Magnetic current propulsion system for underwater vehicle surface

Abstract

The invention relates to a magnetic current propulsion system for an underwater vehicle surface, and belongs to the technical field of underwater vehicle power. The propulsion system comprises magnetic strips, a water pushing surface, positive electrode strips, negative electrode strips, an electrode strip base layer and magnetic nails. The electrode strip base layer is arranged in the water pushing surface, the positive electrode strips and the negative electrode strips are embedded in the electrode strip base layer, the electrode strips are arranged in parallel, and the magnetic nails are arranged between the positive and negative electrode strips; the seawater constitutes load, the load is the seawater on the water pushing surface between electrode lines and dipole plate strips, the magnetic nails are located below the water pushing surface, a magnetic line of force is perpendicular to the water pushing surface, when the seawater in a magnetic field is energized, a Lorentz force isgenerated to push the seawater to move, the water pushing surface densely covers the whole surface of an underwater vehicle, and the resistance of the surface water of the underwater vehicle is transformed into the driving force of the surface water of the underwater vehicle to push the underwater vehicle to move so that deep sea cliffs can be avoided, a propulsion mode of the underwater vehicle is completely changed, the propulsion mode is more energy-saving, the source of underwater vehicle noise is completely eliminated in principle, and the propulsion system has great potential for development.

Description

Technical field [0001] The invention relates to a surface magnetic current propulsion system of a submarine, which belongs to the technical field of submersibles. Background technique [0002] Submarine is a kind of submarine, and the construction of submarine is an important research topic. Submarines mainly rely on sonar for search and combat. Therefore, even conventional diesel-electric submarines need to be equipped with anti-vibration rubber and anti-vibration springs on diesel engines, main generators, main motors and other equipment to reduce vibration. There are two main noise sources for nuclear submersibles: one is the main cooling pump unique to the pressurized water reactor of nuclear reaction, and the other is the reducer of the main steam turbine. In all current submarines, propellers are used for propulsion, and the propeller type cannot replace the noise source. At present, there is no better way to reduce the high-speed rotation of the turbine from thousands of...
