针对常规单旋翼带尾桨直升机，通过对尾桨挥舞运动方程、尾桨动力入流模型、旋翼和机身在尾桨处侧洗的分析与计算，探讨尾桨动力学模型中不同因素对于直升机整机直线飞行状态的配平和驾驶员操纵输入动态响应数值仿真精度的影响程度，为不同目的飞行数值仿真中尾桨动力学模型的选取提供参考．本文以ＵＨ６０Ａ直升机为算例进行了对比分析． Aiming at the conventional single rotor tail rotor helicopter, through analyzing and calculating the tail rotor wave motion equation, the tail rotor dynamic inflow model, rotor and fuselage side rotor wash at tail rotor, the paper discusses the different factors in tail rotor dynamic model for helicopter whole The calibration of aircraft linear flight status and the influence of the numerical simulation accuracy of the driver manipulated input dynamic response are provided for the selection of the dynamic model of tail rotor in different numerical simulation of flight. In this paper, UH-60A helicopter as an example for comparative analysis.
