EXPLOSIVE DEVICE Russian patent published in 2011 - IPC F42B3/10 

FIELD: explosives.

SUBSTANCE: explosive device can be used during development of explosive devices initiating the detonation in explosive agents of low detonation capacity. Device includes primary charge from explosive agent which is low-sensitive to detonation pulse and additional charge from more sensitive explosive agent with its actuation assembly. Insert from explosive agent which is more high-caloric than the agent of additional charge is installed coaxially to additional charge. Insert is arranged either in the additional charge body, or separates primary and additional charges and contacts along the edge with primary charge. Diametre d_i and thickness h_i of insert is chosen from the following ratios: d_i=(0.8÷1) d_cr; h_i=(0.2÷0.3) d_cr when the insert is made in additional charge body, d_i=(1÷1.2) d_cr; h_i=(0.2÷0.3) d_cr when the insert separates primary and additional charges.

EFFECT: simplifying the device design.
