摘要

摘要: 为解决对非等速直航目标的鱼雷射击参数计算问题, 研究了对可预测弹道目标射击参数计算的一般方法。对鱼雷弹道以分段增量的形式进行了表达, 给出了射击参数计算模型, 与对等速度直航目标射击的主要不同是需要解一个二元非线性方程组。针对理想声自导运动目标, 以微分方程数值解计算预测的目标状态, 用Newton迭代计算二元方程组的数值解。数值试验发现, 这一方法能快速准确地计算出射击参数, 可为解决鱼雷对非等速直航目标的射击参数计算问题提供参考。

Abstract: To compute torpedo shooting parameters for a straight running target with non-constant velocity, a general method for computing torpedo shooting parameter for a target with predictable trajectory is presented. For easy understanding and application, the torpedo trajectory is expressed in form of subsection increment, and a computation model of shooting parameter is established. Compared with the method for shooting a target with constant velocity, the proposed method needs to solve a system of nonlinear equations with two unknowns. For an ideal acoustic homing target, the numerical solution of a differential equation is used to compute the target state, and Newton iteration is adopted to compute the numerical solution of the system of binary equations. Numerical experiment indicates that this method can compute shooting parameter rapidly and accurately
