This paper presents experimental studies in a wind tunnel of a two – coherent cross – section blade of wind rotor with vertical axis, mechanism of locating the direction of the wind and planetary rotation of blades. A structure of the blade and results of measurements of aerodynamic forces and aerodynamic torque were shown. Based on received results under some assumptions the propelling moment and unit power were obtained. The results are presented in figures.
