Definitions

  • This invention relates to less lethal weapon projectiles, able to impact a target such as would a violent stroke of the fist while limiting the damage and or the traumas induced by this impact, in particular on the sensitive and unprotected zones of an individual (in particular the head).
  • LLW projectiles for Less Lethal Weapon
  • LLW projectiles are conventionally used by law enforcement and the armed forces in exterior operations, with the purpose of neutralizing or to cause to flee certain individuals, avoiding injuring them or minimizing the injuries or lesions incurred.
  • these LLW projectiles have an overall cylindrical shape of which the length is of a magnitude of 50 to 70 mm and of which the diameter, as specified previously, is of a magnitude of 40 mm, with a front end in the shape of an overall demi-spherical cap. They are conventionally carried out by molding thermoplastic foam.
  • the physical parameter that is important at the impact from the point of view of lesion effects is the force at impact exerted on the target.
  • the main objective of the invention is to transmit to the impact a programmed force which is always the same, or substantially the same, regardless of the terminal speed, and correlatively regardless of the firing distance (and this within the conventional ranges of speed at the time of impact (i.e. about between 50 to 100 m/s).
  • the LLW projectile according to the invention which has an overall cylindrical shape of longitudinal axis L, comprising a front end in the shape of a spherical or approximately spherical cap and a rear end, is characterized by the fact that it comprises:
  • the base of the projectile is deformed during the firing by the scratches of the tube of the weapon which allows for the putting into rotation of the projectile.
  • the core made of aluminum foam is very light and it offers the characteristics of crushing and of absorbing energy that are very interesting, homogeneous and independent of the speed of deformation in all directions; the outer case makes it possible to optimize the ballistic flight of the projectile and to lessen at the moment of impact the first projectile-target contact.
  • the force of impact of this projectile is constant or almost constant regardless of its speed (in the conventional ranges of impact speed, in particular between 50 and 100 m/s).
  • This impact force is in particular according to the density of the aluminum foam, a parameter chosen according to the force of impact sought.
  • the density of the aluminum foam used for the core of the LLW projectile in accordance with the invention is between 30 and 300 kg/m 3 .

  • the transversal wall of the base is extended towards the front by a tubular extension, centered on the longitudinal axis L, in order to form a housing for the reception of the rear end of the core made of aluminum foam.
  • said rear tubular wall, or said front tubular extension comprises an annular exterior ring for guidance.
  • the transversal wall of the base is extended towards the front by an axial tenon allowing for the centering of the front portion of the projectile.
  • the outer case extends to the rear base to cover the entire exposed face of the core.
  • the rear end of the outer case comprises a bead, directed inwards, which penetrates into an annular receiving groove arranged in the core made of aluminum foam.
  • the front end of the base advantageously covers the rear end of the outer case, in order to lock into position said bead in the receiving groove.
  • the front end of the base and the rear end of the outer case cooperate more preferably through complementary shoulders.
  • the core can comprise an axial recess opening into its rear face facing the front transversal wall of the base.
  • This recess makes it possible in particular to program two levels of impact force by selecting two densities of aluminum foam. It can remain as is or be filled by a more or less dense aluminum foam, in order to program the severity of the impact.
  • the projectile comprises an annular contraction between its front and rear ends, corresponding to a decrease in diameter, said contraction extends towards the front starting from the front end of the base.
  • This particularity has in particular for objective to prevent the contact of the base as an inclined impact with the target.
  • the projectile in accordance with the invention can comprise a structure made of a reversible deformation material, inserted in the front, on the axis L, between the outer case and the core.
  • This material can be a thermoplastic foam or be comprised of microbeads.
  • the base, the core and the outer case of the projectile are carried out independently and they are assembled together by any suitable means.

  • an aluminum foam is used manufactured by the company CYMAT Corporation (Canada) under the designation “Cymat stabilized aluminum foam” (registered trademark), or by the company SHINKO WIRE CO Ltd (Japan), under the designation “Alporas” (registered trademark).
  • Such a core structure 6 has for function to limit at the impact the impact force predetermined beforehand during the absorption of the energy, regardless of the impact speed of the projectile.
  • the shape at the front of this honeycombed structure in addition makes it possible to retain the time for coming to force of the impact, until nominal level, below the critical burst value of the scalp for example.
  • the rear end 13 of the core 6 is assembled with the front end 11 , 12 of the base 5 by any suitable means, for example by gluing.

  • This case 7 is the shape of a tube closed at its front end by a spherical or substantially spherical cap, is fixed onto the core 6 by any suitable means, for example by gluing.
  • the case 7 has for function to improve the ballistic flight of the projectile, prevent at the first target-projectile contact the local bursting of the biological material of the target and allow for the pre-crushing of the honeycombed structure of aluminum.
  • FIG. 3 shows an alternative embodiment of the projectile of the FIGS. 1 and 2 .
  • the portions that are identical to the preceding embodiment retain the same marks in order to facilitate comprehension.
  • the core 6 comprises a blind axial recess 20 that opens into its rear face 14 .
  • This recess 20 advantageously has a cylindrical shape of which the diameter corresponds, to the nearest clearance, to that of the axial tenon 12 of the base 5 . Its function is to make it possible to carry out during the impact an impact force profile at two levels programmed beforehand, according to the severity sought.
  • the recess 20 can be filled with an added material.
  • This added material can for example consist of an aluminum foam that is denser than that used for the periphery of the core 6 , in such a way as to increase the effectiveness of the impact of the projectile.

  • FIGS. 4 and 5 are also distinguished from the preceding ones, by the presence of a contraction 23 , corresponding to a reduction in diameter, between is rear 2 and front 4 ends.
  • This contraction 23 has for function to prevent, as an inclined impact of the projectile, the plastic base-target contact, preventing as such a level of contact impact that is incompatible with the programming of the efforts by the aluminum foam.
  • the presence of the contraction 23 confers upon the core 6 a particular longitudinal section, with a rear end 13 of cylindrical shape extended by a front end 16 in the shape of a bead or bulge, of an overall spherical shape.

  • This particular shape of the front end 4 of the projectile 1 ′′ makes it possible to calibrate the rate of the increase in effort (level of the force programmed over the time taken to reach it), thus preventing the local bursting of the biological structures (scalp for example as a cranial impact).
  • FIG. 6 is a curve showing the variation of the force during the impact according to the impact time, for the projectiles 1 and 1 ′′ of FIGS. 1 and 2 , on the one hand, and 4 and 5 on the other hand.
