CONTACT SENSOR FOR REGISTRATION OF DAMAGE AGENT APPROACH MOMENT DURING FRAGMENTATION SHELL EXPLOSION Russian patent published in 2012 - IPC F41J5/44 

FIELD: weapons and ammunition.

SUBSTANCE: contact sensor for registration of a moment of damage agent approach during explosion of a fragmentation weapon, comprising a substrate from a non-conducting material, on the surface of which a system is placed from two conductors isolated from each other and connected to output terminals of a DC voltage source and closed on top by a protective layer, in it the system of isolated conductors is arranged in the form of a flat spiral from two metal strips, width of which makes a value of (3…6)·V·10^-6, [m], where V, [m/s] - expected speed of damage agent approach towards a sensor, besides, the width of insulating layer between conductors makes not more than 0.3 from the fragmentation weapon body thickness.

EFFECT: higher security of a contact sensor for definition of initial speed of damage agents throwout.
