Abstract

The device has a pyrotechnic relay (9a) initiated by a detonator (10a). The relay initiates one blasting charge (6a) by projecting a casing (11), surrounding the relay, against an inner wall of a housing (8) of the charge. The relay is connected to another blasting charge (6b) by a detonation wave transmission relay (13). The projected casing has a length such that the initiation of both the blasting charges is concurrent. An independent claim is also included for a warhead for generating fire.

Description

Le domaine technique de l'invention est celui des dispositifs permettant l'initiation d'au moins deux charges explosives à partir d'un seul détonateur.The technical field of the invention is that of devices for initiating at least two charges explosive from a single detonator.

Il est connu, par exemple dans le domaine des explosifs pour les carrières, d'initier plusieurs charges explosives à partir d'un seul détonateur. Ce détonateur est relié aux différentes charges explosives par des cordeaux de transmission d'onde de détonation.It is known, for example in the field of explosives for quarries, to initiate several explosive charges at from a single detonator. This detonator is connected to different explosive charges by cords of detonation wave transmission.

Avec une telle solution, si l'on souhaite initier les différentes charges d'une façon simultanée, il est nécessaire de prévoir des longueurs de cordeaux identiques entre le détonateur et les différentes charges explosives.With such a solution, if one wishes to initiate the different charges in a simultaneous way it is necessary to provide lengths of identical cords between the detonator and the various explosive charges.

Cette solution est mal adaptée à la conception d'un dispositif d'initiation pour une munition, par exemple pour une tête militaire génératrice d'éclats.This solution is poorly adapted to the design of a initiation device for a munition, for example for a military head generating shards.

En effet il est nécessaire alors de loger des longueurs de cordeaux importantes au voisinage du chargement explosif de la munition.Indeed it is necessary then to accommodate lengths large cords in the vicinity of the explosive charge ammunition.

L'invention a pour objet de proposer un dispositif d'initiation de conception simple, compacte et fiable permettant d'assurer l'initiation de deux charges explosives (notamment d'une munition) à partir d'un seul détonateur.The object of the invention is to propose a device Initiation of simple, compact and reliable design to ensure the initiation of two explosive charges (including ammunition) from a single detonator.

Ainsi l'invention a pour objet un dispositif permettant l'initiation d'au moins deux charges explosives à partir d'un seul détonateur, dispositif caractérisé en ce qu'il comprend au moins un premier relais pyrotechnique qui est initié par le détonateur, premier relais qui initie d'une part une première charge explosive par la projection sur celle ci d'une enveloppe et qui est relié d'autre part à une deuxième charge explosive par au moins un relais de transmission d'onde de détonation.Thus, the subject of the invention is a device enabling the initiation of at least two explosive charges from a only detonator, device characterized in that it comprises at least a first pyrotechnic relay which is initiated by the detonator, the first relay which initiates on the one hand a first explosive charge by the projection on this one of an envelope and which is connected on the other hand to a second explosive charge by at least one transmission relay detonation wave.

Selon une autre caractéristique, le parcours de l'enveloppe projetée aura une longueur telle que l'initiation des deux charges explosives sera pratiquement simultanée.According to another characteristic, the course of the projected envelope will have a length such that the initiation both explosive charges will be almost simultaneous.

Avantageusement le premier relais sera cylindrique et entouré par une enveloppe également cylindrique, la projection de l'enveloppe se faisant au travers d'une cavité annulaire aménagée dans la première charge explosive. Advantageously, the first relay will be cylindrical and surrounded by an equally cylindrical envelope, the projection of the envelope through a cavity annular arranged in the first explosive charge.

Par ailleurs il est nécessaire aujourd'hui de concevoir des têtes militaires génératrices d'éclats pouvant avoir plusieurs modes de fonctionnements différents, programmables en fonction des besoins opérationnels.Moreover, it is necessary today to design splinter-generating military heads that may have several different modes of operation, programmable according to operational needs.

On cherche par exemple à réaliser des têtes qui, pour pouvoir détruire une cible renforcée (par exemple une ogive de missile), engendrent une gerbe d'éclats qui est focalisée au voisinage d'un plan radial de la tête militaire. D'une façon classique ces têtes à gerbe focalisée sont obtenues en initiant d'une façon simultanée la tête à ses deux extrémités. On considèrera qu'une initiation est simultanée lorsque l'écart entre les deux initiations est inférieur ou égal à 2 micro secondes.For example, we want to make heads that, for to be able to destroy a reinforced target (eg an ogive missiles), generate a sheaf of shards that is focused in the vicinity of a radial plane of the military head. On the one classic way these focused heads are obtained in initiating a simultaneous way the head to his two ends. We consider that an initiation is simultaneous when the difference between the two initiations is lower or equal to 2 micro seconds.

Pour pouvoir détruire les cibles peu protégées (tels des postes de commandement ou des relais de communications) ces mêmes têtes militaires doivent par ailleurs pouvoir engendrer une gerbe d'éclats omnidirectionnelle. Il est classique de réaliser une telle gerbe par une initiation de la tête au niveau d'une seule de ses extrémités.To be able to destroy poorly protected targets (such as command posts or communications relays) these military heads must also be able to a sheaf of omni-directional shrapnel. It is classic to to realize such a sheaf by an initiation of the head at level of only one of its ends.

Les solutions connues mettent en oeuvre des initiateurs disposés au niveau de chacune des faces d'extrémité de la tête militaire et commandés à partir d'un seul dispositif d'amorçage électronique.Known solutions use initiators arranged at each of the end faces of the military head and commanded from a single device electronic priming.

Ces solutions imposent de réaliser des connexions électriques complexes. Par ailleurs la fiabilité de la simultanéité de l'amorçage est tributaire alors de plusieurs facteurs : la fiabilité du système électronique commandant l'initiation simultanée et la fiabilité de deux initiateurs.These solutions require making connections complex electric. Moreover, the reliability of simultaneity of the priming is then dependent on several factors: the reliability of the electronic system commander the simultaneous initiation and reliability of two initiators.

L'invention a donc également pour objet de proposer une tête militaire de conception simple, compacte et fiable et qui, grâce au dispositif d'initiation selon l'invention peut au choix fonctionner suivant deux modes différents.The object of the invention is therefore also to propose a military head of simple design, compact and reliable and which, thanks to the initiation device according to the invention can alternatively operate in two different modes.

Ainsi invention a également pour objet une tête militaire génératrice d'éclats mettant en oeuvre un dispositif d'initiation tel que décrit précédemment, tête caractérisé en ce qu'elle comprend un bloc d'un explosif de chargement pouvant être initié à l'une ou l'autre de ses extrémités par une première et/ou une deuxième charge explosive d'initiation, la première charge d'initiation pouvant être initiée par la projection d'une enveloppe entourant le premier relais et la deuxième charge explosive d'initiation pouvant être par ailleurs initiée par l'intermédiaire d'au moins un relais de transmission d'onde de détonation la reliant au premier relais.Thus invention also relates to a military head fragment generator using a device of initiation as described above, head characterized in what it includes a block of an explosive loading can be initiated at either end by a first and / or a second explosive charge of initiation, the first initiation charge that can be initiated by the projection of an envelope surrounding the first relay and the second explosive charge of initiation may also be initiated through minus a detonation wave transmission relay the connecting to the first relay.

Le bloc d'explosif de chargement pourra comporter un canal axial à l'intérieur duquel passera le relais de transmission d'onde de détonation.The explosive charge block may include a axial channel within which will pass the relay of detonation wave transmission.

La tête militaire génératrice d'éclats selon l'invention pourra comporter une gaine isolante disposée dans le canal axial et entourant le relais de transmission.The warhead generating splinters according to the invention may comprise an insulating sheath arranged in the channel axial and surrounding the transmission relay.

La tête pourra comprendre un premier détonateur disposé de façon à pouvoir initier le premier relais, premier détonateur qui sera actionné par une fusée d'amorçage.The head may include a first detonator arranged in order to initiate the first relay, first detonator that will be activated by a firing rocket.

Selon une variante, la première charge explosive d'initiation pourra être directement initiée par un deuxième moyen d'amorçage distinct du premier relais.According to a variant, the first explosive charge initiation can be directly initiated by a second separate priming means of the first relay.

Le deuxième moyen d'amorçage pourra comprendre au moins trois amorces détonateurs régulièrement réparties angulairement et disposées en regard d'une couronne de la première charge explosive.The second priming means may comprise at least three regularly distributed detonator primers angularly and arranged opposite a crown of the first explosive charge.

L'invention sera mieux comprise à la lecture de la description qui va suivre d'un mode particulier de réalisation, description faite en référence aux dessins annexés et dans lesquels :

  • la figure 1 est une vue en coupe d'une tête militaire selon l'invention mettant en oeuvre le dispositif d'initiation selon l'invention,
  • les figures 2a et 2b sont deux vues schématisant le fonctionnement de la tête militaire selon l'invention respectivement en mode gerbe d'éclats focalisée et en mode gerbe d'éclats dispersée.
The invention will be better understood on reading the following description of a particular embodiment, a description given with reference to the appended drawings and in which:
  • FIG. 1 is a sectional view of a military head according to the invention embodying the initiation device according to the invention,
  • FIGS. 2a and 2b are two views schematizing the operation of the military head according to the invention respectively in a focused sheaf mode and in a scattered sheaf mode.

En se reportant à la figure 1, une tête militaire 1 selon l'invention comprend un bloc 2 d'un explosif de chargement disposé dans une enveloppe 3 génératrice d'éclats. L'enveloppe 3 est fermée à chaque extrémité par un couvercle 4a, 4b. Le bloc explosif 2 comporte à chacune de ses extrémités une cavité 5a, 5b qui reçoit une charge explosive d'initiation 6a, 6b.Referring to Figure 1, a military head 1 according to the invention comprises a block 2 of a loading explosive disposed in a casing 3 generating chips. The envelope 3 is closed at each end by a cover 4a, 4b. The explosive block 2 includes at each of its ends a cavity 5a, 5b which receives an explosive charge initiation 6a, 6b.

Le bloc 2 comporte par ailleurs un canal axial 7 qui relie les deux cavités 5a et 5b.Block 2 also comprises an axial channel 7 which connects the two cavities 5a and 5b.

La première cavité 5a renferme un comprimé d'une première charge explosive d'initiation 6a. Cette première charge est constituée par exemple par un explosif relativement peu sensible tel qu'un explosif associant le triamino trinitrobenzène et un liant thermoplastique, explosif tel que décrit par le brevet FR2671549. Cette première charge 6a comporte un logement cylindrique 8 à l'intérieur duquel est placé un premier relais de détonation 9a, lui-même disposé en regard d'un premier détonateur 10a. Le relais 9a sera constitué par exemple par un explosif associant hexogène et cire. Ce relais est cylindrique et coaxial au logement 8.The first cavity 5a contains a tablet of a first explosive charge of initiation 6a. This first charge is consisting for example of a relatively low explosive sensitive such as an explosive associating the triamino trinitrobenzene and a thermoplastic, explosive binder such as described by the patent FR2671549. This first charge 6a has a cylindrical housing 8 inside which is placed a first detonation relay 9a, itself arranged in look of a first detonator 10a. Relay 9a will be constituted for example by an explosive combining hexogen and wax. This relay is cylindrical and coaxial with the housing 8.

Le détonateur 10a est relié par une connexion filaire à une fusée d'amorçage 14.The detonator 10a is connected by a wired connection to a firing rocket 14.

Le premier relais 9a est entouré d'une enveloppe 11 cylindrique, par exemple métallique, et qui est destinée à être projetée radialement contre la paroi cylindrique interne du logement 8 lors de l'initiation du premier relais 9a. L'espace 12 séparant l'enveloppe 11 et la première charge 6a pourra être vide ou bien rempli par une couche annulaire de mousse synthétique compressible.The first relay 9a is surrounded by an envelope 11 cylindrical, for example metallic, and which is intended for be projected radially against the internal cylindrical wall housing 8 during the initiation of the first relay 9a. The space 12 separating the envelope 11 and the first load 6a may be empty or filled with an annular layer of compressible synthetic foam.

La projection de l'enveloppe 11 assure ainsi l'initiation de la première charge 6a par le premier relais 9a avec un retard qui dépend du diamètre du logement 8, de la nature et de l'épaisseur de l'enveloppe 11 ainsi que de la présence ou non d'un matériau compressible à l'intérieur de l'espace 12.The projection of the envelope 11 thus ensures initiation of the first load 6a by the first relay 9a with a delay which depends on the diameter of housing 8, nature and the thickness of the envelope 11 as well as the presence or not of a compressible material inside the space 12.

De plus une rondelle 21 (par exemple métallique) est interposée entre l'extrémité du relais 9a et la charge explosive d'initiation 6a. Cette rondelle permet d'éviter une initiation axiale directe de la charge 6a par le relais 9a.In addition a washer 21 (for example metallic) is interposed between the end of relay 9a and the load explosive initiation 6a. This washer avoids a direct axial initiation of the load 6a by the relay 9a.

La deuxième charge explosive d'initiation 6b a la même composition que la première charge 6a. Elle est par ailleurs initiée par un deuxième relais de détonation 9b qui est lui-même initié par le premier relais 9a et par l'intermédiaire d'un relais de transmission d'onde de détonation 13, interposé entre les deux relais 9a et 9b.The second explosive charge of initiation 6b has the same composition as the first charge 6a. She is also initiated by a second detonation relay 9b which is itself initiated by the first relay 9a and through of a detonation wave transmission relay 13, interposed between the two relays 9a and 9b.

Les relais de transmission sont bien connus de l'Homme du Métier. Ils comprennent généralement un tube 13a en matière plastique renfermant une fine couche d'explosif et portant à chaque extrémité un relais 13b, 13c.Transmission relays are well known to humans Job. They generally comprise a tube 13a made of plastic material containing a thin layer of explosive and each end a relay 13b, 13c.

Ces cordeaux assurent une transmission d'onde de détonation entre deux relais avec une vitesse de l'ordre de 7000 m/s.These cords ensure a wave transmission of detonation between two relays with a speed of about 7000 m / s.

Le cordeau 13 est séparé du bloc d'explosif 2 par une gaine isolante 15 qui est disposée dans le canal axial 7 et qui entoure le relais de transmission 13.The cord 13 is separated from the explosive block 2 by a insulating sheath 15 which is arranged in the axial channel 7 and surrounding the transmission relay 13.

Cette gaine est réalisée par exemple en matière plastique. Elle a pour fonction de protéger le bloc explosif 2 contre les projections issues du cordeau 13.This sheath is made for example of material plastic. Its function is to protect the explosive block 2 against the projections from the cord 13.

Selon une autre caractéristique de la tête militaire selon l'invention, la première charge explosive d'initiation 6a peut être directement initiée par un deuxième moyen d'amorçage distinct du premier relais 9a.According to another characteristic of the military head according to the invention, the first explosive charge of initiation 6a can be directly initiated by a second means separate ignition of the first relay 9a.

Ce deuxième moyen d'amorçage comprend ici au moins trois amorces détonateurs 10b, régulièrement réparties angulairement, et disposées en regard d'une couronne 16 de la première charge explosive 6a.This second priming means here comprises at least three 10b detonator primers, regularly distributed angularly, and arranged opposite a crown 16 of the first explosive charge 6a.

Les trois détonateurs périphériques 10b sont portés (tout comme le premier détonateur 10a) par un support 17 solidaire du couvercle 4a. Elles sont reliées (comme le détonateur 10a) à la fusée d'amorçage 14 par des liaisons filaires.The three 10b peripheral detonators are worn (all as the first detonator 10a) by a solidarity support 17 cover 4a. They are connected (like detonator 10a) to the firing rocket 14 by wire links.

Le fonctionnement de la tête militaire 1 et de son dispositif d'initiation va être maintenant décrit en référence aux figures 2a et 2b.The operation of the military head 1 and its initiation device will now be described in reference to Figures 2a and 2b.

La figure 2a montre un fonctionnement, de la tête militaire 1 en mode "gerbe d'éclats focalisée". La fusée d'amorçage commande alors l'initiation du détonateur axial 10a.Figure 2a shows an operation, of the head military 1 in "focused shrapnel" mode. The rocket priming then controls the initiation of the axial detonator 10a.

Le premier relais 9a est alors initié et il initie à son tour la deuxième charge explosive 6b par l'intermédiaire du relais de transmission 13 et du deuxième relais 9b. The first relay 9a is then initiated and he initiates to his turn the second explosive charge 6b through the transmission relay 13 and second relay 9b.

Parallèlement l'initiation du premier relais 9a provoque la projection de l'enveloppe 11 au travers de l'espace 12.At the same time, the initiation of the first relay 9a provokes the projection of the envelope 11 through the space 12.

Cette enveloppe impacte contre la surface cylindrique interne du logement 8. Le choc provoque alors l'initiation de la première charge explosive 6a.This envelope impacts against the cylindrical surface 8. The shock then provokes the initiation of the first explosive charge 6a.

La vitesse de projection de l'enveloppe 11 est de l'ordre de 2000 m/s alors que la vitesse de détonation au travers du relais de transmission 13 et du deuxième relais 9b est de l'ordre de 7000 m/s. Or le chemin à parcourir par l'enveloppe 11 projetée est bien inférieur au chemin à parcourir par l'onde de détonation conduite par le relais axial 13.The projection speed of the envelope 11 is of the order of 2000 m / s while the speed of detonation through the transmission relay 13 and the second relay 9b is the order of 7000 m / s. Now the way to go through the envelope 11 projected is well below the path to be covered by the detonation wave driven by the axial relay 13.

Du fait des écarts de vitesse, il est donc possible de dimensionner le dispositif de telle sorte qu'il y ait une initiation simultanée des deux charges explosives 6a et 6b.Due to speed differences, it is therefore possible to size the device so that there is a simultaneous initiation of the two explosive charges 6a and 6b.

On considèrera qu'une initiation de deux charges est simultanée lorsque l'écart entre les deux initiations est inférieur ou égal à 2 micro secondes.We consider that an initiation of two charges is simultaneous when the gap between the two initiations is less than or equal to 2 micro seconds.

L'Homme du Métier dimensionnera aisément un tel dispositif d'initiation en jouant notamment sur le diamètre du logement 8, sur l'épaisseur de l'enveloppe projetée 11, sur la masse du premier relais 9a ainsi que sur la présence ou non d'un matériau de remplissage dans l'espace 12.The skilled person will easily size such initiation device by playing in particular on the diameter of the housing 8, on the thickness of the projected casing 11, on the mass of the first relay 9a as well as on the presence or not of a filling material in the space 12.

Les deux charges explosives d'initiation 6a et 6b étant initiées simultanément, le bloc explosif 2 se trouve initié à ses deux extrémités et deux fronts d'ondes de détonation 18a et 18b se propagent dans le bloc explosif 2 suivant des directions qui convergent vers un plan médian 19, conduisant à une projection des éclats de l'enveloppe 3 en direction de ce plan médian 19 (les flèches E schématisent les vitesses de projection des éclats).The two explosive initiation charges 6a and 6b being initiated simultaneously, the explosive block 2 is initiated in its two ends and two detonation wave fronts 18a and 18b propagate in the explosive block 2 according to directions that converge to a midplane 19, leading to a projection of the fragments of the envelope 3 in the direction of this median plane 19 (the arrows E schematize the speeds of projection of splinters).

La figure 2b montre le fonctionnement de la tête militaire 1 en mode "gerbe d'éclats dispersée". La fusée d'amorçage 14 commande alors l'initiation de la couronne de détonateurs périphériques 10b.Figure 2b shows the operation of the head Military 1 in "scattered sheaf" mode. The rocket boot 14 then commands the initiation of the crown of 10b peripheral detonators.

Ces détonateurs initient alors directement la première charge explosive 6a. Le premier relais 9a n'est pas initié. Un seul front d'ondes de détonation 18c progresse alors dans le bloc explosif 2. Il en résulte une dispersion des éclats d'une façon relativement homogène dans un volume cylindrique autour de l'axe 20 de la tête militaire.These detonators then directly initiate the first explosive charge 6a. The first relay 9a is not initiated. A single detonation wavefront 18c then progresses in the explosive block 2. The result is a dispersion of the fragments in a relatively homogeneous manner in a cylindrical volume around the axis 20 of the military head.

Différentes variantes sont possibles sans sortir du cadre de l'invention.Different variants are possible without going outside the box of the invention.

Il est ainsi possible de remplacer les détonateurs périphériques 10b par un dispositif d'amorçage ne comportant qu'un seul détonateur axial 10a et un écran mobile (non représenté) susceptible de se placer dans le logement 8, interposé entre l'enveloppe 11 et la première charge explosive 6a.It is thus possible to replace the detonators devices 10b by a boot device having no only one axial detonator 10a and a movable screen (no represented) which can be placed in the housing 8, interposed between the envelope 11 and the first load explosive 6a.

Dans ce cas lorsque l'on veut faire fonctionner la tête militaire en mode "gerbe focalisée" on procède comme décrit précédemment en référence à la figure 2a.In this case when we want to make the head work military mode "focused sheaf" proceed as described previously with reference to Figure 2a.

Lorsque l'on veut faire fonctionner la tête militaire en mode "gerbe dispersée" on positionne (avant l'initiation) l'écran dans le logement 8. Ce positionnement pourra être réalisé à l'aide d'un actionneur approprié (tel un moteur pas à pas).When we want to make the military head work mode "scattered sheaf" one positions (before the initiation) the screen in slot 8. This positioning can be realized with the help of an appropriate actuator (such as a motor step by step).

Lorsque le détonateur est initié, il commande alors l'initiation de la deuxième charge explosive 6b par l'intermédiaire du relais de transmission 13 et du deuxième relais 9b.When the detonator is initiated, it then commands the initiation of the second explosive charge 6b by through the transmission relay 13 and the second relay 9b.

En raison de la présence de l'écran, l'enveloppe 11 ne peut être projetée sur la première charge explosive 6a. Le bloc explosif 2 ne se trouve donc initié qu'à partir d'une seule extrémité par la deuxième charge explosive 6b.Due to the presence of the screen, the envelope 11 does not can be projected on the first explosive charge 6a. The explosive block 2 is thus only initiated from a only end by the second explosive charge 6b.

Il en résulte une dispersion des éclats avec une orientation qui est la symétrique par rapport à un plan médian 19 de celle qui est représentée figure 2b.This results in a dispersion of the chips with a orientation which is symmetrical with respect to a plane median 19 of that shown in Figure 2b.
