Abstract
The dud de-arming device serves to de-arm a fuze of a projectile which has remained lying on the ground or the place where it landed as a dud in order to prevent the discovered dud from still exploding when touched or moved. As to spinning projectiles the dud de-arming device should de-arm the fuze after disappearance of the projectile spin and for spinless projectiles the dud de-arming device should de-arm the fuze after a certain time following the impact deceleration of the spinless projectile. The dud de-arming device comprises a rotor which can be rotated by spring force. This rotor can assume an armed or live position due to the projectile spin or by virtue of the firing acceleration. Upon disappearance of the projectile spin or by virtue of the impact deceleration the rotor should assume a de-armed or safety position.
