Definitions
- the invention relates to a projectile with low recoil and high stopping power. It applies to any caliber of handgun or infantry.
- the Ec is therefore directly proportional to the mass and to the square of the remaining velocity of the projectile.
- the recoil pulse is therefore directly proportional to the mass and the initial speed of the projectile.
- the projectile according to the invention aims to minimize this contradiction.
- the invention aims to provide a projectile with a high stopping power, the construction of which is such that no deformation or disintegration of the projectile takes place in a soft target.
- the subject of the invention is a low-mass projectile, making it possible to obtain a weak reversing pulse by increasing the stopping power at all distances of use of the ammunition, by a rapid abandonment of its kinetic energy in the target, without deformation or disintegration.
- the projectile according to the invention making it possible to achieve the aforementioned advantages a.a. is characterized by its geometry and in particular the ratio l / d (length on caliber), which will advantageously be greater than 3.
- a projectile according to the invention is characterized in that the proportions of the lengths of the constituent parts of the projectile are: for the warhead, between 1.5 and 3 times the size of the size, for the cylindrical part between 0.7 and 2 times the size of the size and for the rear conical part between 9 and 1 times the size of the size, the l / d ratio (length over the size of the caliber) being located between 3 and 6 and the center of gravity of the projectile being located in said cylindrical part of the projectile.
- the casing 2 is hollow and made of a hard material, for example an alloy of copper, steel or the like.
- the core 3 could consist of two or more pieces mounted one in the extension of the other and possibly joined together in any way.

Abstract
Description
- L'invention concerne un projectile à faible recul et haut pouvoir d'arrêt. Il s'applique à tout calibre d'arme de poing ou d'infanterie.
- Il est bien connu que le pouvoir d'arrêt d'un projectile consiste dans sa faculté de perdre, à partir du moment où il touche la cible, un maximum d'énergie en un minimum de temps.
-
- L'Ec est donc directement proportionelle à la masse et au carré de la vitesse restante du projectile.
- Il est encore connu que le recul d'une munition est néfaste au point de vue de dépointage de l'arme, donc de la précision du coup suivant, de la faculté de tir en rafale et de l'effet psychologique produit sur le tireur.
- La notion de recul est caractérisée par l'impulsion de recul
Ir = Vo (m + 1,75 c)
dans laquelle:
Vo = vitesse à la bouche de l'arme
m = masse du projectile
c = charge de poudre. - L'impulsion de recul est donc directement proportionnelle à la masse et à la vitesse initiale du projectile.
- De ce qui précède résulte qu'il existe une contradiction fondamentale entre une Ec élevée et une Ir faible.
- Le projectile selon l'invention vise à minimiser cette contradiction.
- De plus, l'invention vise à fournir un projectile à pouvoir d'arrêt élevé dont la construction est telle qu'il ne se produit pas de déformation, ni de désintégration du projectile dans une cible molle.
- L'invention a pour objet un projectile de faible masse, permettant d'obtenir une faible impulsion de recul en augmentant le pouvoir d'arrêt à toutes distances d'utilisation de la munition, par un abandon rapide de son énergie cinétique dans la cible, sans déformation ni désintégration.
- Le projectile selon l'invention permettant de réaliser e.a. les susdits avantages est caractérisé par sa géométrie et notamment le rapport l/d (longueur sur calibre), lequel sera avantageusement supérieur à 3.
- Un projectile selon l'invention est caractérisé en ce que les proportions des longueurs des parties constitutives du projectile sont: pour l'ogive, entre 1,5 et 3 fois la dimension du calibre, pour la partie cylindrique entre 0,7 et 2 fois la dimension du calibre et pour la partie conique arrière entre 9 et 1 fois la dimension du calibre, le rapport l/d (longueur sur la dimension du calibre) étant situé entre 3 et 6 et le centre de gravité du projectile étant situé dans ladite partie cylindrique du projectile.
- Par cette configuration du projectile on obtient effectivement une aérodynamique optimale.
- Pour plus de clarté, un mode de réalisation d'un projectile selon l'invention est décrit ci-après à titre illustratif et non restrictif, avec référence aux dessins annexés, dans lesquels:
- la figure 1 représente en coupe longitudinale et en vue explosée les éléments constitutifs d'un projectile selon l'invention;
- la figure 2 représente, également en coupe longitudinale, un projectile selon l'invention;
- la figure 3 représente une variante de la figure 2.
- Comme représenté dans les dessins, le projectile 1 est substantiellement constitué de deux éléments, resepectivement l'enveloppe 2 et le noyau 3.
- L'enveloppe 2 est creuse et réalisée en une matière dure, par exemple un alliage de cuivre, acier ou similaire.
- Le noyau 3 est exécuté en une matière rigide de densité plus faible que l'enveloppe, telle que du plastique à haute densité, par exemple polycarbonate, polyamide ou autre, éventuellement chargé de fibres, billes de verre, ou similaire.
- Le noyau 3 peut être réalisé en une ou plusieures pièces solidarisées ou non l'une à l'autre.
- De cette manière on obtient un projectile donnant un rapport m/s faible.
- La forme du projectile est telle qu'on obtient une aérodynamique optimale permettant de conserver des vitesses restantes élevées nécessaires aux performances recherchées.
- Cette optimisation aérodynamique du projectile, réduisant la chute de vitesse sur la trajectoire, permet d'utiliser une charge de poudre plus faible pour atteindre les vitesses restantes recherchées contribuant aussi à la réduction de l'impulsion de recul.
- Par l'emploi d'un noyau 3 en une matière telle que spécifiée précédemment, on empêche la déformation du projectile dans les cibles molles.
- Par la combinaison d'une enveloppe 2 en une matière dure et d'un noyau 3 en une matière d'une densité plus faible que celle de l'enveloppe 2, c.à.d. plus légère, on obtient un basculement de la balle dans un corps mou par suite de la déstabilisation très rapide d'un tel projectile tout en gardant un pouvoir de pénétration considérable en raison de sa haute vitesse et de sa construction rigide.
- A titre d'exemple non limitatif, pour un type de projectile selon l'invention, en calibre 5,56 mm les caractéristiques seraient:
- masse de 1,5 à 2 g
- rapport l/d: 4,5 +/- 0,5
- l'ogive 4: 2,5 fois le calibre +/- 0,5 fois le calibre;
- la partie cylindrique 5: 1,5 fois le calibre +/- 0,5 fois le calibre;
- le cône arrière 6: 0,5 fois le calibre +/- 0,5 fois le calibre à combiner dans la limite de l/d. - La position du centre de gravité 7 sera comprise entre 0 et 4 mm dans la partie cylindrique 5 à partir du raccordement avec l'ogive 4.
- Il est évident que l'invention n'est nullement limitée aux exemples décrits ci-avant et illustrés dans les dessins. En effet, de nombreuses modifications peuvent y être apportées sans, pour autant, sortir du cadre de l'invention.
- Ainsi, le noyau 3 pourrait être constitué de deux ou plusieurs pièces montées l'une dans le prolongement de l'autre et éventuellement solidarisées mutuellement d'une manière quelconque.
