反潜直升机吊声搜潜悬停探测飞行模型

Hovering Detection Flight Model of Helicopter in Submarine Searching with Dipping Sonar

针对反潜直升机使用吊声搜潜时需悬停探测的问题,基于反潜直升机悬停探测飞行过程、最短飞行路径准则和几何原理,规划反潜直升机悬停探测飞行路径,并考虑风对反潜直升机飞行状态的影响。对建立的飞行路径进行了数学求解与分析,最终给出悬停探测飞行数学模型。根据建立的悬停探测飞行数学模型,对单机圆形应召搜潜的飞行路径进行仿真验证,仿真结果表明,悬停探测飞行数学模型可以更加真实地模拟反潜直升机吊声搜潜的实际飞行路径。

To the problem that the anti-submarine needs hovering detection in submarine searching with dipping sonar,we planned a flight path for the anti-submarine helicopter hovering detection based on the hovering detection flight process,the shortest flight path standard and the geometric principle with consideration of the impact of wind on flight status. Analysis was made to the flight paths,and the mathematical model of hovering detection flight was presented. The flight path of single-helicopter round call-search was simulated based on the mathematical model. The simulation results show that hovering detection flight mathematical model can simulate more realistically the actual flight path of anti-submarine helicopter when searching submarine with dipping sonar.
