Description

DOMAINE TECHNIQUETECHNICAL AREA

L'invention concerne un dispositif adaptateur destiné à être utilisé en association avec un projectile à ailettes déployables, tel qu'un missile, pour permettre le tir d'un tel projectile à partir d'un tube de lancement de faible diamètre, tel qu'un tube de mortier ou de canon.The invention relates to a device adapter for use in association with a projectile with deployable wings, such as a missile, to allow the firing of such a projectile from a small diameter launch tube, such than a tube of mortar or cannon.

L'invention permet notamment le tir de projectiles à guidage par fibres optiques, ou analogues, à partir d'un tube de lancement de dimensions standard, sans avoir à modifier celui-ci.The invention allows in particular the firing of projectiles with optical fiber guidance, or analogues, from a launch tube of standard dimensions, without having to modify this one.

ETAT DE LA TECHNIQUE ANTERIEURESTATE OF THE PRIOR ART

Comme l'illustre notamment le document US-A-4 907 763, il est connu de tirer un projectile guidé par un câble ou une fibre optique, à partir d'un tube de mortier ou de canon.As illustrated in particular in document US-A-4 907 763, it is known to shoot a guided projectile by cable or optical fiber, from a tube mortar or cannon.

Dans ce cas, le projectile est guidé en vol par des ailettes déployables qui viennent se loger avant le tir dans des évidements prévus à cet effet dans l'enveloppe extérieure dudit projectile. Cet agencement impose de monter les ailettes sur l'enveloppe par l'intermédiaire de mécanismes articulés complexes. De plus, la présence des évidements dans l'enveloppe extérieure du projectile conduit à réduire le volume utile disponible à l'intérieur de l'enveloppe du projectile. In this case, the projectile is guided in flight by deployable wings that come to lodge before firing in recesses provided for this purpose in the outer shell of said projectile. This arrangement makes it necessary to mount the fins on the envelope via articulated mechanisms complex. Moreover, the presence of the recesses in the outer shell of the projectile leads to reduce the useful volume available inside the envelope of the projectile.

EXPOSÉ DE L'INVENTIONSTATEMENT OF THE INVENTION

L'invention a précisément pour objet un dispositif adaptateur conçu pour permettre le tir d'un projectile tel qu'un missile à partir d'un tube de lancement standard de faible diamètre, tel qu'un tube de mortier ou de canon, sans modification dudit tube et sans nécessiter des logements ni des articulations complexes pour le montage des ailettes de guidage sur l'enveloppe extérieure du projectile.The subject of the invention is precisely a adapter device designed to allow the firing of a projectile such as a missile from a tube of standard launch of small diameter, such as a tube mortar or barrel, without modification of said tube and without requiring housing or joints complex for mounting guide vanes on the outer shell of the projectile.

Conformément à l'invention, ce résultat est obtenu au moyen d'un dispositif adaptateur conçu pour être interposé entre un projectile, muni d'ailettes déployables, aptes à occuper une position repliée, et un tube de lancement standard, ledit dispositif étant caractérisé en ce qu'il comprend une bague de retenue apte à être montée sur une extrémité ouverte du tube de lancement, un tube adaptateur apte à être placé autour du projectile, de telle sorte que les ailettes en position repliée soient logées dans une première partie du tube adaptateur, et des moyens d'accrochage du tube adaptateur sur la bague de retenue, dans une position telle que la première partie du tube adaptateur soit située à l'extérieur du tube de lancement et qu'une deuxième partie du tube adaptateur soit reçue dans le tube de lancement.According to the invention, this result is obtained by means of an adapter device designed to to be interposed between a projectile, provided with fins deployable, able to occupy a folded position, and a standard launching tube, said device being characterized in that it comprises a retaining ring adapted to be mounted on an open end of the tube of launch, an adapter tube able to be placed around of the projectile, so that the fins folded position are housed in a first part of the adapter tube, and means for attaching the tube adapter on the retaining ring, in a position such that the first part of the adapter tube is located outside the launch tube and that a second part of the adapter tube is received in the launch tube.

L'utilisation du dispositif adaptateur conforme à l'invention permet de tirer un projectile muni d'ailettes déployables à partir d'un tube de lancement standard dont le diamètre intérieur est à peine supérieur au diamètre intérieur du corps du projectile, sans qu'il soit nécessaire de modifier le tube de lancement. En effet, la bague de retenue montée sur le tube de lancement sert d'ancrage aux moyens d'accrochage du tube adaptateur dans lequel est placé le projectile. Le montage de la bague de retenue sur le tube de lancement peut notamment être réalisé par friction, en donnant à ladite bague la forme d'une bague fendue que l'on serre à l'aide d'un boulon interposé entre ses extrémités. Les ailettes repliées du projectile sont reçues dans la partie avant du tube adaptateur, qui sert de guidage au projectile lorsque le tir est effectué.Using the adapter device according to the invention makes it possible to fire a projectile equipped with deployable fins from a tube of standard launch whose inside diameter is at hardly greater than the inside diameter of the body of the projectile without the need to modify the launch tube. Indeed, the mounted retaining ring on the launch tube serves as anchor to the means hanging from the adapter tube in which is placed the projectile. The mounting of the retaining ring on the launch tube can in particular be realized by friction, by giving said ring the shape of a Split ring that is tightened with a bolt interposed between its ends. The wings folded of the projectile are received in the front part of the tube adapter, which serves as a guidance to the projectile when shooting is done.

Selon un mode de réalisation préféré de l'invention, la première partie du tube adaptateur comprend des rainures de guidage longitudinal débouchant à l'intérieur du tube adaptateur, de façon à pouvoir recevoir chacune des ailettes du projectile.According to a preferred embodiment of the invention, the first part of the adapter tube includes longitudinal guide grooves opening inside the adapter tube, so that to be able to receive each wing of the projectile.

Dans ce cas, la première partie du tube comprend avantageusement des nervures extérieures longitudinales et chacune desdites rainures de guidage longitudinal est formée dans l'une correspondante desdites nervures extérieures longitudinales.In this case, the first part of the tube advantageously comprises external ribs longitudinal and each of said guide grooves longitudinal is formed in the corresponding one said longitudinal outer ribs.

Selon une réalisation avantageuse de l'invention, la première partie du tube comprend une bague extérieure adjacente à la deuxième partie du tube adaptateur et apte à venir en appui contre une extrémité ouverte du tube de lancement.According to an advantageous embodiment of the invention, the first part of the tube comprises a outer ring adjacent to the second part of the tube adapter and able to come to bear against a open end of the launch tube.

Avantageusement, les moyens d'accrochage sont alors interposés entre la bague de retenue et la bague extérieure du tube adaptateur. Advantageously, the attachment means are then interposed between the retaining ring and the outer ring of the adapter tube.

Dans ce cas, les moyens d'accrochage peuvent notamment comprendre des mécanismes à grenouillère.In this case, the attachment means may include mechanisms to onesie.

Selon un perfectionnement avantageux, le dispositif comprend de plus des éléments de transport amovibles incluant un bouchon de protection avant et un bouchon de protection arrière, aptes à être placés respectivement sur les extrémités avant et arrière du projectile recouvert du tube adaptateur, et une sangle de transport reliant lesdits bouchons de protection.According to an advantageous improvement, the device further comprises transport elements removable ones including a front protection cap and a rear protection cap, suitable for placing respectively on the front and rear ends of the projectile covered tube adapter, and a strap transporting said protective caps.

De préférence, une extrémité ouverte du tube adaptateur, opposée à la deuxième partie de celui-ci, est prévue pour être placée derrière des propulseurs auxiliaires du projectile.Preferably, an open end of adapter tube, opposite to the second part of it, is intended to be placed behind auxiliary propellants of the projectile.

Avantageusement, le projectile est un missile à guidage par fibre optique.Advantageously, the projectile is a fiber optic guided missile.

Dans ce cas, le tube adaptateur comprend généralement une extrémité fermée, opposée à la première partie de celui-ci, et une poulie de renvoi de la fibre optique, montée à l'intérieur de ladite extrémité fermée.In this case, the adapter tube includes usually a closed end, opposite the first part of it, and a pulley the optical fiber mounted inside said closed end.

Enfin, le tube de lancement est avantageusement un tube de mortier.Finally, the launch tube is advantageously a mortar tube.

    • EXPOSE DETAILLE D'UN MODE DE REALISATION PREFEREDETAILED DESCRIPTION OF A PREFERRED EMBODIMENT

    Dans l'ensemble de la description, les termes "avant" et "arrière" font référence respectivement à l'avant et à l'arrière du projectile placé dans le tube de lancement par l'intermédiaire du dispositif adaptateur.Throughout the description, the terms "forward" and "backward" refer to respectively at the front and the rear of the projectile placed in the launch tube through the adapter device.

    Comme on l'a illustré schématiquement sur la figure 1, l'invention concerne un dispositif adaptateur 10 prévu pour être interposé entre un projectile 12 tel qu'un missile à guidage par fibre optique et un tube de lancement standard 14 tel qu'un tube de mortier, afin de permettre un tir du projectile 12 sans qu'il soit nécessaire de modifier le tube de lancement.As schematically illustrated on FIG. 1, the invention relates to a device adapter 10 intended to be interposed between a projectile 12 such as a fiber guided missile optical and a standard launch tube 14 such as a mortar tube, to allow a shot of the projectile 12 without it being necessary to modify the tube of launch.

    Plus précisément, le projectile 12 comprend un corps cylindrique sur lequel sont articulées des ailettes 16 (figure 2) aptes à occuper une position repliée illustrée en trait plein et une position déployée (non représentée). Dans le mode de réalisation non limitatif représenté sur les figures, les ailettes 16 sont au nombre de quatre, régulièrement réparties sur la circonférence du corps du projectile. Chacune des ailettes 16 est plane et située dans un plan passant par l'axe longitudinal du corps du projectile. Par rapport à son axe 18 d'articulation sur le corps du projectile, chaque ailette 16 est apte à se replier vers l'avant du projectile 12, de telle sorte que son bord tourné vers l'avant lorsque les ailettes sont déployées vient se placer contre la surface circonférentielle du corps du projectile lorsque les ailettes 16 sont repliées.More specifically, the projectile 12 comprises a cylindrical body on which are articulated fins 16 (Figure 2) able to occupy a position folded illustrated in solid lines and a position deployed (not shown). In the embodiment non-limiting embodiment shown in the figures, the fins 16 are four, regularly distributed on the circumference of the body of the projectile. Each fins 16 is flat and located in a plane passing through the longitudinal axis of the body of the projectile. With respect to its articulation axis 18 on the body of the projectile, each fin 16 is capable of folding towards the front of the projectile 12, so that its edge turned forward when the fins are deployed comes up against the surface circumference of the projectile body when the fins 16 are folded.

    Comme on le voit également sur la figure 1, le projectile 12 comprend aussi des propulseurs d'appoint 18 (par exemple au nombre de deux) qui débouchent sur la surface circonférentielle du corps du projectile, à l'avant des ailettes 16 lorsque celles-ci sont en position repliée.As can also be seen in FIG. the projectile 12 also includes thrusters 18 (for example the number of two) who lead to the circumferential surface of the body of the projectile, at the front of the fins 16 when these are in the folded position.

    Comme on l'a indiqué précédemment, le projectile 12 est guidé par une fibre optique 20 utilisée, de façon connue, pour assurer la transmission d'informations entre ledit projectile et un poste de commande (non représenté), après le tir du projectile. La fibre optique 20 est emmagasinée sur une bobine 21 placée dans la partie arrière du corps du projectile 12. Elle sort dudit corps par un orifice central formé sur la face arrière de celui-ci. La fibre optique 20 chemine ensuite le long de la paroi interne du tube 14 ou à l'extérieur du corps du projectile 12, selon une trajectoire qui sera précisée par la suite, avant de ressortir par l'extrémité ouverte du tube de lancement 14 pour rejoindre le poste de commande. As noted above, the projectile 12 is guided by an optical fiber 20 used, in known manner, to ensure the transmission information between said projectile and a command (not shown), after firing the projectile. The optical fiber 20 is stored on a coil 21 placed in the rear part of the body of the projectile 12. It exits said body through a central hole formed on the back side of it. The optical fiber 20 then travels along the inner wall of the tube 14 or outside the body of the projectile 12, according to a trajectory that will be specified later, before exit through the open end of the launch tube 14 to join the command post.

    Le dispositif adaptateur 10 conforme à l'invention comprend essentiellement une bague de retenue 22, prévue pour être fixée sur l'extrémité ouverte du tube de lancement 14, un tube adaptateur 24 conçu pour être placé autour du corps du projectile 12 et des moyens d'accrochage 26 du tube adaptateur 24 sur la bague de retenue 22.The adapter device 10 according to the invention essentially comprises a ring of retainer 22, intended to be attached to the end open launch tube 14, an adapter tube 24 designed to be placed around the body of the projectile 12 and attachment means 26 of the adapter tube 24 on the retaining ring 22.

    La bague de retenue 22 est prévue pour être fixée par serrage sur le tube de lancement 14, à proximité immédiate de son extrémité ouverte, sans qu'il soit nécessaire d'effectuer une modification ou un usinage quelconque dudit tube. Ainsi, la bague de retenue 22 peut notamment être une bague fendue dont les extrémités peuvent être rapprochées l'une de l'autre par un dispositif de serrage rapide tel qu'un boulon 28. Le serrage du boulon 28 a pour effet de solidariser par friction la bague de retenue 22 de l'extrémité du tube de lancement 14.The retaining ring 22 is intended to be clamped on the launch tube 14, to immediate proximity to its open end, without that it is necessary to make a modification or any machining of said tube. So, the ring of retainer 22 may especially be a split ring of which the ends can be brought closer to one of the other by a quick-clamping device such as a bolt 28. The tightening of the bolt 28 has the effect of frictionally fasten the retaining ring 22 of the end of the launch tube 14.

    Sur sa surface extérieure, la bague de retenue 22 porte une partie des moyens d'accrochage 26 destinés à immobiliser le tube adaptateur 24 par rapport à ladite bague lorsqu'un ensemble projectile 12 - tube adaptateur 24 est placé sur le tube de lancement 14. Dans le mode de réalisation représenté à titre d'exemple sur les figures, ladite partie des moyens d'accrochage 26 comprend deux mécanismes à grenouillères 30 montés en des emplacements diamétralement opposés sur la surface extérieure de la bague de retenue 22.On its outer surface, the ring of retaining 22 carries part of the attachment means 26 intended to immobilize the adapter tube 24 by relative to said ring when a projectile assembly 12 - adapter tube 24 is placed on the launch tube 14. In the embodiment shown in example in the figures, said part of the means of attachment 26 comprises two mechanisms to toggle switches 30 mounted in locations diametrically opposite on the outer surface of the retaining ring 22.

    Comme l'illustre la figure 1, le tube adaptateur 24 est un tube de longueur légèrement inférieure à celle du projectile 12 et dont le diamètre intérieur est uniforme et légèrement supérieur au diamètre extérieur du corps du projectile. L'extrémité avant du tube adaptateur 24 est ouverte alors que l'extrémité arrière dudit tube est fermée par un fond 32.As illustrated in Figure 1, the tube adapter 24 is a tube of slightly length less than that of the projectile 12 and whose diameter interior is uniform and slightly higher than outer diameter of the body of the projectile. The end before adapter tube 24 is open while the rear end of said tube is closed by a bottom 32.

    Ainsi, le tube adaptateur 24 peut être placé autour du corps du projectile 12, de telle sorte que l'extrémité avant du projectile 12 fasse saillie sur une certaine longueur hors de l'extrémité avant ouverte du tube adaptateur 24. L'extrémité arrière du projectile 12 est alors située à l'intérieur du tube adaptateur 24, à une certaine distance du fond 32 dudit tube. Cette dernière distance est déterminée par la venue en appui, contre l'extrémité avant ouverte du tube de lancement 14, d'une bague extérieure 34 qui fait partie intégrante du tube adaptateur 24.Thus, the adapter tube 24 can be placed around the body of the projectile 12, so that the front end of the projectile 12 protrudes on a certain length out of the front end open end of the adapter tube 24. The rear end of the projectile 12 is then located inside the tube adapter 24, at a distance from the bottom 32 of said tube. This last distance is determined by the supported against the open front end of the launch tube 14, an outer ring 34 which is an integral part of the adapter tube 24.

    Comme le montre la figure 1, cet agencement permet de monter une poulie de renvoi 36 de la fibre optique 20 sur la face intérieure du fond 32 du tube adaptateur 24. A la sortie de l'extrémité arrière du projectile 12, la fibre optique 20 chemine sur la poulie de renvoi 36 et revient jusqu'à l'extrémité avant ouverte du tube de lancement 14, entre le tube adaptateur 24 et le projectile 12, pour se diriger ensuite vers le poste de commande (non représenté). Plus précisément, la partie de la fibre optique 20 qui chemine entre le tube adaptateur 24 et le projectile 12 passe dans une gaine (non représentée) prévue à cet effet à l'intérieur du tube adaptateur. Cette gaine assure la protection mécanique et thermique de la fibre optique 20 lors du lancement du projectile 12.As shown in Figure 1, this arrangement allows to mount a pulley 36 of the fiber optical 20 on the inner face of the bottom 32 of the tube 24. At the exit from the rear end of the projectile 12, the optical fiber 20 travels on the return pulley 36 and returns to the end open front of the launch tube 14, between the tube adapter 24 and the projectile 12, to go then to the control station (not shown). More specifically, the part of the optical fiber 20 which between the adapter tube 24 and the projectile 12 pass in a sheath (not shown) provided for this effect inside the adapter tube. This sheath ensures the mechanical and thermal protection of the fiber optical 20 when launching the projectile 12.

    La bague extérieure 34 est munie d'une autre partie des moyens d'accrochage 26 du tube adaptateur 24 sur le tube de lancement 12. Dans le mode de réalisation représenté, cette autre partie des moyens d'accrochage 26 comprend deux crochets 48 situés en des emplacements diamétralement opposés sur la surface extérieure de ladite bague extérieure 34. Les mécanismes à grenouillères 30 montés sur la bague de retenue 22 sont agencés de façon à pouvoir venir en prise sur les crochets 48 lorsque le tube adaptateur 24 est placé dans le tube de lancement 14. Le tube adaptateur 24 est alors immobilisé par rapport au tube de lancement 14.The outer ring 34 is provided with a other part of the hooking means 26 of the tube adapter 24 on the launch tube 12. In the shown, this other part of fastening means 26 comprises two hooks 48 located in diametrically opposed locations on the outer surface of said outer ring 34. latching mechanisms 30 mounted on the ring of 22 are arranged so as to be able to come into taken on the hooks 48 when the adapter tube 24 is placed in the launch tube 14. The tube adapter 24 is then immobilized relative to the tube launch 14.

    La bague extérieure 34 est située sensiblement au milieu du tube adaptateur 24 et sépare celle-ci en une première partie 38, située en avant de ladite bague extérieure et une deuxième partie 40 située en arrière de ladite bague extérieure.The outer ring 34 is located substantially in the middle of the adapter tube 24 and separates it in a first part 38, located in front of said outer ring and a second part 40 located behind said outer ring.

    La première partie 38 du tube adaptateur 24 comprend des rainures de guidage longitudinal 42 (figure 2) dont chacune est prévue pour recevoir l'une des ailettes 16 du projectile 12. Plus précisément, chacune des rainures de guidage longitudinal 42 est formée dans une nervure extérieure longitudinale 44 du tube adaptateur 24 et débouche à l'intérieur dudit tube sur toute sa longueur. En outre, le nombre et la répartition des nervures 44 autour du tube adaptateur 24 et le nombre et la répartition des ailettes 16 autour du corps du projectile 12 sont identiques. Dans le mode de réalisation représenté, il existe quatre ailettes 16 et quatre nervures 44, régulièrement réparties autour du corps du projectile 12 et autour du tube adaptateur 24, respectivement. Chacune des rainures de guidage longitudinal 42 débouche également à son extrémité avant, de telle sorte que le projectile puisse être introduit et extrait du tube adaptateur 24 par l'avant de celui-ci.The first part 38 of the adapter tube 24 includes longitudinal guide grooves 42 (Figure 2) each of which is intended to receive one fins 16 of the projectile 12. More precisely, each of the longitudinal guide grooves 42 is formed in a longitudinal outer rib 44 of the 24 adapter tube and opens inside said tube over its entire length. In addition, the number and distribution of the ribs 44 around the adapter tube 24 and the number and distribution of fins 16 around the body of the projectile 12 are identical. In the embodiment shown, there are four fins 16 and four ribs 44, regularly distributed around the body of the projectile 12 and around the adapter tube 24, respectively. Each of the longitudinal guide grooves 42 also opens at its front end, so that the projectile can be introduced and extracted from the adapter tube 24 by the front of it.

    L'extrémité avant de la première partie 38 du tube adaptateur 24 est renforcée par une bague extérieure segmentée 46, entre les nervures extérieures longitudinales 44.The front end of the first part 38 of the adapter tube 24 is reinforced by a ring outer segment 46, between the outer ribs longitudinal 44.

    La deuxième partie 40 du tube adaptateur 24, située en arrière de la bague extérieure 34, présente un diamètre extérieur uniforme, légèrement inférieur au diamètre intérieur du tube de lancement 14 à partir duquel le projectile doit être tiré. Ainsi, la deuxième partie 40 du tube adaptateur 24 peut être introduite par l'extrémité avant ouverte du tube de lancement 14, après que la bague de retenue 22 a été montée sur le tube de lancement 14.The second part 40 of the adapter tube 24, located behind the outer ring 34, has a uniform outer diameter, slightly less than the inside diameter of the launch tube 14 from which the projectile must be fired. So, the second part 40 of the adapter tube 24 can be introduced by the open front end of the tube launch 14, after the retaining ring 22 has been mounted on the launch tube 14.

    Grâce à l'agencement qui vient d'être décrit en se référant aux figures 1 et 2, il est possible de tirer un projectile 12 guidé par une fibre optique 20 et muni d'ailettes extérieures 16 repliables mais non escamotables à l'intérieur du corps du projectile, depuis un tube de lancement 14 non prévu à cet effet, sans aucune modification dudit tube.Thanks to the arrangement that has just been described with reference to FIGS. 1 and 2, it is possible to fire a projectile 12 guided by a fiber optical 20 and provided with 16 folding outer wings but not retractable inside the body of the projectile, from a launch tube 14 not provided for in this effect, without any modification of said tube.

    Ce résultat est rendu possible grâce à l'utilisation d'un tube adaptateur 24 servant d'interface entre le projectile 12 et le tube de lancement 24 et grâce au montage d'une bague de retenue 22 sur le tube de lancement 14, le tube adaptateur 24 pouvant être aisément fixé à la bague de retenue 22 par les moyens d'accrochage 26.This result is made possible thanks to the use of an adapter tube 24 serving interface between the projectile 12 and the tube of launch 24 and thanks to the installation of a retaining ring 22 on the launch tube 14, the adapter tube 24 can be easily attached to the retaining ring 22 by the attachment means 26.

    Les nervures 44 formées sur la partie avant du tube adaptateur 24 sont utilisées pour assurer le guidage des ailettes 16 repliées du projectile 12, lors de son lancement. Les propulseurs d'appoint 18 sont alors placés devant la bague extérieure segmentée 46 qui délimite l'extrémité avant de la partie avant du tube adaptateur 24. Les jets émis par ces propulseurs 18 prennent donc appui sur ladite bague 46 lors de la mise à feu.The ribs 44 formed on the front part adapter tube 24 are used to ensure the guidance of the folded fins 16 of the projectile 12, when of its launch. The booster thrusters 18 are then placed in front of the segmented outer ring 46 which delimits the front end of the front part of the adapter tube 24. The jets emitted by these thrusters 18 thus bear on said ring 46 during the Firing.

    Comme on l'a illustré sur la figure 3, l'ensemble formé par le projectile 12 et par le dispositif adaptateur 10 est prévu pour être transporté aisément sur le site de tir, où se trouve le tube de lancement 14.As illustrated in Figure 3, the whole formed by the projectile 12 and the adapter device 10 is intended to be transported easily on the shooting site, where is the tube of launch 14.

    A cet effet, le dispositif adaptateur 10 comprend de plus un bouchon de protection avant 48, prévu pour être placé sur l'extrémité avant du projectile 12, un bouchon de protection arrière 50, prévu pour être placé sur l'extrémité arrière du tube adaptateur 24, fermée par le fond 32, ainsi qu'une sangle de transport 52, qui relie les bouchons de protection avant 48 et arrière 50. Les bouchons 48 et 50 forment avec la sangle 52 des éléments de transport amovibles de l'ensemble constitué par le projectile 12 et son tube adaptateur 24. Ces éléments de transport amovibles sont déposés lors de l'arrivée sur le site de lancement.For this purpose, the adapter device 10 further includes a protective cap before 48, intended to be placed on the front end of the projectile 12, a rear protective cap 50, intended to be placed on the rear end of the tube adapter 24, closed by the bottom 32, as well as a transport strap 52, which connects the plugs of front 48 and rear 50 protection. 50 form with the strap 52 of the transport elements removable from the assembly formed by the projectile 12 and its adapter tube 24. These transport elements removable are deposited upon arrival at the site of launch.
