Résumé
Vertical-axis wind turbines (VAWT) with 1 pair of semi-cylindrical and overlapping blades have an uneven torque. The work is based on wind tunnel experiments on experimental models that still contain a couple of auxiliary blades. The model has several levels and constructively the role of the blades changes from one level to another. The experiments in the wind tunnel confirm the important effect of the levels with changing the role of the blades until the complexity of accomplishment increases.
