摘　　要：本文研究直升机旋翼挥舞运动的变化规律和操纵规律,以桨叶挥舞运动的微分方程为模型,分析研究桨叶挥舞运动中旋翼拉力保持不变,且旋翼保持的挥舞状态,以及影响旋翼挥舞状态的因素。同时,直升机在悬停的基础上以前推杆为例,找出旋翼挥舞角的变化规律和旋翼锥体的倾斜方向变化规律,为分析旋翼挥舞中的实际飞行问题提供理论依据。This paper investigate the movement act of helicopter rotor flap and thd control rule.Using the mathematics model that is a blade flap motion differential equation,it is investigated that rotor thrust hold the line in blade flap motion and rotor is in fixed flap state,and the factors affecting on rotor flap state.Moreover,it is finded that the movement act of rotor flap and rotor cone tileing direction when helicopter is hovering with pushing rod.It will offer theory base to analyes rotor flap problem appearing in flight.
