Description

Objet de l'inventionObject of the invention

Le domaine technologique de l'invention concerne l'intégration d'un support d'interface sur un système canon de différents calibres telle que :

  • ledit support d'interface est dédié à recevoir un système de visée non-spécifique,
  • ledit système canon couvre la gamme des moyens et gros calibres, autrement dit entre 20 mm et 120 mm,
  • ledit système canon est associé à une tourelle montée sur un véhicule blindé quelconque.
The technological field of the invention relates to the integration of an interface support on a gun system of different calibers such as:
  • said interface support is dedicated to receiving a non-specific sighting system,
  • said gun system covers the range of medium and large calibers, in other words between 20 mm and 120 mm,
  • said gun system is associated with a turret mounted on any armored vehicle.

L'invention repose essentiellement sur une approche mécanique.The invention is essentially based on a mechanical approach.

Arrière-plan technologiqueTechnological background

De manière générale, l'insertion d'un (ou d'une combinaison de) système(s) de visée sur une tourelle doit prendre en considération toute une série de paramètres aussi bien fonctionnels que mécaniques.In general, the insertion of a (or a combination of) sighting system (s) on a turret must take into consideration a whole series of parameters, both functional and mechanical.

Parmi ceux-ci, on peut relever :

  • l'encombrement extérieur de la tourelle lié à l'intégration des autres modules tels que lance-missile(s), lance-grenade(s), système de communication (antenne(s), radio(s),...), station météorologique, etc.,
  • le système d'attache,
  • la sensibilité,
  • la précision,
  • les vibrations,
  • les chocs,
  • etc.
Among these, we can note:
  • the external dimensions of the turret linked to the integration of other modules such as missile launcher (s), grenade launcher (s), communication system (antenna (s), radio (s), ...), weather station, etc.,
  • the attachment system,
  • the sensibility,
  • the precision,
  • vibrations,
  • the shocks,
  • etc.

En fonction de ces critères spécifiques, la possibilité d'ajouter un système de visée supplémentaire vis-à-vis de ceux déjà présents sur la tourelle est relativement limitée. Cela est lié au fait que la position de ce dernier ne doit en aucun cas venir perturber fonctionnellement et/ou mécaniquement les modules greffés préalablement.Depending on these specific criteria, the possibility of adding an additional sighting system vis-à-vis those already present on the turret is relatively limited. This is linked to the fact that the position of the latter must in no case functionally and / or mechanically disturb the previously grafted modules.

C'est pourquoi il est indispensable de valoriser un endroit non encore exploité pour satisfaire les nouvelles contraintes contractuelles mais également optimiser économiquement les tourelles développées antérieurement.This is why it is essential to develop a place not yet exploited to meet the new contractual constraints but also to economically optimize the turrets developed previously.

Actuellement, les principales solutions proposées et/ou envisagées reposent sur le fait que le système optique est placé essentiellement sur le masque de la tourelle au niveau duquel i) le mode de fixation n'est pas aussi performant et ii) les chocs et vibrations perçus sont caractérisés par une intensité accrue. A cela s'ajoute le fait que l'encombrement au niveau du masque suite à la présence d'autres modules tels que mitrailleuse coaxiale, système d'éjection de munitions, etc. est tel qu'il n'est pas toujours aisé d'ajouter un élément supplémentaire.Currently, the main solutions proposed and / or envisaged are based on the fact that the optical system is placed essentially on the mask of the turret at which i) the fixing method is not as efficient and ii) the shocks and vibrations perceived are characterized by increased intensity. Added to this is the fact that the size of the mask due to the presence of other modules such as coaxial machine guns, ammunition ejection system, etc. is such that it is not always easy to add an additional element.

Buts de l'inventionAims of the invention

La présente invention a pour but général la mise en place d'une architecture s'inspirant des armes à feu portables, dans lesquelles une lunette de visée est intégrée directement sur le canon de l'arme.The general aim of the present invention is to set up an architecture inspired by portable firearms, in which a sighting telescope is integrated directly on the barrel of the weapon.

Un but complémentaire de l'invention est de développer une structure rigide et interchangeable, appelée support d'interface, caractérisée en ce qu'elle :

  • présente un mode de fixation par vis (approche mécanique),
  • contient un module de visée non-spécifique.
An additional aim of the invention is to develop a rigid and interchangeable structure, called an interface support, characterized in that it:
  • presents a method of fixing by screws (mechanical approach),
  • contains a non-specific aiming module.

L'invention vise également à ne pas limiter la taille du support d'interface par des dimensions précises mais la largeur, la longueur et la hauteur de celui-ci doivent être caractérisées respectivement par des valeurs minimales et maximales, gage d'une certaine flexibilité, qui doit malgré tout rester cohérente avec les contraintes mécaniques et fonctionnelles. De par ces caractéristiques géométriques, la taille du système de visée présente de manière proportionnelle une flexibilité similaire, autrement dit elle est non-spécifique et non-standard pour un seul support d'interface.The invention also aims not to limit the size of the interface support by precise dimensions but the width, length and height of the latter must be characterized respectively by minimum and maximum values, guaranteeing a certain flexibility. , which must nevertheless remain consistent with the mechanical and functional constraints. Due to these geometric characteristics, the size of the sighting system proportionately exhibits a similar flexibility, in other words it is non-specific and non-standard for a single interface medium.

Enfin un but supplémentaire de l'invention est de pouvoir utiliser une tourelle existante sans lui apporter de modification essentielle aux niveaux structurels et fonctionnels tout en garantissant un investissement financier relativement insignifiant ou modéré au regard des bénéfices techniques engendrés par la mise en place du dispositif selon l'invention.Finally, an additional aim of the invention is to be able to use an existing turret without making any essential modification to it at structural and functional levels while guaranteeing a financial investment. relatively insignificant or moderate with regard to the technical benefits generated by the installation of the device according to the invention.

Principaux éléments caractéristiques de l'inventionMain characteristic elements of the invention

Selon l'invention, il est divulgué une tourelle destinée à être montée sur un véhicule blindé, comprenant un système canon couvrant la gamme des moyens et gros calibres, ayant un fourreau de canon et un tube de protection contre les chocs et vibrations, relié au fourreau de canon à la jonction avec le masque de la tourelle, et comprenant un système d'interface, appelé également support d'interface, rigide et interchangeable pour attacher à la tourelle un équipement fonctionnel comportant au moins un système de visée, le système d'interface étant fixé sur ledit tube de protection contre les chocs et vibrations, de sorte que le système d'interface est placé dans un plan perpendiculaire à l'axe longitudinal du système canon.According to the invention, there is disclosed a turret intended to be mounted on an armored vehicle, comprising a gun system covering the range of medium and large caliber, having a barrel sheath and a tube for protection against shocks and vibrations, connected to the gun. gun sheath at the junction with the turret mask, and comprising an interface system, also called interface support, rigid and interchangeable for attaching to the turret functional equipment comprising at least one sighting system, the system of 'interface being fixed on said protective tube against shocks and vibrations, so that the interface system is placed in a plane perpendicular to the longitudinal axis of the gun system.

Selon l'invention, le système d'interface comprend, dans l'ordre prédéfini suivant :

  • une enveloppe essentiellement semi-circulaire ou semi-cylindrique servant de support entourant ledit tube de protection contre les chocs et vibrations,
  • une embase attachée à ladite enveloppe,
  • un plateau surmontant ladite embase et
  • un support fixé perpendiculairement audit plateau.
According to the invention, the interface system comprises, in the following predefined order:
  • an essentially semi-circular or semi-cylindrical envelope serving as a support surrounding said tube for protection against shocks and vibrations,
  • a base attached to said envelope,
  • a plate surmounting said base and
  • a support fixed perpendicularly to said plate.

Le voisinage de la jonction entre le tube de protection relié au fourreau du système canon avec le masque de la tourelle, ces éléments étant bien connus de l'homme de métier, est l'endroit où les chocs et vibrations ressentis par le système canon s'avèrent être de la plus faible intensité lors d'un mouvement quelconque du système canon, ce mouvement étant un déplacement qui est soit vertical, soit horizontal, soit les deux simultanément. L'ensemble des déplacements s'opèrent dans quatre cas de figure spécifiques : i) véhicule et tourelle statiques, ii) véhicule à l'arrêt et tourelle en rotation, iii) véhicule en mouvement et tourelle fixe ainsi que iv) véhicule et tourelle mobiles.The vicinity of the junction between the protection tube connected to the barrel of the gun system with the mask of the turret, these elements being well known to those skilled in the art, is where the shocks and vibrations felt by the gun system s 'prove to be of the lowest intensity during any movement of the gun system, this movement being a movement which is either vertical or horizontal, or both simultaneously. All movements take place in four specific cases: i) static vehicle and turret, ii) stationary vehicle and rotating turret, iii) moving vehicle and fixed turret as well as iv) mobile vehicle and turret .

De par la position du support d'interface, et in fine du système optique, sur le tube de protection du système canon, il en résulte que le système de visée associé est également situé dans le plan vertical (ou perpendiculaire à l'axe longitudinal du système canon).Due to the position of the interface support, and ultimately of the optical system, on the protection tube of the gun system, it follows that the The associated sight is also located in the vertical plane (or perpendicular to the longitudinal axis of the gun system).

Avantageusement, le système de visée aura son axe optique parallèle ou légèrement incliné par rapport à l'axe longitudinal du système canon afin que la cible reste dans le champ de vison du système de visée, ce qui permet de ne plus devoir disposer d'un lien mécanique et/ou électronique entre le système canon et le système de visée.Advantageously, the sighting system will have its optical axis parallel or slightly inclined with respect to the longitudinal axis of the gun system so that the target remains in the field of view of the sighting system, which makes it possible to no longer have to have a mechanical and / or electronic link between the gun system and the sighting system.

En ce qui concerne l'interfaçage entre le support d'interface et le système de visée, il s'effectue avantageusement depuis l'arrière dudit système de visée pour optimiser la solidarisation entre les deux dispositifs.As regards the interfacing between the interface support and the sighting system, it is advantageously carried out from the rear of said sighting system in order to optimize the connection between the two devices.

De préférence encore, l'ensemble des éléments constitués par le tube de protection, l'enveloppe essentiellement semi-circulaire ou semi-cylindrique, l'embase, le plateau et le support sont fixés l'un à l'autre selon l'ordre prédéfini ci-dessus, de préférence encore par un système de vis et/ou boulons (ou vis/écrous). Le système de visée est aussi fixé avantageusement au support du système d'interface par un système de vis et/ou boulons.More preferably, all of the elements constituted by the protection tube, the essentially semi-circular or semi-cylindrical casing, the base, the plate and the support are fixed to each other in the order predefined above, more preferably by a system of screws and / or bolts (or screws / nuts). The sighting system is also advantageously fixed to the support of the interface system by a system of screws and / or bolts.

Le projet développé actuellement permet d'atteindre des niveaux opérationnels, fonctionnels, ergonomiques, économiques, etc. significatifs suite au positionnement défini ci-dessus.The project currently developed makes it possible to reach operational, functional, ergonomic, economic, etc. levels. significant following the positioning defined above.

Au niveau des aspects mécaniques, le montage est d'approche relativement aisée tout en permettant une configuration de fixation rigide pour pouvoir encaisser comme il se doit l'ensemble des chocs et vibrations lors des différents mouvements subis par le système canon comme décrits préalablement.In terms of mechanical aspects, the assembly is relatively easy to approach while allowing a rigid fixing configuration to be able to properly absorb all the shocks and vibrations during the various movements undergone by the barrel system as described previously.

De plus, pour favoriser un tel montage, il est avantageux que la tourelle, et plus particulièrement l'environnement au niveau de l'interface autour du système canon, ne subisse que de légères modifications structurelles. Ces dernières peuvent apparaître essentiellement au niveau de l'épaississement du tube de protection du système canon. C'est pourquoi, le dispositif selon l'invention peut être monté avantageusement sur tous les tubes de protection reliés au fourreau des systèmes canon de moyen et gros calibres.In addition, to promote such an assembly, it is advantageous for the turret, and more particularly the environment at the level of the interface around the gun system, to undergo only slight structural modifications. The latter can appear mainly at the level of the thickening of the protection tube of the gun system. This is why the device according to the invention can be advantageously mounted on all the protection tubes connected to the sheath of medium and large caliber gun systems.

Description de formes d'exécution préférées de l'inventionDescription of preferred embodiments of the invention

Comme le montrent les Figures 1 et 2, l'élément de base de l'invention est le support d'interface 1. As the Figures 1 and 2 , the basic element of the invention is the interface support 1.

D'un point de vue structurel d'abord, il s'agit d'un élément rigide et interchangeable disposé au niveau d'une tourelle 2, montée sur un véhicule blindé quelconque, et plus particulièrement sur le tube de protection 3 relié au fourreau du système canon 4 à la jonction avec le masque 5 de ladite tourelle 2. From a structural point of view first, it is a rigid and interchangeable element arranged at a turret 2, mounted on any armored vehicle, and more particularly on the protection tube 3 connected to the sheath. of the gun system 4 at the junction with the mask 5 of said turret 2.

Ce support d'interface 1 est constitué d'une enveloppe essentiellement semi-circulaire ou semi-cylindrique 6 définie comme étant un support entourant le tube de protection 3 du système canon 4. Cette enveloppe essentiellement semi-circulaire ou semi-cylindrique 6 est surmontée d'une embase 7, au-dessus de laquelle apparaît un plateau 8. This interface support 1 consists of an essentially semi-circular or semi-cylindrical envelope 6 defined as being a support surrounding the protection tube 3 of the gun system 4. This essentially semi-circular or semi-cylindrical envelope 6 is surmounted by a base 7, above which appears a plate 8.

Perpendiculairement au plateau 8 se trouve un support 9 au niveau duquel va venir s'attacher le système de visée 10. Le système de visée 10 vient se fixer à un endroit quelconque dudit support 9, autrement dit la hauteur à laquelle s'attachent les deux dispositifs mentionnés ci-avant n'a aucun impact sur l'aspect structurel du support d'interface 1. Perpendicular to the plate 8 is a support 9 at which will attach the sighting system 10. The sighting system 10 is fixed at any place of said support 9, in other words the height to which the two attach. devices mentioned above has no impact on the structural aspect of the interface support 1.

En ce qui concerne l'ensemble des éléments décrits ci-dessus, à savoir le tube de protection 3, l'enveloppe semi-circulaire ou semi-cylindrique 6, l'embase 7, le plateau 8, le support 9 et le système de visée 10, ceux-ci sont fixés respectivement l'un à l'autre par exemple grâce à un système de vis (ou boulons) selon le montage défini préalablement.With regard to all the elements described above, namely the protection tube 3, the semi-circular or semi-cylindrical casing 6, the base 7, the plate 8, the support 9 and the referred to 10, these are respectively fixed to each other for example by means of a system of screws (or bolts) according to the assembly defined previously.

Les dimensions des différents éléments constitutifs du support d'interface 1 peuvent varier en fonction de la nature du système de visée 10 inséré mais doivent être comprises respectivement dans une certaine gamme définie par des valeurs minimales et maximales pour répondre favorablement aux aspects structurels et fonctionnels du support d'interface 1. Mécaniquement, le mode d'accroche ne doit en aucun cas être modifié suite à une quelconque variation des dimensions dudit support d'interface 1. The dimensions of the various constituent elements of the interface support 1 may vary depending on the nature of the sighting system 10 inserted but must be respectively included in a certain range defined by minimum and maximum values to respond favorably to the structural and functional aspects of the system. interface support 1. Mechanically, the attachment mode must in no case be modified following any variation in the dimensions of said interface support 1.

L'objectif structurel recherché repose sur le fait que l'emplacement dudit support d'interface 1 est caractérisé par une zone rigide adéquate pour un mode de fixation spécifique (voir ci-dessus), zone qui est influencée par l'encombrement défini par les modules environnants (autres systèmes de visée, mitrailleuse coaxiale, etc.).The desired structural objective is based on the fact that the location of said interface support 1 is characterized by a rigid area suitable for a specific method of attachment (see above), an area which is influenced by the size defined by the surrounding modules (other sighting systems, coaxial machine gun, etc.).

D'un point de vue fonctionnel à présent, le support d'interface 1 décrit ci-avant présente la caractéristique d'être inséré à un endroit au niveau duquel les chocs et vibrations ressentis par ledit support d'interface 1 sont d'une intensité moindre par rapport à celle subie dans d'autres environnements de la tourelle 2 ou du système canon 4. From a functional point of view now, the interface support 1 described above has the characteristic of being inserted at a location at which the shocks and vibrations felt by said interface support 1 are of an intensity less than that experienced in other turret 2 or gun system 4 environments.

Le mode de fixation selon la présente invention :

  • est mécaniquement aisé et peu coûteux,
  • n'engendre que de légères modifications structurelles localisées essentiellement au niveau de l'épaississement du tube de protection 3 du système canon 4.
The method of fixing according to the present invention:
  • is mechanically easy and inexpensive,
  • only causes slight structural modifications located mainly at the level of the thickening of the protection tube 3 of the barrel system 4.

Le support d'interface 1 est fixé sur une tourelle montée sur un véhicule blindé quelconque sur laquelle est associé un système canon 4 de différents calibres couvrant la gamme des moyens et gros calibres, autrement dit entre 20 mm et 120 mm.The interface support 1 is fixed on a turret mounted on any armored vehicle on which is associated a gun system 4 of different calibers covering the range of medium and large calibers, in other words between 20 mm and 120 mm.

Cette approche de fixation, confirmée par simulation numérique, est le résultat de plusieurs investigations menées à divers endroits de la tourelle 2 ou du système canon 4. Parmi ceux-ci, on peut mentionner les essais suivants effectués en vue du positionnement du support d'interface 1 :

  • sur le masque 5 avec le support d'interface 1 localisé dans le plan horizontal du système canon 4,
  • sur le système canon 4 lui-même avec le support d'interface 1 placé dans le plan horizontal du système canon 4.
This fixing approach, confirmed by digital simulation, is the result of several investigations carried out at various locations of the turret 2 or of the gun system 4. Among these, we can mention the following tests carried out with a view to the positioning of the support. interface 1:
  • on the mask 5 with the interface support 1 located in the horizontal plane of the gun system 4,
  • on the gun system 4 itself with the interface support 1 placed in the horizontal plane of the gun system 4.

Pour les tests des différents emplacements possibles, on a tenu compte d'un ensemble de mouvements du système canon 4, caractérisés respectivement par un déplacement vertical, horizontal ou les deux simultanément. Les quatre possibilités liées à ces mouvements sont les suivantes :

  • véhicule et tourelle statiques,
  • véhicule à l'arrêt et tourelle en rotation,
  • véhicule en mouvement et tourelle fixe,
  • véhicule et tourelle mobiles.
For the tests of the various possible locations, account was taken of a set of movements of the gun system 4, characterized respectively by a vertical or horizontal displacement or both simultaneously. The four possibilities linked to these movements are as follows:
  • static vehicle and turret,
  • vehicle stationary and rotating turret,
  • moving vehicle and fixed turret,
  • mobile vehicle and turret.

Au final, à hauteur du support d'interface 1 vient s'attacher un système de visée 10 non-spécifique, système de visée 10 considéré comme étant un dispositif principal et/ou secondaire par rapport aux autres systèmes de visée greffés sur la tourelle 2. La spécificité fonctionnelle sera définie in fine par les contraintes contractuelles.In the end, at the height of 1 carrier interface 10 will be attached a non-specific target system, target system 10 considered to be a primary and / or secondary to other graft sighting systems on turret 2 . functional specificity will be determined ultimately by the contractual constraints.
