Low-water-resistance submarine

Abstract

The invention discloses a low-water-resistance submarine. The low-water-resistance submarine comprises a submarine body. The low-water-resistance submarine is characterized in that a drainage channel is formed in the submarine body in the extension direction of the length of the submarine body. According to the low-water-resistance submarine, the drainage channel is formed in the submarine body, the underway submarine forms negative pressure in the drainage channel, partial seawater at the front end of the submarine flows through the outer surfaces of the two sides of the submarine body, the other part of the seawater rapidly passes through the drainage channel in the submarine body and is directly discharged through the tail of the submarine body, the seawater passing through the outer surfaces of the submarine is reduced, the low water resistance of the underway submarine is obviously reduced, and the cruising speed of the submarine is increased.

Description

technical field [0001] The invention relates to the technical field of submarines, in particular to a submarine with low water resistance, which is beneficial to speeding up the sailing speed of the submarine. Background technique [0002] In existing submarines, a propeller is installed at the tail, through which a force is exerted on the water, and at the same time, the reaction force of the water is used to push the submarine forward; however, in order to reduce the water resistance when the submarine advances, the front end of the submarine is set in an arc shape However, the above-mentioned traditional submarine still has the following deficiencies: (1) The arc-shaped front end design of the submarine can reduce water resistance to a certain extent, but due to the large size of the submarine, sea water will still flow from the front end of the submarine. Its outer surface slides backwards, that is, the contact area between the front end of the submarine and the seawater...

Problems solved by technology

[0002] In existing submarines, a propeller is installed at the tail, through which a force is exerted on the water, and at the same time, the reaction force of the water is used to push the submarine forward; however, in order to reduce the water resistance when the submarine advances, the front end of the submarine is set in an arc shape However, the above-mentioned traditional submarine still has the following deficiencies: (1) The arc-shaped front end design of the submarine can reduce water resistance to a certain extent, but due to the large size of the submarine, sea water will still flow from the front end of the submarine. Its outer surface slides backwards, that is, the contact area between the front end of the submarine and the seawater is still relatively large. Therefore, the traditional submarine is still affected by relatively large water resistance, which affects the speed of the submarine.
