Description

Le domaine de la présente invention est celui des projectiles destinés à agresser des structures dures du type comprenant par exemple des structures de pierre, brique, béton ou autres matériaux de construction.The field of the present invention is that of projectiles intended to attack hard structures of the type comprising for example stone structures, brick, concrete or other building materials.

De telles cibles sont habituellement dévolues à des équipes du génie qui sont chargées de venir placer des explosifs directement au contact de la structure.Such targets are usually assigned to engineering teams responsible for placing explosives directly in contact with the structure.

Mais de telles opérations sont délicates à réaliser d'un point de vue tactique.But such operations are difficult to carry out with a tactical point of view.

On a cherché à définir des projectiles tirables à distance de sécurité et pouvant occasionner des dégâts notables à de telles cibles.We tried to define projectiles that could be fired at safety distance and may cause damage notable to such targets.

Cependant ces dernières sont le plus souvent protégées par une couche plus ou moins épaisse de sacs de sable qui provoque l'initiation des charges explosives habituelles à des distances de la structure de pierre ou de béton qui sont trop grandes pour que des dégâts importants lui soient occasionnés.However, these are most often protected by a more or less thick layer of sandbags which initiates the usual explosive charges to distances from the stone or concrete structure which are too large for serious damage to it are occasioned.

On connaít par ailleurs des projectiles dotés de moyens permettant de distinguer les cibles suivant leur dureté.We also know of projectiles with means allowing to distinguish the targets according to their hardness.

Ainsi le brevet EP433254 sur lequel repose le préambule de la revendication 1, décrit un projectile comportant un double contacteur d'ogive. Un premier contact est fermé lors de l'impact sur une cible "molle", comme un aéronef ou un véhicule léger. Ce premier contact provoque l'initiation de la charge à l'issue d'un certain retard, c'est à dire pratiquement lorsque le projectile se trouve à l'intérieur de la cible.Thus patent EP433254 on which the preamble of claim 1 is based, describes a projectile comprising a double warhead switch. A first contact is closed upon impact on a "soft" target, such as an aircraft or a light vehicle. This first contact causes the initiation of the charge after a certain delay, that is practically when the projectile is at inside the target.

Un deuxième contact est fermé lors de l'impact sur une cible "dure", c'est à dire une cible que le projectile ne peut pas traverser, ce contact provoque une initiation immédiate de la charge explosive.A second contact is closed during the impact on a "hard" target, ie a target that the projectile does not can not cross, this contact causes an initiation immediately of the explosive charge.

Un tel projectile est capable de faire la distinction entre une cible "molle" comme un véhicule léger ou un aéronef et une cible "dure" telle un char, mais il est inefficace contre les cibles du type immeubles ou casemates surprotégés.Such a projectile is capable of distinguishing between a "soft" target like a light vehicle or an aircraft and a "hard" target like a tank, but it is ineffective against targets of the overprotected buildings or casemates type.

Le brevet EP154580 décrit un projectile à charge tandem dans lequel le retard d'initiation entre les deux charges est fonction du temps de déplacement de l'écran de protection intercharges. Les charges formées de ce projectile sont initiées à distance de la cible blindée.Patent EP154580 describes a tandem charge projectile in which the initiation delay between the two charges is function of the protective screen movement time intercharges. The charges formed from this projectile are initiated at a distance from the armored target.

Le brevet DE3800976 décrit un projectile gyrostabilisé renfermant une charge creuse. L'ogive de ce projectile est conformée de façon à assurer un freinage en rotation du projectile à l'impact sur une cible. La charge formée est initiée dès l'impact sur la cible. Patent DE3800976 describes a gyro-stabilized projectile containing a hollow charge. The bullet of this projectile is shaped so as to ensure braking in rotation of the projectile on impact on a target. The charge formed is initiated upon impact on the target.

En effet, la dureté de l'impact sur des surprotections comme des sacs de sable provoque l'initiation immédiate de la charge et à une distance trop importante de la structure de l'immeuble pour pouvoir lui occasionner un dommage.Indeed, the hardness of the impact on overprotections like sandbags causes immediate initiation of the load and at too great a distance from the structure of the building to be able to cause it damage.

C'est un premier but de l'invention que de proposer un projectile de conception simple qui soit efficace contre les cibles dures telles les immeubles ou les casemates, même dotées de protections périphériques.It is a first aim of the invention to propose a simple design projectile effective against hard targets like buildings or bunkers, even with peripheral protections.

A cet effet le projectile proposé par l'invention est capable de traverser les protections périphériques comme les sacs de sable pour venir amener et initier la charge explosive au contact même de la structure dure.To this end, the projectile proposed by the invention is able to pass through peripheral protections such as sandbags to come bring and initiate the charge explosive even on contact with the hard structure.

C'est un autre but de l'invention que de proposer un tel projectile qui ait également une certaine efficacité contre les cibles blindées (comme les chars) et également une efficacité contre les cibles légères (comme les véhicules légers ou les aéronefs).It is another object of the invention to propose such a projectile which also has some effectiveness against armored targets (like tanks) and also a effectiveness against light targets (such as vehicles light or aircraft).

Ainsi l'invention a pour objet un projectile destiné à agresser des cibles dures telles des structures de pierre, brique ou béton et comprenant une charge explosive et des moyens d'amorçage de celle-ci, projectile caractérisé en ce qu'il comporte un pénétrateur, qui ne se déforme qu'à l'impact avec une cible d'une résistance mécanique minimale donnée, et un contacteur d'impact interne disposé entre le pénétrateur et la charge, projectile comportant des moyens assurant l'initiation de la charge en réponse à l'écrasement du contacteur interne et après que la charge explosive ait commencé à se déformer consécutivement à l'impact sur la cible.Thus, the subject of the invention is a projectile intended to assault hard targets such as stone structures, brick or concrete and comprising an explosive charge and means for initiating it, projectile characterized in that it has a penetrator, which only deforms impact with a target of minimum mechanical resistance data, and an internal impact switch located between the penetrator and charge, projectile comprising means initiating the charge in response to the crash of the internal contactor and after the explosive charge began to deform following the impact on the target.

L'invention combine ainsi des moyens perforants (le pénétrateur), qui assurent le passage du projectile au travers de surprotections éventuelles, et des moyens d'initiation de la charge qui déterminent un fonctionnement du type "squash head" (initiation après écrasement de la charge) au contact de la structure.The invention thus combines perforating means (the penetrator), which ensure the passage of the projectile to the through possible overprotections, and means of charge initiation which determine an operation "squash head" type (initiation after crushing the load) in contact with the structure.

Une telle combinaison donne au projectile une efficacité anti-structure supérieure à celle des projectiles connus. Such a combination gives the projectile an efficiency anti-structure superior to that of known projectiles.

Selon une autre caractéristique, la charge explosive est une charge formée comprenant un revêtement concave au contact d'un matériau explosif et délimitant une cavité.According to another characteristic, the explosive charge is a formed filler comprising a concave coating on the contact of an explosive material and delimiting a cavity.

Une telle caractéristique augmente l'efficacité anti-structure du projectile et permet de lui donner un mode de fonctionnement anti-blindé.Such a characteristic increases the anti-structure efficiency of the projectile and allows to give it a mode of anti-armored operation.

Selon un mode de réalisation, le contacteur interne est disposé dans la cavité délimitée par le revêtement, de telle sorte que le contacteur ne puisse être fermé qu'après que la charge ait commencé à se déformer suite à son impact sur une cible.According to one embodiment, the internal contactor is disposed in the cavity delimited by the coating, so that the contactor can only be closed after that the load has started to deform following its impact on a target.

Selon un autre mode de réalisation, les moyens assurant l'initiation de la charge comprennent un premier retard actionné par le contacteur interne.According to another embodiment, the means ensuring charge initiation include a first delay actuated by the internal contactor.

Selon une variante d'exécution, la charge explosive comporte au moins un matériau explosif donnant un effet de souffle renforcé lors de son initiation, par exemple une poudre d'aluminium.According to an alternative embodiment, the explosive charge contains at least one explosive material giving a breath strengthened during its initiation, for example a aluminum powder.

On pourra par exemple choisir comme matériau explosif de la charge un mélange d'hexogène et de poudre d'aluminium dans les proportions en masse suivantes: Hexogène 70% à 90%, Aluminium 30% à 10%.We could for example choose as explosive material the charge a mixture of hexogen and aluminum powder in the following proportions by mass: Hexogenous 70% to 90%, Aluminum 30% to 10%.

Selon un autre mode de réalisation de l'invention, le projectile comporte une ogive balistique disposée en avant du pénétrateur et portant un contact électrique actionné lors de l'impact sur une cible.According to another embodiment of the invention, the projectile has a ballistic warhead arranged in front of the indenter and carrying an actuated electrical contact upon impact on a target.

Avantageusement,le projectile comporte un sélecteur de mode de tir permettant de choisir entre une initiation de la charge consécutive à la fermeture du contacteur interne et une initiation suite à la fermeture du contact d'ogive.Advantageously, the projectile comprises a selector for shooting mode to choose between an initiation of the charge after closing the internal contactor and an initiation following the closure of the warhead contact.

Dans ce cas, lorsque le sélecteur est positionné de façon à choisir le contact d'ogive, l'écrasement de ce dernier lors de l'impact sur une cible provoquera une initiation immédiate de la charge.In this case, when the selector is positioned so to choose the warhead contact, the crushing of the latter upon impact on a target will cause an initiation immediate charge.

Avantageusement, lorsque le sélecteur est positionné de façon à choisir le contacteur interne, l'écrasement du contact d'ogive pourra provoquer une initiation de la charge par l'intermédiaire d'un deuxième retard. Advantageously, when the selector is positioned from way to choose the internal contactor, overwriting the warhead contact may cause initiation of the charge via a second delay.

L'invention sera mieux comprise à la lecture de la description qui va suivre de modes particuliers de réalisation, description faite en référence aux dessins annexés et dans lesquels:

  • la figure 1 représente en coupe axiale un projectile selon un premier mode de réalisation de l'invention,
  • la figure 2 est un schéma décrivant la structure des moyens d'initiation du projectile selon l'invention,
  • la figure 3 représente le détail d'une variante de réalisation d'un projectile selon l'invention.
The invention will be better understood on reading the description which follows of particular embodiments, description made with reference to the appended drawings and in which:
  • FIG. 1 represents in axial section a projectile according to a first embodiment of the invention,
  • FIG. 2 is a diagram describing the structure of the means for initiating the projectile according to the invention,
  • Figure 3 shows the detail of an alternative embodiment of a projectile according to the invention.

En se reportant à la figure 1, un projectile 1 selon l'invention comprend une charge explosive 2 disposée à l'intérieur d'une enveloppe cylindrique 3 en alliage léger par exemple en aluminium.Referring to FIG. 1, a projectile 1 according to the invention comprises an explosive charge 2 disposed at the interior of a cylindrical envelope 3 of light alloy for example aluminum.

L'enveloppe 3 est fermée à sa partie arrière par un fond 4 qui porte des ailettes de stabilisation 5 régulièrement réparties angulairement. Les ailettes sont articulées sur des chapes 6 portées par le fond 4 et se déploient lors du tir du projectile à partir d'un lanceur sans recul de type connu et non représenté.Envelope 3 is closed at its rear by a bottom 4 which carries stabilization fins 5 regularly distributed angularly. The fins are articulated on yokes 6 carried by the bottom 4 and are deployed during the projectile fired from a recoilless type launcher known and not shown.

La charge explosive 2 est une charge formée comprenant un revêtement concave 7 au contact d'un matériau explosif. Le revêtement délimite une cavité 8 qui est ici de forme conique.Explosive charge 2 is a formed charge comprising a concave coating 7 in contact with an explosive material. The coating defines a cavity 8 which is here of shape conical.

Le matériau explosif sera choisi de façon à engendrer lors de son initiation un effet de souffle renforcé, cela afin d'accroítre lors de l'initiation l'onde de choc à l'extérieur des structures bétonnées ce qui favorise leur fragmentation. Un tel matériau explosif permet aussi de donner un effet incendiaire à l'arrière des cibles du type véhicules blindés ou légèrement blindés.The explosive material will be chosen so as to generate during its initiation a reinforced breath effect, this in order to increase the shock wave at initiation the outside of concrete structures which favors their fragmentation. Such an explosive material also makes it possible to give an incendiary effect to the rear of targets of the type armored or lightly armored vehicles.

On choisira par exemple comme explosif un explosif comportant un additif réducteur finement divisé, tel une poudre métallique de préférence une poudre d'aluminium.For example, choose an explosive as an explosive containing a finely divided reducing additive, such as metallic powder, preferably aluminum powder.

On pourra par exemple utiliser de l'Hexal, c'est à dire un mélange d'hexogène et de poudre d'aluminium dans les proportions en masse suivantes: Hexogène 70% à 90%, Aluminium 30% à 10%. We could for example use Hexal, i.e. a mixture of hexogen and aluminum powder in the following mass proportions: Hexogene 70% to 90%, Aluminum 30% to 10%.

L'explosif peut être mis en place par compression dans l'enveloppe 3 équipée de son revêtement ou encore être usiné à ses dimensions définitives et collé dans l'enveloppe.The explosive can be placed by compression in the casing 3 equipped with its coating or else be machined to its final dimensions and glued into the envelope.

Il serait également possible d'utiliser d'autres types d'explosifs tels des explosifs composites et comportant un additif destiné à renforcer l'effet de souffle.It would also be possible to use other types explosives such as composite explosives and having a additive intended to reinforce the breath effect.

Le revêtement est réalisé en un matériau ductile (par exemple en cuivre), matériau susceptible de se déformer de façon à former un jet lors de l'initiation de l'explosif.The coating is made of a ductile material (by example copper), material susceptible to deformation of so as to form a jet during the initiation of the explosive.

Le revêtement est en appui sur une portée conique 9 aménagée sur un pénétrateur 10.The coating is supported on a conical bearing 9 fitted on a penetrator 10.

Cet appui permet d'assurer le maintien du revêtement et de la charge explosive lors des fortes décélérations qui interviennent à l'impact sur des sacs de sable.This support ensures the maintenance of the coating and of the explosive charge during strong decelerations which intervene on impact on sandbags.

Le pénétrateur 10 est réalisée en un matériau résistant à l'impact, par exemple en aluminium.The indenter 10 is made of a material resistant to impact, for example aluminum.

Il présente une forme externe profilée qui favorise la pénétration des surprotections légères (cloisons, sacs de sable).It has a contoured external shape which promotes penetration of light overprotections (partitions, bags of sand).

Le profil du pénétrateur est déterminé par l'homme du métier de façon à assurer une traversée sans déformation des sacs de sables ou autres protections légères. Ce profil est également défini de façon à ne pas résister à l'impact sur une structure dure telle que le béton ou la pierre.The profile of the penetrator is determined by the man of the loom so as to ensure a crossing without deformation of sandbags or other light protection. This profile is also defined so as not to withstand the impact on a hard structure such as concrete or stone.

Le pénétrateur 10 porte à sa partie arrière un épaulement 11 sur lequel l'enveloppe 3 vient en appui. L'enveloppe 3 est fixée au pénétrateur 10 par collage. Un autre mode de fixation pourrait être adopté par exemple des goupilles radiales ou un vissage.The indenter 10 has a shoulder at its rear part 11 on which the envelope 3 comes to bear. Envelope 3 is fixed to the indenter 10 by gluing. Another mode of fixing could be adopted for example pins radial or screwing.

La projectile 1 comporte aussi une coiffe balistique 12 réalisée en matériau léger, par exemple en composite de fibre de verre, et collée sur le pénétrateur 10. La coiffe est destinée à donner un profil aérodynamique au projectile de façon à réduire sa perte de vitesse sur sa trajectoire balistique.The projectile 1 also includes a ballistic cap 12 made of light material, for example composite of fiberglass, and glued to the penetrator 10. The cap is intended to give an aerodynamic profile to the projectile so as to reduce its loss of speed on its trajectory ballistic.

La coiffe 12 vient en appui sur le pénétrateur 10 au niveau de deux épaulements, un épaulement arrière 13 et un épaulement avant 14. The cap 12 comes to bear on the penetrator 10 at level of two shoulders, a rear shoulder 13 and a front shoulder 14.

La coiffe 12 porte à sa partie avant un contact électrique 15 qui comporte de façon connue une calotte métallique 15a légère (par exemple en laiton) collée sur une portée 16 de la coiffe et une couche métallique 15b déposée sur la partie avant de la coiffe. Les contacts 15a et 15b sont reliés par des conducteurs 17a et 17b à des moyens 18 d'amorçage de la charge explosive, moyens disposés dans le fond 4 et comportant notamment une amorce 18a.The cap 12 has a contact at its front part electric 15 which in a known manner includes a cap light metallic 15a (for example brass) bonded to a bearing surface 16 of the cap and a metal layer 15b deposited on the front part of the cap. Contacts 15a and 15b are connected by conductors 17a and 17b to means 18 for initiating the explosive charge, means arranged in the bottom 4 and comprising in particular a primer 18a.

Les conducteurs 17a et 17b pourront par exemple être collés sur la surface externe du projectile 1.The conductors 17a and 17b may for example be glued to the external surface of the projectile 1.

Le projectile 1 comporte enfin un contacteur interne 19 qui est disposé à l'intérieur de la cavité 8 délimitée par le revêtement 7.The projectile 1 finally comprises an internal contactor 19 which is disposed inside the cavity 8 delimited by the coating 7.

Le contacteur comporte un support 20 en matière isolante (par exemple une matière plastique ou composite) et à profil externe conique qui est collé sur le revêtement 7. Le support 20 porte une métallisation 19b sur une partie centrale, ainsi qu'une calotte métallique légère 19a collée sur une portée 21 du support 20.The contactor comprises a support 20 made of insulating material (e.g. plastic or composite) and profile external conical which is glued to the covering 7. The support 20 carries a metallization 19b on a part central, as well as a light metal cap 19a glued on a surface 21 of the support 20.

Les contacts 19a et 19b sont reliés aux moyens d'amorçage 18 par des conducteurs 22a et 22b. Les conducteurs doivent traverser la charge à un endroit tel qu'ils ne soient pas coupés ou détruits avant la fermeture du contact 19, ils doivent donc se trouver en arrière du contacteur dans le sens d'action du projectile.The contacts 19a and 19b are connected to the priming means 18 by conductors 22a and 22b. Drivers must cross the load in a place such that they are not cut or destroyed before contact 19 closes, they must therefore be behind the contactor in the direction of action of the projectile.

A cet effet, les conducteurs 22 traversent le revêtement 7 au niveau d'un trou axial 23 et traversent également sensiblement axialement le matériau explosif de la charge 2.For this purpose, the conductors 22 pass through the coating 7 at an axial hole 23 and also pass through substantially axially the explosive material of the charge 2.

La mise en place du contacteur interne 19 à l'intérieur de la cavité 8 délimitée par le revêtement 7 a pour effet de ne permettre sa fermeture que lorsque la charge a commencé à se déformer suite à son impact sur une cible.The installation of the internal contactor 19 inside of the cavity 8 delimited by the coating 7 has the effect of only allow it to close when the charge has started to deform following its impact on a target.

La figure 2 montre schématiquement les moyens d'initiation du projectile selon l'invention.Figure 2 shows schematically the initiation means of the projectile according to the invention.

Ces moyens comprennent un sélecteur de mode de tir 24 qui est de préférence disposé à l'extérieur du projectile et relié à celui-ci par des conducteurs 25 (voir figure 1). Il sera monté par exemple sur le tube de l'arme. These means include a fire mode selector 24 which is preferably placed outside the projectile and connected to it by conductors 25 (see Figure 1). he will be mounted for example on the barrel of the weapon.

Le sélecteur 24 permet de choisir entre un mode "anti structure" (dans lequel les contacts 24a et 24b sont reliés) et un mode "anti-blindé" (dans lequel les contacts 24a et 24c sont reliés).The selector 24 makes it possible to choose between an "anti" mode structure "(in which the contacts 24a and 24b are connected) and an "anti-armored" mode (in which the contacts 24a and 24c are connected).

Le mode "anti-structure" correspond à un choix de l'initiation de la charge explosive consécutive à la fermeture du contacteur interne 19.The "anti-structure" mode corresponds to a choice of initiation of the explosive charge following the closure of the internal contactor 19.

Le mode "anti-blindé" correspond à un choix de l'initiation de la charge explosive consécutive à la fermeture du contact de coiffe 15.The "anti-armored" mode corresponds to a choice of initiation of the explosive charge following the closure of the cap contact 15.

Les moyens d'initiation comprennent une source d'énergie 26 qui pourra être constituée par une pile amorçable ou encore par un ou plusieurs condensateurs chargés avant le tir. L'amorce électrique 18a est reliée d'une part à la source d'énergie 26 et d'autre part au contact 24a du sélecteur de mode de tir.The initiation means include a source of energy 26 which may be constituted by a bootable battery or again by one or more capacitors charged before shoot. The electrical primer 18a is connected on the one hand to the energy source 26 and on the other hand in contact 24a of the fire mode selector.

Les métallisations 15b du contact de coiffe et 19b du contacteur interne sont reliées en parallèle à la source d'énergie 26.The metallizations 15b of the cap contact and 19b of the internal contactor are connected in parallel to the source of energy 26.

La calotte conductrice 15a du contact de coiffe est reliée au contact 24c du sélecteur de mode de tir 24.The conductive cap 15a of the cap contact is connected to contact 24c of the firing mode selector 24.

La calotte conductrice 19a du contacteur interne est reliée au contact 24b du sélecteur de mode de tir 24 par l'intermédiaire d'un premier retard électronique 27 (qui pourra éventuellement être omis en fonction de la structure du projectile comme cela sera précisé par la suite).The conductive cap 19a of the internal contactor is connected to the contact 24b of the fire mode selector 24 by through a first electronic delay 27 (which could possibly be omitted depending on the structure of the projectile as will be explained later).

Un deuxième retard électronique 28 est disposé en parallèle entre les contacts 24a et 24c du sélecteur de mode de tir.A second electronic delay 28 is arranged in parallel between contacts 24a and 24c of the mode selector shooting.

Le fonctionnement du projectile est le suivant.The operation of the projectile is as follows.

Lorsque le tireur souhaite détruire une structure (surprotégée ou non), il choisit le mode approprié sur le sélecteur de tir 24. Lors de l'impact du projectile sur les protections externes éventuelles, le contact de coiffe 15 se ferme ce qui ne provoque pas l'initiation de la charge mais initie le retard 28. When the shooter wishes to destroy a structure (overprotected or not), he chooses the appropriate mode on the fire selector 24. During the impact of the projectile on the any external protection, the cap contact 15 closes which does not initiate charge initiation but initiates the delay 28.

La coiffe balistique 12 est détruite par le premier impact, mais le pénétrateur 10 est suffisamment résistant et a un profil adapté pour permettre la traversée des surprotections (tels les sacs de sable) sans dommage pour la charge explosive.Ballistic cap 12 is destroyed by the first impact, but the penetrator 10 is strong enough and has a suitable profile to allow the crossing of overprotections (such as sandbags) without damage to the explosive charge.

Lorsque le pénétrateur 10 arrive en contact avec la structure dure en béton, pierre ou brique, il se détruit.When the penetrator 10 comes into contact with the hard structure in concrete, stone or brick, it destroys itself.

Le revêtement 7 arrive alors en contact avec la structure dure et sa base se trouve écrasée à son tour. La charge explosive se déforme et l'explosif disposé au niveau de la base du revêtement s'écrase aussi sur la cible.The coating 7 then comes into contact with the structure hard and its base is crushed in turn. Load explosive deforms and the explosive disposed at the level of the base of coating also crashes on target.

Après déformation suffisante de la charge explosive, le contacteur interne 15 se trouve fermé, ce qui provoque l'initiation de la charge.After sufficient deformation of the explosive charge, the internal contactor 15 is closed, causing charge initiation.

Dans le cas du premier mode de réalisation du projectile décrit en référence à la figure 1, le retard 27 pourra être omis, car on est assuré que la charge se trouve écrasée sur la structure dure au moment ou se ferme le contacteur 19.In the case of the first embodiment of the projectile described with reference to FIG. 1, the delay 27 may be omitted, because we are sure that the load is crushed on the structure lasts when the contactor 19 closes.

Sur une cible type structure, l'effet du projectile selon l'invention est donc un effet combiné qui associe la formation d'un jet par la partie non déformée du revêtement, et un effet de surpression dû à l'initiation de l'explosif écrasé sur la cible (effet "Squash Head"). Une telle combinaison donne un effet perforant particulièrement efficace sur les structures de béton, pierres ou briques.On a structure type target, the effect of the projectile according to the invention is therefore a combined effect which combines the formation of a jet by the non-deformed part of the coating, and an overpressure effect due to the initiation of the explosive crashed on the target ("Squash Head" effect). Such a combination gives a particularly perforating effect effective on concrete, stone or brick structures.

L'effet "Squash Head" se trouve également renforcé par l'adoption d'un explosif à effet de souffle important comme l'Hexal.The "Squash Head" effect is also enhanced by the adoption of a significant blast explosive such as the Hexal.

Le retard 28 sera choisi de telle sorte qu'il ne puisse provoquer l'initiation de la charge avant écrasement du contacteur 19. Le retard 28 a pour fonction d'assurer une auto destruction du projectile dans le cas où il ne rencontrerait pas de structure dure susceptible de déformer le pénétrateur 10. On pourra par exemple choisir un retard de l'ordre de 5 à 20 millisecondes. Delay 28 will be chosen so that it cannot initiate the charge before crushing the contactor 19. The delay 28 has the function of ensuring a self-destruction of the projectile in case it does not meet no hard structure likely to deform the penetrator 10. We can for example choose a delay in the range of 5 to 20 milliseconds.

Cette autodestruction permet également de donner au projectile un effet vulnérant contre les cibles légères comme les véhicules routiers, les véhicules légers, les aéronefs ou les bunkers (c'est à dire les abris légers formés par un simple empilement de matériaux).This self-destruction also gives the projectile an offensive effect against light targets such as road vehicles, light vehicles, aircraft or bunkers (i.e. light shelters formed by a simple stack of materials).

Les cibles légères ne permettent pas de déformer le pénétrateur, et celui-ci donne un caractère perforant au projectile qui se trouve initiée à l'intérieur de la cible par le retard 28. L'efficacité du projectile est dans ce cas augmentée en raison du choix d'un explosif à effet de souffle comme l'Hexal qui donne un effet incendiaire supplémentaire.Light targets do not allow to distort the penetrator, and this gives a puncturing character to the projectile which is initiated inside the target by the delay 28. The effectiveness of the projectile is in this case increased due to choice of explosive effect breath like the Hexal which gives an incendiary effect additional.

Le mode autodestruction permet également, dans le cas où le pénétrateur ne rencontre pas de structure dure, d'assurer une initiation du projectile à l'intérieur de la surprotection ce qui permet de déblayer cette dernière en vue d'une attaque ultérieure.The self-destruction mode also allows, in the case where the indenter does not meet a hard structure, to ensure an initiation of the projectile inside the overprotection which allows to clear the latter in sight of a subsequent attack.

Lorsque le tireur souhaite détruire un véhicule blindé il choisit le mode anti-blindé sur le sélecteur de tir 24.When the shooter wishes to destroy an armored vehicle he selects anti-armor mode on the fire selector 24.

Lors de l'impact du projectile sur le véhicule, le contact de coiffe 15 se ferme, ce qui provoque une initiation instantanée de la charge explosive à une distance optimale de la cible, distance définie d'une façon connue par la longueur de la coiffe. Cette distance optimale permet au jet de charge creuse de se développer et d'avoir les meilleures performances de perforation de blindage.When the projectile hits the vehicle, the cap contact 15 closes, causing instant initiation of the explosive charge at a distance optimal target, distance defined in a known manner by the length of the cap. This optimal distance allows jet charge to develop and have the better armor piercing performance.

Le projectile selon l'invention permet donc avec un sélecteur à deux positions d'obtenir trois modes de fonctionnement différents: anti-blindé, anti-structure, anti-cible légère.The projectile according to the invention therefore allows with a two position selector to get three modes of operation different: anti-armored, anti-structure, anti-target slight.

Le projectile représentée à la figure 3 diffère de celui de la figure 1 par la position donnée au contacteur interne 20.The projectile represented in figure 3 differs from that in Figure 1 by the position given to the internal contactor 20.

Ce dernier est ici collé à l'intérieur de la cavité interne 29 du pénétrateur 10. Une telle disposition permet de faciliter le montage en autorisant le passage des conducteurs 22a et 22b par l'extérieur de la charge 2. The latter is here stuck inside the cavity internal 29 of the indenter 10. Such an arrangement allows to facilitate assembly by authorizing the passage of conductors 22a and 22b from the outside of the load 2.

Il est alors nécessaire de disposer un retard électronique 27 (voir figure 2) entre le contacteur interne 20 et les moyens d'amorçage, cela afin d'assurer que l'initiation en réponse à l'écrasement du contacteur 19 n'intervienne qu'après que la charge explosive ait commencé à se déformer suite à son impact sur la structure dure.It is then necessary to have an electronic delay 27 (see Figure 2) between the internal contactor 20 and the means of initiation, this to ensure that the initiation in response to the overwriting of the switch 19 does not intervene that after the explosive charge has started to deform following its impact on the hard structure.

On pourra donner au contacteur interne 20 toute position axiale entre le fond de la cavité interne 29 du pénétrateur 10 et le fond de la cavité 8 délimitée par le revêtement 7, il suffira d'ajuster le retard 27 en conséquence.The internal contactor 20 can be given any position axial between the bottom of the internal cavity 29 of the indenter 10 and the bottom of the cavity 8 delimited by the covering 7, it will suffice to adjust the delay 27 accordingly.

D'autres variantes de l'invention sont envisageables.Other variants of the invention can be envisaged.

Ainsi il est possible de définir un projectile ne comportant pas de contact d'ogive mais uniquement un contact interne 30.So it is possible to define a projectile comprising no warhead contact but only one contact internal 30.

Un tel projectile aura une efficacité anti-structure avec un comportement du type de celui décrit précédemment.Such a projectile will have an anti-structure efficiency with behavior of the type described above.

Il aura également une efficacité anti-blindé mais avec un mode de fonctionement identique à celui du mode anti-structure c'est à dire par initiation de la charge, non pas à distance optimale, mais après écrasement de la charge (fonctionnement du type "Squash Head").It will also have anti-armor efficiency but with a identical operating mode to that of anti-structure mode ie by charge initiation, not at optimal distance, but after crushing the load ("Squash Head" type operation).

Dans ce dernier cas, il est possible de ne pas prévoir de revêtement concave au contact du matériau explosif.In the latter case, it is possible not to plan concave coating in contact with explosive material.
