WIND MOTOR Russian patent published in 1995 - IPC

FIELD: wind power engineering. SUBSTANCE: wind motor has wind wheel 2 made up as a shell, which is arranged concentrically to vertical shaft 3 and is defined by two mated convex part of cylindrical surfaces, and pair of blades 5,6, which have wing-like cross- section and are coupled with the shell. The inlet edges and sides of the blades exposed to the wind are made up as parts of cylindrical surfaces. The radius of cylindrical surfaces of the shell is 1/3.3 - 1/3.6 of the diameter of the wind wheel. The eccentricity of the curvature center of each of the surfaces is equal to 1/4.5 - 1/5 of the wind wheel diameter, preferably 1/4.72. EFFECT: enhanced efficiency. 12 cl, 4 dwg
