The invention discloses a flexible shell deformable skin for a folding wing, and relates to the field of flexible structure design of morphing airplanes, the flexible shell deformable skin is of an annular structure with an airfoil profile cut on an elastic thin plate, the middle part is hollowed, and the upper edge and the lower edge of the annular structure are equal in width, and the annular structure comprises an airfoil front edge, an airfoil rear edge, an airfoil upper edge and an airfoil lower edge; the wing-shaped upper edge and the wing-shaped lower edge are of strip-shaped structures; the airfoil upper edge and the airfoil lower edge are made into wave shapes in the direction perpendicular to the plate surface, and a plurality of wave shapes of straight line sections, wave crest sections, straight line sections, wave trough sections and straight line sections are formed in the length direction. The deformable skin of the flexible shell can be used for folding the wing and replacing a skin structure near a folding shaft, solves the problem of continuous and smooth surface deformation on the basis of large deformation of the wing skin, and has the advantages of bearing capacity, high designability and easiness in processing.

    本发明公开了一种用于折叠机翼的柔性壳可变形蒙皮,涉及变体飞机柔性结构设计领域,本发明为在弹性薄板上切出翼型剖面,中间部分挖空,留下上缘和下缘等宽的环状结构,所述的环状结构包括翼型前缘、翼型后缘、翼型上缘和翼型下缘;翼型上缘和翼型下缘为条状结构;将翼型上缘和翼型下缘在垂直板面方向做成波浪形,沿长度方向形成若干个直线段‑波峰段‑直线段‑波谷段‑直线段的波浪形。本发明的柔性壳可变形蒙皮可用于折叠机翼,替换折叠轴附近的蒙皮结构,在机翼蒙皮大变形的基础上,解决表面变形连续且光滑的问题,具有承载能力,可设计性强,易加工。
