摘要: 为了解决预定相遇态势二次转角射击参数的计算问题, 考虑鱼雷可能的变速及特殊弹道过程, 建立了可满足不同射击方式需求的通用数学模型, 给出了牛顿迭代算法的相关公式。用数值实验的方法对模型及算法的正确性进行了验证, 结论表明模型及算法可满足直航、声自导、尾流自导、齐射、目标选择等射击参数计算的需求。Abstract: To compute the parameters of two-time turn angle shooting of a torpedo for predetermined encountering situation, a general model satisfying the requirements of different shooting modes is constructed by considering possible special trajectory and torpedo velocity change. The formulas for Newton iteration algorithm are given. The correctness of the proposed model and algorithm is validated by numerical experiment, and the results indicate that the model and algorithm can satisfy the computation requirements of the shooting parameters for straight running, acoustic homing, wake homing, salvo, target selection, etc.
