Analysis of Elliptical Wing Type Bird Inspired Device

Abstract

Technology advancements have made the use of Unmanned Aerial Vehicles (UAV) in many applications. This paper aims at performing stress analysis of elliptical wing type birds using ABAQUS. The wings considered for investigation are elliptical wings of two birds having low aspect ratio. Aerodynamic forces like lift and drag are calculated and applied on proposed wing design CAD models to obtain results of stresses and structural deformation at different altitude. The material used for wing structure is carbon fiber for its various advantages over other materials. Further, shape optimization of wing structure has performed to reduce the stresses at critical regions and to reduce volume of material. This wing design analysis helps designers to build UAV in optimizing manner. In addition to above investigation, various flapping wing mechanisms 2D in SAM and 3D in ADAMS have made based on curves that are obtained by tracing the tip of wings of selected birds in TRACKER.
