Description

La présente invention concerne une charge militaire duale, pour missiles surface-air, destinée à l'attaque des cibles conventionnelles et également des missiles balistiques tactiques.The present invention relates to a dual military charge for missiles surface-air, intended for attacking conventional targets and also tactical ballistic missiles.

On sait que les charges militaires actuelles des missiles surface-air ne sont optimisées que pour un seul type d'objectif prédéterminé, alors que pour de nombreuses applications, ces charges explosives sont amenées à traiter plusieurs objectifs de types différents tels que notamment aéronefs et missiles. Il en résulte la nécessité de disposer de charges militaires différentes en fonction des objectifs à traiter étant donné qu'il est difficile de réaliser une charge assurant un compromis d'optimisation vis-à-vis des objectifs à traiter. Cette multiplicité de charges a bien entendu une incidence défavorable en particulier sur les coûts (de conception et de fabrication, de stockage, etc.) ainsi que sur la mise en oeuvre, ce qui pose des problèmes actuellement non résolus.We know that the current military charges for surface-to-air missiles are not optimized only for a single type of predetermined objective, whereas for many applications, these explosive charges are required to treat several objectives of different types such as in particular aircraft and missiles. This results in the need for military charges different depending on the objectives to be addressed since it is difficult to carry out a load ensuring an optimization compromise with respect to objectives to be addressed. This multiplicity of charges obviously has an impact unfavorable in particular on the costs (of design and manufacture, of storage, etc.) as well as implementation, which poses problems currently unresolved.

La présente invention s'est fixée pour objectif de résoudre ces problèmes en apportant une charge militaire unique, pour missiles surface-air conçue de façon à assurer la destruction, fonctionnelle ou structurale :

  • a) de cibles conventionnelles telles que notamment avions de combat, missiles tactiques subsoniques ou supersoniques ;
  • b) de missiles balistiques tactiques,
    • The present invention has set itself the objective of solving these problems by providing a single military charge, for surface-to-air missiles designed so as to ensure the destruction, functional or structural:
  • a) conventional targets such as in particular combat aircraft, subsonic or supersonic tactical missiles;
  • b) tactical ballistic missiles,

    • Cette double capacité de destruction est obtenue par le fait que la charge militaire selon l'invention possède deux modes de fonctionnement différents, chacun d'eux étant optimisés pour détruire l'un des deux types de cibles mentionnés ci-dessus. This double destruction capacity is obtained by the fact that the charge military according to the invention has two different operating modes, each of which is optimized to destroy one of two types of targets mentioned above.

    Cette invention a donc pour objet une charge militaire pour missile surface-air conçue pour la destruction fonctionnelle ou structurale, d'une part, de cibles conventionnelles et d'autre part, de missiles balistiques tactiques caractérisée en ce qu'elle comprend :

    • un chargement explosif principal constitué d'une pluralité de blocs élémentaires préformés ou non;
    • une enveloppe génératrice d'éclats prédéterminés disposée périphériquement audit chargement explosif ;
    • un système de mise à feu du chargement explosif, la détonation de ce dernier provoquant la fragmentation prédéterminée de l'enveloppe génératrice d'éclats ;
    • un système de cordeaux détonants de découpage prévus sur ladite enveloppe génératrice d'éclats et,
    • des colonnes d'explositfs de faible diamètre positionnées selon l'axe du chargement explosif de façon à réaliser une dislocation et une dispersion dudit chargement explosif et de l'enveloppe génératrice d'éclats découpée par ses cordeaux détonants.
    The subject of this invention is therefore a military charge for a surface-to-air missile designed for the functional or structural destruction, on the one hand, of conventional targets and, on the other hand, of tactical ballistic missiles, characterized in that it comprises:
    • a main explosive charge consisting of a plurality of elementary blocks, preformed or not;
    • an envelope generating predetermined fragments disposed peripherally to said explosive charge;
    • a system for igniting the explosive charge, the detonation of the latter causing the predetermined fragmentation of the shell generating fragments;
    • a system of detonating cutting cords provided on said casing generating splinters and,
    • columns of small diameter explosives positioned along the axis of the explosive charge so as to produce a dislocation and a dispersion of said explosive charge and of the shrapnel-generating envelope cut by its detonating cords.

    La conception et la disposition de la charge militaire sont telles que l'on obtient les deux modes de fonctionnement différents mentionnés ci-après :

  • - contre les cibles conventionnelles : un premier mode de fonctionnement obtenu par la détonation de l'explosif principal provoquant la fragmentation prédéterminée du générateur d'éclats permettant de générer dans une gerbe focalisée des éclats rapides ( 1 500 à 2 000 m/s.) et de masse faible (quelques grammes) ;
  • - contre des missiles balistiques tactiques : un second mode de fonctionnement générant des éclats lents (vitesse inférieure à ou de l'ordre de 100 m/s.) et de masses importantes (quelques dizaines à quelques centaines de grammes), d'une part par découpage du générateur d'éclats par ses cordeaux détonants et, d'autre part, par la dislocation du chargement explosif, ces éclats réactifs explosant à l'impact sur la cible sous l'effet du choc intense généré par la vitesse relative importante.
    • The design and layout of the military charge are such that the two different modes of operation mentioned below are obtained:
  • - against conventional targets: a first mode of operation obtained by the detonation of the main explosive causing the predetermined fragmentation of the burst generator making it possible to generate in a focused shower of fast bursts (1,500 to 2,000 m / s.) and of low mass (a few grams);
  • - against tactical ballistic missiles: a second operating mode generating slow bursts (speed less than or around 100 m / s.) and large masses (a few tens to a few hundred grams), on the one hand by cutting the burst generator with its detonating cords and, on the other hand, by the dislocation of the explosive charge, these reactive bursts exploding on impact on the target under the effect of the intense shock generated by the significant relative speed.

    • Selon un mode de réalisation de la présente invention, ledit chargement explosif principal est constitué par un empilage d'une pluralité de disques circulaires comportant chacun une pluralité de secteurs circulaires .According to an embodiment of the present invention, said loading main explosive consists of a stack of a plurality of discs circular, each comprising a plurality of circular sectors.

    D'autres caractéristiques et avantages de la présente invention ressortiront de la description faite ci-après en référence aux dessins annexés qui en illustrent un exemple de réalisation dépourvu de tout caractère limitatif.Other characteristics and advantages of the present invention will emerge of the description given below with reference to the accompanying drawings which illustrate an exemplary embodiment devoid of any limiting character.

    • La figure 2 représente en perspective, vue de dessus, la charge illustrée par la figure 1 ;
    • La figure 3 est une vue similaire à la figure 1 mais représentée avec arrachement partiel afin de montrer les constituants de ladite charge; - La figure 4 est une vue similaire à la figure 1 illustrant la formation d'éclats préfragmentés conformément au premier mode de fonctionnement de cette charge militaire et,
    • La figure 5 est une vue similaire à la figure 4 illustrant la formation d'éclats de masse importante conformément au second mode de fonctionnement de la charge.
    In the drawings:
    • Figure 1 is a perspective view of a military charge according to the present invention;
    • 2 shows in perspective, seen from above, the load illustrated in Figure 1;
    • Figure 3 is a view similar to Figure 1 but shown with partial cutaway to show the constituents of said load; FIG. 4 is a view similar to FIG. 1 illustrating the formation of pre-fragmented flakes in accordance with the first mode of operation of this military charge and,
    • Figure 5 is a view similar to Figure 4 illustrating the formation of large mass splinters in accordance with the second mode of operation of the load.

    En se référant aux dessins, on voit que, dans cet exemple de réalisation dépourvu de tout caractère limitatif, la charge militaire objet de la présente invention comprend un chargement explosif qui est constitué par un empilage d'une pluralité de disques circulaires 10, comportant chacun une pluralité de secteurs circulaires tels que 10a, 10b (figure 2). Cette charge peut être mise à feu par un relais renforçateur 12 lui-même actionné par un cordeau détonant de transmission 14. Ce système comporte en outre un dispositif de sécurité d'armement, non représenté sur le dessin et qui comporte deux sorties pyrotechniques, le cordeau détonant de transmission 14 étant relié à l'une de ces sorties. Referring to the drawings, it can be seen that, in this exemplary embodiment devoid of any limiting nature, the military charge which is the subject of this invention includes an explosive charge which consists of a stacking of a plurality of circular discs 10, each comprising a plurality of circular sectors such as 10a, 10b (Figure 2). This charge can be ignited by a booster relay 12 itself actuated by a detonating transmission cord 14. This system further includes a armament security device, not shown in the drawing and which has two pyrotechnic outputs, the detonating transmission cord 14 being connected to one of these outputs.

    De façon classique, le chargement explosif est enfermé dans une enveloppe génératrice d'éclats désignée dans son ensemble par la référence 16 et qui dans cet exemple de réalisation est constituée d'une pluralité de couronnes circulaires telles que 16a, 16b (figure 1). Cette enveloppe, de façon connue, comporte une fragmentation prédéterminée de manière à pouvoir générer des éclats de masse faible et de vitesse importante, lors de la mise à feu du chargement explosif 10 ainsi qu'on le décrira ci-après. Selon la présente invention, l'enveloppe génératrice d'éclats 16 peut être disposée sur ou sous la structure de la charge.Conventionally, the explosive charge is enclosed in an envelope burst generator designated as a whole by the reference 16 and which in this exemplary embodiment consists of a plurality of crowns circulars such as 16a, 16b (Figure 1). This envelope, in a known manner, has a predetermined fragmentation so that it can generate bursts of low mass and high speed, when igniting the explosive charge 10 as will be described below. According to this invention, the fragment-generating envelope 16 can be arranged on or under the load structure.

    Selon l'invention, on prévoit des cordeaux détonants de découpage tels que 18 qui sont positionnés sur la surface extérieure ou intérieure de l'enveloppe génératrice d'éclats 16 ainsi qu'on le voit clairement sur les figures qui illustrent l'exemple de réalisation non limitatif selon lequel ces cordeaux de découpage 18 sont positionnés sur la surface extérieure de l'enveloppe 16. La fonction de ces cordeaux détonants est de provoquer une dislocation de l'enveloppe génératrice d'éclats afin de générer des éclats de masse importante et de faible vitesse, ainsi qu'on le décrira ci-après.According to the invention, detonating cutting cords such as 18 which are positioned on the outer or inner surface of the envelope splinter generator 16 as can be clearly seen in the figures which illustrate the nonlimiting exemplary embodiment according to which these strings of cutting 18 are positioned on the outer surface of the casing 16. The function of these detonating cords is to cause a dislocation of the shrapnel-generating envelope in order to generate mass shrapnel important and low speed, as will be described below.

    La charge comporte en outre des colonnes d'explosif de faible diamètre telles que 20a et 20b qui dans cet exemple de réalisation sont disposées selon l'axe du chargement explosif, ces colonnes d'explosif, qui sont connectées à l'autre sortie pyrotechnique du dispositif de sécurité d'armement mentionné ci-dessus, étant conçues afin d'assurer une dislocation puis une dispersion du chargement explosif 10, sans provoquer la mise à feu de celui-ci. Afin d'éviter cette mise à feu par le relais 12, les colonnes d'explosifs 20a et 20b sont isolées de ce dernier, par exemple, en les noyant dans un matériau amortisseur de choc 22 constitué par exemple d'une résine chargée en micro sphères de verre ou de tout autre matériau s'opposant à la mise à feu du relais 12 lors de l'initiation des colonnes d'explosifs 20a et 20b qui projettent à faible vitesse les éclats inertes et réactifs. The charge also comprises columns of small diameter explosives such as 20a and 20b which in this embodiment are arranged along the axis of the explosive charge, these explosive columns, which are connected to the other pyrotechnic output of the safety device mentioned above, being designed to ensure dislocation and then dispersal of the explosive charge 10, without causing the firing of it. In order to avoid this ignition by relay 12, the explosives columns 20a and 20b are isolated from the latter, for example, by embedding them in a shock absorbing material 22 constituted for example a resin loaded with microspheres of glass or any other material opposing the firing of relay 12 during the initiation of the columns explosives 20a and 20b which project inert shrapnel at low speed and reactive.

    Le fonctionnement de cette charge militaire s'opère de la façon suivante :The functioning of this military charge operates as follows:

    1°) Attaque de cibles conventionnelles telles que notamment : avions de combat, missiles tactiques subsoniques ou supersoniques.1 °) Attack of conventional targets such as in particular: combat, tactical subsonic or supersonic missiles.

    Dans ce premier mode de fonctionnement, la mise à feu du relais 12 provoque l'explosion du chargement explosif 10 de manière que l'enveloppe génératrice d'éclats 16 génère une gerbe focalisée d'éclats tels que 24 (figure 4), de vitesse importante, c'est-à-dire de l'ordre de 1 500 à 2 000 m./s. et de masse faible, de l'ordre de quelques grammes.In this first operating mode, the firing of relay 12 causes the explosive charge 10 to explode so that the envelope burst generator 16 generates a focused burst of bursts such as 24 (Figure 4), of high speed, that is to say of the order of 1,500 to 2,000 m./s. and of low mass, of the order of a few grams.

    2°) Attaque de missiles balistiques tactiques.2 °) Attack of tactical ballistic missiles.

    Selon ce second mode de fonctionnement, le relais 12 n'est pas actionné, l'enveloppe génératrice d'éclats 16 est découpée par ses cordeaux détonants tels que 18 de manière à générer, des éclats inertes tels que 26 représentés par la zone hachurée sur la figure 5, ces éclats étant de masse importante, c'est-à-dire de quelques dizaines à quelques centaines de grammes et de vitesse inférieure à 100 m./s.. Par ailleurs, on génère des éclats réactifs qui résultent de la dislocation du chargement explosif 10 provoquée par la mise à feu des colonnes d'explosifs 20a et 20b qui mettent en vitesse des éclats inertes ou réactifs.According to this second operating mode, the relay 12 is not actuated, the casing generating fragments 16 is cut by its cords detonants such as 18 so as to generate inert shrapnel such as 26 represented by the hatched area in FIG. 5, these flakes being of mass significant, i.e. from a few dozen to a few hundred grams and speed less than 100 m./s .. In addition, we generate reactive flashes that result from the dislocation of the explosive charge 10 caused by the firing of the explosive columns 20a and 20b which set in speed of inert or reactive flashes.

    On réalise ainsi une dispersion du chargement explosif en ses éléments constitutifs 10a et 10b. Ainsi, selon ce second mode de fonctionnement, la charge militaire génère des éclats inertes 26 et, des éclats réactifs résultant de la dislocation du chargement 10, lesquels explosent à l'impact sur la cible, grâce à leur grande vitesse relative. La cible est donc détruite d'une part, par l'action de cette explosion et d'autre part, par celle des éclats inertes tels que 26.This produces a dispersion of the explosive charge into its elements components 10a and 10b. Thus, according to this second mode of operation, the military charge generates inert flash 26 and reactive flash resulting of the dislocation of the load 10, which explode on impact on the target, thanks to their high relative speed. The target is therefore destroyed by firstly, by the action of this explosion and secondly, by that of the shards inert such as 26.

    On comprend de la lecture faite ci-dessus que la présente invention apporte une solution simple et efficace au problème de la conception d'une charge militaire duale permettant à la fois l'attaque de cibles conventionnelles et de missiles balistiques tactiques.It is understood from the reading made above that the present invention provides a simple and effective solution to the problem of load design dual military allowing both the attack on conventional targets and tactical ballistic missiles.

    Parmi les avantages apportés par l'invention, on peut citer notamment les suivants :

    • la génération d'éclats réactifs permet de doubler la masse des éclats projetés permettant d'obtenir une densité d'éclats plus élevée et plus homogène dans la gerbe développée autour du missile surface-air ;
    • le second mode de fonctionnement permet également d'assurer la fonction neutralisation du missile sol-air en cas de défaillance de son guidage. En effet, les cordeaux détonants tels que 18 découpent la structure de la charge, c'est-à-dire la structure du missile, sans initier l'explosif 10 du chargement. Ainsi, on obtient les modes de fonctionnement suivants :
    Among the advantages provided by the invention, the following may be mentioned in particular:
    • the generation of reactive shards makes it possible to double the mass of the projected shards making it possible to obtain a higher and more homogeneous shard density in the spray developed around the surface-air missile;
    • the second operating mode also makes it possible to ensure the neutralization function of the surface-to-air missile in the event of a failure of its guidance. Indeed, the detonating cords such as 18 cut the structure of the charge, that is to say the structure of the missile, without initiating the explosive 10 of the charge. Thus, the following operating modes are obtained:

    Premier mode de fonctionnement : attaque des cibles conventionnelles ou autodestruction du missile ;First mode of operation: attack on conventional targets or missile self-destruction;

    Second mode de fonctionnement : attaque des missiles balistiques tactiques ou neutralisation du missile.Second operating mode: attack of tactical ballistic missiles or neutralization of the missile.

    Il demeure bien entendu que la présente invention n'est pas limitée aux modes de mise en oeuvre et aux exemples de réalisation décrits et/ou mentionnés ci-dessus mais qu'elle en englobe toutes les variantesIt remains to be understood that the present invention is not limited to modes of implementation and the embodiments described and / or mentioned above but that it encompasses all variants
