ABSTRACT:
A projectile casing is designed to insure proper operation of the charges located therein. The charges are spaced by spacer tubes constructed such that the tubes are dispersed radially after the detonation of the preliminary charge without adversely affecting the effect of the following main charge by shock waves and/or vibrations. Solid shock barriers and damping members are provided in addition to a thin-walled projectile casing. Such a construction has proved successful, in particular, for tandem hollow charges, and also for use against active armour plating.
