Abstract

Explosive appliance for the remote neutralisation of suspect devices. The invention relates to a propelled plate 1 making it possible to neutralise in large proportions devices which are assumed to be explosive. It consists of an escaping material 2 stiffened by means of a binder 3, propelled by an explosive charge 4 primed by a detonator 5, the assembly as a whole being contained in a housing 6. The user can position it by means of the double-faced adhesive tape 7, hang it by its hook 8 by means of a cord equipped with a magnet or place it on feet fastened by means of wing screws 9. The appliance of the invention is intended especially for rapid attacks, to attempt to neutralise suspect objects through obstacles, such as vehicle doors, boat bulkhead doors, partitions or walls of thin bricks, thereby reducing the risks of exposure of the user.

Description

Ce matériel préparé prêt à l'emploi, s'apparente à une munition destinée à neutraliser sans la faire exploser, un engin explosif improvisé. This ready-to-use prepared material is similar to ammunition intended to neutralize, without detonating it, an improvised explosive device.

Les matériels développés dans le cadre de la neutralisation des objets supposés explosifs en FRANCE, sont d'un emploi difficile, de part leur masse, leur volume, leur puissance explosive. Cette dernier donnant une énergie restante après travail supérieure à ce qui est acceptable en milieu urbain. The materials developed within the framework of the neutralization of supposedly explosive objects in FRANCE are difficult to use, due to their mass, their volume, their explosive power. The latter giving more energy after work than is acceptable in an urban environment.

Le principe utilisé, pour la construction de la plaque propulsée de neutralisation, limite les effets après travail, à des distances très rédui- tes. Exemple : un colis explosif placé dans un véhicule léger, sera neutralisé, sans que des projections, de matériaux ne sortent de ce véhicule. Les matériels utilisés à nos jours, peuvent projeteur des matériaux jusqu'à 400 mètres. Cette plaque propulsée, de neutralisation, peut-être utilisée, sur des engins télé, ou radio-commandés, ou manuellement. Elle peut-être parachutée en caisse, ou avec son utilisateur. The principle used, for the construction of the powered neutralization plate, limits the effects after work, at very short distances. Example: an explosive package placed in a light vehicle will be neutralized, without projections, of materials leaving this vehicle. The materials used today can project materials up to 400 meters. This propelled plate, of neutralization, can be used, on tele devices, or radio-controlled, or manually. It can be parachuted at the checkout, or with its user.

La plaque propulsée de neutralisation, représentée figure N 2, est constituée, des éléments suivants : un matériau fuyant, billes de plombs (1), maintenu rigide par un liant inerte, plâtre ou ciment rapide (2), propulsés par une nasse d'explosif (3). L'ensemble amorçé, par un dispositif soit élec- trique ou pyrotechnique (4), renforce par un roulai (5). Un boitier (6), renferme les éléments précités, et porte sur le dessus un crochet (9), sur les côtés des vis pour l'adaptation de pieds (10), La partie vant est ob turne par une plaque mince (7), sur laquelle, on dispose, deux bandes col- lantes double faoe (8). The powered neutralization plate, shown in Figure N 2, is made up of the following elements: a leaking material, pellets (1), held rigid by an inert binder, plaster or fast cement (2), powered by a basket of explosive (3). The whole primed, by a device either electric or pyrotechnic (4), reinforced by a roll (5). A box (6), encloses the aforementioned elements, and carries on the top a hook (9), on the sides of the screws for the adaptation of feet (10), the front part is ob turne by a thin plate (7) , on which there are two double faoe sticky strips (8).

Le boîtier (6), est réalisé pour le prototype en contre-plaqué de 10 me d'épaisseur, le matériau fuyant constitué, de billes de plombs dont le dia- mètre sera choisi en fonction des objectifs à traiter (1). Le liant inerte (2), sera mélangé avec la grenaille d'une façon homogène, puis coulé dans un moule. La matière explosive de propulsion (3), peut-être, de différentes nature, explosif nitré, explosif nitraté, de circonstance, commercial, voir de récupération, pour un stockage de longue durée, l'explosif en feuille souple FORMEX donne les meilleures garanties. Le relai (5), peut-être en
FORMEX, tétryl ou pentrite.L'amorçage sera pyrotechnique (détonateur, mèche lente étanche, d'une longueur supérieure à 50 cm, et d'un temps de combustion minimum de 60 seconden, initiée par un allumeur on un bout de feu), ou électrique (détonateur électrique instantané, ligne électrique consommable de 100 mètres ou 200 mètres, exploseur).The box (6) is made for the prototype in plywood 10 m thick, the leaking material consisting of lead pellets, the diameter of which will be chosen according to the objectives to be treated (1). The inert binder (2) will be mixed with the shot in a homogeneous manner, then poured into a mold. The explosive propellant (3), perhaps, of different nature, nitro explosive, nitrate explosive, occasional, commercial, see recovery, for long-term storage, the explosive in flexible sheet FORMEX gives the best guarantees . The relay (5), perhaps in
FORMEX, tetryl or pentrite. The ignition will be pyrotechnic (detonator, watertight slow wick, of a length greater than 50 cm, and a minimum combustion time of 60 seconds, initiated by an igniter on a piece of fire), or electric (instantaneous electric detonator, consumable electric line of 100 meters or 200 meters, exploder).

Il n'est pas obligstoire, d'incérer l'amorçage (4), à l'intérieur de ce matériel, la partie prenante pouvant faire son choix. Il lui est possible de le réaliser elle-mame. It is not compulsory to insert the priming (4) inside this material, the stakeholder being able to make their choice. It is possible for him to realize it herself.

La plaquette (7), obturant la partie avant est en contre-plaqué de 3 mm d'épaisseur, sur laquelle, deux bandes collantes double face (8), sont disposées. Le crochet de la partie supérieure du boîtier (9), est vissé, il sera de type ouvert. Il servira dans le cas d'utilisation d'un cordon pour la pose. tes 2 vis latérales (10), sont disposes, dans les côtés du boitier apres perçage d'un trou de diamètre adapté. Elles seront collées côté tête sur le boîtier. The plate (7), closing off the front part, is made of plywood 3 mm thick, on which two double-sided adhesive strips (8) are placed. The hook of the upper part of the housing (9) is screwed, it will be of the open type. It will be used when using a cord for installation. your 2 side screws (10) are arranged in the sides of the case after drilling a hole of suitable diameter. They will be stuck on the head side on the case.

L'utilisateur de la plaque propulsée de neutralisation placera celle-ci face à l'engin suspect, côté auto-collant, par l'un des trois modes de pose utilisables. Il amorcera le dispositif à l'aide d'un détonateur, qui commandera l'initiation de la charge explosive, qui propulsera la plaque en brisant le liant inerte. Chaque bille constituera un couteau destrouteur, pour l'objet suspect. The user of the powered neutralization plate will place it in front of the suspect vehicle, on the self-adhesive side, using one of the three usable installation methods. It will initiate the device using a detonator, which will control the initiation of the explosive charge, which will propel the plate by breaking the inert binder. Each ball will constitute a destroyer knife, for the suspect object.
