Definitions

  • the technical sector of the present invention is that of means for protecting various structures using independent shielding modules against ballistic attacks.
  • Adaptive protection of structures involves the production of independent modules containing armor concepts adapted to the threat.
  • these structures can be designed to receive removable protections and therefore adaptable to the mission or the wishes of the user without any other modification.
  • These structures may also receive temporary protections.
  • modules contain materials of all kinds which can be unsealable, or indestructible, and which must be rigidly maintained inside boxes which will be fixed to the structure to be protected.
  • the object of the present invention is to provide a shielding module which meets the requirements set out above, while retaining its initial characteristics throughout its period of use.
  • Another object of the present invention is to provide a shielding module that is simple to manufacture and to arrange to protect the structure in question.
  • Another object of the present invention is to allow the production of shielding modules of various shapes.
  • the subject of the invention is therefore a shielding module of the type comprising a casing surrounding a stack of shielding elements, intended for the protection of a vulnerable structure, characterized in that it comprises a set of shims applied to each face internal envelope to delimit a free space between the stack and the envelope receiving an injectable or pourable cushioning material, polymerizable in situ.
  • the preamble of claim 1 is based on DE-A-3 508 848 or US-A-4 969 386.
  • the cushioning material consists of a polyurethane resin which has a thickness of at least 0.5 mm.
  • the stack of shielding elements is composed of four elements chosen from the group consisting of the following materials: glass, rubber, metal, organic material, ceramic ...
  • a layer of foam is placed between two consecutive plates with a density of 0.20.
  • the envelope of the shielding module is constituted by a box inside which the stack is placed and a cover fixed to the box, for example by welding.
  • this envelope may consist of a set of plates applied to the corresponding faces of the stack, fixed to each other for example by welding.
  • the shielding module can have a rectangular profile, T, Z, trapezoidal or crown portion and, more generally, an envelope whose profile can be adapted to the structure to be protected.
  • An advantage of the present invention lies in the fact that the shielding modules can be produced from any type of shielding element.
  • Another advantage lies in the fact that the shape of the modules can be adapted as a function of the structure to be protected, without any particular arrangement thereof, apart from the means for fixing the modules to said structure.
  • the shielding module illustrated in FIG. 1 comprises an envelope 1 made up of a box 2 and a cover 3 joined by a weld 4.
  • the envelope can be made of steel, aluminum alloy or titanium, and any metallic or non-metallic material adapted to the user's wishes.
  • the envelope can be made of armored steel and thereby participate in the resistance against perforation.
  • the thickness of the envelope depends on the external dimensions adopted, the total mass and possibly the method of attachment to the structure. Concretely, a module of the order of 30 kg and a volume of 13 dm3 has an envelope 1 of thickness between approximately 1 and 5 mm.
  • the box 2 is provided on its bottom 5 with a set of shims 7 regularly spaced in polymerized setting resin maintained with an adhesive compatible with its nature in order to avoid any displacement of these. Shims are also glued to the side walls 6 of the box 2.
  • These shims 7 can be of the cylindrical or parallelepiped type but of equal height so as to delimit an almost constant space between the envelope and all of the shielding elements . They can also be in the form of plates.
  • the free space between the casing 1 and the plates 8-11 is filled by casting, by gravity or by injection using a polymerizable resin, for example a polyurethane resin. After hardening of this resin, one obtains the layer 13 of cushioning material whose physical characteristics of compressive strength and creep are sufficient to hold the plates 8-11 in place.
  • insertion holes 12 and vents 14 are provided to ensure an adequate distribution of the wedging material. It is not essential to provide the holes 12 and the vents 14 on the cover 3. These can be on any wall, their position and their diameter are fixed according to the shape, the dimensions of the envelope. and convenience of filling. After polymerization of the resin, the tap holes 12 and the vents 14 are closed by threaded plugs, or welded or fixed by any process, if the wall of the envelope is thick enough not to bring its internal face to fusion in contact with the packing material 13.
  • the nature of the plates 8-11 is entirely conventional; it can be glass, rubber, metal, an organic material.
  • the plate 8 is made of metal
  • the plate 9 is made of ceramic
  • the plate 10 is made of rubber
  • these plates having a thickness of 10mm.
  • FIG. 2 illustrates an alternative embodiment, however showing the position of the shims 15 bonded to the side walls 6 of the box 2.
  • the stack of plates consists for example of three shielding plates 16, 17 and 18. Between these plates, a layer of foam 19 with a density of between approximately 0.05 and 0.20 is provided. It provides a reserve of expansion. Indeed, if materials constituting the plates 16-18 are used having expansion coefficients greater than that of the envelope 1, it is necessary to provide expansion reserves so as to absorb the increases in volume, without dangerously constraining the box structure.
  • the resin of the wedging material 13 has a certain elasticity but is nonetheless incompressible. Creep therefore takes place at the level of layer 19 of foam.
  • the casing 1 is in the form of a box 2 and a cover 3.
  • a box by assembling walls around the shielding elements 8-11 or 16-19 of the walls, for example by welding, stapling or crimping.
  • the wedging material 13 is of course obtained as above.
  • FIG 3 there is shown rectangular modules 20 with rectangular profile arranged around the structure to be protected 21 on the side of the threat.
  • FIG. 5 shows the same type of improvement where the modules 23 have a Z shape.
  • the modules 24 have a trapezoidal profile, which ensures a decreasing nesting the effects of the impact of a projectile at the joint.
  • the structure 21 to be protected has a cylindrical profile.
  • the modules 25 then have a crown portion shape.
  • the embodiments of the modules can be arbitrary or combined with one another to perfect, if necessary, the protection of the structure 21 to be protected.
