摘　　要：采用无限片桨叶的固定尾迹分析法 ,建立了前飞状态下共轴双旋翼的固定尾迹模型 ,对共轴双旋翼的前飞气动特性进行了理论研究 .得到给定几何参数、桨盘间距和飞行状态下求解上下旋翼气动特性的完整算法 .The rigid-wake mode of coaxial rotor in forward flight was set up based on the analysis of infinite blade rigid-wake mode. The method of aerodynamic characteristics of coaxial rotor in forward flight was studied by rotor geometry, distance between upper and lower rotor and advance ratio. The theoretical results are in good agreement with the experimental data.
