PIEZOELECTRIC FUZE SYSTEM

摘要

A self-powered fuze apparatus (10) for a projectile (1) containing an explosive charge (3) which comprises a first housing (12) containing a mechanical safety device (14) for releasably preventing undesired movement of a detonator cup holder (16) containing a detonator (18) from an unarmed to an armed position wherein the detonator cup (18) is shielded from the charge (1) to be exploded in the unarmed position and the detonator cup (18) communicates with the charge (1) only in the armed position and a second housing (20) adjacent the first housing (12) contains an electronic safety means (22) for sensing target impact and projectile (1) launch and selectively passing a piezoelectrically generated firing current to the detonator cup (18) only upon sensing a predetermined magnitude target impact only within a predetermined time after sensing the launch acceleration and only when the electronic safety means (22) is electrically and mechanically connected to the detonator cup (18) in the armed position.
