一种计算尾流自导鱼雷极限射距的方法

A Calculation Method of the Largest Launch Range for Wake Homing Torpedo

对尾流自导鱼雷极限射距计算涉及的有关问题进行了探讨。尾流自导鱼雷的极限射距与直航雷的极限射距相比,有其独特之处,情况也要复杂许多。尾流自导鱼雷极限射距的精确计算取决于其末端自导追踪弹道的精确描述,而这种描述参数是不可能获得的。为此提出一种近似计算方法,并对该方法进行了深入分析。分析结果表明,这种方法十分简单有效,能够满足潜艇攻击决策的使用需要。此外,尾流自导鱼雷的极限射距不能唯一表达,它随瞄点修正距离而变化。这给该参数在攻击中的使用带来了新的课题,文中对尾流自导鱼雷射击相关参数的选择提出了建议。

Some issues concerning the calculation of the largest launch range （LLR） for wake homing torpedo （WHT） are discussed. The LLR for WHT torpedo shows its uniqueness and complexity over straight running torpedo. The precise calculation of the LLR for WHT depends on the accurate description of the final homing pursuing trajectory of the torpedo, which is virtually impossible. An approximate calculation method is therefore presented and analyzed. The results show that the method is simple and very effective for attack decision making （ADM） of the launcher, typically the submarine. The LLR for WHT is also found not unique but changing with the anticipated impact point, which poses problems in its application to submarine ADM, therefore some solutions are proposed.
