Abstract: A wind power unit, that uses the power of wind, is made as a support installed power-generating unit comprising at least one turbine with a nozzle apparatus mechanically connected to a generator, a central shell, an annular front shell having at least one input channel of the turbine that forms with the central shell an output channel of the turbine, and annular outside shell that forms with the central shell diffuser output channel. The power-generating unit is equipped with an additional annular shell forming with external surfaces of the front and central shells narrowing-expanding first intermediate channel connected in its intermediate part to turbine output channel, while, with the internal surface of the outside shell, a second intermediate channel connected long with the first intermediate channel is used to diffuse the output channel.
