Structure for reducing the drag of a ship and its application

Abstract

A structure for reducing the drag of a ship and its application thereof is provided. The structure for reducing the drag of a ship comprising at least one turbulence generator which is installed on the side surface between the widest section and the aft end or on the bottom surface between the deepest portion and the aft end of the ship. The arrangement of the turbulence generator can generate turbulence to reduce the drag of the ship, and thereby increase the speed of the ship or reduce fuel consumption as well.

What is claimed is: 
     
         1 . A structure for reducing the drag of a ship and its application, comprising:
 a hull, comprising a fore end and an aft end, wherein a keel line is formed between said fore end and said aft end of said hull; and   at least one turbulence generator, provided on the side surface between the widest section and the aft end of said hull, or on the bottom surface between the deepest portion and the aft end of said hull, thereby the arrangement of the turbulence generator generates turbulence to reduce the drag of the ship while sailing.   
     
     
         2 . The structure for reducing the drag of a ship and its application according to  claim 1 , wherein the structure comprises a plurality of turbulence generators arranged adjacent to each other with a gap between them. 
     
     
         3 . The structure for reducing the drag of a ship and its application according to  claim 1 , wherein the structure comprises a plurality of turbulence generators arranged adjacent to each other as a stripe without a gap. 
     
     
         4 . The structure for reducing the drag of a ship and its application according to  claim 1 , wherein the turbulence generator has an impact surface, said impact surface has an intersection angle of not more than 60 degrees with the keel line of the ship. 
     
     
         5 . The structure for reducing the drag of a ship and its application according to  claim 4 , wherein said impact surface of the turbulence generator is parallel to the keel line of the ship. 
     
     
         6 . The structure for reducing the drag of a ship and its application according to  claim 1 , wherein the configuration of the turbulence generator is a rectangle, a slanted-face rectangle, a polygon, a trapezoid, a triangular pyramid, a pyramid, a cone, a semi-circular cone or a semi cone. 
     
     
         7 . The structure for reducing the drag of a ship and its application according to  claim 1 , wherein the turbulence generator is adhered, embedded or welded to the surface of the hull, or integrally installed with the hull. 
     
     
         8 . The structure for reducing the drag of a ship and its application according to  claim 1 , wherein the turbulence generator is made of metal, plastic, wood, bamboo, glass, ceramic or composite materials.
