A wind-powered generator includes a housing having an inlet, an outlet, and a throat that are coaxial about an axis of symmetry of the housing. A nacelle includes a first rotor mounted on a first end of the nacelle and positioned at least partially within the inlet, the first rotor outputting a first power output, and a second rotor mounted on a second end of the nacelle, the second rotor being positioned at least partially within the outlet and having a diameter less than the first rotor. The second rotor outputting a second power output. The first and second power outputs are combined to provide a combined power output, and a nacelle ratio between outer diameters of the nacelle at the inlet and at the outlet is between about 1.60-1.70, and a housing ratio between inner diameters of the housing at the inlet and at the outlet is about 1.85-1.97.

Provided is a wind power installation for converting the kinetic energy of the wind into the mechanical energy of rotation of a rotor for subsequent conversion of the mechanical energy of rotation into the electrical energy. A wind power installation includes a support frame, a shaft disposed on the support frame, and a blade system mounted on the shaft. The shaft is configured to rotate about a vertical axis and is functionally connected to an electric generator. The support frame is configured to be mounted between at least three radially arranged structures. The wind power installation can include additional blade systems disposed one above another on the shaft. Mounting the support frame between three radially arranged structures results in greater rigidity and robustness of the wind power installation, thus enabling the use of blade systems having a larger blade area and the arrangement of several blade systems on the shaft.
