Definitions

  • the invention relates to a cartridge for launching electromagnetic decoys, which are particularly suitable as an alarm means.
  • 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.
  • 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.
  • This cartridge conventionally comprises a projectile in a casing case, provided with a primer and an ejection charge.
  • 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.
  • the housings of electromagnetic decoys are delimited by shells, each defined by a circular bottom, on which rests at least a half-cylinder.
  • a cylindrical housing is defined for a load of lures.
  • the projectile comprises a cylinder which delimits it, and is provided with a bottom which carries the depot delay.
  • 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.
  • 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.
  • the projectile comprises two lure housings
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • a felt seal 16 Around the central protrusion 13 is placed a felt seal 16.
  • 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.
  • 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.
  • 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.
  • 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. .
  • 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.
  • 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.
  • 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.
