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, composite ou actif.The invention relates to a military head usable in particular in shells, rockets and missiles for attacking battle tanks, whether their armor is simple, composite or active.

L'apparition des nouveaux 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 (àT) entre les deux.The appearance of new armor, particularly active, has given rise to a new concept of military head with shaped charges mounted in tandem. The initiation of the first charge causes, in sequence, that of the second with, however, an operating delay (at T) between the two.

Ce retard est nécessaire:

  • - pour ne faire fonctionner la deuxième charge qu'après destruction de la protection active correspondant à la durée de la vie du blindage actif,
  • - pour éviter le rattrapage du premier jet par le second.
This delay is necessary:
  • - to operate the second load only after destruction of the active protection corresponding to the lifetime of the active shielding,
  • - to avoid the second jet catching up with the second.

Le retard AT optimal varie selon, d'une part la nature et l'épaisseur des plaques constitutives du blindage actif et d'autres part l'angle d'incidence du projectile sur la cible.The optimal delay AT varies according to, on the one hand the nature and the thickness of the plates constituting the active shielding and on the other hand the angle of incidence of the projectile on the target.

Une augmentation de 8T peut avoir comme conséquences, qui sont autant d'inconvénients:

  • - l'augmentation de la distance d'action optimale de la deuxième charge explosive,
  • - la diminution de la vitesse du projectile,
  • - l'augmentation des interactions entre les deux charges.
An increase of 8 T can have consequences, which are all disadvantages:
  • - increasing the optimal distance of action of the second explosive charge,
  • - the reduction in the speed of the projectile,
  • - increased interactions between the two charges.

Le brevet FR-A 2 552 870 qui constitue l'état de la technique le plus proche de l'invention, décrit un projectile polyvalent, dont l'éfficacité contre les blindages actifs n'a pas été optimisée. En effet, ce brevet ne décrit pas les conditions critiques que doit remplir la charge avant. En particulier, on ne décrit pas la vitesse critique du noyau, l'épaisseur du revêtement et le rapport hauteur/calibre. De plus, il est bien précisé que le projectile décrit n'empêche pas l'activation du blindage actif. C'est pourquoi un écran de forte épaisseur (0,25 calibre) doit être utilisé pour protéger la charge arrière. Cette structure ne contribue pas à l'allègement du projectile.Patent FR-A 2,552,870, which constitutes the state of the art closest to the invention, describes a multipurpose projectile, the effectiveness of which against active armor has not been optimized. Indeed, this patent does not describe the critical conditions that the front load must meet. In particular, the critical speed of the core, the thickness of the coating and the height / gauge ratio are not described. In addition, it is clearly specified that the projectile described does not prevent the activation of the active armor. This is why a very thick screen (0.25 gauge) must be used to protect the rear load. This structure does not contribute to the lightening of the projectile.

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 la charge de tête génère un noyau capable de perforer un blindage actif sans l'initier, la deuxième charge formée pouvant alors être initiée après un temps très bref. Ce court est nécessaire pour éviter le rattrapage du noyau engendré par la première charge par le jet de la deuxième charge; mais il peut 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 core capable of puncturing an active armor without initiating it, the second charge formed can then be initiated after a very short time. This short is necessary to avoid the catching up of the core generated by the first charge by the jet of the second charge; but it can be reduced to a minimum taking into account the non-initiation of active shielding.

L'invention a donc pour objet une tête militaire comprenant une charge formée avant munie d'un revêtement métallique de révolution et une charge formée arrière montées en tandem et fonctionnant en séquence, destinée à l'agression de cibles blindées et notamment actives, caractérisée en ce que la charge avant engendre un noyau dont la vitesse d'impact sur la cible est comprise entre 1000 et 2500 m/s, en ce que le rapport de la hauteur du revêtement sur le calibre est compris entre 0,05 et 0,15, en ce que l'épaisseur moyenne du revêtement se situe entre 1% et 2% du calibre de la dite charge avant, et en ce que le retard de fonctionnement entre les deux charges se situe entre 50 et 300 µs.The subject of the invention is therefore a military head comprising a front formed charge provided with a metallic coating of revolution and a rear formed charge mounted in tandem and operating in sequence, intended for the aggression of armored and in particular active targets, characterized in that the front load generates a core whose impact speed on the target is between 1000 and 2500 m / s, in that the ratio of the height of the coating on the gauge is between 0.05 and 0.15 , in that the average thickness of the coating is between 1% and 2% of the caliber of said front load, and in that the operating delay between the two loads is between 50 and 300 µs.

Selon une caractéristique plus particulière,, la charge avant engendre un noyau dont la vitesse est d'environ 2000 m/s et le retard de foctionnement entre les deux charges est de l'ordre de 100 µs.According to a more particular characteristic, the front load generates a core whose speed is around 2000 m / s and the operating delay between the two loads is of the order of 100 μs.

Selon une autre caractéristique, la charge avant comporte un revêtement métallique conique d'angle au sommet compris entre 140 et 170 degrés.According to another characteristic, the front load comprises a conical metallic coating with an angle at the apex between 140 and 170 degrees.

La charge avant peut comporter un revêtement métallique conique d'angle au sommet sensiblement égal à 150 degrés et son l'épaisseur moyenne est de l'ordre de 1,6% du calibre de ladite charge avant.The front load may include a conical metal coating with an apex angle substantially equal to 150 degrees and its average thickness is of the order of 1.6% of the caliber of said front load.

Le revêtement peut être du type sphérique ou ellipsoïdal.The coating can be of the spherical or ellipsoidal type.

La charge avant peut comporter un revêtement métallique sphérique dont le rapport de la hauteur sur le calibre est de 0,1 et dont l'épaisseur moyenne est de l'ordre de 1,8% du calibre de ladite charge avant.The front load can comprise a spherical metallic coating whose ratio of height to the caliber is 0.1 and whose average thickness is of the order of 1.8% of the caliber of said front load.

Le revêtement de la charge avant peut être constitué par un alliage métallique de faible masse volumique, tel qu'un alliage d'aluminium.The coating of the front load can be constituted by a metallic alloy of low density, such as an aluminum alloy.

Le chargement explosif de la charge avant peut être constitué par un explosif à vitesse de détonation inférieure à 8000 m/s.The explosive charge of the front charge can consist of an explosive with a detonation speed of less than 8000 m / s.

Le chargement explosif de la charge avant peut être choisi dans le groupe constitué par le trinitrotoluène, le baratoi, ou un explosif composite.The explosive charge of the front charge can be chosen from the group consisting of trinitrotoluene, baratoi, or a composite explosive.

Le retard de fonctionnement entre la charge avant et la charge arrière est d'environ 100 gs.The operating delay between the front load and the rear load is approximately 100 gs.

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 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'art.The front charge 2 is constituted by a mass of explosive 4 limited towards the front by a metallic coating 5, and comprising at the rear a priming device 6 not shown in detail but known to those skilled in the art .

Le revêtement 5 peut être de forme conique, sphérique ou ellipsoïdal et plus généralement de révolution, mais ses caractéristiques géométriques doivent répondre aux conditions suivantes:The coating 5 can be conical, spherical or ellipsoidal and more generally of revolution, but its geometric characteristics must meet the following conditions:

- dans le cas d'un revêtement conique, l'angle au sommet doit être compris entre 140° et 170° et son épaisseur moyenne doit se situer entre 1% et 2% du calibre de la charge. Dans cet exemple particulier de réalisation, l'angle au sommet est de 150° et l'épaisseur est égale à 1,6% 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 0,05 et 0,15, les caractéristiques concernant son épaisseur étant identiques à celles données précédemment pour les revêtements de forme conique.- in the case of a conical coating, the angle at the top must be between 140 ° and 170 ° and its average thickness must be between 1% and 2% of the size of the load. In this particular embodiment, the apex angle is 150 ° and the thickness is equal to 1.6% 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 0.05 and 0.15, the characteristics concerning its thickness being identical to those given above for tapered coatings.

L'explosif 4 constituant cette charge doit être un explosif basse énergie dont la vitesse de détonation est inférieure à 8000 m/s tel que par exemple du trinitrotoluène, du baratol, ou un explosif composite.The explosive 4 constituting this charge must be a low energy explosive whose detonation speed is less 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 noyau par rapport à la cible soit inférieure à 2500 m/s, 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 nucleus relative to the target is less than 2500 m / s, this condition being necessary for the explosive constituting the active shield cannot be initiated.

La 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.This military head also includes a protective screen 9 whose function is to protect the rear load when the front load detonates.

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.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. Dans ce cas particulier de réalisation on utilise un retard de 100 lis.Similarly, the operating delay between the front and rear charges can be achieved for example using a detonating cord winding, an electronic device or a delay pyrotechnic component. In this particular embodiment, a delay of 100 μs is used .

Un avantage particulier de cette invention réside dans son adaption 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 resides in its adaption to perforate active armor while offering a lightened military head, the inter-charge protection 9 being able to be reduced taking into account 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.
