Description

PROTECTILE POUR MUNITION D'ARMES A FEU DE GROS PROTECTILE FOR AMMUNITION OF BIG FIREARMS
CALIBRE.CALIBER.
L'invention se rattache au secteur technique des munitions d'armes à feu de gros calibre conçues pour le tir de projectiles conformés pour éviter la pénétration à l'impact sur un individu notamment, constituant ainsi des munitions non létales.The invention relates to the technical sector of ammunition of large caliber firearms designed for the firing of shaped projectiles to avoid penetration on impact on an individual in particular, thus constituting non-lethal ammunition.
D'une manière parfaitement connue, l'ensemble de la munition présente des agencements et des moyens aptes à assurer la propulsion d'un projectile généralement constitué par un corps cylindrique délimitant une chambre interne apte à recevoir des produits à disperser, tels que de la poudre de CS, de la grenaille, des liquides... .In a perfectly known manner, all of the ammunition has arrangements and means capable of ensuring the propulsion of a projectile generally constituted by a cylindrical body delimiting an internal chamber capable of receiving products to be dispersed, such as CS powder, shot, liquids ....
Dans la plupart des cas, le projectile présente des systèmes pyrotechniques pour assurer la dispersion des produits. Par exemple, un détonateur, assujetti à un retardateur, peut être monté dans un logement formé coaxialement en bout du corps du projectile. Après introduction du projectile dans l'ensemble de la munition qui peut être constituée par un étui cylindrique, le système pyrotechnique est disposé en alignement coaxial avec par exemple une cartouche propulsive pour être allumé par les gaz de ladite cartouche. Les produits disperseurs sont disposés à l'intérieur du corps du projectile dont l'extrémité opposée à celle recevant le système pyrotechnique détonateur/ retardateur est obturée par un couvercle.In most cases, the projectile has pyrotechnic systems to ensure the dispersion of the products. For example, a detonator, subject to a retarder, can be mounted in a housing formed coaxially at the end of the body of the projectile. After introduction of the projectile throughout the munition which can be constituted by n u cylindrical casing, the pyrotechnic system is disposed in coaxial alignment with for example a propellant cartridge to be turned on by said gas cartridge. The dispersing products are arranged inside the body of the projectile, the end opposite to that receiving the pyrotechnic detonator / retarder system is closed by a cover.
Le fait d'utiliser un système pyrotechnique pour la dispersion des produits présente certains inconvénients, parmi lesquels on peut citer les risques d'incendie, l'effet calorifique qui produit un phénomène ascendant sur les produits pulvérisés, l'éventuelle transformation chimique des produits pulvérisés et, plus généralement, tous les risques dus à l'emploi d'un explosif. On observe également que la précision du tir est limitée à une distance relativement courte d'environ dix mètres. Or, il s'est avéré important de pouvoir conserver cette précision jusqu'à une distance d'environ trente mètres.The fact of using a pyrotechnic system for the dispersion of the products has certain drawbacks, among which one can cite the risk of fire, the calorific effect which produces an ascending phenomenon on the sprayed products, the possible transformation chemical of the sprayed products and, more generally, all the risks due to the use of an explosive. It is also observed that the accuracy of the shot is limited to a relatively short distance of about ten meters. However, it has been important to be able to maintain this accuracy up to a distance of about thirty meters.
L'invention s'est fixée pour but de remédier à ces inconvénients de manière simple, sûre, efficace et rationnelle.The object of the invention is to remedy these drawbacks in a simple, safe, efficient and rational manner.
Le problème que se propose de résoudre l'invention est de réaliser un projectile pour tout type de munition d'armes à feu de gros calibre du type non létale supprimant toute utilisation d'un système pyrotechnique pour la dispersion des produits contenant ledit projectile, tout en ayant pour but d'obtenir une grande précision du tir sur des distances beaucoup plus longues, d'environ trente mètres.The problem which the invention proposes to solve is to produce a projectile for any type of ammunition of large caliber firearms of the non-lethal type eliminating any use of a pyrotechnic system for dispersing the products containing said projectile, all with the aim of obtaining great accuracy in shooting over much longer distances, of around thirty meters.
Pour résoudre un tel problème, il a été conçu et mis au point un projectile constitué par un corps cylindrique délimitant une chambre interne apte à recevoir des produits à disperser. L'extrémité libre du corps du projectile présente une partie délimitant un volume interne contenant un fluide gazeux, notamment de l'air, ladite partie étant apte à être déformée élastiquement sous l'effet d'un impact pour créer, sous l'effet de compression du fluide, une force apte à assurer la dispersion des produits par des agencements que présente le corps.To solve such a problem, a projectile consisting of a cylindrical body delimiting an internal chamber capable of receiving products to be dispersed has been designed and developed. The free end of the projectile body has a part delimiting an internal volume containing a gaseous fluid, in particular air, said part being capable of being elastically deformed under the effect of an impact to create, under the effect of compression of the fluid, a force capable of ensuring the dispersion of the products by arrangements which the body presents.
Pour résoudre le problème posé de la compression de l'air au moment de l'impact du projectile, la partie délimitant le volume interne est constitué par une ogive creuse en matière souple, notamment caoutchouteuse. Pour résoudre le problème posé d'assurer la dispersion des produits sous l'effet de la compression du fluide gazeux : la chambre interne recevant les produits à disperser est constituée par une tuyère disposée coaxialement à l'ogive ; - la tuyère débouche dans une partie du corps en matériau rigide opposée coaxialement à l'ogive et faisant office de réservoir, ladite partie présentant les agencements de dispersion des produits ;To solve the problem of air compression at the time of the impact of the projectile, the part delimiting the internal volume is constituted by a hollow warhead made of flexible material, in particular rubbery. To solve the problem posed of ensuring the dispersion of the products under the effect of the compression of the gaseous fluid: the internal chamber receiving the products to be dispersed is constituted by a nozzle disposed coaxially with the warhead; - The nozzle opens into a part of the body of rigid material opposite coaxially to the warhead and acting as a reservoir, said part having the arrangements for dispersing the products;
- les agencements de dispersion des produits sont constitués par des orifices débouchants disposés de façon annulaire sur la périphérie du réservoir.- The arrangements for dispersing the products consist of through orifices arranged annularly on the periphery of the tank.
Un autre problème que se propose de résoudre l'invention est d'assurer la retenue de l'ensemble de produis dispersants à l'intérieur du projectile et avant l'impact de ce dernier. Un tel problème est résolu en ce que le fond de la tuyère et les orifices sont obturés d'une manière étanche par un moyen s'escamotant sous la pression exercée par les produits et le fluide comprimé.Another problem which the invention proposes to solve is to ensure the retention of the set of dispersing agents inside the projectile and before the impact of the latter. Such a problem is solved in that the bottom of the nozzle and the orifices are closed in a sealed manner by means which retract under the pressure exerted by the products and the compressed fluid.
Pour résoudre le problème posé d'augmenter la précision du tir, le fond de résevoir présente extérieurement un profil coaxial faisant office d'empennage pour assurer la stabilité de l'ensemble dudit projectile au moment du tir.To solve the problem of increasing the accuracy of the shot, the tank bottom has an externally coaxial profile acting as a tail unit to ensure the stability of all of said projectile at the time of the shot.
L'invention est exposée ci-après plus en détail à l'aide des dessins annexés dans lesquels :The invention is set out below in more detail with the aid of the appended drawings in which:
- la figure 1 est une vue en coupe longitudinale du projectile ;- Figure 1 is a longitudinal sectional view of the projectile;
- la figure 2 est une vue en coupe transversale selon la ligne 2-2 de la figure 1 ;- Figure 2 is a cross-sectional view along line 2-2 of Figure 1;
- la figure 3 est une vue en coupe transversale selon la ligne 3-3 de la figure 1 ; - la figure 4 est une vue en coupe longitudinale montrant l'introduction du projectile dans une munition ;- Figure 3 is a cross-sectional view along line 3-3 of Figure 1; - Figure 4 is a longitudinal sectional view showing the introduction of the projectile into a munition;
- la figure 5 est une vue en coupe longitudinale montrant l'impact du projectile et la dispersion concomitante des produits.- Figure 5 is a longitudinal sectional view showing the impact of the projectile and the concomitant dispersion of the products.
Comme le montre la figure 1, le projectile comprend un corps de forme générale cylindrique désigné par son ensemble par (1). L'extrémité libre du corps (1) présente une ogive creuse (2) en matière souple, notamment caoutchouteuse. Le volume interne (2a) de l'ogive (2) renferme un fluide gazeux. Plus particulièrement, ce volume (2a) contient naturellement de l'air.As shown in Figure 1, the projectile comprises a generally cylindrical body designated by its assembly by (1). The free end of the body (1) has a hollow warhead (2) made of flexible material, in particular rubbery. The internal volume (2a) of the warhead (2) contains a gaseous fluid. More particularly, this volume (2a) naturally contains air.
L'ogive (2) est accouplée, d'une manière démontable, en bout d'une partie (la) du corps qui fait office de réservoir. Cette partie (la) est réalisée en matériau rigide, par exemple en matière plastique. De même, le réservoir (la) délimite coaxialement à l'ogive (2), une tuyère (lb) recevant les produits dispersants (P). Cette tuyère (lb) constitue avec le réservoir (la) un ensemble monobloc ou bien est indépendante du réservoir (la) en y étant fixée de manière rapportée. La tuyère (lb) apparaît donc à l'intérieur du réservoir (la) en délimitant une section tronconique dégressive en direction du fond (lai) dudit réservoir. A noter que l'ogive (2) peut être accouplée entre l'extrémité libre et ouverte de réservoir (la) et une collerette (lbl) que présente la tuyère (lb). Le réservoir (la) présente des orifices débouchants (le) disposés de façon annulaire sur la périphérie dudit réservoir très sensiblement au niveau de la zone de raccordement de l'ogive (2).The warhead (2) is coupled, in a removable manner, at the end of a part (la) of the body which acts as a reservoir. This part (la) is made of rigid material, for example plastic. Likewise, the reservoir (la) delimits coaxially with the warhead (2), a nozzle (lb) receiving the dispersants (P). This nozzle (lb) constitutes with the reservoir (la) a one-piece assembly or else is independent of the reservoir (la) by being attached to it in a reported manner. The nozzle (lb) therefore appears inside the tank (la) by delimiting a tapering tapered section in the direction of the bottom (lai) of said tank. Note that the warhead (2) can be coupled between the free and open end of the tank (la) and a flange (lbl) that has the nozzle (lb). The reservoir (la) has through orifices (le) arranged annularly on the periphery of said reservoir very substantially at the level of the connection region of the warhead (2).
Le fond (lai) de réservoir est arrondi et est raccordé à la partie cylindrique (la2) du réservoir par une forme très sensiblement tronconique (la3). Les produits (P) sont maintenus à l'intérieur du réservoir, notamment au niveau de la tuyère (lb) par tout moyen étanche susceptible de s'escamoter sous la pression exercée par ledit produit et l'air comprimé au moment de l'impact comme il sera indiqué dans la suite de la description. Par exemple chacune des extrémités (lbl) et (lb2) de la tuyère (lb), ainsi que les orifices (le), sont obturées par un autocollant (3).The tank bottom (lai) is rounded and is connected to the cylindrical part (la2) of the tank by a very substantially frustoconical shape (la3). The products (P) are kept inside the tank, in particular at the nozzle (lb) by any sealed means capable of being retracted under the pressure exerted by said product and the compressed air at the time of impact as will be indicated in the following description. For example, each of the ends (lbl) and (lb2) of the nozzle (lb), as well as the orifices (le), are closed off with a sticker (3).
Le fond (lai) du réservoir est prolongé extérieurement par un profil coaxial (ld) dont l'extrémité libre constitue un empennage (ldl) pour assurer la stabilité de l'ensemble du projectile au moment du tir. Cet empennage (ldl) peut être constitué par un disque en matière souple ou garni d'une matière évitant toute blessure dans l'hypothèse où le projectile basculerait à 90° au moment de l'impact.The bottom (lai) of the tank is extended externally by a coaxial profile (ld) whose free end constitutes a tail (ldl) to ensure the stability of the entire projectile at the time of firing. This empennage (ldl) can be constituted by a disc in flexible material or lined with a material avoiding any injury in the event that the projectile would tilt at 90 ° at the time of impact.
L'ensemble du projectile tel que défini est destiné à être introduit dans une munition présentant des moyens aptes à assurer sa propulsion. Par exemple et comme le montre la figure 4, la munition comprend un étui (4) de forme générale cylindrique en matière plastique souple par exemple. L'une des extrémités de l'étui (4) est fermée et présente coaxialement une chambre concentrique (4a) apte à recevoir un ensemble de propulsion (5) de l'ensemble projectile. Le projectile est logé dans l'étui (4) après avoir été introduit par son ouverture (4b). Bien évidemment, l'ogive déformable (2) est disposée du côté de l'ouverture de l'étui (4). Les caractéristiques de la munition notamment au niveau du moyen de propulsion ressortent par exemple de l'enseignement du brevet PCT/FR 93/00466, dont le demandeur de la présente est également titulaire.The entire projectile as defined is intended to be introduced into a munition having means capable of ensuring its propulsion. For example and as shown in Figure 4, the ammunition comprises a case (4) of generally cylindrical shape made of flexible plastic, for example. One end of the case (4) is closed and has a concentric chamber (4a) coaxially adapted to receive a propulsion assembly (5) of the projectile assembly. The projectile is housed in the case (4) after being introduced through its opening (4b). Obviously, the deformable warhead (2) is disposed on the side of the opening of the case (4). The characteristics of the ammunition, in particular at the level of the propulsion means, emerge for example from the teaching of the patent PCT / FR 93/00466, of which the applicant for this present is also the holder.
Comme le montre la figure 5, après avoir procédé au tir du Qprojectile en utilisant tout type d'arme appropriée, l'impact dudit projectile a pour effet de provoquer la déformation de l'ogive (2) et, d'une manière concomitante, la compression de l'air qui a pour effet de chasser les produits (P) en assurant d'une manière correspondante leur dispersion au travers des orifices (le). Sous l'effet de la pression exercée par les produits et l'air comprimé, les moyens d'obturation étanches (3) sont automatiquement escamotés.As shown in Figure 5, after firing the Qprojectile using any suitable type of weapon, the impact of said projectile has the effect of causing the deformation of the warhead (2) and, concomitantly, the compression of the air which has the effect of expelling the products (P) by ensuring in a corresponding manner their dispersion to the through orifices (le). Under the effect of the pressure exerted by the products and the compressed air, the sealed closure means (3) are automatically retracted.
Il apparaît donc que seule la compression de l'air résultant de l'écrasement à l'impact de l'ogive creuse (2), est nécessaire pour assurer, en combinaison avec la tuyère (lb), la dispersion des produits (P) au travers des orifices (le).It therefore appears that only the compression of the air resulting from the crushing on impact of the hollow warhead (2) is necessary to ensure, in combination with the nozzle (lb), the dispersion of the products (P) through orifices (le).
Les avantages ressortent bien de la description. Particulièrement, on souligne et on rappelle :The advantages are apparent from the description. In particular, we emphasize and remember:
- suppression des risques dus à l'emploi d'un explosif - suppression des risques incendiaires- elimination of risks due to the use of an explosive - elimination of arson risks
- suppression de l'effet calorique susceptible de créer un phénomène ascendant sur le produit pulvérisé- elimination of the caloric effect liable to create an upward phenomenon on the sprayed product
- suppression de l'éventuelle transformation chimique des produits pulvérisés.- elimination of the possible chemical transformation of the sprayed products.
Sans pour cela sortir du cadre de l'invention, le fluide gazeux nécessaire sous un effet de compression à assurer la dispersion des produits, peut être issu d'un réservoir du type de ceux utilisés pour les carabines à air comprimé et dont l'ouverture peut être assurée par percution à inertie ou au moyen d'une amorce avec retardateur agissant sur un percuteur pour des projectiles lancés manuellement ou par un lanceur en tir courbe. Without departing from the scope of the invention, the gaseous fluid necessary under a compression effect to ensure the dispersion of the products, can come from a reservoir of the type of those used for air rifles and whose opening can be ensured by percussion with inertia or by means of a primer with retarder acting on a striker for projectiles launched manually or by a launcher in curved fire.
