Abstract

A camber-morphing wing based on a deformable truss is proposed in this paper. And then the structural analysis of the proposed camber-morphing wing is achieved. Compared with the existing concept of camber-morphing wings, the deformation mode of this wing is easier to manufacture and implement in engineering. Due to the fact that the wing is driven by multiple motors, it has the characteristic of multiple degrees of freedom in camber-morphing, which can achieve various deformation controls. Establishing corresponding finite element models, the deformation ability under different driving conditions is simulated. The results indicate that compared with driving short metal wires, driving long metal wires results in a greater degree of trailing edge deflection due to a greater driving force. Based on finite element analysis of deformation capability, the camber-morphing wing exhibits satisfactory deformation capability. Furthermore, based on the analysis of load-bearing capacity, it is indicated that the camber-morphing wing has sufficient load-bearing capacity.
