The invention discloses a low-noise bionic flapping wing and a preparation method thereof. The flapping wing comprises a wing membrane and a wing vein. The flapping wing membrane is formed by attaching a low-permeability material membrane and a porous fiber material membrane, the two material membranes are placed up and down, and the wing vein is placed between the two material membranes, so that a low-permeability material membrane-wing vein-porous fiber material membrane composite sandwich structure is formed. The wing veins are divided into main wing veins, bifurcated wing veins, outline wing veins and arc wing veins; in order to improve the bending resistance of the wing, contour wing veins and arc wing veins are arranged on the boundary and the middle of the wing membrane respectively. The number of the main wing veins is five, the main wing veins are evenly distributed in a radial shape from the wing root to the wing tip, and the branch wing veins are in a three-branch form and are formed by branch from the corresponding main wing veins. According to the design of the flapping wing, a deformation mode generated by high lift force and high efficiency is maintained, wrinkle deformation during flapping of the wing is further limited, and low noise is generated.

    本发明公开了一种低噪声仿生扑翼及其制备方法,扑翼包含翼膜、翼脉。扑翼翼膜为低渗透率材料膜及多孔纤维材料膜贴合而成,两材料薄膜上下放置,中间放置翼脉,形成低渗透率材料膜‑翼脉‑多孔纤维材料膜复合夹心结构。翼脉分为主翼脉、分叉翼脉、外廓翼脉及圆弧翼脉;为提高翼抗弯能力,在翼膜边界和中间分别设置外廓翼脉及圆弧翼脉。主翼脉有五根,从翼根部向翼尖方向呈放射状均匀分布,分叉翼脉为三分叉形式,从相应主翼脉上分叉形成。该扑翼的设计维持了高升力高效产生的变形模式,又进一步限制了翼拍动时的褶皱变形,实现了低噪产生。
