摘　　要：双雷平行航向齐射,是直航鱼雷提高命中概率的有效手段之一。文中建立了超空泡鱼雷双雷齐射模型,并根据命中方程将齐射两雷一次转角射击等效为直进射击,明确了鱼雷命中目标的实质,即鱼雷末弹道相对速度方向与等效初始目标方位角方向重合,使得齐射问题得以简化。根据鱼雷直进射击规律,以脱靶量作为命中指标、以目标水线面形状作为命中范围建立双雷齐射命中概率解析模型,并考虑诸如平台探测误差、鱼雷航行误差和目标航行误差影响,利用统计方法作为对比试验,试验结果表明解析计算模型与统计计算模型结果相吻合,验证了解析模型的正确性。最后分析了各误差源灵敏度,明确了提高鱼雷航向控制精度和方位探测精度是提升命中概率的有效途径。Parallel salvo method is effective in increasing the hitting probability of straight running torpedoes.This studyestablishes a salvo model of supercavitating torpedoes wherein the shoot with a one-time turning angle is transferred into thatwith a straight-forward shooting.This clarifies the fact that the torpedo hits the target whenever the direction of relativevelocity with respect to the target in the terminal trajectory coincides with the equivalent initial azimuth of the target.Theproposed method simplifies the salvo problem.Herein,an analytical model of the salvo is established according to the law ofshoot with straight trajectory.The miss distance is used as the hit index,and the shape of the target’s water plane is used as thehit range.Moreover,the analytical model considers the effects of platform detection error,torpedo navigation error,and targetnavigation error.Using statistical methods for comparison,simulations show that the results of the analytical model areconsistent with those of the statistical model;this verifies the accuracy of the analytical model.The study also analyzes thesensitivity of each error source and clarifies that improving the torpedo heading control accuracy and azimuth detectionaccuracy is effective in increasing the hitting probability.
