DETONATING DEVICE OPERATING ON ACTION OF SHOCK WAVE Russian patent published in 1998 - IPC

FIELD: safe initiating devices used in fast-action equipment to localize emergencies and prevent propagation of harmful substances outside point of emergency. SUBSTANCE: case of detonating device houses charges of high explosive of different density. Charge having least density borders on bottom of case or plate put on bottom. In this case thickness δ is chosen from condition A≤δ≤c/B(1/σ_вр-1/K),, where A is thickness calculated by bearing capability in absence of outside load; B=10^-2e,1/Pa s is sound velocity in material of bottom or plate, m/s; K=1,6 10⁹,Pa; σ_вр - is strength characteristic of material of bottom or plate, Pa. EFFECT: enhanced safety and efficiency in usage of this detonating device, decreased operating time and expanded application field. 3 cl, 4 dwg
