N2 - Exhibiting rapid response, light weight, and large voltage-induced deformation, dielectric elastomer actuator (DEA) is a good candidate to drive flapping robot. We designed a flexible wing driven by dielectric elastomer (DE) and performed an aerodynamic analysis. Computational fluid dynamics (CFD) method is used to study the influence of the passive deformation of the wing on the aerodynamic forces during the flapping, and conducts selections of the airfoil. According to the CFD simulation results, concave-convex wing can generate larger thrust force comparing with other airfoils, when the deformation of airfoil is considered. The concave-convex airfoil has better aerodynamic performance can be chosen as the shape of the airfoil. Furthermore, their thickness and camber were optimally selected by analyzing the aerodynamics.
