The expediency of use of slow-speed (multiblade) wind-wheels with sail-type blades on the territories with low wind potential is substantiated. The structure of experimental prototype of horizontal-axis wind0wheel with sail-type blades is proposed. The technique of determination of blades inclination angles influence on the starting torque of the wind-wheel is presented. The obtained results are analyzed and the expediency and feasibilities of the wind-wheel largest sailing capacity ensuring with a view to obtain the largest starting torque under the small wind speeds are substantiated.
