Abstract
Description
Les munitiions anti-personnelles généralement utilisées aujourd'hui qui contiennent un explosif dispersant de la grenaille métallique sont appelées couramment "grenades". Elles sont généralement constituées à partir d'enveloppes métalliques et d'explosifs coulés ou introduits dans le corps de la grenade sous forme de farine ou de semoule et comprimés plus ou moins fortement pour former un volume fermé contenant de l'explosif qui est initié par un système pyrotechnique lors de son utilisation. The anti-personal munitions generally used today which contain an explosive dispersing metallic shot are commonly called "grenades". They are generally formed from metallic envelopes and explosives poured or introduced into the body of the pomegranate in the form of flour or semolina and compressed more or less strongly to form a closed volume containing the explosive which is initiated by a pyrotechnic system during its use.
La figure 1 jointe à ce descriptif représente une des formes de réalisation de l'invention. Les figures 2 et 3 représentent l'explosif solide. Les figures 4 et 5 représentent de la grenaille (13) maintenue en place avec un matériau liant (12) de type résine ou plastique ou toute autre matière liante. La figure 6 représente la pièce d'interface permettant une fixation du bouchon allumeur initiant la grenade et permettant le passage d'un système de relais de détonation. La figure 7 représente une enveloppe thermorétractable qui, lorsqu'elle est soumise à un flux d'air chaud, vient se mettre sous la forme (6) de la figure 1. Figure 1 attached to this description represents one of the embodiments of the invention. Figures 2 and 3 show the solid explosive. Figures 4 and 5 show the shot (13) held in place with a binder material (12) of resin or plastic type or any other binder material. FIG. 6 represents the interface piece allowing a fixing of the igniter plug initiating the grenade and allowing the passage of a detonation relay system. FIG. 7 represents a heat-shrinkable envelope which, when subjected to a flow of hot air, comes to take the form (6) of FIG. 1.
La figure 8 représente une autre forme de l'invention ou l'enveloppe thermorétractable (6) est remplacée par un manchon thermorétractable (10) et un fond de maintien (ils. FIG. 8 represents another form of the invention where the heat-shrinkable envelope (6) is replaced by a heat-shrinkable sleeve (10) and a holding base (they.
La figure 9 représente une autre forme de l'invention avec de l'explosif solide (14) en un seul élément. Figure 9 shows another form of the invention with solid explosive (14) in a single element.
L'invention concerne la grenade et le procédé de réalisation de la grenade par assemblage d'explosifs solides, de grenaille maintenue par un liant, de pièces d'interfaces, et d'enveloppe thermorétractable de maintien de l'ensemble. The invention relates to the grenade and the method of producing the grenade by assembling solid explosives, shot maintained by a binder, interface parts, and heat-shrinkable envelope for holding the assembly.
La grenade, objet de la présente invention, est constituée par deux éléments (1) et (2) d'explosif solide laissant un passage (7) pour un relais de détonation et de deux pseudo-hémisphères (3) et (4) formés par de la grenaille (13) surmoulée avec un liant (12) de type résine, ou plastique, ou tout autre sorte de liant, d'une pièce d'interface (5) permettant la fixation à la grenade d'un élément de mise à feu de type bouchon allumeur, le tout étant fixé par une enveloppe thermorétractable (6). L'enveloppe (6) est mise en place avant sa rétractation et lors de l'opération de rétractation les éléments (1), (2), (3), (4), et (5) sont maintenus et se positionnent suivant la figure 1. The grenade, object of the present invention, consists of two elements (1) and (2) of solid explosive leaving a passage (7) for a detonation relay and two pseudo-hemispheres (3) and (4) formed by shot (13) overmolded with a binder (12) of resin type, or plastic, or any other kind of binder, an interface piece (5) allowing the fixing to the grenade of a setting element igniter plug type fire, the whole being fixed by a heat-shrinkable envelope (6). The envelope (6) is put in place before its retraction and during the retraction operation the elements (1), (2), (3), (4), and (5) are maintained and are positioned according to the figure 1.
Une lèvre (8) de l'élément (5) assure l'étanchéité. Un des perfectionnement de la présente invention est d'appliquer un produit d'étanchéité sur la lèvre (8) avant l'opération de thermorétraction. A lip (8) of the element (5) seals. One of the improvements of the present invention is to apply a sealant to the lip (8) before the heat-shrinking operation.
Une autre forme de la présente invention est de ne mettre qu'un manchon thermorétractable (10) et un fond de maitien et de protection (11) tels que présentés à la figure 8. Les étanchéités pouvant être assurées de façon indentique au montage de la figure 1. Another form of the present invention is to put only a heat-shrinkable sleeve (10) and a protective and protective bottom (11) as shown in FIG. 8. The seals which can be provided identically when mounting the figure 1.
Une des formes de l'invention est de remplacer la gaine thermorétractable (6) par un surmoulage en matière plastique. One of the forms of the invention is to replace the heat-shrinkable sheath (6) with a plastic overmolding.
Le comportement de la grenade lors de la mise à feu est le suivant
A l'instant de la mise à feu du système pyrotechnique d'initiation comprenant un relais d'amorçage de la détonation non représenté sur la figure 1, le système pyrotechnique d t initiation transmet la détonation à l'explosif constitué par (1) et (2) qui lui-même détone et projette la grenaille (13) contenue dans les pseudohémisphères (3) et (4) dans toutes les directions. Les constituants (5), (6) et le liant (12) des pseudo-hémisphères (3) et (4) étant des matières de type résine, plastique ou autres liants à caractéristiques mécaniques beaucoup plus faibles que les caractéristiques mécaniques de la grenaille (13) sont volatilisées sous l'effet de l'explosion et ne s'opposent pas à l'efficacité de la grenaille (13). The behavior of the grenade during firing is as follows
At the time of initiation of the initiation pyrotechnic system comprising a detonation initiation relay not shown in FIG. 1, the initiation pyrotechnic system transmits the detonation to the explosive consisting of (1) and ( 2) which itself detonates and projects the shot (13) contained in the pseudo-hemispheres (3) and (4) in all directions. The constituents (5), (6) and the binder (12) of the pseudo-hemispheres (3) and (4) being materials of the resin, plastic or other binder type with mechanical characteristics much weaker than the mechanical characteristics of shot (13) are volatilized under the effect of the explosion and do not oppose the effectiveness of the shot (13).
