Dans le cas particulier des navires de guerre, il s'agit d'utiliser des dispositifs de protection pouvant être mis en oeuvre très rapidement pour protéger certains points du navire vis-à-vis d'une menace légère telle que le tir d'une roquette. Le principe d'un tel dispositif de protection est de déployer sur la trajectoire d'une menace détectée un dispositif servant d'écran et entraînant la destruction de la menace ou au moins inhibant son effet destructeur.In the particular case of warships, it is a question of using protective devices that can be implemented very quickly to protect certain points of the ship against a slight threat such as the firing of a ship. rocket. The principle of such a protection device is to deploy on the trajectory of a detected threat a screen device and resulting in the destruction of the threat or at least inhibiting its destructive effect.

Par exemple ces dispositifs de protection de l'état de l'art peuvent être des structures souples gonflables à l'aide d'un compresseur ou des bouteilles de gaz. Mais ces systèmes comportent l'inconvénient d'être d'un coût important et nécessitant une certaine logistique de maintenance pour la transmission des gaz au dispositif gonflable.
Le document US 4 262 595 A , qui est considéré comme étant l'état de la technique le plus proche de l'objet de la revendication indépendante 1, divulgue un système de protection déployable comportant une armature déployable au tour d'un tube central de l'armature, d'axe longitudinal XX', comportant deux extrémités, l'armature comportant au moins deux paires de tubes rigides.For example, these protection devices of the state of the art may be flexible structures inflatable using a compressor or gas cylinders. But these systems have the disadvantage of being a significant cost and requiring some maintenance logistics for the transmission of gases to the inflatable device.
The document US 4,262,595 A , which is considered to be the state of the art closest to the object of independent claim 1, discloses a deployable protection system comprising a frame deployable around a central tube of the armature, of axis longitudinal XX ', having two ends, the armature comprising at least two pairs of rigid tubes.

Pour pallier les inconvénients des dispositifs de protection de l'état de l'art, l'invention propose un système de protection caractérisé en ce qu'il comporte une armature dépoyable au tour d'un tube central de l'armature, d'axe longitudinal XX', comportant deux extrémités, une toile de recouvrement de l'armature, l'armature comportant :

  • au moins deux paires de tubes rigides, deux tubes rigides d'une paire, dans un respectif plan axial passant par l'axe longitudinal XX', étant articulés par une de leurs extrémités sur une respective chape solidaires, l'une, d'une des extrémités du tube central, l'autre, de l'autre extrémité dudit tube central, les autres extrémités libres des tubes rigides pouvant se déplacer dans le plan axial de la paire,

  • a semi-rigid tube pair of rigid tubes, in said axial plane of the pair, having at each of its ends a piston, each piston of a semi-rigid tube being able to slide tightly in one and in the other rigid tubes of the pair to form a pressurizing chamber in each of the rigid tubes,
the protection system further comprising a device for pressurizing the chambers of the rigid tubes to move the pistons in the rigid tubes and move the system from a folded position to a deployed position.

Avantageusement, les tubes rigides ont un degré de liberté en rotation autour d'un axe d'articulation YY' avec sa respective chape d'articulation perpendiculaire à son respectif plan axial passant par l'axe XX' du tube central.Advantageously, the rigid tubes have a degree of freedom in rotation about an axis of articulation YY 'with its respective articulation clevis perpendicular to its respective axial plane passing through the axis XX' of the central tube.

Dans une réalisation, les extrémités articulées des tubes rigides sont fermées pour former, avec le piston du tube semi-rigide, la chambre de mise en pression dans chacun des tubes rigides.In one embodiment, the articulated ends of the rigid tubes are closed to form, with the piston of the semi-rigid tube, the pressurizing chamber in each of the rigid tubes.

Dans une autre réalisation, le tube rigide comporte, du côté de son extrémité libre, une butée solidaire du tube rigide sous forme d'un joint torique entourant le tube semi-rigide.In another embodiment, the rigid tube comprises, on the side of its free end, an abutment integral with the rigid tube in the form of an O-ring surrounding the semi-rigid tube.

Dans une autre réalisation, chacun des tubes rigides comporte un guide intermédiaire pour guider une partie de l'extrémité du tube semi-rigide lors de son déplacement dans le tube rigide.In another embodiment, each of the rigid tubes comprises an intermediate guide for guiding a portion of the end of the semi-rigid tube as it moves in the rigid tube.

Dans une autre réalisation, le tube central comporte des butées d'incidence disposées sur sa périphérie de façon à ce que, le système étant en position replié, les extrémités libres des tubes rigides viennent en appui sur ces butées d'incidence pour former un angle d'incidence θ avec le tube central.In another embodiment, the central tube has thrust stops disposed on its periphery so that, the system being in the folded position, the free ends of the rigid tubes bear on these bearing stops to form an angle incidence θ with the central tube.

Dans une autre réalisation, la toile est configurée pour prendre une forme ovoïde lorsque le système est en position déployé, la toile comportant à l'une et à l'autre des extrémités du tube central une ouverture pour le passage des tubes rigides et en ce que les bords des ouvertures de la toile sont solidaires des tubes rigides pour maintenir la toile en place sur l'armature.In another embodiment, the fabric is configured to take an ovoid shape when the system is in the deployed position, the fabric comprising at one and the other ends of the central tube an opening for the passage of the rigid tubes and in that that the edges of the openings of the fabric are secured to the rigid tubes to hold the fabric in place on the frame.

La figure 1 représente une vue en coupe longitudinale du système de protection déployable selon l'invention dans une position replié dans une enveloppe de protection.The figure 1 is a longitudinal sectional view of the deployable protection system according to the invention in a folded position in a protective envelope.

Les figures 2a et 2b montrent deux vues partielles dans un sens et dans le sens opposé selon un axe longitudinal du système de la figure 1 en position déployé.The Figures 2a and 2b show two partial views in one direction and in the opposite direction along a longitudinal axis of the system of the figure 1 in the deployed position.

Le système de protection comporte essentiellement une armature 2 et une toile de recouvrement 4 configurée pour donner au système déployé la forme souhaitée au tour d'un tube central 10 de l'armature, d'axe longitudinal XX'.The protection system essentially comprises a frame 2 and a cover fabric 4 configured to give the deployed system the desired shape around a central tube 10 of the frame, of longitudinal axis XX '.

Le système est contenu dans une enveloppe de protection extérieure 6 comportant son propre dispositif d'ouverture préalable au déploiement du système de protection.The system is contained in an outer protection envelope 6 having its own opening device prior to deployment of the protection system.

Dans cet exemple de réalisation, l'enveloppe de protection 6 est de forme tubulaire selon l'axe XX'.In this embodiment, the protective envelope 6 is of tubular shape along the axis XX '.

La figure 2a montre une vue transversale à l'axe XX' selon UU' et la figure 2b une vue transversale au même axe XX' selon VV' (voir figure 1).The figure 2a shows a transverse view along the axis XX 'according to UU' and the figure 2b a transverse view on the same axis XX 'according to VV' (see figure 1 ).

L'armature du système de protection des figures 1, 2a et 2b selon l'invention comporte cinq paires P1, P2, P3, P4, P5 de tubes rigides réparties angulairement autour du tube central 10 (voir figures 2a et 2b).The armature of the protection system figures 1 , 2a and 2b according to the invention comprises five pairs P1, P2, P3, P4, P5 of rigid tubes angularly distributed around the central tube 10 (see Figures 2a and 2b ).

Chaque paire de tubes rigides, de respectifs axes longitudinaux A1A1', B1B1', C1C1', D1D1', E1E1' pour les tubes rigides 20, 24, 28, 32, 36 du côté d'une extrémité du tube central 10, soit l'extrémité gauche sur la figure 1, et A2A2', B2B2', C2C2', D1D2', E2E2' pour les tubes rigides 22, 26, 30, 34, 38 du côté de l'autre extrémité dudit tube central, soit l'extrémité droite sur la figure 1, sont dans un respectif plan axial pl1, pl2, pl3, pl4, pl5 passant par l'axe XX' du tube central.Each pair of rigid tubes, of respective longitudinal axes A 1 A 1 ', B 1 B 1 ', C 1 C 1 ', D 1 D 1 ', E 1 E 1 'for the rigid tubes 20, 24, 28, 32 , 36 on the side of one end of the central tube 10, the left end on the figure 1 , and A 2 A 2 ', B 2 B 2 ', C 2 C 2 ', D 1 D 2 ', E 2 E 2 'for the rigid tubes 22, 26, 30, 34, 38 on the other side end of said central tube, the right end on the figure 1 , are in a respective axial plane pl1, pl2, pl3, pl4, pl5 passing through the axis XX 'of the central tube.

Chacun des tubes rigides d'une paire est articulé par une de ses extrémités eA, selon un axe YY' perpendiculaire à l'axe XX', sur une chape solidaire de l'une ou de l'autre extrémité du tube central selon le tube rigide considéré, des chapes 40, 44, 48, 52, 56 d'articulation des tubes rigides 20, 24, 28, 32, 34, 36 du côté de l'extrémité gauche du tube central et des chapes 42, 46, 50, 54, 58 d'articulation des tubes rigides 22, 26, 30, 34, 38 du côté de extrémité droite du tube central 10.Each of the rigid tubes of a pair is articulated by one of its ends eA, along an axis YY 'perpendicular to the axis XX', on a clevis secured to one or the other end of the central tube according to the tube rigid considered, clevises 40, 44, 48, 52, 56 of articulation of the rigid tubes 20, 24, 28, 32, 34, 36 on the left end side of the central tube and the yokes 42, 46, 50, 54, 58 of articulation of the rigid tubes 22, 26, 30, 34, 38 of the right end side of the central tube 10.

Les tubes rigides ont un degré de liberté en rotation autour de l'axe d'articulation YY' sur la chape dans le respectif plan axial pl1, pl2, pl3, pl4, pl5 passant par l'axe XX' du tube central. Les autres extrémités libres des tubes rigides peuvent donc se déplacer dans le respectif plan axial pl1, pl2, pl3, pl4, pl5 de la paire considérée.The rigid tubes have a degree of freedom in rotation about the hinge axis YY 'on the yoke in the respective axial plane pl1, pl2, pl3, pl4, pl5 passing through the axis XX' of the central tube. The other free ends of the rigid tubes can therefore move in the respective axial plane pl1, pl2, pl3, pl4, pl5 of the pair considered.

Un tube semi-rigide 70, 71, 72, 73, 74 associé à une paire P1, P2, P3, P4, P5 de tubes rigides comporte à chacune de ses extrémités un piston 75.A semi-rigid tube 70, 71, 72, 73, 74 associated with a pair P1, P2, P3, P4, P5 of rigid tubes comprises at each of its ends a piston 75.

Les deux pistons 75 d'un tube semi-rigide ferment, de façon étanche, du côté des extrémités libres, les tubes rigides en regard d'une paire de tubes rigides à l'une et à l'autre des extrémités du tube central 10 et dans un même plan axial passant par l'axe XX'.The two pistons 75 of a semi-rigid tube sealingly close the side of the free ends, the rigid tubes facing a pair of rigid tubes at one and the other end of the central tube 10 and in the same axial plane passing through the axis XX '.

Les extrémités eA articulées des tubes rigides, du côté des chapes, sont fermées pour former avec le piston 75 dans chacun des tubes rigides, une chambre étanche 80 destinée à être mise en pression.The articulated ends eA rigid tubes, the side of the yokes, are closed to form with the piston 75 in each of the rigid tubes, a sealed chamber 80 to be pressurized.

Le piston 75 est destiné à être déplacé longitudinalement dans le tube rigide par une pression dans la chambre 80 du tube rigide. Pour limiter le déplacement du piston, et donc éviter sa sortie du tube rigide, l'extrémité libre du tube rigide comporte une butée 90 solidaire du tube rigide et le fermant à cette extrémité. Par exemple cette butée est sous forme d'un joint torique entourant le tube semi-rigide 70, 71, 72, 73, 74.The piston 75 is intended to be moved longitudinally in the rigid tube by a pressure in the chamber 80 of the rigid tube. To limit the movement of the piston, and therefore avoid its exit from the rigid tube, the free end of the rigid tube comprises a stop 90 integral with the rigid tube and closing it at this end. For example, this stop is in the form of an O-ring surrounding the semi-rigid tube 70, 71, 72, 73, 74.

Chacun des tubes rigides comporte, en outre, un guide intermédiaire 92 pour guider une partie de l'extrémité du tube semi-rigide amené à se déplacer dans le tube rigide lors du déploiement du système.Each of the rigid tubes further comprises an intermediate guide 92 for guiding a portion of the end of the semi-rigid tube that is caused to move in the rigid tube during deployment of the system.

Dans la position du système replié dans son enveloppe de protection tel que représenté à la figure 1, le guide intermédiaire 92 est immobilisé dans une position prédéterminée pt dans une partie centrale du tube rigide entre le piston 75 et la butée 90.In the position of the folded system in its protective envelope as shown in FIG. figure 1 the intermediate guide 92 is immobilized in a predetermined position pt in a central part of the rigid tube between the piston 75 and the stop 90.

Le guide intermédiaire 92 peut être entraîné en translation dans le tube rigide lorsqu'un effort dépassant un certain seuil est exercé par le piston 75 sur le guide intermédiaire 92 selon l'axe longitudinal du tube rigide lors du déploiement du système de protection.The intermediate guide 92 can be driven in translation in the rigid tube when a force exceeding a certain threshold is exerted by the piston 75 on the intermediate guide 92 along the longitudinal axis of the rigid tube during the deployment of the protection system.

Selon la longueur du tube semi-rigide plusieurs guides intermédiaires peuvent être mis en place dans les tubes rigides.Depending on the length of the semi-rigid tube several intermediate guides can be placed in the rigid tubes.

Dans la position du système replié représenté à la figure 1, un angle d'incidence θ formé par les axes longitudinaux A1A1', B1B1', C1C1', D1D1', E1E1' et A2A2', B2B2', C2C2', D1D2', E2E2' des tubes rigides et l'axe longitudinal XX' du tube central ne doit pas être nul pour éviter un blocage lors du déploiement du système. A cet effet le tube central 10 comporte des butées d'incidence 94 sur la périphérie du tube central 10 et disposées sur le tube central de façon à ce que les extrémités libres des tubes rigides viennent en appui sur ces butées d'incidence pour former ledit angle d'incidence θ.In the position of the folded system represented in figure 1 , an angle of incidence θ formed by the longitudinal axes A 1 A 1 ', B 1 B 1 ', C 1 C 1 ', D 1 D 1 ', E 1 E 1 'and A 2 A 2 ', B 2 B 2 ', C 2 C 2 ', D 1 D 2 ', E 2 E 2 ' rigid tubes and the longitudinal axis XX 'of the central tube must not be zero to avoid blockage during deployment of the system. For this purpose the central tube 10 has abutment stops 94 on the periphery of the central tube 10 and arranged on the central tube so that the free ends of the rigid tubes bear on these bearing abutments to form said angle of incidence θ.

Le système comporte un dispositif de mise en pression des chambres 80 des tubes rigides (non représenté sur les figures) pour effectuer le déploiement de son armature 2.The system comprises a device for pressurizing the chambers 80 of the rigid tubes (not shown in the figures) to effect the deployment of its armature 2.

Dans une réalisation, les tubes rigides sont fermés, du côté de leurs extrémités eA articulées, par des flasques, un flasque droit 84 du côté d'une extrémité du tube central 10, (l'extrémité droite sur la figure 1) et un flasque gauche 86 du côté de l'autre extrémité (l'extrémité gauche sur la figure 1) du tube central. Les chambres 80 des tubes rigides sont mises en pression par la mise en pression des flasques 84, 86.In one embodiment, the rigid tubes are closed, on their articulated ends eA side, by flanges, a right flange 84 on the side of one end of the central tube 10, (the right end on the figure 1 ) and a left flange 86 on the side of the other end (the left end on the figure 1 ) of the central tube. The chambers 80 of the rigid tubes are pressurized by pressurizing the flanges 84, 86.

Dans cette réalisation, le dispositif de mise en pression des chambres des tubes rigides comporte une générateur de gaz pyrotechnique dans chacun des flasques 84, 86 de l'armature.In this embodiment, the device for pressurizing the chambers of the rigid tubes comprises a pyrotechnic gas generator in each of the flanges 84, 86 of the armature.

Dans une autre réalisation chaque tube rigide est ferme indépendamment du coté de son extrémité eA articulée. La mise en pression des chambres 80 des tubes rigides est faite indépendamment pour chacun des tubes rigides.In another embodiment each rigid tube is closed independently of the side of its articulated end eA. The pressurization of the chambers 80 of the rigid tubes is done independently for each of the rigid tubes.

Le dispositif de mise en pression des chambres des tubes rigides comporte un générateur de gaz pyrotechnique dans chacune des chambres 80 des tubes rigides.The device for pressurizing the chambers of the rigid tubes comprises a pyrotechnic gas generator in each of the chambers 80 of the rigid tubes.

Pour la mise en pression des chambres 80 des tubes rigides, le système comporte, par exemple, un dispositif électrique de mise à feu des générateurs des gaz pyrotechniques.For the pressurization of the chambers 80 of the rigid tubes, the system comprises, for example, an electric device for firing the pyrotechnic gas generators.

Le dispositif électrique peut être commandé par un calculateur destiné à détecter la menace et à déclencher le déploiement du système de protection.The electrical device can be controlled by a computer for detecting the threat and triggering the deployment of the protection system.

La toile 4 du système est configurée pour prendre une forme ovoïde lorsque le système est déployé (toile déployée représentée en pointillée aux figures 2a, 2b, 3b).The fabric 4 of the system is configured to take an ovoid shape when the system is deployed (deployed canvas represented in dashed line at Figures 2a , 2b , 3b ).

La toile 4 comporte à chacune de ses extrémité, d'un et de l'autre côté du tube central 10, une ouverture 100, 102 pour le passage des tubes rigides. La toile 4 est solidaire des tubes rigides et semi-rigides pour maintenir la toile en place sur l'armature 2. Par exemple des bords 104, 106 des ouvertures 100, 102 de la toile peuvent être solidaires des tubes rigides.The fabric 4 has at each end, on one side and on the other side of the central tube 10, an opening 100, 102 for the passage of the rigid tubes. The fabric 4 is integral with the rigid and semi-rigid tubes to hold the fabric in place on the frame 2. For example, the edges 104, 106 of the openings 100, 102 of the fabric may be integral with the rigid tubes.

En position du système replié, la toile 4 forme des plis 110 pour entrer dans l'enveloppe de protection 6 tel que représenté à la figure 1.In the folded system position, the fabric 4 forms folds 110 to enter the protective envelope 6 as shown in FIG. figure 1 .

En position déployé (voir figures 2a et 2b), la toile 4 du système présente des facettes formées par les paires de tubes rigides et leur tubes semi-rigides associés, une facette f8 formée par les paires consécutives P5 et P1de tubes rigides et leurs tubes semi-rigides associés, une autre facette f7 formée par les paires consécutives P4 et P5 de tubes rigides et leur tube semi-rigide associés.In deployed position (see Figures 2a and 2b ), the fabric 4 of the system has facets formed by the pairs of rigid tubes and their associated semi-rigid tubes, a facet f8 formed by the consecutive pairs P5 and P1 of rigid tubes and their associated semi-rigid tubes, another facet f7 formed by the consecutive P4 and P5 pairs of rigid tubes and their associated semi-rigid tube.

Le système comporte, en outre, des câbles de longueurs prédéterminés fixés à l'une et à l'autre des extrémités du tube central 10, pour donner une forme prédéterminé à la toile déployée.The system further comprises cables of predetermined lengths attached to one and the other end of the central tube 10, to give a predetermined shape to the deployed web.

Par exemple dans la réalisation montrée aux figures 2a et 2b le système comporte trois câbles CL1, CL, CL3 fixés d'un côté et de l'autre du tube central 10, chacun des câbles étant fixé entre deux chapes angulairement consécutives autour de l'axe XX' pour former des facettes supplémentaires sur la toile déployée et ainsi obtenir différentes incidences des facettes de la toile.For example in the realization shown to Figures 2a and 2b the system comprises three cables CL1, CL, CL3 fixed on one side and the other of the central tube 10, each of the cables being fixed between two angularly consecutive clevises around the axis XX 'to form additional facets on the fabric deployed and thus get different incidences of the facets of the canvas.

Un premier câble CL1 fixé d'un côté et de l'autre du tube central 10 entre les chapes de deux paires de tubes rigides angulairement consécutives d'axes A1A1' et B1B1'd'un côté du tube central et d'axes A2A2' et B2B2'de l'autre côté du tube central 10 pour former deux facettes f1 et f2 dans la partie de la toile comprise entre les deux paires P1 et P2 de tubes rigides et leurs tubes semi-rigides associées.A first cable CL1 fixed on one side and the other of the central tube 10 between the clevises of two pairs of angularly consecutive rigid tubes of axes A 1 A 1 'and B 1 B 1 ' on one side of the central tube and axes A 2 A 2 'and B 2 B 2 ' on the other side of the central tube 10 to form two facets f1 and f2 in the part of the fabric between the two pairs P1 and P2 of rigid tubes and their associated semi-rigid tubes.

Un deuxième câble CL2 fixé d'un côté et de l'autre du tube central 10 entre les chapes de deux paires de tubes rigides angulairement consécutives d'axes B1B1'et C1C1'd'un côté du tube central et d'axes B2B2' et C2C2' de l'autre côté du tube central 10 pour former deux facettes f3 et f4 dans la partie de la toile comprise entre les deux paires P2 et P3 de tubes rigides et leurs tubes semi-rigides associées.A second cable CL2 fixed on one side and the other of the central tube 10 between the clevises of two pairs of rigid angularly consecutive tubes of axes B 1 B 1 'and C 1 C 1 ' on one side of the central tube and axes B 2 B 2 'and C 2 C 2 ' on the other side of the central tube 10 to form two facets f3 and f4 in the part of the fabric between the two pairs P2 and P3 of rigid tubes and their associated semi-rigid tubes.

Un troisième câble CL3 fixé d'un côté et de l'autre du tube central 10 entre les chapes de deux paires de tubes rigides angulairement consécutives d'axes C1C1' et D1D1'd'un côté du tube central et d'axes C2C2' et D1D2'de l'autre côté du tube central 10 pour former deux facettes f5 et f6 dans la partie de la toile comprise entre les deux paires P3 et P4 de tubes rigides et leurs tubes semi-rigides associées.A third cable CL3 fixed on one side and the other of the central tube 10 between the clevises of two pairs of rigid angularly consecutive tubes of axes C 1 C 1 'and D 1 D 1 ' on one side of the central tube and axes C 2 C 2 'and D 1 D 2 ' on the other side of the central tube 10 to form two facets f5 and f6 in the part of the fabric between the two pairs P3 and P4 of rigid tubes and their associated semi-rigid tubes.

La toile 4 peut être réalisée à partir de plusieurs tronçons de toile assembles pour obtenir la forme ovoïde lorsqu'elle est déployée.The fabric 4 can be made from several sections of canvas assembled to obtain the ovoid shape when it is deployed.

La toile peut être réalisée à partir de matériaux souples et très résistants tel que poly-para-phénylène téréphtalamide commercialisé sous le nom déposé de Kevlar.The fabric can be made from flexible and very resistant materials such as poly-para-phenylene terephthalamide sold under the trade name Kevlar.

Le système de protection comporte, en outre, un dispositif de mise en pression des chambres 80 des tubes rigides pour déplacer les pistons 75 dans les tubes rigides et déployer l'armature.The protection system further comprises a device for pressurizing the chambers 80 of the rigid tubes to move the pistons 75 in the rigid tubes and deploy the armature.

Dans des variantes de réalisation du système déployable, les chapes peuvent inclure une butée en rotation angulaire des tubes rigides après déploiement de l'armature. En outre, les chapes peuvent aussi inclure une autre butée permettant d'obtenir l'angle d'incidence θ des tubes rigides en position de l'armature repliée, les butées d'incidences 94 sur le tube central ne sont alors plus nécessaires.In alternative embodiments of the deployable system, the yokes may include a stop in angular rotation of the rigid tubes after deployment of the frame. In addition, the yokes may also include another abutment for obtaining the angle of incidence θ of the rigid tubes in the position of the folded reinforcement, the bearing abutments 94 on the central tube are then no longer necessary.

Par la suite est décrit le fonctionnement du système de protection déployable selon l'invention.

  • La figure 3a montre une vue schématique en coupe axiale montrant le système selon l'invention en position replié.
  • La figure 3b montre une vue schématique en coupe axiale montrant le système selon l'invention en position déployé.
Next, the operation of the deployable protection system according to the invention is described.
  • The figure 3a shows a schematic view in axial section showing the system according to the invention in the folded position.
  • The figure 3b shows a schematic view in axial section showing the system according to the invention in the deployed position.

Dans la position du système replié de la figure 3a, le système de protection est enfermé dans l'enveloppe de protection 6 de section restreinte comportant à chacune des ses extrémité les flasque de fermeture 84, 86.In the folded system position of the figure 3a , the protection system is enclosed in the protective envelope 6 of restricted section having at each end the closing flange 84, 86.

Lors de l'actionnement du système de protection, l'enveloppe de protection 6 est ouverte pour permettre le déploiement de l'armature et de la toile de protection tel que décrit précédemment.When actuating the protection system, the protective envelope 6 is open to allow the deployment of the frame and the protective fabric as described above.

Comme cela a été précisé précédemment, à l'état de repos (système replié) les axes longitudinaux des tubes rigides de l'armature 4 forment avec l'axe XX' du tube central 10 un angle θ d'incidence faible mais jamais nul, afin de favoriser, en début de déploiement de l'armature, le développement de la forme devant être prise par le système. Les tubes rigides sont, dans la position du système replié, en appui par leur extrémité libre sur les butées d'incidence 94.As has been stated previously, in the idle state (folded system) the longitudinal axes of the rigid tubes of the armature 4 form with the axis XX 'of the central tube 10 an angle θ of low incidence but never zero, to promote, at the beginning of deployment of the frame, the development of the form to be taken by the system. Rigid tubes are, in the position of the folded system, supported by their free end on the bearing stops 94.

La valeur choisie pour cet angle d'incidence θ dépend des longueurs des tubes rigides et semi-rigides.The value chosen for this angle of incidence θ depends on the lengths of the rigid and semi-rigid tubes.

On considère la réalisation d'une mise en pression de la chambre 80 de chacun des tubes rigides 20, 24, 28, 32, 36, 22, 26 d'un côté et de l'autre côté 22, 26, 30, 34, 38 du tube central 10 par une capsule pyrotechnique logée dans la chambre 80 de chacun des tubes rigides. Un dispositif électrique (non représenté sur les figures) permet d'activer les capsules pyrotechniques dans les tubes rigides.It is considered to carry out a pressurization of the chamber 80 of each of the rigid tubes 20, 24, 28, 32, 36, 22, 26 on one side and the other side 22, 26, 30, 34, 38 of the central tube 10 by a pyrotechnic capsule housed in the chamber 80 of each of the rigid tubes. An electrical device (not shown in the figures) makes it possible to activate the pyrotechnic capsules in the rigid tubes.

Au moment du déploiement, qui doit être très rapide pour assurer une protection efficace par le système, les capsules de gaz pyrotechnique sont activées mettant en pression les chambres 80 des tubes rigides. Les piston 75 des tubes semi-rigides 70, 71, 72, 73, 74 sont alors poussés vers l'extrémités libres des tubes rigides qui subissent par lesdits pistons des efforts transversaux à l'axe XX' dans les respectifs plans pl1, pl2, pl3, pl4, pl5 des paires P1, P2, P3, P4, P5 de tubes rigides, faisant pivoter les extrémités articulées des tubes rigides en s'éloignant du tube central 10. Chacun des tubes semi-rigides 70, 71, 72, 73, 74 s'éloignant aussi du tube central poussé par ses pistons prends alors une forme d'arc qui est modulée par la présence de la toile 4 qu'ils entraînent dans leur déplacement.At the time of deployment, which must be very fast to ensure effective protection by the system, the pyrotechnic gas capsules are activated pressurizing the chambers 80 of the rigid tubes. The piston 75 of the semi-rigid tubes 70, 71, 72, 73, 74 are then pushed towards the free ends of the rigid tubes which undergo, by said pistons, forces transverse to the axis XX 'in the respective planes pl1, pl2, pl3, pl4, pl5 pairs P1, P2, P3, P4, P5 of rigid tubes, pivoting the articulated ends of the rigid tubes away from the central tube 10. Each of the semi-rigid tubes 70, 71, 72, 73 , 74 also moving away from the central tube pushed by its pistons take then a form of arc which is modulated by the presence of the canvas 4 which they involve in their displacement.

La commande de montée en pression des chambres 80 n'est pas obligatoirement simultanée. Un décalage temporel est acceptable.The pressure increase control of the chambers 80 is not necessarily simultaneous. A time shift is acceptable.

La figure 2b montre une vue en coupe schématique simplifiée en position du système déployé montrant les paires P1 et P4 de tubes rigides et leur tube semi-rigide 70, 73 associés dans les respectives plans axiaux pl1, pl4.The figure 2b shows a schematic simplified sectional view in position of the deployed system showing the pairs P1 and P4 of rigid tubes and their semi-rigid tube 70, 73 associated in the respective axial planes pl1, pl4.

Les pistons 75 des tubes semi-rigides poussés par les gaz sous pression dans chambres 80 des tubes rigides se déplacent dans les tubes rigides entraînant dans leur déplacement les guides intermédiaires 92 jusqu'aux butées 90, ce qui limité le déploiement de l'armature 2.The pistons 75 of the semi-rigid tubes pushed by the gases under pressure in chambers 80 of the rigid tubes move in the rigid tubes causing in their displacement the intermediate guides 92 to the stops 90, which limits the deployment of the frame 2 .

La longueur de l'arc formé par deux tubes rigides d'une paire et son respectif tube semi-rigide associé s'accroît au moment du déploiement du système ayant pour effet le déploiement de la toile qui prend alors sa forme ovoïde.The length of the arc formed by two rigid tubes of a pair and its respective associated semi-rigid tube increases at the time of the deployment of the system resulting in the deployment of the canvas which then takes its form ovoid.

L'armature 2 avec les câbles CL1, CL2, CL3 modulent la forme extérieure de la toile 4 formant les facettes f1 à f8 selon une forme globalement ovoïde.The armature 2 with the cables CL1, CL2, CL3 modulate the outer shape of the fabric 4 forming the facets f1 to f8 in a generally ovoid shape.

L'exemple décrit de système de protection selon l'invention n'est pas limitatif et l'armature peut comporter un nombre plus ou moins important de paires de tubes rigides et semi-rigides associés (par exemple entre 4 et 6 paires ainsi qu'un nombre variable de câbles intermédiaires afin d'obtenir une forme souhaitée de la toile dépliée.The described example of protection system according to the invention is not limiting and the armature may comprise a greater or lesser number of pairs of rigid and semi-rigid tubes associated (for example between 4 and 6 pairs and a variable number of intermediate cables to obtain a desired shape of the unfolded fabric.

Le système de protection selon l'invention comporte l'avantage d'une mise en oeuvre simplifiée, plus fiable, moins coûteux et plus facile d'entretien que les systèmes de l'état de l'art avec gonflage d'une toile de protection étanche.The protection system according to the invention has the advantage of a simplified implementation, more reliable, less expensive and easier to maintain than the systems of the state of the art with inflation of a protective cloth waterproof.
