Description

Le domaine de la présente invention est celui des dispositifs permettant d'éjecter sur trajectoire et suivant une direction radiale d'un vecteur, des conteneurs disposés à l'intérieur de l'enveloppe de ce dernier.The field of the present invention is that of devices making it possible to eject, on a trajectory and in a radial direction from a vector, containers placed inside the envelope of the latter.

Il faut entendre par vecteur un mobile suivant une trajectoire propre que ce soit après tir à partir d'un lanceur (dans ce cas le vecteur sera un projectile tel une roquette), ou après largage à partir d'un aéronef (bombe, transporteur de sous-munition).A vector is understood to mean a mobile on its own trajectory, whether after firing from a launcher (in this case the vector will be a projectile such as a rocket), or after dropping from an aircraft (bomb, transporter of submunition).

Les vecteurs éjectant des conteneurs sur trajectoire sont aujourd'hui relativement répandus. On les utilise aussi bien pour la dispersion de sous-projectiles autonomes dotés de dispositifs autodirecteurs et aptes à rechercher chacun leur cible, que pour la dissémination de mines ou bombelettes anti-véhicules ou anti-personnels.Vectors ejecting containers on a trajectory are relatively widespread today. They are used both for dispersing autonomous sub-projectiles equipped with homing devices and capable of each seeking their target, as for the dissemination of mines or anti-vehicle or anti-personnel bombs.

L'efficacité de tels vecteurs est directement liée à la bonne dispersion des conteneurs, en effet il est totalement exclu de voir ces derniers interférer entre eux au moment de leur libération (dans le cas de sous-projectile devant poursuivre une trajectoire propre), ou encore tomber au sol de façon groupée (dans le cas de mines).The effectiveness of such vectors is directly linked to the good dispersion of the containers, in fact it is completely excluded from seeing them interfering with each other at the time of their release (in the case of a sub-projectile having to pursue its own trajectory), or still fall to the ground in a grouped fashion (in the case of mines).

Afin d'éviter de tels inconvénients on a cherché à assurer une éjection radiale rapide et avec une vitesse initiale importante.In order to avoid such drawbacks, attempts have been made to ensure rapid radial ejection with a high initial speed.

Le brevet EP0169956 décrit un premier type de solution dans laquelle les sous-projectiles sont maintenus solidaires d'un support annulaire au moyen de brides à verrou.Patent EP0169956 describes a first type of solution in which the sub-projectiles are held integral with an annular support by means of bolt flanges.

Après élimination de l'enveloppe externe, une charge génératrice de gaz est initiée et provoque d'une part la libération des verrous et d'autre part l'éjection des sous-projectiles par des pistons.After elimination of the external envelope, a charge generating gas is initiated and causes on the one hand the release of the latches and on the other hand the ejection of the sub-projectiles by pistons.

Un tel dispositif d'éjection est très complexe ce qui augmente les risques de disfonctionnements. De plus la vitesse d'éjection est limitée par l'inertie des pièces mécaniques en présence, et se trouve également liée à l'élasticité du verrou de blocage qui est maintenu en contrainte pendant tout le temps de stockage du vecteur, des pertes de caractéristiques mécaniques sont donc à craindre ce qui diminue la fiabilité de ce dispositif.Such an ejection device is very complex, which increases the risk of malfunctions. In addition, the speed of ejection is limited by the inertia of the mechanical parts present, and is also linked to the elasticity of the locking bolt which is maintained in constrained during the entire storage time of the vector, losses of mechanical characteristics are therefore to be feared, which reduces the reliability of this device.

Les brevets FR2591,35, EP0265608 et EP0265609 décrivent d'autres dispositifs d'éjection dans lesquels une charge génératrice de gaz disposée au niveau de l'axe du vecteur gonfle un ou plusieurs sacs.The patents FR2591.35, EP0265608 and EP0265609 describe other ejection devices in which a gas-generating charge placed at the level of the axis of the vector inflates one or more bags.

Un tel dispositif est limité du point de vue de la vitesse d'éjection par le temps nécessaire pour gonfler les sacs. En outre, les sacs souples étant conservés repliés à l'intérieur du vecteur, une dégradation de leurs caractéristiques mécaniques est à craindre, pouvant entraîner soit une dissymétrie du gonflage, donc de l'éjection, soit une rupture de l'un des sacs interdisant ainsi la dispersion.Such a device is limited from the point of view of the speed of ejection by the time necessary to inflate the bags. In addition, the flexible bags being kept folded inside the vector, a deterioration in their mechanical characteristics is to be feared, which could cause either an asymmetry of the inflation, therefore of the ejection, or a rupture of one of the bags preventing thus the dispersion.

C'est le but de la présente invention que de proposer un dispositif d'éjection qui assure la symétrie de la répartition des conteneurs et une grande vitesse d'éjection tout en conservant un très haut niveau de fiabilité.It is the aim of the present invention to propose an ejection device which ensures symmetry of the distribution of the containers and a high ejection speed while maintaining a very high level of reliability.

Ainsi l'invention a pour objet un dispositif d'éjection, sur trajectoire et suivant une direction radiale, de conteneurs disposés en couronne à l'intérieur de l'enveloppe d'un vecteur, dispositif caractérisé en ce qu'il comprend d'une part une charge détonante disposée au niveau de l'axe du vecteur et s'étendant sensiblement sur toute la longueur de l'ensemble des conteneurs, et d'autre part des moyens assurant le confinement de cette charge, et en ce que les conteneurs sont maintenus en contact ou solidaires des moyens de confinement par des moyens de maintien au moment de l'initiation de la charge détonante, la surface de contact ou commune étant telle que sa trace en coupe radiale ait une médiatrice ayant une direction radiale relativement au vecteur.Thus, the subject of the invention is a device for ejecting, on a trajectory and in a radial direction, containers arranged in a ring inside the envelope of a vector, a device characterized in that it comprises a firstly a detonating charge placed at the level of the axis of the vector and extending substantially over the entire length of all the containers, and secondly means ensuring the confinement of this charge, and in that the containers are kept in contact or integral with the confinement means by holding means at the time of initiation of the detonating charge, the contact or common surface being such that its trace in radial section has a mediator having a radial direction relative to the vector.

Les moyens de confinement peuvent comprendre une cavité constituée par la juxtaposition des différents conteneurs.The containment means may include a cavity formed by the juxtaposition of the different containers.

Les moyens de confinement peuvent également comprendre un étui qui est en contact avec les conteneurs.The containment means may also include a case which is in contact with the containers.

Selon un mode particulier de réalisation, dans le cas où les conteneurs présentent chacun au moins deux faces planes séparées par une surface intermédiaire limitant la cavité, les faces planes de deux conteneurs adjacents sont maintenues en contact mutuel par les moyens de maintien et sont orientées radialement relativement au vecteur, et en coupe radiale, l'angle formé par les traces des deux faces planes de chaque conteneur a pour bissectrice la médiatrice de la trace de la surface intermédiaire du conteneur considéré.According to a particular embodiment, in the case where the containers each have at least two flat faces separated by an intermediate surface limiting the cavity, the flat faces of two adjacent containers are kept in mutual contact by the holding means and are oriented radially relatively to the vector, and in radial section, the angle formed by the traces of the two flat faces of each container has for bisector the mediator of the trace of the intermediate surface of the container considered.

Les moyens de fragmentation pourront comprendre des cordeaux de découpe disposés en regard de l'enveloppe le long d'une direction axiale du vecteur,par exemple dans le prolongement des faces planes des conteneurs.The fragmentation means may include cutting cords arranged facing the envelope along an axial direction of the vector, for example in the extension of the flat faces of the containers.

Les moyens de maintien pourront comprendre au moins une bande cylindrique entourant l'ensemble des conteneurs et disposée de façon à être rompue par les cordeaux de découpe.The holding means may comprise at least one cylindrical strip surrounding all of the containers and arranged so as to be broken by the cutting cords.

Le dispositif selon l'invention comprendra de façon préferentielle un système d'allumage dont la mise à feu est commandée par une fusée et qui provoque l'initiation des cordeaux de découpe puis de la charge détonante par l'intermédiaire d'un retard.The device according to the invention will preferably include an ignition system, the firing of which is controlled by a rocket and which causes the initiation of the cutting cords then of the detonating charge by means of a delay.

L'invention pourra être appliquée à un vecteur tel que l'ensemble des conteneurs présente une symétrie de rotation d'ordre trois relativement à son axe, et que les conteneurs sont des mines.The invention may be applied to a vector such that all of the containers have rotational symmetry of order three relative to its axis, and that the containers are mines.

L'invention sera mieux comprise à la lecture de la description qui va suivre de modes particuliers de réalisation, description faite en référence aux dessins annexés dans lesquels:

  • La Figure 1 est une vue schématique en coupe axiale d'un vecteur disperseur de conteneurs équipé d'un dispositif d'éjection selon un premier mode de réalisation de l'invention.
  • La Figure 2 est une vue en coupe suivant le plan A-A de la Figure 1.
  • La Figure 3 est une vue en coupe radiale d'un vecteur équipé d'un dispositif d'éjection selon un deuxième mode de réalisation de l'invention.
The invention will be better understood on reading the description which follows of particular embodiments, description made with reference to the appended drawings in which:
  • Figure 1 is a schematic view in axial section of a container dispersing vector equipped with an ejection device according to a first embodiment of the invention.
  • Figure 2 is a sectional view along the plane AA of Figure 1.
  • Figure 3 is a radial sectional view of a vector equipped with an ejection device according to a second embodiment of the invention.

En se reportant à la Figure 1, un vecteur 1, qui est un projectile à vitesse de rotation réduite tel une roquette, comprend une partie arrière 15 sur laquelle sera disposé un empennage non représenté, une enveloppe 3, et une ogive 14 contenant une fusée 20 ainsi qu'un système d'allumage qui sera décrit plus en détail par la suite.Referring to Figure 1, a vector 1, which is a projectile with reduced speed of rotation such as a rocket, comprises a rear part 15 on which will be arranged a tail unit not shown, an envelope 3, and a warhead 14 containing a rocket 20 as well as an ignition system which will be described in more detail below.

L'enveloppe 3 renferme un certain nombre de conteneurs 2 qui sont ici des mines dispersables, du type par exemple de celles décrites dans les brevets FR2475716 et FR2448708.The envelope 3 contains a number of containers 2 which are here dispersible mines, of the type for example of those described in patents FR2475716 and FR2448708.

La structure interne de ces mines ne fait pas l'objet de la présente demande et ne sera donc pas décrite plus en détail.The internal structure of these mines is not the subject of the present request and will therefore not be described in more detail.

En se reportant à la Figure 2 qui est une coupe de la précédente suivant une direction radiale, on voit que les mines sont disposées en couronne autour de l'axe du vecteur. L'enveloppe contient ainsi un empilement de plusieurs couches, chaque couche étant constituée par un groupe de trois mines régulièrement réparties autour de l'axe du vecteur.Referring to Figure 2 which is a section of the previous in a radial direction, we see that the mines are arranged in a ring around the axis of the vector. The envelope thus contains a stack of several layers, each layer being constituted by a group of three mines regularly distributed around the axis of the vector.

Chaque mine comporte au moins deux faces planes latérales 9 séparées par une surface dite intermédiaire 6. Les faces planes des différentes mines constituant un groupe de trois sont maintenues en contact mutuel par des moyens de maintien quï comprennent une bande métallique 11 sensiblement cylindrique entourant chaque groupe de trois mines.Each mine has at least two lateral flat faces 9 separated by a so-called intermediate surface 6. The flat faces of the different mines constituting a group of three are kept in mutual contact by holding means which comprise a substantially cylindrical metal strip 11 surrounding each group of three mines.

Les moyens de maintien comprennent également des entretoises triangulaires 12 qui viennent s'intercaler entre chaque groupe de trois mines et qui sont disposées dans des entailles 16 réalisées sur les mines.The holding means also comprise triangular spacers 12 which are inserted between each group of three mines and which are arranged in notches 16 made on the mines.

Il subsiste un jeu relatif suivant la direction axiale du vecteur entre entretoises et mines de telle sorte que les mines appartenant à deux groupes successifs soient mutuel­lement en contact au niveau de leurs faces supérieures 18 et inférieures 19 respectives.There remains a relative clearance in the axial direction of the vector between spacers and mines so that the mines belonging to two successive groups are in mutual contact at their upper 18 and lower 19 respective faces.

Ces entretoises assurent la solidarisation en rotation des mines constituant un groupe à la fois entre elles et avec celles du groupe suivant.These spacers ensure the joining in rotation of the mines constituting a group both between themselves and with those of the following group.

Un logement 17 est aménagé au niveau des sommets de chaque entretoise 12. Une cale longitudinale 13, s'étendant sur sensiblement toute la longueur du vecteur 1, est disposée au niveau de chaque groupe de logements superposés.A housing 17 is arranged at the tops of each spacer 12. A longitudinal wedge 13, extending over substantially the entire length of the vector 1, is arranged at each group of overlapping housings.

Les cales portent des moyens de fragmentation de l'enveloppe 3 qui sont constitués ici par des cordeaux de découpe longitudinale 10 de type connu (par exemple des cordeaux d'hexogène sous gaine plomb).The wedges carry means for fragmenting the envelope 3 which here consist of longitudinal cutting cords 10 of known type (for example hexogen cords under lead sheath).

Deux cordeaux de découpe circulaire 24 (seul le cordeau avant est représenté), disposés à la partie avant et arrière du vecteur, sont destinés à séparer l'ogive 14 et la partie arrière 15 du reste du vecteur et complètent les moyens de fragmentation de l'enveloppe.Two circular cutting lines 24 (only the front line is shown), arranged at the front and rear part of the vector, are intended to separate the warhead 14 and the rear part 15 from the rest of the vector and complete the means for fragmenting the 'envelope.

Les bandes metalliques 11 rendent solidaires les cordeaux de découpe 10 et les cales longitudinales 13 de l'ensemble formé par les entretoises 12 et les mines 2.The metal strips 11 make the cutting cords 10 and the longitudinal wedges 13 integral with the assembly formed by the spacers 12 and the leads 2.

Les moyens de maintien ainsi décrits rendent donc solidaires l'ensemble des mines et les moyens de découpe. Le sous-ensemble ainsi constitué est rendu solidaire du vecteur en rotation et en translation d'une façon classique et non représentée en détail.The holding means thus described therefore make all the mines and the cutting means integral. The subassembly thus formed is made integral with the vector in rotation and in translation in a conventional manner and not shown in detail.

On pourra par exemple, pour réaliser la liaison en rotation, prévoir des goupilles d'entraînement disposées entre la partie arrière 15 et l'entretoise 12 du premier groupe de mines.For example, to make the connection in rotation, provide drive pins disposed between the rear part 15 and the spacer 12 of the first group of mines.

Le dernier groupe de mine (du côté de l'ogive 14) vient en appui sur un couvercle 25 qui porte le cordeau circulaire 24 dans une gorge périphérique et qui est rendu solidaire de l'ogive et del'enveloppe par exemple par des goupilles radiales.The last group of mines (on the side of the warhead 14) comes to bear on a cover 25 which carries the circular cord 24 in a peripheral groove and which is made integral with the warhead and the casing for example by radial pins .

Le couvercle porte des entailles lui permettant de recevoir l'entretoise 12 qui assure sa liaison en rotation avec le dernier groupe de mines. Il porte également un orifice 26 permettant le passage d'un cordeau d'héxogène qui constitue une charge détonante 4 dont la fonction sera étudiée ci-après, des moyens d'étanchéité (ici des joints toriques) sont interposés entre l'orifice 26 et la charge 4.The cover carries notches allowing it to receive the spacer 12 which ensures its connection in rotation with the last group of mines. It also carries an orifice 26 allowing the passage of a line of hexogen which constitutes a detonating charge 4 whose function will be studied below, sealing means (here O-rings) are interposed between the orifice 26 and the charge 4.

La solidarisation en translation de l'enveloppe avec l'ensemble des mines sera donc assurée par l'appui des faces supérieures du dernier groupe de mines sur le couvercle 25 ainsi que par l'appui du premier groupe de mines sur la partie arrière 15.The joining in translation of the envelope with all the mines will therefore be ensured by the support of the upper faces of the last group of mines on the cover 25 as well as by the support of the first group of mines on the rear part 15.

La partie arrière portera le deuxième cordeau de découpe circulaire par exemple au niveau d'une gorge circulaire aménagée sur un deuxième couvercle analogue au couvercle 25 mais ne comportant pas d'orifice de passage pour la charge détonante.The rear part will carry the second circular cutting cord, for example at the level of a circular groove arranged on a second cover similar to the cover 25 but having no passage orifice for the detonating charge.

Les mines ainsi solidarisées laissent subsister sensiblement au niveau de l'axe du vecteur une cavité 5 à section triangulaire qui est délimitée principalement par la juxtaposition des différentes surfaces intermédiaires 6 de chacune des mines ainsi que des surfaces latérales des entretoises 12.The mines thus joined together leave substantially at the level of the axis of the vector a cavity 5 of triangular section which is delimited mainly by the juxtaposition of the various intermediate surfaces 6 of each of the mines as well as the lateral surfaces of the spacers 12.

Les mines empilées présentent des surfaces de contact relatives, d'une part entre les mines constituant un groupe de trois (faces planes 9), et d'autre part entre les différents groupes de mines (faces supérieures 18 et inférieures 19).The stacked mines have relative contact surfaces, on the one hand between the mines constituting a group of three (flat faces 9), and on the other hand between the different groups of mines (upper faces 18 and lower 19).

La charge détonante 4 est disposée à l'intérieur de la cavité 5 et elle s'étend sensiblement sur toute la longueur de la cavité 5 donc sur toute la longueur de l'ensemble des mines.The detonating charge 4 is disposed inside the cavity 5 and it extends substantially over the entire length of the cavity 5, therefore over the entire length of all the mines.

La cavité 5 ainsi délimitée constitue un moyen de confinement pour la charge détonante 4.The cavity 5 thus delimited constitutes a means of confinement for the detonating charge 4.

Les moyens de confinement sont complétés par le couvercle 25 portant les moyens d'étanchéité ainsi que par le couvercle fermé disposé au niveau du culot.The confinement means are completed by the cover 25 carrying the sealing means as well as by the closed cover disposed at the level of the base.

Les mines, en délimitant la cavité 5 par leurs surfaces intermédiaires 6, sont solidaires du moyen de confinement ainsi crée.The mines, by delimiting the cavity 5 by their intermediate surfaces 6, are integral with the confinement means thus created.

La surface intermédiaire 6 de chaque mine présente une médiatrice, repérée en , dont la direction est radiale relativement au vecteur. Cette médiatrice 7 est de plus la bissectrice de l'angle formé par les faces planes 9 de la mine considérée.The intermediate surface 6 of each mine has a perpendicular bisector, marked at, whose direction is radial relative to the vector. This perpendicular bisector 7 is moreover the bisector of the angle formed by the planar faces 9 of the mine considered.

Les entretoises 7 ont une orientation angulaire relative­ment aux groupes de mines qui est telle que les cordeaux de découpe 10 se trouvent disposés dans le prolongement des faces planes 9 des mines.The spacers 7 have an angular orientation relative to the groups of mines which is such that the cutting cords 10 are arranged in the extension of the planar faces 9 of the mines.

La Figure 1 représente également schématiquement le système d'allumage des cordeaux de découpe 10 ainsi que de la charge détonante 4.FIG. 1 also schematically represents the ignition system of the cutting cords 10 as well as the detonating charge 4.

Le système d'allumage comprend un premier relais 21 qui est initié par la fusée 20, un système à retard 22, constitué ici par une composition pyrotechnique retarda­trice, mais tout autre type de retard en particulier élec­tronique pourrait être envisagé, et un deuxième relais 23.The ignition system comprises a first relay 21 which is initiated by the rocket 20, a delay system 22, here constituted by a retarding pyrotechnic composition, but any other type of delay, in particular electronic delay, could be envisaged, and a second relay 23 .

Le premier relais 21 comprend trois sorties radiales correspondant aux trois cordeaux de découpe 10.The first relay 21 includes three radial outputs corresponding to the three cutting cords 10.

Le deuxième relais 23 est relié à la charge détonante 4.The second relay 23 is connected to the detonating charge 4.

Le système à retard permet d'assurer que la fragmentation de l'enveloppe du projectile soit amorcée avant l'initiation de la charge détonante 4.The delay system ensures that the fragmentation of the projectile envelope is initiated before the initiation of the detonating charge 4.

La valeur du retard sera fonction des célérités des explosifs utilisés pour les cordeaux de découpe et pour la charge détonante, ainsi que de la distance entre le premier relais 21 et les génératrices du vecteur qui sont découpées.The value of the delay will depend on the speed of the explosives used for the cutting cords and for the detonating charge, as well as the distance between the first relay 21 and the generators of the vector which are cut.

Dans le cas habituel d'un projectile à faible vitesse de rotation (de l'ordre de dix tours secondes), un retard compris entre 50 et 100 millisecondes est suffisant pour garantir que le confinement est encore effectif au moment où la charge détonante est initiée.In the usual case of a projectile with low speed of rotation (of the order of ten revolutions seconds), a delay of between 50 and 100 milliseconds is sufficient to guarantee that the confinement is still effective at the moment when the detonating charge is initiated .

Le fonctionnement du vecteur est le suivant, la fusée 20 du type chronométrique provoque l'initiation du premier relais 21 à l'issue d'un temps programmé avant le tir ou commandé sur trajectoire, les trois cordeaux de découpe longitudinaux sont alors initiés simultanément ainsi que la composition à retard 22.The operation of the vector is as follows, the rocket 20 of the chronometric type causes the initiation of the first relay 21 at the end of a time programmed before the firing or controlled on trajectory, the three longitudinal cutting lines are then initiated simultaneously thus than the delay composition 22.

Des raccords en té de type connus et non représentés qui sont solidaires du couvercle 25 assureront l'initiation du cordeau de découpe circulaire 24, par un ou plusieurs des cordeaux longitudinaux 10.Tee fittings of known type and not shown which are integral with the cover 25 will ensure the initiation of the circular cutting cord 24, by one or more of the longitudinal cords 10.

Des raccords analogues permettront l'initiation du cordeau circulaire situé au niveau du culot.Similar connections will allow the initiation of the circular cord located at the base.

Les cordeaux de découpe 10, fragmentent dans le même temps l'enveloppe du vecteur et les bandes cylindriques 11.The cutting cords 10, at the same time fragment the envelope of the vector and the cylindrical bands 11.

A l'issue de la combustion du retard 22, la charge détonante 4 est initiée à son tour.At the end of the combustion of the delay 22, the detonating charge 4 is initiated in turn.

En choisissant une valeur du retard telle que décrite précedemment, la détonation de la charge 4 intervient avant que les mines n'aient commencé à s'écarter les unes des autres sous l'effet de la force centrifuge, et elle entraîne une violente onde de choc à direction radiale qui s'exerce sur les surfaces intermédiaires 6 de chacune des mines.By choosing a delay value as described above, the detonation of the charge 4 occurs before the mines have started to move apart from each other under the effect of centrifugal force, and it causes a violent wave of radial direction impact which is exerted on the intermediate surfaces 6 of each of the mines.

Les médiatrices des surfaces intermédiaires étant également les bissectrices des angles formés par les faces planes 9 de chacune des mines, ces dernières se trouvent dispersées dans une direction radiale, et l'énergie de l'onde de choc est utilisée de façon optimale.The perpendicular bisectors of the intermediate surfaces also being the bisectors of the angles formed by the planar faces 9 of each of the mines, the latter are dispersed in a radial direction, and the energy of the shock wave is used optimally.

On a effectué un certain nombre d'essais avec une charge détonante sous la forme d'un cordeau d'hexogène sous gaine plomb, associé à des cordeaux de découpe également en héxogène sous plomb (célérités de détonation de l'ordre de 7000 m/s).A number of tests were carried out with a detonating charge in the form of a lead sheath with a lead sheath, associated with cutting leads also in lead lead with a detonation velocity of the order of 7000 m / s).

En faisant varier la concentration linéique d'héxogène entre 3 et 40 grammes/mètre, on a obtenu des vitesses d'éjection des mines comprises entre 3 et 30 mètres/seconde, la masse de chaque mine étant de l'ordre de 2 Kilogrammes.By varying the linear concentration of hexogen between 3 and 40 grams / meter, mine ejection speeds were obtained between 3 and 30 meters / second, the mass of each mine being of the order of 2 kilograms.

Il convient de noter l'aspect relativement inhabituel de l'utilisation qui est faite ici des cordeaux détonants. En effet ces derniers sont ordinairement utilisés pour transmettre entre leurs extrémités une information sous la forme d'une onde de détonation.Note the relatively unusual aspect of the use made of detonating cords here. In fact, the latter are usually used to transmit information between their ends in the form of a detonation wave.

On utilise ici un effet radial accessoire qui peut effectivement être exploité en raison de la présence de moyens de confinement.An accessory radial effect is used here which can effectively be exploited due to the presence of containment means.

Il est possible de choisir des compositions pyro­techniques différentes pour réaliser la charge détonante, à condition que cette composition ait effectivement un régime détonant (célérité de l'ordre de 7000 m/s).It is possible to choose different pyrotechnic compositions for carrying out the detonating charge, provided that this composition actually has an detonating regime (speed of the order of 7000 m / s).

Il serait possible d'utiliser des compositions de célérité différentes pour les cordeaux de découpe et pour la charge détonante, dans ce cas on jouera sur la valeur du retard donné par la composition 22.It would be possible to use compositions of different speed for the cutting cords and for the detonating charge, in this case we will play on the value of the delay given by the composition 22.

Il sera possible également d'interposer un matériau amortisseur entre la charge détonante et les surfaces intermédiaires 6 délimitant le confinement. On poura alors, en jouant sur les caractéristiques de compressibilité et d'amortissement de transmission de l'onde de choc de ce matériau, utiliser des charges détonantes plus violentes, ou bien encore moduler la valeur des vitesses d'ejection des mines sans modifier la charge détonante.It will also be possible to interpose a damping material between the detonating charge and the intermediate surfaces 6 delimiting the confinement. We can then, by playing on the compressibility and damping characteristics of the shock wave transmission of this material, use more violent detonating charges, or even modulate the value of mine ejection speeds without modifying the explosive charge.

Il est possible d'utiliser le dispositif selon l'invention pour l'éjection de conteneurs ayant un profil géométrique quelconque.It is possible to use the device according to the invention for the ejection of containers having any geometric profile.

La Figure 3 représente en coupe radiale un vecteur destiné a éjecter sur trajectoire des mines cylindriques 2.Figure 3 shows in radial section a vector intended to eject cylindrical mines 2 on the trajectory.

Ces mines sont empilées à l'intérieur de l'enveloppe 3 du vecteur et sont, comme dans la variante précédente, disposées en couronne autour de l'axe de celui-ci.These mines are stacked inside the envelope 3 of the vector and are, as in the previous variant, arranged in a ring around the axis thereof.

L'enveloppe contient ainsi un empilement de plusieurs groupes de mines, chaque groupe comprennant trois mines régulièrement réparties autour de l'axe du vecteur.The envelope thus contains a stack of several groups of mines, each group comprising three mines regularly distributed around the axis of the vector.

Les moyens de maintien comprennent comme précédemment trois cales longitudinales 13, qui sont dans ce cas en contact avec la surface cylindrique externe des mines, ainsi que des bandes cylindriques 11.The holding means as before comprise three longitudinal wedges 13, which in this case are in contact with the external cylindrical surface of the mines, as well as cylindrical bands 11.

La solidarisation en rotation de l'enveloppe avec l'ensemble des mines et des moyens de maintien est réalisée de façon connue non représentée, par exemple par des clavettes solidaires de l'enveloppe et venant en appui sur les cales longitudinales, ces clavettes ne gêneront pas l'ejection radiale des mines.The joining in rotation of the envelope with all the mines and the holding means is carried out in a known manner not shown, for example by keys integral with the envelope and coming to bear on the longitudinal wedges, these keys will not interfere not the radial ejection of mines.

Les moyens de confinement sont constitués ici par un étui 8, à l'intérieur duquel est disposée la charge détonante 4.The confinement means here consist of a case 8, inside which the detonating charge 4 is placed.

L'étui est réalisé en matière plastique du type polyéthylène.The case is made of plastic material of the polyethylene type.

Les mines sont maintenues par les moyens de maintien en contact avec l'étui au niveau d'une surface de contact 6 cylindrique. En coupe radiale, la médiatrice de la trace de cette surface de contact qui est donc un arc de cercle est la normale au milieu de cet arc et présente une direction radiale.The mines are maintained by the means for maintaining contact with the case at a cylindrical contact surface 6. In radial section, the perpendicular bisector of this contact surface which is therefore an arc of a circle is the normal in the middle of this arc and has a radial direction.

Les trois cordeaux de découpe 10 sont solidaires des cales longitudinales comme dans la variante précédente, ils sont également disposés de façon à découper les bandes cylindriques 11.The three cutting cords 10 are integral with the longitudinal shims as in the previous variant, they are also arranged so as to cut the cylindrical strips 11.

Ils sont régulièrement répartis angulairement, et de telle façon que la direction radiale du vecteur passant par chaque cordeau soit bissectrice de l'angle formé par les deux médiatrices 7 relatives aux mines adjacentes audit cordeau.They are regularly distributed angularly, and in such a way that the radial direction of the vector passing through each cord is bisecting the angle formed by the two perpendicular bisectors 7 relating to the mines adjacent to said cord.

On assure ainsi une dispersion radiale homogène des mines.This ensures a uniform radial dispersion of the mines.

Les mines étant maintenues en contact avec les moyens de confinement constitués par l'étui 8, la détonation de la charge 4 provoquera la dipersion des mines dans les directions radiales matérialisées par les médiatrices 7.The mines being kept in contact with the confinement means constituted by the case 8, the detonation of the charge 4 will cause the mines to dip in the radial directions materialized by the perpendicular bisectors 7.

Il est possible évidemment d'adapter l'invention à tout autre type de dispersion radiale de conteneurs.It is obviously possible to adapt the invention to any other type of radial dispersion of containers.

Il est possible ainsi de prévoir un vecteur dans lequel chaque groupe de conteneurs comporte plus de trois éléments, la forme de l'étui ainsi que des moyens de maintien sera alors adaptée en conséquence, et on choisira également la charge détonante en fonction de la masse à disperser et de la vitesse d'éjection souhaitée.It is thus possible to provide a vector in which each group of containers comprises more than three elements, the shape of the case as well as of the holding means will then be adapted accordingly, and the detonating charge will also be chosen as a function of the mass. to disperse and the desired ejection speed.

Il est possible également d'adapter l'invention à des projectiles dont la vitesse de rotation est plus importante, il suffira, pour éviter que l'inertie centrifuge écarte les conteneurs des moyens de confinement avant détonation de la charge explosive, de prévoir, en complément de la bande cylindrique 11, des moyens de maintien cisaillables qui assurent la cohésion de l'ensemble des conteneurs après découpe de l'enveloppe 3.It is also possible to adapt the invention to projectiles whose rotational speed is greater, it will suffice, to prevent the centrifugal inertia spreading the containers from the confinement means before detonation of the explosive charge, to provide, in band complement cylindrical 11, shearable holding means which ensure the cohesion of all the containers after cutting of the envelope 3.

On pourra par exemple dans le cas du mode de réalisation représenté Figure 1, prévoir des goupilles cisaillables disposées dans des logements réalisés sur les entailles 16 de façon à empêcher toute translation radiale des mines relativement aux entretoises 12 correspondantes.We can for example in the case of the embodiment shown in Figure 1, provide shear pins arranged in housings formed on the notches 16 so as to prevent any radial translation of the mines relative to the corresponding spacers 12.
