Description

Les bouées d'écoute sont constituées généralement d'une charge dans laquelle sont disposés les circuits et appareils destinés à la réception et/ou à l'émission de signaux et d'un conteneur dans lequel sont logés les organes tels qu'antenne repliée, parachute de freinage, etc... L'ensemble constitué par la charge et le conteneur est largué à partir d'un aéronef tel qu'un avion, des moyens étant prévus pour désolidariser le conteneur de la charge, afin de permettre le déploiement du parachute, notamment. Outre ces moyens, l'ensemble ainsi défini comprend également des moyens qui verrouillent ou solidarisent le conteneur et la charge pendant toute la période de stockage de manutention ou de non-utilisation, ces moyens de verrouillage ne devant être déverrouillés qu'au moment du largage, ou immédiatement après le largage.The listening buoys generally consist of a load in which are arranged the circuits and apparatuses intended for the reception and / or the emission of signals and of a container in which are housed the members such as folded antenna, braking parachute, etc ... The assembly constituted by the load and the container is released from an aircraft such as an airplane, means being provided to separate the container from the load, in order to allow the deployment of the parachute, in particular. In addition to these means, the assembly thus defined also comprises means which lock or secure the container and the load during the entire storage period of handling or non-use, these locking means only having to be unlocked at the time of the release. , or immediately after dropping.

Tous les dispositifs de séparation ou d'éjection du conteneur de la-charge connus sont plus ou moins complexes, et donc relativement difficiles à fabriquer et à mettre en oeuvre.All known devices for separating or ejecting the container from the load are more or less complex, and therefore relatively difficult to manufacture and to implement.

La présente invention a pour but de proposer un'dispositif d'éjection qui soit simple à réaliser, sur dans son fonctionnement et qui permette toutes les manipulations pendant toute la période de stockage.The object of the present invention is to propose an ejection device which is simple to produce, safe in its operation and which allows all manipulations during the entire storage period.

La présente invention a pour objet un dispositif d'éjection automatique du conteneur d'une charge telle qu'une bouée d'écoute, caractérisé en ce qu'il comprend un support de conteneur solidaire de la, charge et au moins deux languettes souples ayant chacune une extrémité reliée au conteneur tandis que lautre extrémité est reliée à un organe élastique disposé dans le creux d'une nervure annulaire extérieure ménagée dans le support de charge.The present invention relates to an automatic device for ejecting a container from a load such as a sheet buoy, characterized in that it comprises a container support secured to the load and at least two flexible tabs having each one end connected to the container while the other end is connected to an elastic member disposed in the hollow of an outer annular rib formed in the load support.

D'autres avantages et caractéristiques apparaîtront à la lecture de la description donnée ci-dessous à titre indicatif mais non limitatif d'un mode de réalisation de l'invention et du dessin annexé sur lequel :

  • La figure 1 est une vue partiellement en coupe et en élévation d'un mode de réalisation du dispositif selon l'invention.
  • La figure 2 est une vue partiellement en coupe et en élévation conforme à la figure 1, l'organe élastique étant hors de son logement.
  • La figure 3 est une vue partielle en élévation des demi-coquilles déployées et le tube hors du support.
Other advantages and characteristics will appear on reading the description given below by way of indication but not limiting of an embodiment of the invention and of the appended drawing in which:
  • Figure 1 is a partially sectional and elevational view of an embodiment of the device according to the invention.
  • Figure 2 is a view partially in section and in elevation according to Figure 1, the elastic member being out of its housing.
  • Figure 3 is a partial elevational view of the deployed half-shells and the tube out of the support.

Le dispositif de largage d'une charge conforme à l'invention, comprend un support 1 qui présente la forme d'une coupelle 2 et qui peut être réalisé, soit directement à partir du corps de la charge 3, soit rapporté sur le corps de la charge, mais rendu solidaire de ce dernier par tout moyen approprié.The load release device according to the invention comprises a support 1 which has the shape of a cup 2 and which can be produced either directly from the body of the load 3, or attached to the body of the charge, but made solidary of the latter by any appropriate means.

Un tube 4 constitué en une ou plusieurs parties reliées ou non entre elles assure la fonction de conteneur pour les divers éléments associés à la charge, tels que parachute, antenne, etc... Le tube 4 est logé par sa base ouverte dans le support 1, les dimensions internes de la coupelle 2 et externes du tube 4 sont choisies de façon qu'il n'y ait pas de jeu entre eux.A tube 4 made up of one or more parts connected or not connected together ensures the function of container for the various elements associated with the load, such as a parachute, antenna, etc. The tube 4 is housed by its open base in the support 1, the internal dimensions of the cup 2 and the external dimensions of the tube 4 are chosen so that there is no play between them.

A l'extrémité supérieure du tube 4 sont articulées sur des axes 5, au moins deux demi-coquilles 6 constituant, à l'état replié, un cylindre dont les dimensions internes sont supérieures aux dimensions externes du support 1. De plus, la surface latérale de chaque demi-coquille 6 est supérieure à la moitié de la surface latérale du tube 4. De ce fait, toute la surface latérale du tube 4 est recouverte par les demi-coquilles 6 qui se chevauchent légèrement l'une sur l'autre.At the upper end of the tube 4 are articulated on axes 5, at least two half-shells 6 constituting, in the folded state, a cylinder whose internal dimensions are greater than the external dimensions of the support 1. In addition, the surface lateral of each half-shell 6 is greater than half of the lateral surface of the tube 4. Therefore, the entire lateral surface of the tube 4 is covered by the half-shells 6 which slightly overlap one on the other .

Sur les demi-coquilles 6 est attachée une extrémité de languettes 7, le point de fixation de ces languettes pouvant être un point quelconque de la partie supérieure de la surface latérale desdites demi-coquilles. Les languettes 7 au nombre de deux par exemple, se présentent sous la forme de bandes rectangulaires de longueur égale approximativement à la hauteur des demi-coquilles 7 ou du tube 4 et dont la largeur et l'épaisseur sont respectivement de l'ordre de 50 mm et 0,15 mm.On the half-shells 6 is attached one end of the tongues 7, the point of attachment of these tongues possibly being any point on the upper part of the lateral surface of the said half-shells. The tongues 7, two in number for example, are in the form of rectangular strips of length approximately equal to the height of the half-shells 7 or of the tube 4 and whose width and thickness are respectively of the order of 50 mm and 0.15 mm.

L'autre extrémité de chaque languette 7 est conformée de manière à permettre le logement et le maintien d'un organe élastique 8 se présentant sous la forme d'un bourrelet et destiné à être placé dans le creux 9 d'une nervure annulaire extérieure 10 ménagée dans les-demi-coquilles 6, la conformation du logement 11 de l'organe élastique 8 étant telle que ce dernier ne puisse trop se déplacer dans ledit logement 11, aussi bien dans l'état de stockage qu'en fonctionnement.The other end of each tongue 7 is shaped so as to allow the housing and the maintenance of an elastic member 8 in the form of a bead and intended to be placed in the hollow 9 of an outer annular rib 10 formed in the half-shells 6, the conformation of the housing 11 of the elastic member 8 being such that the latter cannot move too much in said housing 11, both in the storage state and in operation.

La nervure 10 s'ajuste parfaitement dans le creux d'une nervure correspondante 12 ménagée à la périphérie du support 1.The rib 10 fits perfectly in the hollow of a corresponding rib 12 formed at the periphery of the support 1.

Par ailleurs, le support 1 comprend une rainure annulaire sous forme de gorge 13 dans laquelle vient se loger un téton de centrage et de blocage 14 prévu sur chacune des demi-coquilles 6.Furthermore, the support 1 comprises an annular groove in the form of a groove 13 in which is housed a centering and locking stud 14 provided on each of the half-shells 6.

Au cours de stockage de la charge, l'ensemble se trouve tel que représenté sur la figure 1, les tétons 14 et le boudin élastique 8 constituant l'organe élastique assurent le maintien du conteneur sur le support 1, tandis que les languettes 7 sont plaquées contre les demi-coquilles. Si besoin est, on peut les maintenir dans cet état en roulant autour des languettes, et par conséquent autour des demi-coquilles une bande adhésive quelconque qu'on arrache, par exemple, lors de l'embarquement dans le moyen de transport à partir duquel la charge doit être larguée.During storage of the load, the assembly is as shown in Figure 1, the pins 14 and the elastic flange 8 constituting the elastic member maintain the container on the support 1, while the tongues 7 are pressed against the half-shells. If necessary, they can be kept in this state by rolling around the tabs, and therefore around the half-shells, any adhesive tape that is torn off, for example, when boarding the means of transport from which the load must be released.

Lorsqu'on largue la charge à partir d'un avion ou tout autre moyen de transport aérien, le vent s'engouffre entre les demi-ccnquilles 6 et les languettes 7 qui présentent unet-trainée suffisante pour extraire le bourrelet 8 hors du logement 9; la traînée est déterminée par la nature du matériau utilisé pour la confection desdites languettes et par leurs dimensions. Dans uncexemple de réalisation, les languettes sont obtenues à partir de feuilles souples d'aluminium et présentent les dimensions rappelées ci-dessus.When dropped the load from an aircraft or any other airborne transportation means, the wind blows between the half-ccnquilles 6 and the tabs 7 which have a sufficient drag t to extract the bead 8 from the housing 9; the drag is determined by the nature of the material used for making said tongues and by their dimensions. In an exemplary embodiment, the tongues are obtained from flexible aluminum sheets and have the dimensions recalled above.

Dès que le bourrelet 8 est extrait de son logement 9, il glisse le long des demi-coquilles 6 pendant que les languettes se gonflent, permettant ainsi aux demi-coquilles 6 de se déployer autour des axes 5 d'articulation.As soon as the bead 8 is extracted from its housing 9, it slides along the half-shells 6 while the tongues swell, thus allowing the half-shells 6 to deploy around the axes 5 of articulation.

A l'état complètement déployé des demi-coquilles, le conteneur ou tube 4 est sollicité vers la désolidarisation d'avec le support 1 sous l'action de la pression exercée sur les faces internes desdites demi-coquilles. Lorsque le conteneur 4 est séparé du support 1, les organes qu'il contenait sont libérés et peuvent remplir leurs fonctions propres.In the fully deployed state of the half-shells, the container or tube 4 is urged towards detachment from the support 1 under the action of the pressure exerted on the internal faces of said half-shells. When the container 4 is separated from the support 1, the organs which it contained are released and can fulfill their own functions.

Bien entendu, l'invention n'est pas limitée au mode de réalisation décrit ci-dessus, mais en couvre au contraire toutes les variantes. C'est ainsi que le conteneur et les demi-coquilles pourraient être remplacés par un tube en deux parties articulées l'une à l'autre librement, notamment au moyen d'un rebord s'engageant dans une fente appropriées de façon que lorsque le bourrelet et les languettes souples remplissent leurs fonctions, les demi-parties du conteneur soient sollicitées vers le détachement l'une de l'autre, afin de permettre l'extraction des organes contenus dans le conteneur.Of course, the invention is not limited to the embodiment described above, but on the contrary covers all its variants. Thus the container and the half-shells could be replaced by a tube in two parts hinged to each other freely, in particular by means of a flange engaging in a suitable slot so that when the bead and the flexible tabs fulfill their functions, the half-parts of the container are urged towards detachment from one another, in order to allow the extraction of the organs contained in the container.
