双速制声自导鱼雷射击提前角及变速时机研究

摘要

In this paper ,the antisubmarine characteristic of daul-speed accoustic homing torpedo in target searching section is analysed firstly,a conception of advance angle range is presented according to speed changing in straight-running segment,then the caculation model of speed changing moment is structured based on the course stay the same befor and after the torpedo speed changing, Finally the mathematical model is emulated using the iterative method and the result show that the model is reasonalble and convenient .%双速制声自导鱼雷直航搜索阶段速度的变化给射击提前角的计算带来了新的挑战，通过对双速制鱼雷直航搜索阶段速度配置策略的分析，提出了特定战位条件下双速制鱼雷射击有利提前角范围的概念，建立了在选定射击提前角的前提下鱼雷变速时机的计算模型，仿真结果表明此方法思路清晰、步骤简单，结论合理，为双速制声自导鱼雷有利提前角和变速时机计算作了理论探讨，具有一定的实用价值。
