FIRING MECHANISM FOR SHELLS OF MULTIPLE ARTILLERY ROCKET SYSTEMS Russian patent published in 2012 - IPC F42C9/00 

FIELD: blasting operations.

SUBSTANCE: firing mechanism includes installation device, reaction percussion mechanism, safety and arming unit and ignition train. The latter is branched and made in the form of independent parts - ignition part which contains detonating cartridge with intensifying charge, sleeve-type igniter capsule with striker, bursting charge and electric spark igniter, and detonation part containing detonator, lead charges, ignition cap, and explosive electric igniter. The first lead charge and bursting charge are arranged in turning disc of safety and arming unit. Detonating cartridge with intensifying charge and detonator made in the form of a ring and arranged around detonating cartridge are installed coaxially in firing mechanism sleeve. Installation device includes receiving circuit on the basis of inductive communication line, electronic temporary device the output of which is connected to electric igniter of firing part of ignition train. Turning disc of safety and arming unit of firing mechanism is retained in uncocked position with a clock mechanism and spring-loaded action bar kinematically connected to the disc.

EFFECT: higher safety and reliability and improved control possibilities.
