鱼雷攻击有利扇区和不利扇区探讨

鱼雷攻击有利扇区和不利扇区是潜艇和水面舰艇双方进行水下威胁判断以及防御鱼雷攻击必须解决的问题。通过对鱼雷攻击命中条件的分析认为，在舰艇周围存在一个鱼雷攻击有利扇区或不利扇区，我方舰艇可以使用鱼雷攻击目标而目标无法使用鱼雷攻击我方舰艇的区域就是舰艇鱼雷攻击有利扇区，也即目标鱼雷攻击不利扇区。通过对直航目标鱼雷攻击有利扇区和不利扇区的进一步分析表明，其区域大小与敌我双方的航速和所使用鱼雷的雷速、有效射程直接相关，这为水面舰艇或潜艇寻求消除敌方鱼雷攻击有利扇区带来的不利影响的方法奠定了基础。

Discussion on Torpedo Advantageous and Disadvantageous Attacking Areas

The area where our ship can attack target by torpedo but the target cannot attack our ship by torpedo is named torpedo advantageous attacking area of ship, or the torpedo disadvantageous attacking area of target. The research into the torpedo advantageous and disadvantageous attacking areas is to solve the problems of underwater threat judgment and torpedo defense for submarine and surface ship. Based on the analysis of torpedo hitting factors, it is concluded that there is torpedo advantageous and disadvantageous attacking areas around ship. By the further analysis for the advantageous and disadvantageous attacking areas of a straight running torpedo, it is found that these areas are directly correlated with the mutual speeds, torpedo speed and effective hitting range. The research result is expected to lay the foundation for eliminating the enemy torpedo advantageous attacking area.
