摘　　要：通过对扇翼飞行器采用风洞试验的方法,研究横流风扇在不同风扇转速、来流速度、迎角、前缘开口角和叶片安装角下的升力、阻力和需用功率,得到相关的试验数据,并进行了处理分析。结果表明:风扇转速是影响扇翼升推力的主要因素,不同迎角和来流速度下扇翼的气动特性也不相同,前缘开口角和叶片安装角对扇翼的气动特性影响也比较大。本试验进一步验证了扇翼的工作原理以及获得控制扇翼飞行器升推力的方法,为大尺寸扇翼无人机的设计制作提供技术支撑。The wind tunnel test method is adopted for the fanwing aircraft to study the lift, drag and required power of the cross flow fan in different fan speed, velocity, angle of attack, front opening angle and blade installation angle. The results show that the speed of the fan is the main factor affecting the rise of fanwing force, the fanwing aerodynamic characteristics in different attack angle and flow rate are not the same, and the effects of front opening angle and blade angle of fanwing on the aerodynamic char- acteristics are relatively large. The fanwing working principle and the method for obtaining lift thrust of fanwing are verified by the wind tunnel experimental data. It provides technical support for the design and fabrication of unmanned aerial vehicles with large size fanwing.
