HYBRID ROTARY WIND PROPELLER FOR SHIPS WITH ROTARY DROP-SHAPE BLADES Russian patent published in 2021 - IPC B63H9/02 

FIELD: auxiliary sailing equipment design.

SUBSTANCE: invention relates to the design of a device for auxiliary sailing equipment, namely to ship hybrid rotary wind turbines with rotary arcuate blades. Marine hybrid rotary wind turbine with rotary drop-shaped blades is a construction of an auxiliary sail armament, which consists of a cylindrical or conical multi-tiered rotor with open ends, mounted on a vertical or inclined mast, connected along one axis with a stock. The stock rotates in the bearings of the deck platform and the support column, and the cylindrical surface of the rotor is formed by standard-sized rotary teardrop-shaped blades with adjustable slot gaps between them, installed using axles and bearing bushings between the annular yards and the spreaders. The rotor for rotation does not require an external ship power source and a drive for its rotation, and the necessary torque for rotation arises due to the flow around the blades and the acceleration of the air flow in the slotted nozzles between them, and while the ship is underway, when the nominal speed of rotation of the rotor is reached, the excess torque by The stock can be generated via a gear pair, reverse gear and generator and sent to the ship's power grid.

EFFECT: high energy efficiency of the wind turbine is achieved.
