Definitions

  • the invention relates to a protective device for protecting an object against projectile-forming mines and / or ballistic projectiles.
  • DE-PS 1 098 412 Armored vehicles with double armor known, in which a preferably segmented in strips front armor is mounted by means of suspension members on the inner shell of the corresponding vehicle at a distance from this elastically yielding.
  • a protective device designed as a composite armor is known, in particular for protecting armored vehicles against projectile-forming mines.
  • This composite armor consists essentially of two layers of a high-strength material, such as armor steel, and a middle layer of a material that is plastically flowable under dynamic load.
  • the middle layer can be a metal, but also a thermoplastic or an elastomer.
  • Another active armor is the DE 31 39 774 C1 removable. This consists of a sandwiched between two plates intermediate layer, which reduces the shaped charge spike and thus the effect of a shaped charge projectile.
  • the protective arrangement consists of a partially filled with liquid protective structure.
  • the trough region is provided with sloping flanks, which, like the flat bottom region, with corresponding right and left side protection modules have a mine protection adapted to these surfaces.
  • An adjustable protection module comes with the DE 103 10 952 A1 published. This is movable from a rest position to an angled active position.
  • the invention has for its object to provide a protective device, in particular for armored vehicles, which is simple in construction and ensures adequate protection against projectile-forming mines and / or against ballistic projectiles.
  • the invention is essentially based on the idea of constructing the protective device from at least two plates made of a high-strength metal, preferably armored steel, which are positively connected only in the edge region and otherwise rest loosely against each other without any gap, so that both plates arranged parallel to one another are under load from mines or shelling largely independently deformable.
  • the protection device is preferably inclined at an inclination angle between 40 ° and 50 ° relative to the vertical vehicle axis.
  • Projectiles created by blasting of projectile forming mines, which typically impact the guard from below, are destroyed by the outer metal plate (second metal plate) and the resulting splinters of the projectile and the outer metal plate are intercepted by the object to be protected facing inner metal plate (first metal plate) or deflected due to their inclination.
  • the inner plate can buckle independently of the outer plate and thus convert additional energy without being penetrated by the splinters.
  • the protective device according to the invention also has the advantages that it is less expensive to produce and has a smaller wall thickness than known double armor or composite armor.
  • the protective properties of the protective device according to the invention can be varied.
  • the level of protection can be adapted to the threat scenario.
  • the protective structure can be repaired by simply replacing the second metal plate, it being advantageous if the second metal plate, similar to the known double armor, consists of a plurality of adjacent segments, which are fastened to the inner metal plate in each case by marginal screw are.
  • Fig. 1 1 denotes a protective device, which is, for example, the lower wall region of a V-shaped trough of an armored vehicle.
  • the protective device 1 consists essentially of a first steel plate consisting of armored steel 2, in which it is in the illustrated embodiment, the outer wall of the tub of the armored vehicle.
  • a likewise made of armored steel second metal plate 3 is disposed on the side facing away from the object to be protected.
  • the second metal plate 3 is connected only in the edge region with the first metal plate 2 by means of screws and is otherwise without clearance loose on the first metal plate 2.
  • Fig. 1 meets a formed by explosive deformation of a projectile-forming mine projectile 5 on the protective device 1 according to the invention.
  • the second metal plate 3 is destroyed in a partial region 6 and the projectile 5 is fragmented ( Fig. 2 ). Both the fragments of the projectile 7 and the fragments 8 of the metal plate 3 generated when the projectile 5 impinges on the second metal plate 3 are caught by the first metal plate 2 or deflected due to their inclination. In addition, the first metal plate 2 is deformed toward the vehicle interior.
  • the invention is not limited to the embodiment described above.
  • the first metal plate does not necessarily have to be the already existing outer wall of an armored vehicle, but the protective device according to the invention can also be fastened as a separate unit on a corresponding vehicle wall.
  • the wall thickness of the vehicle wall will be taken into account for reasons of weight when dimensioning the plate thickness of the first metal plate of the protective device.
  • the protective device according to the invention does not necessarily consist of only two metal plates, but it can also be more than two, made of armor steel or other metal plates (or sheets) are used, which abut each other without formation of a gap (loose) and connected only at the edges are.
