Bionic drag reduction method for underwater vehicle and surface ship

Abstract

The invention discloses a bionic drag reduction method for an underwater vehicle and a water surface ship, and relates to the technical field of drag reduction methods, the bionic drag reduction method adopts a bionic outer skin structure, the water surface ship, the underwater vehicle and water immersion surfaces of the water surface ship and the underwater vehicle, the bionic outer skin structure comprises bionic grooves, bionic mucus holes and a flexible soft material, the bionic grooves and the bionic mucus holes are uniformly formed in the surface of the bionic outer skin structure, and the flexible soft material is arranged on the outer surface of the bionic outer skin structure; and the outer surface of the flexible soft material is detachably connected with the immersed surfaces of the surface ship and the underwater vehicle. The flow field structure of water flow is changed through the bionic grooves, the drag reduction of the underwater vehicle and the water surface ship is achieved, the drag reduction effect is improved in the process, meanwhile, the surface friction resistance is reduced, and the structure has the advantages of being simple, small in size, easy to operate and the like and is high in adaptation degree with the underwater vehicle.

Description

technical field [0001] The invention relates to the technical field of drag reduction methods, in particular to a bionic drag reduction method for underwater vehicles and surface ships. Background technique [0002] Surface drag reduction performance is one of the important indicators of underwater vehicles and surface ships. In order to improve the concealment and navigation efficiency of underwater vehicles and surface ships, their surface resistance should be reduced as much as possible. At present, there are still many deficiencies in the design of drag reduction for underwater vehicles and surface ships in China. [0003] There are following problems at prior art: [0004] Patent CN109611419A proposes a metal-based underwater imitation air film drag-reducing surface and its preparation method and application. The drag-reducing effect is performed through the micro-pit-like microstructure on the metal surface, but the drag-reducing effect is not good; the patent CN1096...
