Abstract
Disclosed herein is a blade bucket structure for Savonius turbines. In the blade bucket structure, blade buckets on which resistance resulting from the flow of fluid occurs, are provided with a separated flow retardation means for reducing pressure drag force impeding rotation of a Savonius turbine. The separated flow retardation means can reduce resistance that acts in a direction opposite to the direction of rotation of the Savonius turbine because of variation in orientation of the blade buckets while rotating.
