Research on firing advance angle and start-up opportunity of homing equipment of dual-speed torpedo

双速制鱼雷发射提前角和声自导装置的开机时机是鱼雷发射重要参数,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,建立在选定射击提前角的前提下鱼雷变速时机和声自导装置开机时机的计算模型。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声自导装置开机时机计算作了理论探讨,具有一定的实用价值。

The firing advance angle and start-up opportunity of the initiative acoustic homing equipment are important launch parameters of acoustic homing torpedo. In this paper,the anti-submarine characteristic of dual-speed acoustic homing torpedo in target searching section is analyzed firstly, a conception of advance angle range and the start-up condition of initiative acoustic homing equipment are presented according to speed changing in straight-running segment,then the calculation model of speed changing moment is structured based on the course stay the same before and after the torpedo speed changing,Finally the mathematical model is emulated using the iterative method and the result show that the model is reasonable and convenient.
