Programmable fuze for projectiles

摘要

A fuze for projectiles having electronic circuitry therein for receiving radiated signals having a fusible link connected to the electronic circuitry for altering the operation of the electronic circuitry and a threshold detector for sensing the rupture of the link to place the fuze in a first mode of operation when the link is ruptured prior to firing of the projectile and in a second mode of operation when the link is ruptured within a predetermined time period subsequent to firing of the projectile.
