Abstract:
1. A projectile comprising: (a) a projectile casing in which an explosive charge is arranged, wherein the explosive charge is enclosed by a fragmentation casing; (b) an ejection charge disposed to displace the explosive charge axially with respect to a fragmentation casing when the ejection charge is ignited, wherein the explosive charge is arranged in a jacket, wherein the jacket is a molded part made of plastic or made of a light alloy, wherein the jacket develops no fragmentation action or only a slight fragmentation action during an ignition of the explosive charge, and wherein the molded part is connected to the ignition device via an annular flange part on a side of the molded part facing an ignition device; and (c) the ignition device operably connected to ignite the ejection charge and the explosive charge, wherein the ignition device operates in a first mode and in a second mode, wherein in the first mode of operation, the ignition device ignites only the explosive charge so that the explosive charge explodes in the fragmentation casing thereby ripping apart the fragmentation casing and hurling fragments of the fragmentation casing at high speeds, and in the second mode of operation, the ignition device first ignites the ejection charge, and subsequently the ignition device ignites the explosive charge so that explosion of the ejection charge causes the explosive charge enclosed by the jacket to be pushed out of the projectile casing and the fragmentation casing at least so far that, during explosion of the explosive charge, the explosive charge does not substantially act on the fragmentation casing so that high speed fragments of the fragmentation casing are not hurled by the explosion of the explosive charge.
