Definitions

  • the invention relates to a warhead, in particular an explosive projectile, in which an explosive charge is received, which is introduced from behind into the warhead.
  • EP 1 338 860 B1 describes a method for producing a large-caliber explosive projectile, in which initially a shell made of an elastic plastic (liner) is introduced through the mouth hole in the interior of the projectile casing and then the explosive charge is poured into the liner.
  • liner an elastic plastic
  • a liner is necessary in explosive projectiles to decouple due to the different volume expansion coefficients of the explosive charge and the projectile casing material, the explosive charge to the inner wall of the projectile casing with temperature fluctuations.
  • the silicone intermediate layer is arranged in the region of the inner surface of the cavity facing the projectile nose of the blasting projectile and / or in the region of the inner surface of the hollow space facing the explosive projectile.
  • the invention addresses the problem of avoiding unwanted implementation of an explosive charge by heated at launch air in particular in the bottom of the projectile to avoid.
  • the invention is based on the idea to introduce an adjustable protective layer in projectiles filled from behind.
  • This idea allows a simple series production while maintaining the required security.
  • the introduced layer which can also be referred to as silvering, is firmly connected to the explosive charge without air layer. This ensures that sufficient thermal insulation is achieved. Furthermore, it is considered that an initiation of the explosive charge is not affected stronger by a Zündver.
  • the layer thickness can be determined for each type of blasting site.
  • the determined layer thickness is ensured by a contouring tool, for example by means of a casting tool.
  • the compatible with the explosive charge elastic layer is applied evenly by means of the casting tool on the explosive surface.
  • the resulting advantages include the fact that a cost-effective and reproducible at any time introducing the heat-insulating layer is shown.
  • the layer serves as a damping element against unwanted implementation of the explosive charge at loading load, but not as a seal of an exposed explosive charge.
  • the spatial order of the damping mass or the layer introduced is in the bottom of the Ge fencing head. Proposed is a projectile or a warhead with a projectile casing, an explosive charge therein and a closure part, which closes the projectile casing from behind ver.
  • a protective layer is applied at least on a rear explosive charge surface of the explosive charge.
  • the layer thickness of the protective layer is variable.
  • the layer thickness must sufficiently reduce the heat input from the compressed air into the explosive, do not interfere with the initiation of the explosive charge by the ignition amplifier of the ignition chain.
  • the layer is independent of geometry, it should as far as possible be contour-matched to the contour of the explosive charge.
  • the present idea serves as protection against friction and excessive heat input into the explosive charge by compression of the residual air after closing the warhead.
  • FIG. 1 It shows the only figure a projectile 1 with a projectile casing 2.
  • An explosive charge 3 can here completely, partially or without wall adhesion with the projectile casing 2 ver prevented.
  • a rear floor opening 4 is closed by a closure part 5.
  • the explosive charge 3 is introduced in this embodiment from behind in the projectile 1 and the Ge shot casing 2.
  • In the projectile 1 is the projectile head of an unspecified tank mortar or artillery ammunition.
  • the projectile head or the projectile 1 is filled from behind with the explosive or explosive charge 3. This is poured into the projectile casing 2. The amount of Sprengla tion 3 is given. The explosive charge 3 assumes its position within the projectile casing 2 a. Thereafter, a protective layer 6 tion against heat in the Sprengla 3 introduced into the projectile casing 2.
  • the protective layer 6 can also be referred to as silvering.
  • the layer thickness 6 is to be dimensioned so that a sufficient heat insulation is achieved, an initiation of the explosive charge 3 by an unspecified Darge presented ignition amplifier of a detonating chain is not affected.
  • the compatible with the explosive charge 3 protective layer 6 is preferably elastic. This is preferably applied uniformly to a rear explosive charge surface 7.
  • the contours of the explosive charge 3 and the protective layer 6 can be inexpensively manufactured or created in a series production by a shaping casting tool.
  • the projectile 1 is closed by means of closure part 5. There remains only a residual trapped thin layer of air. This air layer is significantly lower than an air layer without an introduced protective layer 6.
  • the protective layer 6 prevents the initiation of heat from the compressed residual union air in the explosive charge 3 and thus an unwanted implementation of the projectile.

Abstract

L'invention concerne un projectile (1) ayant une enveloppe de projectile (2), une charge explosive (3) placée à l'intérieur et une pièce de verrouillage (5). Afin d'empêcher une introduction de chaleur dans la charge explosive (3) à partir de la couche d'air comprimé du projectile, une couche de protection (6) est présente sur au moins une surface de charge explosive arrière (7) de la charge explosive (3). L'épaisseur de la couche de protection (6) peut varier. La couche de protection (6) doit être adaptée aussi précisément que possible au contour de la charge explosive (3).
