Abstract
The performance of the orthopter-type wind turbine in a shear flow was investigated. The orthopter-type wind turbine is one of the vertical-axis wind turbines (VAWT) which each blade combines a rotating movement around its own axis and a rotating movement around turbine's axis. The diameter and height of wind turbine were 510mm and 400mm, respectively. The number of flat plate blade was three. The experiments were carried out in an open circuit wind tunnel. The effects of the location of wind turbine and the strength of shear flow on the performances of the orthopter-type wind turbine were found. The power of the wind turbine increased when porous plate installed the backward side.
