23 is secured to the pot 11 by screwing.

Après mise à feu de la charge 31, la pression monte et provoque le cisaillement de la goupille 44. Le couvercle 45 est alors séparé du flasque 22 et, poussé par les gaz, vient cisailler le cordeau détonant au niveau de son orifice de passage. Lorsque le couvercle arrive en appui contre la butée conique 47, le flasque 23 vient faire étanchéité sur les portées en écrasant le cordeau détonant tubulaire. Cette variante assure une étanchéité complète jusqu'au cisaillement des goupilles 21. La séparation est rapide et efficace par écartement des flasques.After firing the charge 31, the pressure rises and causes the pin 44 to shear. The cover 45 is then separated from the flange 22 and, pushed by the gases, shears the detonating cord at its passage orifice. When the cover comes to bear against the conical stop 47, the flange 23 seals on the surfaces by crushing the tubular detonating cord. This variant ensures complete sealing until the pins 21 are sheared. The separation is quick and effective by spacing the flanges.

Les exemples de réalisation des moyens de séparation et de confinement des gaz illustrés sur les figures 4 et 5 sont de préférence utilisés au niveau des sous-ensembles ou sous-munitions centraux ou arrière du projectile complet.The exemplary embodiments of the gas separation and confinement means illustrated in FIGS. 4 and 5 are preferably used at the level of the central or rear sub-assemblies or submunitions of the complete projectile.

Il faut souligner que l'architecture ainsi décrite permet de n'utiliser qu'une faible masse de composition génératrice de gaz.It should be emphasized that the architecture thus described makes it possible to use only a small mass of gas-generating composition.

Ainsi 10 grammes de poudre noire suffisent à provoquer la séparation de deux tronçons, alors qu'il faut au minimum 150 grammes de cette même composition pour pouvoir effectuer un dépotage de culot du type de ceux déjà décrits. Les pots suivent, après séparation, des trajectoires parallèles et leur vitesse initiale de l'ordre de celle de l'obus permet d'obtenir une plus large dispersion que celle qui pouvait être obtenue avec le dépotage de culot qui ne permettait d'obtenir pour ceux-ci qu'une vitesse de l'ordre de 200 m/s (soit une réduction d'environ 30% par rapport à la vitesse de l'obus).Thus 10 grams of black powder are sufficient to cause the separation of two sections, while at least 150 grams of this same composition are required in order to be able to decant a base of the type of those already described. The pots follow, after separation, parallel trajectories and their initial speed of the order of that of the shell allows to obtain a wider dispersion than that which could be obtained with the stripping of the base which did not allow to obtain for these only a speed of the order of 200 m / s (a reduction of about 30% compared to the speed of the shell).

Un étagement des séparations permet de répartir encore plus largement les trois pots, augmentant encore l'efficacité de l'obus.A staging of the partitions makes it possible to distribute the three pots even more widely, further increasing the efficiency of the shell.

L'invention décrite ici avec une charge utile constituée par des pots explosifs destinés à être initiés, au centre du chargement explosif, et à exploser dès leur arrivée au sol, permet donc d'obtenir une efficacité destructrice supérieure à celle obtenue avec un obus explosif conventionnel.The invention described here with a payload consisting of explosive pots intended to be initiated, at the center of the explosive charge, and to explode upon their arrival on the ground, therefore makes it possible to obtain a destructive efficiency greater than that obtained with an explosive shell. conventional.

On note aussi que le tronçon reste solidaire du pot explosif au cours de la chute et participe à l'effet vulnérant lors de l'explosion. Pour un autre type de charge utile, le mode de liaison charge-tronçon est choisi de façon à permettre la désolidarisation de ces deux éléments.We also note that the section remains attached to the explosive pot during the fall and contributes to the annoying effect during the explosion. For another type of payload, the link-section link mode is chosen so as to allow the separation of these two elements.

En variante, il est possible de remplacer les pots explosifs par toute autre charge utile telle que des mines, des charges éclairantes, des fumigènes, des grenades etc...As a variant, it is possible to replace the explosive pots with any other payload such as mines, lighting charges, smoke bombs, grenades, etc.
