INITIATING DEVICE Russian patent published in 1998 - IPC

FIELD: pyrotechnics, igniter structures. SUBSTANCE: initiating device has a metal body with two coaxial ducts separated by an indestructible obstacle. Both ducts have a charge of pyrotechnical composition each: one duct accommodates warming-up composition, the other - igniter composition. The bottom of the duct with igniter composition is made as a hemisphere, and the bottom of the duct with warming-up composition is flat. The ducts are arranged on both sides of the section plane laid through the indestructible obstacle; time of transmission of initiating impulse, 0.1 s. EFFECT: simplified design due to elimination of the requirement of ducts coaxially, which simplifies the production process; reliable sealing after device actuation, reduced overall dimensions; safety in manufacture and use. 1 dwg
