Regular and centric initiation and further axis-symmetric propagation of the detonation wave have a significant role in shaped charge functioning. The generated form of the detonation wave also represents a very important parameter of metallic liner collapsing and the whole shaped charge effect. The choice of a more acceptable profile of the detonation wave enables the increase of this charge penetrability. From this point of view, some aspects of explosive charge initiation and the possibilities to shape the detonation wave in the shaped charge were considered. In an attempt to generate a detonation wave of a required form in the peripheral zone of the charge, a two-part explosive charge made of explosives with different detonation velocities was analyzed. Some results related to the numerical simulation and experimental testing of the detonation wave in 60 mm caliber shaped charge models are given.

Key words: physics of explosion, shaped charge, initiation, detonation wave, numerical simulation, 60mm caliber.
