Abstract

The invention relates to a cartridge for disseminating electromagnetic chaff which can be fired by means of a pistol. Inside a caseholder is mounted a projectile (10). This contains shells (20, 25 and 30), each consisting of a circular bottom integral with at least one half-cylinder of the same diameter. These shells interact there to define two receptacles for electromagnetic chaff. The electromagnetic chaff is advantageously selected to reflect two different wavelength ranges. The projectile of a calibre of 40 mm makes it possible to launch at 80 metres a large-size cloud of electromagnetic chaff. The invention is used particularly as an ocean alarm cartridge. <IMAGE>

Description

L'invention concerne une cartouche de lancement de leurres électromagnétiques, qui conviennent particulièrement comme moyen d'alarme.The invention relates to a cartridge for launching electromagnetic decoys, which are particularly suitable as an alarm means.

On connaît déjà des pistolets d'alarme, qui tirent des cartouches ou fusées luminescentes. Quoique ces pistolets d'alarme aient rendu et rendent encore de grands services, ils ne donnent pas entière satisfaction dans certains cas, notamment celui des recherches en mer. En effet, de telles recherches font intervenir des avions qui quadrillent la zone où l'on peut espérer retrouver le ou les navigateurs à la dérive. A bord de ces avions, des observateurs cherchent à repérer visuellement l'ambarcation à la dérive, ou des signaux de détresse émis par leurs occupants. Ces recherches purement visuelles sont évidemment rendues très difficiles par temps nuageux , et les pistolets lance-fusée et autres dispositifs fumigènes ne sont pas d'un grand secours, surtout de jour.Alarm pistols are already known, which fire luminescent cartridges or rockets. Although these alarm pistols have rendered and still render great services, they are not entirely satisfactory in certain cases, in particular that of searches at sea. Indeed, such searches involve planes which crisscross the area where one can hope to find the drifting navigator (s). On board these planes, observers seek to visually locate the drifting boat, or distress signals emitted by their occupants. These purely visual searches are obviously made very difficult in cloudy weather, and rocket launchers and other smoke devices are not of much help, especially during the day.

La présente invention a pour but principal de fournir une cartouche qui puisse être tirée par un simple pistolet, et soit beaucoup plus facilement répé- rable pour les avions, à l'aide du radar de bord de ceux- ci.The main object of the present invention is to provide a cartridge which can be fired by a simple pistol, and which is much more easily identifiable for airplanes, using the onboard radar thereof.

Cette cartouche comprend classiquement un projectile dans une douille-étui, munie d'une amorce et d'une charge d'éjection.This cartridge conventionally comprises a projectile in a casing case, provided with a primer and an ejection charge.

Selon une première caractéristique de l'invention, le projectile est équipé d'une charge de dépotage allumée par l'intermédiaire d'un retard de dépotage par la charge d'éjection, et ce projectile renferme des leurres électromagnétiques.According to a first characteristic of the invention, the projectile is equipped with an unloading charge lit by means of an unloading delay by the ejection charge, and this projectile contains electromagnetic decoys.

Très avantageusement, les logements de leurres électromagnétiques sont délimités par des coquilles, définies chacune par un fond circulaire, sur lequel s'appui au moins un demi-cylindre. Par coopération de deux coquilles de ce genre, on définit un logement cylindrique pour une charge de leurres.Very advantageously, the housings of electromagnetic decoys are delimited by shells, each defined by a circular bottom, on which rests at least a half-cylinder. By cooperation of two shells of this kind, a cylindrical housing is defined for a load of lures.

Ainsi, selon une caractéristique importante de l'invention, le projectile comporte un cylindre qui le délimite, et est muni d'un fond qui porte le retard de dépotage. Dans ce cylindre, une première coquille demi-cylindrique vient s'appliquer contre un fond circulaire épais, qui définit en partie basse un logement pour la charge de dépotage. Une deuxième coquille demi-cylindrique vient coopérer avec la première à l'intérieur du cylindre pour définir un premier logement cylindrique de leurres.Thus, according to an important characteristic of the invention, the projectile comprises a cylinder which delimits it, and is provided with a bottom which carries the depot delay. In this cylinder, a first semi-cylindrical shell is applied against a thick circular bottom, which defines in the lower part a housing for the discharge load. A second semi-cylindrical shell cooperates with the first inside the cylinder to define a first cylindrical housing for lures.

Cette deuxième coquille peut comporter un fond circulaire à sa base, ou bien un fond séparé peut être prévu pour fermer le logement de l'autre c8té du premier fond circulaire mentionné. Ce premier fond circulaire peut également être solidaire ou séparé de la première demi-coquille.This second shell may have a circular bottom at its base, or a separate bottom may be provided to close the housing on the other side of the first circular bottom mentioned. This first circular bottom can also be integral with or separated from the first half-shell.

Dans un mode de réalisation avantageux, le projectile comprend deux logements de leurres, et la deuxième coquille comprend non seulement un fond circulaire à sa base mais aussi un deuxième demi-cylindre qui s'étend de l'autre c8té du fond par rapport au premier demi-cylindre. Il s'y ajoute une troisième coquille, demi-cylindre, et un fond circulaire, séparé. ou non de la troisième coquille pour coopérer avec la deuxième coquille et définir un second logement de leurres. De la sorte, on peut placer dans le projectile deux charges de leurres différentes, susceptibles de former des échos significatifs dans les deux gammes de fréquence les plus utilisées par les radards de bord des aéronefs.In an advantageous embodiment, the projectile comprises two lure housings, and the second shell comprises not only a circular bottom at its base but also a second half-cylinder which extends from the other side of the bottom relative to the first half cylinder. There is a third shell, half-cylinder, and a separate circular bottom. or not from the third shell to cooperate with the second shell and define a second lure housing. In this way, it is possible to place in the projectile two charges of different decoys, capable of forming significant echoes in the two frequency ranges most used by on-board radars of aircraft.

Dans un mode de réalisation particulier, la cartouche est de calibre 40 mm, et est agencée pour tirer un nuage de leurres à une hauteur d'environ 80 mètres au dessus de la surface du sol ou de la surface de la mer.In a particular embodiment, the cartridge is 40 mm caliber, and is arranged to shoot a cloud of lures at a height of about 80 meters above the surface of the ground or the surface of the sea.

D'autres caractéristiques et avantages de l'invention apparaitront à la lecture de la description détaillée qui va suivre, faite en référence aux dessins annexés, donnés uniquement pour illustrer à titre non limitatif le mode de réalisation préférentiel de la présente invention, et sur lesquels :

  • - la figure 1 est une vue en coupe d'un mode de réalisation de la cartouche selon l'invention ;
  • - la figure 2 est une vue en perspective démontée illustrant l'emboîtement des coquilles définissant les logements de leurres dans ladite cartouche ; et
  • - la figure 3 est une vue en perspective démontée illustrant l'emboitement des coquilles définissant les logements de leurres, dans une variante de réalisation.
Other characteristics and advantages of the invention will appear on reading the detailed description which follows, given with reference to the appended drawings, given solely to illustrate, without limitation, the preferred embodiment of the present invention, and in which :
  • - Figure 1 is a sectional view of an embodiment of the cartridge according to the invention;
  • - Figure 2 is a disassembled perspective view illustrating the interlocking of the shells defining the lure housings in said cartridge; and
  • - Figure 3 is a disassembled perspective view illustrating the interlocking of the shells defining the lure housings, in an alternative embodiment.

La cartouche de la figure 1 comporte extérieurement une douille-étui 1, de forme cylindrique, complétée par un fond 2. Au centre de ce fond est classiquement montée une amorce 3.The cartridge of FIG. 1 externally comprises a sleeve-case 1, of cylindrical shape, supplemented by a bottom 2. In the center of this bottom is conventionally mounted a primer 3.

A l'intérieur de la douille et au voisinage immédiat du fond est placée en coopération avec l'amorce 3 une charge d'éjection 4, entourée d'un anneau cylindrique 5. L'extrémité libre de l'étui est fermée par un bouchon 6, retenu par clipsage d'un prolongement cylindrique mince 7 de la douille-étui 1.Inside the socket and in the immediate vicinity of the bottom is placed in cooperation with the primer 3 an ejection charge 4, surrounded by a cylindrical ring 5. The free end of the case is closed by a plug 6, retained by clipping a cylinder extension thin pin 7 of the holster 1.

Le projectile placé dans l'étui est défini par une enveloppe cylindrique emboutie 10, comportant latéralement une paroi cylindrique mince 11, associée à un fond 12. Au centre, ce fond constitue une protubérance 13 vers le bas, et cette protubérance 13 enferme à l'intérieur d'une frette 14 un retard de dépotage 15 qui vient coopérer avec la charge d'éjection 4 pour être allumé par celle-ci. Autour de la protubérance centrale 13 est placé un joint de feutre 16.The projectile placed in the case is defined by a stamped cylindrical envelope 10, laterally comprising a thin cylindrical wall 11, associated with a bottom 12. In the center, this bottom constitutes a protrusion 13 downwards, and this protuberance 13 encloses the 'Inside a hoop 14 an unloading delay 15 which cooperates with the ejection charge 4 to be lit by the latter. Around the central protrusion 13 is placed a felt seal 16.

Dans le projectile est placé une première coquille, désignée par la référence numérique 20, et comprenant un fond épais de forme générale circulaire 22, sur lequel vient s'appuyer un demi-cylindre 21 (voir figure 2). Le fond épais 22 comporte du côté opposé au demi-cylindre 21 une échancrure centrale en forme de disque 23, qui vient contenir la charge de dépotage du projectile.In the projectile is placed a first shell, designated by the reference numeral 20, and comprising a thick bottom of generally circular shape 22, on which rests a half-cylinder 21 (see FIG. 2). The thick bottom 22 has, on the side opposite to the half-cylinder 21, a central notch in the form of a disc 23, which contains the charge for stripping the projectile.

Comme le montrent les figures 1 et 2, une seconde coquille, désignée par la référence générale 25, comporte elle aussi un fond 26, avec un demi-cylindre 27 d'un côté de ce fond, et un autre demi-cylindre 28 de l'autre côté du fond 26. On voit que la première coquille 20 et la seconde coquille 25 viennent coopérer pour définir entre leurs fonds 22 et 26 et leurs demi-cylindres dres 21 et 27 un premier logement pour des leurres électromagnétiques 29.As shown in FIGS. 1 and 2, a second shell, designated by the general reference 25, also has a bottom 26, with a half-cylinder 27 on one side of this bottom, and another half-cylinder 28 of the on the other side of the bottom 26. It can be seen that the first shell 20 and the second shell 25 cooperate to define, between their bottoms 22 and 26 and their half-cylinders dres 21 and 27, a first housing for electromagnetic lures 29.

Dans un mode de réalisation avantageux, le projectile comporte encore une troisième coquille, désignée par la référence numérique générale 30, et constituée elle aussi comme le montrent les figures 1 et 2 d'un fond 31, sur lequel vient s'appuyer un demi-cylindre 32. Cette troisième coquille 30 vient à son tour coopérer avec la seconde coquille 25 ; les fonds 26 et 31, et les demi-cylindres 28 et 32 définissent un second logement pour un second ensemble de leurres électromagnétiques 33.In an advantageous embodiment, the projectile further comprises a third shell, designated by the general reference numeral 30, and also constituted, as shown in FIGS. 1 and 2, of a bottom 31, on which rests a half cylinder 32. This third shell 30 in turn cooperates with the second shell 25; the bottoms 26 and 31, and the half-cylinders 28 and 32 define a second housing for a second set of electromagnetic decoys 33.

Enfin, l'ensemble des coquilles ainsi placées à l'intérieur du projectile est maintenu par une lame de ressort 35, qui les tient en place à la fois pour constituer de manière stable les logements des leurres, et pour maintenir la charge de dépotage 23 en coopération étroite avec le retard de dépotage 15.Finally, all the shells thus placed inside the projectile are held by a spring leaf 35, which holds them in place both to form stably the housing for the lures, and to maintain the loading load 23 in close cooperation with the unloading delay 15.

Il s'est avéré préférable que les deux demi-cylindres incorporés à la deuxième coquille 25 soient placés symétriquement par rapport au centre du fond en forme de disque 26. On obtient ainsi, au dépotage, une meilleure répartition des leurres électromagnétiques dans l'air.It has been found preferable that the two half-cylinders incorporated in the second shell 25 are placed symmetrically with respect to the center of the disc-shaped bottom 26. In this way, a better distribution of the electromagnetic lures in the air is obtained. .

Dans une variante de réalisation représentée à la figure 3, les coquilles sont toujours constituées par des demi-cylindres, mais les fonds circulaires qui servent à les fermer sont des pièces séparées des demi-cylindres, et ces pièces viennent s'appuyer contre la base libre des demi-cylindres. Les références numériques sur la figure 3 désignent les mêmes pièces qu'à la figure 2.In an alternative embodiment represented in FIG. 3, the shells are always constituted by half-cylinders, but the circular bottoms which serve to close them are parts separated from the half-cylinders, and these parts come to bear against the base free of the half-cylinders. The numerical references in FIG. 3 designate the same parts as in FIG. 2.

Dans un mode de réalisation préférentiel, les deux paquets de leurres sont constitués d'une distribution de bâtonnets métallisés capables de former un obstacle aux ondes électromagnétiques dans des gammes de fréquence normalement utilisées pour les radars de recherche et de détection.In a preferred embodiment, the two packets of lures consist of a distribution of metallized rods capable of forming an obstacle to electromagnetic waves in frequency ranges normally used for research and detection radars.

Les essais effectués par la demanderesse ont montré que le lanceur de leurres ainsi obtenu pouvait facilement être tiré à une hauteur de 80 mètres environ au dessus des flots, et que le nuage de leurres ainsi constitué était très aisément repérable par tous les temps à l'aide du radar de bord des avions chargés de la recherche. Il apparait donc que la cartouche à leurres électromagnétiques de la présente invention constitue un moyen d'alarme extrêmement efficace et très facile à mettre en oeuvre. Incorporée aux trousses d'urgence, cette cartouche est de nature à permettre le sauvetage de vies humaines, tout particulièrement en mer.The tests carried out by the applicant have shown that the lure launcher thus obtained could easily be pulled to a height of about 80 meters above the waves, and that the cloud of lures thus formed was very easily locatable in all weathers. using on-board radar for research aircraft. It therefore appears that the cartridge electromagnetic decoys of the present invention constitutes an extremely effective alarm means and very easy to implement. Incorporated in emergency kits, this cartridge is capable of saving lives, especially at sea.
