Conventional Savonius rotors have high coefficient of static torque at certain rotor angles and a negative coefficient … static torque from 0° to 360°, a helical Savonius rotor with a twist of 90° is proposed. In this study, tests on helical … of power for each helical Savonius rotor are measured. The performance of helical rotor with shaft between the end plates …
