Bladeless Wind Turbine: Principle, Analysis, Scope, and Comparative Study with Conventional Wind Turbines

Abstract Bladeless wind turbines represent an emerging alternative to conventional horizontal-axis and vertical-axis wind turbines for sustainable energy generation. Unlike traditional wind turbines that rely on rotating blades, bladeless wind turbines operate based on aeroelastic phenomena such as vortex-induced vibration and oscillatory motion. This technology aims to address major limitations of conventional turbines, including noise generation, bird mortality, high maintenance requirements, and reduced efficiency in low wind-speed regions. This paper presents a comprehensive technical study of bladeless wind turbine systems, including their working principle, aerodynamic behavior, structural dynamics, energy conversion mechanism, and performance characteristics. A detailed comparison with conventional wind turbines is provided in terms of efficiency, environmental impact, scalability, and applicability. The scope, challenges, and future research directions of bladeless wind turbine technology are also discussed, highlighting its potential role in decentralized and urban renewable energy systems.
