Description

L'invention se rattache au secteur technique des munitions.The invention relates to the technical sector of ammunition.

Il est connu d'employer pour certains types d'armes à feu de gros calibre, des munitions spéciales permettant le tir de projectiles particuliers. Généralement, ce type d'arme est utilisé comme arme de défense. Les munitions sont par exemple constituées par un étui dont une extrémité est apte à recevoir le projectile, tandis que l'autre extrémité présente une chambre conformée pour recevoir une cartouche propulsive. Notamment, la cartouche propulsive est spécialement conçue pour le tir de projectiles dont la matière, le diamètre et le poids sont déterminés pour éviter, à courte distance, la pénétration à l'impact.It is known to use for certain types of large caliber firearms, special ammunition allowing the firing of particular projectiles. Generally, this type of weapon is used as a defense weapon. The ammunition is for example constituted by a case, one end of which is capable of receiving the projectile, while the other end has a chamber shaped to receive a propellant cartridge. In particular, the propellant cartridge is specially designed for the firing of projectiles whose material, diameter and weight are determined to avoid, at short distance, penetration on impact.

Le projectile, généralement exécuté sous forme d'une bille de gros diamètre, est logé dans un godet monté à libre coulissement et centré dans l'alésage de la partie correspondante d'un étui constituant le corps de la munition. Ce type de munition ressort, par exemple, de l'enseignement de la demande de brevet FR 8805255, dont le demandeur est également titulaire.The projectile, generally executed in the form of a large diameter ball, is housed in a cup mounted with free sliding and centered in the bore of the corresponding part of a case constituting the body of the ammunition. This type of ammunition is apparent, for example, from the teaching of patent application FR 8805255, of which the applicant is also the holder.

Le plus souvent, le projectile est réalisé dans un matériau qui n'est pas suffisamment souple, de sorte que la surface d'impact dudit projectile est limitée très sensiblement à la surface initiale générée par le volume du projectile. Or, dans certains cas il s'avère important que cette surface d'impact soit la plus importante possible.Most often, the projectile is made of a material which is not sufficiently flexible, so that the impact surface of said projectile is very substantially limited to the initial surface generated by the volume of the projectile. However, in some cases it is important that this impact surface is as large as possible.

Le problème que se propose de résoudre l'invention est de concevoir un projectile pour munitions d'arme à feu de gros calibre, les caractéristiques de ce projectile étant déterminées pour obtenir, à l'impact, une surface beaucoup plus importante que celle générée par le volume initial du projectile.The problem which the invention proposes to solve is to design a projectile for ammunition of large caliber firearms, the characteristics of this projectile being determined to obtain, on impact, a much larger surface area than that generated by volume initial of the projectile.

Pour résoudre ce problème, le projectile est constitué par un corps sphérique en matière souple, déterminée pour délimiter, après le tir, une surface d'impact très importante.To resolve this problem, the projectile is constituted by a spherical body made of flexible material, determined to delimit, after firing, a very large impact surface.

Le corps sphérique est réalisé en élastomère de polyuréthane et est soumis à un traitement apte à supprimer tout effet de viscosité.The spherical body is made of polyurethane elastomer and is subjected to a treatment capable of eliminating any effect of viscosity.

Un autre problème que se propose de résoudre l'invention est de donner au projectile une protection temporaire au moment du tir, compte-tenu des forces de pression exercées et de la matière souple utilisée pour ledit projectile, le problème étant de pouvoir guider ce projectile jusqu'à la sortie du canon en le maintenant dans sa forme d'origine.Another problem which the invention proposes to solve is to give the projectile temporary protection at the time of firing, taking into account the pressure forces exerted and the flexible material used for said projectile, the problem being to be able to guide this projectile until the exit of the barrel while maintaining it in its original form.

Un tel problème est résolu en ce que le projectile est logé dans un godet monté à libre coulissement et centré dans un alésage de la munition, ledit godet étant agencé pour conférer une certaine rigidité audit projectile au moment du tir.Such a problem is solved in that the projectile is housed in a cup mounted with free sliding and centered in a bore of the ammunition, said cup being arranged to confer a certain rigidity on said projectile at the time of the shooting.

Avantageusement, ce problème est résolu en ce que le projectile est logé dans le godet en interposant une enveloppe protectrice en matière étanche et non fibreuse et apte à envelopper, en partie, ledit projectile.Advantageously, this problem is solved in that the projectile is housed in the bucket by interposing a protective envelope made of waterproof and non-fibrous material and capable of enveloping, in part, said projectile.

Dans une autre forme de réalisation, en ayant toujours pour objectif d'augmenter la surface d'impact du projectile, ce dernier est constitué par un corps sphérique constituant une enveloppe en matériau souple, étanche et déformable, apte à délimiter un volume interne susceptible d'être rempli d'un fluide liquide ou pâteux.In another embodiment, always having the objective of increasing the impact surface of the projectile, the latter is constituted by a spherical body constituting an envelope made of flexible, waterproof and deformable material, capable of delimiting an internal volume capable of '' be filled with a liquid or pasty fluid.

Toujours dans le cas où le projectile est constitué par un corps sphérique constituant une enveloppe apte à délimiter un volume interne susceptible d'être rempli d'un fluide liquide ou pâteux, le matériau est sélectionné pour éclater au moment de l'impact, pour provoquer, d'une manière concomitante, la diffusion du fluide.Always in the case where the projectile is constituted by a body spherical constituting an envelope capable of delimiting an internal volume capable of being filled with a liquid or pasty fluid, the material is selected to burst at the moment of impact, to cause, in a concomitant manner, the diffusion of the fluid.

Un autre problème que se propose de résoudre l'invention est de pouvoir utiliser l'arme en toute circonstance, quelle que soit la température extérieure.Another problem which the invention proposes to solve is to be able to use the weapon in any circumstance, whatever the outside temperature.

Un tel problème est résolu en ce que le fluide liquide ou pâteux est sélectionné pour être insensible aux basses températures.Such a problem is solved in that the liquid or pasty fluid is selected to be insensitive to low temperatures.

Là encore, et pour résoudre le problème posé d'assurer la protection du projectile au moment du tir, jusqu'à sa sortie du canon, le projectile est logé dans un godet en deux parties distinctes détachables, ledit godet étanchéité dans un chambrage de la munition.Again, and to solve the problem of ensuring the protection of the projectile at the time of firing, until it leaves the barrel, the projectile is housed in a cup in two separate detachable parts, said sealing cup in a recess of the ammunition.

Pour résoudre le problème de donner une certaine rigidité au moment du tir à l'ensemble godet - projectile, la partie arrière du godet présente des agencements aptes à augmenter la rigidité de ce dernier, tout en assurant l'étanchéité au moment du tir.To solve the problem of giving a certain rigidity at the time of firing to the bucket - projectile assembly, the rear part of the bucket has arrangements capable of increasing the rigidity of the latter, while ensuring sealing at the time of firing.

Les agencements sont constitués par des nervures radiales extérieures disposées en débordement du fond de l'étui, en délimitant, en combinaison avec ledit étui, un bourrelet d'étanchéité.The arrangements are constituted by external radial ribs arranged in overflow from the bottom of the case, delimiting, in combination with said case, a sealing bead.

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 9 est une vue en coupe transversale à plus grande échelle, considérée selon la ligne 9-9 de la figure 8.FIG. 9 is a cross-sectional view on a larger scale, seen along line 9-9 of FIG. 8.

La figure 10 montre un autre exemple d'une munition pour arme à feu de gros calibre équipée du projectile selon une autre forme de réalisation.FIG. 10 shows another example of ammunition for a large caliber firearm equipped with the projectile according to another embodiment.

La figure 11 est une vue en coupe longitudinale d'une forme de réalisation du projectile.Figure 11 is a longitudinal sectional view of one embodiment of the projectile.

Comme indiqué, le projectile selon l'invention, désigné dans son ensemble par (P), trouve une application particulièrement avantageuse pour les munitions d'armes à feu à gros calibre.As indicated, the projectile according to the invention, generally designated by (P), finds a particularly advantageous application for ammunition of large caliber firearms.

La figure 1 montre un exemple nullement limitatif, d'une munition qui comprend de manière connue, un étui (E) généralement en matière plastique. L'une des extrémités de l'étui (E) présente une chambre apte à recevoir, par exemple, une cartouche propulsive (C). Le projectile (P) est contenu dans un élément formant godet (3), monté à libre coulissement et centré dans l'alésage dans la partie correspondante de l'étui (E).Figure 1 shows a non-limiting example of ammunition which comprises in known manner, a case (E) generally in plastic material. One end of the case (E) has a chamber capable of receiving, for example, a propellant cartridge (C). The projectile (P) is contained in a bucket element (3), mounted to slide freely and centered in the bore in the corresponding part of the case (E).

Selon l'invention, le projectile (P), compte-tenu du problème posé d'augmenter la surface d'impact, peut présenter différentes formes de réalisation, le godet (3) étant adapté en conséquence à chaque forme de réalisation.According to the invention, the projectile (P), taking into account the problem posed of increasing the impact surface, can have different embodiments, the bucket (3) being adapted accordingly to each embodiment.

De manière générale, le projectile constitue un corps sphérique, sans pour cela exclure d'autre formes géométriques, en fonction, par exemple, du type de munition employé.In general, the projectile constitutes a spherical body, without excluding other geometric shapes, depending, for example, on the type of ammunition used.

Dans la forme de réalisation illustrée aux figures 1 à 4, le projectile constitue un corps sphérique plein (6), en matière souple, déterminé pour délimiter après le tir, une surface d'impact très importante (figure 5). A cet égard, le corps (6) est réalisé en élastomère de polyuréthanne. Avantageusement, le corps (6) est soumis à un traitement apte à supprimer tout effet de viscosité. Par exemple, le corps sphérique (6) peut être trempé dans un bain de talc.In the embodiment illustrated in Figures 1 to 4, the projectile constitutes a solid spherical body (6), made of flexible material, determined to delimit after firing, a very large impact surface (Figure 5). In this regard, the body (6) is made of polyurethane elastomer. Advantageously, the body (6) is subjected to a treatment capable of eliminating any viscosity effect. For example, the spherical body (6) can be soaked in a talc bath.

Comme indiqué, le corps (6) est logé dans le godet (3). Selon l'invention l'alésage du godet, dont le fond est hémisphérique, reçoit une enveloppe protectrice (5) en matière étanche et non fibreuse, en étant apte à envelopper, en partie, le projectile. Cette enveloppe a pour but de protéger le projectile au moment du tir, en lui évitant de s'écraser sous l'effet de la pression des gaz à l'intérieur du canon de l'arme à feu considérée. De-même, toujours en ayant pour objectif de protéger le projectile au moment du tir, compte-tenu de sa grande déformation résultant de sa matière constitutive, le godet est agencé pour conférer une certaine rigidité au corps (6) au moment du tir.As indicated, the body (6) is housed in the cup (3). According to the invention, the bore of the cup, the bottom of which is hemispherical, receives a protective envelope (5) made of a tight, non-fibrous material, being able to envelop, in part, the projectile. The purpose of this envelope is to protect the projectile at the time of shooting, by preventing it from being crushed under the effect of the pressure of the gases inside the barrel of the firearm considered. Likewise, always with the objective of protecting the projectile at the time of firing, given its large deformation resulting from its constituent material, the bucket is arranged to impart a certain rigidity to the body (6) at the time of firing.

Par exemple, le fond du godet (3) présente des nervures externes radiales (3a) qui délimitent en combinaison avec le corps dudit godet, un bourrelet d'étanchéité (3b).For example, the bottom of the cup (3) has radial external ribs (3a) which, in combination with the body of the said cup, define a sealing bead (3b).

Dans une autre forme de réalisation, le projectile est constitué par un corps sphérique sous forme d'une enveloppe (1) en matériau étanche apte à délimiter un volume interne (1a) susceptible d'être remplie d'un fluide liquide ou pâteux (2). A partir de cette conception, on peut envisager deux variantes de réalisation.In another embodiment, the projectile is constituted by a spherical body in the form of an envelope (1) made of waterproof material capable of delimiting an internal volume (1a) capable of being filled with a liquid or pasty fluid (2 ). From this design, two alternative embodiments can be envisaged.

Dans une première forme de réalisation, l'enveloppe (1) est d'une épaisseur réduite de l'ordre d'un millimètre environ, en étant exécutée dans tout matériau suffisamment élastique et résistant pour ne pas éclater au moment de l'impact, tout en ayant la possibilité de s'écraser et de s'étendre en combinaison avec le fluide (figure 11 ).In a first embodiment, the envelope (1) is of a reduced thickness of the order of about a millimeter, being made of any material which is sufficiently elastic and resistant to not burst at the time of impact, while being able to crash and expand in combination with the fluid (Figure 11).

Dans une autre forme de réalisation, l'enveloppe (1) du projectile est réalisée dans un matériau sélectionné pour éclater au moment de l'impact, pour provoquer, d'une manière concomitante, la diffusion du fluide (figure 6). Dans cette forme de réalisation, l'enveloppe (1) est logée dans un étui (4) en deux parties distinctes (4a) et (4b). Comme dans la réalisation précédente, le fond de l'étui présente des nervures externes radiales (4c) conformées pour délimiter un bourrelet d'étanchéité (4d).In another embodiment, the envelope (1) of the projectile is made of a material selected to burst on impact, to cause, concomitantly, the diffusion of the fluid (Figure 6). In this embodiment, the envelope (1) is housed in a case (4) in two separate parts (4a) and (4b). As in the previous embodiment, the bottom of the case has radial external ribs (4c) shaped to delimit a sealing bead (4d).

A noter que dans ces deux formes de réalisation du projectile, le remplissage de l'enveloppe peut s'effectuer de différentes façons. Par exemple, on peut pratiquer dans l'enveloppe (1), un trou pour le remplissage du volume interne par le fluide liquide choisi, puis on pratique toute opération, telle que soudure pour reboucher ce trou.Note that in these two embodiments of the projectile, the envelope can be filled in different ways. By example, one can practice in the envelope (1), a hole for the filling of the internal volume by the chosen liquid fluid, then one carries out any operation, such as welding to fill up this hole.

Quelle que soit la forme de réalisation du projectile, il apparait, compte-tenu de la nature du matériau le constituant (corps sphérique plein en élastomère de polyuréthanne) ou (enveloppe souple remplie d'un liquide), qu'au moment de l'impact du projectile sur l'objectif, ce dernier s'écrase et s'étale, constituant une surface d'impact importante ou bien permet la diffusion du liquide contenu dans l'enveloppe.Whatever the embodiment of the projectile, it appears, taking into account the nature of the material constituting it (spherical body full of polyurethane elastomer) or (flexible envelope filled with a liquid), that at the time of impact of the projectile on the objective, the latter crashes and spreads, constituting a large impact surface or else allows the diffusion of the liquid contained in the envelope.
