FIELD: wind power engineering.
SUBSTANCE: group of inventions relates to the field of wind power engineering, to wind engines with the axis of rotation perpendicular to the air flow. Efficiency of inventions is achieved due to the blade, which is a three-dimensional volumetric geometric figure formed by truncation of a secant plane along the line of the greater axis of a straight elliptical hollow cylinder, which is limited in the bases by planes, wherein said blades are connected to wheel by their lateral cylindrical surfaces. Windmill rotor is a device formed by connecting cylindrical surfaces into a wheel of blades in the form of a three-dimensional geometric figure formed by truncation by a secant plane along the line of the major axis of a straight elliptical hollow cylinder, limited at the bases by planes, in the required number, in one plane, equidistant from axis with creation as a result of rigid structure combined with axis of windmill, also limited in bases by disks, which additionally hold and concentrate wind flow. Technical result is achieved by concentration of wind energy in volumetric blades connected to a wheel, in which there are no openings between blades and losses of wind flow, and lateral, convex side of each blade redirects air flow to an open opening of an adjacent blade.
EFFECT: invention efficiency is achieved.
