直升机外挂飞行中的飘摆问题

主要研究直升机外挂飞行中，由于操纵方式或直升机的稳定特性及外挂形式等原因，使直升机产生飘摆，飘摆会影响任务的完成及飞行安全、从飘摆的机理出发，重点分析飘摆产生的基本条件及横向飘摆产生的原因，以及县挂点位置、吊索长度、外挂物形状等对直升机和外挂物耦合运动的影响。并给出对飘摆的处置方法和预防措施。为保证飞行安全提供理论基础和实际飞行经验。

Lateral Oscillation of Helicopter with Sling Goods during Flying

Lateral oscillation of helicopter with sling goods could takes place during flying by many reasons, and could affect safety and normal operation. Based on oscillations's tenet, the produced conditions, and reasons that caused the oscillation, as well as the effect of the position of sling point, the length of slying, the shape of slying, etc, on helicopter sling goods coupling motion is analysed in this paper. Then it provides handling measures and preventive actions about oscillation of helicopter with sling goods.
