摘　　要：涵道螺旋桨的气动特性对涵道飞行器的动力性能有直接影响。对影响涵道气动特性的结构参数进行量化,采用单一变量法,对具有不同桨尖间隙、唇口半径、桨盘安装位置、涵道扩散角的涵道模型进行了计算流体力学(CFD)仿真研究,通过对流场结构及升力特性进行对比分析,得到了涵道螺旋桨结构参数对增升特性的影响规律。The aerodynamic characteristics of the ducted propeller have a direct influence on the dynamic performance of the ducted aircraft.The structural parameters that affect the aerodynamic characteristics of the culvert are quantified in this paper.By using the single variable method,the culvert model with different tip clearance,lip radius,disc installation position and culvert diffusion angle was simulated by computational fluid dynamics(CFD).By comparing and analyzing the flow field structure and lift characteristics,the influence law of the culvert propeller structure parameters on the lift increase characteristics was obtained.
