涵道风扇无人机结构设计

Structure Design of Ducted Fan Unmanned Aerial Vehicle

根据涵道风扇无人机的结构布局要求,以三维软件CATIA为载体,经过计算、分析、修正设计出涵道风扇无人机总体结构,包括涵道体外壳、内旋翼、操纵系统。整个结构设计过程,综合考虑系统空间、结构强度与质量等约束,以及选材、工艺的先进性与合理性等因素,是综合协调、折衷权衡、反复迭代、逐渐逼近的过程。涵道风扇无人机已经完成了系绳飞行和自由飞行,具有良好的自主悬停能力,验证了结构设计方案的正确性与合理性。

Based on preliminary configuration and parameters calculation, the primary structure of the flying robot has been finished using the CATIA design software, Based On the research of ducted fan, the aerodynamic characteristics of the flying robot are studied by means of combination of momentum theory and blade element theory in this paper. An aerodynamic mathematical modeling of the ducted fan and wings has been established, including ducted fan body, the rotor, upper-center, lower-center, stators and control vanes. According to the design scheme of ducted fan flying robot, configuration and preliminary parameters are analyzed and determined finally The tetherred flight test and the free flight test proved that micro rotary-wing aerial vehicle has the ability to autonimously hover and validate the design.
