Abstract
A cylindrical shaped charge is a hollow cylindrical liner surrounded by explosive material. Jet formation in cylindrical cumulation is difficult to achieve, but is of interest to researchers due to its features: the high speed of the cumulative jet and the low gradient of jet speeds along the length relative to classical cumulation. To achieve stable jet formation, a two-stage cylindrical charge device has been proposed. The principle of its operation is based on the creation of an overcompressed detonation regime in the internal charge of the explosive. Thus, the speed of throwing the inner shell towards the axis will increase, which will lead to an increase in the angle of collapse of the shell and improved jet formation. A mathematical model of the functioning of such a device is presented, and several options for such shaped charges are considered. From a mathematical point of view, the possibility of functioning of such a device in the overcompressed detonation regime has been proven.
期刊介绍：
Technical Physics is a journal that contains practical information on all aspects of applied physics, especially instrumentation and measurement techniques. Particular emphasis is put on plasma physics and related fields such as studies of charged particles in electromagnetic fields, synchrotron radiation, electron and ion beams, gas lasers and discharges. Other journal topics are the properties of condensed matter, including semiconductors, superconductors, gases, liquids, and different materials.
