Description

CHARGE ANTI MISSILE A BARREAUX DEPLOYABLES PAR RESTITUTION D'ENERGIE ET  ANTI-MISSILE LOAD WITH DEPLOYABLE BARS BY ENERGY RESTITUTION AND
PROCEDE D'ACTIVATION D'UNE TELLE CHARGE  METHOD FOR ACTIVATION OF SUCH CHARGE
L'invention concerne les charges antimissiles à faisceau de barreaux déployables compatibles des modes de fonctionnement tels que ceux à effet dirigé et à effet axisymétrique. La figure 1 a montre un exemple de charge antimissile à barreaux de l'état de l'art désignée aussi par l'acronyme ATBM pour « Anti Tactical Ballistic Missile » en langue anglaise. The invention relates to deployable bar-beam missile loads compatible with modes of operation such as those with directed effect and axisymmetric effect. FIG. 1a shows an example of a state-of-the-art anti-ballistic missile load also designated by the acronym ATBM for "Anti Tactical Ballistic Missile" in the English language.
La charge de la figure 1 a comporte essentiellement un fagot 10 de barreaux 12, généralement en tungstène, autour d'un axe longitudinal XX' de la charge. Le fagot 10 est entouré d'un certain nombre de secteurs d'explosifs E1 , E2, ... Ei, .. En, dans l'exemple de la figure 1 , n est égal à 7.  The load of Figure 1 has essentially a bundle 10 of bars 12, generally made of tungsten, about a longitudinal axis XX 'of the load. The bundle 10 is surrounded by a certain number of explosive sectors E1, E2,... E1, .. In, in the example of FIG. 1, n is equal to 7.
Les figures 1 b et 1 c montrent le fonctionnement de la charge ATBM de la figure 1 a dans un mode d'utilisation dit à effet dirigé.  FIGS. 1b and 1c show the operation of the ATBM load of FIG. 1a in a so-called directed effect mode of use.
Lorsqu'une cible C, par exemple un missile balistique, se déplaçant selon l'axe ZZ', est détectée, dans un premier temps, un certain nombre de secteurs d'explosifs de la charge ATBM du côté de la cible C sont expulsés ou éloignés du fagot 10 de manière à faciliter le déploiement des barreaux 12 dans la direction de la cible (voir figure 1 b). En suite, au moins un secteur d'explosif de la charge opposé à la cible C est initié (secteur grisé E2 sur la figure 1 c) pour générer un déploiement des barreaux autour d'un axe MM' dirigé de la charge vers la cible (voir figure 1 c).  When a target C, for example a ballistic missile, moving along the axis ZZ ', is detected, at first, a number of explosive sectors of the ATBM load on the side of the target C are expelled or remote from the bundle 10 so as to facilitate the deployment of the bars 12 in the direction of the target (see Figure 1 b). Next, at least one explosive sector of the charge opposite the target C is initiated (shaded area E2 in FIG. 1c) to generate a deployment of the bars around an axis MM 'directed from the load towards the target (see Figure 1c).
Si les temps d'intersection le permettent, les secteurs d'explosifs peuvent être remplacés par des matériaux énergétiques au rendu d'énergie moins violent que la détonation (déflagration ou combustion)  If the intersection times allow it, the explosive sectors can be replaced by energetic materials with energy rendering less violent than the detonation (deflagration or combustion).
Un deuxième mode de fonctionnement de la charge ATBM, de plus en plus utilisé dû à la plus grande précision de pilotage et guidage des missiles intercepteurs modernes porteurs de la charge, consiste à obtenir un mode de déploiement des barreaux de manière axisymétrique, l'axe de déploiement des barreaux étant l'axe longitudinal XX' de la charge. La figure 2a montre un autre exemple de charge ATBM de l'état de l'art utilisée dans le mode de fonctionnement axisymétrique représenté à la figure 2b. A second mode of operation of the ATBM load, more and more used due to the greater precision of piloting and guiding the modern interceptor missiles carrying the load, is to obtain a mode of deployment of the bars axisymmetrically, the axis of deployment of the bars being the longitudinal axis XX 'of the load. FIG. 2a shows another example of ATBM load of the state of the art used in the axisymmetric operating mode shown in FIG. 2b.
La charge ATBM de la figure 2a comporte essentiellement un fagot 20 de barreaux 12 en tungstène et, dans un secteur central du fagot logé au cœur du fagot, un matériau énergétique 14 destiné à déployer les barreaux.  The ATBM load of FIG. 2a essentially comprises a bundle 20 of tungsten bars 12 and, in a central sector of the bundle housed in the middle of the bundle, an energetic material 14 intended to deploy the bars.
La charge ATBM de la figure 2a est destinée à être activée dans le mode dit axisymétrique. L'activation de la charge consiste à initier le matériau énergétique 14 du secteur central. Le rendu d'énergie du secteur central lors de l'activation du matériau énergétique 14 a pour effet le déploiement axisymétrique des barreaux 12 autour de l'axe XX' de la charge ATBM et, par conséquent, au moins une partie des barreaux 12 du fagot 10 se trouve dirigé vers la cible C à détruire. On cherche à supprimer le secteur énergétique central du fagot de barreaux tout en gardant un mode de fonctionnement axisymétrique de la charge. Le mode à effet dirigé est également conservé. A cet effet, l'invention propose une charge ATBM, d'axe longitudinal XX', destinée à détruire une cible C en mouvement, la charge comportant :  The ATBM load of FIG. 2a is intended to be activated in the so-called axisymmetric mode. The activation of the charge consists in initiating the energetic material 14 of the central sector. The energy rendering of the central sector during the activation of the energy material 14 has the effect of the axisymmetric deployment of the bars 12 around the axis XX 'of the ATBM load and, consequently, at least a portion of the bars 12 of the fagot 10 is directed towards the target C to be destroyed. It seeks to remove the central energy sector of the bundle of bars while maintaining an axisymmetric mode of operation of the load. The directed effect mode is also retained. For this purpose, the invention proposes an ATBM load, of longitudinal axis XX ', intended to destroy a target C in motion, the load comprising:
- un fagot de barreaux métalliques distribuées autour de l'axe longitudinal XX' de la charge,  a fagot of metal bars distributed around the longitudinal axis XX 'of the load,
- un ensemble de secteurs énergétiques entourant le fagot,  - a set of energy sectors surrounding the fagot,
- un dispositif d'activation des secteurs énergétiques,  an activation device for the energy sectors,
caractérisée en ce que les barreaux du fagot sont noyés dans un matériau élastique configuré pour absorber par compression dudit matériau élastique une partie de l'énergie générée par l'activation d'au moins un des secteurs énergétiques et restituer au mois partiellement au milieu environnant en se détendant la partie d'énergie absorbée lors de la compression et notamment sous forme d'énergie cinétique transmise aux barreaux par le matériau élastique.  characterized in that the bars of the bundle are embedded in an elastic material configured to absorb by compression of said elastic material part of the energy generated by the activation of at least one of the energetic sectors and partially restore to the surrounding environment in part the portion of energy absorbed during compression is relaxed, and in particular in the form of kinetic energy transmitted to the bars by the elastic material.
Avantageusement, dans la charge ATBM, le matériau élastique est choisi parmi les matériaux de type caoutchouc, polyuréthane, élastomère silicone. L'invention concerne aussi un procédé d'activation de charge ATBM selon l'invention, d'axe longitudinal XX', destinée à détruire une cible C en mouvement selon un axe ZZ', la charge comportant : Advantageously, in the ATBM load, the elastic material is chosen from rubber, polyurethane and silicone elastomer materials. The invention also relates to a method for activating the ATBM charge according to the invention, with a longitudinal axis XX ', intended to destroy a target C in motion along an axis ZZ', the charge comprising:
- un fagot de barreaux métalliques distribuées autour de l'axe longitudinal XX' de la charge, le fagot étant entouré d'un ensemble de secteurs énergétiques, les barreaux étant noyés dans un matériau élastique configuré pour absorber une partie de l'énergie générée par l'activation d'au moins un des secteurs énergétiques et restituer au mois partiellement au milieu environnant en se détendant la partie d'énergie absorbée lors de la compression et notamment sous forme d'énergie cinétique transmise aux barreaux par le matériau élastique.  a fagot of metal bars distributed around the longitudinal axis XX 'of the load, the bundle being surrounded by a set of energetic sectors, the bars being embedded in an elastic material configured to absorb a portion of the energy generated by the activation of at least one of the energetic sectors and partially restore to the surrounding environment by relaxing the portion of energy absorbed during the compression and in particular in the form of kinetic energy transmitted to the bars by the elastic material.
- un dispositif d'activation des secteurs énergétiques,  an activation device for the energy sectors,
caractérisé en ce qu'il comporte au moins les étapes suivantes :  characterized in that it comprises at least the following steps:
- détection de présence de la cible,  - presence detection of the target,
- activation d'au moins un des secteurs énergétiques.  activation of at least one of the energy sectors.
Dans une activation en mode à effet dirigé de la charge ATBM selon l'invention, un nombre de secteurs énergétiques inférieur au nombre de secteurs énergétiques entourant le fagot sont activés propulsant l'ensemble des barreaux vers la cible. In a directed mode activation of the ATBM charge according to the invention, a number of energetic sectors smaller than the number of energetic sectors surrounding the bundle are activated, propelling all the bars towards the target.
Dans une activation en mode axisymétrique, l'ensemble des secteurs énergétiques entourant le fagot sont activés de façon synchronisée pour fournir une énergie mécanique de compression du fagot restituée, au moins partiellement, sous forme d'énergie cinétique transmise aux barreaux par le matériau élastique. In an activation in axisymmetric mode, all energy sectors surrounding the bundle are activated in a synchronized manner to provide mechanical energy compression of the bundle restored, at least partially, in the form of kinetic energy transmitted to the bars by the elastic material.
Dans le mode axisymétrique, l'énergie générée par l'explosion simultanée de l'ensemble de secteurs énergétiques est absorbée au moins partiellement par le matériau élastique qui se trouve comprimé. L'énergie emmagasinée dans le matériau élastique est restituée en suite, lors de sa détente dispersant les barreaux du fagot axisymétriquement. In the axisymmetric mode, the energy generated by the simultaneous explosion of the set of energy sectors is absorbed at least partially by the elastic material which is compressed. The energy stored in the elastic material is then restored, during its expansion dispersing the bars of the bundle axisymétriquement.
L'invention prévoit un mode de fonctionnement de la charge ATBM différent des modes de l'état de l'art. Ce nouveau mode de fonctionnement permet d'obtenir ie mode de déploiement axisymétrique des barreaux sans la réaction d'un matériau énergétique dans un secteur central du fagot, mais en recourrant à l'action synchronisée de l'ensemble des secteurs énergétiques entourant le fagot. Cette configuration et procédé d'activation de la charge ATBM selon l'invention suppose que la définition de la charge et notamment du fagot soit adaptée, en noyant les barreaux dans une matrice d'absorption d'énergie faite d'un matériau élastique compressible, ainsi que le choix approprié du matériau énergétique (explosif détonant peu brisant, explosif déflagrant) The invention provides a mode of operation of the ATBM load different modes of the state of the art. This new mode of operation allows to obtain the mode of axisymmetric deployment of the bars without the reaction of an energetic material in a central sector of the bundle, but resorting to the synchronized action of all energy sectors surrounding the bundle. This configuration and method for activating the ATBM load according to the invention assumes that the definition of the load and in particular of the bundle is adapted by embedding the bars in an energy absorption matrix made of a compressible elastic material. as well as the appropriate choice of energy material (explosive detonating explosive, explosive explosive)

La figure 3a montre un exemple de charge ATBM selon l'invention, d'axe longitudinal XX', comportant un fagot 30 de barreaux 12 par exemple en tungstène noyés dans un matériau élastique 34 compressible. Le fagot 30 est entouré sur toute sa périphérie d'un ensemble de secteurs énergétiques E1 , E2,..Ei,... En. Le matériau élastique 34 peut être par exemple choisi parmi les matériaux de type caoutchouc, de type polyuréthane, par exemple un polyuréthane de désignation commerciale Ureflex ou Eladip, ou un élastomère silicone. Ces matériaux assurent leur mission grâce à leurs propriétés élastiques. Un dispositif d'activation, non représentée sur les figures, est configuré pour effectuer l'activation de la charge ATBM. FIG. 3a shows an example of an ATBM load according to the invention, of longitudinal axis XX ', comprising a bundle 30 of bars 12, for example made of tungsten, embedded in a compressible elastic material 34. The bundle 30 is surrounded on its entire periphery with a set of energetic sectors E1, E2, .. Ei, ... En. The elastic material 34 may for example be chosen from rubber-type materials, of the polyurethane type, for example a polyurethane of commercial designation Ureflex or Eladip, or a silicone elastomer. These materials ensure their mission thanks to their elastic properties. An activation device, not shown in the figures, is configured to perform the activation of the ATBM load.
La cible C est principalement un missile balistique se déplaçant à très grande vitesse selon l'axe ZZ'.  The target C is mainly a ballistic missile moving at a very high speed along the axis ZZ '.
Le dispositif d'activation de la charge ATBM comporte notamment des modules électroniques configurés pour la détection de la cible et l'activation de la charge ATBM. C'est l'intelligence électronique embarquée qui déterminera le mode de fonctionnement à activer en fonction de la position respective de la charge ATBM par rapport à sa cible, soit en mode dit à effet dirigé, soit en mode axisymétrique.  The device for activating the ATBM load notably comprises electronic modules configured for the detection of the target and the activation of the ATBM load. It is the on-board electronic intelligence that will determine the operating mode to be activated according to the respective position of the ATBM load relative to its target, either in the directed effect mode or in axisymmetric mode.
Par la suite, le procédé d'activation de la charge ATBM de la figure 3a est décrit en détail à l'aide des figues 3b et 3c dans un mode axisymétrique. Subsequently, the ATBM charge activation method of FIG. 3a is described in detail using FIGS. 3b and 3c in an axisymmetric mode.
Dans une première phase ne faisant partie du procédé d'activation de la charge, par exemple, une station au sol détecte un missile balistique, la charge ATBM est portée par son module auto-directeur vers le missile balistique à détruire (cible C).  In a first phase not part of the load activation process, for example, a ground station detects a ballistic missile, the ATBM load is carried by its self-steering module to the ballistic missile to be destroyed (target C).
Dans une deuxième phase, une fois la charge ATBM à proximité du missile balistique C un dispositif d'activation embarqué, par exemple une fusée de proximité, démarre le procédé d'activation de la charge ATBM qui consiste à initier de façon synchronisée l'explosion de l'ensemble des secteurs énergétiques E1 , E2,..Ei, ... En, autour du fagot 30.  In a second phase, once the ATBM load near the ballistic missile C an onboard activation device, for example a proximity fuse, starts the process of activating the ATBM charge which consists of synchronously initiating the explosion of all the energy sectors E1, E2, .. Ei, ... En, around the fagot 30.
L'explosion simultanée de l'ensemble des secteurs énergétiques entourant le fagot 30 produit, dans une première phase, la compression du matériau élastique 30 par des ondes acoustiques F de compression exercée sur la périphérie du fagot 30. Pendant cette première phase les barreaux se reprochent les uns des autres mais restent protégés par le matériau élastique dans lequel ils sont noyés.  The simultaneous explosion of all energy sectors surrounding the bundle 30 produces, in a first phase, the compression of the elastic material 30 by compression acoustic waves F exerted on the periphery of the bundle 30. During this first phase the bars are reproach each other but remain protected by the elastic material in which they are embedded.
Lors de la compression du fagot 30 une certaine quantité énergie mécanique est absorbée par le matériau élastique 34.  During the compression of the bundle 30 a certain amount of mechanical energy is absorbed by the elastic material 34.
Dans une deuxième phase, lorsque les ondes acoustiques de compression sur le fagot produites par l'explosion synchronisée de l'ensemble secteurs énergétiques disparaissent, le matériau élastique 34, en se détendant brusquement, restitue au mois partiellement au milieu environnant cette énergie absorbée lors de la compression et notamment sous forme d'énergie cinétique transmise aux barreaux par le matériau élastique. Les barreaux se déploient brusquement axisymétriquement en s'éloignant de l'axe longitudinal XX'. La charge ATBM, selon l'invention, peut être aussi activée dans un mode d'utilisation dit à effet dirigé dont le principe est représenté aux figures 1 a, 1 b et 1 c. In a second phase, when the acoustic compression waves on the bundle produced by the synchronized explosion of the energy sectors together disappear, the elastic material 34, while suddenly relaxing, partially restores to the surrounding medium this energy absorbed during compression and in particular in the form of kinetic energy transmitted to the bars by the elastic material. The bars unfold sharply axisymmetrically away from the longitudinal axis XX '. The ATBM charge, according to the invention, can also be activated in a so-called directed mode of use whose principle is represented in FIGS. 1a, 1b and 1c.
Dans ce mode dirigé, un certain nombre de secteurs énergétiques de la charge ATBM du côté de la cible C sont expulses ou éloignés du fagot 30 de manière à faciliter le déploiement des barreaux 12 dans la direction de la cible (voir figure 1 b). En suite, au moins un secteur énergétique de la charge opposé à la cible C est initié (secteur grisé E2 sur la figure 1 c) pour générer un déploiement des barreaux autour d'un axe MM' dirigé de la charge vers la cible (voir figure 1 c).  In this directed mode, a number of energy sectors of the ATBM load on the target C side are expelled or remote from the bundle 30 so as to facilitate the deployment of the bars 12 in the direction of the target (see Figure 1b). Next, at least one energy sector of the charge opposite to the target C is initiated (shaded area E2 in FIG. 1c) to generate a deployment of the bars around an axis MM 'directed from the load towards the target (see FIG. Figure 1 c).
Dans ce mode à effet dirigé de la charge selon l'invention, la présence de la matrice d'absorption (le matériau élastique compressible) est également bénéfique par la protection qu'elle assure sur les barreaux vis-à- vis de l'effet de la réaction du ou des secteurs énergétiques activés.  In this directed effect mode of the charge according to the invention, the presence of the absorption matrix (the compressible elastic material) is also beneficial by the protection it provides on the bars with respect to the effect the reaction of the activated energy sector or sectors.
La présence de la matrice d'absorption améliore le déploiement des barreaux.  The presence of the absorption matrix improves the deployment of the bars.
L'avantage de la charge ATBM selon l'invention est qu'elle n'embarque plus de secteur énergétique central 14, tout en assurant totalement son objectif de déploiement axisymétrique sur demande.  The advantage of the ATBM load according to the invention is that it no longer carries a central energy sector 14, while fully ensuring its objective of axisymmetric deployment on demand.
Un autre avantage de la charge ATMB selon l'invention est que, avec une même architecture de charge, les deux modes d'activation peuvent être utilisés, soit le mode à effet dirigé par l'activation d'un certain nombre limité de secteurs énergétiques, soit le mode axisymétrique, par l'activation de l'ensemble des secteurs énergétiques associé à la présence d'un matériau absorbeur/restituteur d'énergie.  Another advantage of the ATMB load according to the invention is that, with the same charge architecture, the two modes of activation can be used, namely the effect mode directed by the activation of a limited number of energy sectors. or the axisymmetric mode, by the activation of all the energy sectors associated with the presence of an absorber / energy recovery material.
