Abstract

This study is based on the development of a smart biomimetic flapping wing using composite materials. Its configuration is inspired by hummingbirds and is constructed with load distribution reflected by the deflections of the wings during flapping. Wing deformations are obtained using DIC technique. The fluid-structure interaction of the wing and the atmosphere is also numerically simulated. Results provide the stress distributions in comparison with the experimental counterpart. Flow fields also suggest that the stresses are related to the vortical structures at the leading and trailing edges. The analysis shows how simulation results supports the experiment measurements.
