Optimal Attack Speed and Leading Angle of Torpedo under Energy Constraint
-
摘要: 鱼雷攻击过程中航速并非越高越好, 因为能量有限, 速度越快, 航程越短。文中研究了在给定雷目攻击态势下, 通过理论分析和数学推导求解最优攻击速度和提前角, 以使鱼雷能量消耗最小, 并在此基础上通过计算和绘图对最优攻击速度、最优提前角、能量与目标舷角的关系进行分析。研究结果有助于延长鱼雷航程, 可为鱼雷的使用和弹道设计及其全航程能量规划提供参考。Abstract: Higher speed is not always appropriate in a torpedo attack because the torpedo energy is limited. The faster of the torpedo runs, the shorter its range becomes. This paper presents a method for solving the optimal attack speed and the leading angle under the constraint of minimum energy through theoretical analysis and formula derivation. Based on the solution the relations among the optimal attack speed, the optimal leading angle, the energy and the target board angle are analyzed. The results may facilitate torpedo application and trajectory design as well as energy planning for whole course of far-range cruise torpedo.
