Definitions
- the subject of the present invention is a method of attacking armor consisting of active pre-shield and main shield in using a device explosive with a hollow charge.
- a shaper wave also called a screen
- a screen whose function is to deflect the detonation wave and make it toroidal.
- the shape of the screen is determined so that the detonation wave is deflected without loss substantial power, and in order to get the angle desired incidence of this wave on the lining of the cavity.
- the detonator When the detonator goes into action, it creates a detonation wave, via charge initiation 52, in the explosive charge 4.
- the wave of detonation propagates in the preload part (I) of the device, causing the formation, from the coating 13, a very fast jet and a slower nucleus, propagating on axis XX.
- the jet is intended for perforate an active screen without initiating it.
- the wave transmitter II is intended to conduct the detonation wave to the top 32 of the main charge III.
- This transmitter works like a shaped charge but whose initiation is reverse, that is to say it takes place at from its base 21. It is therefore formed from the coating 23, a jet propagating on the axis XX towards the rear of the device, jet which is lost, and a nucleus having the effect of close the top 32 of the main shaped charge III.
- the coating 23 is not essential; indeed, the closure of the apex 32 is not itself essential in principle for the operation of the main load; she has however, the advantage of opposing the passage of the core of the preload I which could disturb the formation of the main charge jet.
Description
La présente invention a pour objet un procédé pour attaquer un blindage constitué d'un préblindage actif et d'un blindage principal en utilisant un dispositif explosif à charge creuse.The subject of the present invention is a method of attacking armor consisting of active pre-shield and main shield in using a device explosive with a hollow charge.
On rappelle qu'une charge creuse est constituée essentiellement d'un chargement explosif de révolution dans lequel on a ménagé une cavité ouverte, recouverte d'un revêtement métallique, et d'un dispositif d'amorçage ayant également une symétrie de révolution. Lors de la détonation provoquée par le dispositif d'amorçage, le revêtement métallique de la cavité se projette sur l'axe de révolution de la charge ; il en résulte d'une part un jet de métal, qui se déplace à très grande vitesse sur cet axe, et, d'autre part, un noyau métallique animé d'une vitesse plus faible sur ce même axe, dans le même sens ou en sens opposé au jet précédent.Remember that a hollow charge is made up basically an explosive charge of revolution in which has provided an open cavity, covered with a metallic coating, and a starting device having also a symmetry of revolution. During the detonation caused by the ignition device, the metal coating of the cavity is projected onto the axis of revolution of the load; on the one hand this results in a jet of metal, which moves at very high speed on this axis, and, on the other hand, a nucleus metallic animated with a lower speed on this same axis, in the same or opposite direction to the previous throw.
On rappelle par ailleurs qu'on désigne habituellement par préblindage actif un blindage auxiliaire, disposé devant un blindage traditionnel, alors appelé blindage principal ; ce blindage auxiliaire est constitué de deux plaques en général d'acier (de quelques millimètres d'épaisseur) entre lesquelles est prise en sandwich une couche d'explosif relativement mince. Le préblindage peut être multicouche, c'est-à-dire comporter une pluralité de tels sandwiches. Le but du préblindage est que, lors de l'impact d'un projectile, la tête de ce dernier amorce la couche d'explosif en la pénétrant. L'explosion projette alors les plaques d'acier vers le projectile, perturbant ce dernier et diminuant son efficacité. En particulier, dans le cas d'un projectile à charge creuse, les plaques d'acier du préblindage perturbent le jet de la charge creuse au point de lui faire perdre en général la majeure partie de son pouvoir perforant contre le blindage principal.We also recall that we usually designate by active pre-shielding an auxiliary shielding, placed in front of a traditional armor, then called main armor; this auxiliary shield consists of two plates in general steel (a few millimeters thick) between which a relatively thin layer of explosive is sandwiched. The pre-shielding can be multilayer, that is to say include a plurality of such sandwiches. The purpose of pre-shielding is that, during the impact of a projectile, the head of the latter initiates the explosive layer by penetrating it. The explosion then projects the steel plates towards the projectile, disturbing the latter and decreasing its effectiveness. In particular, in the case of a hollow charge projectile, the steel plates of the armor disturb the jet of the shaped charge to the point of making it generally lose most of its piercing power against the main armor.
De tels préblindages actifs sont utilisés fréquemment pour la protection des véhicules blindés, tels que les chars de combat.Such active pre-shields are used frequently for the protection of armored vehicles, such as tanks fight.
Le problème qui se pose aux constructeurs de munitions anti-chars est alors le suivant : pour percer le blindage principal, il est préférable d'utiliser une charge creuse dont le pouvoir perforant, très grand, est susceptible de percer le blindage principal qui est en général très épais, mais, comme on l'a dit ci-dessus, les charges creuses sont particulièrement vulnérables à l'action des pré-blindages actifs.The problem facing manufacturers of anti-tank ammunition is the following: to pierce the main shield it is best to use a load hollow whose very great perforating power is likely to pierce the main shield which is generally very thick, but, as we said above, the shaped charges are particularly vulnerable to the action of active pre-armor.
Pour résoudre ce problème, différentes solutions sont connues.To solve this problem, different solutions are known.
Une première solution consiste à augmenter très fortement le pouvoir perforant nominal de la charge creuse afin que son pouvoir perforant résiduel (après perturbation par le pré-blindage) soit suffisant. Ce procédé est simple mais très coûteux en calibre de la charge creuse.A first solution consists in increasing very strongly the nominal perforating capacity of the shaped charge so that its residual perforating power (after disturbance by the pre-shielding) is sufficient. This process is simple but very expensive in size of the hollow charge.
Une seconde solution consiste à mettre en oeuvre des charges creuses à deux étages (souvent appelées charges tandem). La charge fonctionnant en premier, ou précharge, a pour fonction de neutraliser le préblindage :
- soit en l'initiant suffisamment tôt avant la mise en oeuvre de la deuxième charge, ou charge principale, permettant ainsi l'évacuation des plaques du préblindage avant l'arrivée du jet de la charge principale , comme illustré par le brevet US 3 416 449;
- soit en le perforant sans l'initier.
- either by initiating it sufficiently early before the implementation of the second charge, or main charge, thus allowing the evacuation of the pre-armor plates before the arrival of the jet of the main charge, as illustrated by US Patent 3,416,449 ;
- either by perforating it without initiating it.
Dans le premier cas, l'ajustage du procédé est difficile, notamment en ce qui concerne le délai qui doit séparer le fonctionnement des deux charges, et son emploi complique la structuration des munitions, notamment celles qui, destinées à être lancées par des canons, doivent subir de très fortes accélérations. Une solution correspondant au deuxième cas est notamment décrite clans la demande de brevet français n° 2 583 156, qui prévoit des moyens d'atténuation de l'effet de la précharge. Cette réalisation, comme la précédente, présente l'inconvénient d'augmenter l'encombrement du dispositif explosif.In the first case, the process adjustment is difficult, particularly with regard to the time limit which must separate the operation of the two charges, and its use complicates the structuring of ammunition, especially those which, intended to be launched by cannons, must undergo very strong accelerations. A solution corresponding to the second case is described in particular in the French patent application 2,583,156, which provides means for mitigating the effect of preload. This achievement, like the previous one, presents the disadvantage of increasing the size of the explosive device.
Par ailleurs, afin d'améliorer les performances d'une charge creuse, il est connu de disposer, entre le détonateur du dispositif d'amorçage et le chargement explosif, un conformateur d'onde, également appelé écran, dont la fonction est de dévier l'onde de détonation et la rendre torique. Cela permet, en faisant varier la forme de l'onde et de la cavité, d'augmenter la vitesse du jet perforant produit par la charge creuse, le rendement détonique de la charge, etc... La forme de l'écran est déterminée afin que l'onde de détonation soit déviée sans perte substantielle de puissance, et afin d'obtenir l'angle d'incidence voulu de cette onde sur le revêtement de la cavité. Cela conduit à des écrans encombrants, occupant une longueur qui peut être par exemple de l'ordre du tiers ou du quart de la longueur du chargement explosif, se traduisant encore par une augmentation de l'encombrement de la charge creuse et par la suite d'une diminution de son efficacité.Furthermore, in order to improve the performance of a hollow charge, it is known to have, between the detonator of the device for initiating and explosive charging, a shaper wave, also called a screen, whose function is to deflect the detonation wave and make it toroidal. This allows, in varying the shape of the wave and the cavity, increasing the speed of the perforating jet produced by the shaped charge, the detonic charge efficiency, etc. The shape of the screen is determined so that the detonation wave is deflected without loss substantial power, and in order to get the angle desired incidence of this wave on the lining of the cavity. This leads to bulky screens, occupying a length which can be for example of the order of a third or a quarter of the length of the explosive charge, again resulting in a increase in the size of the shaped charge and by the following a decrease in its effectiveness.
La présente invention a pour objet la diminution de l'encombrement longitudinal d'un dispositif explosif à charge creuse, du type comportant une charge principale à conformateur d'onde et une précharge pour le perçage d'un préblindage actif.The object of the present invention is to reduce the longitudinal dimensions of a charge explosive device hollow, of the type comprising a main load with a conformator wave and a preload for drilling an active pre-shield.
Plus précisément, l'invention a pour objet un procédé pour attaquer un blindage constitué d'un préblindage actif et d'un blindage principal en utilisant un dispositif explosif à charge creuse tel que défini par la revendication 1.More specifically, the subject of the invention is a method of attacking an armor consisting of active armor and main armor using a explosive device with a hollow charge as defined by the claim 1.
D'autres objets, particularités et résultats de l'invention ressortiront de la description suivante, donnée à titre d'exemple et illustrée par la figure unique annexée, qui représente une vue en coupe schématique d'un mode de réalisation du dispositif explosif à charge creuse selon l'invention.Other objects, features and results of the invention will emerge from the following description, given to as an example and illustrated by the single appended figure, which represents a schematic sectional view of a mode of production of the hollow charge explosive device according to the invention.
Sur la figure, on a représenté un dispositif explosif
comportant un chargement explosif 4 contenu dans une enveloppe
1, et dans lequel on a ménagé une cavité ouverte comportant
trois parties, repérées successivement 10, 20 et 30 du
chargement explosif vers l'ouverture ; la cavité est recouverte
d'une couche repérée, de la même manière, successivement 13,
23 et 33.
Un dispositif explosif en trois parties est connu du brevet US-A-3 416 449.
A l'extrémité arrière de l'enveloppe, qui est opposée
à l'ouverture de la cavité, est disposé un dispositif d'amorçage
5, comportant par exemple un détonateur 51 et une charge
d'initiation 52, amorcée par le détonateur 51 et ayant pour
fonction de transmettre la détonation au chargement 4.
L'ensemble possède une symétrie de révolution autour d'un axe
longitudinal XX.The figure shows an explosive device
comprising an explosive charge 4 contained in an envelope
1, and in which an open cavity has been provided, comprising
three parts, identified successively 10, 20 and 30 of the
explosive charge towards the opening; the cavity is covered
of a layer marked, in the same way, successively 13,
23 and 33.
An explosive device in three parts is known from US-A-3,416,449.
At the rear end of the envelope, which is opposite
at the opening of the cavity, is arranged a
Le dispositif comporte donc trois parties, à savoir, en partant de l'arrière du dispositif :
- une partie I, formant la précharge d'une charge du
type tandem décrit plus haut. Cette précharge est une charge
creuse, formée par la
cavité 10 ouverte vers l'avant, par exemple sensiblement de forme conique, lapartie 13 du revêtement et la partie du chargement explosif 4 l'entourant ; - une seconde partie II formant transmetteur d'onde,
formée de la
cavité 20 qui est ouverte des deux côtés mais plus ouverte vers l'arrière que vers l'avant du dispositif (par exemple sensiblement de forme tronconique), de la partie derevêtement 23 et du chargement explosif situé autour ; - une partie III formant la charge principale de la
charge tandem ; elle est constituée par une charge creuse
formée par la
cavité 30, ouverte vers l'avant et non complètement fermée à son sommet (par exemple sensiblement en forme de cône, de trompette ou de tulipe), la partie derevêtement 33 et la partie du chargement explosif 4 l'entourant.
- a part I, forming the preload of a tandem type load described above. This preload is a hollow charge, formed by the
cavity 10 open towards the front, for example substantially conical, thepart 13 of the covering and the part of the explosive charge 4 surrounding it; - a second part II forming a wave transmitter, formed by the
cavity 20 which is open on both sides but more open towards the rear than towards the front of the device (for example substantially of frustoconical shape), of thecovering part 23 and the explosive charge located around; - a part III forming the main load of the tandem load; it consists of a hollow charge formed by the
cavity 30, open towards the front and not completely closed at its top (for example substantially in the shape of a cone, trumpet or tulip), the coveringpart 33 and the part of the explosive charge 4 surrounding it.
Lorsque le détonateur entre en action, il crée une
onde de détonation, par l'intermédiaire de la charge
d'initiation 52, dans le chargement explosif 4. L'onde de
détonation se propage dans la partie précharge (I) du
dispositif, provoquant la formation, à partir du revêtement 13,
d'un jet très rapide et d'un noyau plus lent, se propageant sur
l'axe XX. Ainsi qu'il est dit plus haut, le jet est destiné à
perforer un préblindage actif sans l'initier.When the detonator goes into action, it creates a
detonation wave, via
La perforation sans initiation est obtenue en limitant l'énergie transmise par le jet à l'explosif du préblindage par unité de surface, l'énergie du jet étant notamment fonction de la nature du revêtement, de sa masse et de la vitesse du jet. A cet effet, on utilise pour le revêtement un matériau peu dense, par exemple un matériau plastique de type Nylon avec, pour la charge creuse, des paramètres tels qu'ils confèrent au jet une vitesse relativement élevée, afin qu'il n'y ait pas de risque de collision entre le jet de la précharge et celui de la charge principale.Perforation without initiation is obtained by limiting the energy transmitted by the jet to the explosive of the screening by unit of area, the energy of the jet being in particular a function of the nature of the coating, its mass and the speed of the jet. AT this effect, a sparse material is used for the coating, for example a nylon type plastic material with, for the shaped charge, parameters such that they give the jet a relatively high speed, so there is no risk of collision between the preload jet and the charge jet main.
L'onde de détonation arrivant à la base 11 du
revêtement 13 se présente de la même façon qu'une onde ayant
contourné un conformateur d'onde classique, dont la précharge I
remplit donc la fonction.The detonation wave arriving at base 11 of the
Le transmetteur d'onde II est destiné à conduire
l'onde de détonation jusqu'au sommet 32 de la charge principale
III. Ce transmetteur fonctionne comme une charge creuse mais
dont l'amorçage est inverse, c'est-à-dire qu'il s'effectue à
partir de sa base 21. Il se forme donc, à partir du revêtement
23, un jet se propageant sur l'axe XX vers l'arrière du
dispositif, jet qui est perdu, et un noyau ayant pour effet de
fermer le sommet 32 de la charge creuse principale III. Il est à
noter que le revêtement 23 n'est pas indispensable ; en effet,
la fermeture du sommet 32 n'est elle-même pas indispensable en
principe pour le fonctionnement de la charge principale ; elle a
toutefois pour avantage de s'opposer au passage du noyau de la
précharge I qui, lui, serait susceptible de perturber la
formation du jet de la charge principale. A cet effet, le
revêtement 23 peut être réalisé en un matériau métallique, par
exemple acier doux ou cuivre. Il est à noter également que la
cavité 20 du transmetteur d'onde a été représentée tronconique
mais que sa forme peut être autre : tulipe ou trompette par
exemple ; il peut également avoir un angle au sommet plus ou
moins grand, jusqu'à la forme cylindrique, l'angle étant
fonction des diamètres choisis pour la base 11 de la précharge
et le sommet 32 de la charge principale.The wave transmitter II is intended to conduct
the detonation wave to the
L'onde de détonation atteint ensuite la charge creuse
principale III, qui fonctionne alors comme une charge creuse
munie d'un conformateur d'onde. Le revêtement 33 peut être,
classiquement, métallique, en cuivre par exemple.The detonation wave then reaches the hollow charge
main III, which then functions as a shaped charge
fitted with a wave shaper. The
Le dispositif explosif décrit ci-dessus présente donc les avantages d'une structure de type tandem et d'une charge creuse comportant un conformateur d'onde, le tout sous un encombrement réduit. Par ailleurs, le fait que la précharge perce, dans l'amorcer, un préblindage actif permet de ne pas avoir à retarder le fonctionnement de la charge principale. Le dispositif selon l'invention présente en outre les avantages suivants :
- suppression des éventuels écrans intercharge, puisqu'ici le chargement explosif 4 est unique ;
- suppression du dispositif d'amorçage de la précharge : selon l'invention, un seul dispositif (5) assure l'amorçage de l'ensemble ;
- suppression des risques de destruction de la charge principale avant son fonctionnement : en effet, selon l'invention, il n'y a pas de rétroprojection possible de la précharge vers la charge principale ;
- grand calibre de la précharge (égal à celui de la charge principale) ;
- réduction de l'influence de l'angle de dérapage de la munition à l'impact, par réduction du délai de fonctionnement global.
- deletion of any intercharge screens, since here the explosive charge 4 is unique;
- elimination of the preload initiating device: according to the invention, a single device (5) ensures the priming of the assembly;
- elimination of the risks of destruction of the main charge before its operation: in fact, according to the invention, there is no possible rear projection of the preload to the main charge;
- large preload rating (equal to that of the main load);
- reduction of the influence of the sideslip angle of the ammunition at impact, by reduction of the overall operating time.
