Abstract

The invention discloses a device mounted on ship for reducing sailing resistance, which comprises an air compressor arranged in the ship body and a bubbling pipe arranged on the outer side of the ship bottom along a keel line. One end of the bubbling pipe is connected with an air outlet of the air compressor by a pipeline. The bubbling pipe is located beneath the water surface. The device has the following advantages: 1, the device is used for reducing the friction resistance between the ship body and water, which is not as good as the air cushion manner but easier than the air cushion manner in implementation, the sailing speed of the ship is enhanced greatly without the great change on the ship body, and the fuel oil is saved in abundance; 2, the device is simpler and can reduce the friction resistance between the ship body and water in use, and the device can be used in various ships conveniently, even supersized ships and also can be used in the improvement of various old ships easily; and 3, the device only needs low cost.

Description

technical field

[0001] The invention relates to the technical field of aspects related to frictional resistance during ship navigation, and specifically refers to a device for greatly reducing the frictional resistance formed by water on a ship's hull during ship navigation. Background technique

[0002] It is well known that hovercraft can greatly reduce the friction between the hull and water, but due to the special requirements of hovercraft on the bottom of the ship, this method can only be used on some small ships, and it is difficult to apply to larger ships. And it cannot be used for the transformation of old ships. Contents of the invention

[0003] The purpose of the present invention is to install a bubbling device on the bottom of the ship by designing a bubbling device, and use the device to spread air bubbles to most of the places where the hull contacts with water, so that the contact between the hull and water is converted into the contact between the hull a...
