Description
Le domaine technique de l'invention est celui des charges formées, c'est à dire des charges comportant un chargement explosif disposé dans une enveloppe et un revêtement appliqué sur le chargement.The technical field of the invention is that of formed charges, that is to say charges comprising an explosive charge placed in a casing and a coating applied to the charge.
De telles charges formées sont bien connues. Le brevet
Les charges formées sont généralement conçues pour être mises en place dans une enveloppe de géométrie bien définie. Le plus souvent le chargement explosif est coulé à l'intérieur de l'enveloppe et le revêtement est collé sur une face avant évidée du chargement explosif.The formed loads are generally designed to be placed in an envelope of well-defined geometry. Most often the explosive charge is poured inside the casing and the coating is glued to a hollowed out front face of the explosive charge.
Le brevet
Une telle charge explosive étant montée dans une enveloppe avec un jeu radial, il se pose à la fois le problème de la solidarisation du chargement explosif et de l'enveloppe et celui du centrage de ce chargement.Since such an explosive charge is mounted in a casing with radial play, there is both the problem of securing the explosive charge and the casing and that of the centering of this charge.
Pour résoudre ces problèmes, le brevet
Une telle solution présente l'avantage de permettre une solidarisation simple et fiable de l'enveloppe et du chargement tout en autorisant une adaptation à une enveloppe ayant un diamètre interne différent.Such a solution has the advantage of allowing a simple and reliable joining of the envelope and the load while allowing adaptation to an envelope having a different internal diameter.
Elle présente cependant l'inconvénient d'imposer de multiples serrages suivant des directions radiales ce qui peut être difficile à réaliser (surtout pour des diamètres de chargement explosif réduits - par exemple inférieurs à 155 mm) et nécessite le plus souvent la définition de moyens de serrage spécifiques. Par ailleurs l'outil de serrage peut interférer avec le revêtement et le dégrader. Il est donc difficile d'assurer le couple de serrage nécessaire pour chaque vis.However, it has the drawback of imposing multiple tightening in radial directions which can be difficult to achieve (especially for reduced explosive charge diameters - for example less than 155 mm) and most often requires the definition of means of specific tightening. Furthermore, the tightening tool can interfere with the coating and degrade it. It is therefore difficult to ensure the necessary tightening torque for each screw.
C'est le but de l'invention que de proposer une charge formée ne présentant pas de tels inconvénients.It is the object of the invention to provide a shaped filler not exhibiting such drawbacks.
Ainsi la charge formée selon l'invention comporte des moyens de solidarisation de l'enveloppe et du chargement explosif portant le revêtement qui sont simples et fiables et qui permettent de faciliter l'opération de montage.Thus the charge formed according to the invention comprises means for securing the casing and the explosive charge carrying the coating which are simple and reliable and which make it possible to facilitate the assembly operation.
Ainsi l'invention a pour objet une charge formée comprenant un chargement explosif disposé dans une enveloppe, un revêtement appliqué sur le chargement, et des moyens assurant la solidarisation de l'enveloppe et du chargement portant le revêtement, moyens de solidarisation comprenant une bague présentant une surface de butée pour le revêtement, charge formée comprenant au moins deux cales couvrant chacune un secteur angulaire, cales se déplaçant radialement par rapport à la bague par l'action d'un moyen de serrage, pour venir s'appliquer contre une surface d'appui interne de l'enveloppe, le moyen de serrage comprenant au moins une vis pour chaque cale, vis coopérant avec un taraudage aménagé dans la bague et dont l'extrémité pousse la cale lors du vissage de la vis, charge formée caractérisée en ce que :
- lesdites cales sont positionnées axialement par rapport à la bague par au moins un axe radial qui est engagé dans un perçage radial de la bague et qui se loge dans un trou radial desdites cales, lesdites cales pouvant coulisser sur l'axe,
- le taraudage de la ou des vis de serrage ayant par ailleurs son axe parallèle à l'axe de l'enveloppe, la vis comportant une extrémité conique coopérant avec un alésage conique desdites cales, un déplacement axial de la vis lors de son vissage conduisant à un déplacement radial desdites cales.
- said wedges are positioned axially relative to the ring by at least one radial axis which is engaged in a radial bore of the ring and which is housed in a radial hole of said wedges, said wedges being able to slide on the axis,
- the tapping of the tightening screw (s) furthermore having its axis parallel to the axis of the casing, the screw comprising a conical end cooperating with a conical bore of said shims, an axial displacement of the screw during its screwing leading to a radial displacement of said wedges.
Selon un mode de réalisation, la charge comporte, pour chaque cale, un axe de positionnement disposé au niveau d'un plan médian de la cale et deux vis de serrage disposées de façon symétrique de part et d'autre de l'axe de positionnement.According to one embodiment, the load comprises, for each wedge, a positioning axis arranged at a median plane of the wedge and two clamping screws arranged symmetrically on either side of the positioning axis. .
Chaque cale pourra avantageusement comporter un profil externe conique destiné à coopérer avec une surface interne de l'enveloppe formant un appui conique pour assurer le maintien axial du chargement explosif par rapport à l'enveloppe.Each wedge may advantageously include a conical external profile intended to cooperate with an internal surface of the casing forming a conical support to ensure the axial retention of the explosive charge relative to the casing.
La bague pourra comporter un profil cylindrique externe assurant le guidage de la bague par rapport à l'enveloppe.The ring may include an external cylindrical profile ensuring the guidance of the ring relative to the casing.
La bague pourra par ailleurs comporter une portée cylindrique interne entourant un rebord externe du revêtement.The ring may also include an internal cylindrical surface surrounding an external rim of the coating.
La charge pourra comporter une rondelle ressort interposée entre le revêtement et la surface de butée de la bague.The load may include a spring washer interposed between the coating and the abutment surface of the ring.
Selon un mode particulier de réalisation, la charge pourra comporter quatre cales régulièrement réparties angulairement.According to a particular embodiment, the load may include four wedges regularly distributed angularly.
Les cales pourront ne pas couvrir tout le profil externe de la bague et être séparées par des rainures.The shims may not cover the entire external profile of the ring and be separated by grooves.
La charge pourra comporter un espace annulaire entre le chargement explosif et l'enveloppe, espace rempli d'un matériau compressible.The charge may include an annular space between the explosive charge and the envelope, a space filled with a compressible material.
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 :

En se reportant aux
La partie arrière de l'enveloppe 3 porte un couvercle de fermeture 21 qui reçoit des moyens d'amorçage, par exemple un détonateur 22 et un relais 23. Ces moyens ne font pas partie de l'invention et sont donc représentés de façon très schématique. On a figuré également à la base du chargement explosif 2 un écran conformateur d'onde de détonation 14.The rear part of the
Cette tête militaire 1 comprend également des moyens assurant la solidarisation de l'enveloppe 3 et du chargement 2 portant le revêtement 4. Ces moyens de solidarisation comprennent une bague 5 présentant une surface de butée 5a pour le revêtement et des cales 6 qui couvrent chacune un secteur angulaire. Il y a ici quatre cales 6 régulièrement réparties angulairement (voir la
Comme décrit par le brevet
Plus particulièrement dans le mode de réalisation qui est décrit ici, chaque cale 6 comporte un profil externe conique 6a qui est destiné à coopérer avec une surface interne 3a de l'enveloppe 3 qui forme un appui conique (voir la
Cette concordance de formes coniques permet d'assurer de façon fiable un maintien axial du chargement explosif 2 par rapport à l'enveloppe 3.This concordance of conical shapes makes it possible to reliably ensure axial retention of the
Bien entendu, et comme décrit par le brevet
Comme on le voit à la
Conformément à ce mode de réalisation, il y a un seul axe de positionnement 8 sur chaque cale 6, axe qui est disposé au niveau d'un plan médian de la cale 6 (voir la
L'axe 8 pourra comporter une partie arrière filetée qui sera engagée dans un taraudage de la bague 5 et une partie avant lisse qui recevra la cale 6.The
Le moyen de serrage de chaque cale 6 comprend au moins une vis 11 pour chaque cale, ici deux vis 11 disposées de façon symétrique de part et d'autre de l'axe de positionnement 8 (voir la
Conformément à l'invention, le taraudage 12 des vis de serrage 11 a son axe parallèle à l'axe 7 de l'enveloppe 3 et la vis 11 comporte une extrémité conique 11a qui coopère avec un alésage conique 6b de la cale 6 (voir la
Ainsi lorsque la vis 11 tourne dans son taraudage 12, son extrémité 11a pousse la cale 6. Cette dernière étant liée axialement à la bague 5 par l'axe 8, ce déplacement axial de la vis conduit à un déplacement radial de la cale 6. Le profil externe conique 6a de la cale 6 vient en contact avec la surface interne conique 3a de l'enveloppe 3. La poursuite du serrage de la vis 11 conduit à un glissement relatif de la cale 6 le long du profil conique 3a de l'enveloppe. Il en résulte un enfoncement axial de la bague 5 portant les cales 6, qui conduit à une légère compression d'une rondelle ressort 13 qui est interposée entre le revêtement 4 et la surface de butée 5a de la bague 5. Ainsi le chargement explosif 2 et le revêtement 4 sont immobilisés par rapport à l'enveloppe 3 mais il reste au chargement explosif 2 une possibilité de déformation axiale par dilatation par la compression de la rondelle ressort 13.Thus when the
La bague 5 comporte un profil cylindrique externe 19 assurant le guidage de la bague 5 par rapport à l'enveloppe 3. Un joint d'étanchéité (non représenté) pourra être positionné dans une gorge 24 au niveau du profil cylindrique externe 19.The
Par ailleurs la bague 5 comporte une portée cylindrique interne 15 qui entoure un rebord externe du revêtement 4. Ainsi, lors du montage, la bague 5 est positionnée de façon précise vis-à-vis du revêtement 4 et du chargement explosif 2. On remarque également sur les
La bague 5 comporte enfin une gorge périphérique 18 (
La bague 5 portant les quatre cales 6 peut donc être introduite sans difficultés à l'intérieur de l'enveloppe 3.The
Une fois le chargement portant la bague équipée des cales mis en place dans l'enveloppe, le serrage des vis 11 permettra la solidarisation du chargement 2 avec l'enveloppe 3 par le coulissement radial des cales 6.Once the load carrying the ring fitted with the wedges in place in the casing, tightening the
