Abstract
The purpose of this study is to compare aerodynamic characteristics of flight motion between rigid and elastic wing. Especially, in Elastic wing we investigate about wing of partially different Young ' s modulus. In order to this investigation, we used Fluid-structure interaction (FSI) analysis. In FSI anaiysis , fluid analysis employ finite difference method (FDM) and structure analysis employ finite element method (FEM). Computation of flapping wing motion are performed for various Young ' s modulus condition, we survey relationship between lift coefficient, thrust coefficient and displacement.
