Developing a prototype 3D model of fuze parts for the centrifugal force type to unlock the fuze at armed for the 30x165 mm cartridges

Abstract
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 prevented 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 was 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 were 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.
