Abstract

The invention belongs to the technical field of ships, and discloses a ship and an appendage structure thereof. The ship appendage structure comprises a framework, a shell and a buoyancy material, theshell is fixed through the framework, and a cavity formed by the shell and the framework is filled with the buoyancy material. According to the ship and the appendage structure thereof, noise generated during advancing can be restrained, and the underwater relative weight can be reduced.

Description

technical field [0001] The invention relates to the technical field of ships, in particular to a ship and its appendage structure. Background technique [0002] The ship appendage is used to improve the flow field around the hull and improve the speed and maneuverability of the ship without changing the existing ship shape. In the prior art, the ship appendage mostly adopts a cavity permeable structure, which is mainly composed of an internal metal skeleton and an external metal shell plate, with a cavity permeable structure in the middle. The water-permeable structure of the cavity in the middle will generate excitation during the sailing process of the ship, which will cause the cavity to vibrate and generate large noise. Contents of the invention [0003] The invention provides a ship and its appendage structure, which solves the technical problem in the prior art that the water-permeable structure of the ship's appendage cavity is noisy during travel. [0004] In ord...
