Abstract

L'invention concerne un dispositif d'accouplement mécanique et électrique pour charges, notamment militaires. Un tel accouplement est constitué par la combinaison de moyens d'accrochage (70), de calage (12) et de liaison électrique agences de telle sorte que le verrouillage des moyens d'accrochage entraine simultanément et automatiquement sans qu'il soit nécessaire de faire appel à des opérations de réglage, le calage dans toutes les positions de la charge portée par rapport à la charge porteuse ainsi que leur liaison électrique. Une pluralité de charges peuvent ainsi être rendues solidaires les unes des autres en vue de leur emport sous un aéronef et être ensuite éjectées une à une en commençant par celle qui est la plus éloignée de cet aéronef.The invention relates to a mechanical and electrical coupling device for loads, in particular military. Such coupling consists of the combination of hooking means (70), wedging (12) and electrical connection agencies so that the locking of the hooking means leads simultaneously and automatically without the need to do call for adjustment operations, setting in all positions of the load carried with respect to the carrier load as well as their electrical connection. A plurality of loads can thus be made integral with one another with a view to carrying them under an aircraft and then be ejected one by one, starting with the one which is furthest from this aircraft.

Description

L'invention concerne un dispositif d'accouplement mécanique et électrique pour charges aéroportées, notamment militaires, telles que les projectiles. Elle concerne également les projectiles équipés de tels dispositifs.The invention relates to a mechanical and electrical coupling device for airborne loads, in particular military loads, such as projectiles. It also relates to projectiles equipped with such devices.

Plus précisément, l'invention concerne un tel dispositif d'accouplement capable d'assurer simultanément les fonctions d'accrochage et de calage d'une pluralité de charges, des projectiles, par exemple, en vue de leur emport sous aéronef, ainsi que leur éjection une par une en commençant par celle qui se trouve la plus éloignée de cet aéronef.More specifically, the invention relates to such a coupling device capable of simultaneously ensuring the hooking and chocking functions of a plurality of charges, projectiles, for example, with a view to carrying them under aircraft, as well as their ejection one by one, starting with the one that is furthest from this aircraft.

Un moyen d'emport de charges multiples sous avion consiste à accrocher à un polyone, solidaire de l'avion, une pièce intermédiaire généralement appelée "adaptateur" qui présente une pluralité d'emplacements d'accrochage pour les charges à transporter. A chacun de ces emplacements, sont installés les organes permettant, l'accrochage, le calage, la commande des sécurités, et l'éjection de la charge. Sur les avions volant aux vitesses actuelles, un système d'éjection de la charge. Sur les avions volant aux vitesses actuelles, un système d'éjection est en général installé dans l'adaptateur pour éjecter la charge vers le bas à une vitesse déterminée. A chaque emplacement, l'installation de la charge requiert successivement l'accrochage, puis le calage (généralement à l'aide de vis calage portées par des bras), enfin la liaison électrique ou mécanique avec les organes de commande de sécurité. L'éjecteur, généralement pyrotechnique, est inclus dans l'adaptateur à chaque emplacement. Il est actionné par un impulseur à poudre. Du fait que sur ces adaptateurs, il n'est possible d'accrocher et d'éjecter qu'une charge par emplacement, une mission nécessitant le largage successif d'un grand nombre de charges (par exemple un largage en chapelet) pose des problèmes considérables si le nombre de pylones n'est pas suffisant ou s'il convient d'en réserver certains pour d'autres usages.One means of carrying multiple loads under an aircraft consists in attaching an intermediate part, generally called an "adapter", to a polyone, integral with the aircraft, which has a plurality of hooking locations for the loads to be transported. At each of these locations, there are installed the devices allowing, the attachment, the setting, the safety controls, and the ejection of the load. On planes flying at current speeds, a load ejection system. On planes flying at current speeds, an ejection system is generally installed in the adapter to eject the load downwards at a determined speed. At each location, the installation of the load successively requires attachment, then wedging (generally using wedging screws carried by arms), finally electrical or mechanical connection with the safety control members. The ejector, usually pyrotechnic, is included in the adapter at each location. It is actuated by a powder impeller. Because on these adapters, it is only possible to hang and eject a load per location, a mission requiring the successive release of a large number of loads (for example a release in a chain) poses problems considerable if the number of pylons is not sufficient or if some should be reserved for other uses.

La présente invention a pour objet de pallier ces inconvénients et concerne un dispositif d'accouplement solidaire de chacune des charges comportant une combinaison de moyens coopérant entre eux pour accomplir les quatre fonctions essentielles suivantes à savoir : l'accrochage d'une charge à une autre, le calage de chacune des charges ainsi accrochées à la précédente, la liaison électrique nécessaire à la mise en oeuvre des séquenceurs équipant ces charges et l'éjection l'une après l'autre de ces charges ainsi superposées en commençant par la charge la plus éloignée de l'adaptateur.The object of the present invention is to overcome these drawbacks and relates to a coupling device integral with each of the loads comprising a combination of means cooperating with each other to accomplish the following four essential functions, namely: attachment of one load to another , the setting of each of the charges thus attached to the previous one, the electrical connection necessary for the implementation of the sequencers equipping these charges and the ejection one after the other of these charges thus superimposed, starting with the most charged away from the adapter.

La présente invention concerne plus précisément un dispositif d'accouplement mécanique et électrique pour charges, notamment militaires, en vue de leur emport sous aéronef, caractérisé en ce qu'il comprend une combinaison de moyens d'accrochage, de calage, de liaison électrique et d'éjection assurant l'accrochage mécanique d'une pluralité de charges de rangs successifs n, (n - 1), (n - 2) ... (n) étant le rang de la charge la plus éloignée de l'aéronef durant l'emport ; ces moyens coopérant entre eux pour, d'une part, assurer simultanément durant la phase d'accrochage et automatiquement sans opération de réglage, l'accouplement mécanique et l'accouplement électrique entre les différentes charges, pour, d'autre part, durant la phase de largage de ces charges à partir de l'aéronef, leur éjection une à une, celle de rang (n) étant éjectée seule et en première position, suivie de la charge de rang (n - 1) puis de la charge de rang (n - 2) et ainsi de suite.The present invention relates more precisely to a mechanical and electrical coupling device for loads, in particular military, with a view to carrying them under aircraft, characterized in that it comprises a combination of attachment means, wedging, electrical connection and ejection ensuring the mechanical attachment of a plurality of loads of successive ranks n, (n - 1), (n - 2) ... (n) being the rank of the most distant load from the aircraft during prevail; these means cooperating with one another, on the one hand, ensuring simultaneously during the attachment phase and automatically without adjustment operation, the mechanical coupling and the electrical coupling between the different loads, for, on the other hand, during the phase of dropping these loads from the aircraft, their ejection one by one, that of rank (n) being ejected alone and in first position, followed by the rank load (n - 1) then the rank load (n - 2) and so on.

Sur la figure 1, deux charges sont partiellement représentées, accrochées l'une à l'autre au moyen d'un dispositif d'accouplement conforme à l'invention. En fait ce nombre n'est pas limitatif, et une succession de charges peuvent ainsi être superposées. Il peut s'agir notamment de projectiles, tels que des bombes destinées à être transportées sous avions pour être larguées ensuite une à une. Les figures 2a et 2b représentent chacune un détail de la figure 1. La première et la seconde bombe 1 et 2 sont respectivement appelées bombe porteuse de rang (n - 1) et bombe portée de rang (n). Le nombre (n) est fonction des critères de résistance des matériaux et des contraintes mécaniques mis en jeu. Seulement une partie de ces bombes est représentée à l'exception de la partie avant (Av) et de la partie arrière (Ar). Le dispositif d'accouplement conforme à l'invention est référencé 20 de manière générale. Il comporte essentiellement une combinaison de moyens mécaniques d'accrochage et de calage, de moyens électriques de transfert des signaux de commande, et de moyen d'éjection. Il fait soit partie intégrante du corps de la charge (dans l'exemple décrit). Mais il peut être indépendant et est alors relié solidairement à celle-ci par tout moyen ne compromettant pas les qualités aérodynamiques de l'ensemble. Dans tous les cas, il est positionné au voisinage du centre de gravité de la charge.In Figure 1, two loads are partially shown, attached to each other by means of a coupling device according to the invention. In fact this number is not limiting, and a succession of charges can thus be superimposed. They may in particular be projectiles, such as bombs intended to be transported under airplanes to then be dropped one by one. FIGS. 2a and 2b each represent a detail of FIG. 1. The first and the second bomb 1 and 2 are respectively called carrier bomb of rank (n - 1) and bomb carried of rank (n). The number (n) depends on the resistance criteria of the materials and the mechanical stresses involved. Only part of these bombs is represented with the exception of the front part (Av) and the rear part (Ar). The coupling device according to the invention is generally referenced 20. It essentially comprises a combination of mechanical attachment and setting means, electrical means for transferring the control signals, and ejection means. It is an integral part of the body of the load (in the example described). But it can be independent and is then connected to it solidly by any means that does not compromise the aerodynamic qualities of the assembly. In all cases, it is positioned near the center of gravity of the load.

Les moyens d'accrochage et de calage comportent essentiellement un élément de liaison 70 reliant entre elles une partie mâle 3 et une partie femelle 6. La première partie, dans un exemple de réalisation comprend un cylindre pivotable 4 portant des billes 5 et un système de plots conducteurs 83 (figure 2b) dont la fonction sera décrite ultérieurement. La seconde partie 6 dite embase fixe comporte comme le montre la figure 2a, une cavité 7 délimitée par un rebord 8 interrompu par des alvéoles 9. Elle comporte également un jeu de plots mobiles bons conducteurs de l'électricité 82 destinés à coopérer, comme cela sera expliqué plus loin, avec les plots fixes 83 du cylindre pivotable. Le nombre et la disposition des billes 5 à la périphérie du cylindre d'accrochage 4 d'une part, la répartition des alvéoles 9 dans la cavité 7 d'autre part, sont tels que dans un premier temps le cylindre d'accrochage de la bombe portée ayant roté d'un certain angle, puisse être introduit à l'intérieur de la cavité 7 de la bombe 2 portée, les billes coïncidant alors avec les alvéoles 9 le long desquelles elles peuvent glisser et dans un second temps, le cylindre 4 porte-billes 5 ayant retrouvé sa position initiale, les billes 5 se trouvent supportées par le rebord 8 de la cavité 7 jouant alors un rôle de support pour les billes 5. L'accrochage entre la bombe 1 porteuse et la bombe 2 portée est ainsi assuré. Des premiers moyens 10 sont prévus pour assurer la rotation du cylindre d'accrochage 4, porte-billes 5, tandis que des seconds moyens 11 assurent le déplacement de coins de calage 12 destinés à coopérer avec les surfaces obliques d'un appui 13. La bombe portée se trouve alors calée dans les trois directions, grâce à l'action conjuguée de la liaison par le cylindre d'accrochage, des coins de calage et des premiers appuis 13 et des seconds appuis fixes 15 dont la forme épouse sensiblement celle du corps de la bombe. Comme cela sera expliqué ci-dessous, un logement 90 ménagé dans une équerre 111 est prévu pour recevoir une clé dont la rotation entrainera celle du cylindre 4 porte-billes 5.The hooking and wedging means essentially comprise a connecting element 70 connecting together a male part 3 and a female part 6. The first part, in an exemplary embodiment comprises a pivotable cylinder 4 carrying balls 5 and a system of conductive pads 83 (Figure 2b) whose function will be described later. The second part 6, called the fixed base comprises, as shown in FIG. 2a, a cavity 7 delimited by a flange 8 interrupted by cells 9. It also comprises a set of mobile pads good conductors of electricity 82 intended to cooperate, as will be explained below, with the fixed pads 83 of the pivotable cylinder. The number and the arrangement of the balls 5 at the periphery of the attachment cylinder 4 on the one hand, the distribution of the cells 9 in the cavity 7 on the other hand, are such that at first the attachment cylinder of the bomb carried having rotated by a certain angle, can be introduced inside the cavity 7 of the bomb 2 carried, the balls then coinciding with the cells 9 along which they can slide and in a second time, the cylinder 4 ball holder 5 having returned to its initial position, the balls 5 are supported by the rim 8 of the cavity 7 then playing a supporting role for the balls 5. The attachment between the carrier bomb 1 and the carrier bomb 2 is thus assured. First means 10 are provided for rotation of the attachment cylinder 4, ball holder 5, while second means 11 ensure the displacement of wedging wedges 12 intended to cooperate with the oblique surfaces of a support 13. The bomb carried is then wedged in three directions, thanks to the combined action of the connection by the attachment cylinder, wedging wedges and first supports 13 and second fixed supports 15 whose shape substantially matches that of the body the bomb. As will be explained below, a housing 90 formed in a bracket 111 is provided for receiving a key whose rotation will cause that of the cylinder 4 ball holder 5.

Ces différents moyens sont maintenant décrits plus en détail au moyen des figures suivantes et plus particulièrement des figures 3 à 7.These different means are now described in more detail by means of the following figures and more particularly of Figures 3 to 7.

Les figures 3 et 4 représentent schématiquement, vue en coupe et de dessus les moyens 10 et 11 destinés respectivement à assurer le déplacement du cylindre d'accrochage 4 portant les billes 5 et celui des coins de calage 12. Ces moyens sont représentés sur ces figures dans la configuration correspondant à l'état dit de repos, c'est-à-dire celui qui correspond au stockage des bombes avant accrochage en vue de l'emport. La bombe porteuse 1 sur laquelle sera accrochée une première bombe portée 2 est équipée d'un dispositif conforme à l'invention. Outre la partie mâle 3 avec son cylindre d'accrochage 4 et ses billes 5, coopèrent un coulisseau dit coulisseau supérieur référencé 21 sur lequel peut venir agir la clé introduite dans le logement 90 et une glissière référencée 22 reliée solidairement au cylindre d'accrochage 4 et l'entraînant en rotation. Un doigt 23 coordonne les mouvements du coulisseau supérieur 21 et de la glissière 22 et est solidaire d'un deuxième coulisseau dit coulisseau inférieur référencé 24 attaché à l'enveloppe 25 au moyen de plots 26 et 260 permettant son coulissement entre l'enveloppe et la tête de ces plots. Ce coulisseau 24 comporte une lumière 27 qui permet le coulissement du coulisseau 24 au niveau du plot central 260 (Figure 3) tout le long de la lumière 27. Ce coulisseau 24 est égaliement rendu solidaire des deux coins de calage 12 qui suivront son déplacement mais qui sont rappelés dans la position initiale dite de repos au moyen d'un ressort de rappel 29. Dans l'exemple décrit, le dispositif conforme à l'invention fait partie intégrante de la bombe c'est-à-dire que l'enveloppe 25 est confondue avec la virole (ou corps) de la bombe,mais comme cela a déjà été dit, un tel dispositif peut être réalisé sous la forme d'une pièce indépendante. Le coulisseau 21 et la glissière 22 présentent chacun un chemin de guidage 31 et 32 pour le doigt 23. Ils ont le même profil qui à l'état de repos ne se superpose cependant pas. Ainsi, le doigt 23 affleure dans le chemin de guidage 31 du coulisseau 21. Le profil, de ce chemin de guidage 31 vue en plan n'est pas représenté mais il est le même que le profil du chemin de guidage 32 du second coulisseau qui est représenté sur la figure 4. Cette figure 4, a été représentée, vue de dessus, dans une configuration où le coulisseau supérieur 21, a été enlevé, ceci pour faciliter la description et la compréhension. De plus, la glissière 22 comporte un second chemin de guidage longitudinal 33. Enfin, le coulisseau 21 et la glissière 22 sont maintenus l'un à l'autre par des pattes 330 permettant le mouvement relatif dans deux plans parallèles de l'une et de l'autre de ces pièces 21 et 22.Figures 3 and 4 schematically show, in section and from above the means 10 and 11 respectively intended to ensure the movement of the attachment cylinder 4 carrying the balls 5 and that of the wedging wedges 12. These means are shown in these figures in the configuration corresponding to the so-called rest state, that is to say that which corresponds to the storage of the bombs before hanging for the purpose of carrying. The carrier bomb 1 on which will be attached a first bomb 2 carried is equipped with a device according to the invention. In addition to the male part 3 with its latching cylinder 4 and its balls 5, cooperate a slide called upper slide referenced 21 on which the key inserted in the housing 90 can act and a slide referenced 22 connected integrally to the latching cylinder 4 and driving it in rotation. A finger 23 coordinates the movements of the upper slide 21 and of the slide 22 and is integral with a second slide called the lower slide referenced 24 attached to the casing 25 by means of studs 26 and 260 allowing its sliding between the casing and the head of these studs. This slider 24 has a light 27 which allows the slider 24 to slide at the level of the central stud 260 (Figure 3) all along the light 27. This slider 24 is also made integral with the two wedging wedges 12 which will follow its movement but which are returned to the initial so-called rest position by means of a return spring 29. In the example described, the device according to the invention is an integral part of the bomb, that is to say that the envelope 25 is confused with the shell (or body) of the bomb, but as has already been said, such a device can be produced in the form of an independent part. The slide 21 and the slide 22 each have a guide path 31 and 32 for the finger 23. They have the same profile which in the state of rest, however, does not overlap. Thus, the finger 23 is flush with the guide path 31 of the slide 21. The profile of this guide path 31 in plan view is not shown but it is the same as the profile of the guide path 32 of the second slide which is shown in Figure 4. This Figure 4 has been shown, seen from above, in a configuration where the upper slide 21 has been removed, this to facilitate description and understanding. In addition, the slide 22 has a second longitudinal guide path 33. Finally, the slide 21 and the slide 22 are held together by lugs 330 allowing relative movement in two parallel planes of one and on the other of these parts 21 and 22.

L'accrochage de la première bombe porteuse 1 avec la seconde bombe portée 2 est réalisé notamment grâce à la coopération de ce coulisseau et cette glissière dont le mouvement est assuré par le doigt 23 comme cela est maintenant décrit et illustré au moyen des figures 5 et 6.The attachment of the first carrier bomb 1 with the second bomb bomb 2 is produced in particular thanks to the cooperation of this slide and this slide whose movement is ensured by the finger 23 as is now described and illustrated by means of FIGS. 5 and 6.

La figure 5, représente, vue en coupe , la position des différents éléments constituant le système d'accrochage et de calage proprement dit, à savoir le coulisseau et la glissière 21 et 22, le doigt 23 guidé par les chemins de guidage 31, 32, 33. Les ressorts 29 et les coins de calage 12, ces éléments étant entraînés en mouvement au moyen de la clé 102, lorsque la clé est dans une position telle que le doigt 23 est déverrouillé. La figure 6 est une vue en plan de ce même système d'accrochage et de calage dans une configuration intermédiaire suivant la configuration de déverrouillage et précédant le verrouillage, représentée sur la figure précédente, durant laquelle le doigt 23 guidé dans les chemins de guidage courbes 31 et 32 alors mis en coïncidence, entraîne en rotation la glissière 22 et le cylindre 4 qui lui est solidaire.Figure 5 shows, in sectional view, the position of the various elements constituting the attachment and wedging system itself, namely the slide and the slide 21 and 22, the finger 23 guided by the guide tracks 31, 32 , 33. The springs 29 and the wedging wedges 12, these elements being driven in movement by means of the key 102, when the key is in a position such that the finger 23 is unlocked. Figure 6 is a plan view of the same attachment and wedging system in an intermediate configuration according to the unlocking configuration and before locking, shown in the previous figure, during which the finger 23 guided in the curved guide paths 31 and 32 then placed in coincidence, rotates the slide 22 and the cylinder 4 which is integral with it.

Pour cela la clé 100 qui comprend un levier de commande 101 et un pêne 102 capable d'appliquer un effort sur le coulisseau supérieur 21 sur une partie recourbée de celui-ci appelé, gache 103 par analogie avec le pêne 102. Au fur et à mesure que l'opérateur appuie le pêne 102 de la clé 100 sur la gache 103 du coulisseau supérieur 21 dans le sens de la flèche 104 (figure 5), le jeu de coulisseaux supérieur et inférieur 21 et 24 se déplace dans le sens de la flèche 105. Le doigt 23 d'abord guidé par le chemin de guidage longitudinal 33 entraînant le coulisseau inférieur 24 jusqu'à ce que le chemin de guidage 32 coïncide avec le chemin de guidage 31 du coulisseau supérieur 21, chemins dont les profils sont l'un et l'autre identiques et courbes comme cela a été dit précédemment. Dès cet instant, il devient possible à l'opérateur de faire tourner, en agissant sur le bras de commande 101 de la clé 100, l'ensemble du coulisseau supérieur et de la glissière 21 et 22 de façon à faire tourner le cylindre 4 jusqu'à ce que les billes 5 se présentent face aux alvéoles 9 de la cavité 7 de la seconde bombe 2 qui doit être portée et accrochée à la première bombe porteuse 1 en vue de l'encliquetage des billes sur le rebord 8 de cette cavité, assurant ainsi l'accrochage recherché. La figure 6 représente schématiquement une configuration intermédiaire montrant bien l'angle oC existant déjà entre l'axe longitudinal AB du dispositif et l'axe A'B' longitudinal du système de coulisseau supérieur et glissière. Simultanément, le doigt 23 a entraîné le coulisseau inférieur 24 dans un déplacement longitudinal dans le sens de la flèche 105 comprimant les ressorts de rappel 29 et déplaçant les coins de calage 12 vers le cylindre d'accrochage 5. Suivant la flèche 106 (Figure 5), ces coins de calage se trouvent alors dans une position autorisant la mise en place à leur niveau de la surface oblique de l'appui fixe 13 dit à contact oblique. Lorsque l'opérateur procède à la dernière étape, à savoir celle du verrouillage de la seconde à la première bombe, en agissant sur la clé dans le sens inverse de celui qui vient d'être décrit, chaque élément retrouve la position qu'il occupait à l'état antérieur dit de repos décrit précédemment. Notamment les coins de calage reculant viennent s'appliquer sur l'appui 13, assurant ainsi le calage de la bombe portée maintenue par ailleurs à la fois par le système d'accrochage et l'appui fixe à contact courbe 15. Elle est immobilisée dans toutes les directions sans qu'il soit nécessaire d'avoir recours à des réglage de calage plus ou moins sophistiqués.For this, the key 100 which includes a control lever 101 and a bolt 102 capable of applying a force on the upper slide 21 on a curved part of the latter called, striker 103 by analogy with the bolt 102. As and as the operator presses the bolt 102 of the key 100 on the keeper 103 of the upper slide 21 in the direction of the arrow 104 (FIG. 5), the set of upper and lower slides 21 and 24 moves in the direction of the arrow 105. The finger 23 first guided by the longitudinal guide path 33 driving the lower slide 24 until the guide path 32 coincides with the guide path 31 of the upper slide 21, paths whose profiles are l both identical and curved as mentioned above. From this moment, it becomes possible for the operator to rotate, by acting on the control arm 101 of the key 100, the assembly of the upper slide and the slide 21 and 22 so as to rotate the cylinder 4 up to '' that the balls 5 are facing the cells 9 of the cavity 7 of the second bomb 2 which must be worn and attached to the first carrier bomb 1 in order to snap the balls onto the rim 8 of this cavity, thus ensuring the desired attachment. FIG. 6 schematically represents an intermediate configuration clearly showing the angle oC already existing between the longitudinal axis AB of the device and the longitudinal axis A'B 'of the upper slide and slide system. Simultaneously, the finger 23 has driven the lower slide 24 in a longitudinal movement in the direction of the arrow 105 compressing the return springs 29 and moving the wedges 12 towards the latching cylinder 5. According to arrow 106 (Figure 5 ), these wedging wedges are then in a position allowing the positioning at their level of the oblique surface of the fixed support 13 said oblique contact. When the operator proceeds to the last step, namely that of locking the second to the first bomb, by acting on the key in the opposite direction to that just described, each element returns to the position it occupied in the prior state known as rest described above. In particular, the receding wedging wedges are applied to the support 13, thus ensuring the wedging of the carried bomb maintained, moreover, both by the attachment system and the fixed support with curved contact 15. It is immobilized in all directions without the need for more or less sophisticated timing adjustments.

La clé 100 et le logement 90 dans lequel l'opérateur l'introduit pour assurer l'accrochage ou le décrochage de deux bombes, comme. cela vient d'être décrit, coopérent entre eux de telle sorte que cette clé puisse être sortie de ce logement uniquement lorsque le verrouillage est effectif, soit que le dispositif soit à l'état dit de repos lors du stockage ou ait retrouvé ce même état après l'opération d'accrochage de la bombe portée. Les figures 7a et 7b, illustrent cette combinaison assurant la vérification du verrouillage.The key 100 and the housing 90 in which the operator inserts it to ensure the attachment or detachment of two bombs, such as. this has just been described, cooperate with each other so that this key can be removed from this housing only when the locking is effective, either that the device is in the so-called rest state during storage or has found this same state after the attachment of the carried bomb. Figures 7a and 7b illustrate this combination ensuring the verification of the locking.

Dans la figure 7a, le coulisseau supérieur et la glissière occupent une position correspondant à la configuration représentée sur la figure 1. La clé 100 est introduite dans le logement 90 prévu à cet effet. Le coulisseau supérieur 21 et plus particulièrement la gache 103 de ce coulisseau sur lequel doit venir appuyer le pêne 102 de la clé 100 est prolongé par un bec 110 Dans la position de repos (Figure 7a), la clé peut être introduite ou retirée sans difficulté, le logement 90 n'étant pas occulté par ce bec 110. En revanche, comme cela est illustré sur la figure 7b, quand la clé a accomplit sa fonction, c'est-à-dire lorsqu'elle a amené le coulisseau et la glissière 21 et 22 dans la position notamment représentée sur les figures 6 et 7b, l'opérateur ne peut en aucun cas enlever la clé : en effet, le logement 90 est partiellement occulté par le bec 110. Donc il doit, ou poursuivre la manoeuvre ou revenir en arrière. Il est dans ces conditions facile de surveiller le bon verrouillage de toutes les bombes accrochées les unes aux autres au moyen du dispositif conforme à l'invention. Il suffit de constater qu'aucune clé ne subsiste après montage et s'il en subsistait une ouvliée par erreur, de vérifier qu'il est possible de l'enlever et donc d'accomplir cette action.In FIG. 7a, the upper slide and the slide occupy a position corresponding to the configuration shown in FIG. 1. The key 100 is inserted into the housing 90 provided for this purpose. The upper slide 21 and more particularly the keeper 103 of this slide on which the bolt 102 of the key 100 must come to bear is extended by a spout 110 In the rest position (Figure 7a), the key can be inserted or removed without difficulty, the housing 90 not being obscured by this beak 110. On the other hand, as illustrated in FIG. 7b, when the key has accomplished its function, that is to say when it has brought the slide and the slide 21 and 22 into the position in particular shown in Figures 6 and 7b, the operator can in no case remove the key: in fact, the housing 90 is partially obscured by the spout 110. So he must, or continue the maneuver or go back. Under these conditions, it is easy to monitor the correct locking of all the bombs attached to each other by means of the device according to the invention. It suffices to note that no key remains after assembly and if there was one left in error, to verify that it is possible to remove it and therefore to perform this action.

La fonction d'accrochage de verrouillage et de calage vient d'être décrite, mais selon une autre caractéristique de l'invention, un tel dispositif comporte également un élément de liaison (référence 70 sur la Figure 1) entre le cylindre 4 porte bille et la cavité 7, élément contenant les organes de transfert électrique d'une part et les moyens d'éjection d'autre part.The locking and wedging hooking function has just been described, but according to another characteristic of the invention, such a device also comprises a connecting element (reference 70 in FIG. 1) between the cylinder 4 with ball bearing and the cavity 7, an element containing the electrical transfer members on the one hand and the ejection means on the other hand.

La figure 8 illustre schématiquement un exemple de réalisation d'un tel élément de liaison 70. Les deux charges (dans l'exemple décrivant la bombe 1 porteuse et la bombe 2 portée), sont représentées. La surface de séparation au niveau du cylindre 4 porte-billes de la bombe 2 portée, est symbolisée par le trait pointillé 78. Dans un premier temps, on décrit d'abord le système du transfert des ordres électriques. Toute partie femelle 6 référencée 6a dans le cas de la bombe 1 et 6b dans le cas de la bombe 2 comporte une pluralité de plots mobiles 82a et 82b. Dans l'exemple décrit, ils sont au nombre de quatre répartis uniformément sur une couronne 85a et 85b dont deux sont seulement visibles sur la figure 9. Des plots de contact fixes 83b (les plots fixes appartenant à la bombe 1 n'apparaissent pas sur la figure 8) en un même nombre que les plots de contact mobile 82a sont prévus et répartis de la même manière sur une couronne appartenant au cylindre 4 porte-billes. L'agencement de ces plots mobiles et de ces plots fixes sont tels qu'ils coopèrent entre eux pour assurer, lorsqu'ils se trouvent appliqués respectivement les uns contre les autres, un bon contact électrique. Sur la figure 8, la couronne 85a appartient à la cavité 6a de la bombe porteuse 1 et les plots mobiles 82a (symbolisé par la présence des ressorts 850 viennent en appui sur les contacts fixes 83b du cylindre porte-billes 5 de la bombe portée 2. A l'extrémité inférieure de l'élément de liaison 70 sont également représentés les plots mobiles 82b portés par la couronne 85b appartenant à la cavité 6b de la bombe portée 2. L'organe de liaison 70 comporte également un séquenceur 159 qui reçoit les ordres électriques émis par le pilote de l'aéronef et aboutissant à l'adaptateur accroché au pylone de cet aéronef. Les ordres transitent de la façon suivante, illustrée schématiquement au moyen des figures 9a et 9b.FIG. 8 schematically illustrates an exemplary embodiment of such a connecting element 70. The two charges (in the example describing the bomb 1 carrier and the bomb 2 carried), are shown. The separation surface at the level of the cylinder 4 ball-carrier of the bomb 2 carried, is symbolized by the dotted line 78. Firstly, the system for the transfer of electrical orders is first described. Any female part 6 referenced 6a in the case of the bomb 1 and 6b in the case of the bomb 2 comprises a plurality of movable studs 82a and 82b. In the example described, there are four of them distributed uniformly over a ring 85a and 85b, two of which are only visible in FIG. 9. Fixed contact pads 83b (the fixed pads belonging to the bomb 1 only appear not appear in Figure 8) in the same number as the movable contact pads 82a are provided and distributed in the same way on a ring belonging to the cylinder 4 ball holder. The arrangement of these movable pads and these fixed pads are such that they cooperate with each other to ensure, when they are applied respectively against each other, good electrical contact. In FIG. 8, the crown 85a belongs to the cavity 6a of the carrier bomb 1 and the movable studs 82a (symbolized by the presence of the springs 850 come to bear on the fixed contacts 83b of the ball-bearing cylinder 5 of the bomb carried 2 At the lower end of the connecting element 70 are also represented the movable studs 82b carried by the crown 85b belonging to the cavity 6b of the bomb being carried 2. The connecting member 70 also includes a sequencer 159 which receives the electrical orders emitted by the pilot of the aircraft and leading to the adapter attached to the pylon of this aircraft The orders pass as follows, illustrated diagrammatically by means of FIGS. 9a and 9b.

Dans la figure 9a deux bombes sont accrochées l'une à l'autre, l'une porteuse 1 (de rang n - 1) se trouvant à la position supérieure, l'autre portée 2 de rang (n) se trouvant à la position inférieure (ce nombre de deux n'est donné qu'à titre d'exemple). Dans la figure 9b une seule bombe reste accrochée à l'adaptateur du véhicule porteur (non représenté). Le signal S est appliqué sur le premier plot de contact mobile 150, dans le cas de la figure 9a, il suit le chemin conducteur constitué par le ressort 151, la pointe 152 s'appliquant sur le contact fixe 153, le second ressort 154, la pointe 155 s'appliquant sur le second contact fixe 156 relié au séquenceur 159 par le ressort 161, le contact 158 est fermé par opposition au contact 160 qui est ouvert. Le séquenceur 157 est hors circuit et ne reçoit donc, dans cette séquence, aucune impulsion. Il en résulte que seul le séquenceur 159 va être activé et pouvoir délivrer les signaux de commande assurant le bon déroulement de la suite des opérations programmées. Dans le cas où une seule bombe est encore accrochée, le contact 160 est au contraire en position fermée et ce signal est donc appliqué au séquenceur 157 qui peut ainsi jouer son rôle. Dans l'exemple décrit comme cela a été dit précédemment les plots fixes et mobiles sont au nombre de quatre. Trois de ces plots sont utilisés pour commander les séquenceurs et le quatrième pour déclencher une charge pyrotechnique 170 telle que représentées sur la figure 8. Le circuit de transfert électrique destiné à commander la mise à feu de cette charge pyrotechnique 170 suit le même processus que celui qui vient d'être décrit pour les différents séquenceurs : à savoir que, seule la charge pyrotechnique de la bombe la plus inférieure (bombe de rang n) est mise à feu ; la bombe de rang (n - 1) ne pouvant quant à elle être mise à feu seulement lorsque la bombe de rang (n) a été elle-même éjectée. La mise à feu d'une charge pyrotechnique, par exemple la charge 170 de la figure 8 provoque le mouvement d'un piston 171 qui accomplit alors deux fonctions, la première consistant à fermer un interrupteur 190 permettant au séquenceur de délivrer les différents ordres de commande initialement programmés, la seconde de libérer les billes 5 lorsque l'empreinte en creux 193 du piston vient s'encastrer dans l'empreinte en relief 194 de la partie femelle de la bombe 1 supérieure. Les billes étant escamotées ne soutiennent plus la bombe portée la plus éloignée de l'aéronef qui se trouve alors éjectée avec une vitesse dépendant de la charge pyrotechnique mise en jeu.In Figure 9a two bombs are attached to each other, one carrier 1 (of rank n - 1) being in the upper position, the other carried 2 of rank (n) being in the position lower (this number of two is given only as an example). In FIG. 9b, a single bomb remains attached to the adapter of the carrier vehicle (not shown). The signal S is applied to the first movable contact pad 150, in the case of FIG. 9a, it follows the conductive path formed by the spring 151, the tip 152 applying to the fixed contact 153, the second spring 154, the tip 155 being applied to the second fixed contact 156 connected to the sequencer 159 by the spring 161, the contact 158 is closed as opposed to the contact 160 which is open. The sequencer 157 is off and therefore receives no pulse in this sequence. As a result, only the sequencer 159 will be activated and able to deliver the control signals ensuring the smooth running of the rest of the programmed operations. In the case where only one bomb is still attached, the contact 160 is on the contrary in the closed position and this signal is therefore applied to sequencer 157 which can thus play its role. In the example described as mentioned above, there are four fixed and movable studs. Three of these pads are used to control the sequencers and the fourth to trigger a pyrotechnic charge 170 as shown in FIG. 8. The electrical transfer circuit intended to control the firing of this pyrotechnic charge 170 follows the same process as that which has just been described for the various sequencers: namely that only the pyrotechnic charge of the lowest bomb (bomb of rank n) is ignited; the bomb of rank (n - 1) being able to be ignited only when the bomb of rank (n) was itself ejected. The firing of a pyrotechnic charge, for example the charge 170 of FIG. 8 causes the movement of a piston 171 which then performs two functions, the first consisting in closing a switch 190 allowing the sequencer to issue the different orders of command initially programmed, the second to release the balls 5 when the hollow imprint 193 of the piston is embedded in the imprint in relief 194 of the female part of the upper bomb 1. The balls being retracted no longer support the bomb carried farthest from the aircraft which is then ejected with a speed depending on the pyrotechnic charge involved.

Toutes les charges ainsi accrochées, se trouvent successivement éjectées l'une après l'autre, la charge inférieure de rang (n) l'étant toujours avant celle de rang (n - 1) laquelle l'est avant celle de rang (n - 2) et ainsi de suite.All the charges thus attached, are successively ejected one after the other, the lower charge of rank (n) always being before that of rank (n - 1) which is before that of rank (n - 2) and so on.

L'invention s'applique notamment aux systèmes d'armes nécessitant le largage successif d'un grand nombre de charges militaires telles que des bombes ou projectiles divers.The invention applies in particular to weapons systems requiring the successive dropping of a large number of military charges such as bombs or various projectiles.
