The present invention relates to a container-disperser for chaff constituted by metal strips or by metallized strips, the container-disperser comprising two end plates (130, 140) which are generally parallel and interconnected by spacers (150, 155) suitable for trapping strips of chaff so as to temporarily retain at least a portion of the chaff when the container is ejected from a case, thereby dispersing the chaff in stages.

Description

La présente invention concerne les leurres électromagnétiques.The present invention relates to electromagnetic decoys.

La présente invention concerne plus précisément un conteneur-disperseur de paillettes métalliques ou métallisées formant écran réflecteur aux ondes électromagnétiques et constituant des leurres pour la déception de systèmes d'arme équipés d'un guidage à détecteur électromagnétique actif.The present invention relates more precisely to a container-disperser of metallic or metallized flakes forming a screen reflecting electromagnetic waves and constituting decoys for the deception of weapon systems equipped with a guide with active electromagnetic detector.

Le terme "paillettes" doit être compris dans un sens large; il recouvre les aiguilles, rubans et/ou particules métalliques ou métallisées, en particulier les fibres de verre métallisées, de longueur choisie, souvent dénommées "chaffs" connus de l'homme de l'art et généralement utilisés pour la séduction et le détournement des systèmes de guidage d'arme.The term "glitter" should be understood in a broad sense; it covers the needles, ribbons and / or metallic or metallized particles, in particular metallized glass fibers, of chosen length, often called "chaffs" known to those skilled in the art and generally used for the seduction and diversion of weapon guidance systems.

On a illustré sur la figure 1a annexée, en vue éclatée, et sur la figure 1b annexée, en vue assemblée, la structure d'un conteneur classique de paillettes.Is illustrated in Figure 1a attached, in exploded view, and in Figure 1b attached, in assembled view, the structure of a conventional container of glitter.

Le conteneur classique 10 illustré sur les figures annexées comprend une embase 20 et deux coquilles amovibles 30, 40 qui définissent en combinaison un boîtier fermé cylindrique apte à recevoir un bloc cylindrique 50 de paillettes. Le bloc 50 est schématiquement illustré en traits interrompus sur la figure 1a. L'embase 20 est formée d'un disque. Chaque coquille 30, 40, comprend une paroi hémicylindrique 32, 42 coaxiale au disque 20 et une toile hémicirculaire 34, 44 solidaire de la paroi 32, 42 et parallèle à l'embase 20.The conventional container 10 illustrated in the appended figures comprises a base 20 and two removable shells 30, 40 which in combination define a closed cylindrical housing capable of receiving a cylindrical block 50 of glitter. Block 50 is schematically illustrated in broken lines in FIG. 1a. The base 20 is formed of a disc. Each shell 30, 40 comprises a semi-cylindrical wall 32, 42 coaxial with the disc 20 and a semi-circular fabric 34, 44 secured to the wall 32, 42 and parallel to the base 20.

Le conteneur 10 est placé généralement dans la douille d'une cartouche. Les coquilles 30, 40 sont séparées de l'embase 20, pour libérer le bloc 50 de paillettes, lorsque le conteneur est éjecté hors de la douille.The container 10 is generally placed in the socket of a cartridge. The shells 30, 40 are separated from the base 20, to release the block 50 of glitter, when the container is ejected from the sleeve.

Le document EP-A-0029078 décrit un autre conteneur-disperseur de leurres électromagnétiques comprenant une coquille principale et deux coquilles auxiliaires. La coquille principale comprend une paroi plane circulaire munie respectivement de part et d'autre de deux parois hémicylindriques diamétralement opposées. Les coquilles auxiliaires comprennent chacune une paroi hémicylindrique et un couvercle en forme de paroi plane et circulaire.Document EP-A-0029078 describes another container-disperser for electromagnetic decoys comprising a main shell and two auxiliary shells. The main shell comprises a circular flat wall provided respectively on either side with two diametrically opposite semi-cylindrical walls. The auxiliary shells each comprise a semi-cylindrical wall and a cover in the form of a flat and circular wall.

Le document DE-A-3327043 décrit un autre conteneur-disperseur de leurres électromagnétiques qui selon le préambule de la revendication 1 comprend des flasques reliés par une entretoise centrale. Le document DE-A-3327043 précise que pour tenter de contrôler une dispersion échelonnée des leurres, les flasques sont revêtus sur leur surface inférieure, par flocage, d'un matériau synthétique apte à retenir les extrémités des leurres.Document DE-A-3327043 describes another container-disperser for electromagnetic decoys which, according to the preamble of claim 1, comprises flanges connected by a central spacer. Document DE-A-3327043 specifies that in an attempt to control a staggered dispersion of the lures, the flanges are coated on their lower surface, by flocking, with a synthetic material capable of retaining the ends of the lures.

Les conteneurs connus ont déjà rendu de grands services. Cependant, la Demanderesse a constaté que ces conteneurs présentent fréquemment l'inconvénient de libérer des paquets de paillettes agglomérés, totalement inefficaces pour la déception des systèmes de guidage d'arme, au lieu de disperser les paillettes.Known containers have already done great service. However, the Applicant has found that these containers frequently have the drawback of releasing bundles of agglomerated flakes, which are totally ineffective for the disappointment of weapon guidance systems, instead of dispersing the flakes.

La présente invention a pour but d'éliminer cet inconvénient.The object of the present invention is to eliminate this drawback.

A cet effet la présente invention propose un conteneur disperseur de paillettes métalliques ou métallisées formant écran réflecteur aux ondes électromagnétiques et constituant des leurres, du type comprenant un corps composé de deux flasques généralement parallèles reliés rigidement par au moins une entretoise, caractérisé par le fait que:

  • ― l'un au moins des flasques possède au moins un évidement périphérique,
  • ― que le conteneur comprend en outre au moins une coquille amovible telle que les entretoises et la ou les coquille(s) forme(nt) en combinaison une enveloppe continue entre les deux flasques, la ou les coquille(s) possédant une toile complémentaire de l'évidement de sorte que les entretoises forment piège à l'égard des paillettes, afin de retenir temporairement au moins une partie de celles-ci lorsque le conteneur est éjecté hors d'une douille et contrôler une dispersion échelonnée des paillettes.
To this end, the present invention provides a container for dispersing metallic or metallized flakes forming a screen reflecting electromagnetic waves and constituting decoys, of the type comprising a body composed of two generally parallel flanges rigidly connected by at least one spacer, characterized in that :
  • At least one of the flanges has at least one peripheral recess,
  • - that the container also comprises at least one removable shell such as the spacers and the shell (s) form (s) in combination a continuous envelope between the two flanges, the shell (s) having a complementary fabric of the recess so that the spacers form a trap with respect to the flakes, in order to temporarily retain at least part of these when the container is ejected from a socket and to control a staggered dispersion of the flakes.

D'autres caractéristiques, buts et avantages de la présente invention apparaîtront à la lecture de la description détaillée qui va suivre, et en regard des dessins annexés, donnés à titre d'exemples non limitatifs, sur lesquels, les figures 1a et 1b qui illustrent l'état de la technique ayant déjà été décrites:

  • ― la figure 2 représente une vue schématique, en perspective, et en position séparée des coquilles, d'un conteneur conforme à la présente invention,
  • ― la figure 3 représente une vue schématique en perspective du même conteneur, en position assemblée.
  • ― la figure 4 représente une vue schématique partielle en perspective éclatée du même conteneur et illustre plus particulièrement la structure du corps de celui-ci, et
  • ― la figure 5 représente une vue en coupe longitudinale du même conteneur selon un plan de coupe référencé V-V sur la figure 4.
Other characteristics, aims and advantages of the present invention will appear on reading the detailed description which follows, and with reference to the appended drawings, given by way of nonlimiting examples, in which FIGS. 1a and 1b which illustrate the state of the art having already been described:
  • FIG. 2 represents a schematic perspective view, in a position separated from the shells, of a container according to the present invention,

Le conteneur 100 illustré sur les figures 2 à 5 comprend un corps 120 et deux coquilles amovibles 160, 180.The container 100 illustrated in FIGS. 2 to 5 comprises a body 120 and two removable shells 160, 180.

Le corps 120 et les coquilles 160, 180 forment en combinaison un boîtier cylindrique fermé centré sur un axe 100. Ce dernier constitue un axe de symétrie du conteneur.The body 120 and the shells 160, 180 form in combination a closed cylindrical housing centered on an axis 100. The latter constitutes an axis of symmetry of the container.

Le corps 100 comprend deux flasques parallèles 130, 140 reliés par deux entretoises 150, 155.The body 100 comprises two parallel flanges 130, 140 connected by two spacers 150, 155.

Le premier flasque 130 est formé d'un disque transversal à l'axe 102 et centré sur celui-ci.The first flange 130 is formed of a disc transverse to the axis 102 and centered on it.

Le second flasque 140 est constitué d'un voile également transversal à l'axe 102 et centré sur celui-ci. Le voile est délimité par une enveloppe en forme de disque pourvu de deux évidements 141, 144. Le rayon externe du flasque 140 égale le rayon externe du flasque 130. Les évidements 141, 144 débouchent sur la périphérie du flasque 140. Ils sont diamètralement opposés par rapport à l'axe 102. Ils ont la forme de secteurs circulaires centrés sur l'axe 102. L'évidement 141 est limité par les rayons 142, 143 présentant une ouverture angulaire α. Le second évidement 144 est limité par les rayons 145, 146 présentant de préférence la même ouverture angulaire α. Les rayons 142, 143 et 145, 146, et donc les évidements 141, 144, possèdent un plan de symétrie, passant par l'axe 102 et orthogonal au plan de coupe de la figure 5.The second flange 140 consists of a veil also transverse to the axis 102 and centered on it. The veil is delimited by a disc-shaped envelope provided with two recesses 141, 144. The external radius of the flange 140 equals the external radius of the flange 130. The recesses 141, 144 open onto the periphery of the flange 140. They are diametrically opposite with respect to the axis 102. They have the shape of circular sectors centered on the axis 102. The recess 141 is limited by the spokes 142, 143 having an angular opening α. The second recess 144 is limited by the spokes 145, 146 preferably having the same angular opening α. The spokes 142, 143 and 145, 146, and therefore the recesses 141, 144, have a plane of symmetry, passing through the axis 102 and orthogonal to the section plane of FIG. 5.

De préférence l'ouverture angulaire α est de l'ordre de 90°.Preferably the angular opening α is of the order of 90 °.

Cependant, les évidements 141, 144 ne s'étendent pas jusqu'à l'axe 102 pour ne pas diviser le flasque 140 en deux éléments séparés, mais maintenir le flasque 140 sous forme unitaire.However, the recesses 141, 144 do not extend to the axis 102 so as not to divide the flange 140 into two separate elements, but to keep the flange 140 in unitary form.

La zone radialement la plus interne des évidements 141, 144 est donc délimitée par des génératrices 147, 148 transversales au plan de symétrie précité des évidements.The radially innermost zone of the recesses 141, 144 is therefore delimited by generatrices 147, 148 transverse to the aforementioned plane of symmetry of the recesses.

Les entretoises 150, 155 sont diamètralement opposées par rapport à l'axe 102. Elles sont formées de secteurs de cylindre centrés sur l'axe 102. Les entretoises 150, 155 possèdent un rayon de courbure égal au rayon extérieur des flasques 130, 140. Les entretoises 150, 155 présentent une ouverture angulaire β complémentaire de celle des évidements 141, 144. En d'autres termes, l'entretoise 155 possède une ouverture angulaire β égale à l'angle délimité par les rayons 143, 146. La seconde entretoise 150 possède une ouverture angulaire β égale à l'angle délimité par les rayons 142, 145. Les entretoises 150, 155 s'étendent entre le flasque 130 et le flasque 140. Cependant elles se prolongent au delà du flasque 140 sous forme de nervures d'allure annulaire centrées sur l'axe 102, référencées 151, 156.The spacers 150, 155 are diametrically opposite with respect to the axis 102. They are formed by cylinder sectors centered on the axis 102. The spacers 150, 155 have a radius of curvature equal to the outside radius of the flanges 130, 140. The spacers 150, 155 have an angular opening β complementary to that of the recesses 141, 144. In other words, the spacer 155 has an angular opening β equal to the angle delimited by the spokes 143, 146. The second spacer 150 has an angular opening β equal to the angle delimited by the spokes 142, 145. The spacers 150, 155 extend between the flange 130 and the flange 140. However, they extend beyond the flange 140 in the form of ribs d ring shape centered on the axis 102, referenced 151, 156.

Les coquilles 160, 180 sont formées chacun d'une paroi 161, 181 et d'une toile 162, 182. Les parois 161, 181 sont formées de secteurs de cylindre centrés sur l'axe 102 ayant le même rayon et la même longueur que les entretoises 150, 155. Les parois 161, 181 présentent une ouverture angulaire complémentaire des entretoises 150, 155, soit égale à l'angle α. Les toiles 162, 182 sont délimitées par des secteurs circulaires généralement plans présentant la même ouverture angulaire α; le contour des toiles 162, 182 est complémentaire des évidements 141, 144. Les toiles 162, 182 sont transversales à l'axe 102. Les parois 161, 181 se raccordent à la périphérie des toiles 162, 182. Cependant elles se prolongent au delà des toiles 162, 182 sous forme de nervures centrées sur l'axe 102, référencées 163, 183.The shells 160, 180 are each formed by a wall 161, 181 and a fabric 162, 182. The walls 161, 181 are formed by cylinder sectors centered on the axis 102 having the same radius and the same length than the spacers 150, 155. The walls 161, 181 have an angular opening complementary to the spacers 150, 155, is equal to the angle α. The fabrics 162, 182 are delimited by generally flat circular sectors having the same angular opening α; the outline of the cloths 162, 182 is complementary to the recesses 141, 144. The cloths 162, 182 are transverse to the axis 102. The walls 161, 181 are connected to the periphery of the cloths 162, 182. However they extend beyond fabrics 162, 182 in the form of ribs centered on the axis 102, referenced 163, 183.

En position assemblée, les nervures 151, 156, 163, 183 forment un anneau continu centré sur l'axe 102.In the assembled position, the ribs 151, 156, 163, 183 form a continuous ring centered on the axis 102.

De préférence, le corps 100 est constitué de deux éléments 103, 104, comme illustré sur la figure 4.Preferably, the body 100 consists of two elements 103, 104, as illustrated in FIG. 4.

L'élément 103 est formé par le flasque 130 et une colonne 132 solidaire de la face interne 135 du flasque 130 et centrée sur l'axe 102. La colonne 132 est munie d'un canal central 134.The element 103 is formed by the flange 130 and a column 132 secured to the internal face 135 of the flange 130 and centered on the axis 102. The column 132 is provided with a central channel 134.

Le second élément 104 est formé par le flasque 140, les deux entretoises 150, 155 et une canne cylindrique 157 centrée sur l'axe 102 solidaire de la face interne du flasque 140 entre les deux entretoises 150, 155. La canne 157 est adaptée pour recevoir la colonne 132.The second element 104 is formed by the flange 140, the two spacers 150, 155 and a cylindrical rod 157 centered on the axis 102 integral with the internal face of the flange 140 between the two spacers 150, 155. The rod 157 is suitable for receive column 132.

De préférence le flasque 130 est muni sur sa surface interne et sur sa périphérie d'une rainure annulaire 136 centrée sur l'axe 102. Cette rainure possède un rayon de courbure interne égal au rayon de courbure interne des entretoises 150, 155 et des parois 161, 181, pour recevoir l'extrémité de celle-ci opposée au flasque 140 et aux toiles 162, 182.Preferably the flange 130 is provided on its internal surface and on its periphery with an annular groove 136 centered on the axis 102. This groove has an internal radius of curvature equal to the radius of internal curvature of the spacers 150, 155 and of the walls 161, 181, to receive the end of the latter opposite the flange 140 and the fabrics 162, 182.

Plus précisément, de façon avantageuse, cette rainure 136 est délimitée par une surface 137, transversale à la surface interne 135 du flasque 130, qui n'est pas parallèle à l'axe 102, mais tronconique de révolution autour de l'axe 102 en convergeant vers cet axe 102 en éloignement de la surface 135. De plus, les coquilles 160,180 sont pourvues sur la surface interne des parois 161,181, à l'opposé des toiles 162,182 de nervures 184 complémentaires de la rainure 136 précitée. Grâce à l'engagement ainsi défini entre la rainure 136 et les nervures 184, les coquilles 160, 180 ne peuvent se déplacer axialement par rapport au corps 120 qu'après éjection du conteneur-disperseur hors d'une douille de cartouche.More precisely, advantageously, this groove 136 is delimited by a surface 137, transverse to the internal surface 135 of the flange 130, which is not parallel to the axis 102, but frustoconical of revolution around the axis 102 in converging on this axis 102 in away from the surface 135. In addition, the shells 160,180 are provided on the internal surface of the walls 161,181, opposite the webs 162,182 with ribs 184 complementary to the above-mentioned groove 136. Thanks to the engagement thus defined between the groove 136 and the ribs 184, the shells 160, 180 can only move axially relative to the body 120 after ejection of the container-disperser out of a cartridge case.

Pour assembler le corps 100, il suffit de placer la colonne 132 dans la canne 157. Lorsque les coquilles 160, 180 sont placées sur le corps 100, comme illustré sur la figure 3, elles forment avec celui-ci un boîtier cylindrique fermé apte à contenir un paquet de paillettes. Celles-ci sont de préférence placées parallèlement à l'axe 102.To assemble the body 100, it suffices to place the column 132 in the rod 157. When the shells 160, 180 are placed on the body 100, as illustrated in FIG. 3, they form therewith a closed cylindrical housing suitable for contain a packet of glitter. These are preferably placed parallel to the axis 102.

Le cas échéant il peut être ménagé plusieurs découpes dans le paquet de paillettes, transversalement à l'axe 102, à travers le corps 100 et/ou les coquilles 160, 180 pour réaliser des paillettes de différentes longueurs. Pour diversifier la longueur des paillettes, les flasques 130, 140 sont de préférence tronconiques. Ces dispositions sont déjà décrites dans la demande de brevet FR-A-2521716 au nom de la Demanderesse et ne seront donc pas décrites plus en détail par la suite. On notera cependant que de préférence lorsqu'il est prévu des paillettes couvrant toute la longueur des entretoises 150, 155, ces paillettes les plus longues, non coupées, sont placées en regard des coquilles 160, 180 pour être éjectées en premier, lors de la séparation des coquilles 160, 180.If necessary, several cuts can be made in the glitter pack, transverse to the axis 102, through the body 100 and / or the shells 160, 180 to make glitter of different lengths. To diversify the length of the flakes, the flanges 130, 140 are preferably frustoconical. These arrangements are already described in patent application FR-A-2521716 in the name of the Applicant and will therefore not be described in more detail below. Note however that preferably when there is provided flakes covering the entire length of the spacers 150, 155, these longer flakes, uncut, are placed opposite the shells 160, 180 to be ejected first, during the separation of the shells 160, 180.

Le conteneur représenté sur les figures 2 à 5 annexées peut être placé dans une douille de cartouche lance-leurre telle que définie dans les demandes de brevet FR-A-2521716 et FR-A-2436363 ou une cartouche équivalente.The container shown in FIGS. 2 to 5 appended can be placed in a decoy launch cartridge socket as defined in patent applications FR-A-2521716 and FR-A-2436363 or an equivalent cartridge.

Lorsque le conteneur est éjecté hors de la douille, les nervures 163, 183 prévues sur les coquilles 160, 180 offrent une "prise au vent" qui facilite la séparation de ces dernières.When the container is ejected from the sleeve, the ribs 163, 183 provided on the shells 160, 180 provide a "windward" which facilitates the separation of the latter.

Les paillettes placées en regard des coquilles 160, 180 sont dispersées en premier. Les paillettes placées en regard des entretoises 150, 155 sont dispersées ultérieurement sur la trajectoire du conteneur.The flakes placed opposite the shells 160, 180 are dispersed first. The flakes placed opposite the spacers 150, 155 are dispersed later on the trajectory of the container.

Le flasque 130 peut contenir une charge pyrotechnique de dépotement, tandis que la colonne 132 et la canne 157 peuvent contenir des relais et retard pyrotechniques, comme enseignés par les documents FR-A-2 B521716 et FR-A-2436363, pour diffuser successivement une pluralité de charges élémentaires de leurres placées dans des conteneurs respectifs empilés dans une cartouche commune.The flange 130 may contain a pyrotechnic charge for the deposition, while the column 132 and the rod 157 may contain pyrotechnic relays and delays, as taught by documents FR-A-2 B521716 and FR-A-2436363, for successively diffusing a plurality of elementary charges of lures placed in respective containers stacked in a common cartridge.
