BLADELESS WIND TURBINE POWER GENERATION SYSTEM

Resumen de: WO2026047692A1

The present invention discloses a novel bladeless wind turbine power generation system designed to efficiently harness wind energy in environments where traditional large-blade turbines are impractical The system features a cylindrical hollow pipe with spiral air inlets, which initiates wind channelization. A bladeless fan, positioned at one end of the pipe, creates negative air pressure, facilitating continuous airflow through the pipe. This airflow is then directed through a series of concentric reducer pipes with strategically placed inlets, accelerating wind flow and enhancing pressure management. The wind is ultimately channelled into a motor where a rotating shaft converts the kinetic energy into mechanical energy, which is further transformed into electrical energy. The design minimizes noise, visual impact, and wildlife risks compared to conventional turbines. The invention is particularly advantageous for narrow or spatially constrained locations such as urban areas and valleys, offering a high-efficiency, cost-effective alternative to traditional wind energy solutions.
