鱼雷引信全电子安全系统保险与解除保险逻辑设计

基于解除保险环境激励的特性和识别方式,选择鱼雷初始弹道水压信息、安全距离信息和目标信息作为解除保险环境激励,设计了一种能够切合鱼雷弹道特性的保险与解除保险逻辑,既实现了解除保险环境激励同保险与解除保险逻辑之间的良好匹配,又能保证鱼雷全弹道的安全性.运用马尔科夫理论,对所设计的保险和解除保险逻辑进行了分析,计算得到的安全性指标远大于GJB373A对引信安全系统的要求,能够满足鱼雷引信高安全性的设计要求.

Design for Safety and Arming Logic in Torpedo Fuze of Electronic Security System

Based on the characteristic and identification mode of arming environment excitation, water pressure data of initial trajectory, safe distance data and target information are selected as arming environment excitation, and a safety and arming logic according with the trajectory characteristic of a torpedo is designed to realize good matching of arming environment excitation and safety as well as arming logic, and to ensure the safety of torpedo overall trajectory. The safety and arming logic is analyzed by using the Markov theory, and the calculated safety value is much larger than the criterion in the standard GJB373A for fuze security system, which can satisfy high safety design need for torpedo fuze.
