Magnetic flow propulsion system of underwater vehicle with outer surface provided with water pushing ditch grooves

Abstract

The invention relates to a magnetic flow propulsion system of an underwater vehicle with the outer surface provided with water pushing ditch grooves, and belongs to the technical field of underwater vehicle power. The magnetic flow propulsion system comprises magnetic strips, the water pushing ditch grooves, electrode wires, dual pole plate strips, dual electrode plate base layers and electrode wire fixing strips. The dual electrode plate base layers are laid on the outer surface of the underwater vehicle. The dual pole plate strips are embedded in the base layers. Each magnetic strip is arranged between every two corresponding dual electrode plate base layers. The magnetic strips are arranged in a mutually-parallel mode. Seawater forms the load, as for the seawater, between the electrodewires and the dual pole plate strips, in the water pushing ditch grooves, a magnetic field N pole is above the water pushing ditch grooves, a magnetic field S pole is below the water pushing ditch grooves, the seawater in a magnetic field generates Lorentz force under the situation of energizing to push the seawater to move, the water pushing ditch grooves are densely and fully distributed in theouter surface of the whole underwater vehicle, and resistance of the water on the outer surface of the underwater vehicle is converted into propulsion force of the water on the outer surface of the underwater vehicle to push the underwater vehicle to move, a propulsion mode of the underwater vehicle is completely changed, more energy is saved, the source of noise of the underwater vehicle is completely eliminated from the principle, and the magnetic flow propulsion system has great development potential.

Description

technical field [0001] The invention relates to a magnetic current propulsion system with water pushing grooves on the outer surface of a submarine, belonging to the technical field of submarines. Background technique [0002] Submarines are the most important type of submarines. At present, in order to detect submarines, the navies of various countries have equipped hydrophones on ships, aircraft, submarines and even the bottom of the sea to monitor the surrounding ocean noise, and then use noise analysis, signal processing and other means to judge The noise made by the submarine, and then attack the submarine. Like this, submarine noise has just become the maximum obstacle that submarine keeps concealment, and submarine just must reduce noise as far as possible if will bring into play its proper fighting power. [0003] The noise value of surface ships when sailing is generally 180-190 decibels (cruising speed of 16 to 20 knots), which is a very strong noise. The noise o...

Problems solved by technology

[0006] Judging from the current situation, it is impossible to eliminate the noise in principle by using conventional technical means to reduce the noise of the submarine. Therefore, it is necessary to adopt a new propulsion method of the submarine to improve the energy utilization rate of the submarine and reduce the noise.
