- FIG. 5 shows a schematic view in longitudinal axial section of a projectile according to the present invention, during its implementation after impact
- FIGS. GA, 613, 6C and 6D schematically represent four successive stages in the use of the munition in accordance with the present invention
- FIGS. 7, 8 and 9 illustrate a projectile in accordance with variants of the invention, respectively, for FIG. 7, in longitudinal section, for FIG. 8, in external lateral view, and for FIG. 9, in longitudinal section after operation.
- the ammunition 10 according to the present invention shown in these appended figures essentially comprises a shell 50 which houses a projectile 100. Originally, that is to say during storage, the ammunition 10, formed of the shell 50 and the projectile 100, is centered on a longitudinal axis 12.
- the socket 50 essentially comprises a flared base 52 extended on the front by a cylindrical skirt 60 centered on the axis 12.
- the base 52 houses means for ejecting / propelling the projectile 100.
- ejection / propulsion means are formed for example and without limitation of a primer 54 associated with a pyrotechnic charge 56 forming propellant gas generator, opening into the internal chamber 62 of the socket 60, that is to say on the rear of the projectile 100.
- the sleeve 50 can be formed of a launcher tube.
- This projectile 100 essentially comprises a body 110, a slide 120, a container 130 of propellant under pressure and incapacitating agent and a warhead 140 associated with a striker 150.
- the body 1 10 preferably has a cylindrical envelope complementary to the internal chamber 62 of the sleeve 60.
- the body 1 10 preferably has on its rear end stabilization means 1 12, for example in the form of a skirt 1 13, possibly provided with perforations or through holes, increasing the effect of stability, even fins.
- the skirt 1 13 can be flexible to expand at the outlet of the launcher to define a stabilization drag.
- the body 1 10 is provided with a transverse partition 1 14.
- the slide 120 and the container 130 are placed in the chamber 1 16 of the body 1 10 located in front of the transverse partition 1 14.
- the warhead 140 is fixed to the front end of the body 1 10.
- the warhead 140 thus blocks the mouth of the chamber 1 16 formed in the body 1 10.
- the warhead 140 is preferably made from rubber and has a convex hemispherical envelope.
- the striker 150 is located on the internal face of the warhead 140.
- the striker 150 can be formed for example of a dome 152 provided with a central point 154 whose tapered end is directed towards the rear, ie towards the front end of container 130.
- the slide 120 is placed between the transverse partition 1 14 and the striker 154.
- the slide 120 is guided by sliding inside the chamber 1 16 of the body 110, along the axis 12.
- the container 130 is itself placed on the slide 120, that is to say between the bottom of the slide 120 adjacent to the transverse partition 1 14 and the striker 154.
- the container 130 houses an incapacitating agent and a propellant gas under pressure. It is preferably an aerosol reserve and a pressurized gas serving as propellant for this aerosol after rupture of the container 130.
- a spring 160 such as a helical spring is placed between the front end of the container 130 and the striker 154.
- safety means are provided which prevent the movement of the slide 120 , and consequently of the container 130, in approach of the striker 154 before the body 110 leaves the socket 60.
- Such security means can be the subject of different embodiments.
- these safety means comprise at least one tongue 1 18 coming from the body 1 10 and elastically deformed towards the interior of the chamber 1 16 when the projectile 100 is placed in the case 60 , to serve as a stop for the slide 120.
- the tongue 118 releases the slide 120 and consequently the container 130.
- tongues 1 1 8 are provided which are equally distributed around the axis 12.
- each tongue 1 18 is formed of a blade connected to the body 1 10 by its most front end 1 19, a protrusion 1 17 being provided on the outer face and on the rear end of the tongue 1 18.
- the tab or tabs block (s) the slide 120 and the container 130 away from the striker 154.
- the external support to the protuberance 1 17, previously formed by the sleeve 60 is eliminated.
- the tongue 1 18 can then resiliently return to its rest position in alignment with the thickness of the wall of the body 1 10 ( Figures 3 and 6B).
- the slide 120 is capable of displacement along the axis 12 in the body 110. The projectile 100 is therefore armed.
- the spring 160 prohibits any untimely movement of the slider 120 and of the container 130 when approaching the striker 154.
- the range and speed of the projectile 100 defined by the power of the propulsion means 54 and 56 are adapted to avoid any injury to an individual I targeted by the projectile 100.
- the resulting deceleration of the projectile 100 causes rapid movement of the slide 120 and of the container 130 towards the front, ie against the striker 154, by compression of the spring 160.
- the front end of the container 130 is struck by the striker 154, the container 130 is perforated.
- the incapacitating agent for example in the form of an aerosol, contained in the container 130 can then be released and diffused under the effect of the propellant gas stored under pressure in the container 130 (FIG. 4).
- This diffusion of the incapacitating agent can be made effective if, as illustrated in FIG. 5, the spring 160 subsequently causes the slide 120 and the container 130 to retreat away from the striker 154 to release the perforation produced in the wall of the container 130 by this striker 154.
- the incapacitating agent placed in the container 130 is diffused on the outside through at least one orifice 170 formed in the wall of the body 110, in the vicinity of its front end.
- FIGS. 5 and 6D there are preferably provided several orifices 170 equi-distributed around the axis 12 on the front end of the body 110, either immediately behind the warhead 140.
- This arrangement allows an omni-directional diffusion of the active agent contained in the projectile.
- the present invention is not limited to the diffusion of a particular active agent. If it preferably relates to the diffusion of an incapacitating agent, it also applies to the diffusion of active agents of different nature, such as for example a paint, or even a combination of several active agents.
- the active agent can be in many forms, among which there may be mentioned without being limiting: powders, in particular powders in a solvent, fumigants and aerosols.
- the active agent can be stored in the same container as the propellant under pressure or in a chamber separate from it before impact.
- the pressurized gas can be permanently stored in the container 130 of the projectile or else stored in the container 130 when the projectile 100 is expelled, by transferring part of the gases. generated by the means 54 and 56 in the container 130, by means of a valve provided for this purpose in the rear part of the container 130.
- the gas ensuring the diffusion of the active agent can be generated by pyrotechnic means initiated during the impact on the striker 154.
- a non-lethal ammunition comprising a body 1 10 which houses a container 130 capable of generating a gas under pressure and a warhead 140 associated with a striker 154 capable of allowing the diffusion of an active agent during an impact.
- the projectile illustrated in FIGS. 7 to 9 is characterized by the presence of means making it possible to ensure its self-destruction, in the event of a malfunction.
- these self-destruct means are preferably formed of a pyrotechnic delay 200 located in the base 52 of the projectile.
- the delay 200 is adapted to be initiated at the start of the projectile.
- the projectile illustrated in FIGS. 7 to 9 comprises an improved warhead 140, in the form of a hemispherical cap, made of silicone, preferably, with shoreA hardness between 10 and 30, very preferably between 12 and 15.
- the projectile illustrated in FIGS. 7 to 9 is characterized by a deformable structure 210 adjacent to the warhead 140.
- this deformable structure 210 can be the subject of numerous alternative embodiments. According to the particular embodiment illustrated in FIG. 8, this deformable structure 210 consists of the front part of the body 110, in the form of a thin metallic envelope, for example with a thickness of 0.1 to 0.5 mm, possibly pre-embrittled, for example in the form of markings longitudinal 212 distributed over the periphery of the body 110.
- FIG. 9 illustrates the state of the projectile after operation, that is to say after percussion of the container 130, by deformation of the structure 210.
- the variant of FIG. 9 is devoid of delay 200.
- the deformable structure 210 can be the subject of numerous variant embodiments, for example in the form of deformable dampers. According to a specific embodiment, it may be a shock absorber with plastic deformation at the head of the projectile produced in the form of an aluminum tube adapted to collapse on itself by absorbing a section of the kinetic energy and transform it into plastic deformation energy upon impact.
- the slide can be formed by the case itself of the container 130 (or as a variant the support body itself of the striker 154).
- the striker is fixed and the container capable of displacement.
- the reverse arrangement can be provided, that is to say that the container can be fixed and the striker mobile during impact.
