Design and Numerical Analysis of Characteristics of Energy Kites

Abstract

As worldwide demand for renewable energy sources grows, novel solutions are required. Airborne wind energy (AWE) is emerging as a viable frontier, using high-altitude winds to generate sustainable electricity. Energy kites represent a promising technology for efficiently harnessing wind energy, which uses a tethered aerial system to gather and convert wind energy into electricity. This study delves into the design and numerical analysis of energy kites to understand their operational principles and performance metrics comprehensively. The design process involves considerations of aerodynamics, structural mechanics, and energy conversion mechanisms. Advanced numerical simulations are employed to investigate parameters influencing efficiency in generating electricity from high-altitude winds. Aerodynamics are crucial for energy kite performance with airflow patterns, lift and drag forces, and optimal angle of attack being key factors. This research takes a multidisciplinary approach to essential areas, using sophisticated techniques like computer-aided design (CAD) modelling and aerodynamic simulations. The dynamic pressures and strains experienced throughout the traction and retraction phases are examined to find flaws and provide improvements, assuring the energy kite's reliability, safety, and operating efficiency. Detailed aerodynamic computations are used to better understand airflow dynamics around the energy kite and its components, with an emphasis on the airfoil SG6042. Structural mechanics ensure the kite's integrity and durability under varying wind loads. The CAD model supports decision-making and iterative design modifications, which improves system performance. Numerical simulations analyse pressure distribution, deformation patterns, and fatigue behaviour of components like the tether and wings. The study of energy conversion properties is aimed at improving performance and ensuring economic feasibility. This research on energy kite design and numerical analysis provides insights into aerodynamics, structural mechanics, and energy conversion mechanisms. It attempts to develop airborne wind energy by combining theoretical research, aerodynamic characteristics, effective energy kite designs, and computer simulations. By advance understanding through simulations, the study contributes to the development of airborne wind energy systems for a sustainable future
