The objectives of this research are 1) designing a 3D prototype model for the fuze part which is 30x165 mm cartridges that work on centrifugal force to unlock the fuze at armed and on spring force for self-destruction this is a principle that applies to general anti-aircraft cartridges 2) using to develop specialized engineering data analysis and, then, use the acquired knowledge for prototyping the fuze for 30x165 mm cartridges in the future. The applied technique could extend the lifetime of the fuze to be longer than the pyrotechnical method could. The proposed fuze design consisted of two parts. The first part was a mechanical system which prevents premature or accidental detonation in order to protect users as well as to ensure safety in shipping and storage. The second part of the design was a detonation system. The fuze was ready when the cartridge is fired. While the projectile rotated at the speed of 14,000 rpm, the centrifugal force caused the spring to move to the tip of the fuze. As a result, mechanical parts inside the fuze are unlocked and put in a ready-to-work position, which was known as the armed position. The self-destruction began when the centrifugal force was less than that of the spring as the projectile rotation slowed down, causing the firing pin to move back and impact the primer to initiate detonation.
