Calculating of Two Wake Homing Torpedoes Salvo

为了提高尾流自导鱼雷的命中目标概率,采用数学分析的方法,对尾流自导鱼雷的接近段弹道进行了研究。解算分析了射击三角形,得到了提前角的唯一解;分析齐射扇面中线转角射击模型,给出了运用模型的方法和修正该模型的计算公式;分析双雷齐射鱼雷各雷的出管顺序,计算各雷展开角及其转角度数,从而计算出各枚鱼雷的射击参数,为导引段提供了更为精确的解算数据。

In order to improve the probability of wake homing torpedoes in hitting the target, using the method of mathematical analysis, we studied the trajectory of wake homing torpedo during the closing stage. By calculating and analyzing the fire triangle, we obtained the unique solution of the advance angle. By analyzing the corner shooting model of volley sector neutral, we gave the method of using the model and the calculation formula of modifying the model. By analyzing the firing order of torpedo salvo, calculating ray flare angle and the rotation degree, we calculated the torpedoes shooting parameters. All the works pro- vides more accurate calculating data for guidance section.
