Design and optimization of a biologically inspired flapping mechanism for flapping wing micro air vehicles

Abstract

In this paper, we investigate design and performance of a flapping mechanism which generates flapping motion through resonant excitation similar to flight apparatus of insects. The desired flapping motion is based on optimum aerodynamic efficiency. The mechanism is driven by a conventional motor and gearbox. The rotary motion is converted into oscilltory excitation through a four-bar linkage. This study explores the optimal design parameters of this mechanism for peak performance. © 2007 IEEE.
