FIELD: power industry.
SUBSTANCE: sailing windmill includes the first and the second sections of blades, each of which has three to five radially located similar blade parts. Sections of sailing windmill are located one after the other and connected at their centre so that rear hub is formed. Each of blades is formed with the specified bending which is determined with ratio of axial distance between rear hub and front disc, which is 0.75 to 0.85 of length of blade from its connection point to rear hub to the end of blade, which is attached to front disc; at that, ends of each blade opposite their connection to rear hub are fixed at equal radial distance at equally spaced points about front disc. Rear hub and front disc of sailing windmill are fixed on the shaft, and shaft comes out either from rear hub or from front disc or from both of them; at that, support for attachment of shaft is provided so that its free rotation is provided.
EFFECT: effective wind or water energy conversion at simple design and economy in the production.
