High power generation efficiency due to increased inflow wind speed (World No. 1)
● "Lens Wind Turbine" Here are the key points! (1) High power generation efficiency due to increased inflow wind speed (World No. 1) (2) Reduction of noise generated by tip vortices (Effect of the round ring) (3) Improved aesthetics due to the round ring of the lens ● High Efficiency Power Generation The flared diffuser draws in wind due to its low-pressure area. The accelerated wind is increased by about 1.5 times at the blade tips, turning the turbine. Since wind energy is proportional to the cube of wind speed, a wind turbine with the same rotor diameter can achieve about 2 to 3 times the power output. ● Quiet Operation The tip vortices generated at the blade tips and the counter-rotating vortices induced by the inner wall of the diffuser cancel each other out as they move downstream, suppressing the tip vortices that are the source of aerodynamic noise, significantly reducing noise levels. Noise measurements for a 3kW machine recorded sound pressure levels below 55dB near the turbine at wind speeds of 5 to 14 m/s. Noise is not a concern even in quiet residential areas. ● Aesthetics Unlike conventional wind turbines with pointed tips that rotate at high speeds, the soft image created by the "ring" of the diffuser surrounding the blades does not detract from the landscape and blends easily with the surrounding scenery.
