EXPLOSIVE DEVICE Russian patent published in 2023 - IPC F42B3/10 

FIELD: explosives.

SUBSTANCE: explosive device includes a main explosive charge, an additional explosive charge in contact with it along the end surface, an additional explosive charge actuation unit located coaxially with the additional explosive charge. The explosive device is equipped with a detonation delay located between the main explosive charge and the additional explosive charge activation unit. An additional explosive charge is made of at least two n-layers located coaxially, with different densities, the value of which is selected from the condition: a layer with a smaller (ρ_min) density determined from the expression ρ_max =(0.80…0.88)⋅ρ_t, where ρ_t is the calculated theoretical density of the explosive, contacts with a detonation delay, a layer made with a greater (ρ_max) density close to the density of the main explosive charge, determined from the expression ρ_max =(0.92…0.98)⋅ρ_t, where ρ_t is the calculated theoretical density of the explosive; it contacts with the main explosive charge along the end surface. The density of the explosive layer (ρ_medium) located between the layer with a smaller (ρ_min) density and a layer with a higher (ρ_max) density of explosives, is determined from the expression ρ_medium =ρ_min +Δρ, where Δ =(ρ_max-ρ_min)/(n-1), n is the number of layers.

EFFECT: increasing the reliability of the operation of an explosive device when it is initiated.
