Description

PROJECTILE NON POLLUANT POUR -ARME A FEU NON-POLLUTANT PROJECTILE FOR FIREARMS
L'invention concerne un projectile pour arme à feu. Elle s'applique à tous les calibres d'armes de poing et d'infanterie.The invention relates to a projectile for a firearm. It applies to all calibers of handguns and infantry.
Les projectiles classiques comprennent un noyau consti¬ tué en tout ou en partie de plomb et logé à l'intérieur d'une enveloppe métallique.Conventional projectiles comprise a core made up entirely or partly of lead and housed inside a metal casing.
Il est bien connu que le tir soutenu dans les stands de tir, même à l'air libre, produit une concentration anormale de métaux lourds (par exemple baryum et plomb) dans l'air et dans l'environnement de ces zones de tir. Cette concentration de métaux lourds est nuisible à la santé, en particulier à la santé des moniteurs, et elle porte en outre atteinte au système écologique. Une telle situation résulte du dégagement de métaux lourds lors du tir, lequel phénomène a trois origines :It is well known that sustained shooting in shooting ranges, even in the open air, produces an abnormal concentration of heavy metals (for example barium and lead) in the air and in the environment of these shooting areas. This concentration of heavy metals is harmful to health, in particular the health of monitors, and it also damages the ecological system. Such a situation results from the release of heavy metals during firing, which phenomenon has three origins:
1) les résidus de l'amorce expulsés dans l'air; 2) la perte de plomb du noyau sur la trajectoire du projectile, due à l'échauffement et l'arrachement méca¬ nique produit par les gas propulseurs, dans le canon; 3) la fragmentation du projectile dans la cible ou les protections du stand (piège à balles ou murs) .1) residues of the primer expelled into the air; 2) the loss of lead from the nucleus on the trajectory of the projectile, due to the heating and the mechanical tearing produced by the propellants, in the barrel; 3) the fragmentation of the projectile in the target or the protections of the stand (bullet trap or walls).
Des munitions d'entraînement sans métaux lourds sont commercialisées par plusieurs fabricants. Elles permet¬ tent de réduire la pollution par les résidus de l'amor¬ ce. Cependant ces munitions d'entraînement ne reprodui- sent pas des conditions de tir réelles car leur masse insuffisante ne permet pas de faire fonctionner l'arme comme avec des munitions de service, ce qui est préju¬ diciable à l'efficacité de l'entraînement.Heavy metal-free training ammunition is sold by several manufacturers. They make it possible to reduce pollution by residues of the primer. However, these training munitions do not reproduce real shooting conditions because their mass insufficient does not allow to operate the weapon as with service ammunition, which is detrimental to the effectiveness of training.
L'invention a pour objet un projectile ne contenant pas de métaux lourds, qui réduit ou supprime l'émission d'autres métaux dans les zones de tir, et qui reproduit les conditions de tir réelles comme avec des munitions de service classiques.The subject of the invention is a projectile not containing heavy metals, which reduces or eliminates the emission of other metals into the firing zones, and which reproduces the actual firing conditions as with conventional service ammunition.
Ces objectifs sont atteints grâce à l'invention par un projectile tel que défini dans les revendications.These objectives are achieved thanks to the invention by a projectile as defined in the claims.
L'avantage majeur du projectile suivant l'invention est qu'il constitue une munition d'entraînement non pol¬ luante qui garde à l'arme un fonctionnement normal et de qui permet conserver de bonnes propriétés balisti¬ ques compatibles avec les chargements standards, en particulier le maintien d'une impulsion de recul, assu- rant ainsi un entraînement efficace. Un avantage sup- lémentaire est que le projectile suivant l'invention peut être fabriqué en utilisant les machines existan¬ tes.The major advantage of the projectile according to the invention is that it constitutes a non-polishing drive ammunition which keeps the weapon in normal operation and which makes it possible to retain good ballistic properties compatible with standard loads, in particular the maintenance of a reversing impulse, thus ensuring an effective training. An additional advantage is that the projectile according to the invention can be manufactured using existing machines.
L'invention est exposée dans ce qui suit à l'aide des dessins joints.The invention is set out in the following with the aid of the accompanying drawings.
La figure 1 représente une coupe dans un projectile classique. La figure 2 représente, en coupe, un exemple de mode d'exécution d'un projectile suivant l'invention.Figure 1 shows a section through a conventional projectile. FIG. 2 represents, in section, an example of an embodiment of a projectile according to the invention.
Se reportant à la figure 1, un projectile classique comprend une enveloppe métallique 1, en laiton par exemple, renfermant un noyau 2 constitué en tout ou en partie de plomb.Referring to FIG. 1, a conventional projectile comprises a metal casing 1, made of brass for example, enclosing a core 2 made up wholly or in part of lead.
Dans un projectile suivant l'invention, par contre, dont un mode d'exécution est représenté en figure 2, le noyau il est constitué d'un mélange, amalgame, alliage ou autre, d'au moins deux matières, par exemple une ma¬ tière plastique ou un métal léger, chargé de poussiè¬ res, de grains ou autres, de matériau plus lourd tel que fer. Une enveloppe 12 entoure complètement ou par- tiellement le noyau afin d'assurer un bon fonctionne¬ ment dans le canon et une cohésion suffisante du pro¬ jectile en cible.In a projectile according to the invention, on the other hand, an embodiment of which is represented in FIG. 2, the core it consists of a mixture, amalgam, alloy or other, of at least two materials, for example a ma ¬ plastic or a light metal, loaded with dust, grains or other, heavier material such as iron. An envelope 12 completely or partially surrounds the core in order to ensure proper functioning in the barrel and sufficient cohesion of the target projectile.
L'enveloppe peut être métallique (par exemple en lai- ton) et être solidarisée au noyau par un moyen connu quelconque, par exemple par déformation mécanique, pla¬ cage électrolytique ou autres. L'enveloppe peut égale¬ ment être constituée d'une matière organique chargée ou non pour en améliorer les propriétés mécaniques, et solidarisée au noyau par un moyen connu quelconque, par exemple par assemblage, pistolage, trempage ou autres.The envelope may be metallic (for example in brass) and be secured to the core by any known means, for example by mechanical deformation, electrolytic cage or the like. The envelope may also consist of an organic material charged or not to improve the mechanical properties, and secured to the core by any known means, for example by assembly, spraying, soaking or others.
La construction d'un tel projectile doit respecter cer¬ taines conditions :The construction of such a projectile must respect certain conditions:
- le pourcentage de charge en métal doit être compati¬ ble avec une masse minimum assurant le fonctionnement des armes,the percentage of metal charge must be compatible with a minimum mass ensuring the functioning of the weapons,
- la construction de l'enveloppe doit assurer la cohé- sion de l'ensemble et le bon fonctionnement lors de la phase de balistique intérieure (entre autres, prise des rayures assurant la rotation du projectile) .- the construction of the envelope must ensure the cohesion of the whole and the proper functioning during the interior ballistic phase (inter alia, taking of the scratches ensuring the rotation of the projectile).
D'autre part, pour assurer un entraînement efficace, le fonctionnement normal des armes doit être maintenu. En première approche, le fonctionnement automatique ou semi-automatique des armes dépend du maintien d'une impulsion.On the other hand, to ensure effective training, the normal functioning of weapons must be maintained. In first approach, the automatic or semi-automatic functioning of weapons depends on the maintenance of an impulse.
Ir = Vo (m + fc)Ir = Vo (m + fc)
où Ir = impulsion de recul Vo = vitesse à la bouche m = masse projectile fc = fonction de la charge (masse de poudre) .where Ir = reversing pulse Vo = speed at the mouth m = projectile mass fc = function of the charge (mass of powder).
La construction de projectiles conformément à l'inven¬ tion permet de tenir compte de ces facteurs.The construction of projectiles in accordance with the invention makes it possible to take these factors into account.
A titre d'exemple, nullement limitatif, dans un calibre 9 x 19 mm, un noyau en polyethylene chargé de 50 % en volume (soit 80 % en masse) de particules de fer, placé dans une enveloppe de laiton, donne une masse totale de la balle de ± 5 g, qui assure, lorsqu'elle est propul- sée à une vitesse correcte et réalisable, un bon fonc¬ tionnement des armes prévues pour ce calibre. Ce noyau pourrait être facilement réalisé par extrusion d'un barreau, découpé en lopins, ceux-ci étant frappés en¬ suite dans l'enveloppe.By way of example, in no way limiting, in a 9 x 19 mm caliber, a polyethylene core loaded with 50% by volume (i.e. 80% by mass) of iron particles, placed in a brass envelope, gives a total mass of the bullet of ± 5 g, which ensures, when it is propelled at a correct and achievable speed, good functioning of the weapons provided for this caliber. This core could be easily produced by extruding a bar, cut into pieces, which are then struck in the envelope.
Un autre mode de production consiste en une injection de l'amalgame matière plastique - fer directement dans l'enveloppe.Another production method consists of injecting the amalgam of plastic material - iron directly into the envelope.
Ces exemples sont donnés à titre non limitatif pour illustrer des modes de fabrication compatibles avec les installations de cartoucherie actuelles.These examples are given without limitation to illustrate manufacturing methods compatible with current cartridge factory.
Il est évident que l'invention n'est nullement limitée aux exemples et illustrations présentées. De nombreuses modifications pourraient y être apportées, sans sortir du cadre de l'invention : par exemple, le noyau et/ou l'enveloppe pourraient être constitués de plusieurs pièces montées et solidarisées d'une manière quelcon¬ que. It is obvious that the invention is in no way limited to the examples and illustrations presented. Many modifications could be made thereto, without departing from the scope of the invention: for example, the core and / or the envelope could consist of several parts assembled and secured in any manner.
