Abstract
Apparatus mountable in a projectile for utilization with a rotor-type safing and arming mechanism for post-launch self-neutralization of a spinning projectile having a fused warhead and a stab detonator, including a launch-activated battery, an electric detonator positioned sufficiently close to the stab detonator to initiate the stab detonator upon initiation of the electric detonator, and a spin decay switch circuit operatively interconnecting a charged storage capacitor and the electric detonator upon substantial cessation of projectile spin, for delivering power sufficient to initiate the electric detonator. The apparatus includes a storage capacitor charging circuit activated by launch-induced forces. The apparatus further includes a pre-launch shorting circuit electrically connected in parallel with the electric detonator and deactivated by launch forces, and a 'bleed' circuit connected in parallel with the battery activated by launch-induced forces.
