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.
Claims9
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 are let into the lateral walls, the annular grooves having have sharp edges, the annular grooves each having an elastomer embedded therein to fill and/or project beyond the annular grooves.
An impact part according to claim 8 or 9, characterized in that it comprises an untempered heat-treatable steel.
