Description

Le domaine technique de l'invention est celui des déflecteurs de souffle pour véhicule militaire et des véhicules militaires équipés de tels déflecteurs.The technical field of the invention is that of blast deflectors for military vehicles and military vehicles equipped with such deflectors.

Les véhicules militaires comportent souvent des équipements en superstructure qui sont vulnérables au souffle engendré par le tir d'un canon embarqué dont la bouche est située au voisinage de ces équipements.Military vehicles often include equipment on the superstructure which is vulnerable to the blast generated by the firing of an on-board cannon, the muzzle of which is located in the vicinity of this equipment.

Il est connu pour remédier à ce problème de vulnérabilité de démonter les dits équipements lors de périodes de tir prolongées avec l'arme puis de les remonter lors des opérations de mouvement.To remedy this problem of vulnerability, it is known to disassemble said equipment during prolonged periods of firing with the weapon and then to reassemble it during movement operations.

On connaît également par le brevet US6302010 un bouclier destiné à être fixé sur le toit d'un véhicule et comportant trois panneaux articulés. Un panneau central est articulé sur le toit du véhicule et deux panneaux latéraux sont articulés sur le panneau central. Ce bouclier est destiné à protéger un trou d'homme et non un équipement en superstructure. Les panneaux latéraux doivent être manipulés par un opérateur et la mise en place d'un tel bouclier reste délicate et nécessite la présence d'un opérateur pour positionner les panneaux latéraux.It is also known from the patent US6302010 a shield intended to be fixed to the roof of a vehicle and comprising three hinged panels. A central panel is hinged on the roof of the vehicle and two side panels are hinged on the central panel. This shield is intended to protect a manhole and not a superstructure equipment. The side panels must be handled by an operator and the installation of such a shield remains delicate and requires the presence of an operator to position the side panels.

L'invention se propose de résoudre ce problème de vulnérabilité en proposant un déflecteur de souffle qui protège l'équipement lors de l'utilisation de l'arme et qui peut être mis en place facilement pour assurer la protection de l'équipement.The invention proposes to solve this problem of vulnerability by proposing a blast deflector which protects the equipment during the use of the weapon and which can be put in place easily to ensure the protection of the equipment.

Avantageusement, l'invention ne grève pas le volume d'évolution de l'équipement en dehors des phases d'utilisation du canon, ni ne s'oppose de manière significative à l'avancement du véhicule lors des phases de mouvement. Tout aussi avantageusement, l'invention n'impacte pas le fonctionnement de l'équipement protégé.Advantageously, the invention does not affect the volume of evolution of the equipment outside the phases of use of the gun, nor does it significantly oppose the advancement of the vehicle during the phases of movement. Equally advantageously, the invention does not impact the operation of the protected equipment.

Ainsi l'invention porte sur un déflecteur de souffle pour véhicule militaire comportant un panneau central contigu à deux panneaux latéraux disposés de part et d'autre du panneau central, déflecteur caractérisé en ce que les panneaux peuvent être inclinés entre une position relevée apte à dévier le souffle et une position basse où les panneaux sont sensiblement horizontaux, le panneau central étant articulé par rapport au véhicule au moyen d'une articulation située sur un bord inférieur du panneau central, chaque panneau latéral étant articulé par rapport à un bord latéral du panneau central au moyen d'une charnière, un actionneur reliant le panneau central au véhicule et commandant ainsi le mouvement d'abaissement ou de relevage de ce panneau central, chaque panneau latéral comportant une tringle de guidage sur laquelle un palier lisse est apte à glisser et pivoter, chaque palier étant relié à l'actionneur par une bielle qui permet ainsi, lorsque le panneau central s'abaisse, d'abaisser par entrainement les panneaux latéraux tout en les écartant du panneau central afin de placer tous les panneaux dans un même plan sensiblement horizontal une fois abaissés et inversement permet de relever tous les panneaux simultanément en leur donnant une disposition angulaire relativement les uns aux autres pour former une coque protectrice contre le souffle.Thus the invention relates to a blast deflector for a military vehicle comprising a central panel contiguous to two side panels arranged on either side of the central panel, a deflector characterized in that the panels can be inclined between a raised position capable of deflecting the blast and a low position where the panels are substantially horizontal, the central panel being hinged relative to the vehicle by means of a hinge located on a lower edge of the central panel, each side panel being hinged relative to a side edge of the panel central by means of a hinge, an actuator connecting the central panel to the vehicle and thus controlling the movement of lowering or raising of this central panel, each side panel comprising a guide rod on which a sliding bearing is able to slide and pivot, each bearing being connected to the actuator by a connecting rod which thus allows, when the central panel is lowered, to lower er by driving the side panels while moving them away from the central panel in order to place all the panels in the same substantially horizontal plane once lowered and vice versa allows all the panels to be raised simultaneously by giving them an angular arrangement relative to each other to form a protective shell against the blast.

Avantageusement, le panneau central est articulé par rapport à une partie basse fixe comportant trois facettes contigües ayant une disposition angulaire relative les unes aux autres identique à celle des panneaux en position relevée pour former une coque protectrice contre le souffle.Advantageously, the central panel is articulated relative to a fixed lower part comprising three contiguous facets having an angular arrangement relative to each other identical to that of the panels in the raised position to form a protective shell against the blast.

Avantageusement, l'actionneur est un vérin hydraulique.Advantageously, the actuator is a hydraulic cylinder.

Avantageusement, chaque panneau comporte au moins une jambe de force comportant une forme emboîtable destinée à correspondre avec une forme complémentaire correspondante située sur le véhicule ou la partie basse afin de transmettre les efforts du souffle reçus par les panneaux.Advantageously, each panel comprises at least one strut comprising a nestable shape intended to correspond with a corresponding complementary shape located on the vehicle or the lower part in order to transmit the forces of the blast received by the panels.

L'invention porte également sur un véhicule militaire comportant un canon d'artillerie comportant un déflecteur selon des caractéristiques citées précédemment, déflecteur destiné à protéger un élément de superstructure du véhicule situé au voisinage de la bouche du canon de façon telle que, lorsque l'artillerie est abaissée, les panneaux sont mis en position basse au-dessus de la bouche du canon, et que, lorsque le canon est pointé, la coque protectrice dévie le souffle dirigé vers l'élément de superstructure.The invention also relates to a military vehicle comprising an artillery gun comprising a deflector according to the characteristics cited above, the deflector intended to protect a superstructure element of the vehicle located in the vicinity of the muzzle of the gun such that, when the artillery is lowered, the panels are put in a low position above the muzzle, and that, when the cannon is pointed, the protective shell deflects the blast directed at the superstructure element.

Avantageusement, l'élément de superstructure comporte une arme de protection rapprochée.Advantageously, the superstructure element comprises a close protection weapon.

L'invention sera mieux comprise à la lecture de la description suivante, description faite en regard des dessins annexés, dessins dans lesquels :

  • La figure 1 représente une vue de trois quarts d'un véhicule selon l'invention.
  • La figure 2 représente une vue de l'invention en position relevée.
  • La figure 3 représente une vue arrière de l'invention en position intermédiaire.
  • La figure 4 représente une vue de l'invention en position abaissée.
  • La figure 5 représente une vue latérale de l'invention en position abaissée.
The invention will be better understood on reading the following description, description given with reference to the appended drawings, drawings in which:
  • The figure 1 shows a three-quarter view of a vehicle according to the invention.
  • The figure 2 shows a view of the invention in a raised position.
  • The figure 3 shows a rear view of the invention in an intermediate position.
  • The figure 4 shows a view of the invention in the lowered position.
  • The figure 5 shows a side view of the invention in the lowered position.

Selon la figure 1, un véhicule militaire 100 comporte un canon 101 d'artillerie pointé et prêt au tir. Le véhicule 100 comporte également un équipement 102 en superstructure. Cet équipement 102 comporte ici une arme téléopérée 102 pour assurer la protection rapprochée du véhicule 100. Cet équipement 102 se situe dans la trajectoire de l'onde de bouche 103 du canon consécutive au tir. Cette onde de bouche 103 est formée par les gaz propulsifs qui sortent du frein de bouche 17 à la suite du projectile. Le souffle 103 est susceptible de détériorer l'équipement 102 par la brutale surpression. Un déflecteur 1 est ici en position relevé et protège l'équipement 102 contre le souffle 103 émis par l'artillerie lors du tir par déviation du souffle sur la surface extérieur de panneaux 2 et 3 que comporte le déflecteur 1.According to figure 1 , a military vehicle 100 has an artillery gun 101 pointed and ready to fire. The vehicle 100 also includes equipment 102 in the superstructure. This equipment 102 here comprises a remotely operated weapon 102 to ensure close protection of the vehicle 100. This equipment 102 is located in the trajectory of the muzzle wave 103 of the gun following the firing. This muzzle wave 103 is formed by the propellant gases which exit the muzzle brake 17 following the projectile. The blast 103 is liable to damage the equipment 102 by the sudden overpressure. A deflector 1 is here in the raised position and protects the equipment 102 against the blast 103 emitted by the artillery during firing by deflecting the blast on the outer surface of panels 2 and 3 that the deflector 1 comprises.

Selon la figure 2, le déflecteur 1 comporte un panneau central 2 contigu à deux panneaux latéraux 3 disposés de part et d'autre du panneau central, panneaux latéraux également visibles à la figure 1. Le déflecteur 1 est dans une position relevée apte à dévier le souffle par la forme de coque enveloppant partiellement l'équipement 102 à protéger.According to figure 2 , the deflector 1 comprises a central panel 2 contiguous to two side panels 3 arranged on either side of the central panel, side panels also visible at the figure 1 . The deflector 1 is in a raised position capable of deflecting the blast through the form of a shell partially enveloping the equipment 102 to be protected.

Selon un mode de réalisation préféré, visible aux figures 1 à 5, le panneau central 2 est articulé par rapport à une partie basse 9 comportant trois facettes 9a, 9b, 9c contigües ayant une disposition angulaire relative entre facettes 9a 9b, 9c qui est identique à la disposition angulaire des panneaux 2 et 3 en position relevée, de manière à contribuer à former une partie basse de la coque protectrice contre le souffle. Cette partie basse 9 permet de rehausser le déflecteur 1 et comporte des jambes de forces 11 (figure 3) aptes à reprendre les efforts transmis par les panneaux 2 et 3 en position relevée. La reprise des efforts entre les panneaux 2 et 3 et les jambes de force 11 se fait au moyen de formes emboîtables 14 disposées aux extrémités supérieures des jambes de force 11 et destinées à correspondre avec des formes complémentaires 13 solidaires des panneaux 2 et 3.According to a preferred embodiment, visible to the figures 1 to 5 , the central panel 2 is articulated relative to a lower part 9 comprising three contiguous facets 9a, 9b, 9c having a relative angular arrangement between facets 9a 9b, 9c which is identical to the angular arrangement of the panels 2 and 3 in the raised position, so as to contribute to forming a lower part of the protective shell against the blast. This lower part 9 makes it possible to raise the deflector 1 and comprises struts 11 ( figure 3 ) able to take up the forces transmitted by the panels 2 and 3 in the raised position. The resumption of the forces between the panels 2 and 3 and the struts 11 is done by means of interlocking forms 14 arranged at the upper ends struts 11 and intended to correspond with complementary shapes 13 integral with the panels 2 and 3.

Comme visible à la figure 3, le panneau central 2 est articulé par rapport à la partie basse 9 au moyen d'une articulation 4 située sur un bord inférieur du panneau central 2. Chaque panneau latéral 3 est articulé par rapport à un bord latéral du panneau central 2 au moyen d'au moins une charnière 5. Un actionneur 6, en l'espèce un vérin hydraulique ou électrique relie le panneau central 2 à la partie basse 9 et commande ainsi le mouvement d'abaissement ou de relevage du déflecteur 1.As visible at the figure 3 , the central panel 2 is hinged relative to the lower part 9 by means of a hinge 4 located on a lower edge of the central panel 2. Each side panel 3 is hinged relative to a side edge of the central panel 2 by means of 'at least one hinge 5. An actuator 6, in this case a hydraulic or electric cylinder connects the central panel 2 to the lower part 9 and thus controls the movement of lowering or raising of the deflector 1.

Chaque panneau latéral 3 comporte une tringle de guidage 7 disposé de manière oblique par rapport à la direction de sortie de tige du vérin 6, tringle 7 sur laquelle un palier lisse 8 est apte à glisser et pivoter. Chaque palier 8 est relié au vérin 6 par une bielle 12 qui est montée pivotante par rapport au vérin 6 au niveau d'articulations 15 parallèles à la tige du vérin 6.Each side panel 3 comprises a guide rod 7 disposed obliquely with respect to the direction of exit of the rod from the cylinder 6, rod 7 on which a plain bearing 8 is able to slide and pivot. Each bearing 8 is connected to the jack 6 by a connecting rod 12 which is mounted to pivot relative to the jack 6 at the level of joints 15 parallel to the rod of the jack 6.

Ainsi, lorsque le panneau central 2 s'abaisse, il abaisse par entrainement les panneaux latéraux 3 tout en les écartant de lui.Thus, when the central panel 2 is lowered, it lowers by driving the side panels 3 while moving them away from it.

En position abaissée, le panneau 2 se trouve placé vers l'arrière du véhicule dans un plan P sensiblement horizontal et visible aux figures 4 et 5 et les panneaux latéraux 3 sont disposés de part et d'autre du panneau central et sensiblement dans le même plan horizontal P.In the lowered position, the panel 2 is placed towards the rear of the vehicle in a substantially horizontal plane P and visible to figures 4 and 5 and the side panels 3 are arranged on either side of the central panel and substantially in the same horizontal plane P.

Inversement, pour quitter la position abaissée de la figure 4, la rentrée de la tige du vérin 6 permet de relever simultanément tous les panneaux 2 et 3 en faisant glisser les paliers 8 le long des tringles 7 donnant ainsi une disposition angulaire relative entre les panneaux 2 et 3 propre à reformer une coque protectrice contre le souffle une fois les panneaux revenus en position relevée.Conversely, to leave the lowered position of the figure 4 , the retraction of the rod of the jack 6 makes it possible to simultaneously raise all the panels 2 and 3 by sliding the bearings 8 along the rods 7 thus giving a relative angular arrangement between the panels 2 and 3 suitable for reforming a protective shell against the blows once the panels return to the raised position.

Selon la figure 5, l'abaissement des panneaux 2 et 3 permet de donner la possibilité à l'équipement 102 d'avoir un plein débattement en gisement sur 360 degrés et de lui permettre un certain débattement en site négatif.According to figure 5 , the lowering of the panels 2 and 3 makes it possible to give the equipment 102 the possibility of having a full displacement in bearing over 360 degrees and to allow it a certain deflection in negative elevation.

Par ailleurs, la mise en position abaissée des panneaux 2 et 3 limite la prise au vent du déflecteur 1, réduisant ainsi les efforts à l'avancement du véhicule lors des phases de transport.Moreover, the placing of the panels 2 and 3 in the lowered position limits the wind resistance of the deflector 1, thus reducing the forces to advance the vehicle during the transport phases.

De plus le fait d'abaisser le déflecteur 1 sur une partie basse 9 ayant une certaine hauteur permet aux panneaux 2 et 3 de se positionner au-dessus de la bouche du canon 100 lorsque ce dernier est abaissé voisinage de la cabine 16 du véhicule, par exemple durant les phases de transport.In addition, the fact of lowering the deflector 1 on a lower part 9 having a certain height allows the panels 2 and 3 to be positioned above the muzzle of the barrel 100 when the latter is lowered in the vicinity of the cabin 16 of the vehicle, for example during the transport phases.

S'il n'est pas nécessaire d'abaisser ainsi le canon au voisinage de la cabine 16 du véhicule, la partie basse 9 n'est pas indispensable et le déflecteur 1 pourra être directement solidarisé avec la cabine du véhicule.If it is not necessary to lower the barrel in this way in the vicinity of the cabin 16 of the vehicle, the lower part 9 is not essential and the deflector 1 can be directly secured to the cabin of the vehicle.
