某型舰载反潜直升机悬停缆位角需求分析

Requirement Analysis of Hovering Cable Position Angle for a Shipborne Anti-submarine Helicopter

科学确定缆位角稳定范围对提高舰载反潜直升机反潜作战效能具有重要意义。针对某型舰载反潜直升机悬停使用吊放声纳时受阵风和洋流的影响易发生拖缆的现象,建立阵风对直升机悬停影响的数学模型,以及洋流对缆位角影响的计算方法,对不同角度阵风对舰载反潜直升机姿态变化导致的缆位角变化进行仿真分析,得出了在常见阵风和洋流条件下舰载反潜直升机缆位角的变化范围,可作为舰载反潜直升机确定缆位角稳定范围的参考。

It is of great significance to scientifically determine the stable range of cable angle for improving the anti-submarine combat effectiveness of shipborne anti-submarine helicopter.A ship borne anti-submarine helicopter was prone to towing cable under the influence of gust and ocean current when it hovered with suspended sonar.The mathematical model of the influence of gust on helicopter hovering and the calculation method of the influence of ocean current on the cable position angle were established.The simulation analysis of the change of cable position angle caused by the gust of different angles to the shipborne anti-submarine helicopter attitude change was carried out,and the common gust and ocean current were obtained.The variation range of cable angle of shipborne anti-submarine helicopter could be used as a reference to determine the stable range of cable angle.
