| 摘 要： | 利用CFD软件对涵道风扇进行虚拟仿真，对共轴反桨双旋翼涵道风扇的空气特性进行分析。通过改变双旋翼的间距及飞行速度条件下仿真，对共轴反桨双旋翼涵道风扇气动特性的分析。结果表明，涵道距离对涵道扇有拉力有影响，但并不明显。在扰流的影响下，上桨盘产生的升力要小于下桨盘所产生的升力，并且涵道风扇不适合高速飞行。

| Abstract: | Use of CFD software virtual simulation for the ducted fan,analysis of the air characteristics of coaxial coun-ter-propeller ducted fan. Through the simulation under conditions of distance between the rotor and flight speed,analy-sis of the co-rotor axis ducted fan aerodynamic characteristics. The results showed that ducted distance ducted fan for pulling impact, but not great. Under the influence of burble, the lift generated on the upper propeller is less than the lift generated on the under propeller. The ducted fan is not suitable for high-speed flight. |
