FIELD: explosives. SUBSTANCE: the method is intended for determining the explosive sensitivity and consists in action of cumulative jet on screened explosive under test, detection of the moment of beginning of cumulative jet interaction with the screen and the moment of beginning of explosion process, and determination of explosive sensitivity according to the time delay of explosion process by the following formula:, where δ - screen thickness; t- moment of beginning of cumulative jet interaction with screen; t- moment of beginning of explosion process; ρ,ρ- densities of material of cumulative jet and screen, respectively; W- cumulative jet speed. EFFECT: enhanced accuracy. 1 dwg |
