Study on Aerodynamic and Structural Analysis of Bio-mimetic Corrugated Wing

Abstract

The aerodynamic and static structural analysis of a newly developed bio-mimetic corrugated aerofoil inspired by dragonfly forewing is included in this work. The basal wing part of the dragonfly corrugated aerofoil structure used in this study was placed around the radius of the forewing. These corrugations define the stressed skin structure, which is made up of grider-like veins and a thin cuticle membrane that provides a sophisticated mechanical advantage for longitudinal bending resistance while allowing for wing camber and torsion. Dragonflies are recognised for their amazing flight abilities. They are designed to carry both aerodynamic and inertial loads. At a Reynolds number of 15000, a computational analysis of a newly designed dragonfly corrugated aerofoil is performed, with flow assumed to be laminar, steady, incompressible, and two dimensional. The project includes static structural analysis and aerodynamic flow analysis of a 2-D dragonfly corrugated aerofoil utilising Ansys Fluent and Ansys Mechanical APDL. It has been discovered that the design criteria employed, as well as simulations performed on a corrugated aerofoil, produce significantly better results than earlier studies. The structural analysis also demonstrates that it can withstand maximum pressure loads and provides high rigidity to the wing span. This discovery adds to our knowledge of insect-inspired corrugated wing structure and facilitates the application for improved design of artificial wings for MAVs and UAVs.
