Description

Cette invention est relative à un système d'arme ou lanceur léger à tube reculant, pour mines ou projectiles antichars, par exemple.This invention relates to a weapon system or light launcher with retracting tube, for mines or anti-tank projectiles, for example.

Les lanceurs légers connus sont généralement basés sur des concepts destinés à minimiser l'impulsion de recul qui leur est appliquée au départ du projectile et les rendre ainsi capables des tirs à partir d'un affût léger, voire à partir de l'épaule.
C'est notamment le cas des lance-roquettes et des canons dits "sans recul". En effet, les roquettes se propulsent elles-mêmes par réaction et, par ailleurs, l'impulsion de recul provoquée par le lancement d'un projectile dans un canon sans recul est compensée par l'éjection en sens inverse, soit de gaz de combustion, soit d'un lest généralement divisé. Des améliorations importantes de ce dernier type de lanceur léger ont été l'object des brevets et demandes de brevet suivantes déposés au nom de la présente titulaire :
- 79 28 780 déposée le 22 Novembre 1979 et publiée sous le n° 2 470 358;
- 82 17 460 déposée le 19 Octobre 1982 et publiée sous le n° 2 534 681;
- 85 06 939 déposée le 7 Mai 1985 et publiée sous le n° 2 581 742;
- 86 10 680 déposée le 23 Juillet 1986 pour "Perfectionnements apportés aux armes ou systèmes lanceurs sans recul, de projectiles".Known light launchers are generally based on concepts intended to minimize the recoil impulse applied to them at the start of the projectile and thus make them capable of firing from a light lookout, or even from the shoulder.
This is particularly the case with rocket launchers and so-called "recoilless" cannons. Indeed, the rockets propel themselves by reaction and, moreover, the recoil impulse caused by the launching of a projectile in a recoilless cannon is compensated by the ejection in the opposite direction, that is to say of combustion gas. , or a ballast generally divided. Significant improvements to the latter type of light launcher have been the subject of the following patents and patent applications filed in the name of this owner:
- 79 28 780 filed on November 22, 1979 and published under the number 2 470 358;
- 82 17 460 filed on October 19, 1982 and published under the number 2 534 681;
- 85 06 939 filed on May 7, 1985 and published under the number 2 581 742;
- 86 10 680 deposited on July 23, 1986 for "Improvements brought to the weapons or systems launchers without recoil, of projectiles".

Cependant, l'adaptation des roquettes aux lanceurs légers suppose généralement l'usage de courtes durées de combustion. Celles-ci impliquent un supplément de coût en rapport avec la difficulté de maîtriser de telles lois de combustion : nécessité d'un propergol à caractéristiques élevées, dont les éléments doient être formés avec une géométrie précise et solidement accrochés à la structure.
Par ailleurs, les canons sans recul connus présentent une masse relativement importante, du fait du supplément de masse correspondant à la compensation du recul.However, the adaptation of rockets to light launchers generally requires the use of short combustion times. These involve an additional cost in connection with the difficulty of mastering such combustion laws: need for a propellant with high characteristics, the elements of which must be formed with a precise geometry and firmly attached to the structure.
Furthermore, the known recoilless guns have a relatively large mass, due to the additional mass corresponding to the compensation for recoil.

C'est pourquoi la présente invention se propose d'apporter un lanceur léger dans lequel on minimise simultanément la masse et le coût du système.This is why the present invention proposes to provide a light launcher in which the mass and the cost of the system are simultaneously minimized.

En conséquence, l'invention concerne une arme ou système d'arme lanceur léger à tube reculant, notamment pour mines ou projectiles antichars qui comprend un affût de pointage ou de prépointage, un tube de lancement fermé à sa partie arrière, un projectile et sa charge de propulsion, caractérisé en ce que ledit tube de lancement est relié audit affût par l'intermédiaire d'un berceau organisé de manière à permettre, après mise à feu de la charge de propulsion, le découplage du tube par rapport au berceau et son recul libre, au moins pendant la partie principale du parcours dudit projectile dans l'âme dudit tube.Consequently, the invention relates to a weapon or system of a light launching weapon with a retracting tube, in particular for mines or anti-tank projectiles which comprises a lookout or foresight mount, a launch tube closed at its rear part, a projectile and its propulsion charge, characterized in that said launching tube is connected to said mounting via a cradle organized so as to allow, after ignition of the propelling charge, the decoupling of the tube relative to the cradle and its free recoil, at least during the main part of the course of said projectile in the core of said tube.

Comme on le comprend, le système d'arme selon l'invention permet d'obtenir un recul du tube de lancement aussi libre que possible en éliminant les réactions d'affût susceptibles de dégrader la précision du tir, le découplage du tube reculant et de l'affût étant réalisé de façon simple et peu coûteuse et la suppression de tout dispositif compensateur du recul permettant de diminuer fortement la masse du lanceur selon l'invention.As will be understood, the weapon system according to the invention makes it possible to obtain a retraction of the launching tube as free as possible by eliminating the mounting reactions liable to degrade the accuracy of the shot, the decoupling of the retreating tube and the lookout being produced in a simple and inexpensive manner and the elimination of any recoil compensating device making it possible to greatly reduce the mass of the launcher according to the invention.

De telles dispositions sont particulièrement bien adaptées au cas des mines ou lanceurs de mines qui doivent être installées en grand nombre sur le terrain sans que la sécurité en arrière du lanceur soit un impératif.Such provisions are particularly well suited to the case of mines or mine launchers which must be installed in large numbers on the ground without safety behind the launcher being an imperative.

Toutefois, et toujours selon l'invention, le tube reculant peut être équipé d'éléments complémentaires capables de freiner ledit tube, après éjection du projectile, et réduire ainsi la portée des effets arrière du système proposé.However, and still according to the invention, the retreating tube can be equipped with additional elements capable of braking said tube, after ejection of the projectile, and thus reducing the range of rear effects of the proposed system.

D'autres caractéristiques et avantages de l'invention ressortiront de la description faite ci-après d'un exemple de réalisation. Il est bien précise qu'il ne s'agit que d'un exemple et que tous autres modes de construction, formes, proportions, dispositions, peuvent également être utilisés sans sortir du cadre de l'invention.Other characteristics and advantages of the invention will emerge from the description given below of an exemplary embodiment. It is very clear that this is only an example and that all other modes of construction, shapes, proportions, arrangements, can also be used without departing from the scope of the invention.

La description de cet exemple de l'invention, de son organisation et de son fonctionnement ressortira mieux de l'examen des dessins sur lesquels :

  • - La figure 1 représente l'ensemble du système d'arme ou lanceur léger à tube reculant objet de l'invention ;
  • - Les figures 2, 3 et 4 précisent les dispositions de montage dudit tube reculant dans son berceau ;
  • - Les figures 5 et 6 présentent des variantes de ce montage.
The description of this example of the invention, of its organization and of its operation will emerge better from the examination of the drawings in which:
  • - Figure 1 shows the entire weapon system or light launcher with recoiling tube object of the invention;
  • - Figures 2, 3 and 4 specify the mounting arrangements of said tube moving back in its cradle;
  • - Figures 5 and 6 show variants of this arrangement.

L'exemple de réalisation illustré par les dessins peut notamment correspondre au cas d'une mine ou d'un système lanceur de mine antichar pointable ou prépointable agissant à distance. En se reportant à la figure 1, on voit que ce système comporte un affût 1, un tube de lancement 2 fermé à la partie arrière et renfermant le projectile ou mine antichar 3, lancé vers la cible par combustion d'une charge propulsive 4, par exemple une masse de propergol, sous l'effet d'un inflammateur 5 et d'un relais d'allumage 6.The exemplary embodiment illustrated by the drawings may in particular correspond to the case of a mine or a pointable or prepointable anti-tank mine launcher system acting at a distance. Referring to FIG. 1, it can be seen that this system comprises a mount 1, a launching tube 2 closed at the rear and containing the anti-tank projectile or mine 3, launched towards the target by combustion of a propellant charge 4, for example a mass of propellant, under the effect of an igniter 5 and an ignition relay 6.

Le tube de lancement 2 est préférentiellement constitué de matériaux composites bobinés sur un insert arrière. Il peut être formé d'un seul ou plusieurs éléments raccordables ou déployables.The launch tube 2 is preferably made of composite materials wound on a rear insert. It can be formed from one or more connectable or deployable elements.

Toujours selon l'invention, et tel qu'illustré par la figure 1, avant le tir et jusqu'au départ du corp, le tube 2 est solidaire de l'affût 1 utilisé pour le pointage ou le prépointage, par l'intermédiaire d'un berceau 7.Still according to the invention, and as illustrated in FIG. 1, before the firing and until the departure of the body, the tube 2 is integral with the carriage 1 used for pointing or prepointing, via d '' a cradle 7.

A cet effet, les bossages sont aménagés sur le tube 2, voire sur le berceau 7 de l'affût dans des sections distinctes, préférentiellement deux sections avant 8 et section arrière 9. De plus, ledit tube est assujetti audit berceau par goupillage : goupilles 10a, 10b ... ou 10 (figure 2) ces goupilles étant cisaillées lors du tir. Pour diminuer l'énergie de ce cisaillement et renforcer le maintien du tube 2 sur le berceau 7 au cours des transports, manipulations et stockage, le système selon l'invention peut comporter des goupilles de renfort amovibles à retirer lors de la mise en place du système.To this end, the bosses are arranged on the tube 2, or even on the cradle 7 of the carriage in separate sections, preferably two front sections 8 and rear section 9. In addition, said tube is secured to said cradle by pinning: pins 10a, 10b ... or 10 (Figure 2) these pins being sheared when fired. To reduce the energy of this shearing and strengthen the retention of the tube 2 on the cradle 7 during transport, handling and storage, the system according to the invention may include removable reinforcing pins to be removed when the system.

Les figures 2, 3 et 4 précisent l'organisation de ces bossages dans le cas d'un premier exemple de réalisation de l'invention.Figures 2, 3 and 4 show the organization of these bosses in the case of a first embodiment of the invention.

Avant tir, chaque bossage du tube tel que 8T est en regard d'un bossage du berceau tel que 8B. Les bossages du tube de lancement 2, tels que 8T et 9T, constituent des tenons encastrés dans les bossages du berceau 7, tels que 8B et 9B, en forme de mortaises ou de chapes. Selon cet exemple de l'invention, ces couples tenon/mortaise sont situés du même côté du tube 2 de lancement et ils sont rainurés de manière à assurer le maintien transversal dudit tube par rapport audit berceau.Before firing, each boss of the tube such as 8T is opposite a boss of the cradle such as 8B. The bosses of the launch tube 2, such as 8T and 9T, constitute studs embedded in the bosses of the cradle 7, such as 8B and 9B, in the form of mortises or yokes. According to this example of the invention, these tenon / mortise pairs are located on the same side of the launching tube 2 and they are grooved so as to ensure the transverse maintenance of said tube relative to said cradle.

Bien entendu, l'invention peut être exploitée avec d'autres dispositions notamment dans la recherche d'une symétrie, par rapport à l'axe xʹx du tube 2, de liaison entre le tube de lancement 2 et le berceau 7 en vue de minimiser les réactions d'affût.Of course, the invention can be used with other arrangements in particular in the search for symmetry, with respect to the axis xʹx of the tube 2, of connection between the launching tube 2 and the cradle 7 in order to minimize lookout reactions.

Ainsi, selon la variante de la figure 5, deux couples de bossages sont disposés en opposition à 180° dans chacune des sections 8 et 9, alors que selon la variante de la figure 6, 3 couples de bossages sont "tiercés" à 120° l'un de l'autre dans chacune desdites sections.Thus, according to the variant of Figure 5, two pairs of bosses are arranged in 180 ° opposition in each of sections 8 and 9, while according to the variant of Figure 6, 3 pairs of bosses are "tiered" at 120 ° from each other in each of said sections.

De plus, pour les trois exemples de réalisation de l'invention objet des figures 2 à 6, les bossages de la section arrière 9 sont décalés par rapport à ceux de la section avant 8 : décalage en orientation ou en écartement par rapport à l'axe xʹx.In addition, for the three embodiments of the invention which are the subject of FIGS. 2 to 6, the bosses of the rear section 9 are offset with respect to those of the front section 8: offset in orientation or in separation with respect to the xʹx axis.

La précision de l'orientation du tube 2 par rapport au berceau 7 dépend de l'écartement des sections de bossage 8 et 9 et de l'ajustement des couples des bossages tels que 8T, 8B ou 9T, 9B.The precision of the orientation of the tube 2 relative to the cradle 7 depends on the spacing of the boss sections 8 and 9 and on the adjustment of the couples of the bosses such as 8T, 8B or 9T, 9B.

A cet effet et selon l'invention, ledit écartement est supérieur au calibre est préférentiellement de l'ordre de 2 à 4 calibres alors que ledit ajustement est préférentiellement "coulissant".To this end and according to the invention, said spacing is greater than the size is preferably of the order of 2 to 4 sizes while said adjustment is preferably "sliding".

Lors du tir et selon l'invention, le tube de lancement 2 est transversalement libre par rapport au berceau 7 dès que sa longueur de recul dépasse une valeur relativement faible, de l'ordre du 1/10ème de calibre par exemple.During the firing and according to the invention, the launching tube 2 is transversely free relative to the cradle 7 as soon as its recoil length exceeds a relatively small value, of the order of 1 / 10th of caliber for example.

A cet effet, la longueur (comptée parallèlement à l'axe xʹx) des bossages du tube 2 de lancement et du berceau 7, tels que 8T et 8B ou tels que 9T et 9B, est préférentiellement de l'ordre du dixième de calibre. Ledit berceau constitue ainsi, vis à vis dudit tube, une "rampe de longueur zero".To this end, the length (counted parallel to the axis xʹx) of the bosses of the launching tube 2 and of the cradle 7, such as 8T and 8B or such as 9T and 9B, is preferably of the order of tenths of a caliber. Said cradle thus constitutes, with respect to said tube, a "zero length ramp".

Etant donné l'organisation du système illustré par ces exemples, on voit que jusqu'au moment du tir, le tube 2 est maintenu par rapport au berceau 7, transversalement au moyen de bossages, longitudinalement au moyen de goupilles : une goupille 10 dans le cas de l'exemple de la figure 2, deux goupilles "opposées" à 180° 10a, 10b dans le cas de la figure 5, trois goupilles "tiercées" à 120° 10c, 10d, 10e dans le cas de l'exemple de la figure 6.Given the organization of the system illustrated by these examples, it can be seen that until the moment of firing, the tube 2 is held relative to the cradle 7, transversely by means of bosses, longitudinally by means of pins: a pin 10 in the in the example of FIG. 2, two pins "opposite" at 180 ° 10a, 10b in the case of FIG. 5, three pins "tiered" at 120 ° 10c, 10d, 10e in the case of the example of Figure 6.

Selon l'invention, lesdites goupilles de cisaillement sont réalisées en alliage léger ou en composite verre-résine, leur section étant définie de manière à assurer la tenue du goupillage vis à vis des épreuves d'environnement de référence comprenant par exemple des chutes, des secousses et des vibrations.According to the invention, said shear pins are made of light alloy or glass-resin composite, their section being defined so as to ensure the holding of the pin against tests. reference environment including, for example, falls, shakes and vibrations.

Etant donné ces dispositions de l'invention, lors de la mise à feu de l'inflammateur 5, puis du relais 6 et de la charge propulsive 4, le tube 2 est soumis à la force de recul exercée par les gaz sur sa partie arrière.Given these provisions of the invention, when igniting the igniter 5, then the relay 6 and the propellant charge 4, the tube 2 is subjected to the recoil force exerted by the gases on its rear part .

Le tube 2 cisaille alors les goupilles telles que 10a et 10b et coulisse dans les surfaces d'appui présentées par des couples de bossages tels que 8T et 8B. Après un parcours de l'ordre du 1/10ème de calibre, ces surfaces d'appui sont entièrement dégagées. Le tube 2 est alors entièrement libre de toute réaction d'affût : les décalages d'orientation ou d'écartement précités entre les bossages des sections 8 et 9 empêchent tout choc ou interaction entre les bossages avant du tube tel que 8T et les bossages arrière de l'affût tel que 9b;The tube 2 then shears the pins such as 10a and 10b and slides in the bearing surfaces presented by pairs of bosses such as 8T and 8B. After a course of the order of 1 / 10th of a caliber, these bearing surfaces are completely free. The tube 2 is then entirely free from any mounting reaction: the aforementioned orientation or spacing offsets between the bosses of sections 8 and 9 prevent any shock or interaction between the front bosses of the tube such as 8T and the rear bosses the lookout such as 9b;

Ainsi, après l'éjection du projectile, ou mine antichar 3 et selon l'invention, le tube 2 est lancé en recul entièrement libre avec une impulsion importante sensiblement égale à la somme de celle du projectile et de celle des gaz de bouche.Thus, after the ejection of the projectile, or anti-tank mine 3 and according to the invention, the tube 2 is launched in completely free recoil with a significant pulse substantially equal to the sum of that of the projectile and that of the mouth gases.

La réduction de la portée des effets arrière peut bien entendu présenter de l'intérêt, y compris dans le cas des systèmes lance-mines.Reducing the range of rear effects can of course be of interest, including in the case of mine-thrower systems.

A cet effet, pour diminuer la vitesse de recul du tube 2, et selon une variante de l'invention, certains équipements tels que dispositifs de pointage ou de détection de la cible sont montés solidairement du tube 2 ; préférentiellement de part et d'autre de l'axe dudit tube de manière à ce que le centre de gravité de la masse reculante demeure au plus près de l'axe xʹx.To this end, to reduce the speed of recoil of the tube 2, and according to a variant of the invention, certain equipment such as pointing or target detection devices are mounted integrally with the tube 2; preferably on either side of the axis of said tube so that the center of gravity of the receding mass remains as close as possible to the axis xʹx.

De plus, le système selon l'invention peut être complété par l'équipement du tube 2 avec des systèmes aérodynamiques, tels que voilures de parachute ou volets aérofreins, capables de se déployer, préférentiellement après éjection du projectile ou mine antichar 3, de manière à diminuer ou dévier fortement, sans perturbation dudit projectile, la vitesse restante du tube 2 pour réduire la portée des effets arrière du système exemple de l'invention.In addition, the system according to the invention can be completed by equipping the tube 2 with aerodynamic systems, such as parachute wings or air brake flaps, capable of deploying, preferably after ejection of the projectile or anti-tank mine 3, of so as to greatly reduce or deviate, without disturbing said projectile, the remaining speed of the tube 2 to reduce the range of rear effects of the example system of the invention.

Selon l'invention, ledit effet de freinage ou de déviation peut aussi être obtenu par une liaison du tube 2 à l'affût 1 ou à son berceau 7 n'intervenant qu'après éjection du projectile 3 : cette liaison étant par exemple effectuée au moyen de sangles ou de câbles.According to the invention, said braking or deflection effect can also be obtained by a connection of the tube 2 to the lookout 1 or to its cradle 7 only intervening after ejection of the projectile 3: this connection being for example made at by means of straps or cables.

Enfin, selon l'invention, le tube 2 peut constituer avec l'affût et son berceau 7, un ensemble "jetable" correspondant au concept dit de "l'arme consommable".Finally, according to the invention, the tube 2 can constitute, with the carriage and its cradle 7, a "disposable" assembly corresponding to the concept known as "the consumable weapon".

Cependant, selon une variante de l'invention, le tube 2 peut encore constituer avec le projectile ou mine antichar 3 ainsi que les éléments pyrotechniques 4, 5 et 6 un "coup complet" capable d'être monté par les utilisateurs eux-mêmes sur le berceau de l'affût 7, ce qui correspond au concept de "l'arme rechargeable".However, according to a variant of the invention, the tube 2 can also constitute with the anti-tank projectile or mine 3 as well as the pyrotechnic elements 4, 5 and 6 a "complete blow" capable of being mounted by the users themselves on the cradle of the lookout 7, which corresponds to the concept of "the rechargeable weapon".

Il demeure bien entendu que la présente invention ne se limite pas aux exemples de réalisation décrits ci-dessus mais qu'elle en englobe toutes les variantes.It remains to be understood that the present invention is not limited to the embodiments described above but that it encompasses all variants thereof.
