Design, Fabrication, and Performance Test of a 100-W Helical-Blade Vertical-Axis Wind Turbine at Low Tip-Speed Ratio

Autor: Dowon Han, Young Gun Heo, Nak Joon Choi, Sang Hyun Nam, Kyoung Ho Choi, Kyung Chun Kim

Publikováno v: Energies, Vol 11, Iss 6, p 1517 (2018)

A 100-W helical-blade vertical-axis wind turbine was designed, manufactured, and tested in a wind tunnel. A relatively low tip-speed ratio of 1.1 was targeted for usage in an urban environment at a rated wind speed of 9 m/s and a rotational speed of
