集束子弹药引信自失效、自失能技术路线及典型设计可靠度分析

分析了集束子弹药引信自失效、自失能可采取的技术路线;重点介绍了2 种典型的集束子弹药引信自失效路线;建立了一类集束子弹药引信可靠度模型;应用实验结果求解了引信各模块的可靠度,并应用Monte Carlo 法进行了综合发火率和自失效率仿真。实验和仿真结果说明:引信自毁/ 自失效模块的可靠度指标应高于发火装置的可靠度指标;多管火箭炮系统(MLRS)发射子弹药引信综合发火率较难达到99%;自失效率应单独考核。

Technical Route and Typical Design Reliability Analysis of Fuze Self-neutralisation and Self-deactivating of Cluster Sub-munitions

The technical route of fuze self-neutralisation and self-deactivating of cluster submunitions is analyzed,and the self-neutralisation routes of two kinds of cluster submunition fuze are introduced. A reliability model of cluster submunition fuze is established,and the reliability of all the modules in the fuze is figured out using the experiment results, and the comprehensive firing rate and self-neutralisation rate are simulated using Monte Carlo method. The experiment and simulation results indicate that the reliability of fuze self-damage/ self-neutralisation module is higher than that of firing device. Also, the fuze comprehensive firing rate of sub-munitions launched by multiple launch rocket system(MLRS) is difficult to achieve 99%. Besides, self-neutralisation device is auto-checked.
