尾流自导鱼雷直进射击系统误差的提前角修正方法

针对尾流自导鱼雷直进射击方式下弹道简化产生的命中结果系统误差问题,采用几何分析法,首先,分析了尾流自导鱼雷的直进射击原理;然后,依据尾流自导鱼雷弹道过程,建立了尾流自导鱼雷命中点偏差的解析计算模型,并分析了该偏差对鱼雷命中效果的影响;最后,研究了消除该系统误差的提前角修正方法。通过实例论证了该修正方法的可行性和有效性。

Lead Angle Revise Method for Systematic Error of Straight-forward Shooting by Wake-guided Torpedo

To solve the problem that the trail simplification of wake-guided torpedo shoots straight-forward brings systematic error to hit result. In this paper,the straight-forward shooting mathematical principle of wake-guided torpedo is analyzed,and analytic models of hit result error are established in accordance with the trail of wake-guided torpedo through geometrical analysis. Besides, this paper analysis the influence of hit result error,moreover,the torpedo lead angle revising method to eliminate systematic error is researched. Example result demonstrates the feasibility and validity of the proposed method.
