Study of Performance Ratio of Newly Developed High-Performance Airfoil with Respect to the Airborne Wind Energy System

The harvesting and storage of renewable energy, particularly wind energy, has become crucial for the development of both developed and developing countries. Wind energy, harnessed through turbines, has proven its potential as a reliable and non-polluting energy source for the future; while wind energy offers significant advantages, a major drawback is the complex and challenging installation process. To address this issue, airborne wind energy system has emerged as a promising alternative technology which uses a system which captures the energy from wind at higher altitude and has reduced number of parts. In this context, this study focuses on to increase the efficiency of the airborne wind energy system (AWES), namely ground-gen by generating new airfoils from Clark-Y a base airfoil which have higher performance characteristics. Several airfoils are formed using the XFLR software by changing the camber and thickness of Clark-Y airfoil, and the airfoils with best modification based on the performance ratio which is ratio of coefficient of lift to coefficient of drag (Cl/Cd) were selected. Further attempt is made to generate new airfoil series, CITI series, from the result obtained by modification. The performance was tested based on the parameters like Cl/Cd ratio of the airfoils. Result revealed that the performance of CITI series airfoil increases by almost 26.92%.
