ABSTRACT:
A self-powered fuze apparatus for a projectile containing an explosive charge which comprises a first housing containing a mechanical safety device for releasably preventing undesired movement of a detonator cup holder containing a detonator from an unarmed to an armed position wherein the detonator cup is shielded from the charge to be exploded in the unarmed position and the detonator cup communicates with the charge only in the armed position and the second housing adjacent the first housing containing an electronic safety means for sensing target impact and projectile launch and selectively passing a piezoelectrically generated firing current to the detonator cup only upon sensing a predetermined magnitude target impact only within a predetermined time after sensing the launch acceleration and only when the electronic means is electrically and mechanically connected to the detonator cup in the armed position.
