ORTHOGONAL TURBINE (VERSIONS) Russian patent published in 2017 - IPC F03D3/06 F03B13/10 

FIELD: power industry.

SUBSTANCE: orthogonal turbine according to the first embodiment contains the curved along the cylindrical helical line, at least one blade with an aerofoil profile in its cross-section, at that the blade is mounted across riding on it the air or water flow with ability to rotate around the axis of the cylindrical helical line, and the input edge of the aerofoil profile is directed towards the blade rotation. The blades ends are fixed relatively to the shaft, mounted with ability to rotate, coaxially to the cylindrical helix coil axis and connected to the electric generator shaft, the blade ends are fixed relatively to the shaft by means of the cantilever beams. The shaft is formed by two half-shafts, each is connected with one of the cantilever beams and is mounted on its support, the blade is curved without intermediate supports along the cylindrical helix with a constant radius of curvature, so that in each cross section the aerofoil profile of the blade is formed at the acute angle to the circle tangential, traced by the entry edge of the blade airfoil profile, and that the blade ends are rotated relatively to each other by 360°. The second embodiment differs from the orthogonal turbine of the first embodiment in that, the blade is fixed relatively to the shaft with one of its ends by means of the cantilever beam, at that the shaft is mounted cantilevered at the support, the cantilever beam is provided with the counterweight of aerodynamic shape mounted cantilevered on the shaft.

EFFECT: efficiency increase of the orthogonal turbines with airfoil blades by increasing the efficiency of the fluid power conversion, namely the water or wind flow power.
