A new design of small wind turbine is presented. The proposed system consists of axial flow turbine, located in aerodynamically profiled ring shroud, and modern alternating current generator. Results of CFD three-dimensional modeling of the system operation are presented. System prototype (diameter 0.5 m) was tested in open air on a moving car and in wind tunnel of SPSTU. Experiments were carried out at different air velocities with the measurements of flow using hotwire anemometer and pressure pick-ups. The results confirm preliminary estimations and open possibilities to produce small wind turbine up to diameter 10m.
