摘　　要：为了研究偏航阻尼器对垂尾飞行载荷的影响,将偏航阻尼器模型与飞机动力学模型相结合,建立了垂尾飞行载荷分析模型。以某型民机为研究对象,对其典型巡航状态下偏航机动、横向离散阵风、发动机失效和往复蹬舵情况进行了计算分析。结果表明,偏航阻尼器可大幅降低飞机横侧向运动参数响应幅值,4种状态下的垂尾载荷均有较大程度降低。In order to analyze the influence of civil aircraft yaw damper on vertical tail flight loads,this paper combined the yaw damper model with the aircraft dynamics model and established an analysis model of vertical tail flight loads.A civil aircraft was taken as the research object,the examples of yawing maneuver,lateral gusts,engine failure and rudder reversal during cruise flight were calculated.The results indicate that the yaw damper can greatly reduce the response amplitude of aircraft’s lateral motion parameters.The vertical tail flight loads are all greatly reduced in the four cases.
