Description

L'invention concerne le chargement, c'est-à-dire le remplissage en explosif fondu, de munitions relativement longues. L'invention s'adapte à la fois au procédé de chargement par gravité, et au procédé de chargement par dépression appelé également chargement sous vide.The invention relates to the loading, that is to say the filling with molten explosive, of relatively long munitions. The invention adapts both to the gravity loading process, and to the vacuum loading process also called vacuum loading.

De manière générale, l'explosif fondu est préparé dans des cuves de coulée, équipées de vannes de fond de cuve. Les munitions sont placées verticalement sous les cuves, et le chargement s'effectue par coulée, par gravité ou sous vide. Des cuves basculantes de transfert de l'explosif fondu, entre la cuve de coulée et la munition, peuvent être employées pour charger des grosses bombes, mines et grenades "air-sous-marines", charges militaires de missile ...In general, the molten explosive is prepared in pouring tanks, equipped with bottom tank valves. The ammunition is placed vertically under the tanks, and the loading is carried out by casting, by gravity or under vacuum. Tilting tanks for transferring the molten explosive, between the casting tank and the ammunition, can be used to load large bombs, mines and grenades "air-submarines", military missile charges ...

Lorsque la hauteur de la munition est trop importante pour que celle-ci soit placée, soit sous la cuve de coulée, soit à côté de la cuve basculante, le chargement par coulée par gravité de l'explosif fondu exige des aménagements.When the height of the ammunition is too large for it to be placed either under the pouring tank or next to the tilting tank, loading by gravity casting of the molten explosive requires adjustments.

Une première solution consiste à placer la munition dans une fosse aménagée sous la cuve principale, ou à côté de celle-ci. La réalisation de ce genre de fosse est toujours délicate dans une installation existante, et pose en outre, des problèmes de sécurité, d'entretien, tels que la pollution et l'évacuation des eaux de lavage et de manutention de la munition.A first solution consists in placing the ammunition in a pit arranged under the main tank, or next to it. The realization of this kind of pit is always delicate in an existing installation, and poses moreover, problems of safety, maintenance, such as the pollution and the evacuation of water of washing and handling of the ammunition.

Une autre solution consiste à réhausser ladite cuve en fonction de la hauteur de la munition. Cette opération est très onéreuse et n'est pas toujours possible dans les installations existant déjà.Another solution consists in raising said tank as a function of the height of the munition. This operation is very expensive and is not always possible in existing installations.

Une troisième solution consiste à utiliser une cuve à hauteur ajustable par un dispositif hydraulique de levage. Cette solution limite la capacité des cuves.A third solution consists in using a tank with height adjustable by a hydraulic lifting device. This solution limits the capacity of the tanks.

Une dernière solution consiste à utiliser une pompe pour assurer la circulation de l'explosif fondu entre la cuve et la munition. Cette solution permet le chargement de la munition indépendamment de la hauteur de celle-ci, mais suscite cependant des risques lors de l'opération de chargement et lors des opérations d'entretien, tel que le nettoyage après l'opération de chargement.A last solution consists in using a pump to ensure the circulation of the molten explosive between the tank and the ammunition. This solution allows the ammunition to be loaded regardless of the height thereof, but nevertheless gives rise to risks during the loading operation and during maintenance operations, such as cleaning after the loading operation.

Le but de l'invention est de remédier à cet inconvénient en créant un système de chargement de munitions en explosif fondu utilisant notamment une canalisation souple destinée à remplir lesdites munitions, notamment par siphonnage.The object of the invention is to remedy this drawback by creating a system for loading ammunition with molten explosive, in particular using a flexible pipe intended to fill said ammunition, in particular by siphoning.

L'objet de l'invention est un système de chargement de munitions en explosif fondu, comportant au moins une cuve dans laquelle se trouve l'explosif fondu et possédant au moins un orifice de sortie de l'explosif situé en bas de ladite cuve. Le système se caractérise en ce qu'il comprend une canalisation souple fixée de manière étanche audit orifice par une première extrémité et dont la structure est à double paroi pour permettre la circulation d'un fluide caloporteur pour amener l'explosif fondu dans une munition à charger en le maintenant à une température déterminée .The object of the invention is a system for loading ammunition with molten explosive, comprising at least one tank in which the molten explosive is located and having at least one outlet for the explosive located at the bottom of said tank. The system is characterized in that it comprises a flexible pipe fixed in leaktight manner to said orifice by a first end and the structure of which is double walled to allow the circulation of a heat transfer fluid to bring the molten explosive into a munition to charge by keeping it at a certain temperature.

L'invention et ses caractéristiques seront mieux comprises à la lecture de la description suivante, illustrée des figures représentant respectivement :

  • - Fig.1, un schéma du système selon l'invention ;
  • - Figs.2a et 2b, des vues en coupe transversale de deux réalisations possibles de la canalisation utilisée dans le système selon l'invention ;
  • - Fig.3, l'utilisation du système selon l'invention pour réaliser un chargement de munitions dit "en nougat".
The invention and its characteristics will be better understood on reading the following description, illustrated by the figures representing respectively:
  • - Fig.1, a diagram of the system according to the invention;
  • - Figs.2a and 2b, cross-sectional views of two possible embodiments of the pipe used in the system according to the invention;
  • - Fig.3, the use of the system according to the invention to achieve a load of ammunition called "nougat".

L'installation représentée sur la figure 1 est munie de moyens de mise en dépression 4, c'est donc cette réalisation qui sera d'abord décrite. Il est toutefois à remarquer que le système fonctionne sans ces moyens de mise en dépression, c'est-à-dire par gravité.The installation shown in FIG. 1 is provided with means for placing under vacuum 4, it is therefore this embodiment which will be described first. It should however be noted that the system operates without these means of depressurization, that is to say by gravity.

Il est représenté une cuve principale 1 dans laquelle on prépare l'explosif. Cette cuve peut être aussi une capacité auxiliaire, qui serait l'intermédiaire entre une cuve principale et les munitions. Dans le fond de la cuve est prévu un orifice 7 par lequel doit passer l'explosif fondu. Sur cet orifice 7 est fixée, par une première extrémité 8, une canalisation souple 5 dont la deuxième extrémité 9 est insérée dans une munition 3. Des moyens de contrôle de l'alimentation en explosif 2 ont été représentés à la première extrémité 8 de la canalisation 5. Ils sont constitués d'organes techniques de fond de cuve, par exemple des vannes. Ces organes peuvent être également prévus sur la canalisation 5 ou à sa deuxième extrémité 9.A main tank 1 is shown in which the explosive is prepared. This tank can also be an auxiliary capacity, which would be the intermediary between a main tank and the ammunition. In the bottom of the tank is provided an orifice 7 through which the molten explosive must pass. On this orifice 7 is fixed, by a first end 8, a flexible pipe 5 whose second end 9 is inserted in a munition 3. Means for controlling the supply of explosive 2 have been shown at the first end 8 of the pipe 5. They are made up of technical tank bottom organs, for example valves. These members can also be provided on the pipe 5 or at its second end 9.

La munition 3 est représentée avec une longueur relativement importante, disposée verticalement sur le sol, de manière à ce que l'on puisse constater, que sa hauteur H est supérieur à l'espace restant libre en dessous de la cuve et au-dessus du sol. Pour alimenter cette munition, la canalisation souple décrit un S et forme un siphon, l'explosif fondu se comportant comme un liquide, et tombe dans la munition.Ammunition 3 is shown with a relatively large length, arranged vertically on the ground, so that it can be seen that its height H is greater than the space remaining free below the tank and above the ground. To supply this munition, the flexible pipe describes an S and forms a siphon, the molten explosive behaving like a liquid, and falls into the munition.

Les moyens de mise en dépression 4 sont constitués principalement d'un couvercle 10 à travers lequel passe la deuxième extrémité 9 de la canalisation souple, et un tube 11 traversant également le couvercle 10, mettant ainsi en communication l'intérieur de la munition 3 avec une pompe à faire le vide 12 par l'intermédiaire d'un vase d'expansion 12 permettant de piéger l'explosif fondu..The vacuuming means 4 consist mainly of a cover 10 through which the second end 9 of the flexible pipe passes, and a tube 11 also passing through the cover 10, thus putting the interior of the munition 3 into communication with a vacuum pump 12 by means of an expansion tank 12 making it possible to trap the molten explosive.

Dans le cas du chargement par dépression, les phases sont les suivantes :
- préparation de l'explosif dans la cuve 1 ;
- mise en dépression de l'intérieur de la munition 3 ;
- ouverture de la canalisation souple 5 par les moyens de contrôle de l'alimentation en explosif, et conjointement remplissage de la munition.In the case of vacuum loading, the phases are as follows:
- preparation of the explosive in tank 1;
- depression of the interior of the munition 3;
- Opening of the flexible pipe 5 by the means for controlling the supply of explosive, and jointly filling the munition.

Ce procédé de chargement, équipé du système de chargement selon la présente invention, ne nécessite pas de modifications importantes dans les installations existantes. On constate qu'aucune énergie mécanique engendrée extérieurement n'est apportée à l'explosif fondu. Ce dernier est transféré de la cuve à la munition par siphonnage. La surface de l'explosif fondu n'est nulle part en contact avec l'atmosphère à partir de la cuve de fusion, par conséquent, le procédé convient bien au chargement sous dépression assurant le débullage.This loading process, equipped with the loading system according to the present invention, does not require significant modifications in existing installations. It can be seen that no mechanical energy generated externally is brought to the molten explosive. The latter is transferred from the tank to the ammunition by siphoning. Nowhere is the surface of the molten explosive in contact with the atmosphere from the melting tank, the process is therefore suitable for loading under vacuum ensuring debubbling.

La figure 2a nous montre, par une coupe transversale, la structure de la canalisation souple, selon un premier mode de réalisation. La canalisation a une structure à double paroi. Elle comprend principalement une armature externe 20, une armature interne 21, placée à l'intérieur de l'armature externe, ces deux armatures étant positionnées l'une par rapport à l'autre par un manchon alvéolaire 22 entouré de m'armature externe et englobant l'armature interne. Ce manchon alvéolaire définit par sa structure tubulaire à double paroi une cavité centrale de circulation 24 de l'explosif fondu.Figure 2a shows us, in a cross section, the structure of the flexible pipe, according to a first embodiment. The pipeline has a double wall structure. It mainly comprises an external frame 20, an internal frame 21, placed inside the external frame, these two frames being positioned relative to each other by a cellular sleeve 22 surrounded by the external frame and encompassing the internal frame. This alveolar sleeve defines by its tubular double-wall structure a central cavity for circulation 24 of the molten explosive.

L'armature externe peut être réalisée par une bande de toile ou une gaine de fibre ou de tissu, analogue à celle utilisée pour la fabrication des pneus. La fonction de l'armature externe 20 est en outre de contenir la pression du liquide caloporteur. La fonction de l'armature interne 21 est de résister aux pressions de circulation du fluide caloporteur.The external reinforcement can be produced by a strip of canvas or a sheath of fiber or fabric, similar to that used for the manufacture of tires. The function of the external frame 20 is also to contain the pressure of the heat transfer liquid. The function of the internal frame 21 is to resist the pressures of circulation of the heat transfer fluid.

Des membranes 25, droites ou en hélice, maintiennent l'armature externe 20 par rapport à l'armature interne 21 et définissent selon leur nombre, une ou plusieurs alvéoles de circulation 23 du fluide caloporteur. Ces membranes peuvent être donc droites ou en hélice, la circulation du fluide caloporteur se fera respectivement droite ou en hélice autour de l'armature interne 21, et autour de la cavité centrale 24.Membranes 25, straight or helical, hold the external reinforcement 20 relative to the internal reinforcement 21 and define, according to their number, one or more circulation cells 23 for the heat transfer fluid. These membranes can therefore be straight or helical, the circulation of the heat transfer fluid will be straight or helical respectively around the internal reinforcement 21, and around the central cavity 24.

Les armatures interne et externe 20 et 21 sont des gaines flexibles ou souples, mais en un matériau relativement rigide, tel que l'acier. Elles peuvent avoir, soit une structure en ressort, soit une structure en anneaux. La libération du liquide peut ainsi se faire à un endroit constamment variable dans l'espace. Le manchon alvéolaire 22 est réalisé à l'aide d'un élastomère avec un très bon état de surface interne, de façon à ce que la paroi interne de la cavité centrale 24 ait un état de surface permettant une parfaite propreté lorsque la canalisation souple est vidée. D'autres caoutchoucs synthétiques ou des silicones vulcanisés à chaud peuvent être employés. Pour répartir le liquide caloporteur de manière uniforme autour de l'axe de la cavité centrale, la membrane 25 est de préférence réalisée en hélice..The internal and external reinforcements 20 and 21 are flexible or flexible sheaths, but made of a relatively rigid material, such as steel. They can have either a spring structure or a ring structure. The release of the liquid can thus take place at a constantly variable location in space. The alveolar sleeve 22 is produced using an elastomer with a very good internal surface state, so that the internal wall of the central cavity 24 has a surface state allowing perfect cleanliness when the flexible pipe is emptied. Other synthetic rubbers or hot vulcanized silicones can be used. To distribute the heat transfer liquid uniformly around the axis of the central cavity, the membrane 25 is preferably made in a helix.

Le fluide caloporteur peut être de l'eau surchauffée, de l'huile chaude, de la vapeur, mais en aucun cas le moyen de chauffage ne doit être réalisé par des résistances électriques, dont la précision thermique ne permet pas de respecter les normes de sécurité imposées pour ce type d'installation.The heat transfer fluid can be superheated water, hot oil, steam, but in no case the heating means must be carried out by electric resistances, whose thermal precision does not allow to respect the standards of security imposed for this type of installation.

La canalisation souple peut être prévue en plusieurs parties, dont une ou plusieurs peuvent être rigides, et une ou plusieurs peuvent être souples.The flexible pipe may be provided in several parts, one or more of which may be rigid, and one or more of which may be flexible.

La figure 3 illustre le procédé de chargement dit "en nougat", appliqué au système de chargement selon l'invention. Ce type de chargement "en nougat" est caractérisé par la présence de morceaux solides d'explosifs repérés 40, dans l'explosif liquide.Figure 3 illustrates the loading process called "nougat", applied to the loading system according to the invention. This type of "nougat" charge is characterized by the presence of solid pieces of explosives marked 40, in the liquid explosive.

Le processus habituel de chargement "en nougat" est le suivant :
- introduction à l'intérieur de la munition d'une couche d'explosif fondu ;
- introduction d'une quantité de morceaux d'explosif de manière à combler la quantité de liquide introduit au préalable.The usual "nougat" loading process is as follows:
- introduction into the interior of the munition of a layer of molten explosive;
- introduction of a quantity of pieces of explosive so as to fill the quantity of liquid introduced beforehand.

Ces deux opérations sont réitérées jusqu'à remplissage complet de la munition. Il va sans dire que ce processus comporte beaucoup d'opérations, beaucoup de manutentions et demande donc beaucoup de temps.These two operations are repeated until the ammunition is completely filled. It goes without saying that this process involves a lot of operations, a lot of handling and therefore requires a lot of time.

Selon l'invention on introduit à l'intérieur de la munition tous les morceaux solides d'explosifs. On fixe à travers un bouchon étanche une seringue 41 qui, une fois le bouchon mis en place sur la munition, atteint le fond de celle-ci. Par l'intermédiaire du bouchon étanche, et à l'aide d'un dispositif de mise en dépression 12, on fait le vide à l'intérieur de la munition. Enfin, on introduit l'explosif liquide, au moyen de la seringue 41, raccordée à la canalisation 5, la seringue étant remontée au fur et à mesure du remplissage de l'intérieur de la munition, grâce au fait que la canalisation est souple. On comprend que cette opération de remplissage de l'explosif liquide, à l'aide d'une seringue n'est possible que si l'élément qui alimente la seringue est mobile, ce qui n'est pas le cas dans les dispositifs existant déjà.According to the invention, all the solid pieces of explosives are introduced inside the munition. A syringe 41 is fixed through a sealed stopper which, once the stopper is in place on the munition, reaches the bottom of the latter. By means of the tight plug, and using a vacuum device 12, a vacuum is created inside the munition. Finally, the liquid explosive is introduced, by means of the syringe 41, connected to the pipe 5, the syringe being raised as the interior of the ammunition is filled, thanks to the fact that the pipe is flexible. It is understood that this operation of filling the liquid explosive, using a syringe, is only possible if the element which supplies the syringe is mobile, which is not the case in the devices already existing. .

De plus, ce processus comporte beaucoup moins d'opérations que celui selon l'art antérieur, et respecte toutes les normes de sécurité exigées pour de telles opérations.In addition, this process involves far fewer operations than that according to the prior art, and meets all the safety standards required for such operations.

Bien qu'étant conçu pour des munitions relativement longues, le système de chargement selon l'invention s'applique à des munitions de plus courtes dimensions.Although designed for relatively long ammunition, the loading system according to the invention applies to ammunition of shorter dimensions.
