Power characteristics of Savonius type wind turbines with various aspect ratio whose axes were inclined were examined experimentally. Turbine powers were found to decrease sharply with the angle of obliquity. This phenomenon was more notable for blowing up wind. High aspect ratio was effective to suppress this decrease due to angle of obliquity. Savonius type turbines with two stage buckets showed extreme power decline hardly depending on buckets phase.
