EXPLOSIVE SAFE AND ARMING SYSTEM Russian patent published in 2010 - IPC F42C15/40 

FIELD: explosives.

SUBSTANCE: mechanism comprises vessel, holding firing circuit that includes electric detonator and transmission charge, firing circuit gate, installed with the possibility of displacement under action of compression spring, pyrotechnical stop to hold gate in initial condition, fixator of gate in actuated condition and electric connector for connection with detonating fuse control instrument. At the same time the mechanism additionally comprises electromechanical stop, including step motor, on shaft of which there is a device for conversion of shaft rotary motion into reciprocal displacement of engagement element with gate, and also thermal safety stop for blocking of firing circuit gate in initial condition as safe operation temperature is exceeded. The gate contains two slots to hold it in initial condition by electromechanical and pyrotechnical stops with the possibility of disengagement as per specified sequence of their actuation, and the third slot - for blocking with thermal safety stop.

EFFECT: increased safety of detonating fuse and ammunition at all stages of operation and armed application.
