Abstract

The invention relates to an explosive projectile (1) with a projectile casing (2) which encloses an interior (4) filled with an explosive (3).
To ensure a defined decomposition of the projectile casing (2) by simple measures, the invention proposes, in the region of the inner surface (5) of the projectile casing (2) an insert (6) of a metal fabric, for example by gluing or pouring to arrange. This metal mesh (6) interferes after ignition of the explosive (3), the further propagation of the explosive wave and leads to a defined diverse decomposition of the projectile casing (2). In addition, the individual members of the metal fabric (6) form additional construction splitter.

Description

The The invention relates to an explosive projectile with a projectile casing, which encloses an interior filled with an explosive.

Such explosive projectiles are for example from the DE 21 26 351 as well as from the DE-OS 28 37 638 known. In these known explosive projectiles predetermined breaking points are introduced directly into the projectile casing to improve the splintering performance. For this purpose, narrow areas of the projectile casing, for example, are melted with laser or electron beams and then cooled in such a way that metallurgical structural changes occur along which the projectile later breaks.

adversely is at these known explosive projectiles that their production is relatively expensive and that due to the strong warming and cooling the near - surface areas of the Projectile shell also underlying areas of the projectile shell be thermally influenced, so that sufficient impact resistance such projectiles and thus the explosive projectiles often can not be guaranteed.

From the DE 199 60 180 B4 Furthermore, an explosive projectile is known in which, in order to improve splintering, predetermined breaking points are not introduced directly into the projectile casing, but rather into separate cupped steel sheet metal parts which are located in recesses of the projectile casing provided for this purpose.

adversely in this explosive projectile is mainly that in the projectile shell corresponding recesses for the steel sheet metal parts are introduced have to. In addition, the predetermined breaking points also in this case by a relatively expensive thermal treatment the steel sheet parts generated.

The DE 198 09 181 C1 discloses a fragmentation warhead, which has a structured deposit to form definier ter splitter from the sleeve between the sleeve and the explosive charge. Inserted in these are plate-shaped insert elements, for example of silicone or plastic.

From the DE 35 10 431 A1 , referring to the aforementioned DE 198 08 101 C1 a warhead for the production of slivers of uniform size can be removed, wherein the embedded here between the warhead casing and the explosive shell liner has longitudinal holes, which together form a lattice-shaped pattern. The insert material proposed is unalloyed steel or reactive alloys. This measure ensures that the shock waves act unimpeded on all four cutting edges of the fragments to be formed and ensure reliable separation at these edges. Between the insert and the explosive a film is also provided here, which prevents penetration of the explosive into the longitudinal holes.

Of the Invention has for its object to provide an explosive projectile which by simple measures a defined decomposition ensures the projectile shell.

These The object is achieved by the features of claim 1. Further, particularly advantageous Embodiments of the invention disclose the subclaims.

The The invention is based essentially on the idea in the field of inner surface of the projectile shell an insert from a metal mesh, for example by gluing or pouring, to arrange. This metal mesh interferes with ignition of explosives further propagation of explosive wave and leads to a defined manifold decomposition the projectile shell. In addition, the individual members form of metal fabric additional construction splitter.

When The use of a wire mesh fabric has proven particularly advantageous proved as deposit for such explosive projectiles, because Such tissues have a relatively pronounced spatial Have shape, which in bending the tissue into a cylindrical shape (ie when the tissue is attached to the inner surface the projectile shell) is reinforced.

It But it can also be provided that it is the metal fabric is a wire mesh or a metal mesh (for example, an expanded metal mesh).

Further Details and advantages of the invention will become apparent from the following Based on figures explained embodiments. Show it:

1 the partially sectioned side view of an explosive projectile according to the invention with a arranged on the inner wall of the projectile casing wire mesh fabric, the explosive has been omitted for clarity, and

2 an enlarged cross section through the in 1 illustrated explosive projectile along the there designated II-II cutting line.

In 1 is with 1 a large-caliber blast projectile referred to, which is a projectile shell 2 which has one with explosives 3 ( 2 ) filled interior 4 encloses.

According to the invention is in the region of the inner surface 5 the projectile shell 2 an insert consisting of a wire mesh fabric 6 arranged, wherein the individual welded together rings, for example, made of stainless steel.

In particular 2 is removable, forms the bent from an approximately flat mat insert 6 in relation to the projectile shell 2 wedge-shaped elevations 7 and depressions 8th , which after the ignition of the explosive 3 a defined decomposition of the projectile shell 2 support, with the rings of wire mesh fabric 6 how light construction splinters work.

The Of course, the invention is not the above described embodiment limited. So can be used as an insert to create a defined disassembly of the projectile shell For example, a wire mesh with appropriately selected (i.e., the splitter size determining) mesh size be used.
