AXIALLY SYMMETRIC INITIATION ASSEMBLY WITH CUMULATIVE FUNNEL OF WARHEAD Russian patent published in 2016 - IPC F42B1/24 

FIELD: blasting operations.

SUBSTANCE: invention relates to explosives, particularly to axially symmetric assemblies of initiation with a cumulative funnel of the warhead. Axially symmetric assembly of initiation of with a cumulative funnel of the warhead comprises a bottom part of the main explosive charge, a lead charge of cylinder-conic shape, a detonator and a channel located coaxially with the cumulative funnel. Lead charge is installed in the bottom part of the main explosive charge coaxially with the cumulative funnel. Lead charge is made using an explosive material with high detonation capacity on the basis of an explosive substance with low critical diameter of detonation. Lead charge consists of two parts. One part is made in the form of a lens depressed together with the cumulative funnel in the main explosive charge. Second part represents a detonation wave generator coupled with the explosive substance of the main explosive charge. Generator is made of two plates, between which there is an explosive charge.

EFFECT: provided is higher armour-piercing ability of the warhead.
