BLADE AND TURBINE UNIT Russian patent published in 2021 - IPC F03D3/06 

FIELD: energy engineering.

SUBSTANCE: invention relates to wind energy and is intended for production of work and energy directly from air moisture. A turbine blade for relative movement in a surrounding fluid and a turbine unit with at least one blade. The blade is comprised of a main spar with two protruding formations and discharge means configured to discharge the evaporating and condensing fluids outward into the surrounding fluid flowing over the main spar. The first of the protruding formations accelerates the flow of the surrounding fluid until it reaches the speed of sound. The Mach number continues to increase after the first protruding formation, wherein the evaporated fluid is discharged into the environment causing the air to cool thereby additionally accelerating the surrounding flow and decreasing the pressure. The lower pressure induces thrust on the second protruding formation. When the flow moves relative to the second protruding formation, the Mach number decreases and then increases upon descent over the second area. The condensed fluid is discharged inducing condensation of the water content in the air releasing heat, thereby decreasing the Mach number and increasing the pressure. The increased pressure on the second protruding formation creates thrust that can be used to rotate the rotor.

EFFECT: technical result is production of energy regardless of the wind speed, wherein the energy source directly depends on constantly available surrounding atmosphere.
