CYLINDRICAL WIND TURBINE Russian patent published in 2015 - IPC F03D1/06 F03D7/02 F03D5/00 

FIELD: power industry.

SUBSTANCE: invention relates to wind-driven power plants with the main shaft of a wind turbine, which is parallel to wind flow. A cylindrical wind turbine is installed on the shaft of the wind-driven power plant and includes blades arranged on radial rods. Each blade has an aerodynamic profile. The wind turbine is made in the form of a cylinder and installed on the main horizontal shaft. A bevel gear speed reducer and sleeves with bearings providing rotation of the main shaft are located on the same shaft. Surface of the cylinder adjoins front and rear wheels. Wheels consist of rims, hubs and radial rods. Hubs are fixed on the main horizontal shaft of the wind-driven power plant. Radial rods are flat-type. Radial rods attach rims of wheels to their hubs. Each of the heels has N>2 symmetrically located rods. Position of rods of the rear wheel is offset relative to rods of the front one at angle β. Angle β sets attack angle α for all N blades and is fixed by the hub of the rear wheel. On the rods there are attachment points of the closest side members of all N blades. N ribs are attached to similar points for attachment of rods on rims of both wheels. Opposite side members of the corresponding blades are connected to the ribs. To the rear edge of N blades there fixed by means of a hinge are flaps with loading planks on their lower edge and with stops coinciding as to direction with the lower plane of the blades.

EFFECT: simple and reliable design and absence of vibration noises.
