The use of wind turbines for small-scale and urban applications is a topic that is receiving increasing attention. The use of wind turbines for small-scale and urban applications is a topic that is receiving increasing attention. This work concerns the Savonius rotor. It is divided into three parts. The first one consists in an original experiment which has led to the direct measurement of the pressure field on the blades of a rotating Savonius rotor. In the second part, the results are introduced in a generalized model to calculate the efforts which generate the vibrations at the rotor supports. This study explains well the vibratory behaviour of the rotor. Finally, in a third part an experiment analysis of an adequate system of a suspension to stabilise or avoid these vibrations is proposed. This study explains clearly the vibratory behaviour of the rotor.
