Abstract

Projectile-launching weapon system, such as, in particular, an individual infantry weapon, which comprises a propellent charge placed in a container in the form of an unfoldable bag or pouch, and an ejectable divided ballast compensating the recoil momentum, the assembly ensuring the absorption of noise, according to Claim 1 of the main patent, characterised in that the pouch or bag 10 bringing about the launching of the projectile 2 is folded in an arrangement in the form of an overturned "glove finger", and in that said bag/pouch surrounds a pusher piston 12 which alone supports the stresses of the pressure field of the pouch or bag, the projectile thus being safeguarded completely from the direct effects of said pressure field.

Description

Dans son brevet nO 79 28 780, déposé le 22 novembre 1979, la présente titulaire a décrit un système d'arme lançant sans recul un projectile, en utilisant un sac ou poche déployable, ledit sac enfermant la charge propulsive, par exemple du propergol, et maintenant enfermés les gaz de combustion, d'où un lancement sans lueur, avec peu ou pas de bruit, possible à partir d'un local fermé (cas, particulièrement, du combat urbain). In her patent No. 79 28 780, filed on November 22, 1979, the present holder described a weapon system launching a projectile without recoil, using a deployable bag or pocket, said bag enclosing the propellant charge, for example propellant, and now locked up the combustion gases, hence launching without a glow, with little or no noise, possible from a closed room (case, particularly, urban combat).

Ce système de base a été ultérieurement développé et perfectionné dans un autre brevet, n" 82 17 460, déposé le 19 octobre 1982 par la présente titulaire. This basic system was subsequently developed and perfected in another patent, No. 82 17 460, filed on October 19, 1982 by the present owner.

Dans ce dernier brevet, on a proposé, dans la revendication 1, notamment l'emploi d'un,sac-poche,installé en disposition de prédéploiement en "doigt de
retourne gant"l.Le pliage en zig-zag de l'autre extrémité de chaque sac-poche était prevu selon ce meme brevet du 19 octobre 1982,1e nombre de plis étant particulièrement.In this latter patent, it was proposed, in claim 1, in particular the use of a pocket-bag, installed in a pre-deployment arrangement in "finger
returns glove "l. The zig-zag folding of the other end of each pocket bag was provided according to this same patent of October 19, 1982,1 number of folds being particularly.

réduit du côté du lest compensant l'impulsion de recul, alors qu'il était beaucoup plus important du côté du projectile.reduced on the side of the ballast compensating for the impulse of retreat, whereas it was much more important on the side of the projectile.

Ce brevet nO 82 17 460 portait en outre sur la construction d'une culasse centrale à deux chambres ou étages, contenant la charge propulsive en gargousse et comportant les gorges à circlips fixant, de part et d'autre de la culasse, les deux demi-sacs-poches selon l'invention (Revendications 1 et 4 de ce brevet antérieur). This patent No. 82 17 460 also related to the construction of a central cylinder head with two chambers or stages, containing the propellant charge in gargoyle and comprising the grooves with circlips fixing, on either side of the cylinder head, the two half -bags-pockets according to the invention (Claims 1 and 4 of this earlier patent).

L'expérience a montré que, lors de la combustion, les gaz engendrés dans la culasse à deux étages se propagent instantanément et dans de bonnes conditions, dans les dispositifs prédéployés des sacs en "doigt de gant", caractère essentiel du système selon l'invention, qui repose fondamentalement sur le bon remplissage des poches dès l'allumage de la charge et pendant toute la séquence de déploiement. Experience has shown that, during combustion, the gases generated in the two-stage cylinder head propagate instantaneously and under good conditions, in the pre-deployed devices of the "thermowell" bags, an essential character of the system according to the invention, which is fundamentally based on the correct filling of the pockets upon ignition of the load and during the entire deployment sequence.

Il en est tout autrement pour les fractions pliées du sac-poche, en zig-zag par exemple, d'où de nombreuses difficultés de réalisation et de fiabilité. It is quite different for the folded fractions of the pocket-bag, in zig-zag for example, from where many difficulties of realization and reliability.

Celles-ci sont résolues lorsque le nombre de plis est faible, et lorsque le déploiement et le remplissage de ceux-ci se produisent en fin de fonctionnement (sac-poche déjà largement déployé et rempli de gaz, dont la détente a déjà atteint des porportions notables).These are resolved when the number of folds is low, and when the deployment and filling thereof occurs at the end of operation (pocket bag already widely deployed and filled with gas, the expansion of which has already reached portions notable).

C'est ainsi que, côté lest, la disposition décrite à titre d'exemple dans le brevet nO 82 17 460 (Fig. 2, notamment), montre une solution fonctionnant bien et fiable, dans laquelle la partie en "doigt de gant" du sac-poche forme presque tout le volume dudit sac, le pliage en zig-zag de 11 extrémité du sac-poche étant ramené à sa plus simple expression (deux plis tout au plus). Thus, on the ballast side, the arrangement described by way of example in patent No. 82 17 460 (FIG. 2, in particular), shows a solution which works well and is reliable, in which the part as a "thermowell" of the pocket bag forms almost the entire volume of said bag, the zig-zag folding of the end of the pocket bag being reduced to its simplest expression (two folds at most).

te problème est tout différent côté projectile, car il s'agit, dans ce cas, de réaliser un grand volume et une grande longueur de sac-poche, en partie "en doigt de gant", en partie plié en zig-zag ou en "lanterne vénitienne", sans occuper une place excessive dans l'arme, permettant de remplir vite et bien le sac plié, d'être fiable, reproductible, et de ne pas faire supporter au projectile, à sa partie arrière (empennage, propulseur, fusée, D.S.A. ) un champ de contraintes (notamment pression), peu compatible avec un bon bilan de masse, de vitesse, de précision et de fiabilité. the problem is quite different on the projectile side, because in this case it is a question of producing a large volume and a long length of pocket-bag, partly "in a thermowell", partly folded in a zig-zag or in "Venetian lantern", without occupying an excessive place in the weapon, allowing to quickly and well fill the folded bag, to be reliable, reproducible, and not to support the projectile, its rear part (empennage, propellant, rocket, DSA) a stress field (notably pressure), not very compatible with a good balance of mass, speed, precision and reliability.

La présente invention, qui constitue une Addition au brevet n" 82 17 460, apporte une solution optimisée à ce problème, en prévoyant que la poche ou sac renfermant bsgaz de combustion est pliée selon une disposition en "doigt de gant" entourant, côté projectile, un piston-poussoir supportant les contraintes de pression et d'inertie et lançant le projectile (propulseur, empennage, fusée, D.S.A., charge), qui reste tout à fait en dehors de ce champ de contraintes. I1 en résulte une simplification de la construction, plus légère et plus fiable, dudit projectile, alors que le piston-poussoir construit selon l'Addition, de préférence en fibres, tissu, bobiné en KeYlar, verre, aramide, carbone, très cloisonné par conception, est léger et três résistant.On bénéficie ainsi des avantages de bon fonctionnement et de fiabilité du sac-poche en "doigt de gant" entourant ledit piston-poussoir, avec un projectile hors du champ de pression du sac, subissant simplement les effets inertie, comme c'est le cas de tout projectile classique, l'empennage, le propulseur, etc., subissant, sans contrainte spéciale supplémentaire particulière, les efforts normaux d'un proJectile classique, sans qu'on ait à prévoir des dispositions supplémentaires, nécessaires pour supporter le champ de pression du "doigt de gant".  The present invention, which constitutes an addition to patent No. 82 17 460, provides an optimized solution to this problem, by providing that the pocket or bag containing combustion gas is folded in a surrounding "glove finger" arrangement, on the projectile side. , a push-piston supporting the constraints of pressure and inertia and launching the projectile (propellant, tail, rocket, DSA, charge), which remains completely outside this field of constraints. I1 results in a simplification of the construction, lighter and more reliable, of said projectile, while the push-piston built according to the Addition, preferably in fibers, fabric, wound in KeYlar, glass, aramid, carbon, very partitioned by design, is light and very resistant .We thus benefit from the advantages of good functioning and reliability of the pocket bag as a "thermowell" surrounding said push-piston, with a projectile outside the pressure field of the bag, simply undergoing the inertia effects, as is the case. e case of any conventional projectile, the tail, the propellant, etc., undergoing, without any special special constraint, the normal efforts of a conventional projectile, without having to make any additional arrangements necessary to support the field "thimble" pressure.

Cependant, les moyens modernes de construction, les matériaux disponibles, permettent de réaliser un piston-poussoir très résistant et très léger, dont la masse ne présente qu'une faible fraction de la masse du demi sac-poche côté projectile, alors que ce piston-poussoir n'oceupe, sans accroissement significatif de la longueur de l'arme, que la place dévolue à un pliage en zig-zag ou en lanterne vénitienne d'un sac-poche n'utilisant pas le système de piston-poussoir selon l'Addition. However, modern means of construction, the materials available, make it possible to produce a very resistant and very light push-piston, the mass of which presents only a small fraction of the mass of the half-pocket-bag on the projectile side, whereas this piston -pusher only occupies, without significant increase in the length of the weapon, the place allocated to a zig-zag or Venetian lantern folding of a pocket bag not using the piston-pushing system according to the 'Addition.

Les autres caractéristiques et avantages de l'Addition ressortiront de la description faite ci-après, en référence aux dessins annexés, qui en illustrent divers exemples de réalisation non limitatifs. The other characteristics and advantages of the addition will emerge from the description given below, with reference to the appended drawings, which illustrate various non-limiting exemplary embodiments thereof.

Il est bien précisé cependant qu'il s'agit uniquement d'exemples, et que tous autres modes de construction, proportions, formes, matériaux et dispositions peuvent être également utilisés sans sortir du cadre de l'invention. It should be noted, however, that these are only examples, and that all other modes of construction, proportions, shapes, materials and arrangements can also be used without departing from the scope of the invention.

L'exemple d'application se rapporte plus spécialement à une arme individuelle d'infanterie antichar, sans recul, tirable depuis un espace clos, et pour laquelle l'équilibrage dynamique du projectile est assuré par une masse de lest divisé.  The example of application relates more particularly to an individual anti-tank infantry weapon, without recoil, which can be fired from an enclosed space, and for which the dynamic balancing of the projectile is ensured by a mass of divided ballast.

Il est précisé à nouveau .iue l'invention s'applique également, sans sortir de son cadre, à tous missiles, roquettes, obus et projectiles, tirés depuis un tube fermé à l'une des extrémités (canon, mortier, obusier, etc.), ou un tube ouvert aux deux extrémités,
Egalement sans sortir du cadre de l'invention, les sacs ou poches déployables peuvent rester, après tir, dans le tube, ou sortir de ce tube par l'une et/ou l'autre des extrémités.It is specified again. The invention also applies, without departing from its scope, to all missiles, rockets, shells and projectiles, fired from a tube closed at one end (gun, mortar, howitzer, etc. .), or a tube open at both ends,
Also without departing from the scope of the invention, the deployable bags or pockets can remain, after firing, in the tube, or exit from this tube by one and / or the other of the ends.

Sur les dessins annexés
- la Figure t est une vue partielle, en coupe longitudinale selon 1-1 de la Figure 2, de l'ensemble selon l'invention : sac-poche déployable lançant un projectile empenné ; et,
- la Figure 2 est une coupe selon 2.2 de la Figure 1.In the accompanying drawings
- Figure t is a partial view, in longitudinal section along 1-1 of Figure 2, of the assembly according to the invention: deployable pocket bag launching a tailed projectile; and,
- Figure 2 is a section along 2.2 of Figure 1.

Le tube de lancement 1 contient un projectile 2 dont la partie arrière du culot est représentée par la silhouette extérieure 3, portant les ailettes 4 articulées autour d'axes 5. The launching tube 1 contains a projectile 2 the rear part of the base of which is represented by the external silhouette 3, carrying the fins 4 articulated around axes 5.

Dans le cas, fréquent, où le projectile 2 est pourvu d'un propulseur additionnel, celui-ci est logé, par exemple, à l'intérieur du culot 3, sa tuyère 6 étant logée à l'intérieur dudit culot 3, ou, au contraire, en saillie 6' par rapport au culot. In the frequent case where the projectile 2 is provided with an additional propellant, this is housed, for example, inside the base 3, its nozzle 6 being housed inside said base 3, or, on the contrary, projecting 6 'relative to the base.

La silhouette de la culasse centrale 7 de l'arme selon le brevet principal est représentée sur la Figure 1, avec la gargousse 8 contenant la charge propulsive et l'amortisseur 9. En ce qui concerne cette partie de l'arme, on pourra se reporter au brevet principal, dans lequel elle est décrite en détail. The silhouette of the central breech 7 of the weapon according to the main patent is represented in FIG. 1, with the gargoyle 8 containing the propellant charge and the shock absorber 9. With regard to this part of the weapon, it will be possible to refer to the main patent, in which it is described in detail.

Selon l'Addition, le sac-poche 10, assurant le lancement du projectile 2, est prédéployé "en doigt de gant"l et nli est maintenu par des circlips 11 dans la culasse centrale 7 à l'aide d'un embout 18. Ce sac-poche 10 est disposé, sans pliage en zig-zag ou en accordéon, autour d'un piston-poussoir axial 12,
Celui-ci comporte, à l'avant, une cloison 13 formant guidage dans l'arme transmettant la poussée au projectile, sans aucune complication, gene, interférence vis-à-vis de sa construction, ledit projectile étant ainsi entièrement soustrait, selon l'invention, au champ de pression du sac-poche 10, prédéployé en " doigt de gant".According to the Addition, the pocket bag 10, ensuring the launching of the projectile 2, is pre-deployed "in a thimble" 1 and nli is held by circlips 11 in the central breech 7 using a nozzle 18. This pocket bag 10 is arranged, without zig-zag or accordion folding, around an axial push-piston 12,
This comprises, at the front, a partition 13 forming a guide in the weapon transmitting the thrust to the projectile, without any complication, annoyance, interference with respect to its construction, said projectile being thus entirely removed, according to the invention, in the pressure field of the pocket bag 10, pre-deployed as a "thimble".

La construction du piston-poussoir 12 selon l'Addition est à la fois légère et résistante, grâce à l'emploi, de préférence, de fibres aramide "Kevlar", verre, carbone, enconstruction filamentaire, bobiné, tissu tresse, mais l'emploi d'alliage léger résistant est également envisagé, sans sortir du cadre de l'Addition. The construction of the plunger 12 according to the Addition is both light and resistant, thanks to the use, preferably, of aramid "Kevlar" fibers, glass, carbon, filament construction, wound, braided fabric, but the the use of resistant light alloy is also envisaged, without going beyond the scope of the Addition.

La construction dudit piston-poussoir 12 vise une très grande légèreté, mais aussi une grande résistance au flambage, à l'inertie, et au champ de pres sion déployé par le sac-poche, disposé en "doigt de gant" et déployé pendant le fonctionnement. The construction of said push piston 12 aims for a very lightness, but also a great resistance to buckling, to inertia, and to the pressure field deployed by the pocket bag, arranged as a "thermowell" and deployed during the operation.

Ainsi, le piston-poussoir 12 peut comporter, selon l'Addition, des cloisons 14 équipées, éventuellement, de trous d'allègement 15. Il peut aussi comprendre un cylindre axial 16, permettant d'obtenir un ensemble extrêmement résistant à toutes les contraintes supportées par ledit piston-poussoir 12 champs de pression extérieurs, inertie axiale. Thus, the push-piston 12 can comprise, according to the Addition, partitions 14 fitted, possibly, with lightening holes 15. It can also include an axial cylinder 16, making it possible to obtain an assembly extremely resistant to all stresses supported by said push piston 12 external pressure fields, axial inertia.

Dans le cas où la tuyère d'une propulsion additionnelle serait contenue dans le culot 3 du projectile, et que cette tuyère occupe une position extérieure 6', le cylindre axial 16 peut servir, sans surlongueur, à loger ladite tuyère 6'. In the case where the nozzle of an additional propulsion would be contained in the base 3 of the projectile, and this nozzle occupies an external position 6 ′, the axial cylinder 16 can serve, without excess length, to house said nozzle 6 ′.

La face arrière 17 du piston-poussoir 12, éventuellement renforcée par un remplissage 17' à fonctions multiples (raidisseur, amortisseur ) reçoit naturellement la portion 10' du sac-poche 10 prédéployé en "doigt de gant" synthétique
Un coussin 10" (mousse/par exemple) peut éventuellement être interposé entre la portion 10' du sac-poche 10 et la face arrière du piston-poussoir 12. The rear face 17 of the push-piston 12, possibly reinforced by a filling 17 'with multiple functions (stiffener, shock absorber) naturally receives the portion 10' of the pocket bag 10 predeployed as a synthetic "thermowell"
A 10 "cushion (foam / for example) may possibly be interposed between the portion 10 ′ of the pocket bag 10 and the rear face of the push-piston 12.

Le sac-poche 10 étant fixé au tube par le système à circlips 11, porté par la culasse centrale 7, il reste donc lié à l'arme, à la sortie du projectile à la bouche. The pocket bag 10 being fixed to the tube by the circlip system 11, carried by the central breech 7, it therefore remains linked to the weapon, when the projectile leaves the mouth.

Pour que le piston-poussoir 12 ne soit pas éjecté à la bouche et ne crée pas de perturbation au projectile, ledit piston 12 est fixé au sac 10 par tout moyen approprié (non représenté) : par exemple par collage, sertissage, vis, etc.  So that the push piston 12 is not ejected into the mouth and does not create disturbance to the projectile, said piston 12 is fixed to the bag 10 by any suitable means (not shown): for example by gluing, crimping, screws, etc. .
