Definitions

  • the present invention relates to a projectile for non-lethal ammunition, used in a fire arm.
  • Non-lethal arms are designed and employed to incapacitate people and material temporarily, without causing deaths, permanent injuries or even undesirable material damages to buildings and to the environment. Thus, they enable one to employ gradual force, reducing the situations in which the use of lethal arms is determinant.
  • Non-lethal arms further have a broad application in the public-security area, especially in controlling disturbances of all kinds, including in the case of injuries in the prison system.
  • non-lethal arms As non-lethal arms, one can exemplify truncheon, chemical-product sprayers, electric-shock devices, miscellaneous-effects grenades and non-lethal ammunition launchers, among which rubber bullets.
  • Rubber bullets are usually inserted into cartridges, the basic function of which is similar to that of an ordinary cartridge. Its action, however, when they are shot against a person, aims at incapacitating him temporarily without causing death or permanent damage.
  • non-lethal may be a cartridge comprising a plurality of rubber spheres, as is the case of the Model 3020 Stinger-HV cartridge from Armor Holdings, which has 18 spheres, shown in FIG. 1 .
  • This type of ammunition has the same functioning principles of a conventional lethal ammunition.
  • Such conventional lethal ammunition comprises a priming cap A, which ignites a projection charge B that accounts for driving the projectile(s) C.
  • the possibility of one of the projectiles hitting the target is greater than if a single rubber sphere were used.
  • the accuracy of the shooter decreases considerably, since the dispersion of the projectiles along the path renders it difficult to determine the impacts points.
  • Non-lethal ammunition employs a smaller amount of projectiles, such as AM403/A or AM-403C from Condor Tecnologias Näo-Letais, which have 3 projectiles (see FIGS. 2 and 3 ).
  • projectiles such as AM403/A or AM-403C from Condor Tecnologias Näo-Letais, which have 3 projectiles (see FIGS. 2 and 3 ).
  • These ammunitions have the same functioning principle of the ammunition mentioned before, but these ammunitions have 3 cylinders or spheres D inserted in one cartridge E, which are the projectiles of this ammunition.
  • These projectiles, made from rubber, are sequentially arranged within the cartridge E and do not have a satisfactory accuracy, as the earlier projectiles did.
  • the shooting should be effected at a minimum safety distance, so that the projectile will slow down sufficiently before hitting the target.
  • the single projectile type is similar to those mentioned before, but instead of having a plurality of projectiles, it has only one cylindrical projectile.
  • This type of projectile is shown in FIG. 4 , which discloses an ammunition F with a single cylindrical projectile G.
  • this projectile comes out of the firearm it has greater accuracy that those with a larger number of projectiles, since its stability can be maximized while it runs through the barrel.
  • the accuracy is higher, the flight of this projectile is still not stable. So, the shooter is liable to hit undesired points at the target person or simply miss the desired target, even if he has used the triggering equipment correctly.
  • bean-bag Another type of single projectile, known as “bean-bag”, consists of a bag sewn at the edges and filled up with some material allowing the bag to be folded within a cartridge, as can be seen in FIG. 5 . After the triggering, the “bean-bag” passes through the barrel and, upon coming out of it, opens up due to pressures that the air exerts on this “been-bag”. Since the shape and the position of the bean-bag may be little determined during its flight, its path is easily modified because the lack of aerodynamics of such “bean-bag”. Moreover, the material used for filling up the bean-bag is often composed of small lead spheres prone to polluting the environment and that may be lethal, in case the bag in which they are contained breaks open.
  • a flight-stability device J has been developed, which can be seen in FIG. 6 .
  • This flight-stability device J is a kind of tail fixed to the “bean-bag” so that this tail will create a drag at a back portion of the bean-bag and thus impart greater stability to the flight of this projectile.
  • An example of a bean-bag provided with the flight-stability device J, for stability after triggering an arm with this type of ammunition, is shown in FIG. 7 .
  • the accuracy of this projectile is not satisfactory so as to provide sufficient safety for the use of the non-lethal ammunition.
  • the ammunition of the type of a projectile having rubber wings has the shape shown in FIG. 8 .
  • This shape theoretically ensures a relatively foreseeable flight of the projectile, since at the back portion of the projectile there are flaps L that impart greater stability to it.
  • flaps L that impart greater stability to it.
  • it is essential for this type of ammunition to be made of a soft material in order to guarantee its non-lethality, the high pressures which the projectile undergoes during its flight cause deformations on these flaps and impair the foreseeability of the projectile path, causing the accuracy not to be satisfactory for the required safety standards.
  • An objective of the present invention is to provide a projectile for non-lethal ammunition having a safe accuracy.
  • the projectile is a body having a first portion and a second portion, which have different masses to increase the precision of the weapon that uses the present projectile. Between these portions, there is a strangulation that unites them, the first portion being composed of a plurality of rings connected by annular grooves, as well as an annular base at an end opposite the first portion, which increases the flight stability of the projectile.

  • FIG. 13 is an illustration of the accuracy achieved by the non-lethal ammunition provided with the non-lethal projectile shown in FIG. 10 .
  • FIG. 9 weapons provided with a non-lethal ammunition may be used against people.
  • the figure shows a demonstration of the use of the present invention.
  • a shooter armed with a firearm shoots from a minimum distance of 20 meters at people. This distance varies according to the recommendations of each manufacturer of the non-lethal ammunition, and should be sufficient for the non-lethal projectile to decelerate sufficiently, so that, upon hitting the person, its effect will not be lethal or does not cause permanent traumas on the target person.
  • the shooter shown in FIG. 9 makes adequate use of the weapon, since he aims regions, in this case the legs, of the target person where the possibility of causing a permanent trauma is completely eliminated.
  • the main objective of the present invention is to increase the accuracy of non-lethal projects, since it guarantees sufficient precision for the shooter to hit the desired target at adequate shooting distances against target people.
  • the desired target may be not only a person, but also an object; for instance, if the shooter desires to hit the arm held by an aggressor without impairing the safety of third people around. Since it is highly desirable to increase the precision of the non-lethal ammunitions, the projectile of the present invention meets the present demand for precision in triggering arms with the objective of non-lethality.
  • FIG. 10 shows a cross-sectional view of a projectile 1 for a non-lethal ammunition, composed of a first portion 2 , which comprises three coaxial and equidistant rings 3 .
  • the rings 3 are spaced apart by two annular grooves 6 , arranged between the rings 3 , which in reality are a reduction of the diameter in the intersection of the rings 3 .
  • the form between the rings 3 and the annular grooves 6 are essential for absorbing kinetic energy during the impact of the projectile 1 against the target, since some of the kinetic energy is lost in the form of deformation work, because upon the impact with the target the rings are compressed against themselves so as to act as a damper during the impact. Further, the annular grooves 6 aid in deforming the first section 2 .
  • the first portion 2 is also used for aiding in the stabilization of the projectile during its flight, since the first portion 2 has the biggest part of the mass of the projectile 1 .
  • the mass center is located closer to one of the ends of the projectile 1 , which in the present embodiment of the invention, is on the first portion 2 .
  • Such a distribution of mass makes the mass center of the projectile 1 as front as possible (with respect to the path direction) to the aerodynamic center of the projectile 1 , thus increasing the stabilizing moment.
  • the fact of increasing the stabilizing moment of the projectile 1 in conjunction with other characteristics of the projectile 1 , which will be explained later, makes the flight stable, so that the required accuracy is achieved.
  • a second portion 4 which is a “skirt” of the projectile 1 .
  • This second portion 4 communicates with the first portion 2 by means of a strangulation 5 , which has a diameter smaller than that of the rings 3 . From the strangulation 5 towards the first portion 2 , the diameter of the second portion 4 increases gradually until it reaches the shoulder 8 . From this shoulder 8 , an annular base 7 stretches, which has a diameter slightly larger than the diameter of the rings 3 . Moreover, an internal region 9 of the second portion 4 is hollow, so as to reduce the mass of the second portion 4 and not to impair the position of the mass center, which influences the behavior of the projectile 1 greatly during its flight.
  • the above-described shape of the second portion 4 is essential for the stabilization of the project 1 during its flight and in the arm barrel, where the pressures are high.
  • the annular base 7 has a larger diameter than any other part of the projectile 1 . In this way, when the ammunition is fired, the annular base comes in friction contact with the arm barrel, thus effecting the initial deceleration of the projectile, and further, with this friction contact, a stabilization of the projectile within the barrel takes place, which renders the projectile 1 stable while it is coming out and starting a stable flight until the target is hit.
  • the most suitable material for the manufacture of the projectile 1 is rubber.
  • the projectile is made by rubber injection.
  • other material may be employed for making it.
  • this manufacture is effected by injection, all of the components of the projectile 1 described above constitute a single piece.
  • the second portion 4 In spite of the increase obtained in accuracy of the projectile 1 described above, one has also made an improvement in the second portion 4 , namely the introduction of a core 10 within the region 9 .
  • This core 10 can be seen in FIG. 11 , which is an internal reinforcement of the second portion 4 , so as to impart more mechanical strength.
  • the thickness of the bore wall 10 is as small as possible in order not to increase too much the mass of the second portion 4 , so that it will not influence the mass center of the projectile 1 and the external shape of the bore 10 fits into the internal shape of the second portion 4 , that is, of the region 9 .
  • the material used for the bore 10 is plastic, but one should understand that the bore 10 is made of a material that simply increases the mechanical strength of the second portion 4 , and there is the possibility of applying other treatments and devices for obtaining the desired strength.
  • the achievement of the above-mentioned strength is due to the fact that, during the expansion of the gases from the gunpowder combustion of the ammunition, the back portion 4 undergoes high pressures, so as to impair the desired shape of this part. If the shape changes significantly within the barrel or even during the flight of the projectile, the stability is strongly impaired, for which reason the above-mentioned reinforcement has been introduced.
  • FIG. 12 one can se the arrangement of the projectile 1 inside the cartridge 11 . It must be noted that the projectile 1 is totally inserted into the cartridge 11 , but the projectile 1 may be used in the most varied types of ammunition.
  • FIG. 13 which illustrates the demonstration of ballistic tests, that the triggering is effected from a 20-meter distance at a standard target having a 20-centimeter diameter.
  • the present projectile 1 indeed exhibits accuracy much superior to that of the prior-art projectiles.
