Description

BOITIER DESTINE A ETRE DISPOSE SUR UN VEHICULE ET SYSTEME D'ARME COMPRENANT UN TEL BOITIER HOUSING TO BE AVAILABLE ON A VEHICLE AND ARM SYSTEM COMPRISING SUCH A HOUSING
Le domaine technique de 1 ' invention est celui des boîtiers qui sont destinés à être disposés sur un véhicule, et en particulier un véhicule militaire. The technical field of the invention is that of housings that are intended to be arranged on a vehicle, and in particular a military vehicle.
Il est classique de doter un véhicule d'un boîtier, par exemple un coffre à bagages, permettant un emport supplémentaire d'équipements.  It is conventional to provide a vehicle with a housing, for example a luggage compartment, allowing an additional carriage of equipment.
Les véhicules militaires sont fréquemment dotés de tels boîtiers qui permettent de transporter des équipements, des vivres ou des armements.  Military vehicles are frequently equipped with such cases that can carry equipment, food or weapons.
Un boîtier particulier est celui renfermant un système d'arme, par exemple un système de lancement de missiles (ces boîtiers renfermant un canon ou un missile sont souvent dénommés « POD » dans le domaine aéronautique) .  A particular housing is one containing a weapon system, for example a missile launching system (these housings enclosing a gun or a missile are often referred to as "POD" in the aeronautical field).
A titre d'exemple les brevets FR3026479 et FR2394041 décrivent des boîtiers de lancement de missiles déployables.  For example, patents FR3026479 and FR2394041 describe deployable missile launch boxes.
Les boîtiers ont généralement une forme sensiblement parallélépipédique comportant une paroi avant, une paroi arrière, une paroi inférieure, une paroi supérieure et deux parois latérales.  The housings generally have a substantially parallelepipedic shape comprising a front wall, a rear wall, a bottom wall, an upper wall and two side walls.
Généralement les parois avant et arrière comportent au moins un perçage pour permettre la circulation de l'air dans le boîtier dans le but de réduire la température à l'intérieur de celui-ci.  Generally, the front and rear walls have at least one bore to allow air to flow into the housing in order to reduce the temperature inside the housing.
Ce besoin d'aération est particulièrement important lorsque le boîtier renferme un système d'arme, tel qu'un missile. En effet un tel système d'arme comprend des composants électroniques et pyrotechniques qui sont sensibles à la température.  This need for ventilation is particularly important when the housing encloses a weapon system, such as a missile. Indeed, such a weapon system includes electronic and pyrotechnic components that are sensitive to temperature.
Le besoin d'aération de l'intérieur d'un boîtier est aussi présent lorsque le boîtier renferme des composants électroniques ou même des vivres. Lorsque l'aération est assurée par convection naturelle au travers d'ouvertures, il se pose alors le problème d'empêcher la pénétration de particules fines, telles que les grains de sable à l'intérieur du boîtier. On se trouve donc confronté aux besoins contradictoires de faciliter la circulation de l'air tout en interdisant la pénétration de corps étrangers. The need for aeration of the interior of a housing is also present when the housing contains electronic components or even food. When aeration is provided by natural convection through openings, there is the problem of preventing the penetration of fine particles, such as grains of sand inside the housing. We are thus confronted with contradictory needs to facilitate the circulation of air while prohibiting the penetration of foreign bodies.
Les solutions actuelles qui mettent en œuvre des grilles à maille fine ne suffisent malheureusement pas à interdire l'entrée du sable. Par ailleurs ces grilles risquent de se colmater lors du roulage du véhicule ce qui limite les performances de refroidissement de l'intérieur du boîtier.  Current solutions that implement grids fine mesh are unfortunately not enough to prohibit entry of sand. Moreover these grids may clog when running the vehicle which limits the cooling performance of the interior of the housing.
On connaît aussi par le brevet US2014/174283 un conteneur transportant un système lance-missiles. Ce conteneur est un conteneur normalisé 20 pieds de type ISO doté d'une porte d'accès 6, mais il n'est pas décrit ici de moyens d'aération particuliers. On connaît également par la demande de brevet US2009/0073077 un dispositif de mise en place d'une antenne sur une paroi d'un conteneur. L'antenne est fixée sur une paroi interne du conteneur et elle est introduite dans un des orifices de ventilation portés par une paroi du conteneur. Les orifices sont couverts par un boîtier qui forme une cavité interne en regard des orifices de ventilation, cavité ouverte au niveau de sa partie intérieure qui comporte des fentes. Comme précisé plus haut cette fermeture par grille ne suffit pas à interdire l'entrée du sable.  Also known from US2014 / 174283 a container carrying a missile system. This container is a standardized 20 feet ISO type container with an access door 6, but there is no description here of particular aeration means. Also known from US2009 / 0073077 a device for placing an antenna on a wall of a container. The antenna is fixed on an inner wall of the container and is introduced into one of the ventilation holes carried by a wall of the container. The orifices are covered by a housing that forms an internal cavity facing the ventilation holes, cavity open at its inner portion which has slots. As mentioned above this grid closure is not sufficient to prohibit entry of sand.
C'est le but de l'invention que de proposer un boîtier permettant de pallier de tels inconvénients.  It is the object of the invention to provide a housing to overcome such drawbacks.
Le boîtier selon l'invention permet, avec une structure simple, d'assurer le refroidissement interne du boîtier par convection naturelle, tout en interdisant le colmatage des orifices d'aération.  The housing according to the invention allows, with a simple structure, to ensure internal cooling of the housing by natural convection, while preventing clogging of the ventilation openings.
Ainsi l'invention a pour objet un boîtier destiné à être disposé sur un véhicule, en particulier un véhicule militaire, et ayant une forme sensiblement parallélépipédique comportant une paroi avant, une paroi arrière, une paroi inférieure, une paroi supérieure et deux parois latérales, les parois avant et arrière comportant chacune au moins un perçage pour permettre la circulation de l'air à l'intérieur du boîtier, boîtier caractérisé en ce qu'au moins une des parois avant ou arrière porte une plaque qui est disposée à l'extérieur du boîtier et à distance de ladite paroi, le ou les perçages de la paroi considérée étant disposé (s) au voisinage d'un bord supérieur de ladite paroi, le boîtier comportant par ailleurs au moins une première fente permettant le passage de l'air entre la plaque et la paroi considérée, fente qui est localisée au voisinage d'un bord inférieur de ladite paroi, la plaque ayant également au moins une deuxième dimension inférieure à celle de la paroi considérée de telle sorte qu'il y ait au moins une deuxième fente constituée par l'intervalle entre un bord latéral de la plaque et ladite paroi, le boîtier comportant au moins une tôle fermant l'espace entre la plaque et la paroi au niveau d'un bord supérieur et d'au moins un bord latéral de la paroi considérée . Thus, the subject of the invention is a housing intended to be placed on a vehicle, in particular a vehicle. military, and having a substantially parallelepipedal shape having a front wall, a rear wall, a bottom wall, an upper wall and two side walls, the front and rear walls each having at least one hole to allow the circulation of air to the inside the housing, characterized in that at least one of the front or rear walls carries a plate which is arranged outside the housing and at a distance from said wall, the hole or bores of the wall considered being arranged ) in the vicinity of an upper edge of said wall, the housing further comprising at least a first slot allowing the passage of air between the plate and the wall considered, which slot is located in the vicinity of a lower edge of said wall, the plate also having at least a second dimension smaller than that of the wall considered so that there is at least one second slot formed by the gap between a side edge of the plate and said wall, the housing having at least one sheet closing the space between the plate and the wall at an upper edge and at least one side edge of the wall considered.
Selon un mode de réalisation, la ou les premières fentes sont portées par la plaque et aménagées au voisinage d'un bord inférieur de la plaque.  According to one embodiment, the first slot or slots are carried by the plate and arranged in the vicinity of a lower edge of the plate.
Selon un autre mode de réalisation, la plaque pourra avoir au moins une première dimension inférieure à celle de la paroi considérée de telle sorte qu'au moins une première fente soit constituée par l'écart entre un bord inférieur de la plaque et ladite paroi.  According to another embodiment, the plate may have at least a first dimension smaller than that of the wall considered so that at least a first slot is formed by the gap between a lower edge of the plate and said wall.
Avantageusement la tôle pourra être prolongée au moins sur un bord au-delà de la plaque de façon à constituer un déflecteur .  Advantageously, the sheet may be extended at least on one edge beyond the plate so as to constitute a deflector.
D'une façon préférée, la tôle ne s'étendra pas jusqu'au bord inférieur de la paroi . Avantageusement la plaque pourra comporter une entaille coupant un angle inférieur de façon à créer une dissymétrie de la plaque. In a preferred manner, the sheet will not extend to the lower edge of the wall. Advantageously, the plate may comprise a notch intersecting a lower angle so as to create an asymmetry of the plate.
La plaque pourra être une plaque d'acier à blindage.  The plate may be a shielded steel plate.
Selon un mode particulier de réalisation, la paroi inférieure du boîtier pourra porter au moins un trou d'évacuation de l'eau, un panneau étant disposé en dessous de la paroi inférieure et à distance du ou des trous, panneau comportant une partie médiane parallèle à la paroi inférieure et prolongée par deux ailes latérales qui s'éloignent progressivement de la paroi inférieure à partir de la partie médiane .  According to a particular embodiment, the bottom wall of the housing may carry at least one water discharge hole, a panel being disposed below the bottom wall and at a distance from the hole or holes, a panel having a parallel medial portion. at the bottom wall and extended by two lateral wings which progressively move away from the lower wall from the middle part.

En se reportant à la figure la, un véhicule 1 porte au niveau d'un renfoncement 2 un boîtier 3 selon l'invention. Referring to Figure la, a vehicle 1 door at a recess 2 a housing 3 according to the invention.
Le véhicule sera par exemple un véhicule militaire blindé doté d'une tourelle et le renfoncement 2 sera aménagé sur la tourelle. Le boîtier pourra être solidaire de la tourelle et la partie horizontale 2a du renfoncement 2 correspondra dans ce cas tout simplement au châssis du véhicule. Le boîtier 3 sera alors disposé à distance du châssis du véhicule.  The vehicle will be for example an armored military vehicle with a turret and the recess 2 will be built on the turret. The housing may be secured to the turret and the horizontal portion 2a of the recess 2 will simply be in this case simply the chassis of the vehicle. The housing 3 will then be spaced apart from the chassis of the vehicle.
Le boîtier 3 pourra renfermer un système d'arme, tel qu'un lanceur de missile ou de roquettes.  The housing 3 may contain a weapon system, such as a missile launcher or rocket.
Ce système n'est pas représenté en détails. Il comporte une platine portant un lanceur et le boîtier 3 est en particulier orientable en site par pivotement autour d'un axe de pointage 4. Le pointage en gisement est assuré par le pivotement de la tourelle elle-même. Alternativement, le boîtier 3 peut être fixe par rapport à la tourelle. Dans ce cas, c'est le système d'arme disposé dans le boîtier 3 qui va être conçu de façon à pouvoir pivoter autour de l'axe de pointage 4. Cette rotation sera couplée à un moyen permettant d'ouvrir le toit 7 du boîtier 3 pour permettre la sortie du système d'arme, le boîtier 3 restant fixe. This system is not shown in detail. It comprises a plate carrying a launcher and the housing 3 is in particular swivelable by pivoting around a pointing axis 4. The bearing pointing is ensured by the pivoting of the turret itself. Alternatively, the housing 3 can be fixed relative to the turret. In this case, it is the weapon system disposed in the housing 3 which will be designed so as to pivot about the pointing axis 4. This rotation will be coupled to a means for opening the roof 7 of the housing 3 to allow the output of the weapon system, the housing 3 remaining fixed.
Pour permettre le tir, par exemple du missile, une paroi avant 5 du boîtier est montée pivotante par rapport au boîtier. On a représenté par le trait mixte 6 l'axe de pivotement de la paroi avant 5. Alternativement, comme précisé plus haut, lorsque le boîtier 3 est fixe et que c'est le toit 7 du boîtier 3 qui s'ouvre pour permettre la sortie du système d'arme, la paroi avant 5 reste fixe.  To allow shooting, for example missile, a front wall 5 of the housing is pivotally mounted relative to the housing. The swivel axis of the front wall 5 is represented by the mixed line 6. Alternatively, as mentioned above, when the housing 3 is fixed and it is the roof 7 of the housing 3 which opens to allow the output of the weapon system, the front wall 5 remains fixed.
Tous ces éléments structurels ne sont pas l'objet de l'invention et ne sont donc pas décrits en détails. On pourra se reporter au brevet FR3026479 qui décrit un mode de réalisation d'un boîtier lanceur.  All these structural elements are not the subject of the invention and are therefore not described in detail. We can refer to the patent FR3026479 which describes an embodiment of a caster casing.
Le boîtier 3 a une forme sensiblement parallélépipédique et il comporte donc une paroi avant 5, une paroi arrière 10, une paroi inférieure (non visible sur la figure la) , une paroi supérieure 7 et deux parois latérales 8 et 9.  The housing 3 has a substantially parallelepipedal shape and therefore comprises a front wall 5, a rear wall 10, a bottom wall (not visible in Figure la), an upper wall 7 and two side walls 8 and 9.
Les parois avant 5 et arrière 10 comportent chacune au moins un perçage pour permettre la circulation de l'air à l'intérieur du boîtier 3. L'air circule par convection forcée et c'est le déplacement du véhicule qui assure la circulation de l'air qui entre dans le boîtier 3 par la paroi avant 5 et qui en sort par la paroi arrière 10.  The front walls 5 and rear 10 each comprise at least one hole to allow the circulation of air inside the housing 3. The air circulates by forced convection and it is the movement of the vehicle which ensures the circulation of the air that enters the housing 3 through the front wall 5 and exits through the rear wall 10.
La figure lb montre une vue latérale du boîtier 3. On remarque que le boîtier 3 comporte une paroi inférieure 18 qui n'est pas plane mais qui comprend une partie avant 18a et une partie arrière 18b sensiblement parallèles et séparées par un plan de liaison avant 18c. Cette configuration matérialise un caisson arrière 19 qui permet en particulier de loger les moyens de motorisation du déploiement du boîtier 3 renfermant le système d'arme. Un plan incliné arrière 18d relie la partie arrière 18b de la paroi inférieure à la paroi arrière 10. FIG. 1b shows a side view of the housing 3. Note that the housing 3 has a bottom wall 18 which is not flat but which comprises a front part 18a and a rear part 18b substantially parallel and separated by a front connection plane 18c. This configuration materializes a rear box 19 which allows in particular to house the motorization means of the deployment of the housing 3 enclosing the weapon system. A rear inclined plane 18d connects the rear portion 18b of the bottom wall to the rear wall 10.
Les figures 2a et 2b montrent un premier mode de réalisation de la partie avant du boîtier 3.  Figures 2a and 2b show a first embodiment of the front part of the housing 3.
Comme on le voit en particulier sur la figure 2b, la paroi avant 5 porte une plaque 11 qui est disposée à l'extérieur du boîtier 3 et à une distance d de la paroi avant 5.  As seen in particular in Figure 2b, the front wall 5 carries a plate 11 which is disposed outside the housing 3 and at a distance d from the front wall 5.
La plaque 11 est fixée à distance de la paroi avant 5 par l'intermédiaire d' entretoises 12 (ici quatre entretoises cylindriques) . La plaque 11 est vissée sur les entretoises 12 qui sont, elles-mêmes vissées ou soudées à la paroi 5.  The plate 11 is fixed at a distance from the front wall 5 by means of spacers 12 (here four cylindrical spacers). The plate 11 is screwed onto the spacers 12 which are themselves screwed or welded to the wall 5.
On voit sur les figures que la paroi 5 porte des perçages It can be seen in the figures that the wall 5 carries bores
13 qui sont ici constitués par cinq rainures 13 réalisées dans la paroi 5. Ces rainures sont représentées en pointillés sur la figure 2a car elles sont cachées par la plaque 11. 13 which are constituted by five grooves 13 made in the wall 5. These grooves are shown in dashed lines in FIG. 2a because they are hidden by the plate 11.
Les rainures 13 sont disposées au voisinage d'un bord supérieur 5a de la paroi avant 5.  The grooves 13 are arranged in the vicinity of an upper edge 5a of the front wall 5.
Bien entendu, les rainures 13 pourraient être remplacées par un ensemble de perçages cylindriques.  Of course, the grooves 13 could be replaced by a set of cylindrical bores.
Par ailleurs le boîtier 3 comporte une première fente 14 permettant le passage de l'air entre la plaque 11 et la paroi 5.  Furthermore, the housing 3 has a first slot 14 allowing the passage of air between the plate 11 and the wall 5.
Cette première fente 14 est localisée au voisinage d'un bord inférieur 5b de la paroi avant 5.  This first slot 14 is located in the vicinity of a lower edge 5b of the front wall 5.
Comme on le voit à la figure 2a, la plaque 11 a une première dimension Dl qui est inférieure à la dimension correspondante de la paroi avant 5. Ainsi la première fente As seen in Figure 2a, the plate 11 has a first dimension D1 which is smaller than the corresponding dimension of the front wall 5. Thus the first slot
14 est constituée par l'écart entre un bord inférieur lia de la plaque 11 et ladite paroi avant 5. 14 is formed by the gap between a lower edge 11a of the plate 11 and said front wall 5.
Comme on le voit également à la figure 2a, la plaque 11 a une deuxième dimension D2 qui est inférieure à la dimension correspondante de la paroi avant 5. Il y a donc une deuxième fente 15 qui est constituée par l'intervalle entre un bord latéral 11b de la plaque 11 et la paroi avant 5. As can also be seen in FIG. 2a, the plate 11 has a second dimension D2 which is smaller than the dimension corresponding to the front wall 5. There is therefore a second slot 15 which is constituted by the gap between a lateral edge 11b of the plate 11 and the front wall 5.
Le boîtier 3 comporte aussi une tôle 16 qui ferme l'espace 17 entre la plaque 11 et la paroi avant 5 au niveau du bord supérieur 5a de la paroi avant 5.  The housing 3 also comprises a sheet 16 which closes the space 17 between the plate 11 and the front wall 5 at the upper edge 5a of the front wall 5.
Cette tôle 16 s'étend également le long d'un bord latéral 5c de la paroi avant 5 et ferme aussi à ce niveau l'espace 17 séparant la plaque 11 et la paroi 5. Comme on le voit sur la figure 2b, la tôle 16 ne s'étend pas au-delà du bord inférieur lia de la plaque 11.  This sheet 16 also extends along a lateral edge 5c of the front wall 5 and also closes at this level the space 17 separating the plate 11 and the wall 5. As can be seen in FIG. 16 does not extend beyond the lower edge 11a of the plate 11.
Ainsi, la tôle 16 ne s'étend pas jusqu'au bord inférieur 5b de la paroi 5. Il en résulte une fente latérale 20. La tôle 16 est prolongée au moins sur un de ses bords, au-delà de la plaque 5, de façon à constituer un déflecteur 16a.  Thus, the sheet 16 does not extend to the lower edge 5b of the wall 5. This results in a lateral slot 20. The sheet 16 is extended at least on one of its edges, beyond the plate 5, so as to constitute a deflector 16a.
La tôle 16 couvre ainsi deux côtés de la plaque 11, et elle couvre aussi, dans l'exemple dessiné, le coin coupé lie séparant les bords 11c et lld de la plaque 11.  The sheet 16 thus covers two sides of the plate 11, and it also covers, in the drawn example, the cut wedge lie separating the edges 11c and 11d of the plate 11.
Le fonctionnement de cet assemblage est le suivant.  The operation of this assembly is as follows.
Lors du roulage du véhicule, l'air s'introduit par la première fente 14 entre la plaque 11 et la paroi avant 5. La tôle 16 empêche l'évacuation de l'air qui est obligé de s'écouler vers les rainures 13 portées par la paroi avant 5. L'air s'introduit dans le boîtier 3 par ces rainures 13. Le sable qui serait conduit vers la paroi avant 5 avec le flux d'air est gêné dans sa progression par sa propre masse. Il ne peut pénétrer par les rainures 13. Le sable tombe par gravité et s'évacue au travers de la fente 20.  During the running of the vehicle, the air is introduced through the first slot 14 between the plate 11 and the front wall 5. The plate 16 prevents the evacuation of the air which is forced to flow towards the grooves 13 carried by the front wall 5. The air is introduced into the housing 3 by these grooves 13. The sand that would be led to the front wall 5 with the air flow is hindered in its progression by its own mass. It can not penetrate through the grooves 13. The sand falls by gravity and is evacuated through the slot 20.
Le surplus de l'air s'évacue par la deuxième fente 15 qui permet également en partie l'évacuation du sable vers l'extérieur et empêche l'engorgement de l'espace 17.  The excess air is evacuated by the second slot 15 which also partly allows the evacuation of the sand to the outside and prevents clogging of the space 17.
Le profil du déflecteur 16 assure une protection latérale de la plaque 11 et canalise le flux d'air incident. La paroi arrière du boîtier 3 pourrait être équipée d'un montage de plaque 11 analogue. Il n'est pas nécessaire de décrire une telle configuration, les figures décrites et associées à une paroi avant peuvent être transposées pour une paroi arrière. Ce montage n'est cependant pas indispensable, le mouvement d'aération s 'effectuant de façon privilégiée de l'avant vers l'arrière du boîtier 3. The profile of the deflector 16 provides lateral protection of the plate 11 and channels the incident air flow. The rear wall of the housing 3 could be equipped with a similar plate mounting 11. It is not necessary to describe such a configuration, the figures described and associated with a front wall can be transposed for a rear wall. This assembly is however not essential, the ventilation movement is carried out in a preferred manner from the front to the rear of the housing 3.
La plaque 11 doit par contre être impérativement installée au niveau de la paroi qui se situe vers l'avant dans le sens de progression normal du véhicule.  However, the plate 11 must be installed at the level of the wall which is located forwardly in the direction of normal progression of the vehicle.
Par ailleurs la plaque 11 sera avantageusement réalisée en acier à blindage. Elle contribuera alors à la protection du boîtier 3 contre les tirs d'armes automatiques. La paroi avant 5 pourra être réalisée en un alliage léger, par exemple d'aluminium.  In addition, the plate 11 will advantageously be made of shielded steel. It will then contribute to the protection of the housing 3 against automatic firearms. The front wall 5 may be made of a light alloy, for example aluminum.
Les figures 3a et 3b montrent un second mode de réalisation de l'invention.  Figures 3a and 3b show a second embodiment of the invention.
Ce mode ne diffère du précédent que par les dimensions de la plaque 11 et par la forme de la première fente 14.  This mode differs from the previous one only in the dimensions of the plate 11 and in the shape of the first slot 14.
Dans ce mode de réalisation la première fente 14 est une simple lumière parallèle au bord inférieur lia de la plaque et qui est percée directement dans la plaque 11. Cette plaque 11 a une longueur Dl qui est donc sensiblement égale à la dimension correspondante de la paroi avant 5.  In this embodiment the first slot 14 is a simple light parallel to the lower edge 11a of the plate and which is pierced directly into the plate 11. This plate 11 has a length D1 which is therefore substantially equal to the corresponding dimension of the wall before 5.
La plaque 11 a ici, comme dans le mode précédent, une deuxième dimension D2 qui est inférieure à la dimension correspondante de la paroi avant 5. Il y a donc toujours une deuxième fente 15 qui est constituée par l'intervalle entre un bord latéral 11b de la plaque et la paroi avant 5.  The plate 11 has here, as in the previous mode, a second dimension D2 which is smaller than the corresponding dimension of the front wall 5. There is therefore always a second slot 15 which is constituted by the gap between a lateral edge 11b of the plate and the front wall 5.
Cette deuxième fente pourrait être omise mais il est nécessaire que l'espace séparant le boîtier 3 de la paroi 2a du renfoncement 2 soit suffisant pour permettre l'évacuation latérale de l'air en excès et du sable. Ce mode de réalisation permet d'augmenter la surface de couverture de la paroi avant 5 par la plaque 11, donc la protection du boîtier contre les tirs. This second slot could be omitted but it is necessary that the space between the housing 3 of the wall 2a of the recess 2 is sufficient to allow lateral evacuation of excess air and sand. This embodiment makes it possible to increase the coverage area of the front wall 5 by the plate 11, thus protecting the housing against firing.
La figure 4 montre un troisième mode de réalisation de l'invention, mode qui ne diffère du premier mode de réalisation que par la présence sur la plaque 11 d'une entaille triangulaire 21 qui est aménagée au niveau d'un angle inférieur et qui coupe cet angle inférieur.  FIG. 4 shows a third embodiment of the invention, which mode differs from the first embodiment only in the presence on the plate 11 of a triangular notch 21 which is arranged at a lower angle and which cuts this lower angle.
L'entaille 21 est ici plus particulièrement positionnée au niveau de l'angle inférieur gauche, situé à l'opposé de la fente 20.  The notch 21 is here more particularly positioned at the lower left angle, located opposite the slot 20.
Cette entaille 21 permet de créer une dissymétrie dans l'écoulement de l'air à l'intérieur de l'espace 17 séparant la plaque 11 et la paroi 5. Il résulte de cette dissymétrie un écoulement tourbillonnaire de l'air dans l'espace 17 ce qui favorise l'évacuation des grains de sable. L'entaille 21 pourrait être réalisée sous la forme d'un arrondi assurant la dissymétrie de la partie inférieure de la plaque 11. La figure 4 peut être associée à la figure 2b, la vue en coupe étant identique pour ces deux modes de réalisation.  This cut 21 makes it possible to create an asymmetry in the flow of air inside the space 17 between the plate 11 and the wall 5. This asymmetry results in a swirling flow of air into space. 17 which favors the evacuation of grains of sand. The notch 21 could be made in the form of a rounding ensuring the dissymmetry of the lower part of the plate 11. Figure 4 can be associated with Figure 2b, the sectional view being identical for these two embodiments.
La figure 5 montre, de façon agrandie et en coupe partielle, la partie inférieure du caisson 19 qui est visible à la figure lb . On voit que la paroi inférieure 18b porte des trous 22 permettant l'évacuation de l'eau hors du caisson 19.  Figure 5 shows, in an enlarged manner and in partial section, the lower part of the box 19 which is visible in Figure lb. It can be seen that the bottom wall 18b carries holes 22 enabling the water to be discharged out of the box 19.
Un panneau 23 est disposé en dessous de la paroi inférieure 18b et à distance des trous 22. Ce panneau 23 comporte une partie médiane 23a qui est parallèle à la paroi inférieure 18b et qui est prolongée par deux ailes latérales 23b et 23c qui s'éloignent progressivement de la paroi inférieure 18b à partir de la partie médiane 23a.  A panel 23 is disposed below the bottom wall 18b and away from the holes 22. This panel 23 has a middle part 23a which is parallel to the bottom wall 18b and which is extended by two side wings 23b and 23c which are moving away. progressively from the lower wall 18b from the middle portion 23a.
Le panneau 23 se fixe à la paroi inférieure 18b par des entretoises 24. Ce profil progressif en amont et en aval des trous 22 crée, lors du roulage du véhicule, un effet Venturi qui permet de faciliter l'éjection des quelques grains de sable qui, en dépit de la plaque d'entrée 11, ou pendant une phase de tir (réelle ou simulée) , auraient malgré tout réussi à pénétrer dans le boîtier 3. The panel 23 is fixed to the lower wall 18b by spacers 24. This progressive profile upstream and downstream of the holes 22 creates, during the rolling of the vehicle, a Venturi effect that facilitates the ejection of some grains of sand that, despite the input plate 11, or during a shooting phase (real or simulated), would still managed to penetrate the housing 3.
Par ailleurs les trous 22 permettent, à l'arrêt du véhicule, d'améliorer le refroidissement de l'intérieur du boîtier 3 par un effet de convection naturelle, l'air frais entre alors dans le boîtier 3 par les trous 22 et en ressort au niveau des perçages des parois avant 5 et arrière 10.  Moreover, the holes 22 make it possible, when the vehicle is stopped, to improve the cooling of the interior of the case 3 by a natural convection effect, the fresh air then enters the case 3 through the holes 22 and comes out of it. at the holes of the front walls 5 and rear 10.
Les ailes latérales 23b et 23c du panneau 23 sont ici des portions de plaque planes formant un angle constant avec la paroi inférieure 18b. Les ailes pourraient être réalisées également sous la forme de portions de plaque courbes.  The side wings 23b and 23c of the panel 23 are here planar plate portions forming a constant angle with the bottom wall 18b. The wings could be made also in the form of curved plate portions.
L'effet venturi en dessous du caisson 19 peut être obtenu de façon différente.  The venturi effect below the box 19 can be obtained differently.
La figure 6 montre ainsi, d'une façon analogue à la figure lb, une vue latérale du boîtier 3. La paroi inférieure 18 du boîtier 3 est positionnée à proximité du plan 2a du renfoncement 2. La partie arrière 18b de la paroi inférieure 18, qui forme également le fond du caisson 19, est délimitée par le plan de liaison avant 18c et par le plan incliné arrière 18d qui ont des inclinaisons sensiblement symétriques par rapport à un plan vertical.  FIG. 6 thus shows, in a manner similar to FIG. 1b, a side view of the housing 3. The bottom wall 18 of the housing 3 is positioned near the plane 2a of the recess 2. The rear portion 18b of the bottom wall 18 , which also forms the bottom of the box 19, is delimited by the connecting plane before 18c and by the rear inclined plane 18d which have inclinations substantially symmetrical with respect to a vertical plane.
Lors de l'avance du véhicule, l'air est canalisé entre le plan 2a du renfoncement 2 et les plans inclinés 18c et 18d. Le profil convergent puis divergent de la section de passage de l'air, en amont et en aval des trous 22, crée, lors du roulage du véhicule, l'effet Venturi recherché. On facilite ainsi l'éjection des grains de sable.  During the advance of the vehicle, the air is channeled between the plane 2a of the recess 2 and the inclined planes 18c and 18d. The profile converges and then diverge from the air passage section, upstream and downstream of the holes 22, creates, during the rolling of the vehicle, the desired Venturi effect. This facilitates the ejection of the grains of sand.
Une telle disposition est possible lorsque le boîtier 3 se trouve à proximité du plan 2a du renfoncement 2.  Such an arrangement is possible when the housing 3 is close to the plane 2a of the recess 2.
La figure 7 montre un autre mode de réalisation dans lequel le boîtier 3 est à une distance relativement importante du plan 2a du renfoncement 2. Un panneau 23 est disposé en dessous de la paroi inférieure 18b et à distance des trous 22. Le panneau 23 se fixe à la paroi inférieure 18b par des entretoises 24. FIG. 7 shows another embodiment in which the housing 3 is at a relatively large distance from the plane 2a of the recess 2. A panel 23 is disposed below the bottom wall 18b and at a distance 22. The panel 23 is fixed to the bottom wall 18b by spacers 24.
Contrairement à celui décrit en référence à la figure 5, le panneau 23 est ici plan et parallèle à la paroi inférieure 18b. Le panneau est plus long que la paroi inférieure 18b. Il coopère avec les plans inclinés 18c et 18d qui prolongent en amont et en aval la paroi inférieure 18b de façon à former une section de passage de l'air qui a un profil convergent en amont des trous 22, puis divergent en aval des trous 22. Là encore on crée, lors du roulage du véhicule, l'effet Venturi recherché, ce qui permet de faciliter l'éjection des grains de sable.  Unlike that described with reference to Figure 5, the panel 23 is here planar and parallel to the bottom wall 18b. The panel is longer than the bottom wall 18b. It cooperates with the inclined planes 18c and 18d which extend upstream and downstream of the bottom wall 18b so as to form an air passage section which has a convergent profile upstream of the holes 22, and then diverge downstream of the holes 22 Once again, during the running of the vehicle, the desired Venturi effect is created, which facilitates the ejection of the grains of sand.
