Description

La présente invention concerne un mât périscopique. L'invention vise en particulier un mât périscopique pour sous-marin. On connaît déjà, notamment par le document EP-57649 des mâts périscopiques optroniques qui sont télescopiques.The present invention relates to a periscopic mast. The invention relates in particular to a periscopic mast for a submarine. Already known, in particular from document EP-57649, optronic periscopic masts which are telescopic.

Les mâts périscopiques à optiques directes connus comprennent quant à eux généralement un tube optique disposé à l'intérieur d'un cylindre qui est monté à coulissement par rapport à la coque du sous-marin et qui, lorsqu'il n'est pas utilisé, pénètre profondément à l'intérieur de la coque du sous-marin. Le hissage d'un mât périscopique du type précité nécessite au moins deux vérins.Known periscopic masts with direct optics generally comprise an optical tube placed inside a cylinder which is slidably mounted relative to the hull of the submarine and which, when not in use, goes deep inside the hull of the submarine. Hoisting a periscope mast of the above type requires at least two jacks.

De tels mâts périscopiques optiques sont encombrants, favorisent l'instabilité du véhicule porteur, augmentent le maître couple de l'abri de navigation par la présence des paliers de guidage ce qui accroît la résistance à l'avancement et réduit la discrétion acoustique, et nécessitent aussi des circuits hydrauliques de commande des vérins relativement complexes.Such optical periscopic masts are bulky, promote the instability of the carrier vehicle, increase the master torque of the navigation shelter by the presence of the guide bearings which increases the resistance to travel and reduces acoustic discretion, and require also hydraulic circuits for controlling relatively complex cylinders.

Un but de l'invention est de proposer un mât périscopique à voies optiques, notamment pour sous-marin, qui permette de remédier aux inconvénients des dispositifs connus grâce en particulier à une conception télescopique.An object of the invention is to propose a periscopic mast with optical channels, in particular for submarines, which makes it possible to remedy the drawbacks of known devices thanks in particular to a telescopic design.

Ainsi, le mât périscopique pour véhicule sous-marin conforme à l'invention est de type optique et comprend au moins un tube optique mobile en translation autour d'un tube optique fixe solidaire de la coque dudit sous-marin, ledit tube optique mobile étant porté par un carénage profilé monté à coulissement par rapport à la coque, les tubes fixe et mobile étant coaxiaux et étant munis de moyens optiques permettant le cheminement des faisceaux optiques issus de la partie supérieure du tube mobile jusqu'à un poste d'observation dans le prolongement du tube fixe.Thus, the periscope mast for an underwater vehicle according to the invention is of the optical type and comprises at least one optical tube movable in translation around a fixed optical tube secured to the hull of said submarine, said mobile optical tube being carried by a streamlined fairing mounted to slide relative to the hull, the fixed and mobile tubes being coaxial and being provided with optical means allowing the routing of the optical beams coming from the upper part of the mobile tube to an observation post in the extension of the fixed tube.

La structure télescopique à deux tubes coaxiaux du mât conforme à l'invention permet d'en réduire très sensiblement l'encombrement lorsqu'il est en position rétractée à l'intérieur de la coque. En outre, un seul vérin suffit à hisser le tube mobile en position d'utilisation ce qui simplifie considérablement les circuits de commande de hissage du mât.The telescopic structure with two coaxial tubes of the mast according to the invention makes it possible to reduce very much substantially the size when it is in the retracted position inside the shell. In addition, a single cylinder is sufficient to hoist the movable tube into the position of use, which considerably simplifies the control circuits for hoisting the mast.

A la Figure 1, on a représenté un mât périscopique selon l'invention, de type optique, destiné à équiper par exemple un sous-marin (non représenté).In Figure 1, there is shown a periscopic mast according to the invention, of optical type, intended to equip for example a submarine (not shown).

Ce mât 1 comprend esentiellement un premier tube optique 3 mobile en translation autour d'un second tube optique fixe 2 qui est rendu solidaire de la coque 4 du sous-marin par tout moyen approprié, connu en lui-même et non spécifique à l'invention.This mast 1 essentially comprises a first optical tube 3 movable in translation around a second fixed optical tube 2 which is made integral with the hull 4 of the submarine by any suitable means, known in itself and not specific to the invention.

Le tube mobile 3 qui est coaxial au tube fixe 2 et de diamètre légèrement supérieur à celui-ci de manière à coulisser autour de lui, est porte par un carénage profilé en goutte d'eau 5 monté à coulissement dans un évidement 6 de la coque 4.The movable tube 3 which is coaxial with the fixed tube 2 and of diameter slightly greater than the latter so as to slide around it, is carried by a streamlined streamlined fairing 5 mounted to slide in a recess 6 of the shell 4.

En position hissée du mât 1 qui est la position représentée à la Figure 1, le carénage 5 fait saillie par rapport à la coque 4 d'environ une demi-fois la hauteur de ce carénage 5, cette hauteur étant par ailleurs sensiblement égale à la hauteur du tube fixe 2. En position hissée du mât 1, l'extrémité supérieure du tube fixe 2 s'étend dans le tube mobile 3.In the hoisted position of the mast 1 which is the position shown in FIG. 1, the fairing 5 protrudes relative to the hull 4 by about half the time of the height of this fairing 5, this height being moreover substantially equal to the height of the fixed tube 2. In the hoisted position of the mast 1, the upper end of the fixed tube 2 extends in the movable tube 3.

Le coulissement du carénage 5 et par conséquent le hissage du tube mobile 3, est commandé par un vérin hydraulique 7, à simple ou double effet à huile, disposé latéralement par rapport aux tubes fixe 2 et mobile 3.The sliding of the fairing 5 and consequently the hoisting of the movable tube 3 is controlled by a hydraulic cylinder 7, with single or double oil effect, arranged laterally with respect to the fixed 2 and movable 3 tubes.

Dans l'exemple représenté à la Figure 1, le corps 8 du vérin 7 est rendu solidaire de la coque 4 tandis que que sa tige 9 est fixée, par son extrémité supérieure, à la paroi du tube mobile 3. L'alimentation en huile du vérin 7 se fait par une canalisation 10 qui traverse la coque 4 à l'extrémité inférieure du corps 8 du vérin 7. Le vidage de la chambre supérieure 7a du vérin 7 se fait par une canalisation distincte 11 qui chemine à l'intérieur de l'évidement 6 de la coque 4. Bien entendu, ce retour en huile depuis la chambre supérieure 7a peut être incorporé au vérin 7 lui-même. On voit également, à la Figure 1, que le corps 8 du vérin 7 s'étend à l'intérieur de l'évidement 6 et partiellement à l'intérieur du carénage 5 lorsque celui-ci est en position hissée. En position hissée du carénage 5, la tige 9 du vérin 7 s'étend complètement à l'intérieur du carénage 5.In the example shown in Figure 1, the body 8 of the cylinder 7 is made integral with the shell 4 while its rod 9 is fixed, by its upper end, to the wall of the movable tube 3. The oil supply of the jack 7 is done by a pipe 10 which passes through the shell 4 at the lower end of the body 8 of the jack 7. The emptying of the upper chamber 7a of the jack 7 is done by a separate pipe 11 which runs inside the recess 6 of the shell 4. Of course, this return of oil from the upper chamber 7a can be incorporated into the jack 7 itself. It can also be seen in FIG. 1 that the body 8 of the jack 7 extends inside the recess 6 and partially inside the fairing 5 when the latter is in the hoisted position. In the hoisted position of the fairing 5, the rod 9 of the jack 7 extends completely inside the fairing 5.

Selon une variante de réalisation non représentée, le corps 8 du vérin 7 pourrait être directement lié au carénage 5 tandis que sa tige 9 serait alors rendue solidaire de la coque 4, les alimentations hydrauliques s'effectuant alors par des alésages pratiqués dans la tige 9 elle-même.According to a variant embodiment not shown, the body 8 of the jack 7 could be directly linked to the fairing 5 while its rod 9 would then be made integral with the shell 4, the hydraulic supplies then being effected by bores made in the rod 9 herself.

Les moyens de guidage en translation du carénage profilé 5 (non représentés) sont directement incorporés à la structure de l'abri de navigation ou coque 4 du sous-marin, ces moyens de guidage étant par exemple des dispositifs du type à glissières et patins, lesdites glissières pouvant être portées par le carénage 5 ou par la structure de l'abri de navigation 4.The means for translational guiding of the profiled fairing 5 (not shown) are directly incorporated into the structure of the navigation shelter or hull 4 of the submarine, these guiding means being for example devices of the type with runners and runners, said slides being able to be carried by the fairing 5 or by the structure of the navigation shelter 4.

L'extrémité supérieure du tube mobile 3 porte une tête optique 12, coaxiale à ce tube mobile 3, dont la structure interne, orientable en gisement grâce à des moyens électromécaniques non représentés mais connus en eux-même porte des prismes de pointage en élévation (non représentés) des différentes voies du mât 1. La tête optique 12 qui est obturée, de manière étanche, à son extrémité inférieure par un dispositif optique 13 formant hublot, est prolongée par une coiffe externe 14 coaxiale aux tubes fixe 2 et mobile 3. Dans l'exemple représenté à la Figure 1, cette coiffe 14 est montée à rotation autour de l'axe X-X′ des tubes fixe 2 et mobile 3 tandis que des moyens d'étanchéité et d'entraînement en rotation 15 sont prévus à la base de la coiffe 14 et à la périphérie de celle-ci pour, en particulier, réaliser une étanchéité à l'eau entre la coiffe 14 et la tête optique 12 en regard du plan de joint entre la coiffe 14 et le carénage 5. La coiffe externe 14 porte des hublots (non représentés) de passage des faisceaux optiques des différentes voies optiques du mât 1.The upper end of the movable tube 3 carries a optical head 12, coaxial with this movable tube 3, the internal structure of which can be oriented in bearing by means of electromechanical means not shown but known in themselves carries pointing prisms in elevation (not shown) of the different tracks of the mast 1. The optical head 12 which is sealingly closed at its lower end by an optical device 13 forming a window, is extended by an external cap 14 coaxial with the fixed 2 and mobile tubes 3. In the example shown in FIG. 1, this cover 14 is mounted for rotation about the axis XX ′ of the fixed 2 and mobile 3 tubes while sealing and rotation drive means 15 are provided at the base of the cover 14 and at the periphery of that -This, in particular, to achieve a water-tightness between the cap 14 and the optical head 12 opposite the joint plane between the cap 14 and the fairing 5. The outer cap 14 carries portholes (not shown s) passage of the optical beams of the different optical paths of the mast 1.

Dans l'exemple représenté à la Figure 1, la tête optique 12 est mobile en rotation indépendamment du la coiffe 14.In the example shown in FIG. 1, the optical head 12 is movable in rotation independently of the cap 14.

Les moyens d'entraînement en rotation et d'étanchéité 15, du type joint électrique tournant, ne sont pas spéficiques à l'invention et sont connus en eux-mêmes.The rotation drive and sealing means 15, of the rotating electrical joint type, are not specific to the invention and are known in themselves.

Selon une caractéristique avantageuse de l'invention, le mât 1 comprend des moyens électroniques d'asservissement (non représentés), disposés dans un compartiment 16 localisé de préférence à la partie supérieure du carénage 5 et reliés d'une part à des moyens d'alimentation extérieurs (non représentés) par l'intermédiaire d'un premier câble de connexion 17, d'une boîte de raccordement 18, et d'un second câble de connexion 19, et d'autre part à la coiffe 14 par l'intermédiaire d'un câble de connexion 20, lesdits moyens d'asservissement, connus en eux-mêmes et non spécifiques à l'invention, étant conçus pour "recopier" la position de la structure interne de la tête optique 12 et aligner les hublots de la coiffe 14 avec les axes optiques des voies du mât 1. On réalise ainsi un mât 1 équipé d'une coiffe 14 dite "suiveuse".According to an advantageous characteristic of the invention, the mast 1 comprises electronic control means (not shown), arranged in a compartment 16 preferably located at the top of the fairing 5 and connected on the one hand to means of external power supply (not shown) via a first connection cable 17, a connection box 18, and a second connection cable 19, and on the other hand to the cover 14 via a connection cable 20, said control means, known in themselves and not specific to the invention, being designed to "copy" the position of the internal structure of the optical head 12 and align the portholes of the cap 14 with the optical axes of the tracks of the mast 1. This produces a mast 1 equipped with a cap 14 called "follower" .

Le tube fixe 2 comprend à chaque extrémité un dispositif optique 21 formant hublot qui permet le cheminement vers le poste d'observation 22 du mât 1 situé sous ce mât 1, des faisceaux optiques issus de la coiffe 14 et qui assurent en outre une fonction d'étanchéité et de sécurité en cas de défaillance des autres moyens d'étanchéité du mât 1.The fixed tube 2 comprises at each end an optical device 21 forming a porthole which allows the path to the observation post 22 of the mast 1 located under this mast 1, of the optical beams coming from the cap 14 and which also provide a function of sealing and safety in the event of failure of the other sealing means of the mast 1.

L'extrémité inférieure du tube fixe 2 est prolongée par un tube 23 coaxial au tube fixe 2, qui s'étend à l'intérieur de l'abri de navigation du sous-marin et qui contient un miroir 24 permettant le renvoi vers le poste d'observation 22 des faisceaux optiques issus de la coiffe 14. Le poste d'observation 22 regroupe par ailleurs l'ensemble des moyens de commande du mât 1. Il est également possible de centraliser sur un bandeau porté par l'observateur 25 l'ensemble des informations stratégiques nécessaires à la conduite du bâtiment tels qu'en particulier la profondeur d'immersion, le cap, l'azimut du but, l'alerte radar, la vitesse, l'heure, etc...The lower end of the fixed tube 2 is extended by a tube 23 coaxial with the fixed tube 2, which extends inside the navigation shelter of the submarine and which contains a mirror 24 allowing the return to the station observation 22 of the optical beams coming from the cap 14. The observation station 22 also groups together all of the control means of the mast 1. It is also possible to centralize on a strip worn by the observer 25 l all the strategic information necessary for the control of the vessel such as in particular the depth of immersion, the course, the azimuth of the goal, the radar alert, the speed, the time, etc.

L'extrémité du tube 23 adjacente à l'extrémité inférieure du tube fixe 2 est également obturée de manière étanche par un dispositif optique formant hublot 23a.The end of the tube 23 adjacent to the lower end of the fixed tube 2 is also sealed off by an optical device forming a window 23a.

La tube fixe 2 est centré dans un palier de guidage 26 fixé par tout moyen approprié à l'intérieur du tube mobile 3 à l'extrémité inférieure du carénage 5. Selon une variante de réalisation, le palier 26 peut également être rendu solidaire du tube fixe 2.The fixed tube 2 is centered in a guide bearing 26 fixed by any appropriate means inside the movable tube 3 at the lower end of the fairing 5. According to an alternative embodiment, the bearing 26 can also be made integral with the tube fixed 2.

Comme on le voit plus particulièrement à la Figure 4, le palier 26 présente une structure lamifiée qui lui procure une aptitude de "rotulage", c'est à dire autorise sa déformation dans les trois directions de l'espace.As can be seen more particularly in FIG. 4, the bearing 26 has a laminated structure which gives it the ability to "swivel", that is to say allows its deformation in the three directions of space.

Le palier 26 est ainsi réalisé sous la forme d'un empilage de lames 26a en forme de coupelles alternativement métalliques et en matière synthétique, la coupelle 26a adjacente au carénage 5 étant métallique tandis que la coupelle 26a adjacente au tube fixe étant en matière synthétique. On réalise ainsi un dispositif simple qui permet d'une part un coulissement entre le tube fixe 2 et le tube mobile 3 et d'autre part de remédier aux défauts d'alignement et aux déformations du carénage 5 dues aux contraintes appliquées sur celui-ci.The bearing 26 is thus produced in the form of a stack of blades 26a in the form of cups alternately metallic and made of synthetic material, the cup 26a adjacent to the fairing 5 being metallic while the cup 26a adjacent to the fixed tube being made of synthetic material. A simple device is thus produced which allows on the one hand a sliding between the fixed tube 2 and the movable tube 3 and on the other hand to remedy the misalignments and deformations of the fairing 5 due to the stresses applied on it .

Selon une autre caractéristique avantageuse de l'invention, l'étanchéité à l'eau entre le carénage 5 et le tube fixe 2 est réalisée au moyen d'une membrane 27 compressible suivant l'axe X-X′ des tubes fixe 2 et mobile 3 et rendue solidaire du tube fixe 2. Comme on le voit plus particulièrement à la Figure 5, la membrane 27 comprend plusieurs éléments de membrane 27a, de préférence en acier inoxydable qui résiste bien à la corrosion, reliés entre eux par des brides 27b munies chacune d'un joint d'étanchéité annulaire 27c. La membrane 27, conformée en soufflet, assure l'étanchéité de l'ensemble optique fixe qui est par ailleurs soumis à la pression d'immersion. Afin d'éviter l'écrasement de cette membrane, celle-ci est rendue solidaire du tube fixe 2 par l'intermédiaire d'anneaux de centrage 27d prévus à cet effet le long du tube fixe 2.According to another advantageous characteristic of the invention, the watertightness between the fairing 5 and the fixed tube 2 is achieved by means of a membrane 27 compressible along the axis XX ′ of the fixed 2 and mobile 3 tubes and made integral with the fixed tube 2. As can be seen more particularly in FIG. 5, the membrane 27 comprises several membrane elements 27a, preferably made of stainless steel which resists corrosion well, connected together by flanges 27b each provided with an annular seal 27c. The membrane 27, shaped as a bellows, seals the fixed optical assembly which is also subjected to the immersion pressure. In order to avoid crushing of this membrane, the latter is made integral with the fixed tube 2 by means of centering rings 27d provided for this purpose along the fixed tube 2.

L'extrémité supérieure du carénage 5 supporte également des antennes externes 28 de détection d'émissions radar et/ou de navigation par satellite.The upper end of the fairing 5 also supports external antennas 28 for radar emission detection and / or satellite navigation.

En fonction de la course de hissage à obtenir et de la hauteur disponible à l'intérieur de l'abri de navigation 4 du véhicule porteur, on peut envisager une conception du mât 1 à deux tubes mobiles concentriques dont l'étanchéité serait réalisée au moyen d'un dispositif analogue à la membrane 27 précitée. Dans ce cas, le carénage 5 coulisserait dans un dispositif intermédiaire qui serait lui-même guidé dans l'abri de navigation 4, le hissage du dispositif intermédiaire étant obtenu par une presse disposée entre les deux tubes concentriques précités.Depending on the hoisting stroke to be obtained and the height available inside the navigation shelter 4 of the carrier vehicle, it is possible to envisage a design of the mast 1 with two concentric mobile tubes, the sealing of which would be achieved by means of a device similar to the aforementioned membrane 27. In this case, the fairing 5 would slide in an intermediate device which would itself guided in the navigation shelter 4, the hoisting of the intermediate device being obtained by a press disposed between the two aforementioned concentric tubes.

Selon une première variante de réalisation de l'invention représentée à la Figure 2, la coiffe 14 et la tête optique 12 ne forment qu'un seul et même élément 30 monté à rotation autour de l'axe X-X′ des tubes fixe 2 et mobile 3. Les moyens d'entraînement de cet élément 30 et d'étanchéité entre cet élément 30 et le carénage 5, repérés 15a à la Figure 2, sont de conception identique aux moyens 15 de la Figure 1.According to a first alternative embodiment of the invention shown in Figure 2, the cap 14 and the optical head 12 form one and the same element 30 mounted for rotation about the axis XX ′ of the fixed 2 and mobile tubes 3. The means for driving this element 30 and for sealing between this element 30 and the fairing 5, marked 15a in FIG. 2, are of identical design to the means 15 in FIG. 1.

En général, un sous-marin comporte deux mâts périscopiques. Dans le cas de deux mâts périscopiques de type purement optique, l'invention a prévu un seul poste opérateur 22 pour les deux mâts périscopiques (voir Figure 3). Selon cette variante de réalisation, le tube fixe de chaque mât 1 est prolongé par un tube coudé à 90° 35, les parties horizontales de chaque tube coudé 35 de chaque mât 1 s'étendant dans le prolongement l'une de l'autre. Le transfert vers le poste opérateur 22 des faisceaux optiques émanant de chacun des mâts 1 après réflexion à 90° par un miroir 36 est réalisé sélectivement par permutation d'un miroir 37 situé à l'intersection des faisceaux optiques émanant de chaque mât. Toujours selon cette configuration, les différentes commandes des deux mâts périscopiques pourront être regroupées sur le poste opérateur 22.In general, a submarine has two periscopic masts. In the case of two periscopic masts of the purely optical type, the invention has provided a single operator station 22 for the two periscopic masts (see FIG. 3). According to this alternative embodiment, the fixed tube of each mast 1 is extended by a tube bent at 90 ° 35, the horizontal parts of each bent tube 35 of each mast 1 extending in the extension of one another. The transfer to the operator station 22 of the optical beams emanating from each of the masts 1 after reflection at 90 ° by a mirror 36 is carried out selectively by permutation of a mirror 37 located at the intersection of the optical beams emanating from each mast. Still according to this configuration, the various commands of the two periscopic masts can be grouped on the operator station 22.

On va maintenant décrire en détail, en référence aux Figures 6 et 7, les moyens 15 d'étanchéité entre la coiffe 14 et le tête optique 12 en regard du plan de joint entre la coiffe 14 et le carénage 5 et d'entraînement en rotation de cette coiffe 14, et les moyens 15a d'entraînement de l'élément 30 et d'étanchéité entre cet élément 30 et le carénage 5.We will now describe in detail, with reference to Figures 6 and 7, the sealing means 15 between the cap 14 and the optical head 12 opposite the plane of joint between the cap 14 and the fairing 5 and rotational drive of this cap 14, and the means 15a for driving the element 30 and sealing between this element 30 and the fairing 5.

A la Figure 6, on voit qu'entre la coiffe 14 et le tube 3, est interposé un joint électrique tournant 15 qui comprend un élément de joint fixe dit statorique monté en appui contre la face intérieure de l'extrémité du tube 3, et un élément de joint rotatif dit rotorique qui entoure avec jeu la tête 12. L'élément de joint rotorique est rendu solidaire en rotation de la coiffe 14 au moyen d'un doigt d'entraînement 41 qui relie la coiffe 14 et l'élément de joint rotorique. Entre les éléments de joint statorique et rotorique sont interposés un double joint d'étanchéité annulaire 15b et un ensemble 15c formant roulements et collecteur électrique tournant pour l'alimentation des équipements électriques de la tête 12 au moyen d'une liaison souple d'alimentation 61 dite trainard d'alimentation. Un moteur 48 et des roulements 47 permettent l'entraînement en rotation de la coiffe 14. Un capteur de position 49 est prévu pour déterminer la position angulaire de la tête 12 par rapport à la coiffe 14.In Figure 6, we see that between the cap 14 and the tube 3, there is interposed a rotary electrical seal 15 which comprises a fixed seal element called stator mounted in abutment against the internal face of the end of the tube 3, and a rotary seal element said rotor which surrounds with play the head 12. The rotor seal element is made to rotate with the cover 14 by means of a drive finger 41 which connects the cover 14 and the rotor seal element. Between the stator and rotor seal elements are interposed a double annular seal 15b and a set 15c forming bearings and rotating electrical collector for the supply of electrical equipment to the head 12 by means of a flexible supply link 61 so-called feeding trainer. A motor 48 and bearings 47 allow the cap 14 to rotate. A position sensor 49 is provided for determining the angular position of the head 12 relative to the cap 14.

Entre une face interne de l'extrémité supérieure du carénage 5 et la coiffe 14 sont interposés un premier joint d'étanchéité annulaire 42 gonflable dont le taux de gonflage est proportionnel à la pression d'immersion, un second joint d'étanchéité 43, un moteur 44 d'entraînement en rotation de la coiffe 14 et un capteur de position 45 pour déterminer la position angulaire de la coiffe 14 par rapport à la tête 12. Entre la coiffe 14 et la face externe de l'extrémité du tube 3 sont interposés des roulements 46 qui permettent la rotation de la coiffe 14.Between an internal face of the upper end of the fairing 5 and the cover 14 are interposed a first annular seal 42 inflatable whose inflation rate is proportional to the immersion pressure, a second seal 43, a motor 44 for driving the cap 14 in rotation and a position sensor 45 for determining the angular position of the cap 14 relative to the head 12. Between the cap 14 and the external face of the end of the tube 3 are interposed bearings 46 which allow rotation of the cap 14.

Les moteurs d'entraînement en rotation 44 et 48 ainsi que les capteurs de position angulaire 45 et 49 sont reliés aux moyens électroniques d'asservissement disposés dans le compartiment 16 par l'intermédiaire d'une prise d'alimentation 57.The rotational drive motors 44 and 48 as well as the angular position sensors 45 and 49 are connected to the electronic control means arranged in the compartment 16 by means of a power outlet 57.

En variante, les capteurs 45 et 49 peuvent être remplacés par un capteur unique 52 qui est interposé entre l'extrémité supérieure de la tête 12 et la coiffe 14 pour une mesure directe de l'écart de position angulaire entre la coiffe 14 et la tête 12. Les moyens précités permettent en particulier de réaliser un mât 1 équipé d'une coiffe 14 dite suiveuse en permettant la "recopie" de la position de la structure interne de la tête optique 12 et l'alignement du hublot 51 de la coiffe 14 avec les axes optiques des voies du mât 1.As a variant, the sensors 45 and 49 can be replaced by a single sensor 52 which is interposed between the upper end of the head 12 and the cap 14 to a direct measurement of the difference in angular position between the cap 14 and the head 12. The aforementioned means make it possible in particular to produce a mast 1 equipped with a cap 14, called a follower, allowing the "copying" of the position of the structure internal of the optical head 12 and the alignment of the porthole 51 of the cover 14 with the optical axes of the tracks of the mast 1.

A la Figure 7, on voit que sont interposés entre la coiffe 30 et la face interne de l'extrémité supérieure du tube 3, un joint électrique tournant 15a dont la structure est sensiblement identique à celle du joint électrique tournant 15 décrit en référence à la Figure 6, un moteur 54 d'entraînement en rotation de l'élément 30, un capteur de position angulaire 55 de l'élément 30 et des roulements 53 qui permettent la rotation de l'élément 30. Le joint électrique tournant 15a présente la particularité d'être rempli d'huile dont la pression est équilibrée avec la pression d'immersion du mât. Le capteur de position angulaire 55 est relié à une prise 60 de liaison de commande du moteur 54 en position qui est lui-même relié à prise 60 tandis que l'élément 30 comporte une prise d'alimentation 58 de ces équipements électriques elle-même reliée à une prise 59 de liaison vers le bord du véhicule sous-marin. Plus explicitement, les prises 60 et 59 sont reliées aux consoles d'exploitation 32 du sous-marin.In Figure 7, we see that are interposed between the cap 30 and the inner face of the upper end of the tube 3, a rotating electrical joint 15a whose structure is substantially identical to that of the rotating electrical joint 15 described with reference to the Figure 6, a motor 54 for driving the element 30 in rotation, an angular position sensor 55 for the element 30 and bearings 53 which allow the element 30 to rotate. The rotating electrical joint 15a has the particularity to be filled with oil whose pressure is balanced with the immersion pressure of the mast. The angular position sensor 55 is connected to a socket 60 for controlling the motor 54 in position which is itself connected to socket 60 while the element 30 comprises a supply socket 58 for these electrical equipment items itself connected to a socket 59 for connection to the edge of the underwater vehicle. More explicitly, the sockets 60 and 59 are connected to the operating consoles 32 of the submarine.

L'élément rotorique de joint tournant est par ailleurs rendu solidaire de l'élément 30 au moyen d'un bras 56.The rotary element of the rotary joint is also made integral with the element 30 by means of an arm 56.

Les équipements précités permettent ainsi d'asservir en position, à distance depuis les consoles 32, l'élément 30.The aforementioned equipment thus allows the element 30 to be controlled in position, remotely from the consoles 32.

La structure télescopique des mâts conforme à l'invention permet essentiellement la réalisation d'une vision optique sans pénétration d'éléments hissables à l'intérieur de la coque épaisse du sous-marin, une souplesse d'aménagement du local opérationnel parallèlement à une opération à poste fixe, la réduction des masses dans la partie supérieure de l'abri de navigation, l'augmentation de la stabilité du véhicule porteur, la réduction du maître couple de l'abri de navigation du fait de la suppression des paliers de guidage ce qui diminue la résistance à l'avancement et augmente par ailleurs la discrétion acoustique et finalement une simplification sensible des circuits hydrauliques de commande des mâts.The telescopic structure of the masts according to the invention essentially allows the realization of an optical vision without penetration of hoisting elements inside the thick hull of the submarine, flexibility in fitting out the operational space in parallel with a fixed station operation, reducing the masses in the upper part of the navigation shelter, increasing the stability of the carrier vehicle, reducing the main torque of the shelter navigation due to the removal of the guide bearings which reduces the resistance to advancement and also increases the acoustic discretion and finally a significant simplification of the hydraulic control circuits of the masts.

Les signes de référence insérés après les caractéristiques techniques mentionnées dans les revendications ont pour seul but de faciliter la compréhension de ces dernières et n'en limitent aucunement la portée.The reference signs inserted after the technical characteristics mentioned in the claims are intended only to facilitate the understanding of the latter and in no way limit their scope.
