ROTARY MAST WITH INNER SAIL Russian patent published in 2024 - IPC B63H9/04 B63B15/00 

FIELD: shipbuilding.

SUBSTANCE: invention relates to floating facilities with wind power plant. Rotary mast with inner sail with displacement from axis of rotation on both sides of virtual central mast located in the center of rotary support (RS) are installed on their platforms, supports of external masts are rigidly connected to each other and support blocks of twisted cables are symmetrically connected to them. All supports are also rigidly connected to each other with external masts, which form the inner sail area (ISA) between them. Inner sail area has at least one section extending from rigid outer mast with synchronized mechanism of its extension and tension of untwisted/twisted cables, and made with possibility of restriction in upper part by rigid reinforced joint (RRJ). Rotary mast with inner sail can be supplemented with a deviation device (DD) with a mechanism, allowing to perform radial deviation of one extreme support of the plane of the inner sail area together with the block supports of the cables around the opposite support and relative to the diametrical plane of the rotary mast with inner sail, and to fix the inner sail area in one of three positions: extreme clockwise; extreme counterclockwise and central. Fixed part of the rotary support in the form of a circle is rigidly connected to the hull of the floating craft, and the radially movable platforms can be moved or fixed by means of their mechanical drive. Cables are stretched between the tension winches installed on the radially movable base of the inner sail area, resting on the block-supports located on their platforms and are attached to the rigid reinforced joint.

EFFECT: enabling increase in the efficiency of the wind power plant of the floating facility in a wider range of suitable for use heading angles to the wind, improved controllability and automation of the wind-driven power plant, as well as possibility to adjust the wind-power plant thrust.
