Description

La présente invention concerne un engin sous-marin tel qu'un sous-marin proprement dit.The present invention relates to an underwater vehicle such as a submarine proper.

Les sous-marins de cette nature sont quasiment toujours équipés d'une station hydraulique centralisée, qui produit une énergie utilisable pour différentes applications à bord.Submarines of this nature are almost always equipped with a centralized hydraulic station, which produces usable energy for various applications on board.

En particulier cette énergie hydraulique est extrêmement bien adaptée à la manœuvre des mâts de l'engin comme par exemple la manœuvre asservie d'un périscope, ou autres. Un tel dispositif hydraulique de hissage et d'affalage d'un mât mobile est connu du document EP 1 162 137 A2 . Un dispositif pneumatique est connu à partir du US 2015/0102967 A1 .In particular, this hydraulic energy is extremely well suited to the maneuvering of the masts of the machine such as, for example, the controlled maneuver of a periscope, or the like. Such a hydraulic device for hoisting and lowering a mobile mast is known from the document. EP 1,162,137 A2 . A pneumatic device is known from US 2015/0102967 A1 .

Mais pour différentes raisons et en particulier des raisons de discrétion, d'encombrement, de coût, d'entretien et de volume dans la coque, de telles stations hydrauliques centralisées de génération d'énergie, tendent à disparaître au profit d'autres stations utilisant d'autres énergies, telles que par exemple l'énergie pneumatique ou l'énergie électrique.But for various reasons and in particular reasons of discretion, space, cost, maintenance and volume in the hull, such centralized hydraulic power generation stations, tend to disappear in favor of other stations using other energies, such as for example pneumatic energy or electrical energy.

L'énergie électrique du réseau de bord du sous-marin est parfois employée pour des vérins électriques de manœuvre de ce type de mâts. Cette énergie ne présente pas toujours la disponibilité et la discrétion requise.The electrical energy from the submarine's on-board network is sometimes used for electric jacks for maneuvering this type of mast. This energy does not always have the availability and discretion required.

L'énergie pneumatique, fiable et disponible en quantité à bord, ne facilite pas la réalisation d'un asservissement de position. Elle peut être bruyante pour l'équipage lors de l'utilisation du mât.The pneumatic energy, reliable and available in quantity on board, does not facilitate the achievement of a position control.

Le but de l'invention est donc de résoudre ces problèmes.The object of the invention is therefore to solve these problems.

L'invention sera mieux comprise à la lecture de la description qui va suivre, donnée uniquement à titre d'exemple et faite en se référant au dessin annexé, qui représente un schéma synoptique illustrant la structure et le fonctionnement d'une partie d'un engin sous-marin selon l'invention et comportant des moyens oléopneumatiques de manœuvre d'un mât de celui-ci.The invention will be better understood on reading the description which follows, given solely by way of example and made with reference to the appended drawing, which represents a block diagram illustrating the structure and the operation of part of a underwater vehicle according to the invention and comprising oleopneumatic means for maneuvering a mast thereof.

On a en effet représenté sur cette figure, un schéma synoptique illustrant la structure et le fonctionnement d'une installation d'alimentation en énergie de moyens de manœuvre d'au moins un mât d'un engin sous-marin.This figure shows a block diagram illustrating the structure and operation of an energy supply installation for maneuvering means of at least one mast of an underwater vehicle.

Ces moyens de manœuvre permettent par exemple la manœuvre comme le hissage et l'affalage d'un mât de l'engin tel que par exemple un mât de périscope d'un sous-marin proprement dit.These maneuvering means allow for example maneuvering such as hoisting and lowering a mast of the craft such as for example a periscope mast of a submarine proper.

Ces moyens de manœuvre sont désignés par la référence générale 1 sur cette figure et comportent alors par exemple au moins un vérin de manœuvre dont la tige 1a est fixe et le corps 1b mobile pour le mode de réalisation représenté.These maneuvering means are designated by the general reference 1 in this figure and then comprise for example at least one maneuvering cylinder whose rod 1a is fixed and the body 1b movable for the embodiment shown.

Par ailleurs l'engin sous-marin comporte également un réseau d'air de bord à haute pression, désigné par la référence générale 2 sur cette figure.Furthermore, the underwater vehicle also has a high-pressure on-board air network, designated by the general reference 2 in this figure.

En fait, ce réseau de bord 2, peut par exemple être un réseau de bord à une pression comprise entre 150 et 250 bars en environnement courant.In fact, this on-board network 2, can for example be an on-board network at a pressure of between 150 and 250 bars in a current environment.

En fait, les moyens 1 de manœuvre du mât comprennent des moyens oléopneumatiques désignés par la référence générale 3 sur cette figure, comportant une première partie hydraulique 4, de déplacement du mât, et une seconde partie pneumatique 5, de mise sous pression de la première partie 4, à partir du réseau de bord d'air à haute pression 2 de l'engin sous-marin.In fact, the means 1 for maneuvering the mast include oleopneumatic means designated by the general reference 3 in this figure, comprising a first hydraulic part 4, for moving the mast, and a second part tire 5, for pressurizing the first part 4, from the high-pressure air edge network 2 of the underwater vehicle.

En fait et comme cela est illustré, dans l'engin selon l'invention, il est prévu un séparateur air/hydraulique, désigné par la référence générale 6 sur cette figure, dont la partie air 7 est associée à la seconde partie pneumatique 5 des moyens oléopneumatiques 3 et dont la partie hydraulique est associée à la première partie hydraulique 4 de ces moyens oléopneumatiques 3, comme cela sera décrit plus en détails par la suite.In fact and as illustrated, in the machine according to the invention, an air / hydraulic separator is provided, designated by the general reference 6 in this figure, the air part 7 of which is associated with the second pneumatic part 5 of the oleopneumatic means 3 and whose hydraulic part is associated with the first hydraulic part 4 of these oleopneumatic means 3, as will be described in more detail below.

Comme cela est illustré, la partie air 7 du séparateur air/hydraulique 6, est en effet raccordée à la sortie d'un distributeur par exemple à commande électrique, désigné par la référence générale 8, et comportant au moins une entrée raccordée à des moyens d'alimentation en air sous pression, désignée par la référence générale 9, et une sortie raccordée à des moyens de détente, désignés par la référence générale 10.As illustrated, the air part 7 of the air / hydraulic separator 6 is in fact connected to the outlet of a distributor, for example with electric control, designated by the general reference 8, and comprising at least one inlet connected to means pressurized air supply, designated by the general reference 9, and an outlet connected to expansion means, designated by the general reference 10.

Dans l'exemple de réalisation illustré sur cette figure, les moyens d'alimentation en air sous pression 9 comprennent par exemple des moyens formant détendeur, désignés par la référence générale 11, permettant ainsi de délivrer au reste du circuit, une pression par exemple à 150 bars, à partir d'une pression nominale de 250 bars du réseau d'air de bord à haute pression 2.In the embodiment illustrated in this figure, the means for supplying pressurized air 9 comprise, for example, regulator means, designated by the general reference 11, thus making it possible to deliver to the rest of the circuit, a pressure for example at 150 bars, from a nominal pressure of 250 bars of the high-pressure on-board air network 2.

Les moyens de détente comprennent quant à eux, par exemple au moins une bouteille de détente, désignée par la référence générale 13 sur cette figure, associée à un silencieux de détente de l'air dans le reste de l'engin sous-marin, ce silencieux étant désigné par la référence générale 14.The expansion means comprise, for example, at least one expansion bottle, designated by the general reference 13 in this figure, associated with an air expansion silencer in the rest of the underwater vehicle, this silencer being designated by the general reference 14.

La partie hydraulique 15 du séparateur air/hydraulique 6 comporte une sortie d'alimentation associée à un accumulateur oléopneumatique à haute pression, désigné par la référence générale 16 sur cette figure, et raccordée à travers un distributeur proportionnel 17, à une grande chambre du vérin des moyens de manœuvre 1 du mât de l'engin.The hydraulic part 15 of the air / hydraulic separator 6 comprises a supply outlet associated with a high pressure oleopneumatic accumulator, designated by the general reference 16 in this figure, and connected through a proportional distributor 17, to a large chamber of the jack. maneuvering means 1 of the mast of the machine.

Le distributeur proportionnel 17 comporte également un trajet de retour raccordé à la partie hydraulique 15 du séparateur 6.The proportional distributor 17 also has a return path connected to the hydraulic part 15 of the separator 6.

On notera que les moyens de manœuvre 1 du mât comprennent le vérin, dont la tige est par exemple fixe et que la sortie et le trajet de retour de la partie hydraulique 15 du séparateur 6 sont associés à des clapets d'anti-retour, désignés respectivement par les références 18 et 19.It will be noted that the maneuvering means 1 of the mast include the jack, the rod of which is for example fixed and that the outlet and the return path of the hydraulic part 15 of the separator 6 are associated with non-return valves, designated respectively by the references 18 and 19.

Enfin la petite chambre du vérin des moyens de manœuvre 1, est associée à un accumulateur oléopneumatique de contre-pression, ou de rappel, désigné par la référence générale 20 sur cette figure.Finally, the small chamber of the jack of the maneuvering means 1 is associated with an oleopneumatic accumulator of back pressure, or of return, designated by the general reference 20 in this figure.

Comme cela a été indiqué précédemment, on détourne le principe du vérin oléopneumatique vers le séparateur situé en amont du distributeur proportionnel, fonctionnant au hissage et à l'affalage du mât.As indicated above, the principle of the oleopneumatic cylinder is diverted towards the separator located upstream of the proportional distributor, operating at hoisting and lowering the mast.

Ce séparateur alimente une réserve de fluide hydraulique à haute pression, réalisée par un accumulateur oléopneumatique, permettant de stocker un peu plus d'huile qu'il n'en faut pour effectuer une course complète de déploiement du mât.This separator supplies a high-pressure hydraulic fluid reserve, produced by an oleopneumatic accumulator, allowing to store a little more oil than is necessary to complete a full mast deployment stroke.

Ce séparateur est lui-même alimenté par un réseau d'air comprimé du bord par l'intermédiaire d'un détendeur de pression.This separator is itself supplied by an on-board compressed air network via a pressure reducer.

Enfin, un volume de détente est disposé en aval du distributeur d'air vers la purge dans le bord, de manière à créer une détente rapide dans le séparateur et par voie de conséquence si le distributeur 17 est en position retour, dans la grande chambre du vérin des moyens de manœuvre du mât.Finally, an expansion volume is arranged downstream of the air distributor towards the purge in the edge, so as to create a rapid expansion in the separator and consequently if the distributor 17 is in the return position, in the large chamber of the mast maneuvering means cylinder.

C'est donc ce volume de détente qui permet d'affaler le mât plus vite que les mâts oléopneumatiques ralentis par une phase de détente lente.It is therefore this expansion volume that makes it possible to lower the mast faster than the oleopneumatic masts slowed down by a slow expansion phase.

Le réseau d'air à haute pression de bord garantit, comme cela a été indiqué précédemment, une pression comprise par exemple entre 150 et 250 bars en environnement courant.The on-board high-pressure air network guarantees, as indicated above, a pressure of, for example, between 150 and 250 bars in a current environment.

La pression de détente de 150 bars est retenue à titre d'exemple.The expansion pressure of 150 bars is used as an example.

L'utilisation d'une pression élevée permet de réduire de façon très importante, le volume du vérin et des dispositifs associés c'est-à-dire des accumulateurs, bouteilles d'air, circuits et accessoires.The use of high pressure makes it possible to significantly reduce the volume of the jack and of the associated devices, that is to say accumulators, air bottles, circuits and accessories.

Le réseau d'air de bord, après détente à 150 bars est relié à un distributeur électrique intervenant dans la logique d'asservissement.The on-board air network, after expansion to 150 bars is connected to an electrical distributor involved in the servo logic.

La sortie U de ce distributeur électrique est reliée à la chambre pneumatique du séparateur.The output U of this electrical distributor is connected to the pneumatic chamber of the separator.

On notera à cet égard, qu'un montage du distributeur directement sur le séparateur est également possible.In this regard, it should be noted that mounting the distributor directly on the separator is also possible.

La sortie de retour R du distributeur est reliée à une bouteille de détente, en aval de laquelle se trouvent un diaphragme, et un silencieux libérant lentement l'air détendu dans le reste du bord.The return outlet R of the distributor is connected to an expansion bottle, downstream of which there is a diaphragm, and a silencer slowly releasing the relaxed air in the rest of the edge.

Le séparateur 6 peut être constitué par un accumulateur à piston à haute pression classique, détourné de son usage traditionnel.The separator 6 can be constituted by a conventional high-pressure piston accumulator, diverted from its traditional use.

Ce séparateur dispose de deux sorties hydrauliques dotées de clapets d'anti-retour, respectivement raccordés aux orifices P et R du distributeur hydraulique proportionnel 17.This separator has two hydraulic outlets with non-return valves, respectively connected to ports P and R of the proportional hydraulic distributor 17.

Entre le séparateur et l'orifice P de celui-ci, un accumulateur oléopneumatique à haute pression constitue la réserve d'énergie hydraulique, qui peut être pré-chargée avant de commander le hissage du mât de manière à masquer la lenteur intrinsèque à l'étage pneumatique.Between the separator and the orifice P thereof, a high pressure oleopneumatic accumulator constitutes the reserve of hydraulic energy, which can be preloaded before controlling the hoisting of the mast so as to mask the slowness intrinsic to the pneumatic stage.

Le distributeur proportionnel 17 est utile aussi bien en hissage qu'en affalage, afin de maîtriser à la fois la vitesse et la position du mât dans les deux sens.The proportional distributor 17 is useful both in hoisting and in lowering, in order to control both the speed and the position of the mast in both directions.

La sortie U du distributeur proportionnel est reliée à la grande chambre du vérin de hissage.The output U of the proportional distributor is connected to the large chamber of the lifting cylinder.

La petite chambre du vérin des moyens de manœuvre 1 est reliée à un accumulateur oléopneumatique de rappel ou de contre-pression.The small chamber of the actuating means cylinder 1 is connected to an oleopneumatic accumulator for return or back pressure.

A partir du moment où le mât est placé en mode veille, la pression ou le niveau de l'accumulateur à haute pression est surveillé(e).As soon as the mast is placed in standby mode, the pressure or the level of the high-pressure accumulator is monitored.

Si le mât est plus bas que la position nominale de travail et si la pression à haute pression n'est pas nominale, le distributeur d'air 8 est actionné durant une durée temporisée prédéterminée juste nécessaire au remplissage de l'accumulateur.If the mast is lower than the nominal working position and if the high-pressure pressure is not nominal, the air distributor 8 is actuated for a predetermined time delay just necessary to fill the accumulator.

Il convient de noter que, grâce au détendeur 9, la pression maximale et donc le niveau de remplissage de l'accumulateur 16, ne dépassera jamais un seuil prédéterminé, et ce quelle que soit la durée d'ouverture du distributeur d'air 8 et le niveau initial de l'accumulateur.It should be noted that, thanks to the regulator 9, the maximum pressure and therefore the filling level of the accumulator 16 will never exceed a predetermined threshold, regardless of the duration of the opening of the air distributor 8 and the initial level of the accumulator.

Le distributeur d'air revenant au repos, la chambre pneumatique du séparateur 6 se vide rapidement dans la bouteille de détente puis plus lentement dans le bord.With the air distributor returning to rest, the pneumatic chamber of the separator 6 empties quickly into the expansion bottle and then more slowly into the rim.

Dans cet état, le mât peut être asservi en hissage, grâce à la réserve à haute pression, mais il peut aussi être asservi en affalage, la contre-pression dans la petite chambre repoussant le piston du séparateur.In this state, the mast can be slaved in hoisting, thanks to the high pressure reserve, but it can also be slaved in slump, the back pressure in the small chamber pushing back the piston of the separator.

Si le mât est dans sa position nominale de travail et que la pression P descend sous un seuil déterminé, le distributeur d'air 8 est à nouveau activé pour regonfler l'accumulateur à haute pression.If the mast is in its nominal working position and the pressure P drops below a determined threshold, the air distributor 8 is again activated to re-inflate the high pressure accumulator.

Si le mât reçoit un ordre d'affalage, le distributeur d'air 8 reçoit un ordre de détente quel que soit son état antérieur et l'état de la temporisation de compression.If the mast receives a lowering order, the air distributor 8 receives an expansion order whatever its previous state and the state of the compression time delay.

Le distributeur hydraulique proportionnel reçoit des ordres parallèles mais dissociés de la logique de distribution d'air.The proportional hydraulic distributor receives parallel but separate orders from the air distribution logic.

Ces ordres proviennent par exemple d'un système de management de combat par exemple en fonction de la nécessité opérationnelle de hissage ou d'affalage du mât.These orders come, for example, from a combat management system, for example according to the operational need to hoist or lower the mast.

La loi de commande du distributeur proportionnel est alors une loi classique de maintien de la position et de la vitesse. Le mât fonctionne par exemple en réponse à une consigne de ralliement d'une position, avec écrêtage selon un seuil de vitesse maximale du mât. La vitesse d'écrêtage peut être fixée ou être programmée en fonction de l'écart mesuré entre la position de consigne et la position du mât à un instant donné.The proportional distributor control law is then a classic law for maintaining position and speed. The mast operates for example in response to a rallying instruction for a position, with clipping according to a maximum speed threshold of the mast. The clipping speed can be fixed or programmed according to the difference measured between the set position and the mast position at a given time.

L'usage d'un distributeur proportionnel justifie de s'affranchir de ralentisseurs en fin de course.The use of a proportional distributor justifies eliminating retarders at the end of the race.

On conçoit alors qu'une telle structure présente un certain nombre d'avantages au niveau des conditions de hissage et d'affalage du mât, tout en étant beaucoup plus simple d'utilisation, moins encombrante et plus silencieuse.It is therefore understood that such a structure has a number of advantages in terms of hoisting and lowering the mast, while being much easier to use, less bulky and quieter.

Il va de soi bien entendu que d'autres modes de réalisation encore peuvent être envisagés.It goes without saying of course that still other embodiments can be envisaged.
