摘　　要：针对直升机拖曳猎扫雷装备搜扫航路过渡问题,提出了搜扫过渡的三种方式;通过对反水雷直升机转弯飞行特性的分析,结合拖曳猎扫雷装备水下转向运动的实际情况,建立了直升机拖曳猎扫雷具转向过程拖体运动模型,避免了运用流体动力学分析拖体坐标的复杂性,提高了计算速度;最后,对三种不同飞行状态下直升机拖曳猎扫雷装备搜扫航路过渡进行仿真实验,结果表明:随着直升机飞行速度的提高,拖体迅速向直线航路靠近,这一结果与实际一致,证明了模型的正确性,研究结果能够较真实地反映拖曳猎扫雷具在直升机转向过程中的运动轨迹,可为反水雷直升机航路优化和反水雷方案制定提供决策依据。Concerning the issue of route-transition by helicopter towing arming of mine-hunting and mine-sweeping, three patterns of route-transition were put forward. Through analyzing the swerve characteristics of helicopter and the real movement of underwater towed cable system, the kinematic model of swerving process was established, the complexity of fluid dynamics was avoided and the calculation rate was advanced. Finally, the correctness was testified by examples of three flight states by helicopter towing arming of mine-hunting and mine-sweeping. Through increasing velocity of helicopter, the underwater towed cable system was fast close to the beeline sea-lane, the result was in accordance with the real movement. The trajectory of swerving process of route-transition by helicopter towing arming of mine-hunting and mine-sweeping was truly reflected, and the result can be used for decision-making of route optimization and operation scheme.
