可伸缩折叠式四旋翼飞行器设计

Design for the Scalable Folding Quad Rotor Aircraft

针对四旋翼飞行器的结构外形不便于随身携带的特点,进行了优化设计。通过分析四旋翼飞行器结构特点和飞行原理,设计出可自动伸缩、折叠的四旋翼飞行器平台,并进行强度校核,最后进行了三维仿真建模与模型制作和试验测试。结果表明设计的四旋翼无人飞行器实现了空中自动伸缩、着陆后手动折叠的功能,同时节省携带空间,达到了良好的效果。

The optimization design for quad rotor aircraft is completed in this article for its structural shape is awkward to car-ry.Through analyzing the structure characteristics and flight principles, a quad rotor aircraft platform that could automatically retract and fold is designed, and its strength is then checked, and finally 3D modeling simulation and experimental tests are conducted.The result shows that design of the quad rotor aircraft successfully achieves automatic retractable and manual fold-ing, and meanwhile could save the carrying space, thus it gets good effects.
