ARMY ARMAMENT RESEARCH AND DEVELOPMENT CENTER DOVER NJ LARGE CALIBER WEAPONSYSTEMS LAB
A computer-aided design and engineering approach was developed to study ball rotor safe and arming devices. This approach used mathematical modeling procedures to design inert and loaded prototypes. Ballistic tests guided by a statistical plan were conducted to verify the mathematical models. The inert fuzes were monitored by a flash x-ray system to determine arming distances. A small quantity of 20, 40 and 57 mm projectiles was used. A comparison of the 57 mm results with those of an extensively analyzed and standard 57 mm fuze substantiated the viability of this approach.
