Submarine

Abstract

The invention relates to the technical field of submarine manufacturing, in particular to a submarine. The submarine comprises a submarine body, wherein two water inlets are symmetrically formed in the two sides of the front of the submarine body; water outlets are formed in the positions, corresponding to the two water inlets, of the rear of the submarine body; water cavities penetrating throughthe submarine body are formed between the corresponding water inlets and water outlets; the water cavities communicate with the corresponding water inlets and the water outlets, and drainage wheels are arranged in the water cavities. The submarine has a simple structure and a reasonable design, and the speed of the submarine is greatly improved, meanwhile, dividing and dispersing of concentrated vortexes are realized effectively, generating of cavitations of tip vortexes is restrained and put off, pulsating pressure and noise of the cavitations are reduced, the noise of the submarine is greatly reduced, and the concealment of the submarine body is enhanced.

Description

technical field [0001] The invention relates to the technical field of submarine manufacturing, in particular to a submarine. Background technique [0002] Submarines, or submersible ships, are ships that can operate underwater, but the design of the hull of the current submarine and the cooperation of the power plant cannot eliminate water resistance, and the speed of travel is not fast enough, and the speed of change of direction is not flexible enough, and Because the speed of the water flow on the blade surface of the rotating blade of the drainage wheel is different from that at the back of the blade, the pressure generated by the water flow on the blade surface and the blade back is different, so there will be a pressure difference. Because of this, the rotating blade generates thrust to work on the submarine. However, there will be tip vortex generation, the noise, vibration, cavitation and cavitation denudation produced by the tip vortex will pollute the environment ...

AI Technical Summary

Problems solved by technology

[0002] Submarines, or submersible ships, are ships that can operate underwater, but the design of the hull of the current submarine and the cooperation of the power plant cannot eliminate water resistance, and the speed of travel is not fast enough, and the speed of change of direction is not flexible enough, and Because the speed of the water flow on the blade surface of the rotating blade of the drainage wheel is different from that at the back of the blade, the pressure generated by the water flow on the blade surface and the blade back is different, so there will be a pressure difference. Because of this, the rotating blade generates thrust to work on the submarine. However, there will be tip vortex generation, the noise, vibration, cavitation and cavitation denudation produced by the tip vortex will pollute the environment and harm these devices themselves. To prolong their service life, the tip vortex must be reduced or eliminated, but the vortex It is produced together with fluid power. If you want to get fluid power, there must be vortex generation. Moreover, the current submarine is very noisy. The amount of noise is directly related to the concealment of nuclear submarines. The noise is loud and the concealment is poor, which is at a disadvantage in war. status
