The results of experimental researches of velocity field are presented before a rotor, inwardly and after the revolved vertical axis scheme rotor with direct blades, performed in the low speed wind tunnel of АТ–3 KhAI. Expressions are written for relative normal and tangent components of the velocity got by means of permeable cylinder model. Comparison of experimental and theoretical dependences of relative resulting velocity from an azimuthal angle inwardly and after a rotor and relative component of velocity V_x from the coordinate of z before a rotor is shown.

Key words: vertical axis scheme rotor, Pitot-static tube, tip speed ratio parameter, circle solidity, coefficient of permeability.
