Description

L'invention concerne une tête militaire utilisable notamment dans les obus, roquettes et missiles, pour agresser les chars de bataille, que leur blindage soit simple, feuilleté, . composite ou actif, c'est-à-dire explosant lorsqu'une certaine quantité d'énergie lui est fournie par un projectile.The invention relates to a military head usable in particular in shells, rockets and missiles, for attacking battle tanks, whether their armor is simple, laminated,. composite or active, i.e. exploding when a certain amount of energy is supplied to it by a projectile.

L'emploi des blindages actifs en particulier, a engendré un nouveau concept de tête militaire à charges formées montées en tandem- L'initiation de la première charge entraîne, en séquence, celle de la deuxième avec toutefois un retard de fonctionnement entre les deux.The use of active armor in particular, has generated a new concept of military head with shaped charges mounted in tandem. The initiation of the first charge leads, in sequence, to that of the second with, however, an operating delay between the two.

Ce retard est nécessaire pour ne faire fonctionner la deuxième charge qu'après destruction de la protection active et pour éviter le rattrapage du premier jet par le second, le retard optimal variant selon, d'une part la nature et l'épaisseur des plaques constitutives du blindage actif et d'autre part l'angle d'incidence du projectile sur la cible.This delay is necessary in order to operate the second charge only after destruction of the active protection and to avoid the catching of the first jet by the second, the optimal delay varying according, on the one hand, to the nature and the thickness of the constituent plates active armor and on the other hand the angle of incidence of the projectile on the target.

Une augmentation du retard peut avoir de nombreuses conséquences qui sont autant d'inconvénients, à savoir, l'augmentation de la distance d'action optimale de le deuxième charge explosive, la diminution de la vitesse du projectile et l'augmentation des interactions entre les deux chargesAn increase in the delay can have many consequences which are as many disadvantages, namely, the increase of the optimal distance of action of the second explosive charge, the decrease in the speed of the projectile and the increase in the interactions between the two charges

On connait par le brevet FR2552870, une tête militaire à charges formées montées en tandem. Cette arme comporte une charge plate A, disposée à la partie avant du projectile et une charge creuse B de même calibre disposée dans l'axe et à l'arrière de la charge plate. La charge-creuse B est initiée après la charge A avec un retard prédéterminé.We know from patent FR2552870, a military head with shaped charges mounted in tandem. This weapon comprises a flat charge A, placed at the front part of the projectile and a hollow charge B of the same caliber placed in the axis and at the rear of the flat charge. The hollow charge B is initiated after the charge A with a predetermined delay.

Une telle tête militaire s'applique à la perforation des blindages simples, feuilletés, composites ou actifs mais, dans ce dernier cas, provoque leur initiation.Such a military head applies to the perforation of simple, laminated, composite or active armor but, in the latter case, causes their initiation.

L'invention vise donc à pallier les inconvénients précités, en proposant une tête militaire à charges formées montées en tandem et fonctionnant en séquence, de telle manière que le charge de tête génère un jet capable de perforer un blindage actif sans t'initier, la deuxième charge formée pouvant alors être initiée après un temps très bref, ce court retard étant nécessaire pour éviter le rattrapage du jet engendré par le première charge par le jet de la deuxième charge, mais pouvant être réduit au minimum compte tenu de la non initiation du blindage actif.The invention therefore aims to overcome the aforementioned drawbacks, by proposing a military head with shaped charges mounted in tandem and operating in sequence, in such a way that the head charge generates a jet capable of perforating an active armor without initiating it, the second charge formed can then be initiated after a very short time, this short delay being necessary to avoid catching up of the jet generated by the first charge by the jet of the second charge, but which can be reduced to a minimum taking into account the non initiation of the active shielding.

La tête militaire, selon l'invention, comprend une charge formée avant et une charge formée arrière montées en tandem et fonctionnant en séquence, caractérisée en ce que la charge avant comporte un revêtement de révolution, dont le calibre est compris entre 25 et 70 % du calibre de là charge arrière, le rapport de la hauteur sur le calibre est compris entre 0,15 et 1,5, dont l'épaisseur moyenne se situe entre 1 et 5 % de son calibre et dont la masse volumique est comprise entre 500 et 4 000 kg/m3, de manière à créer un jet d'énergie cinétique inférieure à 200 kilojoules.The military head, according to the invention, comprises a front formed load and a rear formed load mounted in tandem and operating in sequence, characterized in that the front load comprises a coating of revolution, the caliber of which is between 25 and 70% of the caliber of the rear load, the ratio of the height to the caliber is between 0.15 and 1.5, whose average thickness is between 1 and 5% of its caliber and whose density is between 500 and 4,000 kg / m3, so as to create a kinetic energy jet of less than 200 kilojoules.

Selon une autre caractéristique, le revêtement de la charge avant est réalisé dans un des matériaux du groupe suivant : alliages d'aluminium ou de magnésium, verre, matériaux organiques.According to another characteristic, the front load is coated with one of the materials from the following group: aluminum or magnesium alloys, glass, organic materials.

Selon un réalisation particulière, la charge avant comporte un revêtement conique 5 en alliage d'aluminium d'angle au sommet sensiblement égal à 70°, dont le calibre avoisine 60 % de celui de la charge arrière et dont l'épaisseur moyenne est de l'ordre de 3 % de son calibre.According to a particular embodiment, the front load comprises a conical coating 5 of aluminum alloy with an apex angle substantially equal to 70 °, the caliber of which is around 60% of that of the rear load and whose average thickness is l 3% of its caliber.

Selon une autre variante, la charge avant comporte un revêtement en alliage d'aluminium, de forme ellipsoîdale, dont le rapport de la hauteur sur le calibre est égal à 1 et l'épaisseur moyenne de l'ordre de 3,5 % de son calibre.According to another variant, the front load comprises an aluminum alloy coating, of ellipsoidal shape, the ratio of the height to the caliber is equal to 1 and the average thickness of the order of 3.5% of its caliber.

Selon d'autres caractéristiques :

  • -l'explosif utilisé pour réaliser le chargement de la charge avant est un explosif à vitesse de détonation inférieure à 8 000 m/s pouvant être par exemple un explosif composite, du baratot ou du trinitrotoluène.
  • -le retard de fonctionnement entre la charge avant et la charge arrière se situe entre 100 et 300 microsecondes et plus précisément est égal à 150 microsecondes.
According to other characteristics:
  • -the explosive used to charge the front charge is an explosive with a detonation speed of less than 8000 m / s, which may for example be a composite explosive, baratot or trinitrotoluene.
  • the operating delay between the front load and the rear load is between 100 and 300 microseconds and more precisely is equal to 150 microseconds.

D'autres caractéristiques et avantages de l'invention apparaîtront à la lecture de la description détaillée d'un mode de réalisation particulier de l'invention faite en regard du dessin annexé représentant une coupe longitudinale d'une tête militaire selon l'invention.Other characteristics and advantages of the invention will appear on reading the detailed description of a particular embodiment of the invention made with reference to the appended drawing representing a longitudinal section of a military head according to the invention.

Cette tête militaire comprend une enveloppe 1 dans laquelle sont disposées deux charges explosives 2 et 3 respectivement appelées charge avant et charge arrière.This military head comprises an envelope 1 in which are placed two explosive charges 2 and 3 respectively called front charge and rear charge.

La charge avant 2 dont le calibre est compris entre 25 et 70 % du calibre de la charge arrière est constituée par une masse d'explosif 4 limitée vers l'avant par un revêtement métallique 5, et comportant à l'arrière un dispositif d'amorçage 6 non représenté en détail mais connu de l'homme de l'artThe front charge 2, the caliber of which is between 25 and 70% of the caliber of the rear charge, consists of an explosive mass 4 limited towards the front by a metallic coating 5, and comprising at the rear a device for priming 6 not shown in detail but known to those skilled in the art

Le revêtement 5 peut être conique, sphérique ou ellipsoïdal et plus généralement de révolution, mais ses caractéristiques géométriques doivent répondre aux conditions suivantes :

  • -dans le cas d'un revêtement conique, l'angle au sommet doit être compris entre 40 et 140° et son épaisseur moyenne doit se situer entre 1 et 5 % de son calibre.
The coating 5 can be conical, spherical or ellipsoidal and more generally of revolution, but its geometric characteristics must meet the following conditions:
  • -in the case of a conical coating, the angle at the top must be between 40 and 140 ° and its average thickness must be between 1 and 5% of its size.

Dans cet exemple particulier de réalisation, l'angle au sommet est de 70° et l'épaisseur est égale-à 3 % du calibre de la charge.

  • -dans le cas d'un revêtement de révolution, tel que sphérique ou ellipsoïdal, le rapport de sa hauteur h sur son diamètre doit être compris entre 0,15 et 1,5, les caractéristiques concernant son épaisseur étant identiques à celles données précédemment pour les revêtements de forme conique. Dans cet exemple particulier de réalisation, le rapport de sa hauteur sur son diamètre est égal à 1 et son épaisseur égale à 3,5 % du diamètre.
  • -le revêtement est en matériau de masse volumique comprise entre 500 et 4 000 kg/m3 tel que, dans cet exemple particulier, de l'alliage d'aluminium. Le matériau constituant le revêtement peut être également choisi parmi les matériaux suivants : alliage de magnésium, matériaux organiques tel du plexiglas ou des matériaux vitreux tels que du verre pyrex, de l'oxyde ou sulfure de bore ou un gel d'alumine.
  • -l'explosif 4 constituant cette charge doit être un explosif basse énergie dont la vitesse de détonation est inférieure de 8 000 m/s tel que par exemple du trinitrotoluène, du baratol, ou un explosif composite.
In this particular embodiment, the angle at the top is 70 ° and the thickness is equal to 3% of the caliber of the load.
  • -in the case of a coating of revolution, such as spherical or ellipsoidal, the ratio of its height h to its diameter must be between 0.15 and 1.5, the characteristics concerning its thickness being identical to those given above for tapered coatings. In this particular embodiment, the ratio of its height to its diameter is equal to 1 and its thickness equal to 3.5% of the diameter.
  • the coating is made of a material with a density of between 500 and 4,000 kg / m 3 such as, in this particular example, aluminum alloy. The material constituting the coating can also be chosen from the following materials: magnesium alloy, organic materials such as plexiglass or vitreous materials such as pyrex glass, boron oxide or sulfide or an alumina gel.
  • -the explosive 4 constituting this charge must be a low-energy explosive whose detonation speed is lower than 8000 m / s such as for example trinitrotoluene, baratol, or a composite explosive.

Les caractéristiques géométriques du revêtement ainsi que la nature de l'explosif constituant la charge avant doivent être choisies de telle manière que la vitesse du jet par rapport à la cible soit inférieure à 8 000 m/s et que son énergie cinétique soit inférieure à 200 kilojoules ; cette condition étant nécessaire pour que l'explosif constituant le blindage actif ne puisse être initié.The geometrical characteristics of the coating as well as the nature of the explosive constituting the front charge must be chosen in such a way that the speed of the jet relative to the target is less than 8000 m / s and that its kinetic energy is less than 200 kilojoules; this condition being necessary so that the explosive constituting the active armor cannot be initiated.

Le charge arrière est une charge creuse à hautes performances, comportant un revêtement conique 7 d'angle fermé et un explosif 8 pouvant être hautement énergétique.The rear charge is a high performance hollow charge, comprising a conical coating 7 with a closed angle and an explosive 8 which can be highly energetic.

Cette tête militaire comporte également un écran protecteur 9 dont la fonction est de protéger la charge arrière lorsque la charge avant détone. Un dispositif de sécurité et d'armement 10 est disposé à l'arrière de la charge 3 et transmet l'ordre d'initiation à la charge avant par l'intermédiaire d'un cordeau détonant 11 qui pourrait par exemple être remplacé par une ligne électrique reliée au dispositif d'amorçage 6.This military head also includes a protective screen 9 whose function is to protect the rear load when the front load detonates. A security and arming device 10 is disposed at the rear of the load 3 and transmits the initiation order to the front load via a detonating cord 11 which could, for example, be replaced by a line electric connected to the priming device 6.

La détection de la cible peut être réalisée par tout moyen connu de l'homme de l'art tel qu'une fusée de proche proximité ou par contact.The detection of the target can be carried out by any means known to those skilled in the art such as a near proximity rocket or by contact.

De même le retard de fonctionnement entre les charges avant et arrière peut être réalisé par exemple à l'aide d'un enroulement de cordeau détonant, d'un dispositif électronique ou d'un composant pyrotechnique à retard de 150 microsecondes.Similarly, the operating delay between the front and rear loads can be achieved for example using a detonating cord winding, an electronic device or a pyrotechnic component with a delay of 150 microseconds.

Un avantage particulier de cette invention réside dans son adaptation à perforer les blindages actifs tout en offrant une tête militaire allégée, la protection inter-charges 9 pouvant être réduite compte tenu du retard d'initiation très court entre les deux charges.A particular advantage of this invention lies in its adaptation to perforate active armor while offering a lighter military head, the inter-charge protection 9 can be reduced given the very short initiation delay between the two charges.

D'autre part, du fait de la non initiation de la protection active, l'efficacité de ce type de tête militaire n'est pas influencée par les caractéristiques du blindage actif, notamment les vitesses de projection des plaques et leurs dimensions latérales.On the other hand, due to the non-initiation of active protection, the effectiveness of this type of military head is not influenced by the characteristics of the active armor, in particular the projection speeds of the plates and their lateral dimensions.
