Description

Le domaine technique de l'invention est celui des systèmes de tir de projectiles et en particulier des caissons (ou pods) lance-missiles montés sur une plateforme, par exemple un véhicule.The technical field of the invention is that of projectile firing systems and in particular missile launchers (or pods) mounted on a platform, for example a vehicle.

Les systèmes de tir de projectiles comportant un caisson contenant au moins un projectile sont bien connus. Ces systèmes sont montés sur une plateforme, telle qu'un véhicule, et ils permettent le pointage et le tir d'un ou de plusieurs projectiles tels que des missiles ou des roquettes.Projectile firing systems comprising a box containing at least one projectile are well known. These systems are mounted on a platform, such as a vehicle, and they allow the aiming and firing of one or more projectiles such as missiles or rockets.

Afin d'empêcher l'entrée de corps étrangers dans le caisson du système de tir, il est classiquement connu d'obturer ce caisson avec une trappe articulée comme on peut le voir dans le brevet FR3026479 .In order to prevent the entry of foreign bodies into the casing of the firing system, it is conventionally known to close this casing with a hinged hatch as can be seen in the patent. FR3026479 .

La trappe est destinée à s'ouvrir par pivotement autour d'un axe de site grâce à un moyen motorisé pour permettre le tir du projectile ou bien le réapprovisionnement du caisson avec un ou plusieurs nouveaux projectiles.The hatch is intended to be opened by pivoting around a site axis by means of a motorized means to allow the firing of the projectile or else the resupply of the box with one or more new projectiles.

Lors des opérations de réapprovisionnement du système de tir, l'ouverture motorisée de la trappe impose de mettre sous tension électrique le système de tir pour pouvoir activer l'ouverture de la trappe.During operations to replenish the firing system, the motorized opening of the hatch requires that the firing system be energized in order to be able to activate the opening of the hatch.

En outre, l'ouverture en site de la trappe n'est pas toujours favorable à l'accessibilité de l'extrémité du caisson, en particulier lorsque celui-ci est situé en superstructure d'un véhicule.In addition, the opening in elevation of the hatch is not always favorable to the accessibility of the end of the box, in particular when the latter is located in the superstructure of a vehicle.

L'invention vise à simplifier les opérations de réapprovisionnement d'un système de tir en n'imposant pas la mise sous tension du système de tir.The invention aims to simplify the operations for restocking a firing system by not requiring that the firing system be powered up.

Ainsi, l'invention porte sur un système de tir de projectile, en particulier un lance missile, comportant un caisson qui est destiné à contenir au moins un projectile et dont une extrémité est obturée par au moins une trappe, trappe qui est articulée par l'un de ses cotés relativement au caisson grâce à une première charnière, système de tir caractérisé en ce que la trappe comporte un ouvrant qui est articulé par rapport à la trappe grâce à une seconde charnière orientée perpendiculairement à la première charnière.Thus, the invention relates to a projectile firing system, in particular a missile launcher, comprising a housing which is intended to contain at least one projectile and one end of which is closed off by at least one hatch, which hatch is articulated by one of its sides relative to the box thanks to a first hinge, firing system characterized in that the hatch comprises an opening which is hinged relative to the hatch thanks to a second hinge oriented perpendicular to the first hinge.

Avantageusement, la première charnière permet un pivotement de la trappe autour d'un axe horizontal.Advantageously, the first hinge allows pivoting of the hatch around a horizontal axis.

Avantageusement, le système de tir comporte un moyen moteur permettant le pivotement de la trappe autour de la première charnière.Advantageously, the firing system comprises motor means allowing the hatch to pivot around the first hinge.

Avantageusement, la trappe comporte un dormant en forme de L sur lequel est articulé l'ouvrant.Advantageously, the hatch comprises an L-shaped frame on which the opening is articulated.

Avantageusement, l'ouvrant comporte un verrou destiné à interdire le pivotement de la seconde charnière.Advantageously, the opening comprises a lock intended to prevent the pivoting of the second hinge.

Avantageusement, l'ouvrant comporte une moyen de maintien en position ouverte destiné à bloquer l'ouvrant à la perpendiculaire d'un plan de la trappe.Advantageously, the opening comprises a means for maintaining in the open position intended to block the opening perpendicular to a plane of the hatch.

L'invention sera mieux comprise à la lecture de la description suivante, description faite en référence aux dessins en annexe, dessins dans lesquels :

  • La figure 1 représente une vue de trois quarts d'un système de tir selon l'invention fixé sur une tourelle de véhicule.
  • La figure 2 représente une vue de détail du système de tir avec une trappe en position fermée et son ouvrant également fermé.
  • La figure 3 représente une vue de détail du système de tir avec une trappe en position ouverte, l'ouvrant solidaire de la trappe étant fermé.
  • La figure 4 représente une vue de détail du système de tir avec une trappe en position fermée et l'ouvrant de la trappe en position ouverte.
The invention will be better understood on reading the following description, description given with reference to the accompanying drawings, drawings in which:
  • The figure 1 shows a three-quarter view of a firing system according to the invention attached to a vehicle turret.
  • The figure 2 shows a detailed view of the firing system with a hatch in closed position and its opening also closed.
  • The figure 3 shows a detail view of the firing system with a hatch in the open position, the opening integral with the hatch being closed.
  • The figure 4 shows a detailed view of the firing system with a hatch in the closed position and the hatch opening in the open position.

Selon la figure 1, une tourelle 200 d'un véhicule 100 est armée d'un système de tir 1 disposé sur l'une des parois 201 latérale et verticale de la tourelle 200. Le système de tir 1 est orientable en site par rapport à la paroi 201 autour d'un axe de site 101 grâce à des moyens de pointage électrique ou hydrauliques (moyens de pointage non représentés).According to figure 1 , a turret 200 of a vehicle 100 is armed with a firing system 1 arranged on one of the lateral and vertical walls 201 of the turret 200. The firing system 1 is orientable in elevation relative to the wall 201 around a site axis 101 by means of electrical or hydraulic pointing means (pointing means not shown).

L'orientation en gisement du système de tir 1 se fait par le pivotement de la tourelle 200 autour d'un axe de gisement 201 et relativement au châssis du véhicule 100.The orientation in bearing of the firing system 1 is effected by the pivoting of the turret 200 about a bearing axis 201 and relative to the chassis of the vehicle 100.

Selon la figure 2, le système de tir 1 comporte un caisson 2 qui selon le mode de réalisation illustré présente un profil carré. Le caisson 2 est destiné à contenir au moins un projectile, ici un missile 8, et il forme ainsi un tube de lancement pour ce missile.According to figure 2 , the firing system 1 comprises a box 2 which according to the illustrated embodiment has a square profile. The box 2 is intended to contain at least one projectile, here a missile 8, and it thus forms a launch tube for this missile.

L'arrière AR du caisson 2 (figure 1) est obturé par une trappe 3 comportant sur son coté supérieur une première charnière 4 dont l'axe est parallèle à l'axe de site 101, donc ici sensiblement horizontal.The rear AR of box 2 ( figure 1 ) is closed off by a hatch 3 comprising on its upper side a first hinge 4 whose axis is parallel to the site axis 101, therefore here substantially horizontal.

La trappe 3 porte un ouvrant 5 qui a ici une forme carrée de dimensions légèrement inférieures à celles de la forme carrée de la trappe 3 et qui est fixé à une partie de la trappe 3 qui forme un dormant 3a et qui est en forme de L.The hatch 3 carries an opening 5 which here has a square shape with dimensions slightly smaller than those of the square shape of the hatch 3 and which is fixed to a part of the hatch 3 which forms a frame 3a and which is L-shaped .

Comme on le voit à la figure 2, le dormant 3a comporte ainsi une barre supérieure horizontale 3a1 portant la première charnière 4 et une barre latérale 3a2 qui est verticale et qui porte une deuxième charnière 9 sur laquelle est fixé l'ouvrant 5.As seen at the figure 2 , the frame 3a thus comprises a horizontal upper bar 3a1 carrying the first hinge 4 and a side bar 3a2 which is vertical and which carries a second hinge 9 on which the leaf 5 is fixed.

L'essentiel de l'obturation du caisson 2 est donc assuré par l'ouvrant 5. Un verrou 6 permet de rendre solidaires l'ouvrant 5 et le dormant 3a, interdisant ainsi l'ouverture par pivotement de l'ouvrant 5 par rapport à la trappe 3. Des moyens d'étanchéité entre le dormant 3a et l'ouvrant 5 seront prévus, par exemple des joints déformables. L'épaisseur de l'ouvrant 5 sera avantageusement la même que celle du dormant 3a.Most of the sealing of the box 2 is therefore provided by the opening 5. A lock 6 makes it possible to make the opening 5 and the frame 3a integral, thus preventing opening. by pivoting of the opening 5 relative to the hatch 3. Sealing means between the frame 3a and the opening 5 will be provided, for example deformable seals. The thickness of the opening 5 will advantageously be the same as that of the frame 3a.

Selon la figure 3, un moyen moteur 7, tel qu'un vérin électrique ou hydraulique, peut être mis en œuvre à condition d'activer les servitudes énergétiques du système de tir 1 (mettre sous tension le système de tir).According to figure 3 , a motor means 7, such as an electric or hydraulic cylinder, can be implemented on condition of activating the energy easements of the firing system 1 (switching on the firing system).

Le vérin 7 permet, lors des phases de fonctionnement du système de tir, l'ouverture en site vers le haut de la trappe 3 par pivotement de celle-ci autour de la première charnière 4.The jack 7 allows, during the operating phases of the firing system, the opening in elevation of the hatch 3 by pivoting the latter around the first hinge 4.

D'autres moyens moteurs classiquement connus de l'Homme du Métier seraient possibles. Par exemple un moteur électrique associé à un train d'engrenage ou bien à des poulies et une courroie ou des pignons et une chaîne pourront être employés en tant que moyen moteur 7 pour ouvrir et fermer la trappe 3.Other motor means conventionally known to those skilled in the art would be possible. For example an electric motor associated with a gear train or else with pulleys and a belt or pinions and a chain could be used as motor means 7 to open and close the hatch 3.

On note que la trappe 3 est suffisamment ouverte de manière à être dégagée de la trajectoire du jet propulsif du missile 8, jet qui est éjecté par la tuyère de ce dernier (jet propulsif non représenté).It is noted that the hatch 3 is sufficiently open so as to be clear of the path of the propellant jet of the missile 8, which jet is ejected by the nozzle of the latter (propellant jet not shown).

En outre, en ouvrant la trappe 3 vers le haut tel que sur le présent mode de réalisation, le caisson 2 pourra être orienté en site sans risque d'interférence avec des éléments du véhicule situés vers le bas, tels que le toit par exemple.In addition, by opening the hatch 3 upwards as in the present embodiment, the box 2 can be oriented in elevation without risk of interference with elements of the vehicle located downwards, such as the roof for example.

Selon la figure 4, la trappe 4 est fermée mais l'ouvrant 5 est ouvert par pivotement autour de la seconde charnière 9, qui est solidaire de la barre latérale 3a2 de la trappe 3 et disposée perpendiculairement à la première charnière 4.According to figure 4 , the hatch 4 is closed but the opening 5 is opened by pivoting around the second hinge 9, which is integral with the side bar 3a2 of the hatch 3 and arranged perpendicular to the first hinge 4.

Le verrou 6 pourra être un verrou à fonctionnement manuel classiquement connu de l'Homme du Métier tel que le verrou décrit dans le brevet IT7921144 par exemple.The lock 6 may be a manually operated lock conventionally known to those skilled in the art such as the lock described in the patent. IT7921144 for example.

Il pourra comporter une fermeture à clé pour bloquer l'accès au contenu du caisson 2. Un moyen de maintien en position ouverte (par exemple un étai mis en place manuellement) pourra être adjoint à l'ouvrant afin de bloquer l'ouvrant dans cette dernière position et empêcher sa fermeture durant le rechargement du tube 2 (moyen de maintien en position non représenté).It may include a key lock to block access to the contents of the box 2. A means of holding in the open position (for example a stay put in place manually) may be added to the opening in order to block the opening in this opening. last position and prevent its closing during reloading of the tube 2 (means for maintaining in position not shown).

On constate donc que l'invention permet un réapprovisionnement du caisson 2 sans devoir procéder à un démarrage des servitudes énergétiques du système de tir 1 et donc sans nécessiter d'actionner un quelconque moyen moteur. Un servant peut simplement ouvrir l'ouvrant et recharger le caisson 2.It can therefore be seen that the invention allows the box 2 to be replenished without having to start the energy easements of the firing system 1 and therefore without requiring the actuation of any motor means. A servant can simply open the door and reload box 2.

L'ouverture de l'ouvrant 5 se faisant autour d'un axe vertical, la manœuvre de cet ouvrant est facilitée par rapport à celle de la trappe elle-même qui, une fois ouverte, forme un obstacle limitant l'accès au caisson.The opening of the leaf 5 being around a vertical axis, the operation of this leaf is facilitated compared to that of the hatch itself which, once open, forms an obstacle limiting access to the box.
