Modeling and Simulation of Airborne Depth Charge for Driving out Submarine
-
摘要: 非战争时期, 驱赶可疑潜艇是航空深弹的主要作战任务, 也是其自身特点和优势体现。首先, 在分析驱赶潜艇作战原则的基础上, 利用航空深弹爆炸威力模型和潜艇壳体抗冲击模型, 给出了深弹起爆时距离目标的安全半径和最大有效半径; 然后, 根据投弹散布模型和目标定位模型, 提出了驱赶潜艇目标的投弹瞄准点位置, 通过权衡完成驱赶目标任务概率和对目标潜艇造成毁伤的概率, 确定投弹瞄准点。最后, 针对声纳系统和磁探仪的不同目标定位条件, 仿真分析了具体算例。仿真结果表明, 较高的投弹精度和水下目标定位精度能更好地控制作战效果。Abstract: The underwater blast power model of an airborne depth charge and the resisting shock wave model of a sub-marine hull are employed to compute the safe-radius to the depth charge and the largest effective-radius based on the analysis of driving out submarine principle. A method to ascertain the bomb-dropping aiming point position is proposed according to the bomb-dropping dispersion model and the target location model, namely, the aiming point of bomb-dropping is determined by weighing the probability of accomplishing driving out target mission and the probabil-ity of destroying a submarine. In addition, some examples with different target location conditions of sonobuoy and magnetic anomaly detector are simulated, and the results indicate that better operational effectiveness control can be achieved based on higher precisions of bomb-dropping and underwater target location.
