This paper explores the complexities of a dragonfly's flapping wing motion. It includes the literature as well as analytical results using simulations done in COMSOL Multiphysics® software. The study depicts the Fluid-Structure Interaction of the 2D wing (airfoil) with air, governed by Naiver-Stokes equations. The wing follows mathematical functions and is given motion similar to dragonfly's wing. In this paper, a single wing is simulated to analyze the lift and drag over it, and then the study is optimized with the addition of another wing, flapping in 180 degree phase difference with the first one. The results obtained give us a glimpse of how the lift is generated by the wings. The results encourage further studies that can be done in this field.
