The possibility of creating fuzes based on detonation logic, their manufacture with minimal overall dimensions leads to the increase of explosive shell mass, increasing power of the munition. In fuzes with detonation logic missed such critical items as pyrotechnics with small period of storage, impact and prick mechanisms actuating prick percussion caps and blasting caps. Also a lot of mechanical moving parts are absent: detents, sliders, clockworks, clamps, etc. which increases the fuze operation time and reduces its reliability. The possibility of using HE, containing polymers, in fuzes with detonation logic also increases their safety, as these substances are the least sensitive to external influence unlike pure blasting and initiating HE. No mechanical moving parts leads to the possibility of using such explosive devices in designs exposed to high overloads.
In the process, an analysis of the miniature explosive logic devices’ construction fundamentals has been performed, the calculations of the selection of explosive material based on the estimates and weight and size characteristics, worked through the design of miniature safe and arming mechanism, selected material and shape of the detonation logic element as well as a possible variant of its coupling with electronics part of the fuze.
Conclusions
1. This work demonstrates the possibility of the development and usage of safe and arming mechanism with detonation logic device.
2. The calculations confirm the availability of the selected design.
3. Selected HE material provides a safe and arming mechanism detonation logic.
4. Suggested a variant of the design of miniature safe and arming mechanism.References
