Projectile or warhead

Abstract

The aim of the invention is to obtain great final ballistic effectiveness of fragmentation bullets and warheads regardless of the impact speed while using as little explosive material as possible. Said aim is achieved by combining explosive shell (3) with a damming inner member (4) in connection with an accelerated outer jacket (2). This arrangement results in the best possible conversion of the explosive energy while offering great creative flexibility regarding the design. A wide range of additional possible effects is created by blast-compacting the inner damming member (4). Furthermore, the shape of the inner damming member allows the fragments to obtain a directionally controlled effect. Depending on the caliber and technical design, the amount of explosive material used can be reduced by 50 to 80 percent compared to conventional explosive bullets at comparable fragment speeds or sub-bullet speeds. The explosive material economized is available as additional effective mass. The accelerated jacket (2) can also be entirely or partly composed of preformed fragments or sub-bullets.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]The present invention concerns a fragments-forming or subprojectiles-forming projectile or warhead.[0003]2. Technical Background[0004]Explosive projectiles are used in order to achieve final-ballistic effects in regard to extensive easy targets independently of the impact velocity of a projectile or warhead, by means of explosive-accelerated fragments, with a great initial velocity. Explosive projectiles of that kind are characterised in that the volume thereof is for the major part occupied by explosive. By virtue of their structure explosive projectiles or explosive-filled warheads contain a comparatively large mass of explosive which is not effective for a considerable part thereof or which cannot have any effect at all in part for physical reasons. Structural design freedom is thus severely limited in the case of the munitions known hitherto and is concentrated on the design configuration of the fragmentation casing...

AI Technical Summary

Benefits of technology

[0012]The aim of the present invention is final-ballistically high effectiveness of fragmentation projectiles and warheads independently of the impact velocity when using a mass of explosive which is as slight as possible. That is achieved by the combination of an explosive casing with a damming or stemming internal body in conjunction with an external jacket which is accelerated to high velocity. That arrangement not only provides the best possible conversion of the explosive energy but it also affords a high degree of structural freedom in terms of the design of such munitions or warheads. The fragment or subprojectile velocities which can be achieved with relatively slight explosive coverings are between a few 100 m / s and close to 2000 m / s and are thus close to those of pure explosive projectiles. Blast compacting of the internal damming body affords a wide range of additional operative options. In particular there is the possibility of using the internal body for increasing the effectiveness of the entire system. Examples in that respect are the use of specific materials, multi-layer arrangements, the incorporation of subprojectiles and the integration of an additional central pyrotechnic component for breaking up and / or accelerating the internal body. Furthermore the design configuration of the internal damming makes it possible to achieve a directionally controlled action on the part of the fragments, which is not possible with conventional explosive projectiles in that form. Particular effects can also be achieved by the integration of reactive damming components in the penetrator or warhead interior. In conjunction with structural advantages and the possibility of using further operative components the overall effectiveness of the fragment-accelerating munition proposed here is far beyond that of known explosive projectiles or special munitions.

Problems solved by technology

Furthermore the design configuration of the internal damming makes it possible to achieve a directionally controlled action on the part of the fragments, which is not possible with conventional explosive projectiles in that form.
