Abstract

The invention provides a supercavitation underwater vehicle. The supercavitation underwater vehicle comprises a vehicle body and annular skirt sections; the vehicle body comprises a front-section conical part and a cylindrical part; a plurality of annular grooves are formed in part of the surface of the front-section conical part, the annular skirt sections are installed on the outer surface on the tail portion of the cylindrical part of the vehicle body, a plurality of annular air bags which are not communicated with each other are arranged in the annular skirt sections, and air supply holesare formed in the portions, outside of the tail portion of the cylindrical part of the vehicle body, in the air bags, and used for being communicated with the air bags and a cavity in the vehicle body; when the air bags are not inflated, the annular skirt sections do not protrude out of the outer surface of the cylindrical part of the vehicle body. According to the supercavitation underwater vehicle, by improving the structural design of the vehicle body, it can be effectively achieved that the supercavitation formed in the front section of the vehicle body is stabilized, the running resistance of the vehicle body is reduced, the noise is reduced, and the velocity of the underwater vehicle is increased.

Description

Technical field [0001] The invention relates to the field of underwater vehicles, in particular to a supercavitating underwater vehicle. Background technique [0002] An underwater vehicle is a vehicle that sails underwater, which can complete underwater exploration, detection and even military offensive and defense tasks. As ocean development is increasingly important today, underwater vehicles are increasingly being valued by various countries, and they occupy an important position in both civilian and military applications. For a long time, the speed of underwater vehicles has been low due to the high resistance of navigation; if the speed is increased, the local pressure on the surface of the vehicle will drop to the saturated vapor pressure of water, causing cavitation, which will bring adverse consequences such as vibration, noise, and erosion. , Causing unpredictable economic losses. Cavitation is a physical phenomenon that often occurs in human life and engineering appl...
