Abstract
Description
L'objet de l'invention consiste en un premier certificat d'addition au brevet français N" 2.442.427 déposé le 24 Novenibre 1978, pour un dispositif de projectile mono-pièce, lancé par arme portative. The subject of the invention consists of a first certificate of addition to French patent N "2,442,427 filed on 24 Novenibre 1978, for a one-piece projectile device, launched by portable weapon.
Il est destiné à l'amélioration balistique du projectile pour fusils de chasse à canon lisse, choké ou non en ce qui concerne l'équilibrage et la stabilisation de la balle ainsi que sa pénétration et précision. It is intended for ballistic improvement of the projectile for shotguns with smooth barrel, choké or not with regard to the balancing and stabilization of the bullet as well as its penetration and precision.
L'expérience a démontré que la partie métallique entourée de métal mou et déformable, de centrage ne constituant pas un empannage directement suffisant pour assurer un effet directionnel donnant au projectile une précision maximale et une pénétration arnéliorée. Experience has shown that the metal part surrounded by soft, deformable, centering metal does not constitute a directly sufficient jibe to ensure a directional effect giving the projectile maximum precision and improved penetration.
Le dispositif supprime ces inconvénients et permet de compléter l'action des ailettes afin de donner au projectile une portée augmentée et une plus grande précision. The device eliminates these drawbacks and makes it possible to complete the action of the fins in order to give the projectile an increased range and greater precision.
Il est constitué par la combinaison du corps de la balle profilée en métal dur, d'abord avec une garniture enveloppante au métal mou avec trois ailettes à 1200, ensuite par un empennage léger, stabilistateur en résine synthérique, à section conique subissant l'intégralité de l'effet de propulsion. It is constituted by the combination of the body of the profiled ball in hard metal, first with an enveloping lining in soft metal with three fins at 1200, then by a light tail, stabilizer in synthetic resin, with conical section undergoing the entirety of the propelling effect.
Sur les dessins annexés, donnés à titre d'exemple non limitatif, d'une des formes de réalisation de l'objet de l'invention
La figure 1 montre la balle vue en élévation et en coupe longitudinale.In the accompanying drawings, given by way of nonlimiting example, of one of the embodiments of the subject of the invention
Figure 1 shows the ball seen in elevation and in longitudinal section.
La figure 2 est une vue en plan du même dispositif. Figure 2 is a plan view of the same device.
La balle, figure 1, est constituée par un noyau en acier 1, formant à sa partie supérieure un évasement tronc conique avec pointe de pénétration axiale 2. The ball, FIG. 1, is constituted by a steel core 1, forming at its upper part a flare conical trunk with axial penetration point 2.
Cette pointe de pénétration 2 se prolonge par un secteur cylindrique 3 de grand diamètre et une tige 4 avec profils d'ancrage 5, 6. This penetration point 2 is extended by a cylindrical sector 3 of large diameter and a rod 4 with anchoring profiles 5, 6.
Le noyau à sa partie supérieure est entouré de métal mou 7 de lestage et déformable, de secteur conique et formant des ailettes 8, 9, 10 recouvrant intégralement l'empennage 11 en matière légère et résistante telle une résine synthétique. The core at its upper part is surrounded by soft metal 7 of ballast and deformable, of conical sector and forming fins 8, 9, 10 completely covering the tail 11 of light and resistant material such as a synthetic resin.
Cet empennage léger est de secteur conique et sa grande base 12 a le diamètre du calibre de l'arme. This light empennage is of conical sector and its large base 12 has the diameter of the gauge of the weapon.
Cette surface plane 12 forme une très large surface de poussée et réalise en même temps un stabilisateur intégré au noyau. This flat surface 12 forms a very large thrust surface and at the same time produces a stabilizer integrated into the core.
Par contre, le rnétal mou déformable avec ses ailettes en étoile à trois branches constitue une élément de centrage et de contact réduit, sans freinage et ne déformant pas le canon de l'arme. On the other hand, the deformable soft metal with its three-pointed star fins constitutes an element of centering and reduced contact, without braking and not deforming the barrel of the weapon.
Par cet ensemble homogène et intégré on supprime les imprécisions de trajectoire et on augmente la portée ainsi que la pénétration du projectile, tout en améliorant les qualités décrites dans le brevet principal. By this homogeneous and integrated assembly we remove the inaccuracies of trajectory and we increase the range as well as the penetration of the projectile, while improving the qualities described in the main patent.
C'est donc bien par la forme fonctionnelle du noyau 1, de l'enveloppe en métal mou 7 et de 1 ' empennage en matière légère et résistante à section conique 11, que se caractérise la présente addition. It is therefore indeed by the functional form of the core 1, of the soft metal casing 7 and of the empennage of light and resistant material with conical section 11, that the present addition is characterized.
Toutefois les dimensions et formes comme d ' ailleurs les matières utilisées pour leur fabrication pourront varier dans la limite des équivalents, sans changer pour cela, la conception générale de l'invention qui vient d'être décrite. However, the dimensions and shapes, as indeed the materials used for their manufacture, may vary within the limit of equivalents, without changing the general conception of the invention which has just been described.
C'est ainsi que l'empannage peut avoir suivant les destinations des profils avec concavités, évidements ou autres. This is how jibe can have, depending on the destinations, profiles with concavities, recesses or others.
