The invention discloses a bionic flexible sawtooth-shaped covering feather which is made of a flexible silica gel thin film material and is of a long-strip-shaped structure, and sawteeth are evenly distributed on one side of the long edge of the feather. The invention further provides a fixed-wing unmanned aerial vehicle which comprises a fixed wing and further comprises the bionic flexible sawtooth-shaped covering feather, and the bionic flexible sawtooth-shaped covering feather is installed on the fixed wing in a hinged mode. The long edge is vertical to the chord length of the fixed wing. Self-adaptive vibration can be achieved under the effect of incoming flow, the flowing stall and eddy current noise phenomena can be effectively controlled, and due to the flexible silica gel material, the manufacturing cost is reduced, and meanwhile the difficulty of the installation technology is reduced.

    本发明公开了一种仿生柔性锯齿形覆羽,采用柔性硅胶薄膜材料制成,为长条形结构,在长边的一侧设有均布的锯齿。本发明还提供了一种固定翼无人机,包括固定翼,还包括上述的仿生柔性锯齿形覆羽,仿生柔性锯齿形覆羽安装方式为铰接在固定翼上;其长边垂直于固定翼的弦长。本发明能够在来流的作用下自适应振动,能够有效控制流动失速和涡流噪声现象,且灵活柔软的柔性硅胶材质不仅降低了制作成本,同时也降低了安装工艺的难度。
