HOLLOW CHARGE DEVICE

摘要

A hollow charge device comprising an explosive charge (1) in the form of an elongate bar which defines a groove in which a liner (3) is supported. The explosive charge (1) is curved such that it defines a portion of a volume of revolution about a predetermined axis (2) and the groove opens radially outward away from the axis (2). An initiating means comprising a single detonator (10) is arranged so as to generate a detonation front propagating radially outwards from the axis (2) towards the explosive charge (1). The explosive charge (1) is thereby detonated and the detonation front reaches the liner (3) substantially simultaneously over the whole area of the liner (3). The liner is thus projected radially outwards relative to the axis (2) in the form of a high penetration cutting jet.
