PROFILE TO MAKE VERTICAL BLADES FOR VERTICAL-AXIAL WIND GENERATOR PLANTS Russian patent published in 2013 - IPC F03D3/06 

FIELD: power engineering.

SUBSTANCE: profile to make vertical blades of vertical-axial wind-generator plants has a scan in the form of a rectangular plate. One of the sides of the rectangular plates is bent by 135-170°. The area of the bent plate is equal to 1/2 of the area of the second plate, which forms the specified angle. The opposite side of the rectangular plate is bent by 10-45° to the opposite side relative to the first side. The area of the bent plate is equal to the area of the second plate, which forms the specified angle is common for both above angles. The profile at the ends is plugged with plates. Between the plates that form the above angles there are transverse partitions.

EFFECT: increased efficiency of vertical-axial wind-generator plants.
