Abstract
To improve rotation performance of vertical axis wind turbine, new blade profiles that can rotate turbine rotor in wide range of wind speed are proposed. This new blade starts-up rotation as drag-type rotor in low wind speed condition. In high wind speed condition it changes mounting angle 90 degrees and keeps rotation as lift-type rotor. Results obtained by numerical and experimental investigations suggested proposed new blade profiles have higher performance as compared with conventional blade profile.
