直航雷齐射命中间隔的计算与分析

为了更深入地了解直航鱼雷齐射命中原理,在潜艇鱼雷齐射攻击中鱼雷命中间隔是确保被攻击目标不从齐射鱼雷间＂漏过＂的重要射击参数,该文探讨了对直航雷齐射的鱼雷命中间隔计算所涉及的有关问题,研究了各种情况下鱼雷命中间隔的计算公式,分析了其性质,得出了命中间隔与提前角正切成比例等结论。另外发现了一个有趣的现象：鱼雷按逆序发射时,如果目标长度不大,而目标速度较高,且鱼雷出管时间间隔较长,则有可能变成实质上的一种顺序发射。此外,还通过使用MATLAB 6.5绘制数学工具绘制方程曲线的办法来直观地展示鱼雷命中间隔计算公式的性质。

Calculation and Analysis of Hit Spread for Straight Running Torpedo Salvo

Some issues concerning the calculation of hit spread （HS） for straight running torpedo （SUT） salvo are studied. HS is a very important torpedo fire parameter and guaranteeing that the attacked target does not escape from two salvo torpedoes. Methods for calculating HS of SUT for various cases are given and analyzed, and the proportional relation between HS of SUT and tangent of the Read angle is discovered. An interesting phenomenon is observed that a reverse firing order of torpedoes may actually become a forward firing order if the target with high speed is not long enough and the torpedoes are launched with longer time interval. In addition, the software Matlab 6.5 is adopted to visually reveal the properties of the HS calculation formulas.
