Différentes propositions ont déjà été formulées pour tenter de répondre à cette demande.Various proposals have already been made to try to respond to this request.

Cependant à la connaissance de la Demanderesse, jusqu'à ce jour, aucune solution n'a donné totalement satisfaction sur le plan de la fiabilité, simplicité de mise en oeuvre et coût.However, to the knowledge of the Applicant, to date, no solution was entirely satisfactory in terms of reliability, simplicity of implementation and cost.

La présente invention vient améliorer la situation grâce à un système comprenant :

  • un moyen de lancement d'une charge,
  • un fil enroulé en bobine, fixé par une première extrémité sur un corps lié au moyen de lancement et par une seconde extrémité sur la charge, et

Selon une autre caractéristique avantageuse de l'invention le dispositif de freinage est associé à un tronçon limité du fil.According to another advantageous characteristic of the invention the braking device is associated with a limited section of the wire.

Selon une autre caractéristique avantageuse de l'invention le dispositif de freinage est du type à friction.According to another advantageous characteristic of the invention the braking device is of the friction type.

Selon une autre caractéristique avantageuse de l'invention le dispositif de freinage est composé d'une structure rigide, par exemple du type annulaire, pourvue d'une série de perforations traversantes dans lesquelles le fil est engagé, par exemple en spirale, en boucle, en sinusoïde, ou encore sous toute autre configuration adéquate.According to another advantageous characteristic of the invention the braking device is composed of a rigid structure, for example annular type, provided with a series of through perforations in which the thread is engaged, for example in a spiral, in a loop, in sinusoid, or in any other suitable configuration.

D'autres caractéristiques, buts et avantages de la présente invention apparaítront à la lecture de la description détaillée qui va suivre et en regard des dessins annexés donnés à titre d'exemples non limitatifs et sur lesquels :

  • la figure 1 représente une vue schématique en coupe axiale longitudinale d'un dispositif conforme à la présente invention,
  • la figure 2 représente une vue à échelle agrandie d'un dispositif de freinage conforme à une variante de réalisation de la présente invention, et
  • la figure 3 représente une vue partielle en coupe transversale de ce dispositif de freinage, selon le plan de coupe référencé III-III sur la figure 2.
Other characteristics, aims and advantages of the present invention will appear on reading the detailed description which follows and with reference to the appended drawings given by way of nonlimiting examples and in which:
  • FIG. 1 represents a schematic view in longitudinal axial section of a device according to the present invention,
  • FIG. 2 shows an enlarged view of a braking device according to an alternative embodiment of the present invention, and
  • FIG. 3 represents a partial view in cross section of this braking device, according to the section plane referenced III-III in FIG. 2.

On aperçoit sur la figure 1 annexée un dispositif conforme à la présente invention comprenant un corps 10 formant mortier centré sur un axe O-O. Le corps 10 comporte, au niveau de son culot, une chaíne pyrotechnique 12 apte, lors de sa mise en oeuvre, à assurer le lancement ou propulsion d'une charge ou projectile 40 placée à l'extrémité opposée du corps 10.We see in Figure 1 attached a device according to the present invention comprising a mortar body 10 centered on a O-O axis. The body 10 has, at its base, a chain pyrotechnic 12 capable, during its implementation, of ensuring the launch or propulsion of a charge or projectile 40 placed at the opposite end of the body 10.

Un tel corps 10 et chaíne pyrotechnique 12, connus en soit, peuvent faire l'objet de nombreuses variantes de réalisation. Ils ne seront donc pas décrits dans le détail par la suite. De préférence la chaíne pyrotechnique 12 procède par génération de gaz sous pression.Such a body 10 and pyrotechnic chain 12, known per se, can be the subject of numerous variant embodiments. They will therefore not described in detail below. Preferably the pyrotechnic chain 12 proceeds by generation of gas under pressure.

De même la charge ou projectile 40 peut faire l'objet de nombreux modes de réalisation et ne sera donc pas décrit dans le détail par la suite.Similarly, the charge or projectile 40 can be the subject of numerous embodiments and will therefore not be described in detail below.

Comme on l'a indiqué précédemment dans le cadre de l'invention il est prévu un fil 20 dont une première extrémité 21 est fixée au corps 10, par exemple à proximité des moyens pyrotechniques 12 ou sur le culot du corps 10, tandis que la seconde extrémité opposée 22 du fil 20, est fixée sur la charge 40.As previously indicated in the context of the invention, it a wire 20 is provided, a first end 21 of which is fixed to the body 10, by example near the pyrotechnic means 12 or on the base of the body 10, while the second opposite end 22 of the wire 20, is fixed to the charge 40.

Par ailleurs dans le cadre de l'invention le fil 20 est associé à un dispositif de freinage 30.Furthermore, in the context of the invention, the wire 20 is associated with a braking device 30.

Selon le mode de réalisation particulier représenté sur les figures annexées le dispositif de freinage 30 est associé à une zone du fil 20 intermédiaire entre ses deux extrémités 21, 22.According to the particular embodiment shown in the figures appended the braking device 30 is associated with a zone of the wire 20 intermediate between its two ends 21, 22.

Les deux tronçons du fil référencés respectivement 23 et 24 disposés de part et d'autre du dispositif de freinage 30 sont chacun respectivement disposés en bobine sous forme d'hélices centrées sur l'axe longitudinal O-O du corps et référencées respectivement 25 et 26 sur la figure 1 annexée.The two sections of the wire referenced respectively 23 and 24 arranged on either side of the braking device 30 are each respectively arranged in a coil in the form of helices centered on the axis longitudinal O-O of the body and referenced respectively 25 and 26 on the Figure 1 attached.

Plus précisément encore selon le mode de réalisation particulier représenté sur les figures annexées le dispositif de freinage 30 comporte une rondelle rigide 32 de type annulaire centrée sur l'axe longitudinal O-O du corps et dont le plan moyen s'étend perpendiculairement à cet axe. La rondelle 32 comporte des orifices traversants 34 parallèles à l'axe longitudinal O-O du corps. Il peut être prévu ainsi plusieurs passages traversants 34 équi-répartis ou non sur la rondelle 32.More precisely still according to the particular embodiment shown in the accompanying figures the braking device 30 comprises a rigid washer 32 of annular type centered on the longitudinal axis O-O of the body and whose mean plane extends perpendicular to this axis. The washer 32 has through holes 34 parallel to the axis longitudinal O-O of the body. Several passages can thus be provided through 34 equi-distributed or not on the washer 32.

Bien entendu le nombre de passages 34 illustrés sur la figure annexée n'est pas limitatif.Of course the number of passages 34 illustrated in the figure attached is not limiting.

La zone intermédiaire du fil 20 est enroulée, par exemple en spirale, en boucle, en sinusoïde, ou encore sous toute autre configuration adéquate, sur la rondelle 32 en passant dans certains choisis des passages 34 comme illustré sur les figures 1 et 2.The intermediate zone of the wire 20 is wound, for example in a spiral, looped, sinusoidal, or in any other suitable configuration, on washer 32 passing through some selected passages 34 as illustrated in Figures 1 and 2.

Le nombre de passages 34 et le pas des passages 34 retenus pour recevoir le fil 20 déterminent directement l'effort de freinage par friction appliqué au fil, lors de la traction exercée sur celui-ci par le lancement de la charge 40.The number of passages 34 and the pitch of passages 34 selected for receive the wire 20 directly determine the friction braking force applied to the wire, during the traction exerted on it by the launching of the charge 40.

Ainsi le système peut aisément être adapté pour plusieurs applications en choisissant sélectivement selon l'application retenue (et notamment la masse de la charge 40 et/ou la dynamique de trajectoire souhaitée) les passages 34 requis pour obtenir l'effort de freinage attendu.Thus the system can easily be adapted for several applications by selectively choosing according to the selected application (and in particular the mass of the load 40 and / or the trajectory dynamics desired) the passages 34 required to obtain the expected braking force.

Comme on le voit sur la figure 3, de préférence la rondelle 32 est usinée pour ne pas présenter d'arête en regard du trajet de déplacement du fil 20 . Ainsi de préférence les passages 34 sont évasés au niveau de leurs entrées et respectivement sorties sur les faces de la rondelle 32 pour se raccorder sensiblement tangentiellement sur celles-ci et éviter de blesser le fil 20 lors du déplacement de celui-ci. De même la périphérie interne 33 de la rondelle 32 sur laquelle se déplace également le fil 20 est de préférence arrondie, par exemple sous forme d'une calotte torique.As seen in Figure 3, preferably the washer 32 is machined so as not to present an edge opposite the path of movement of the wire 20. Thus preferably the passages 34 are flared at their inputs and outputs respectively on the faces of the washer 32 to connect substantially tangentially to them and avoid injuring the wire 20 when moving it. Likewise the internal periphery 33 of the washer 32 on which the wire 20 also moves is preferably rounded, for example in the form of an O-ring.

Le fonctionnement du dispositif ainsi décrit est globalement le suivant.The operation of the device thus described is generally the next.

L'initiation de la charge pyrotechnique 12 provoque la mise en pression de la zone comprise entre l'enveloppe 10 et le projectile ou charge 40, provoquant son expulsion. The initiation of the pyrotechnic charge 12 causes the pressure in the area between envelope 10 and the projectile or charge 40, causing his expulsion.

Le fil 20 se délove alors librement au niveau de sa bobine 26 adjacente à la charge 40, tout en restant légèrement tendu. A cet effet par exemple la bobine 26 peut être enduite de cire ou de résine, voire de tout matériau équivalent.The wire 20 then loosens freely at its spool 26 adjacent to the load 40, while remaining slightly taut. To this end by example the coil 26 can be coated with wax or resin, or even any equivalent material.

Lorsque la bobine 26 est entièrement dévidée, la bobine 25 adjacente au culot du corps commence à de dévider à travers le frein 30.When the reel 26 is fully unwound, the reel 25 adjacent to the base of the body begins to unwind through the brake 30.

Au cours de cette phase le fil 20 se translate dans les passages 34. Les enroulements successifs du fil sur le frein 30 créent un effort de traction maítrisant la dynamique d'arrêt du projectile.During this phase, the wire 20 translates into the passages 34. The successive windings of the wire on the brake 30 create a tensile force controlling the dynamics of stopping the projectile.

Le projectile ou charge 40 subit ainsi, dans un premier temps, lors du délovage de la première bobine 26 une mise en vitesse rapide (effet pyrotechnique), soit un déplacement quasiment en vitesse constante dû à la mise sous tension du fil dû au délovage de la bobine 26, puis une décélération constante et soutenue due à l'action conjuguée du délovage de la bobine 25 amplifié par le frein 30.The projectile or charge 40 thus undergoes, initially, during of the unwinding of the first coil 26 rapid speeding up (effect pyrotechnic), i.e. an almost constant displacement due to the tensioning of the wire due to the unwinding of the coil 26, then a constant and sustained deceleration due to the combined action of the unwinding of the coil 25 amplified by the brake 30.

Bien entendu la présente invention n'est pas limitée au mode de réalisation ou à l'application particulière décrits et illustrés sur les figures annexées mais s'étend à toute variante conforme à son esprit.Of course, the present invention is not limited to the mode of embodiment or particular application described and illustrated in the figures annexed but extends to any variant in accordance with its spirit.

Ainsi le système peut être étendu à une disposition externe à une cartouche ou corps 10 de lanceur.Thus the system can be extended to an external arrangement to a launcher cartridge or body 10.

Par ailleurs on peut associer plusieurs fils 20 à un frein 30 et une charge unique.In addition, several wires 20 can be associated with a brake 30 and a single charge.

De la même façon on peut associer un ou plusieurs fils 20 à plusieurs freins 30 intercalés sélectivement sur la longueur du fil 20 pour gérer les dynamiques de freinage.In the same way, one or more 20 wires can be associated with several brakes 30 selectively interposed along the length of the wire 20 for manage braking dynamics.
