BLADE FOR ORTHOGONAL TURBINE OF WIND- AND HYDRAULIC PLANTS Russian patent published in 2024 - IPC F03D3/06 F03B3/12 F03D1/06 

FIELD: wind power engineering.

SUBSTANCE: blade for orthogonal turbine of wind and hydraulic plants has aerodynamic profile formed by its upper and lower surfaces. On the lower surface there is a cavity with maximum depth of 10...14% of the maximum height of the blade profile. Blade has a Kline–Fogleman profile KFm-3 with three steps on the upper surface. Between the upper surface and the point of maximum thickness of the blade at a certain distance from the surface a curved plate is attached to the blade, forming with this surface a confuser-diffuser channel. In front of the blade tip on the rotary hinge, the axis of which is fixed on the lateral sides of the blade, there is a rotor for distribution of the input flow along its upper and lower surfaces.

EFFECT: increasing power generation in orthogonal turbines.
