反潜直升机侧翼伴随巡逻搜潜建模与仿真

针对反潜直升机侧翼伴随巡逻搜潜阵位配置依据不足、实际对潜警戒扇面动态变化的问题展开研究。通过分析理想条件与舰艇编队规避机动2种情况下的敌潜艇鱼雷发射阵位,得出侧翼搜潜阵位配置的定量依据;根据舰艇编队航行中反潜直升机搜潜扇面的动态变化过程,建立了反潜直升机侧翼伴随巡逻搜潜的实际警戒扇面模型,并对兵力需求进行了分析。最后仿真计算了侧翼搜潜阵位的配置以及实际对潜警戒扇面范围。结果表明:配置单架反潜直升机于舰艇编队侧翼12nmile处,可对舰艇舷角60°~100°范围内的扇面实施有效对潜警戒。

Modeling and simulation of antisubmarine helicopter flank-accompany patrol search

Aimed at the shortage of position deploying basis and dynamic changes of defense sector against submarine, flank-accompany patrol search by antisubmarine helicopter is investigated. The position of enemy submarine launching torpedo is analyzed in two situations: ideal condition and formation evasion maneuver condition. Then the deploying quantitative basis of flank antisubmarine search position is given. According to the dynamic change process of antisubmarine search sector in ship formation navigation, models are built to calculate valid defense sector of flank-accompany patrol search by antisubmarine helicopter. The demand of antisubmarine force is also analyzed. Finally, different deploying positions of antisubmarine search in flank of ship formation are simulated when submarine torpedo launching position changes and also simulated valid coverage angle of defense sector against submarine with different parameters. Results show that deploying a single antisubmarine helicopter to 12 n mile at the side of ship formation could cover ship relative bearing from 60° to 100°.
