Abstract
An impact part on a projectile permits the activation of detonation systems within a large angular range of contact with a target. The impact part is provided with annular recesses with embedded circular rings that engage with the target and prevent the projectile from rebounding. A thin-walled, dome-shaped tip prevents relatively large disruptive effects upon the projectile's hollow charge. As a result of dimensioning the impact part in accordance with the rules of fracture mechanics, it is possible to achieve a desired fragmentation on the target.
Claims8
An impact part of a projectile which contains at least one active charge and one detonation device activated upon impact, the impact part being constructed in the form of a bossed cap having a tip and lateral walls with a cavity bounded thereby, characterized in that the tip is thin-walled relative to the lateral walls, at least two annular grooves concentric to a flight direction F extending along a main longitudinal axis of the projectile are let into externally facing sides of the lateral walls, the annular grooves having forwardly-directed sharp edges for target engagement, the annular grooves each having an elastomer embedded therein, the externally facing sides of the lateral walls being free of elastomer in areas separate from the annular grooves.
