Description

L'invention est relative aux projectiles perfo­rants comportant,
un projectile principal au calibre de l'arme et dans lequel est ménagé au moins un alésage axial ouvert vers l'avant,
et, logé dans ledit alésage, un projectile auxiliaire au calibre dudit alésage,
une charge propulsive étant disposée entre le fond de cet alésage et ledit projectile auxiliaire.
Un dispositif de déclenchement est prévu pour mettre à feu la charge propulsive en vue de provoquer le tir du projectile auxiliaire avant ou au moment de l'impact du projectile principal sur son but.The invention relates to piercing projectiles comprising,
a main projectile of the caliber of the weapon and in which is provided at least one axial bore open towards the front,
and, housed in said bore, an auxiliary projectile with the caliber of said bore,
a propellant charge being disposed between the bottom of this bore and said auxiliary projectile.
A triggering device is provided for igniting the propellant charge in order to cause the firing of the auxiliary projectile before or at the time of the impact of the main projectile on its aim.

De tels projectiles perforants dont l'effet perforant est donc provoqué, d'une part par le projec­tile auxiliaire et d'autre part par le projectile prin­cipal, sont connus et l'invention a pour but de leur conférer des propriétés destructrices supplémentaires, notamment en ce qui concerne des effets explosifs et/ou incendiaires.Such piercing projectiles, the piercing effect of which is therefore caused, on the one hand by the auxiliary projectile and on the other hand by the main projectile, are known and the invention aims to give them additional destructive properties, in particular by with regard to explosive and / or incendiary effects.

A cet effet, le projectile principal comporte au moins une charge explosive et/ou incendiaire située dans le projectile principal en avant du projectile auxi­liaire avant son tir, des moyens de mise à feu de cette charge explosive et/ou incendiaire étant prévus et agen­cés pour se déclencher automatiquement dès que le pro­jectile auxiliaire a été tiré.To this end, the main projectile comprises at least one explosive and / or incendiary charge located in the main projectile in front of the auxiliary projectile before its firing, means for igniting this explosive and / or incendiary charge being provided and arranged for trigger automatically as soon as the auxiliary projectile has been fired.

Selon un mode de réalisation avantageux de l'in­vention, ces moyens de mise à feu de la charge explosive et/ou incendiaire sont sensibles au passage du projec­tile auxiliaire dans l'alésage axial ménagé dans le projectile principal.According to an advantageous embodiment of the invention, these means for igniting the explosive and / or incendiary charge are sensitive to the passage of the auxiliary projectile in the axial bore formed in the main projectile.

De tels moyens de mise à feu peuvent alors être constitués par au moins un canal reliant l'alésage axial ménagé dans le projectile principal à la charge explo­sive et/ou incendiaire.Such firing means can then be constituted by at least one channel connecting the axial bore formed in the main projectile with an explosive and / or incendiary charge.

L'alésage axial peut comporter des rayures dont le pas est tel que la vitesse angulaire engendrée sur le projectile auxiliaire s'ajoute à la vitesse angulaire communiquée par le projectile principal audit projectile auxiliaire.The axial bore may include scratches whose pitch is such that the angular velocity generated on the auxiliary projectile is added to the angular velocity communicated by the main projectile to said auxiliary projectile.

Au point de vue constructif, il est avantageux de prévoir des moyens de solidarisation pour rendre le projectile auxiliaire, avant son tir, solidaire en rota­tion du projectile principal, de tels moyens de solida­risation pouvant être constitués par un emmanchement conique autoserrant.From a constructive point of view, it is advantageous to provide securing means to make the auxiliary projectile, before firing, integral in rotation with the main projectile, such securing means may be constituted by a self-tightening conical fitting.

Cet emmanchement conique autoserrant entre le projectile auxiliaire et le projectile principal joue également le rôle de moyen de retenue temporaire du projectile auxiliaire dans l'alésage axial et permet une optimisation de la mise en vitesse (vitesse axiale et vitesse de rotation) du projectile auxiliaire lors de la mise à feu de la charge propulsive.This self-locking conical fitting between the auxiliary projectile and the main projectile also plays the role of temporary retention means of the auxiliary projectile in the axial bore and allows an optimization of the setting in speed (axial speed and rotational speed) of the auxiliary projectile during firing of the propellant charge.

L'invention consiste, mises à part les disposi­tions dont il vient d'être question, en certaines dispo­sitions qui s'utilisent de préférence en même temps et qui seront plus explicitement décrites ci-après.The invention consists, apart from the arrangements just mentioned, of certain arrangements which are preferably used at the same time and which will be more explicitly described below.

L'invention pourra de toute façon être bien comprise à l'aide du complément de description qui suit ainsi que du dessin ci-annexé, lesquels complément et dessin sont relatifs à un mode de réalisation préféré de l'invention et ne comportent bien entendu aucun carac­tère limitatif.

  • La figure 1 de ce dessin est une vue en coupe axiale d'un projectile établi conformément à l'inven­tion.
  • La figure 2 est une coupe selon la ligne II-II de la figure 1.
The invention may in any case be well understood with the aid of the additional description which follows as well as of the appended drawing, which supplement and drawing relate to a preferred embodiment of the invention and of course do not include any limiting character.
  • Figure 1 of this drawing is an axial sectional view of a projectile established in accordance with the invention.
  • Figure 2 is a section along line II-II of Figure 1.

Le projectile perforant conforme à l'invention peut être réalisé dans des calibres tels que le calibre de 12,7 mm (.50) qui est celui de la plupart des mi­trailleuses actuellement en service.The penetrating projectile according to the invention can be produced in calibers such as the 12.7 mm (.50) caliber which is that of most machine guns currently in service.

Cependant, il est tout à fait possible d'envi­sager l'application de l'invention à d'autres calibres, notamment les calibres 15 mm, 20 mm, 25 mm, 30 mm, 35 mm, 40 mm, voire même supérieurs.However, it is entirely possible to envisage the application of the invention to other calibers, in particular the calibers 15 mm, 20 mm, 25 mm, 30 mm, 35 mm, 40 mm, or even higher.

Le projectile perforant comporte :
    - un projectile principal 1 réalisé au moins en partie en un matériau dur (acier), ce projectile princi­pal étant au calibre de l'arme, un alésage axial 2 ouvert vers l'avant étant ménagé dans ce projectile principal, coaxialement à son axe de symétrie axial,
    - et, logé dans cet alésage axial 2, un projec­tile auxiliaire 3 réalisé essentiellement en matériau dur (acier), ce projectile auxiliaire étant au calibre dudit alésage 2, une charge propulsive 4 étant disposée entre le fond de cet alésage 2 et ledit projectile auxi­liaire 3.The penetrating projectile includes:
a main projectile 1 made at least in part from a hard material (steel), this main projectile being of the caliber of the weapon, an axial bore 2 open towards the front being formed in this main projectile, coaxial with its axis of axial symmetry,
- And, housed in this axial bore 2, an auxiliary projectile 3 made essentially of hard material (steel), this auxiliary projectile being of the caliber of said bore 2, a propellant charge 4 being disposed between the bottom of this bore 2 and said auxiliary projectile 3.

Un dispositif de déclenchement, désigné d'une façon générale par le chiffre de référence 5 et dont il sera plus explicitement question ci-après, est prévu pour mettre à feu la charge propulsive 4 en vue de pro­voquer le tir du projectile auxiliaire 3 avant ou au moment de l'impact du projectile principal 1 sur son but.A triggering device, generally designated by the reference numeral 5 and which will be more explicitly discussed below, is provided for igniting the propellant charge 4 in order to cause the firing of the auxiliary projectile 3 before or at the time of impact of the main projectile 1 on its goal.

Ce projectile principal 1 est avantageusement réalisé en plusieurs parties, à savoir
    - un noyau central 6 constitué en un matériau dur (acier), ou à la fois dur et lourd (tungstène), ce noyau central comportant une partie arrière 6a tronco­nique dont le diamètre diminue vers l'arrière et une partie avant 6b tronconique dont le diamètre diminue vers l'avant,
    - un sabot arrière 7 constitué en matériau moins dur que l'acier (laiton) et présentant un alésage tron­conique 7a propre à s'emmancher sur la partie arrière tronconique 6a du noyau central 6, ce sabot arrière 7 comportant une zone en renflement annulaire 7b dont le diamètre extérieur est tel qu'il coopère avec les rayures du canon par lequel le projectile selon l'inven­tion est tiré,
    - une coiffe avant 8 réalisée en matériau moins dur que l'acier (laiton) et présentant un alésage tron­conique 8a propre à s'emmancher sur la partie avant tronconique 6b du noyau central 6, cette coiffe avant 8 comportant une zone en renflement annulaire 8b dont le diamètre extérieur est tel qu'il coopère avec les rayures du canon par lequel le projectile selon l'inven­tion est tiré.This main projectile 1 is advantageously produced in several parts, namely
a central core 6 made of a hard material (steel), or both hard and heavy (tungsten), this central core comprising a rear part 6 a frustoconical whose diameter decreases towards the rear and a front part 6 b frustoconical whose diameter decreases towards the front,
- a rear shoe 7 consisting of less hard material than steel (brass) and having a frustoconical bore 7 is adapted to fit over the tapered rear portion 6a of the core 6, the rear shoe 7 having a bulge area annular 7 b whose outside diameter is such that it cooperates with the scratches of the barrel by which the projectile according to the invention is fired,
- a front cover 8 made of less hard material than steel (brass) and having a frustoconical bore 8 is adapted to fit over the front tapered part 6b of the central core 6, this front cover 8 having a bulge area annular 8 b whose external diameter is such that it cooperates with the scratches of the barrel by which the projectile according to the invention is fired.

Le susdit sabot arrière 7 et la susdite coiffe avant 8 se raccordent entre eux au niveau d'un plan de jonction P, le diamètre extérieur du projectile selon l'invention au niveau de ce plan de jonction P étant inférieur au diamètre extérieur du sabot arrière 7 au niveau de sa zone en renflement annulaire 7b et au dia­mètre extérieur de la coiffe avant 8 au niveau de sa zone en renflement annulaire 8b, et ce dans des propor­tions telles que le creux reliant les deux susdites zones en renflement annulaires ne soient pas en contact avec le canon par lequel le projectile selon l'invention est tiré.The aforesaid rear shoe 7 and the above front cover 8 are connected to each other at a junction plane P, the outside diameter of the projectile according to the invention at this junction plane P being less than the outside diameter of the rear shoe 7 at its area annular bulge 7b and the outer diameter of the front cover 8 at its annular bulge area 8b, and this in such proportions that the hollow connecting said two zones annular bulge are not in contact with the barrel by which the projectile according to the invention is fired.

L'alésage axial 2 d'un tel projectile est donc ménagé dans le noyau central 6 qui présente à son avant une bouche 9 recouverte par la pointe 10 de la coiffe avant 8 qui, au niveau de cette bouche 9, présente une faible épaisseur.The axial bore 2 of such a projectile is therefore formed in the central core 6 which has at its front a mouth 9 covered by the tip 10 of the front cap 8 which, at this mouth 9, has a small thickness.

Pour conférer à un tel projectile des propriétés destructrices, notamment en ce qui concerne des effets explosifs et/ou incendiaires, le projectile principal 1 comporte une ou de préférence plusieurs charges explo­sives et/ou incendiaires 11 situées dans le projectile principal 1, en avant du projectile auxiliaire 3 avant son tir, des moyens de mise à feu de cette charge explo­sive et/ou incendiaire 11 désignés d'une façon générale par le chiffre de référence 12 étant prévus et agencés pour se déclencher automatiquement dès que le projectile auxiliaire 3 a été tiré.To give such a projectile destructive properties, in particular with regard to explosive and / or incendiary effects, the main projectile 1 comprises one or preferably several explosive and / or incendiary charges 11 located in the main projectile 1, in front of the auxiliary projectile 3 before firing, means for igniting this explosive and / or incendiary charge 11 designated in a way general by the reference numeral 12 being provided and arranged to fire automatically as soon as the auxiliary projectile 3 has been fired.

Il est avantageux de disposer ces charges explo­sives et/ou incendiaires 11 entre le noyau central 6 et la coiffe avant 8.It is advantageous to have these explosive and / or incendiary charges 11 between the central core 6 and the front cover 8.

A cet effet, il est prévu des logements 13 régu­lièrement espacés circonférentiellement, et ménagés dans le noyau central 6, chacun de ces logements 13 renfer­mant une substance explosive et/ou incendiaire et se trouvant fermé par la paroi intérieure de la coiffe avant 8.To this end, recesses 13 are regularly spaced circumferentially, and formed in the central core 6, each of these recesses 13 containing an explosive and / or incendiary substance and being closed by the inner wall of the front cover 8.

Les moyens de mise à feu 12 de ces charges ex­plosives et/ou incendiaires 11 sont avantageusement réa­lisés de façon à être sensibles au passage du projectile auxiliaire 3 dans l'alésage 2.The means 12 for firing these explosive and / or incendiary charges 11 are advantageously produced so as to be sensitive to the passage of the auxiliary projectile 3 in the bore 2.

Dans ces conditions, il est prévu au moins un canal 14 reliant l'alésage axial 2 à chaque charge explosive et/ou incendiaire 11 abritée dans son logement 13.Under these conditions, at least one channel 14 is provided connecting the axial bore 2 to each explosive and / or incendiary charge 11 housed in its housing 13.

La mise à feu de la charge propulsive 4 provoque le tir du projectile auxiliaire 3 et, dès que ce projec­tile auxiliaire 3 a dépassé le débouché des canaux 14 dans l'alésage 2, les gaz chauds pénètrent dans les ca­naux 14 et mettent à feu les charges explosives et/ou incendiaires abritées dans les logements 13.The firing of the propellant charge 4 causes the auxiliary projectile 3 to fire and, as soon as this auxiliary projectile 3 has passed the outlet of the channels 14 in the bore 2, the hot gases penetrate the channels 14 and ignite the Explosive and / or incendiary charges housed in the accommodation 13.

L'alésage axial 2 peut comporter des rayures 15 dont le pas est tel que la vitesse angulaire engendrée sur le projectile auxiliaire 3 s'ajoute à la vitesse angulaire communiquée par le projectile principal 1 audit projectile auxiliaire 3.The axial bore 2 may include scratches 15 whose pitch is such that the angular speed generated on the auxiliary projectile 3 is added to the angular speed communicated by the main projectile 1 to said auxiliary projectile 3.

Il est avantageux de prévoir des moyens de solidarisation pour rendre le projectile auxiliaire 3, avant son tir, solidaire en rotation du noyau central 6 du projectile principal 1 ; de tels moyens sont consti­tués par emmenchement conique autoserrant 16 entre la partie arrière du projectile auxiliaire 3 et le fond de l'alésage axial 2 et ménagés dans le noyau central 6.It is advantageous to provide securing means to make the auxiliary projectile 3, before firing, integral in rotation with the central core 6 of the main projectile 1; such means are formed by self-locking conical engagement 16 between the rear part of the auxiliary projectile 3 and the bottom of the axial bore 2 and formed in the central core 6.

Cet emmenchement conique autoserrant 16 entre le projectile auxiliaire 3 et le noyau central 6 joue éga­lement le rôle de moyens de retenue temporaire du pro­jectile auxiliaire 3 dans l'alésage axial 2 et permet une optimisation de la mise en vitesse (vitesse axiale et vitesse de rotation) du projectile auxiliaire 3 lors de la mise à feu de la charge propulsive.This self-locking conical engagement 16 between the auxiliary projectile 3 and the central core 6 also plays the role of temporary retaining means of the auxiliary projectile 3 in the axial bore 2 and allows an optimization of the speed setting (axial speed and rotational speed ) of the auxiliary projectile 3 when the propellant charge is fired.

Pour augmenter le volume de la charge propulsive 4, il peut être avantageux de prévoir une zone 2a de diamètre agrandi au fond de l'alésage axial 2.To increase the volume of the propellant charge 4, it may be advantageous to provide an area 2 a of enlarged diameter at the bottom of the axial bore 2.

Le dispositif de déclenchement 5, prévu pour mettre à feu la charge propulsive 4 en vue de provoquer le tir du projectile auxiliaire 3, peut comporter
    - une fusée détonatrice de proximité 17 disposée à l'avant du projectile, par exemple entre la pointe 10 de la coiffe avant 8 et la bouche 9 par laquelle l'alé­sage axial 2 débouche du noyau central 6,
    - et un ou de préférence plusieurs conduits 18, contenant une substance pyrotechnique et reliant cette fusée détonatrice de proximité 17 à la charge propulsive 4, ces conduits 18 pouvant être ménagés entre le noyau central 6 d'une part, et le sabot arrière 7 et la coiffe avant 8 d'autre part.The triggering device 5, designed to ignite the propellant charge 4 in order to cause the firing of the auxiliary projectile 3, may include
a proximity detonating rocket 17 placed at the front of the projectile, for example between the tip 10 of the front cap 8 and the mouth 9 through which the axial bore 2 opens out from the central core 6,
- And one or preferably several conduits 18, containing a pyrotechnic substance and connecting this proximity detonator rocket 17 to the propellant charge 4, these conduits 18 being able to be formed between the central core 6 on the one hand, and the rear shoe 7 and the front cover 8 on the other hand.

Au point de vue constructif, on peut indiquer qu'un projectile conforme à l'invention peut être réali­sé dans tous les calibres.From a constructive point of view, it may be indicated that a projectile in accordance with the invention can be produced in all calibers.

Toutefois, on conçoit que plus le calibre est petit, plus la difficulté de réalisation est grande.However, it is understood that the smaller the caliber, the greater the difficulty of production.

Il est donc raisonnable d'estimer que, pour ob­tenir une réalisation compatible avec une fabrication en grande série à des coûts non prohibitifs, tout calibre inférieur au calibre 12,7 mm (.50), sans être exclu du domaine d'application de l'invention, peut être écarté au moins dans un premier stade.It is therefore reasonable to estimate that, in order to obtain an embodiment compatible with mass production at non-prohibitive costs, any caliber less than the 12.7 mm (.50) caliber, without being excluded from the field of application of the invention can be ruled out at least in the first stage.

Dans le calibre 12,7 mm (.50), il est possible d'adopter une réalisation voisine de celle illustrée sur le dessin annexé : il en serait de même que pour un calibre de 15 mm.In the 12.7 mm (.50) caliber, it is possible to adopt an embodiment similar to that illustrated in the appended drawing: it would be the same as for a 15 mm caliber.

Pour des calibres supérieurs de 20 mm, 25 mm, 30 mm, 35 mm, 40 mm, 50 mm et plus, l'architecture du projectile conforme à l'invention pourrait être conçue plus librement vu les dimensions qu'il serait alors possible de donner aux constituants du projectile.For calibers greater than 20 mm, 25 mm, 30 mm, 35 mm, 40 mm, 50 mm and more, the architecture of the projectile in accordance with the invention could be designed more freely given the dimensions that it would then be possible to give to the constituents of the projectile.

Comme il va de soi et comme il résulte d'ail­leurs déjà de ce qui précède, l'invention ne se limite nullement à ceux de ses modes d'application et de réa­lisation qui ont été plus particulièrement envisagés ; elle en embrasse, au contraire, toutes les variantes.As goes without saying and as it already follows from the above, the invention is in no way limited to those of its modes of application and embodiments which have been more particularly envisaged; on the contrary, it embraces all its variants.
