Modular wing structure of unmanned aerial vehicles

Abstract

A modular wing structure for an unmanned aerial vehicle (UAV) is disclosed, comprising wing modules that can be detachably mounted on the fuselage of the UAV using connecting components. The wing modules are mounted within the connecting components via their main wing spars. Multiple wing ribs, located on the main wing spars, are distributed on both sides of the fuselage. Each wing rib has a paper wing skin covering at least the top of its outer edge, forming an aerodynamic airfoil profile that provides lift. This modular wing structure and its paper wing skin improve maintenance flexibility and reduce costs. The spacing of the multiple wing ribs on the main wing spars can be freely adjusted to regulate the torsional stiffness of different wing sections. Furthermore, it ensures that aerodynamic forces during flight are evenly distributed and transmitted to the multiple wing ribs and the main wing spars, preventing the paper wing skin from tearing due to excessive localized stress.
