基于单总线的弹载装订系统设计

针对常规弹在制导化改造中导航系统初始参数射前装订难题,提出了一种利用单总线通信存储技术的射前初始参数装订方案。为了实现装订数据目的,首先设计弹载装订总体方案,然后搭建了硬件电路及设计了相应软件,最后通过实验验证了该系统的可靠性和传输速度。实验表明该方案通讯可靠性高,通讯速率高,其写入和读取8个字节只分别需要22ms和10ms。该设计为弹药射前参数装订提供了一种可靠的解决方案,在常规弹药的智能化改造和智能引信中具有较好的工程应用前景。     

High Safety and Reliability Electric Detonator

The entry into force of the REACH regulation implies a modification of the low‐cost detonators manufacturing by finding new substances to replace common primary explosives that contain restricted chemicals. Herein, an alternative solution with a two‐stage electric detonator that contains only secondary high explosive is proposed. It is based on a two steps process, first a combustion, then a shock to detonation transition. This initiator shows high safety level and is compliant with the STANAGs and the REACH regulation. Contrarily to the EBW detonators, it can be initiated using low voltage and low current. Power supply system can be therefore very compact that is of great advantage for designing pyrotechnical train that have to be integrated into small pyrotechnical mechanisms.
