Definitions
- the invention relates to an explosive projectile. suitable for spraying active material.
- the active ingredient can be made up of a material generating splinters, by example a prefragmented wall or envelope, a incendiary or smoke-producing material.

- This arrangement allows a projectile to even small caliber to carry a significant amount explosive charge and active material, this quantity being proportional to the useful length of the projectile.
- This classic projectile presents the main disadvantage that the active ingredient found projected radially in all directions around the axis of the projectile, so that a weak some of this active ingredient is actually useful against a point target.

- An explosive projectile is thus obtained in which the explosive charge and the active material can be arranged over the effective length of the projectile and thus represent significant quantities compared the caliber of said projectile.
- These large quantities explosive charge and active ingredient can be used extremely effectively against a target as soon as this target is in the direction in which the active material is projected contained in the various subsets.
- each subset is made substantially in the form of a cylindrical sector pivotally mounted so as to pivot radially outward relative to the body of the projectile.
- Each sector-shaped subset can thus have a length in the direction of the axis of the projectile equal to the useful dimension of the latter, this which allows to project, according to the chosen direction, a maximum amount of active ingredient, taking into account the diameter of the projectile.
- the cylindrical sector sub-assemblies are identical, are distributed regularly around the axis of the projectile, and are adapted to pivot about 90 degrees from the body of the projectile.

- This common direction is advantageously the direction of axis 8 of projectile 1.
- each subset 5 is produced substantially in the form of a cylindrical sector pivotally mounted around an axis 9 relative to the body 7 of the projectile 1, so as to pivot radially outwards by relative to the body 7 of the projectile 1.
- each sub-assembly 5 In its retracted position inside the body 7 of projectile 1 (see figures 1 and 3), each sub-assembly 5 extends axially substantially over the entire useful length of said body 7.
- the subsets 5 in form of cylindrical sectors are identical, are evenly distributed around axis 8 of the projectile 1, and are adapted to rotate about 90 degrees by relation to the body 7.
- FIGS. four are shown. sectors arranged at 90 degrees to each other the other and extending angularly at an angle of About 90 degrees.

- Projectile 1 includes a rocket programmable 17 which conventionally controls the setting with explosive charges.
- This programmable rocket 17 also includes means, shown schematically in 18 and known in themselves, to order or prohibit the deployment of the various sub-assemblies 5.
- This rocket 17 can be programmed before firing or on trajectory. It will be understood that it is also possible not to order the deployment of the sub-assemblies. In these conditions, the ignition of the explosive charge of each subset 5 projects the different shards substantially radially, and the explosive projectile behaves like a conventional projectile by projecting a lateral burst of splinters, as shown schematically in the figure 5. In this case, only the part of the sheaf of shrapnel included in the angular sector defined by the arrow 25 constitutes the part of this sheaf useful against the target 19.
- the body 7 of the projectile 1 comprises a central edge 20 which supports the pivot axes 9 and the different sub-assemblies 5 in their retracted position.

Description
L'invention concerne un projectile explosif adapté à projeter de la matière active.The invention relates to an explosive projectile. suitable for spraying active material.
On sait que la matière active peut être constituée d'une matière génératrice d'éclats, par exemple une paroi ou une enveloppe préfragmentée, une matière incendiaire ou une matière fumigène.We know that the active ingredient can be made up of a material generating splinters, by example a prefragmented wall or envelope, a incendiary or smoke-producing material.
On connaít de nombreux types de projectile explosif adaptés à projeter de la matière active, contenant au moins une charge explosive, des moyens d'amorçage de la charge explosive et de la matière active.We know many types of projectile explosive suitable for projecting active material, containing at least one explosive charge, means initiating the explosive charge and the material active.
Dans un projectile explosif classique, la charge explosive et la matière active sont disposées concentriquement par rapport à l'axe longitudinal du projectile. Cette disposition permet à un projectile de calibre même petit d'emporter une quantité importante de charge explosive et de matière active, cette quantité étant proportionnelle à la longueur utile du projectile. Ce projectile classique présente l'inconvénient principal que la matière active se trouve projetée radialement dans toutes les directions autour de l'axe du projectile, de sorte qu'une faible partie de cette matière active est réellement utile contre une cible ponctuelle.In a conventional explosive projectile, the explosive charge and the active ingredient are arranged concentrically with respect to the longitudinal axis of the projectile. This arrangement allows a projectile to even small caliber to carry a significant amount explosive charge and active material, this quantity being proportional to the useful length of the projectile. This classic projectile presents the main disadvantage that the active ingredient found projected radially in all directions around the axis of the projectile, so that a weak some of this active ingredient is actually useful against a point target.
On connaít également, d'après le FR-A-2 388 468, un projectile du type précité comportant des moyens d'aplatissement de l'enveloppe disposés sensiblement en périphérie de celle-ci et couvrant au moins un secteur angulairement limité par rapport à l'axe, ainsi que des moyens de détection de la direction d'une cible par rapport à l'axe associés aux moyens d'aplatissement pour provoquer de manière sélective un aplatissement de l'enveloppe et de la charge sensiblement en regard de ladite cible. L'aplatissement de l'enveloppe et de la charge a pour effet d'assurer la projection des fragments de la zone aplatie de l'enveloppe dans une direction sensiblement perpendiculaire à cet aplatissement, ce qui assure la concentration désirée des fragments en direction de la cible. Cette structure permet d'augmenter la partie utile de la matière active par rapport à un projectile explosif classique, mais cette partie active augmentée ne représente encore qu'une faible proportion de la partie active emportée par le projectile.We also know, from FR-A-2 388 468, a projectile of the aforementioned type comprising envelope flattening means arranged substantially on the periphery thereof and covering at minus an angularly limited sector compared to the axis, as well as means for detecting the direction of a target relative to the axis associated with flattening means for provoking so selective flattening of the envelope and the load substantially opposite said target. The flattening of the envelope and the load has the effect to ensure the projection of the fragments of the flattened area of the envelope in a direction substantially perpendicular to this flattening, which ensures the desired concentration of fragments towards the target. This structure allows increase the useful part of the active ingredient compared to a conventional explosive projectile, but this active part still only represents a small proportion of the active part carried by the projectile.
On connaít également un projectile explosif dans lequel la charge explosive et la matière active sont concentrées sur toute la section droite du projectile, par exemple à l'avant de celui-ci. On peut ainsi obtenir une gerbe de matière active frontale ou hémisphérique suivant la disposition de la charge explosive. Toutefois, les quantités respectives de charge explosive et de matière active emportées par le projectile sont faibles dans la mesure où cette charge et cette matière sont disposées selon la section droite du projectile sur une longueur axiale faible de ce dernier.We also know of an explosive projectile in which the explosive charge and the active material are concentrated over the entire cross section of the projectile, by example at the front of it. We can thus obtain a spray of frontal or hemispherical active material depending on the disposal of the explosive charge. However, the quantities respective explosive charge and active ingredient carried by the projectile are weak insofar as this charge and this material are arranged according to the section right of the projectile over a short axial length of this latest.
Le brevet US4798143 décrit un projectile permettant de disperser une matière active derrière une paroi d'aéronef. Ce projectile comporte une pointe qui assure le percement de la paroi et qui joue le rôle de diffuseur de la matière active. Il comporte également des volets déployables. Ces volets prennent appui sur la paroi et ont pour objet de stopper la pénétration complète du projectile au travers de la paroi. Si ce projectile permet de diffuser une matière active, il ne peut la diffuser que dans une seule direction et derrière une paroi et non sur trajectoire.Patent US4798143 describes a projectile for dispersing an active ingredient behind a wall of aircraft. This projectile has a point which ensures the piercing of the wall and which plays the role of diffuser of the active ingredient. It also has deployable flaps. These flaps are supported on the wall and are intended to stop the complete penetration of the projectile through Wall. If this projectile allows to diffuse a matter active, it can only broadcast it in one direction and behind a wall and not on a trajectory.
Le but de la présente invention est de remédier aux inconvénients des projectiles explosifs connus, et de proposer un projectile explosif du type précité capable d'emporter des quantités respectives importantes de charge explosive et de matière active par rapport au calibre dudit projectile, tout en étant également capable de projeter la matière active sensiblement dans une direction unique.The object of the present invention is to remedy to the disadvantages of known explosive projectiles, and propose an explosive projectile of the aforementioned type capable to carry significant respective amounts of load explosive and active material compared to the caliber of said projectile, while also being able to project the active ingredient substantially in a single direction.
Le projectile explosif visé par l'invention est un projectile explosif du type précité contenant des moyens pour concentrer au moins une partie de la matière active en direction d'une cible lors de l'explosion de ladite charge explosive. The explosive projectile targeted by the invention is a explosive projectile of the aforementioned type containing means for concentrate at least part of the active ingredient in direction of a target during the explosion of said charge explosive.
Suivant l'invention, ce projectile est caractérisé en ce que la charge explosive et la matière active sont disposées selon des sous-ensembles montés chacun sur un support, chaque support étant monté de façon mobile par rapport au corps du projectile, et en ce que ledit projectile comporte des moyens pour faire passer chaque sous-ensemble d'une position rentrée à l'intérieur du projectile à une position déployée par rapport au corps du projectile, les positions déployées respectives des divers sous-ensembles étant prédéterminées de façon telle que lors de l'explosion de la charge explosive, la matière active contenue dans les divers sous-ensembles soit projetée sensiblement dans une même direction.According to the invention, this projectile is characterized in that the explosive charge and the material active are arranged in mounted sub-assemblies each on a support, each support being mounted movable relative to the body of the projectile, and what said projectile has means for doing pass each subset from retracted position to inside the projectile in a position deployed by relative to the body of the projectile, the deployed positions respective of the various subsets being predetermined in such a way that during the explosion explosive charge, the active ingredient in the various sub-assemblies is projected substantially in the same direction.
On obtient ainsi un projectile explosif dans lequel la charge explosive et la matière active peuvent être disposées sur la longueur utile du projectile et représenter ainsi des quantités importantes par rapport au calibre dudit projectile. Ces quantités importantes de charge explosive et de matière active peuvent être utilisées de manière extrêmement efficace contre une cible dès lors que cette cible se trouve dans la direction dans laquelle est projetée la matière active contenue dans les divers sous-ensembles.An explosive projectile is thus obtained in which the explosive charge and the active material can be arranged over the effective length of the projectile and thus represent significant quantities compared the caliber of said projectile. These large quantities explosive charge and active ingredient can be used extremely effectively against a target as soon as this target is in the direction in which the active material is projected contained in the various subsets.
Suivant une version avantageuse de l'invention, chaque sous-ensemble est réalisé sensiblement sous la forme d'un secteur cylindrique monté de manière pivotante de façon à pivoter radialement vers l'extérieur par rapport au corps du projectile.According to an advantageous version of the invention, each subset is made substantially in the form of a cylindrical sector pivotally mounted so as to pivot radially outward relative to the body of the projectile.
Chaque sous-ensemble en forme de secteur peut ainsi avoir une longueur dans la direction de l'axe du projectile égale à la dimension utile de ce dernier, ce qui permet de projeter, suivant la direction choisie, une quantité de matière active maximale, compte tenu du diamètre du projectile. Each sector-shaped subset can thus have a length in the direction of the axis of the projectile equal to the useful dimension of the latter, this which allows to project, according to the chosen direction, a maximum amount of active ingredient, taking into account the diameter of the projectile.
Selon une version avantageuse de l'invention, les sous-ensembles en forme de secteur cylindrique sont identiques, sont répartis régulièrement autour de l'axe du projectile, et sont adaptés à pivoter d'environ 90 degrés par rapport au corps du projectile. On peut ainsi réaliser une concentration importante de la matière active projetée sensiblement dans la direction de l'axe du projectile.According to an advantageous version of the invention, the cylindrical sector sub-assemblies are identical, are distributed regularly around the axis of the projectile, and are adapted to pivot about 90 degrees from the body of the projectile. We can thus achieve a significant concentration of the active material projected substantially in the direction of the projectile axis.
Selon une version préférée de l'invention, le projectile explosif comporte une fusée programmable comportant des moyens pour commander ou interdire le déploiement des divers sous-ensembles.According to a preferred version of the invention, the explosive projectile features a programmable rocket comprising means for controlling or prohibiting the deployment of the various sub-assemblies.
Le projectile est ainsi capable de réaliser une concentration de la matière active dans la direction de l'axe du projectile, ou de fonctionner comme un projectile explosif classique avec projection radiale de ladite matière active.The projectile is thus capable of achieving a concentration of the active ingredient in the direction of the projectile axis, or to function like a conventional explosive projectile with projection radial of said active material.
D'autres particularités et avantages de l'invention apparaítront dans la description détaillée ci-après.Other features and advantages of the invention will appear in the detailed description below.

5 montés chacun sur un support 6. Chaque
support 6 est monté de façon mobile par rapport au
corps 7 du projectile 1. Le projectile comporte en
outre des moyens pour faire passer chaque sous-ensemble
5 d'une position rentrée à l'intérieur du projectile 1
à une position déployée par rapport au corps 7 du
projectile. Les positions déployées respectives des
divers sous-ensembles 5 sont prédéterminées de façon
telle que lors de l'explosion de la charge explosive 2,
la matière active 4 contenue dans les divers sous-ensembles
5 est projetée sensiblement dans une même
direction.According to the invention, the

Dans l'exemple représenté, chaque sous-ensemble
5 est réalisé sensiblement sous la forme d'un
secteur cylindrique monté de manière pivotante autour
d'un axe 9 par rapport au corps 7 du projectile 1, de
façon à pivoter radialement vers l'extérieur par
rapport au corps 7 du projectile 1. In the example shown, each

forme de secteurs cylindriques sont identiques, sont
répartis régulièrement autour de l'axe 8 du projectile
1, et sont adaptés à pivoter d'environ 90 degrés par
rapport au corps 7. On a représenté aux figures quatre
secteurs disposés à 90 degrés l'un par rapport à
l'autre et s'étendant angulairement suivant un angle de
90 degrés environ.In this example, the
Comme représenté en particulier aux figures
2, 3 et 4, chaque sous-ensemble 5 est constitué d'un
support 6 formant paroi de base, d'un moyen d'amorçage
3, de matière explosive 2 et de matière active 4.As shown in particular in the figures
2, 3 and 4, each
Le support 6, par exemple en matériau
thermoplastique, est constitué de deux parois latérales
11,12 dirigées sensiblement radialement lorsque le
sous-ensemble 5 est dans sa position repliée à
l'intérieur du corps 7. Les deux parois latérales 11 et
12 sont séparées par un secteur de paroi cylindrique
intérieur 13. Le support 6 est limité à ses extrémités
axiales avant et arrière par des parois d'extrémité
14,15 sensiblement en forme de secteurs circulaires. Le
support 6 a ainsi une forme générale de cuvette.
Chaque sous-ensemble 5 comporte, dans sa
partie concave, un explosif 2, un moyen d'amorçage 3 de
l'explosif 2, et une matière active 4 disposée
radialement à l'extérieur de l'explosif 2 lorsque le
sous-ensemble est dans sa position repliée de la figure
3.Each
L'explosif 2 est par exemple un explosif comprimé, qui peut être de l'octoviton ou de l'hexocire. Explosive 2 is for example an explosive tablet, which may be octoviton or hexocire.
Le moyen d'amorçage 3 peut être un cordeau détonant.The priming means 3 can be a cord explosive.
La matière active 4 peut être une matière
génératrice d'éclats, une matière incendiaire, ou une
matière fumigène. Dans le présent exemple, on a
représenté une matière génératrice d'éclats, connue en
elle-même, par exemple un revêtement métallique
préfragmenté ou une matrice organique chargée de
billes, qui constitue la paroi extérieure 4 en forme de
secteur cylindrique de chaque sous-ensemble 5.The
Dans l'exemple représenté aux figures 1 à 4,
les sous-ensembles 5 sont articulés sur le corps 7 du
projectile 1 à leur extrémité arrière 5a par rapport au
sens 10 de déplacement du projectile 1. Ainsi, après
une rotation d'environ 90 degrés, les sous-ensembles 5
se retrouvent dans la position déployée représentée aux
figures 2 et 4, les supports 6 étant dirigés
sensiblement radialement. Dans cette position, la
détonation de l'explosif 2 projette les éclats dans la
direction opposée au support 6, perpendiculairement à
celui-ci, c'est-à-dire dans le sens de la flèche 16 qui
est opposé au sens de la flèche 10. Compte tenu d'une
certaine dispersion des éclats par rapport au sens des
flèches 16, on peut penser, en fonction de l'objectif
visé, à se limiter à cette dispersion ou à prévoir une
gerbe d'éclats plus dispersée en faisant pivoter les
sous-ensembles 5 d'un angle inférieur à 90 degrés qui
ferait que les flèches 16 seraient orientées à la fois
vers l'arrière du projectile et vers l'extérieur.In the example shown in Figures 1 to 4,
the
A cet effet, le projectile explosif 1
comporte des moyens pour régler l'angle maximum de
pivotement des divers sous-ensembles 5. Ces moyens, non
représentés, sont des moyens classiques, par exemple
des butées, qui peuvent être réglées par l'utilisateur
avant le départ du projectile 1. For this purpose, the explosive projectile 1
includes means for adjusting the maximum angle of
pivoting of the

programmable 17 qui commande de façon classique la mise

connus en eux-mêmes, pour commander ou interdire le
déploiement des divers sous-ensembles 5. Cette fusée 17
peut être programmée avant le tir ou sur trajectoire.
On comprendra qu'il est également possible de ne pas
commander le déploiement des sous-ensembles. Dans ces
conditions, la mise à feu de la charge explosive de
chaque sous-ensemble 5 projette les différents éclats
sensiblement radialement, et le projectile explosif se
comporte comme un projectile classique en projetant une
gerbe latérale d'éclats, comme schématisé à la figure
5. Dans ce cas, seule la partie de la gerbe d'éclats
comprise dans le secteur angulaire défini par la flèche
25 constitue la partie de cette gerbe utile contre la
cible 19.Projectile 1 includes a rocket
programmable 17 which conventionally controls the setting
with explosive charges. This
Au contraire, lorsque les sous-ensembles 5
sont déployés, le projectile explosif génère une gerbe
frontale arrière concentrée sur la cible 19, comme
schématisé à la figure 6.On the contrary, when the
On comprendra qu'il est également possible de
faire pivoter les sous-ensembles 5 par rapport à un axe
situé au niveau de leur extrémité axiale avant 5b (voir
figure 4), de façon à provoquer lors de la détonation
une gerbe frontale dirigée vers l'avant du projectile.It will be understood that it is also possible to
rotate the
Dans l'exemple représenté aux figures 1 à 4,
le corps 7 du projectile 1 comprend une arête centrale
20 qui supporte les axes de pivotement 9 et les
différents sous-ensembles 5 dans leur position rentrée.
Des flasques 21 sont solidaires de l'arête 20 et ont
pour fonction de rigidifier la structure du corps 7 et
éventuellement d'héberger des ailettes de stabilisation
22 déployables radialement dans le cas particulier
représenté d'un projectile stabilisé par empennage
(voir figures 1 et 2).In the example shown in Figures 1 to 4,
the
Le déploiement des sous-ensembles 5 peut être
déclenché par un moyen pyrotechnique quelconque
générateur de gaz schématisé en 23, ou par un système
mécanique à ressort ou équivalent. Dans le cas
représenté de sous-ensembles 5 articulés à leur
extrémité arrière, on comprendra que les efforts
aérodynamiques s'exerçant sur les sous-ensembles 5
ayant commencé à se déployer agissent sur ces sous-ensembles
pour les obliger à se déployer totalement.The deployment of the
Bien entendu, la présente invention n'est pas limitée au mode de réalisation que l'on vient de décrite, et on peut effectuer sur celui-ci de nombreux changements et modifications sans sortir du domaine de l'invention.Of course, the present invention is not limited to the embodiment which we have just described, and there are many changes and modifications without departing from the scope of the invention.
Ainsi, le projectile pourrait comporter deux sous-ensembles de forme sensiblement semi-cylindrique articulés selon des axes de pivotement parallèles à l'axe du projectile et voisins l'un de l'autre pour se déployer circonférenciellement dans deux sens opposés de façon à pouvoir projeter la matière active dans une direction radiale, sensiblement horizontale.So the projectile could have two sub-assemblies of substantially semi-cylindrical shape articulated along pivot axes parallel to the axis of the projectile and neighbors of each other to get deploy circumferentially in two opposite directions so as to be able to project the active ingredient into a radial direction, substantially horizontal.
De façon plus générale, les sous-ensembles pourraient être montés sur des supports mobiles radialement par rapport à l'axe du projectile de façon à se déployer radialement afin de projeter la matière active sensiblement axialement. Dans ce mode de réalisation comme dans les autres modes de réalisation précités, la charge utile du projectile en explosif et en matière active est essentiellement fonction de la longueur du projectile et non pas simplement de son calibre.More generally, the subsets could be mounted on mobile stands radially with respect to the axis of the projectile so to deploy radially in order to project the material substantially axially active. In this mode of realization as in the other embodiments mentioned above, the payload of the explosive projectile and in active matter is essentially a function of the length of the projectile and not just of its caliber.
On pourrait également combiner les modes de réalisation précités, et prévoir par exemple, sur quatre secteurs cylindriques, deux secteurs articulés à leur extrémité arrière et deux secteurs articulés à leur extrémité avant.We could also combine the modes of aforementioned realization, and provide for example, on four cylindrical sectors, two articulated sectors their rear end and two sectors hinged at their front end.
