Abstract:
A fuze device for use with a detonator, comprising:a cup and ogive assembly having an axis with the ogive including an ogive post for rearward axial movement upon impact of said device in the forward direction of travel, said assembly forming an enclosure for axial attachment to a spitback lead on said cup;a centerplate assembly operable as a mechanical firing sensor with a first firing pin and positioned within said ogive;a first safe and arm device axially aligned below said centerplate assembly, said first safe and arm device including a first detonator and a first rotor having a first safety lock setback pin allowing said first rotor to rotate to an armed position by exposing said first detonator to said first firing pin;a second firing pin containing an anti-creep spring positioned below said first safe and arm device, said second pin having a blowthrough hole for alignment of said first detonator with said spitback lead;a second safe and arm device axially aligned below said first safe and arm device, said second safe and arm device including a second detonator and a second rotor having a second safety lock setback pin removable by acceleration upon launch allowing said second rotor to rotate to an armed position by exposing said second detonator to said second firing pin, said second rotor containing a kidney shaped slot thereby to always permit alignment of said first detonator with said spitback lead;whereby impact on said ogive after launch causes said ogive post to initiate said first firing pin to detonate said first detonator and said second rotor in said second safe and arm device impacts on said second firing pin to detonate said second detonator, such that detonation of either the first fuze detonator or the second fuze detonator causes said spitback lead to initiate.
