A variable camber wing based on composite corrugated plate flexible skins is composed of a plurality of wing sections, rotating shafts, hinge structures, composite corrugated plates and elastomer layers. The connection relationship is as follows: the wing sections are connected end to end through the rotating shafts, the composite corrugated plates cover between the adjacent wing sections, the composite corrugated plates are respectively fixed on platforms of the front wing section and the rear wing section, each hinge structure is arranged in the middle of each composite corrugated plate andis connected with the corresponding wing section, and the elastomer layers are adhered to the outer surfaces of the composite corrugated plates. The characteristic that the composite material corrugated plate flexible skins have large deformability in the corrugated direction is utilized to design the variable camber wing structure, out-of-plane constraint is applied to the composite corrugated plate flexible skins through the hinge structures, the wing can achieve the variable camber function, out-of-plane deformation outside the allowable range of the composite corrugated plate flexible skins can be avoided, and a good aerodynamic configuration can be maintained.
一种基于复合材料波纹板柔性蒙皮的变弯度机翼,由多段翼段、转轴、铰接结构、复合材料波纹板和弹性体层组成。其连接关系如下:各个翼段通过转轴收尾相连,相邻翼段之间覆盖上复合材料波纹板,复合材料波纹板分别固定在前翼段和后翼段的平台上,每块复合材料波纹板中部设有铰接结构与相应翼段相连,弹性体层粘接在复合材料波纹板的外表面。本发明利用了复合材料波纹板柔性蒙皮在沿波纹方向上具有大变形能力的特点,设计了一种变弯度机翼结构,并用铰接结构对复合材料波纹板柔性蒙皮施加面外约束,该机翼能够实现变弯度功能,且复合材料波纹板柔性蒙皮不会出现许用范围之外的面外变形,能够维持良好的气动外形。
