Fragmentation warhead

Abstract

A fragmentation warhead has a main explosive charge (1) in a fragmentation casing (2) which is closed at both ends by end plates (8, 9). Deformation charges (5a-e) which extend in the longitudinal direction are arranged around the fragmentation casing (2). The fragmentation casing (2) and the main explosive charge (1) are designed to be deformable, in order to force the fragmentation casing (2) inwards before fragmentation formation when the deformation charge (5a-e) is detonated on the side facing the target (17). In order to achieve a situation in which the fragmentation casing (2) is forced in approximately flat on detonation of the deformation charge (5a-e) which faces the target (17), the fragmentation casing (2) is designed such that it can tear off in the region of the two end plates (8, 9) on detonation of the deformation charge (5a-e). <IMAGE>

The invention relates to a A fragmentation warhead according to the preamble of the Claim 1.

Such a warhead is already proposed been. facing flashover of the target Deformation load (s) is the fragmentation casing before Fragmentation of the target-facing side pressed and thus the target area greater Results density than conventional Splitter warheads with rigid fragmentation casing reached. Ie., The fragments that pressed on the Place of fragmentation casing are formed to be directed goal, so do not fly radially apart, as in conventional Splitter warheads with rigid fragmentation casing of Case.

It has been found, however, that the hit density of a such warhead detonatively deformable is fragmentation casing very difficult to reproduce.

Thus, the fragmentation casing can be pressed, must namely not only themselves, but also the main explosive charge become deformed his bar. The deformability of the main explosive charge has hitherto been realized in that one of the main explosive charge a ZENTRA les, has arranged a cavity enclosing tube. By Reflection of the detonation wave to the tube there is however abrupt changes in the direction of propagation of Detona tion wave in the main explosive charge and thereby unterschiedli chen, irreproducible splinters directions.

From DE-GM 88 12 000 a fragmentation casing is known, both at having end regions of weakened material, namely an annular groove or a thread. In the annular groove of the edge of the hood is crimped and screwed onto the thread, the projectile housing.

The object of the invention is therefore, a fragmentation warhead high performance with reproducible high fragment density ready deliver. This is achieved according to marked with the in claim 1 recorded fragmentation warhead reached. In the subclaims are shown advantageous embodiments of the invention.

The invention is erläu reference to the drawings tert. therein show

Fig. 1 shows a longitudinal section through a fragmentation warhead;

Fig. 2 is a plan view of the warhead according to Fig. 1 with parts broken away;

Fig. 3 and 4 schematically shows the fragmentation casing of a conventional or the deformable detonatively Splitter invention combat-head after the deformation and

Fig. 5, the fragmentation casing in the area of the end plate Fig. 1 in an enlarged view.

According to Fig. 1, the warhead a Main explosive charge 1 in a cylindrical shell 2 on, the outside. with a splinter of occupancy eg cubical chips 3 is provided. To the splitter occupancy 3 extends a damping layer 4, For example of plastic.

On the outer side, the damping layer 4 in Longitudinally extending the warhead Depressions, where deformation charges 5ae in Form of explosives strips are arranged (Fig. 2). Between the wells with explosives strips 5ae, the damping layer 4 longitudinally extending lands 6 on. In the webs6 are located in Longitudinally extending strips 7 of metal or another metal having a different Shock wave impedance than the material of the webs 6 provided. This sandwich is a Damping of the shock waves at a Detonation Deformation load, ie, for example the deformation load 5A relative to the adjacent deformation load 5b achieved.

At its two end faces is the fragmentation casing 2 With endplates 8th. 9 closed. On one plate8th is the firing chain for the detonation of the main explosive charge 1 arranged that an electric detonator 10a transfer charge 11 and a booster charge 12 includes.

To initiate the deformation load 5ae is any deformation load 5ae an electric detonator 13 assigned, via a fuse 14 with the associated deformation charge 5ae is connected. The deformation charges 5ae are thus controlled individually.

The fragmentation casing 2 is connected to the end plates 8th and 9 firmly connected, for example by screws, as in the endplate 9 is represented by the screws 15 in a flange 16 to the sheath 2 are screwed, or for example welded, as with the end plate 8th in Fig. 1 shown.

According to the invention, the fragmentation casing 2 at both endplates 8th and 9 upon detonation of Deformation load (s) 5ae tearable formed.

Ie., While conventional with a Fragmentation warhead with detonatively deformable sleeve 2 the deformation load (s) at the target 17 facing Side sheath 2 correspondingly Fig. 3 by the solid Conjunction with the end plates 8th. 9 to a Push hyperbolic or parabolic surface, that the splitter 3 accordance with the arrows 18 in very depart different directions, in which Warhead invention by the tearing of shell 2 at the two end plates 8th. 9 correspondingly Fig. 4 the sheath 2 on the target 17 side facing substantially flat pressed, so that the splinters 3 accordance with the arrows 19 with reproducible Results density depart towards the goal. Ie., The splitter3 fly in the in Fig. 4 flat shown Training by the deformation load 5ae indented side of the sleeve 2 substantially parallel on the target 17 to. Instead of the flat training can According to the invention, the shell 2 on the target 17 facing side and slightly concave or convex are pressed cylindrical so that the splinters 3 on an axis parallel to the longitudinal axis line warhead be focused or diffused light.

Such parallel or slightly converging or diverging leaving the splitter 3 is on a view the accuracy of today Zündsensoren optimal. Ie., a concentration of the splinters 3, For example, a point is because of the inaccuracy of Zündsensoren not useful.

Compared to the in Fig. 3 shown "Two-dimensional" deformation of the shell 2 give the "One-dimensional" deformation of the shell 2 after Fig. 4 in Elevation direction, like a cylindrical warhead with a rigid shell, at least the same Splitt opening angle and a concentration of splinter 3 in azimuth. Ie., According to the invention varies the angle Epsilon frag sheaf in Longitudinal direction of the warhead in practice by approximately at most +/- 30 °, especially at most +/- 10 °, as in Fig. 4 shown, in contrast to the warhead after Fig. 3, where there is no reproducible angle Epsilon frag Garbe arises.

To a defined tearing of the fragmentation casing 2 at Detonation of deformation charges 5ae reach , the fragmentation casing 2 preferably around her Peripheral line of weakness near the two endplates 8th. 9 on.

As in Fig. 5 shown, this can Lines of weakness by a circumferential groove 20 in the shell 2 be formed of a small distance from a adjacent endplate 8th. 9 is provided. A low Distance a line of weakening or groove 20 of the endplate 8th. 9 has the advantage that no Explosive charge grains of the main explosive charge 1 between the shell 2 and end plates 8th. 9, Ie between Metal parts may be crushed, whereby the Main explosive charge 1 prematurely reacting or Detonation can be brought.

According to Fig. 5 is the case 2 with its outer circumference and its inner circumference with a stop 21 or. 22 at. Of the stop 21 is a ring around the sleeve 2 arranged and the stop 22 formed as a disc. The thickness of around 21 and the disc 22 corresponding to the distance a between the groove 20 and the end plate 8th,

The Ring 21 and the disc 22 the shearing the envelope 2 at the score line or groove 20 by the pressure of the adjacent cube splitter 3 at Detonation of deformation load 5ae supported. The disc 22 and the ring 21 preferably consist of Plastic. Thereby, a clamping of the Explosives grains of the main explosive charge 1 between the torn envelope 2 and end plates 8th. 9, from Metal, or rubbing between metal parts prevented. Instead of the shown in the drawing Cube shape can Splitter 3 in other ways be preformed. Also, the groove20 instead of in Fig. 5 shown round training example its rectangular shape and place on the inside on the outside of the sheath 2 be provided.

According to Fig. 1 is the space between the shell splinters 2 and end plates 8th. 9 entirely through the Main explosive charge 1 filled. While this is the Simplicity of design of the warhead benefit. characterized Similarly occur no inhomogeneities Detonation waves inside the main explosive charge 1 on which the performance of the warhead affect, as in the known Explosive charges with central tube of the case.

On the other hand, the main explosive charge must 1, the after the deformation of the sheath 2 by the deformation charges 5ae by priming 10-12 is ignited in turn be deformed, so that the shell 2 can be pressed. This can The invention also teaches by the weakening lines or groove 20 be achieved. Ie., The groove20 can so be dimensioned such that at least one, for example. The Endplate without priming 10-12, That is, the end plate 9 tears off, so that the main explosive charge 1 when pressed the envelope 2 on the target 17 facing page this end face to the outside of the envelope 2 dodge can.

The strength of the casing 2 at the lines of weakness or the groove 20 is preferably designed so that the tear endplates until a predetermined Internal pressure has been reached. This provides a highly compressed explosive charge 1Which in turn a high Detonation speed and thus a high Splitter speed results. Moreover, by In addition to high density, a homogeneous distribution of the Main explosive charge 1 achieved, so that a smooth Detonation front occurs, the low for a uniform acceleration of Splitter 3 is.

Instead of a line of weakening or groove 20 at the two End faces of the sleeve 2 can at the mounting endplates 8th. 9 by screws, as in Fig. 1 for the with screws 15 fortified endplate 9 shown also by the number and strength of the screws 15 the Strength of the connection of the fragmentation casing 2 to the each end plate 8th. 9 be adjusted.
