鱼雷主动电磁引信防误动技术

Anti-false Action Technology for Active Electromagnetic Fuze in Torpedo

针对鱼雷主动电磁引信容易产生误动的突出问题,对引起误动的干扰场进行理论分析,总结出雷内电磁不兼容和鱼雷航行振动是造成引信误动的两类主要原因,从抗干扰设计和保险设计两方面提出了完善防误动设计的具体要求。试验表明,改进设计措施实施后可有效降低误动概率,并可提高鱼雷引信工作的可靠度。同时文中还提出了引信误动概率的计算方法,可用于检验引信抗干扰设计是否符合要求。

This paper analyzes the interference field which causes the false action of active electromagnetic fuze in torpedo, and identifies electromagnetic incompatibility inside torpedo and sailing vibration of torpedo as the key sources. Therefore, the requirements of counter-countermeasure design and safety design are put forward to optimize the anti-false action design. Test results show that the improved designs can effectively reduce the probability of false action and enhance the reliability of torpedo fuze action. Moreover, a method for calculating probability of false action is presented to examine anti-interference design of fuze.
