Abstract

Wall armor, comprising inner armor and outer armor disposed at a distance in front of the first, intended to produce the deflection or destruction of a projectile, as soon as its tip has passed through the outer armor, while destroying the armor relatively little exterior in the impact zone, so that the zones adjacent to the impact largely retain their protective power. The gap between the two shields, closed on all sides, is filled with an internal charge exploding or fragmenting when the pressure increases under the effect of the penetration of the projectile, constituted, for example, by an explosive material, glass or ceramic material. The outer armor is made up of contiguous or superimposed plates (B), which can unilaterally pivot outwards.

Description

-16 Shielding wall, for example of shelter or armored vehicle

  The present invention relates to the shielding of a wall, for example a shelter or the body of a shielded vehicle, comprising an inner shield and an outer shield placed at a distance in front of it. So-called double shielding of this type are known,

  for example in the form of plates that can pivot slightly

  German Patent 1 098 412, or in the form of plates resiliently suspended in their plane by US Pat. No. 2,380,393. These arrangements must be

  to obtain an effect of diversion of the projectile.

  this goal has not been achieved so far with

  arrangements, because the intended effect does not occur

  knows that too late, if however it occurred in

  other known structures with double plates between

  which is a medium that projects forward the outer plates at the entrance of the projectile, it occurs,

  which is a disadvantage, in other impacts, a des-

  complete truction of the armor, the direction of movement of the plate or plates, which is to a large extent the direction of movement of the projectile,

  not, moreover, of maximum protection effect.

  Accordingly, the object of the invention is to

  expensive and effectively implement hijacking and even destruction of a projectile, particularly in

  the case of long projectiles, after the point of projection

  tile has passed through the outer armor.

  a relatively small destruction of the

  outside the area of impact, so that repairs

  rations can be easily performed and that areas close to the point of impact largely retain their protective effect. To achieve this objective, according to the invention, the gap between the two shields, closed on all sides, possibly divided into compartments by transverse walls or the like, is filled with a charge of exploding or fragmenting internal material when the pressure increases due to the penetration of the projectile, constituted, for example, by a material

  explosive, glass or ceramic material, and

  outer layer consists of contiguous

  superimposed arranged so that they can be rotated unilaterally

  Some other variants of reali-

  will emerge from the description which follows.

  We thus obtain, thanks to the invention, a bearing

  by definite pivoting of the plate which is precisely

  paid by the projectile Long projectiles in particular

  such as KE ammunition, are thus destroyed and

  turned with the pivoting motion of the plate even before they crossed the plate, which

  greatly reduces their punching power.

  The position of the pivot axis of the plates depends to a large extent on the structure of the wall of the shield to be protected considered in each case, for example the wall of a tower It is not essential that the pivot axis horizontal or vertical, it can also be oblique The pivot axis must be arranged so that the projectile is diverted from the combat compartment which is possibly protected by another shield placed behind this new protection arrangement In the case where the this new protection principle is used as a geometrically separate preliminary module, preceding

  another shielded wall, one can also install effectively

  plates on the back of the module to destroy or

  divert the residual projectile that comes out.

  The appended drawing shows schematically examples of non-limiting arrangements of the plates in the shield according to the invention. In the accompanying drawing: FIG. 1 represents in top view, on a door B, at the top the hinges A and the locks C, in

  the case of a double door with hinges

  res A and locks C; Fig 2 is a top view of the hinges A of opposite sides of two plates and the lock C, as well as a cover D on neighboring sides;

  Fig 3 shows in perspective, in a real-

  modular system, the hinges of two plates on a

  central E, the lock C on the outer sides and a fragmentable garnish G, for example of explosive material, glass or ceramic material, inside the box-shaped module;

  Fig 4 shows, also according to a view in

  for a module, the suspension means A on the face

  top of the plates, a cover D on the sides

  and a weakened weld F on the side edges and bottom edges of the plates.

  Instead of the suspension means indicated in the figures, it is also possible to cut the shielding

  made in the form of a plate, according to the shape of the pivot plates

  only on three sides, so that this plate pivots, during an impact, around the part of material which

  On the fourth side there may also be provision on the remaining side for a weakening of material in order to facilitate pivoting. In each case, however, the fixing of the other three sides, for example by means of bolts or a light weld, must be more flexible than fixing

  The internal charge of material must fill the entire gap between the internal shielding and the outer shielding. To the extent that it is of explosive material, only a small quantity of material, for example in the form of a plate

  narrow, which is then held externally on the inner shield or internally on the outer shield.
