ABSTRACT:
An artillery projectile carrying a multiplicity of explosive mines adapted o be deployed from the projectile during flight thereof is provided with self-destruct fuze means for destroying each mine at a predetermined time, e.g., two days, after deployment. This means comprises a battery carried by the projectile connected prior to deployment to a fuze circuit in each mine. Each fuze circuit comprises a first capacitor and parallel resistor forming an RC delay circuit and a second capacitor connected in series with the RC circuit, an electric detonator and a normally-open spin-closed voltage-responsive circuit. The RC circuit is connected to the battery through a normally-open spin-closed switch and a current-limiting resistor. An electrostatic switch is disclosed as an example of the voltage-responsive switch.
