Definitions

  • the invention relates to a protective element for protection against ballistic projectiles with several armor plates, which are each formed as a multi-hole perforated plate and a military vehicle with such a protective element.
  • Protective elements are used in military applications on vehicles and other facilities, such. As buildings and weapons used to ward off dangers of various kinds.

  • the invention has the object to increase the protective effect of the protective element against bombardment.
  • the material of the armor plate is removed so that the perforated armor plate has a reduced weight compared to a solid armor plate.
  • the weight of the entire protective element can thus be reduced by the perforated plate.
  • the protective element according to the invention can have a level of protection that is comparable to the level of protection of a protective element with a solid armor plate.
  • a projectile striking the perforated plate can be broken up at the holes and / or divided into several parts, so that its penetrating power can be reduced. Parts of the projectile can pass through the holes of the perforated plate and thereby tear the projectile.
  • impacting projectiles can be deflected at the edges and / or inner walls of the holes.
  • This effect of the holes also has a positive effect on the protective effect, since deflected projectiles can have a reduced kinetic energy and thus can be repelled more easily.
  • the invention can provide a reduced weight protective element whose protective effect against ballistic projectiles through the holes is not adversely affected.
  • the holes of the perforated plate may be formed as the armor plate completely penetrating through holes. But it is also possible to form the holes as blind holes, which penetrate the armor plate only partially.
  • the material of the armor plate may have a thickness which is at most 50% of the thickness of the holes surrounding the holes Material, preferably 10% of the thickness of the material surrounding the holes, more preferably at most 5% corresponds to the thickness of the material surrounding the holes.

  • the breadboard can extend over the entire surface of the armor plate facing the bullet threat, providing full-scale ballistic bullet protection.
  • the size of the holes is chosen to be smaller than the caliber of the impacting projectiles, so that a projectile can not penetrate a hole without being broken up or broken up. Effective protection against bullets of caliber 7.62 mm can be achieved, for example, if the holes have a diameter of 7 mm.
  • the holes of the perforated plate can basically have any cross-sectional area.
  • the holes are formed with a circular cross-sectional area, so that they can be introduced as cylindrical bores by a drilling tool in the armor plate.

  • the protective element has a damping layer for absorbing kinetic energy of impacting projectiles.
  • the damping layer is arranged on a side facing away from the threat of impinging projectiles of the perforated plate. Due to the elastic effect of the damping layer on the surface of the perforated plate, which is hard in comparison to the damping layer, the projectile of the projectile-forming charge can be stopped for a short time. In this case, the tip of the projectile can deform and the material of the projectile laterally along the surface of the perforated plate flow along, so that the projectile is widened.
  • the damping layer is arranged between two perforated plates, so that the projectiles in the layer structure of the protective element can be repeatedly expanded, divided and / or deflected.
