Abstract
Le secteur technique de l'invention est celui des têtes militaires comportant plusieurs charges creuses. La tête militaire selon l'invention est constituée par une charge explosive formée (2) capable de générer un noyau dont la vitesse est inférieure à 2500 m/s de manière à ne pas faire détoner les blindages actifs, et une charge formée arrière (3) destinée à la perforation complète du blindage. Application à la perforation des blindages simple, feuilletés, composites ou actifs à l'aide de roquettes, missiles ou obus.The technical sector of the invention is that of military warheads comprising several hollow charges. The military head according to the invention consists of a formed explosive charge (2) capable of generating a nucleus whose speed is less than 2500 m / s so as not to detonate the active armor, and a rear formed charge (3 ) intended for the complete perforation of the shielding. Application to the perforation of simple, laminated, composite or active shields using rockets, missiles or shells.
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.The invention relates to a military head which can be used in particular in shells, rockets and missiles to attack battle tanks, whether their armor is simple, laminated, 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 entraine, en séquence, celle de la deuxième avec toutefois un retard de fonctionnement (ΔT) 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 leads, in sequence, to that of the second with, however, an operating delay (ΔT) 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.
Le retard ΔT optimal varie 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:
- 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.
The optimal delay ΔT 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 du ΔT peut avoir comme conséquences qui sont autant d'inconvénients:
- l'augmentation de la distance d'action optimale de la 2ème charge explosive
- la diminution de la vitesse du projectile
- l'augmentation des intéractions entre les deux charges.An increase in ΔT can have the following consequences which are all disadvantages:
- increase in the optimal distance of action of the 2nd explosive charge
- decrease in projectile speed
- the increase in interactions between the two charges.
L'invention vise donc à palier les inconvénients précités, en proposant une tête militaire à charges formées montées en tandem et 25 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 retard étant nécessaire pour éviter le rattrapage du noyau engendré par la 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 so that the head charge generates a core capable of perforating an active armor without initiating it, second charge formed can then be initiated after a very short time, this short delay being necessary to avoid catching up of the core 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, est caractérisée par le fait que la charge avant engendre un noyau dont la vitesse d'impact sur la cible est comprise entre 1000 et 2500 m/s et en ce que le retard de fonctionnement entre les deux charges se situe entre 50 et 300 µs.The military head, according to the invention, is characterized in that the front load generates a nucleus whose impact speed on the target is between 1000 and 2500 m / s and in that the operating delay between the two charges is between 50 and 300 µs.
Selon une caractéristique plus particulière la charge avant engendre un noyau dont la vitesse est de l'ordre de 2000 m/s, et le retard de fonctionnement 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 around 100 µs.
Selon une réalisation particulière, la charge avant comporte un revêtement métallique de forme conique d'angle au sommet compris entre 140° et 170° et plus précisément est égal à 150°, et dont l'épaisseur moyenne est comprise entre 1% et 2% et plus précisément est égale à 1,6% du calibre de la charge avant.According to a particular embodiment, the front load comprises a metallic coating of conical shape with an angle at the apex between 140 ° and 170 ° and more precisely is equal to 150 °, and whose average thickness is between 1% and 2% and more precisely is equal to 1.6% of the caliber of the front load.
Selon une autre variante, la charge avant comporte un revêtement métallique de révolution pouvant par exemple être sphérique ou ellipsoïdal dont le rapport de la hauteur sur le calibre est compris entre 0,05 et 0,15 et plus précisément est égale à 0,1 et dont l'épaisseur moyenne se situe entre 1% et 2% et plus précisément est égal à 1,8% du calibre de la charge avant.According to another variant, the front load comprises a metallic coating of revolution which can for example be spherical or ellipsoidal, the ratio of the height to the caliber being between 0.05 and 0.15 and more precisely is equal to 0.1 and whose average thickness is between 1% and 2% and more precisely is equal to 1.8% of the caliber of the front load.
Selon d'autres caractéristiques:
- l'explosif utilisé pour réaliser le chargement de la charge avant est un explosif à vitesse de détonation inférieure à 8000 m/s pouvant être par exemple un explosif composite, du trinitrotoluène ou du baratol
- le retard de fonctionnement entre la charge avant et la charge arrière est d'environ 100 µs.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 can for example be a composite explosive, trinitrotoluene or baratol
- the operating delay between the front load and the rear load is approximately 100 µs.
D'autres caractéristiques et avantages de l'invention apparaitront 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
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'artThe
Le revêtement 5 peut être de forme conique, sphérique ou ellipsoïdal et plus généralement de révolution, mais ses caractéristiques géométriques doivent répondrent aux conditions suivantes:
- 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.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 140 ° and 170 ° and its average thickness must be between 1% and 2% of the size of the load. In this particular embodiment, the angle at the top 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
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 µs.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.
