Design and Verification of Variable Camber Wing Based on Cellular Structure

Cellular structure is an ideal way to realize adaptive flexible deformation of wings due to its lightweight, high stiffness, high building speed and reusable characteristics. On the one hand, the cellular structure can maintain the stiffness of the adaptive wing under aerodynamic loads, on the other hand, it can also be used as a driving structure to make the overall structure produce the expected deformation. In this paper, we designed a cellular variable camber wing, including cellular structure and drive system, and carried out modal analysis and static analysis of cells. The cellular structure is processed by 3D printing, and the wing assembly and drive system installation are finally completed. The deformation test of the variable camber wing is carried out by motor control. The results show that the deformation of the variable camber wing of the cellular structure is more flexible and can meet the requirements of the target deformation angle.
