Abstract

For ensuring the relief of multi-directional tractive forces exerted on a cable (12), one end of which is fastened to a connector (13), at least one turn of the cable is wound onto a reel (22) which is placed in direct proximity to the connector. In particular, the cable (12) can connect a wire-guided missile to a firing station carrying the connector (13) and the reel (22). During the transport of the missile, clamping parts (26, 34) temporarily connect a support (24) carrying the reel (22) and the connector (13) to the missile. <IMAGE>

Description

L'invention concerne un dispositif conçu pour assurer la reprise des efforts de traction susceptibles d'être appliqués, selon une direction variable, sur un câble dont une extrémité est fixée à un connecteur et dont l'extrémité opposée est liée à un engin filoguidé.The invention relates to a device designed to ensure the recovery of the tensile forces which can be applied, in a variable direction, to a cable, one end of which is fixed to a connector and the opposite end of which is linked to a wire-guided vehicle.

Une application privilégiée du dispositif de reprise d'efforts selon l'invention concerne le cas des engins filoguidés. Cette terminologie désigne ici aussi bien les engins reliés à un poste de tir par une fibre optique que les engins reliés à un poste de tir par un câble électrique ou électro-optique. Par ailleurs, le poste de tir peut être de forme quelconque, c'est-à-dire qu'il peut comprendre notamment une rampe de lancement, un conteneur de lancement, etc..A preferred application of the force recovery device according to the invention relates to the case of wire-guided vehicles. This terminology designates here as well the machines connected to a shooting station by an optical fiber as the machines connected to a shooting station by an electric or electro-optical cable. Furthermore, the firing station may be of any shape, that is to say that it may in particular comprise a launching ramp, a launching container, etc.

Sur les engins filoguidés, et comme l'illustre schématiquement la figure 1, le câble 2 qui relie l'engin 1 au poste de tir est initialement bobiné dans une région arrière de l'engin. Une extrémité du câble 2 est liée au système de détection embarqué sur l'engin alors que l'autre extrémité est liée à l'instrumentation du poste de tir par l'intermédiaire d'un connecteur approprié 3 dont le raccordement est effectué lorsque l'engin est mis en place.On wire-guided devices, and as illustrated diagrammatically in FIG. 1, the cable 2 which connects the device 1 to the shooting station is initially wound in a rear region of the device. One end of the cable 2 is linked to the detection system on board the machine while the other end is linked to the instrumentation of the shooting station by means of an appropriate connector 3 whose connection is made when the gear is set up.

Après le lancement de l'engin et pendant toute la durée du vol, le câble 2 se dévide de la bobine située dans la région arrière de l'engin 1. La partie du câble 2 située entre l'engin et le poste de tir est alors soumise à un effort de traction dont la direction varie en fonction de l'éloignement de l'engin et de la position du câble sur la périphérie de la bobine. Cet effort a en partie pour origine le débobinage du câble. Il est accentué par le fait que les spires formant la bobine de câble sont habituellement collées entre elles pour éviter un débobinage prématuré et mal contrôlé. Le débobinage du câble s'accompagne donc de l'arrachage de la colle, ce qui augmente l'effort de traction appliqué sur le câble.After launching the device and throughout the duration of the flight, the cable 2 unwinds from the reel located in the rear region of the device 1. The part of the cable 2 located between the device and the shooting station is then subjected to a tensile force, the direction of which varies as a function of the distance of the machine and the position of the cable on the periphery of the coil. This effort is partly due to the unwinding of the cable. It is accentuated by the fact that the turns forming the cable reel are usually glued together to avoid premature and poorly controlled unwinding. The unwinding of the cable is therefore accompanied by the removal of the adhesive, which increases the tensile force applied to the cable.

Dans la configuration habituelle illustrée sur la figure 1, ainsi que dans le document EP-A-0 507 430, cet effort de traction F, de direction variable, est exercé directement sur le connecteur 3 par le câble 2. L'extrémité du câble 2 fixée sur le connecteur 3 supporte donc à la fois des efforts de traction et des efforts de flexion alternés. Ces deux types d'efforts risquent d'entraîner la rupture du câble, compte tenu notamment de la très faible section présentée par celui-ci.In the usual configuration illustrated in FIG. 1, as well as in document EP-A-0 507 430, this tensile force F, of variable direction, is exerted directly on the connector 3 by the cable 2. The end of the cable 2 fixed on the connector 3 therefore supports both traction forces and alternating bending forces. These two types of force risk causing the cable to break, especially given the very small section presented by it.

Dans le cas particulier où le câble 2 est constitué par une fibre optique, ces problèmes mécaniques sont particulièrement aigus. De plus, Il vient s'y ajouter une atténuation importante des données transmises entre l'engin et le poste de tir, du fait du très faible rayon de courbure présenté par la fibre à l'endroit où elle est raccordée sur le connecteur 3.In the particular case where the cable 2 is constituted by an optical fiber, these mechanical problems are particularly acute. In addition, there is a significant attenuation of the data transmitted between the machine and the shooting station, due to the very small radius of curvature presented by the fiber at the place where it is connected to the connector 3.

Dans le document US-A-3 245 127, qui décrit le préambule de la revendication 1, il est proposé de reprendre les efforts de traction appliqués sur le câble d'un engin filoguidé, à proximité de connecteurs portés par le poste de tir, au moyen d'un bobineau sur lequel sont enroulés plusieurs spires du câble. Le maintien de ces spires sur le bobineau est assuré en les noyant dans un bloc de matière plastique telle que du caoutchouc synthétique.In document US-A-3,245,127, which describes the preamble of claim 1, it is proposed to take up the tensile forces applied to the cable of a wire-guided vehicle, close to connectors carried by the shooting station, by means of a spool on which are wound several turns of the cable. The holding of these turns on the reel is ensured by drowning them in a block of plastic material such as synthetic rubber.

Si le dispositif de reprise d'efforts décrit dans ce document permet de préserver le câble lors du lancement, il ne supprime pas totalement le risque de rupture du câble lors du stockage et du transport de l'engin, avant qu'il ne soit installé sur le poste de tir, notamment lorsque le câble est une fibre optique.If the force recovery device described in this document makes it possible to preserve the cable during launching, it does not completely eliminate the risk of cable breakage during storage and transport of the machine, before it is installed. on the shooting station, especially when the cable is an optical fiber.

Par ailleurs, le document GB-A-2 175 038 décrit un adaptateur permettant le montage simultané d'une torpille filoguidée et d'une bobine portant le câble dans un tube lance torpille. L'adaptateur est conçu afin d'éviter que la queue de la torpille ne supporte des efforts non axiaux. Lors du lancement, l'adaptateur libère la torpille, alors que la bobine reste dans le tube lance torpille.Furthermore, document GB-A-2 175 038 describes an adapter allowing the simultaneous mounting of a wire-guided torpedo and a coil carrying the cable in a torpedo tube. The adapter is designed to prevent the tail of the torpedo from supporting non-axial forces. During launch, the adapter releases the torpedo, while the coil remains in the torpedo tube.

L'invention a précisément pour objet un dispositif de reprise d'efforts de traction appliqués sur un câble d'engin filoguidé, conçu de façon à préserver l'intégrité du câble aussi bien pendant le lancement de l'engin que pendant son stockage et son transport.The subject of the invention is precisely a device for taking up tensile forces applied to a wire-guided vehicle cable, designed so as to preserve the integrity of the cable both during the launching of the vehicle and during its storage and transport.

Conformément à l'invention, ce résultat est obtenu au moyen d'un dispositif de reprise d'efforts de traction susceptibles d'être appliqués, selon une direction variable, sur un câble bobiné sur un engin filoguidé, apte à être lancé depuis un poste de tir portant une partie d'un connecteur, à laquelle est fixée une extrémité du câble, ce dispositif comprenant un bobineau monté à proximité du connecteur et sur lequel est enroulée au moins une spire du câble et un support portant le bobineau, caractérisé par le fait que le support porte également ladite partie du connecteur, au moins une première pièce de bridage étant apte à relier le support à l'engin pendant le stockage et le transport de ce dernier.In accordance with the invention, this result is obtained by means of a device for taking up tensile forces which can be applied, in a variable direction, to a cable wound on a wire-guided vehicle, capable of being launched from a station. of firing carrying a part of a connector, to which one end of the cable is fixed, this device comprising a reel mounted near the connector and on which is wound at least one turn of the cable and a support carrying the reel, characterized by fact that the support also carries said part of the connector, at least one first clamping part being able to connect the support to the machine during storage and transport of the latter.

Le bobineau et le connecteur comportent de préférence des axes sensiblement orthogonaux, l'axe du connecteur étant tangent à la surface périphérique du bobineau.The coil and the connector preferably have substantially orthogonal axes, the axis of the connector being tangent to the peripheral surface of the coil.

Si l'effort appliqué sur la câble est trop important et/ou s'il se présente sous la forme de chocs, le bobineau est avantageusement monté sur le support par l'intermédiaire d'un système amortisseur.If the force applied to the cable is too great and / or if it is in the form of shocks, the spool is advantageously mounted on the support by means of a damping system.

Par ailleurs, dans le cas où l'angle formé entre l'axe du connecteur et la partie du câble située à l'opposé du connecteur par rapport au bobineau est trop important, le bobineau est avantageusement monté sur le support par l'intermédiaire d'une structure articulée.Furthermore, in the case where the angle formed between the axis of the connector and the part of the cable situated opposite the connector with respect to the spool is too large, the spool is advantageously mounted on the support by means of 'an articulated structure.

De préférence, la ou les spires du câble enroulées sur le bobineau sont maintenues par un film de colle.Preferably, the turn or turns of the cable wound on the reel are held by a film of adhesive.

En outre, la surface périphérique du bobineau comporte, par exemple sur les 3/4 de sa périphérie, un filetage dans lequel est reçu le câble. Ce filetage facilite le maintien latéral du câble sur le bobineau.In addition, the peripheral surface of the spool comprises, for example on 3/4 of its periphery, a thread in which the cable is received. This thread facilitates lateral retention of the cable on the spool.

Lorsque la ou les spires du câbles ont été enroulées sur le bobineau, celui-ci peut être recouvert d'un capot.When the cable coil (s) have been wound on the spool, the latter can be covered with a cover.

Avantageusement, la partie du câble située entre le missile et le bobineau, qui est de préférence maintenue lâche, est soutenue par un guide-câble supporté par la première pièce de bridage.Advantageously, the part of the cable located between the missile and the spool, which is preferably kept loose, is supported by a cable guide supported by the first clamping piece.

Pendant le stockage et le transport de l'engin, la première pièce de bridage est prévue pour être fixée par des sangles sur une enveloppe de protection de l'engin, entourant la bobine de câble.During storage and transport of the machine, the first clamping piece is intended to be fixed by straps to a protective casing of the machine, surrounding the cable reel.

Avantageusement, le dispositif de reprise d'efforts selon l'invention comprend en outre une deuxième pièce de bridage constituée par un couvercle de protection interposé entre l'engin et le support.Advantageously, the force recovery device according to the invention further comprises a second clamping piece constituted by a protective cover interposed between the machine and the support.

Dans une forme de réalisation préférentielle de l'invention, le câble est une fibre optique équipée d'une gaine de protection dans sa partie fixée sur le connecteur et enroulée sur le bobineau, le connecteur étant un connecteur optique.In a preferred embodiment of the invention, the cable is an optical fiber fitted with a protective sheath in its part fixed to the connector and wound on the spool, the connector being an optical connector.

The latter can however take a different form and include, for example, a launch container in which the device is received.

Comme l'illustre plus précisément la figure 3, dans l'exemple considéré l'engin 10 est relié au poste de tir par un câble constitué par une fibre optique 12. La fibre optique 12 est enroulée sur une bobine 18 située à l'arrière de l'engin 10. Cette bobine de fibre optique 12, centrée sur l'axe longitudinal de l'engin 10, est disposée à l'intérieur d'une enveloppe 20 qui sert à protéger la fibre, la canaliser et limiter ses débattements ; seule la partie arrière convergente est illustrée sur la figure 3.As illustrated more precisely in FIG. 3, in the example considered the machine 10 is connected to the shooting station by a cable constituted by an optical fiber 12. The optical fiber 12 is wound on a reel 18 located at the rear of the machine 10. This optical fiber reel 12, centered on the longitudinal axis of the machine 10, is disposed inside an envelope 20 which serves to protect the fiber, channel it and limit its travel; only the converging rear part is illustrated in FIG. 3.

Une partie terminale de la fibre optique 12 sort de l'engin 10 par une ouverture centrale formée à l'arrière de l'enveloppe 20. L'extrémité de cette partie terminale est raccordée sur une partie 13a d'un connecteur optique 13, dont une partie 13b est reliée à une installation (non représentée) de pilotage à distance implantée sur le poste de tir. La partie terminale de la fibre optique 12 est généralement équipée d'une gaine de protection sur quelques mètres. Cependant, l'invention s'applique également au cas d'une fibre optique non protégée.A terminal part of the optical fiber 12 leaves the machine 10 through a central opening formed at the rear of the casing 20. The end of this terminal part is connected to a part 13a of an optical connector 13, of which a part 13b is connected to an installation (not shown) for remote control located on the shooting station. The terminal part of the optical fiber 12 is generally equipped with a protective sheath over a few meters. However, the invention also applies in the case of unprotected optical fiber.

Conformément à l'invention, on interpose entre le connecteur optique 13 et l'extrémité arrière de l'engin 10 un dispositif de reprise d'efforts conçu pour supporter, à la place du connecteur optique 13, les efforts de traction multidirectionnels appliqués sur la fibre optique 12 après le lancement de l'engin.According to the invention, there is interposed between the optical connector 13 and the rear end of the machine 10 a force recovery device designed to support, in place of the optical connector 13, the multidirectional tensile forces applied to the fiber optic 12 after the launch of the machine.

Ce dispositif de reprise d'efforts permet de supprimer tout risque de rupture de la fibre optique 12 à l'endroit où elle est fixée sur le connecteur optique 13. Il permet en outre, pendant les phases d'intégration, de manutention, de stockage et de transport préalables au lancement, de protéger la fibre optique. Enfin, le dispositif de reprise d'efforts selon l'invention empêche que les signaux optiques transmis par la fibre optique ne fassent l'objet d'une atténuation importante, du fait d'une courbure trop forte de la fibre à l'endroit où elle est attachée sur le connecteur.This effort recovery device eliminates any risk of breakage of the optical fiber 12 at the place where it is fixed on the optical connector 13. It also makes it possible, during the integration, handling and storage phases. and transport prior to launch, to protect the optical fiber. Finally, the force recovery device according to the invention prevents the optical signals transmitted by the optical fiber from being subject to a significant attenuation, due to a too strong curvature of the fiber at the place where it is attached to the connector.

Comme l'illustrent les figures 3 et 4, ce dispositif de reprise d'efforts comprend un bobineau 22 qui est fixé sur un support 24 portant également le connecteur optique 13. Le support 24 est prévu pour être fixé, par exemple au moyen de vis 36, sur la rampe 14 du poste de tir. Dans ces conditions, l'axe du connecteur optique 13 est orienté parallèlement à l'axe de l'engin 10. Le bobineau 22 est alors placé devant le connecteur 13 et à proximité immédiate de celui-ci. De plus, le bobineau 22 est orienté de telle sorte que son axe soit orthogonal à l'axe du connecteur et que ce dernier axe soit sensiblement tangent à la surface périphérique 22a du bobineau 22.As illustrated in Figures 3 and 4, this force recovery device comprises a coil 22 which is fixed on a support 24 also carrying the optical connector 13. The support 24 is designed to be fixed, for example by means of screws 36, on ramp 14 of the shooting station. Under these conditions, the axis of the optical connector 13 is oriented parallel to the axis of the machine 10. The reel 22 is then placed in front of the connector 13 and in the immediate vicinity thereof. In addition, the coil 22 is oriented so that its axis is orthogonal to the axis of the connector and that the latter axis is substantially tangent to the peripheral surface 22a of the coil 22.

Afin que le bobineau 22 assure la reprise des efforts de traction multidirectionnels appliqués sur la fibre optique 12, la partie terminale de cette dernière située entre l'extrémité arrière de l'engin 10 et le connecteur 13 est enroulée sur une longueur d'au moins une spire sur le bobineau 22. Dans la pratique, deux ou trois spires de la fibre optique 12 peuvent être enroulées sur le bobineau 22. La mise en place de la fibre optique 12 sur le bobineau 22 est réalisée de telle sorte que la partie de la fibre optique 12 située entre le bobineau et l'extrémité arrière de l'engin 10 soit relativement lâche, pour faciliter la mise en place globale.So that the bobbin 22 ensures the recovery of the multidirectional tensile forces applied to the optical fiber 12, the terminal part of the latter located between the rear end of the machine 10 and the connector 13 is wound over a length of at least one turn on the reel 22. In practice, two or three turns of the optical fiber 12 can be wound on the reel 22. The positioning of the optical fiber 12 on the bobbin 22 is made in such a way that the part of the optical fiber 12 located between the bobbin and the rear end of the machine 10 is relatively loose, to facilitate overall positioning.

Pour maintenir la fibre optique 12 sur le bobineau 22, on utilise avantageusement un film de colle. De plus, le positionnement latéral de la ou des spires formées par la fibre optique 12 autour du bobineau 22 est assuré avantageusement par la réalisation d'un filetage de profil semi-circulaire sur les 3/4 de la surface périphérique 22a du bobineau.To maintain the optical fiber 12 on the spool 22, an adhesive film is advantageously used. In addition, the lateral positioning of the turn (s) formed by the optical fiber 12 around the reel 22 is advantageously ensured by the production of a semicircular profile thread on 3/4 of the peripheral surface 22a of the reel.

Le diamètre du bobineau 22 est choisi suffisamment grand pour que le rayon de courbure de la fibre optique 12 n'entraîne pas d'atténuation du signal transmis par cette fibre. Un diamètre de 50 mm peut notamment être adopté.The diameter of the spool 22 is chosen to be large enough so that the radius of curvature of the optical fiber 12 does not attenuate the signal transmitted by this fiber. In particular, a diameter of 50 mm can be adopted.

Par ailleurs, le bobineau 22 est fermé par un capot 38 fixé sur le bobineau par des vis 40. Ce capot 38 recouvre le bobineau 22 sur la majeure partie de sa circonférence, à l'exception de la zone située en face du connecteur optique 13 et d'une zone plus large située du côté de l'extrémité arrière de l'engin et dont l'ouverture prend en compte les différents changements de direction susceptibles d'intervenir sur la fibre 12 après le lancement de l'engin.Furthermore, the bobbin 22 is closed by a cover 38 fixed to the bobbin by screws 40. This cover 38 covers the bobbin 22 over most of its circumference, with the exception of the zone situated opposite the optical connector 13 and a wider area located on the side of the rear end of the machine and the opening of which takes into account the different changes of direction likely to occur on the fiber 12 after the launch of the machine.

Au cours des différentes manutentions (transport, stockage, etc.) qui précèdent son installation sur le poste de tir, l'extrémité de la fibre optique 12 est déjà fixée sur le connecteur optique 13 et une ou plusieurs spires de la partie de la fibre optique située entre le connecteur et l'extrémité arrière de l'engin sont enroulées sur le bobineau 22. Pour éviter que la fibre optique ne soit endommagée pendant ces phases de manutention, le dispositif de reprise d'efforts selon l'invention comprend aussi, avantageusement, des pièces de bridage permettant de relier le support 24 à l'engin et de protéger la fibre optique. Sur la figure 3, ces pièces de bridage sont représentées en traits mixtes.During the various handling operations (transport, storage, etc.) which precede its installation on the shooting station, the end of the optical fiber 12 is already fixed on the optical connector 13 and one or more turns of the part of the fiber optic located between the connector and the rear end of the machine is wound on the spool 22. To prevent the optical fiber from being damaged during these handling phases, the force recovery device according to the invention also advantageously comprises clamping pieces making it possible to connect the support 24 to the craft and protect the optical fiber. In Figure 3, these clamping parts are shown in phantom.

Une première pièce de bridage, désignée par la référence 26 sur les figures 3 et 4, comporte des pattes 26a prévues pour venir s'appliquer sur la partie arrière convergente de l'enveloppe 20, pour y être fixée provisoirement par des sangles (non représentées). Cette première pièce de bridage 26 se prolonge vers l'arrière pour être reliée au support 24, par exemple au moyen de vis 28.A first clamping part, designated by the reference 26 in FIGS. 3 and 4, comprises lugs 26a intended to come to bear on the converging rear part of the casing 20, to be fixed there temporarily by straps (not shown ). This first clamping piece 26 extends rearward to be connected to the support 24, for example by means of screws 28.

Afin d'assurer un guidage de la partie non tendue de la fibre optique 12 située entre l'extrémité arrière de l'engin 10 et le bobineau 22, la première pièce de bridage 26 supporte au moins un guide-câble démontable 30. Ce guide-câble se présente sous la forme d'une fourche à deux branches dans laquelle la fibre optique 12 est maintenue par une pièce démontable telle qu'une goupille 32.In order to guide the non-stretched part of the optical fiber 12 located between the rear end of the machine 10 and the bobbin 22, the first clamping part 26 supports at least one removable cable guide 30. This guide -cable is in the form of a fork with two branches in which the optical fiber 12 is held by a removable part such as a pin 32.

Le dispositif selon l'invention comprend de plus une deuxième pièce de guidage constituée par un couvercle de protection 34 prévu pour être fixé à l'arrière de la bobine 18 et sur le support 24 par des vis telles que la vis 36 sur la figure 3, pour fermer l'espace dans lequel se trouvent la fibre optique 12 et le bobineau 22 pendant les phases préliminaires à l'installation de l'engin sur le poste de tir.The device according to the invention further comprises a second guide piece constituted by a protective cover 34 intended to be fixed to the rear of the coil 18 and on the support 24 by screws such as the screw 36 in FIG. 3 , to close the space in which the optical fiber 12 and the spool 22 are located during the preliminary phases to the installation of the machine on the shooting station.

La mise en place du dispositif de reprise d'efforts selon l'invention sur l'engin 10, avant son transport jusqu'au poste de tir s'effectue de la façon suivante.The establishment of the force recovery device according to the invention on the machine 10, before its transport to the shooting station is carried out as follows.

L'ensemble constitué par le bobineau 22, le support 24, la pièce de bridage 26 et le guide câble 30, préalablement assemblés, est fixé à l'aide de sangles sur la partie arrière convergente de l'enveloppe 20 de l'engin. On enroule alors sur deux ou trois tours la fibre gainée 12 autour du bobineau 22, en laissant un léger mou entre le bobineau et la bobine 18. Comme on l'a vu, la partie de la fibre optique 12 enroulée sur le bobineau 22 est maintenue par un léger film de colle ou un adhésif. La partie de la fibre optique 12 située entre le bobineau 22 et l'extrémité arrière de l'engin est placée dans le guide-câble 30 et la goupille 32 est mise en place.The assembly constituted by the bobbin 22, the support 24, the clamping piece 26 and the cable guide 30, previously assembled, is fixed using straps on the converging rear part of the envelope 20 of the machine. The sheathed fiber 12 is then wound over two or three turns around the reel 22, leaving a slight slack between the reel and the reel 18. As we have seen, the part of the optical fiber 12 wound on the reel 22 is held by a light film of glue or adhesive. The part of the optical fiber 12 located between the bobbin 22 and the rear end of the machine is placed in the cable guide 30 and the pin 32 is put in place.

L'opérateur effectue ensuite la mise à longueur de la fibre optique 12 avant d'en fixer l'extrémité sur le connecteur optique 13. Celui-ci est alors à son tour fixé sur le support 24. A compter de cet instant, le connecteur optique 13 n'a plus à être manipulé, ce qui réduit d'autant les risques d'endommagement de la fibre optique résultant de manipulations ultérieures.The operator then cuts the optical fiber 12 to length before fixing the end to the optical connector 13. The latter is then in turn fixed on the support 24. From this instant, the connector optics 13 no longer has to be manipulated, which therefore reduces the risk of damage to the optical fiber resulting from subsequent manipulations.

L'opérateur monte ensuite le capot 38 sur le bobineau 22, puis il met en place le couvercle de protection 34. Il est à noter que ce dernier présente avantageusement une trappe de visite (non représentée) pour toute intervention sur cette partie arrière de l'engin, notamment pour la liaison entre l'engin et le poste de tir.The operator then mounts the cover 38 on the reel 22, then he sets up the protective cover 34. It should be noted that the latter advantageously has an inspection hatch (not shown) for any intervention on this rear part of the 'machine, especially for the connection between the machine and the shooting station.

Lorsque les opérations qui viennent d'être décrites sont terminées, l'engin 10 peut être transporté, stocké et manipulé sans que cela entraîne aucun risque d'endommager la fibre optique 12.When the operations which have just been described are completed, the machine 10 can be transported, stored and handled without this entailing any risk of damaging the optical fiber 12.

Quand on désire l'installer l'engin 10 sur le poste de tir, l'engin 10 est présenté sous la rampe de lancement 14 (figure 1) juste après que le couvercle de protection 34 et le guide-câble 30 aient été démontés. Bien entendu, le démontage du guide-câble 30 est effectué après enlèvement de la goupille 32. L'engin est alors mis en place sous la rampe de lancement 14.When it is desired to install the machine 10 on the shooting station, the machine 10 is presented under the launching ramp 14 (FIG. 1) just after the protective cover 34 and the cable guide 30 have been removed. Of course, the disassembly of the cable guide 30 is carried out after removal of the pin 32. The machine is then placed under the launching pad 14.

Lorsque cette mise en place de l'engin est terminée, l'opérateur commence à fixer le support 24 sous la rampe de lancement 14 en utilisant, par exemple, la moitié des vis de fixation 36. On désolidarise alors la première pièce de bridage 26 du support 24 en enlevant les vis 28, avant de terminer la fixation du support 24 sous la rampe de lancement 14.When this positioning of the machine is finished, the operator begins to fix the support 24 under the launching ramp 14 using, for example, half of the fixing screws 36. The first clamping piece 26 is then separated. of the support 24 by removing the screws 28, before completing the fixing of the support 24 under the launching pad 14.

L'opérateur procède ensuite à l'enlèvement de la pièce de bridage 26 en retirant les sangles qui reliaient cette pièce à l'extrémité arrière convergente de l'enveloppe 20. L'engin est alors prêt à être lancé.The operator then proceeds to remove the clamping piece 26 by removing the straps which connected this piece to the converging rear end of the envelope 20. The machine is then ready to be launched.

Au cours de ces dernières manutentions, il est à noter que le connecteur 13 n'est jamais sollicité.During these last handling operations, it should be noted that the connector 13 is never used.

Lorsque le lancement est effectué, les efforts de traction qui sont exercés sur la fibre optique 12 du fait du déroulement de cette fibre de la bobine 18 et du collage de la fibre sur cette bobine, sont repris en totalité par le bobineau 22. La conception de ce bobineau permet d'assurer l'arrimage de la fibre optique 12 sans que celle-ci ne subisse en un point quelconque de sa longueur une pliure trop importante susceptible d'en entraîner la rupture par flexion ou d'atténuer de façon importante la transmission des signaux optiques. De plus, étant donné que la force de traction exercée sur la fibre optique 12 n'est pas transmise au connecteur optique 13, tout risque de rupture de la fibre par arrachement de l'extrémité de celle-ci fixée sur le connecteur est impossible. L'utilisation du bobineau 22 permet en outre de prendre en compte les changements de direction de la fibre 12 qui interviennent, du fait même de son déroulement au début du lancement, puis du fait de sa trajectoire par la suite.When the launch is carried out, the tensile forces which are exerted on the optical fiber 12 due to the unwinding of this fiber from the reel 18 and the bonding of the fiber on this reel, are entirely taken up by the reel 22. The design of this spool makes it possible to secure the optical fiber 12 without the latter undergoing at any point along its length an excessively large bend capable of causing it to rupture by bending or significantly attenuating the transmission of optical signals. In addition, since the tensile force exerted on the optical fiber 12 is not transmitted to the optical connector 13, any risk of breaking the fiber by tearing off the end of the latter fixed to the connector is impossible. The use of the bobbin 22 also makes it possible to take into account the changes in direction of the fiber 12 which occur, by the very fact of its course at the start of the launch, then due to its trajectory thereafter.

En variante, il est à noter qu'au lieu d'être fixé directement sur le support 24, le bobineau 22 peut être monté sur celui-ci par l'intermédiaire d'un système amortisseur, si l'effort de traction est trop élevé ou s'il est transmis sous forme de chocs.As a variant, it should be noted that instead of being fixed directly to the support 24, the bobbin 22 can be mounted on it by means of a damping system, if the traction force is too high or if it is transmitted in the form of shocks.

De plus, le bobineau 22 peut aussi être monté sur le support 24 par l'intermédiaire d'un système articulé lui permettant de s'orienter de telle sorte que le bobineau reste sensiblement dans le prolongement de la partie de la fibre optique située entre l'engin et le poste de tir. Ce système articulé est alors conçu pour que la partie de la fibre optique située entre le bobineau et le connecteur reste alignée avec l'axe de ce dernier.In addition, the bobbin 22 can also be mounted on the support 24 by means of an articulated system allowing it to orient itself so that the bobbin remains substantially in the extension of the part of the optical fiber situated between the and the shooting station. This articulated system is then designed so that the part of the optical fiber located between the coil and the connector remains aligned with the axis of the latter.
