Description

Le secteur technique de la présente invention est celui des dispositifs de neutralisation d'engins explosifs plus particulièrement appliqués aux engins explosifs improvisés ou colis piégés placés dans une capacité résistante.The technical sector of the present invention is that of devices for neutralizing explosive devices more particularly applied to improvised explosive devices or trapped packages placed in a resistant capacity.

Dans ce domaine, plusieurs réalisations se rapportant à des canons à eau ont déjà été proposées.In this area, several embodiments relating to water cannons have already been proposed.

De tels canons comportent essentiellement un tube métallique de forme généralement cylindrique contenant l'eau à projeter, fermé à l'une de ses extrémités pourvue d'un système de mise à feu, l'autre extrémité étant munie d'un convergent axial. De tels canons à eau font l'objet, par exemple, des brevets EP 178.039 et EP 198.728.Such cannons essentially comprise a metal tube of generally cylindrical shape containing the water to be sprayed, closed at one of its ends provided with a firing system, the other end being provided with an axial convergent. Such water cannons are the subject, for example, of patents EP 178,039 and EP 198,728.

Le brevet FR 2.661.490 décrit un canon à eau comportant notamment différentes rallonges venant se fixer entre l'extrémité du tube et le convergent afin de moduler la longueur du tube et la quantité d'eau projeté en fonction de la vitesse de sortie souhaitée.Patent FR 2,661,490 describes a water cannon comprising in particular various extensions coming to be fixed between the end of the tube and the convergent in order to modulate the length of the tube and the quantity of water projected according to the desired exit speed.

Tous ces canons à eau fonctionnent par déflagration d'une certaine quantité de poudre placée dans une cartouche entraînant la projection d'un jet d'eau à une vitesse de l'ordre de quelques centaines de mètres par seconde.All these water cannons operate by deflagration of a certain quantity of powder placed in a cartridge causing the projection of a jet of water at a speed of the order of a few hundred meters per second.

Bien qu'étant bien adapté à la neutralisation et à la destruction d'engins explosifs ou colis piégés placés dans une capacité à structure faible (carton) ou semi-rigide (mallette), ces canons à eau restent d'efficacité douteuse voire inexistante face à des structures plus résistantes du type coffre de voiture, armoire forte par exemple.Although they are well suited to the neutralization and destruction of explosive devices or trapped packages placed in a weak structure capacity (cardboard) or semi-rigid (case), these water cannons remain of questionable or even nonexistent effectiveness. to more resistant structures such as a car trunk, strong cabinet for example.

De plus, l'utilisation de ce type de canons à eau pose certaines difficultés notamment lors d'interventions manuelles dans des espaces exigus ou encombrés.In addition, the use of this type of water cannon poses certain difficulties, particularly during manual interventions in confined or congested spaces.

Le but de la présente invention est de remédier aux inconvénients rappelés ci-dessus en proposant un dispositif de neutralisation d'engins explosifs notamment d'engins explosifs improvisés placés dans une capacité à structure résistante, capable de générer un jet d'eau suffisamment puissant pour perforer la paroi rigide de la capacité et détruire par suite l'engin explosif contenu dans celle-ci, avant que celui-ci n'ait pu fonctionner.The object of the present invention is to remedy the drawbacks mentioned above by proposing a device for neutralizing explosive devices, in particular improvised explosive devices placed in a capacity with a resistant structure, capable of generating a jet of water sufficiently powerful to perforate the rigid wall of the container and consequently destroy the explosive device contained therein, before it has been able to function.

On notera que le niveau de l'énergie résiduel de l'eau projetée est tel qu'il n'engendre pas l'initiation des explosifs secondaires classiques utilisés dans la confection des engins explosifs improvisés.Note that the residual energy level of the projected water is such that it does not cause the initiation of conventional secondary explosives used in the manufacture of improvised explosive devices.

La présente invention a également pour but de faciliter les interventions de neutralisations et destructions d'engins explosifs ou colis piégés se trouvant dans des espaces exigus difficiles d'accès pour des systèmes d'intervention existants du type canons à eau par exemple.The present invention also aims to facilitate interventions to neutralize and destroy explosive devices or booby traps located in tight spaces difficult to access for existing intervention systems of the water cannon type, for example.

Un autre but de l'invention est de positionner le dispositif de neutralisation à proximité de l'engin explosif avec un maximum de sécurité pour l'opérateur, par l'intermédiaire d'un moyen d'acheminement autonome commandé à distance.Another object of the invention is to position the neutralization device near the explosive device with maximum safety for the operator, by means of an autonomous routing means controlled remotely.

Pour ce faire, l'invention a pour objet un dispositif de neutralisation d'engins explosifs notamment d'engins explosifs improvisés à enveloppe résistante, du type comportant des moyens d'amorçage d'une charge explosive projetant un liquide vers l'engin, dispositif caractérisé en ce qu'il est constitué d'un corps compact présentant une ouverture fermée par un couvercle, le corps réalisé en un matériau synthétique rigide contient la charge explosive et un récipient pour le liquide, le récipient étant placé au niveau de l'ouverture du corps et au contact de la charge.To do this, the subject of the invention is a device for neutralizing explosive devices, in particular improvised explosive devices with a resistant envelope, of the type comprising means for initiating an explosive charge projecting a liquid towards the device, device characterized in that it consists of a compact body having an opening closed by a cover, the body made of a rigid synthetic material contains the explosive charge and a container for the liquid, the container being placed at the level of the opening of the body and in contact with the load.

De préférence, le corps du dispositif est réalisé en un matériau thermoplastique du type polystyrène expansé dur.Preferably, the body of the device is made of a thermoplastic material of the hard expanded polystyrene type.

De préférence, la charge explosive est constituée par une feuille d'explosif du type plastique à base de penthrite recouvrant au moins partiellement la paroi externe du récipient.Preferably, the explosive charge consists of an explosive sheet of the plastic type based on penthrite covering at least partially the external wall of the container.

Selon un premier mode de réalisation, le récipient réalisé en matière plastique présente une section de forme semi-circulaire et est fermé par le couvercle de surface plane et un joint d'étanchéité en silicone.According to a first embodiment, the container made of plastic material has a semicircular section and is closed by the flat surface cover and a silicone seal.

Selon un second mode de réalisation le récipient en matière plastique présentant une paroi latérale cylindrique est fermé au niveau de l'ouverture du corps par le couvercle de forme conique et un joint d'étanchéité en silicone.According to a second embodiment, the plastic container having a cylindrical side wall is closed at the opening of the body by the conical cover and a silicone seal.

De préférence, les moyens d'amorçage comprennent un relais pyrotechnique placé au contact de la charge explosive et un détonateur électrique positionné dans un logement pratiqué dans le corps du dispositif.Preferably, the ignition means comprise a pyrotechnic relay placed in contact with the explosive charge and an electric detonator positioned in a housing formed in the body of the device.

Selon une variante d'utilisation, le dispositif comporte un insert noyé dans le corps, permettant la solidarisation du dispositif avec un support du type trépied.According to a variant of use, the device comprises an insert embedded in the body, allowing the device to be secured with a support of the tripod type.

Selon une autre variante d'utilisation, le dispositif comporte au moins un insert renfermant un axe permettant de fixer le corps sur un étrier par au moins une vis, le corps du dispositif étant libre en rotation par rapport à l'étrier réalisé en polycarbonate comportant un trou débouchant servant à fixer le dispositif sur l'extrémité du bras télescopique d'un moyen d'acheminement autonome commandé à distance.According to another variant of use, the device comprises at least one insert enclosing an axis making it possible to fix the body to a stirrup by at least one screw, the body of the device being free to rotate relative to the stirrup made of polycarbonate comprising a through hole used to fix the device on the end of the telescopic arm of a remote controlled autonomous conveying means.

Suivant l'importance ou la forme de l'objet à traiter, il sera également possible d'associer par juxtaposition ou superposition à l'aide de barrettes de liaison, au moins deux dispositifs de neutralisation d'engins explosifs selon l'un quelconque des modes de réalisation et/ou d'utilisation énoncés ci-dessus.Depending on the size or shape of the object to be treated, it will also be possible to combine by juxtaposition or superposition with the aid of connecting bars, at least two devices for neutralizing explosive devices according to any one of the embodiments and / or use set out above.

Selon une variante d'utilisation immergée, le récipient est ouvert vers l'avant par suppression du couvercle, le récipient étant rempli au moment de l'intervention, par le liquide ambiant.According to a variant of immersed use, the container is opened towards the front by removing the cover, the container being filled at the time of the intervention, with the ambient liquid.

Ce dispositif très fiable présente l'avantage d'être très compact, ce qui facilite les interventions manuelles ou à distance dans des espaces exigus.This very reliable device has the advantage of being very compact, which facilitates manual or remote interventions in tight spaces.

Un autre avantage réside dans la constitution du corps en polystyrène expansé et de l'étrier en polycarbonate ne générant pas d'éclat lors de la mise à feu du dispositif.Another advantage lies in the constitution of the expanded polystyrene body and the polycarbonate stirrup which does not generate a shine when the device is ignited.

Un autre avantage est que ce dispositif présente une très grande efficacité face à des capacités épaisses et résistantes, grâce à son mode de fonctionnement par détonation entraînant la propagation d'une onde de choc à une vitesse de l'ordre de 7 à 8000 m/s générant un jet d'eau projeté sur l'objectif à une vitesse de l'ordre du millier de mètres par seconde. De plus, la forme du jet d'eau est optimisée par la forme du couvercle du récipient.Another advantage is that this device has a very high efficiency in the face of thick and resistant capacities, thanks to its mode of operation by detonation causing the propagation of a shock wave at a speed of the order of 7 to 8000 m / s generating a jet of water projected onto the objective at a speed of the order of a thousand meters per second. In addition, the shape of the water jet is optimized by the shape of the container lid.

D'autres caractéristiques et avantages de l'invention apparaîtront dans la description détaillée, non limitative, de deux modes de réalisation de l'invention.Other characteristics and advantages of the invention will appear in the detailed, non-limiting description, of two embodiments of the invention.

Cette description sera faite en regard des dessins annexés parmi lesquels :

  • - la figure 1 représente une vue arrière du dispositif de neutralisation d'engins explosifs selon l'invention,
  • - la figure 2 représente une vue en coupe longitudinale selon A de la figure 1, du dispositif de neutralisation conçu selon le premier mode de réalisation,

  • - la figure 4 représente une vue de côté de l'association par superposition de deux dispositifs de neutralisation fixés au bras télescopique d'un moyen d'acheminement autonome commandé à distance.
This description will be made with reference to the appended drawings in which:
  • FIG. 1 represents a rear view of the device for neutralizing explosive devices according to the invention,
  • FIG. 2 represents a view in longitudinal section along A of FIG. 1, of the neutralization device designed according to the first embodiment,

  • - Figure 4 shows a side view of the association by superposition of two neutralization devices attached to the telescopic arm of an autonomous routing means controlled remotely.

En référence aux figures 1 et 2, on voit un dispositif de neutralisation d'engins explosifs selon l'invention constitué notamment d'un corps 3 compact réalisé en polystyrène expansé dur se présentant sous la forme d'un cylindre plein de faible longueur présentant une ouverture 4. La section externe du corps n'est pas limitée à la forme octogonale représentée par la figure 1, elle peut être de forme circulaire, polygonale régulière ou quelconque. L'ouverture 4 est fermée par un couvercle 6, de surface plane et de faible épaisseur réalisé en matière plastique, qui constitue la face avant du dispositif.With reference to FIGS. 1 and 2, an explosive device neutralization device according to the invention is seen, consisting in particular of a compact body 3 made of hard expanded polystyrene in the form of a short short solid cylinder having a opening 4. The external section of the body is not limited to the octagonal shape shown in Figure 1, it can be circular, regular polygonal or any shape. The opening 4 is closed by a cover 6, of flat surface and of small thickness made of plastic, which constitutes the front face of the device.

Dans l'ouverture 4 du corps sont logés :

  • - un récipient 5 réalisé en matière plastique fermé par le couvercle 6 et un joint d'étanchéité 7 en silicone, le récipient présentant une section de forme semi-circulaire étant rempli en totalité par de l'eau 2 éventuellement additionnée d'un produit antigel,
  • - une charge explosive 1 constituée par une feuille d'explosif plastique à base de penthrite recouvrant en totalité la surface externe de la paroi du récipient.
In the opening 4 of the body are housed:
  • a container 5 made of plastic material closed by the cover 6 and a silicone gasket 7, the container having a semi-circular cross section being completely filled with water 2 possibly added with an antifreeze product ,
  • - An explosive charge 1 consisting of a plastic explosive sheet based on penthrite completely covering the external surface of the wall of the container.

Le corps 3 du dispositif présente un logement 11 axial de forme cylindrique dans lequel est positionné un détonateur électrique 17 associé à un relais pyrotechnique 10 cylindrique placé au contact de la charge explosive 1.The body 3 of the device has an axial housing 11 of cylindrical shape in which is positioned an electric detonator 17 associated with a cylindrical pyrotechnic relay 10 placed in contact with the explosive charge 1.

Un insert 12 noyé dans le corps au niveau du centre de l'une de ses surfaces latérales permet de fixer le dispositif sur un trépied (non représenté) de type connu. Lors d'une intervention manuelle, ce trépied robuste, stable et bénéficiant d'une grande plage de réglage en hauteur assure un bon positionnement du dispositif par rapport à l'objectif à neutraliser.An insert 12 embedded in the body at the center of one of its lateral surfaces makes it possible to fix the device on a tripod (not shown) of known type. During a manual intervention, this robust, stable tripod with a large height adjustment range ensures good positioning of the device relative to the objective to be neutralized.

Un autre insert 13, placé radialementdans la partie supérieure du corps et symétriquement par rapport aux faces avant et arrière de celui-ci, renferme un axe 18 aux extrémités duquel est maintenu libre en rotation par deux vis en nylon 15 un étrier 14 en fore de U réalisé en polycarbonate. Cet étrier 14 comporte au milieu de sa partie transversale un trou 16 dans lequel est fixé par tout moyen connu, vis par exemple, l'extrémité 19 du bras télescopique d'un moyen d'acheminement autonome commandé à distance (non représenté) du type robot télécommandé de petite taille.Another insert 13, placed radially in the upper part of the body and symmetrically with respect to the front and rear faces thereof, contains an axis 18 at the ends of which is kept free to rotate by two nylon screws 15 a stirrup 14 made of U made of polycarbonate. This stirrup 14 has in the middle of its transverse part a hole 16 in which is fixed by any known means, for example screw, the end 19 of the telescopic arm of an autonomous remote controlled routing means (not shown) of the type small remote-controlled robot.

Lors d'intervention à distance, le placement original de l'axe de maintien 18 et de l'étrier 14 par rapport au centre de gravité du corps, permet de conserver le dispositif en position horizontale face avant dirigée vers l'objectif, pendant la durée du transport par le robot et celle de la mise à feu du dispositif.During remote intervention, the original placement of the retaining pin 18 and the stirrup 14 relative to the center of gravity of the body, makes it possible to keep the device in a horizontal position, front face directed towards the objective, during the duration of transport by the robot and that of ignition of the device.

La figure 3 est une variante de réalisation du dispositif précédent selon un autre caractéristique de l'invention.Figure 3 is an alternative embodiment of the previous device according to another characteristic of the invention.

Le dispositif représenté ici comporte un corps 3 de forme sensiblement identique à celui décrit précédemment, il est également réalisé en polystyrène expansé dur. Toutefois les dimensions du dispositif pourront être différentes, sans sortir du cadre de la présente invention. On retrouve également des moyens d'amorçage et une charge explosive 1 du même type, ainsi qu'un étrier 14 de liaison avec le bras d'un robot, positionné de la même manière que dans le mode de réalisation précédent. Le relai pyrotechnique pourra éventuellement être supprimé grà- ce à l'emploi d'une charge explosive de composition différente. La principale originalité du second mode de réalisation réside essentiellement dans la forme du récipient 8 et surtout dans celle du couvercle 9.The device shown here comprises a body 3 of shape substantially identical to that described above, it is also made of hard expanded polystyrene. However, the dimensions of the device may be different, without departing from the scope of the present invention. There are also priming means and an explosive charge 1 of the same type, as well as a stirrup 14 for connection with the arm of a robot, positioned in the same manner as in the previous embodiment. The pyrotechnic relay may possibly be eliminated by the use of an explosive charge of different composition. The main originality of the second embodiment lies essentially in the shape of the container 8 and especially in that of the cover 9.

Le récipient 8 réalisé en matière plastique rigide présente une forme sensiblement cylindrique, fermé à l'arrière par un fond et à l'avant par un couvercle 9 de forme conique et de faible épaisseur réalisé en matière plastique associé à un joint d'étanchéité 7 en silicone placé entre le couvercle et le récipient.The container 8 made of rigid plastic material has a substantially cylindrical shape, closed at the rear by a bottom and at the front by a cover 9 of conical shape and of small thickness made of plastic material associated with a seal 7 silicone placed between the lid and the container.

La feuille d'explosif 1 recouvre en totalité les parois externes du récipient 8, fond y compris.The explosive sheet 1 completely covers the external walls of the container 8, including the bottom.

De la même manière cette variante peut faire l'objet d'une utilisation manuelle sur trépied ou à distance par robot télécommandé.In the same way this variant can be used manually on a tripod or remotely by remote-controlled robot.

La figure 4 est une association particulière par superposition de deux dispositifs de neutralisation réalisés suivant l'une quelconque des deux variantes décrites ci-dessus.FIG. 4 is a particular association by superposition of two neutralization devices produced according to any one of the two variants described above.

L'association de deux ou plusieurs dispositifs peut être réalisée au moyen de deux barrettes de liaison 20. Chaque barrette en polycarbonate percée de plusieurs trous est fixée grâce à des vis à bois sur le corps 3 de chaque dispositif.The association of two or more devices can be achieved by means of two connecting bars 20. Each polycarbonate bar pierced with several holes is fixed by means of wood screws to the body 3 of each device.

Le dispositif supérieur peut être relié à l'extrémité 19 du bras télescopique du robot par l'intermédiaire de l'étrier 14 à l'occasion d'une intervention à distance.The upper device can be connected to the end 19 of the telescopic arm of the robot via the stirrup 14 during a remote intervention.

Toute association différente, par juxtaposition par exemple reste couverte par la présente invention.Any different association, for example by juxtaposition, remains covered by the present invention.

Le fonctionnement du dispositif est le suivant.The operation of the device is as follows.

Suivant le type d'objectif à neutraliser et à détruire, l'utilisateur choisira le dispositif le plus approprié réalisé suivant l'une ou l'autre des variations décrites précédemment et éventuellement l'association de deux ou plusieurs dispositifs si nécessaire.Depending on the type of objective to neutralize and destroy, the user will choose the most appropriate device made according to one or other of the variations described above and possibly the combination of two or more devices if necessary.

Suivant l'exiguïté de l'espace d'intervention, il sera également possible d'opté soit pur une intervention manuelle sur trépied, soit à distance par l'intermédiaire d'un robot télécommandé acheminant le dispositif à proximité de la capacité susceptible de contenir une charge explosive ou un colis piégé par exemple.Depending on the smallness of the intervention space, it will also be possible to opt either for manual intervention on a tripod, or remotely via a remote-controlled robot transporting the device near the capacity likely to contain an explosive charge or a booby-trapped package, for example.

La face avant du dispositif est placée à environ 2 à 3 centimètres de la paroi externe de la capacité. Le détonateur électrique 17 est relié par un câble électrique de longueur suffisante à une source de courant de type connu, exploseur, batterie de voiture par exemple.The front face of the device is placed approximately 2 to 3 centimeters from the external wall of the container. The electric detonator 17 is connected by an electric cable of sufficient length to a current source of known type, exploder, car battery for example.

A la mise à feu, le détonateur 17 initie la charge explosive 1 éventuellement par l'intermédiaire du relais pyrotechnique 10, formant une onde de détonation propulsant et focalisant l'eau 2 contenue dans le récipient 5 ou 8.When ignited, the detonator 17 initiates the explosive charge 1 possibly via the pyrotechnic relay 10, forming a detonation wave propelling and focusing the water 2 contained in the container 5 or 8.

L'énergie acquise permet au liquide de former un jet capable de traverser la paroi de l'objectif et de neutraliser son contenu.The energy acquired allows the liquid to form a jet capable of passing through the wall of the objective and neutralizing its content.

Le risque de projection des morceaux employés dans la construction du dispositif devient nul à 25 mètres de celui-ci.The risk of projection of the pieces used in the construction of the device becomes zero at 25 meters from it.

Lors d'interventions sous l'eau pour neutraliser un engin explosif placé sur la coque d'un navire par exemple, on utilise un dispositif simplifié (non représenté) comportant notamment le récipient 5 ou 8 non fermé par le couvercle 6 ou 9. De préférence, le récipient présente une section de forme semi-circulaire 5.During interventions underwater to neutralize an explosive device placed on the hull of a ship for example, a simplified device is used (not shown) comprising in particular the container 5 or 8 not closed by the cover 6 or 9. From preferably, the container has a semi-circular section 5.

Dès que le dispositif est introduit dans l'eau, celle-ci remplit le récipient. Le dispositif est acheminé, positionné et fixé partout moyen connu à proximité de l'engin explosif immergé à neutraliser. Le fonctionnement du dispositif immergé reste identique à celui décrit ci-dessus.As soon as the device is introduced into the water, it fills the container. The device is routed, positioned and fixed everywhere known means near the submerged explosive device to be neutralized. The operation of the submerged device remains identical to that described above.

On notera que la protection de l'invention telle qu'elle est décrite ci-dessus s'étend à des dispositifs de neutralisation de charges explosives quelles que soient les dimensions de ses différents éléments constitutifs.It will be noted that the protection of the invention as described above extends to devices for neutralizing explosive charges whatever the dimensions of its various constituent elements.
