A new patent under number 2854821 C1 for a new type of ship rotary wind propulsion device has been published in the FIPS database. The development is intended to improve the safety and efficiency of maritime transport, the rights belong to the Komsomolsk-on-Amur State University.
The design provides for the installation of a vertical hollow axis behind the ship's superstructure. Inside it, the exhaust gases of the main engine and diesel generators are placed. A rotor with pivoting blades is connected to the axis through bearings.
The rotor is driven by an electric drive powered by the ship's power plant. When the rotating surface interacts with the air flow, the Magnus effect occurs, creating additional thrust in the desired direction.
The pivoting blades regulate the movement of air inside the rotor and enhance circulation. The warm flow from the exhaust gases rises, cooling the structural elements and simultaneously enhancing the aerodynamic effect.
Placing the unit in the stern maintains a clear view from the wheelhouse and reduces risks when maneuvering in narrow passages and ports. In addition, the scheme does not require laying long cable routes along the ship's hull.
