Definitions

  • Conventional anti-bullet defenses are based on common principles, essentially on the destruction, reduction or restriction of the ballistic capacity of projectiles, preventing, reducing or weakening their penetration in the defense and the access to the targets according to the above mentioned mechanic characteristics of the defenses (hardness, density, friction, etc.) of the materials used (in general, alloys, as the case might be, in combination with elastomers).
  • German patent No. 2,759,193 corresponds to a multilayer defense or antiballistic packet, which differs from the prior art in the combination of at least one layer formed of a plurality of small units made up of thin sheets of glass, ceramics and/or sintered hard metals, included in a matrix of nylon, synthetic resins, steel, etc.
  • said layer(s) is(are) combined with layers made of other materials, for example elastomers, or which include hollow tubular or round bodies made of sintered steel or ceramics.
  • EP 0,041,271 discloses armored defenses formed of panels, each of which is formed of a layer of impact-resistant parallel rods, separated among them, made of a ceramic material. The volume which is not occupied by the rods is filled with an elastomer material in which the sound propagation speed is much lower than in the material of the rods.
  • Document 682,810 corresponds to a similar system, which comprises a cover of round caps, mounted and fixed on a reticulate support structure, formed of layers and intercrossing steel cables fixed to an internal structure or armor.
  • the impact of each projectile would determine the oscillation of the affected cap(s) and the unstabilization of the projectile, increased by the vibrating movement caused by the impact and transmitted to the whole system.
  • an antiballistic packet of improved antiballistic capacity which comprises a combination of:
  • Figure 1 is a schematic front view of the anti-ballistic structure of one of the preferred embodiments of the present invention.
  • Figure 2 is a schematic side view of the structure shown in the previous Figure 1.
  • Figure 3 shows different alternatives forms of the energy absorbing element or unit, which perturbs the path of the projectile and shown as an example in Figure 1.
  • FIGS 4 to 8 are illustrations of other preferred forms of the structure of this invention, in which:
  • Figure 4 is a partially cut detailed upper view of said structure
  • FIGS. 1 and 5' are partially cut away views of an antiballistic packet in accordance with the present invention.
  • FIGS 6, 7 and 8 are other partial cross-section views of the packet illustrated in figures 5 and 5'.
  • reference 10 corresponds to a panel or screen which constitutes one of the preferred embodiments of the antiballistic structure of this invention, which includes an elastically deformable matrix 11 and a plurality of rigid elements 12 inserted into said matrix 11.
  • reference 13 corresponds to the panel illustrated in Figure 1, which has been completed with a frame or support of the assembly.
  • the distribution of the rigid elements 12 does not follow a specific plan.
  • the distribution is compatible with the objectives of this invention; as the case might be, it is possible to resort to the orthogonal distribution of elements 12 and even to a distribution having circular symmetry, organizing such elements in concentric arcs or circumferences or in combination with the lineal distributions mentioned above.
  • the rigid elements 12, in combination with the elastic characteristics of the matrix 11, have a fundamental role in the perturbation of the ballistic capacity of the projectiles directed towards targets protected with defenses which include structures as the one illustrated in figures 1 to 3.
  • the perturbing effects of the ballistic capacity correspond mainly to: - the deviation of the path of projectiles which get into contact with elements 12. If the impact is frontal, the elastic deformation of the matrix in the impact zone will occur and same is elastically transmitted to the whole structure. Depending on the elastomeric characteristics of the matrix and the ballistic capacity of the incidental projectile, the breaking and destruction of the matrix in the impact zone may occur.
  • a bounce effect similar to the one observed when a stone is originally thrown in descending direction on a water surface may additionally occur.
  • the stone bounces against the surface of the water surface and is shot in ascending direction, in an angle which varies according to the initial velocity and the angle which forms the entry path of the stone in relation to the water surface.
  • a similar phenomenon occurs when a projectile with an oblique path reaches the surface of an element 12, from where it is shot in this direction, going away from the target.
  • the slantwise strike of the projectile involves a drag which partially consumes the kinetic energy of the projectile and reduces its speed, leading to the obvious reduction of the reach of the projectile and of all the ballistic effects which depend on its kinetic energy (velocity).
  • the energy taken away from the projectile in the impact zone elastically extends to the whole panel structure.
  • Figure 3 shows different possible forms of the energy absorbing elements.
  • the antiballistic effectiveness of the preferred structure according to figures 1 to 3 obviously depends on the mechanic characteristics of units 12 and the elastic characteristics of matrix 11.
  • the optimum number of elements 12 is conditioned by the size of said elements. Said elements shall be distributed leaving a certain margin between each other, sufficient to permit the flexion of the mass of matrix 11 located between one element and its neighbors.
  • elements 12 are units sufficiently rigid and resistant to undergo the slantwise strike and the frontal strike of projectiles.
  • the materials which have proved to be particularly suitable are ceramic, tempered glass or metal materials, particularly ferrous alloys used in the construction of conventional armors and hardened vitrified materials.
  • the systems or structures according to this alternative of the invention have, for example, the form of panels or screens spatially distributed to protect fixed installations or vehicle components when they refer to movable units, including vessels or airplanes.
  • the structure according to this embodiment of the invention may be further used in association with other conventional armored structures, for example, in armored vehicles, security boxes, defense walls, and even in combination with mobile or fixed antiballistic packets.
  • FIG. 4 Another of the preferred embodiments of this invention is partially illustrated in figures 4 to 8, which forms part of an antiballistic packet also schematically and partially illustrated in the above mentioned figures and identified under reference 101.
  • Said packet 101 combines another of the preferred embodiments of the antiballistic structure of this invention with reference 102 associated with a band or block 103 (hereinafter simply called “separator") juxtaposed to an armored structure or armor B schematically shown in Figures 4 to 8 (for example, a conventional shield or armor of ballistic laminated steel, such as laminated Krupp HFX 220 steel and/or aramid laminates reinforced with glass or carbon fibers).
  • a conventional shield or armor of ballistic laminated steel such as laminated Krupp HFX 220 steel and/or aramid laminates reinforced with glass or carbon fibers.
  • This preferred embodiment of the antiballistic packet 101 of the present invention does not essentially depends on the nature and structure of the conventional armor B.
  • any antiballistic packet or armor capable of handling unstabilized and partially stopped projectiles, emerging from the bottom of structure 102 on their way to the target.
  • the novel component of the antiballistic packet illustrated under reference 101 in Figures 4 to 8 is structure 102, which has a fundamental role in the accompaniment and initial unstabilization of the incidental projectiles 15 (Figure 7) in view of the elastic strike or impact of the projectiles with the rigid balls 104.
  • the antiballistic structure 102 comprises a cellular panel 106 formed of a plurality of cells 107 having a regular distribution; for example according to a honeycomb model (quincunxes), as illustrated as an example in figures 4 and 5, or also in an orthogonal distribution or under the form of concentric circles (circumferential symmetry).
  • the cells 107 have a circular section.
  • cells having a polygonal section such as, for example, square, hexagonal and octagonal sections indistinctly, even combining in the same panel cells having a different section.
  • a rigid little ball 104 is housed in each cell 107.
  • An important element for the purposes of this invention is the rigid nature thereof, (i.e. non deformable or elastically deformable as a result of the impact of the projectiles 15).
  • the materials which are suitable for the balls 104 are ceramics, tempered glass, including sintered metals (steel) or polymers, especially aramides reinforced with carbon or glass fibers.
  • each little ball 104 is freely confined in its cell 107.
  • each ball 104 can be loose or compressed within its cell walls so that even if its movements may be severely restricted by the walls, each ball may oscillate or vibrate in its cell and to a certain extent move itself as much as the resiliency of the cellular structure of panel 106 might permit.
  • the balls 104 are very light in relation to the mass of the projectile 15, the extent of the disturbed zone is greater (the lighter balls are shot at a greater speed), the panel 102 is destroyed and the unstabilization of the projectile 15 is lower or does not occur at all.
  • the panel 106 is a polygonal sheet, preferably of square or rectangular section, including the cells 107, as illustrated in the drawings.
  • the panel 106 can be a base sheet acting as a tray, from which tubular projections equivalent to cells 107 project vertically. Said tray is surrounded by a perimetral border.
  • the above mentioned cells 107 are closed by a non-rigid cover 105 working as a lid, extending from one end to another end of the panel 106.
  • This cover 105 and the panel 106 may be of identical or different --obviously non rigid-- materials.
  • this characteristic of non rigidity is important to reduce to the minimum the bouncing of the projectile 15, since according to the principles disclosed herein, this invention refers to the provision of a relatively weak target from the antiballistic point of view to the incidental projectile 15 on the impact point, the projectile having a penetrations which shall affect a reduced area surrounding the impact point and which shall deeply affect a limited number of balls with the breaking of 2 to 4 balls (figures 6 to 8). So starts a chain of elastic strikes from the balls 104 which surround the impact zone and there commences the propagation of the strike wave in the core of panel 106, to an extent proportionate to the energy subtracted from the striking projectile 15 by the balls 104 affected by the direct impact and transmitted by the elastic strike thereof to the immediately neighboring balls 104.
  • each projectile 15 (figure 6), subject to its energy, shall cause the fracture and/or the movement of a certain number of balls, starting the propagation of the energy subtracted from the projectile discounting the energy consumed in practice by the fracture of a certain number of balls in the impact point in response to the elastic strike of each perturbed ball with the balls in the neighboring cells.
  • This proves the importance of the non rigid nature of the material which forms panel 106 and the sheets of the frontal cover 105, to achieve the maximum dispersion and dissipation possible of the energy subtracted from the projectile.
  • Materials appropriate to form panel 106 and the sheet 105 are the polymeric resins which adapt themselves to produce the above mentioned undulating effect, which, added to the elastic strike, are the basis of this invention.
  • Such resins are, for example, polypropylene resins, polyurethane resins, silicone elastomer, synthetic rubber, polysobuthane, estirene butadiene rubber, etc.
  • Cellular structures of this kind which have proved to be useful for the purposes of this invention are obtained by the stamping or inlay of sheet of the materials mentioned above, having a suitable thickness (0.5 - 1.0 mm).
  • the panel can be reinforced included a knitted cloth or felt-like fabric, extending, for example, on the bottom of the panel 106 below the cells (not illustrated).
  • the projectile is unstabilized when it strikes a target, it loses its velocity, changes its orientation and given the case, it deforms itself to a variable extent, depending on whether the strike with the target is elastic or non elastic. If it is a non elastic strike, the energy of the projectile is consumed as a result of the deformation and perforation of the target in the impact area, as it occurs with conventional armors and structures which offer a passive resistance to the impact based on the thickness, the type of material and the resistance to the ballistic penetration (Brinell hardness) of armors.
  • the projectile 15 When the strike is elastic as proposed and disclosed in this invention, the projectile 15 is also unstabilized and loses its orientation when it elastically strikes the ball(s) 104.
  • the strike is elastic because the head of the projectile is rigid and the balls are also rigid and in addition, because the set of balls confined in their cells 107 form a plurality of movable targets: some receive the direct impact of the projectile (figures 6 and 7) and are generally broken.
